They should call them peltier heaters. I put one in my hand for the first time tonight and turned applied a bit of current. I couldn't believe how much hotter it was than cold. I had to try hard to notice the cold side being any cooler, but the hot side, and the whole package, became hot fairly quickly.

Bottom line is they heat the hot side by taking heat from the cold side, and it takes energy to do that. That energy is added to the amount of heat you have to dissipate. In the end, it heats more than it cools. That said, it can still be useful and fun to experiment with. 👍

Please tell me which peltier element I should choose to cool the Xeon 2699v3 processor, which has a TDP of 145 watts. Since I'm not interested in extreme cooling to negative temperatures, I just need to keep it within positive temperatures to avoid condensation. The AI says it's enough to keep it above +13C and choose tec-12710 or 12715. And the main thing for me is below +75C. Because then the throttling starts and the CPU loses a lot of performance. Or will this idea not work at all normally, so I can install it and forget about it?

None. Peltier coolers are not ideal for cooling CPUs or similar high thermal loads. If you'd use a Peltier to cool the CPU, you'd need a cooler that can deal with the TDP of the CPU *plus* the heat generated by the Peltier cooler. You are facing around 400 W or even more heat... Just use a proper CPU cooler to cool the CPU.

I have seen a lot of videos where they mount portable air conditioners based on peltier cells but even though they look very good and efficient I always have the same question. Is this system viable to cool a room even if I have more than 8 cells. Something tells me no. But seeing your tests of different systems I have better clarified these doubts. Now my question is is it work to ventilate air let's say decently nice at a temperature below 25 degrees? What happens if I mount the system inside an container and the hot air is taken out of the room through tubes and the cold air is expelled out of the container through holes. It can work at least as a cold air fan?

Dear Scientist, during research about developing my own Peltier Cooling project, i found your very interesting videos about Peltiers and usage. I already learned a lot from your videos, but i think i am missing an important part of information (measurement) every time. Or, at least, i did not find it in your videos, in that case please direct me to the video or comments. This is my point, and correct me if i am wrong: I have seen in your videos that Peltiers have a "Sweet Spot" witch is determined by appling a certain Voltage and Amps. This "Sweet Spot" is defined by finding the lowest temperature after reaching equilibrium. I think, the lowest temperature is not the only characteristic to detremine the effectiveness of a Peltier element. The other characteristic i am interested in is how fast the Peltier can reach the lowest temperature. I think the temperature, and the time it takes to reach that temperature do not have to be linked to each other by definition. Peltier elements differ in the used materials and their construction. I think that because of that, some might have a Lower (better) minimum temperature, but at the same time not being so effective in the speed it reaches that lowest temperature (analogy: Amount of moved electrons vs speed of moving electrons). Could it be possible to do some experiments where time would be another variable to measure, keeping all the other variables the same. Because IF there is a relative difference in Cooling speed vs Minimal temperature, it would change the way a Peltier could be labelled as Effective or Powerful. So a Peltier having a Less good Minimal Temperature could still be more effective in moving/dissapating heat from the cold side and from that point of view be more powerful that a Peltier with the lowest temperature. Or, are my thoughts wrong ? Hopefully you get my point ;-). Awaiting your reply, keep up the good work !

Hi! Not for these two Peltiers, but for other 5 or so devices, I measured how long it takes to freeze a certain amount of water. That's something that might be interesting for you. I have videos of it on my Peltier related playlist. Of course, the "sweet spot" is just one of the many interesting parameters, but it's relatively easy to measure and control, so that's one of the main reasons why I did that. Also, the speed of cooling would depend on how I measure it. I cannot for example measure how long it would take to cool down the surface of the Peltier to -25°C while powering it with 3 V, because at such a low voltage, it will probably not reach it. So, for a comparison, it is not very simple. Also, measuring this at the surface of the cold side without any thermal load would not tell too many useful things about the real performance. It would be nice to either have a well-controlled artificial thermal load or a big chunk of metal (4*4*4 cm copper or aluminium) that I can use as a load. Maybe later I will do something along this line, but at this moment I don't want to invest time and money in it.

Hi, I got a wine fridge with peltier tec-12706. Changed it yesterday to the same peltier, as the old one was broken. The fridge is supposed to go down to 11°C but is struggling around 13-12°C. Upgraded the fan for more air. Do you have any recommendations of a better peltier? Want it to go down to at least down to 8°C. Been looking at TEC2-19006, Tec1-12703 and Tec1-12710 but I have no idea.
@CuriousScientist
@CuriousScientist 7 ай бұрын
Hi! Tec2-type of Peltiers are useless here as they are built for temperature gradient and not cooling power. 12703 is *weaker* than the 12706, so you should avoid it. 12708 or 12710 are better. However, they have a larger power need, and they also dissipate more heat. So if you go for anything different than the 12706, make sure that you power them correctly (enough current) and cool the properly. Keep in mind that you should not run them at their maximum rated current as they become very inefficient. They should be run somewhere between 8-11 V, depending on the system. The current will depend on which unit is used. I have dozens of Peltier-related videos. They probably have the answers to all your questions.

@CuriousScientist
@CuriousScientist 11 ай бұрын
It will probably overheat, and it will potentially melt the solder inside the Peltier cooler, which would lead to an open circuit or short circuit depending on how it gets destroyed. Also, the warmer its hot side, the worse its performance becomes... Peltier coolers **must be cooled**, they generate a lot of heat, and their ceramic plate is not the best in dissipation. So you need to provide a good amount of cooling to the hot side.

@@CuriousScientist The vital difference between science and junk-$cience, in context to whenever anyone claims something. It's like you said, "Do you think or do you know?" The kinetic power of autosuggestion in circular logic keeps many trying to fill in the blanks, but you asked them if really knew or were just putting a belief that they think they know, however the tone they used indicated they had some doubt and have not returned reply, in retrospect. It's like trying to get a politician to attend unscripted forms of debate, but how can they formulate educated enough legit decisions if they're of the preference to pretend to have the best in mind while making decisions on behalf of the lives of other people? They tend to see willful ignorance as a form of merely acceptable collateral damage and maintain a lack of accountability for their actions, which is why the mainstream news is like staring directly into the sun. We all saw mr bonesaw's smile and putin's smile as they high5'd eachother at that UN meeting after a journalist was reported as being deleted after walking into but not away from a saudi embassy, and look at em now right? Ok, that got into ethics and moral values of critical objective research. Anyways, thinking about peltier considerations, how to scale things up if needed be. Even experiments yet to be tried related to how peltier works. Maybe we can peltier the polar regions to regenerate what our planet needs to keep generating oxygen powered by the sun, perhaps geothermally even passively with no moving parts or power sources other than the velocity generated from vectoring cooled or heated airflow to a useful pressure. Maybe even check valves can use water pressure to regulate currents at key points to also help adjust temperatures, seems worth research.

I could blame the cooler's performance for this, but other, similar power Peltiers have no problem staying cool with the same cooler. So I am a bit lost. Thanks!

Storage temperature is the "shelf temperature", I assume. When it is not operating, it can be stored at different temperatures. Even if you shut it down suddenly, it won't suffer from thermal shock because you are supposed to use them with heat sinks and they provide large enough buffer so the temperature does not drop suddenly. Moisture is a worse enemy, but these devices are sealed properly.
