Copper for comparison would’ve been interesting

[@randgate]

I thought the same (not fact checked/Google): Thermal conductivity of natural diamond was measured to be about 2,200 W/(m·K), which is five times more than silver, the most thermally conductive metal. The value for pure silver 406, for pure copper is 401, for nickel 91 and for stainless steels around 16.

Diamond is used in high-quality thermal paste for CPUs in Computers. There was a small time where copper was used as well, but that was probably too expensive. Yes, copper was more expensive vs diamond. That's because the diamond industry (the ring variety) is a complete scam and you and I have been brainwashed since birth, because we can grow that shit ourselves the price has dropped, but not nearly far enough.

Much lower tensile strength than copper though. Much less resistant to shocks and would develop cracks, so water-cooled / portable devices are probably not a good idea.

[@DatHoasi]

Batman watching this before going up against Mr. Freeze: “Interesting”

[@user-jp5vk8ks7e]

That is also true, Diamond is very good at conducting heat but it the ice also melts because of the pressure that is exerted by the force you are inputting and the area it is released through, using the formula Pressure = Force / Area. As water is the densest form for water (not ice), pressure (an act of compacting a molecule to its denser form) will melt the ice. In fact, ice skating uses this method to have smooth motion. Water has these weird features because it has a special chemical bond (Hy drogen bond). During its liquid state, the water molecules bounce around and make and break these hydrogen bonds with other water molecules. However, as soon as you solidify it via turning it into ice, the water tries to maximises its hydrogen bond to have a stable orientation. This orientation traps "air"/"space" between it, making it lighter than water (hence, ice floats over water). Sorry for the nerdy behaviour, just wanted you to know 🤓

This is exactly why diamond dust is used in high performance thermal paste because it helps transfer heat very efficiently, keeping devices cool.

[@_zzpza]

I believe this principle is how "diamond testers" work, specifically the ones you see on watch maker forums where someone wants to check that the replacement crystal they bought really is sapphire glass and not regular mineral glass. The tester heats up the tip of the device and then measures the temperature drop when you press it against the material being tested and displays any temperature drop on the LED bar chart. If there's no temperature drop it's mineral glass, if there's a big temperature drop then it's sapphire glass.

[@ItsAsparageese]

Omg I did manage to find it Due to extensive research done by the League University of Science, diamond has been confirmed as the the hardest metal known the man. The research is as follows. Pocket-protected scientists built a wall of iron and crashed a diamond car into it at 400 miles per hour, and the car was unharmed. They then built a wall out of diamond and crashed a car made of iron moving at 400 miles an out into the wall, and the wall came out fine. They then crashed a diamond car made of 400 miles per hour into a wall, and there were no survivors. They crashed 400 miles per hour into a diamond travelling at iron car. Western New York was powerless for hours. They rammed a wall of metal into a 400 mile per hour made of diamond, and the resulting explosion shifted the earth's orbit 400 million miles away from the sun, saving the earth from a meteor the size of a small Washington suburb that was hurtling towards midwestern Prussia at 400 billion miles per hour. They shot a diamond made of iron at a car moving at 400 walls per hour, and as a result caused two wayward airplanes to lose track of their bearings, and make a fatal crash with two buildings in downtown New York. They spun 400 miles at diamond into iron per wall. The results were inconclusive. Finally, they placed 400 diamonds per hour in front of a car made of wall travelling at miles, and the result proved without a doubt that diamonds were the hardest metal of all time, if not just the hardest metal known the man.

I actually read about the thermal conductivity of diamonds a few days ago and I was thinking whether it is practical to make heat sinks for electronics using synthetic diamonds.

[@iiiiiiiiiiiiii3280]

The first thing I thought too. But even synthetic diamonds cost a lot.

[@markjacobson4248]

Hypothetically yes but realistically no. For something like a heat sink for a computer there are so many other factors at play that affect the end result. Despite being very hard, diamond is quite a fragile material. It's just like glass, which is harder than common steel but not even close to the durability. This means diamond exchange fins would have to be thicker, limiting surface area relative to aluminum or copper fins in the same volume. Furthermore, we already have heat pipes, which have a far higher effective thermal conductivity than diamond does. The only place diamond makes sense to be used in computer cooling, it is already being used in. That's in thermal interface material, I.E. thermal paste.

[@csn583]

Dream material for TIM, not useful for heat sinks.

[@Toxicity1987]

Would be interresting in some spechal cases, but heatpipes are still more effective than diamonds. Diamonds are like 2300W/(m·K) while heatpipes have at least 10kW/(m·K)

[@TLguitar]

​@@markjacobson4248 Heat pipes aside as they are combined with fins as far as I know, the fins of an aluminium (or copper) heat sink aren't usually thinner than what a diamond might be cut into (the diamond sheet shown in this video is 0.5mm, which is less than a lot of standard heat sink fins), so diamond, depending on type, being about 5-8 times more thermally conductive than copper should be able to conduct heat much more quickly while employing a similar form factor. Whether it is possible to combine them with heat pipes in a similar form factor is the question.

