On an atomic level, temperature is created by the atomic structure vibrating. This vibration is caused by all particles in the material vibrating with electromagnetic and nuclear forces. This phenomenon is most visible when atoms slow down their "spin", or internal energy, the closer they reach absolute zero. Since there are two materials with different thermodynamic properties but similar electromagnetic properties, the electrons can be shared easily between the two materials while still maintaining two different specific heat capacities. Once an voltage is applied to the two materials the electrons can flow to the material that they are attracted to. This will cause the vibrating electrons to leave one material the void of the electrons while the other material gains the vibrating electrons. This lack of vibrating electrons is what causes the electron deficient material to drop in temperature while the electron rich material has many vibrating electrons on it increasing its temperature. This is why changing the voltage will cause the electrons to travel to the opposite material but having the same phenomenon. The difference in voltage between the two materials creates a difference between the electron density between the two materials which then causes a difference in the thermal reservoirs between the two materials. This temperature drop is what allows heat to travel across the materials and electrons do not carry any of the heat themselves.

@@spacejunky4380 Entropy could be the defined as the flow of heat between two thermal reservoirs, but this thermometric effect is what causes the difference in thermal reservoirs in the first place so there are several systems working in this example. You would need to define your system in order to define where the heat was flowing to define your average heat flow or flux. Degrees of temperature is a measurement of the material and not a amount of energy, it is a scalar value. Since heat is an amount of energy that travels in a system and not a measurement of a material property it can not be converted into a temperature. The reason it isn't a speed is because speed is also a measurement of a specific value like temperature. Heat flux has a rate and direction associated with it.

@Ryan Green Mass of an electron is negligibly small compared to atoms in crystal lattice... Normally heat is generated in a conductor when flowing electrons collide with atoms. Successive collision results in large momentum transfer thus atoms will more likely to vibrate with larger amplitude. Vibrating atoms which has more mass than vibrating electron is responsible for heat generation in a conductor. Secondly, If electron void is created then it'll get occupied by another electron bcoz of closed circuit connection... And if electron voids are d reason for cooling on one side, then a conductor having positive static charges also has electron voids.. why wouldn't that cool?

A Peltier module consists of two unique semiconductors, one n-type and one p-type, which are used because they need to have different electron densities. The alternating p and n-type semiconductor pillars are placed thermally in parallel to each other and electrically in series and then joined with a thermally conducting plate on each side, usually ceramic removing the need for a separate insulator (Jamakandi et al., 2020), when a voltage is applied to the free ends of the two semiconductors there is a flow of DC current across the junction of the semiconductors causing a temperature difference. As the electrons travels from P type material to N type material, the electrons hop to the higher energy state hence absorbing thermal energy (cold side). Then as the electrons travel from N type material to P type material, the electrons drop to the lower energy state and hence, dissipating thermal energy (hot side)to the surrounding environment. The higher is the rate of dissipation of heat, the cooler it gets inside the chamber (cold side of Peltier module) and increasing the efficiency of the cooling module proportionally (Badgujar et al., 2015).

the explanation of (how moving electrons through a thermocouple pumps heat) is: in order to have thermocouple u should have two different material wires and they should have different numbers of electrons orbiting the nucleus at different orbits (say 3rd for wire 1 and 6th for wire 2)..and the wires are jointed at their ends when u apply heat to the junction u r actually releases different amount of electrons from both wires and due to that difference u get the voltage difference and that is what we r using to measure temperature.. But.... when u apply voltage u r forcing the electrons to flow through the thermocouple and that is causing electrons from lower energy levels orbit to oscillate at higher energy orbits and vice versa. then an electron with its own energy is now orbiting at (Say) 3rd orbit and u put him to orbit at 6th orbit with its same amount of energy, it will oscillate much slower and the opposite will happen if an electron came from 6th orbit to 3rd... now we knew that due to applying voltage we ill make some electrons oscillate faster and the other oscillate slower and that movement is what we are sensing or detecting as heat ( higher oscillation means high temp. and vice versa).. i hope that could clarify something

Medhi, I live in south Texas where temperatures regularly clear 110F, and our greatest threat here is not cold, but actually dying from heat. Hence we spend breathtaking amounts of money and resources down here fighting back against the tremendous heat load. Other complicating factors are that as a society we do not build our cities with any consideration for passive or natural cooling, relying purely on the electrical grid. Also, I am told by HVAC engineers, that our universal building code is only written to handle 90F to pass C of O, resulting in new buildings failing our performance requirements by 15-25F. Add to that, the compressor-run AC which is our standard weapon is incredibly inefficient, as it must take electricity to turn all its various parts and move things around that don't even produce cooling. Then there is the compounding effect, as the more compressor driven ACs we have in use in hot places, the more we concentrate the heat yet further for the entire region (and the world of course). The Peltier device is one of our great hopes in this fight, because the transformation from raw heat (which we are dying in) to electricity that can then power secondary cooling devices is so much more direct, with no moving pieces.It also has the profound advantage of taking heat (which we need less of) and producing cool (which we need more of) without a waste stream of heat being blown out of 1.5 million windows. The problem (as Robert Murray Smith pointed out), is that they are cumulatively far too expensive to be viable in any great application as they now exist. What we need is an entire second roof of Peltier, which takes the blazing heat differential (absorbing the first volley of heat of direct sun), and converting this into voltage which can then run electrical cooling devices. (more direct and with higher yield--we hope--than taking the usable light through a solar cell and processing it into electricity then used for cooling...again, with heat exhaust.) We need a FAR more cost effective solution--10'x10' Peltiers, Peltiers the size of train stations and Wal-Mart roofs and Coca Cola plants--in order to stop the cycle of heating-for-cooling we currently practice.

The way I understand it is that the current through the different conductors causes electrons associated with atoms to accumulate at junctions where current passes from conductor A to conductor B, while free electrons and atoms with spaces for electrons (holes) accumulate at junctions where current passes from conductor B to conductor A. Where associated electrons accumulate, equilibrium causes the rate of dissociation of electrons from atoms to be higher than the rate of association of electrons to atoms. Since electrons absorb energy when they dissociate, there is a net absorption of energy at that junction and it becomes colder. Likewise, at junctions where free electrons and atoms that can accept electrons (holes) accumulate, electrons will associate with atoms faster than they dissociate. This releases energy, causing the junction to heat up. As electrons flow one way through the circuit, the holes "flow" the opposite way, resulting in an accumulation of both at certain junctions and a deficit of both at other junctions. I believe this is only possible when one conductor has more holes than the other and vice versa for free electrons in the other conductor (ie: conductor A is rich in holes and conductor B is rich in free electrons). This is a confusing topic, and one I don't fully understand myself. There are some great explanations on a forum by the University of Illinois at Urbana-Champaign titled "Q & A: How can the Peltier effect work?" I hope this helps if you were curious!

The reason your fan assembly didn’t result in a higher output is because you are pumping air INTO the system instead of continuing to draw the heat down away from the system. If the fan blades had been pushing hot air down, rather than cold air up into the fins, the low pressure air gaps between the fins would induct more cold air from the surrounding environment into the area where the heat is being dissipated from. This is essentially low pressure vacuum tech

Therefore, uses are minimal, but as technology improves, small devices like this might be able to power much more in the future, like watches and such.