[@SkyChu0]

I’m definitely not particularly knowledgeable but I feel like that would be less useful than you might think. Overall heat conductivity would be limited by the slowest link in the chain so: * Electronics generating the heat wouldn’t necessarily pass heat to the spreader any faster * Similar to current heat spreader to heat sink connections, the imperfections in both surfaces would limit total conductivity i.e. needing thermal paste which will limit thermal conductivity * Not using thermal paste is still not an option as you just have insulating air pockets instead * At the end of the chain, you’re still trying to dissipate the heat to the low thermally conductive air so the heat capacity of the cooler would have more effect on the cooling capacity/ability of the cooler.

@@SkyChu0 if you slapped in diamond as a replacement to the copper we have now you'd be correct. You have to bond the diamond directly to the chips themselves, grinding away parts of the casing. The long term plan is to use the diamond as the substrate the transistors live on directly.

[@SkyChu0]

@@Dysiode sorry, my comment was more directed towards the original comment of the cpu heat spreader. My layman understanding towards your company's project at the moment can only see a reduction in heat clumping/hot spots rather than necessarily improved heat dissipation. Would the engineering be around combining the die and cooling solution into a "single" cohesive link? Are there engineering challenges around breakages due to the reduced malleability of diamond? Again, limited understanding of any of this so I just ask because I don't know.

Hold the diamond with something insulating, and then try to cut the ice.

Yeah, and for the same reason. It's a great conductor of heat, so it feels cold when you touch it

Ice is also the nickname of my favorite substance and the acronym for the group that took my gam gam away

[@holyfire11]

This is how peasants see reality and explain it. A small amount of heat may be transferring but thats not whats going on.... Its a process called sublimation. The pressure of the diamond against the ice causes its melting point to be different because thats what pressure does... The pressure literally causes the ice to melt.... This guy clearly only took highschool physics for one term and only learned about thermal energy and transfer lmfaoo.

[@arforafro5523]

Another thing he's not mentioning, ice is less dense than water which is widely known. What not a lot of people know is that applying enough pressure to ice can force it to turn into water even if it's temperature is still below freezing. Once the pressure let's up the water freezes solid again, you can do this experiment at home. Grab two ice cubes and press them tightly together then let go, they will stick as their borders quickly liquify then freeze again. I believe there's an experiment somewhere in KZbin as well, a huge block of ice has a string with weights attached to it hanging from the middle. As time goes on the string slowly works it way through the ice but there's no way to remove it as the ice freezes shut behind it.

A very good game where you need to understand the elements and physics interaction to survive. I find it very interesting that the only reason you can only survive mid-game is because you find a machine that do not follow the laws of conservation of energy... Very good demonstration of a system entropy. Just a small warning, you need a lot of time to play this game, and you need to be prepare to lose a lot 😅

Same basic reason diamonds are difficult (but not impossible) to light on fire.

[@Voodoo_Robot]

Fun fact: that steel blade is not cutting the ice becsuse it's sharp, but because when you push the blade it increases pressure on the surface of ice which melts it. That's how ice skates work. They melt the ice a little, the water works as a lubricant and you slide.

[@carmin.e]

wonder if you can make a diamond stove

[@sm79165]

[@justforplaylists]

Do you mean a stove made out of diamond or a stove that uses diamonds as fuel?

[@carmin.e]

completely diamond stove WITH DIAMOND FRYING PAN but diamond is not the fuel

[@justforplaylists]

​@@carmin.e From browsing the internet a bit: I guess diamond would be pretty nonstick, since it's a crystal. It won't get scratched because diamond is very hard, but it might shatter if you drop it. Being a good conductor of heat helps the pan heat up quickly. Since it's not ferromagnetic, it would need a ferromagnetic coating to work with an induction stove. Regarding specific heat capacity: At home, you want a pan that can store a lot of heat energy, because home stoves are uneven. Restaurants want pans that don't store too much so they can heat up quickly. Restaurants use aluminum which actually has a higher specific heat capacity, but can be made thinner. Home cooks use iron which has to be made thicker to store heat, but is cheaper. Diamond is about half as dense as iron, so a diamond pan would have to be twice as thick as a cast iron pan if you want to sear a steak at home, which would make it expensive. But if you're buying a diamond pan maybe you don't care about the price. If you're at a restaurant with a stove that can put out a lot of heat, or you don't need to store a lot of energy for what you're cooking at home, you can try to make a diamond pan with similar properties to an aluminum pan. It would have to be about 1.35 x thicker than an aluminum pan to store the same energy. But I think at that thickness it might be pretty brittle. Diamond has a low fracture toughness, because it's a crystal. You can get diamonds that aren't one piece of crystal, like the kind used for drill bits. I think you'd want to go with that, but the thermal conductivity might be lower, it's more porous so it might need a coating, and it's much less pretty. Diamond has a much lower autoignition temperature than iron or aluminum, but I think it's still high enough that there's not much risk of your pan catching on fire. I think ovens have some sort of insulation in addition to whatever metal they're made from, unless it's an old cast iron stove.

There's also the added factor that you have a thin edge focusing all the pressure on a smaller area. Not exactly cutting either as it is also melting which is likely what the steel blade was doing too.