My understanding is that heat is composed of 2 parts: atomic vibrations and vibrations of electrons that conduct electricity. One side of device is semiconductor with big electron potential energy and the other has low one. But they both have the same kinetic energy because they're at the same temperature. So when they two come in contact, potential energy is different, So electrons move from high potential energy state into a lower energy state from one semiconductor side to the other. So one side now has less electrons, aka less heat, while the other one gets hot electrons which because they came from higher potential energy state, release their energy as more heat. In essence, hot electrons physically move from one side of device to the other. When you put electricity through it, you are using voltage to move more electrons from cold side to the hot side. Electrons move from higher potential energy to lower one. Effectively, removing hot electrons from cold side and depositing them on the hot side. When you do it the other way around, you are pushing electrons from low potential energy to high potential energy. And you move hot electrons to high potential energy state. Hot electrons loose their kinetic energy, or their hotness which gets converted to potential energy. Now thermoelectric device has many of these junctions. Here's a little map to understand it better: HS - high potential energy semiconductor LS - low potential energy semiconductor ^ - wire up _ - wire down HS^LS_HS^LS_HS^LS_ so as you see, if electrons move from left to right, high potential energy hot electrons will deposit heat on the up side of low potential energy semiconductor. Then low potential electrons will move from down side to high potential energy state and will get cooler by loosing kinetic energy and transforming it to potential energy. So in this configuration, thermoelectric device will get cold on it's down side and get hot on it's up side. And when you put electricity in reverse, same thing happens in reverse. Low potential electrons ho to high potential through up wire and reduce heat on up side, and high potential electrons move into a low potential state through wire downwards, creating heat downwards. This is my understanding from places like Wikipedia and other sources. Important to note that this is not the same potential that comes from things like conduction band and valence band. It is some sort of affinity towards electrons that changes with different temperatures. I hope my explanation made sense.

How it works on atomic / quantum level? I can imagine situation as follow. The flat surface with current connected to opposite sides of the surface causes the flow of electrons. But due to the shape of the surface, the electrons create circular current movement - as in the coil. This circular movement also causes the magnetic field to "move" as in the coli perpendicular to the axis of the circular current. But what is different, that in the coil you don't have any obstacle on the way of the magnetic field (the interior of the coil is empty). Here you have the surface which is affected by magnetic field. Here are only my imagination further: the magnetic field slows down the frequency of the electromagnetic radiation of the surface (cooling) on one side and speeds up the frequency of radiation on the other side (heating). I can imagine this as an item positioned in the wind - it will get cooler faster because the "wind" is taking the energy from the obstacle. In case of your experiment, the "wind" is the magnetic field. And the energy is given back on the opposite (heating) side of the obstacle. Probably this could be proven experimentally by placing the same shape in the middle of the coil. If it cools down and heats up then this is the case. Please let me know what you think about it :)

I assume it works like laser cooling does, which is how they get the record lowest temperatures. Basically... By adding and removing energy at the right time, you force it to shed heat and get colder. So, I imagine this device is like a microwave for atoms in the circuit... Forcing one side to get cold and the other to get hot by making them gain and shed energy. There is a similar effect in Thermo Acoustics, where you can turn a flame over one end of a tube into vibrations in the tube from air moving from sound waves in tube then the tube makes different hot and cold sections until you have the output reach the other end of the tube... Either hot or cold depending on tuning of the glass tube and amout of heat and all that. May help to have an analog computer to tune and play with.

@Electroboom I think that the peltier effect ( cooling effect upon application of electricity) is due to the conduction bands of 2 different materials being slightly different from each other, We can try thinking it through with the example of an electron moving from a lower conduction band to a higher one. So if an electron is trying to move from 1 material to another, it will need to jump to a higher energy level, total energy is equal to kinetic + potential energy. The potential energy gained by the electron has to come from the previous material’s particles But since the inner shells should already be filled, none of them should be giving out energy by decreasing their energy level, thus only kinetic energy in loss. Meaning a very small temperature drop would be measured. This is just from what I managed to read online, I do not have much knowledge about conduction bands, but hopefully this helps :)

The Peltier works because the electrons which pass through the semiconducting material are jumping either down the band gap to a lower energy state (releases heat) or they jump up to the higher energy state which cools down the material ;) This works because the two semiconductors have band gaps with different energy levels (n-type and p-type doping).

3:18 - Spin caloritronics is a relatively new field of research and focuses specifically on the interaction of spins with heat currents, motivated by the continuing discovery of new thermoelectric effects. Two of the most fundamental thermoelectric phenomena are the Seebeck and Peltier effects. These effects couple heat, charge and spin in magnetic materials. The Seebeck effect describes the direct conversion of a thermal gradient to an electric voltage. Conversely, the Peltier effect is a temperature difference developed across a material in response to an applied voltage. At the atomic scale, this corresponds to an applied temperature gradient causing charge carriers to move from the hot to the cold side of the material, inducing a measurable voltage.

As the temperature raises, the molecules vibrate and some of that vibration can be acquired by the electron as energy to jump to the material's conduction band. If, after the jump, the electron faces electric potential, it will run through the circuit instead of release the energy as heat back to the material. So the electron will use the heat to jump and then will not "go back" to the same place, thus the heat will be "carried away".

I've been working with solid state Peltier devices for over 15 years. They are used for sample gas coolers to remove condensation from a gas sample stream for emission analyzers. They are very reliable and can be used in place of a compressor cooling system. The best way to control them is to use PWM . They must be mounted to a heat sink. The life will be shorten significantly otherwise. We've used an AD595 IC with a thermocouple as a feedback loop in the past. A thermistor with a digital control loop is the newer control scheme, but still PWM. You can also stack the Peltiers to increase the heat or cooling capability.

3:18 , I dont exactly know with a lot of details , just thought of sharing it. Actually whenever we talk about heat energy , it is basically a modified form of kinetic energy. For example imagine an adiabetic process with a moveable piston on the top of a cylinder containing a gas (or just normal air). If the piston is pushed inside, the temperature of the temperature of the air rises amd it becomes hotter. At the same time it is observed due to less volume available , the frequency of atoms colliding with walls of cylinder increases which increases the pressure resulting in increased speed therefore higher kinetic energy. The complete opposite happens in vice versa, piston is moved a little outwards, it cools the gas and it has less kinetic energy. Consider another example is heating any solid, atoms of solids are quite close to each other, so if we heat the solid, its atom vibrates and the oscillations contain kinetic energy. So basically heat energy is a result of kinetic energy and vice versa. In other words these both forms of energy are almost the same. So saying that electrons carry heat as they move is just another way of saying they have kinetic energy. I might be a little wrong though but as far as I remember what I studied , I just thought it might be helpful to someone. If you find anything wrong, please correct me.

I'd try turning that fan around, so it pulls air through the heatsinks instead of trying to push air through. I built a humidor that uses 6 peltier junctions ( 4 cooling, 2 heating ) to maintain my cigars at 69 degrees. I machined all the heat sinks using a cnc router. The hot side is huge, 4 inches on a side, and each heat sink has a PC style fan drawing air through the fins. The cold side heat sink is only slightly bigger than the peltier unit, and has a small 12v fan, also drawing through the fins. I use a PID controller to PWM the power to the devices with a 1 degree hysteresis. When building everything, I experimented with the push-pull fan configuration, and the pull configuration is easily more efficient. The best I can get though is about 40f between the hot side and the cold side.

Peltier thermoelectric devices are made with Semiconductors such as Tellurium and Bismuth. If the positive polarity of the supply is applied to the N material side, the negative polarity is applied to the P material side, the upper copper plate cools, while the lower one heats. If in this same cell, the supply polarity is inverted, that is, the negative polarity is applied to the N material side and the positive polarity to the P material side, the function of hot / cold is reversed: the upper part heats and the lower one cools. So, basically one type of semiconductors have a lot of electrons and the other none (very few) which means that when you push voltage through, they attract each other... this is what generates the temperature difference.

Applying electricity can cause cooling because there is a net movement of charge carriers away from the side that is cooling down. Both electrons and holes are pulled away from the cooling side by the current flow. A net movement of energy carrying particles away from a surface must cool it down. It's weird to consider the absence of an electron as an energy carrying particle, but in the context of doped semiconductors it works. The alternative is trying to model the movement of all the gazillions of densely packed electrons, which is both A) hard, and B) ultimately cancels down to the movement of an electron hole anyway. The build up of heat on the other side does eventually result in a diffusion of charge carriers opposed to the current flow, which is why the temperature difference maxes out. The absolute temperature continues to increase through resistive heating and other effects.
