In this video, I test out a Thermoelectric cooler on the Raspberry pi 4 and it worked out really well even when the Raspberry pi is overclocked, it's actually the best cooler I’ve tested on the I so far.
This Cooler uses the Peltier effect and is actually classified as a solid-state active heat pump, It transfers heat from one side of the device to the other using electricity.
Basically when you apply power to the heatsink one side gets really hot and one side gets really cold.
The thermoelectric device I use in the video is a low power version but the cold side can still get down to 8 degrees celsius.

The cooler used in their video was designed to be attached to the back of a cell phone it has a rubber coating on the cold side and in my testing I haven’t had any condensation issues, I believe it has to do with the low power consumption “ when compared to other thermoelectric coolers” and the rubber coating that used on the cold side.

Its blackshark funcooler white. I use it as my raspi 4 server cooler and run it 24/7. You have to watch the condensation though since its lower than room temp. My approach is by using passive cooling case and strap the cooler on top of it, then clear the condensed water once a week.

@balls2bone 3 года назад

Sub-ambient cooling is not really recommended, even on desktop PCs. Condensation can collect and that can be seriously damaging. Go cold enough and that condensation can become ice. You'd have to keep a high level of load on CPU in order to keep it from forming condensation!

@griftgfx 3 года назад

Yup... entirely impractical.

@danis8455 3 года назад

could combine it with an system submerged in a nooconnective fluid. Or if you really wanna shoot high a vacum chamber.

@AdeptPaladin 3 года назад

@@danis8455 If the system is in a fluid, why do you need the cooler to begin with? The natural convection and heat sinking properties of the fluid itself would be more the sufficient in keeping the Pi cool under even strenuous loads. Plus, the added surface area would work wonders to let it bleed off any heat delta higher than ambient. Also, vacuums would make the cooling of the peltier given the current setup, impractical. It works off using air to cool the hot side, which isn't possible in a vacuum. Only radiation is possible, which would require an entirely cooling setup. What you could do is try and run it in a dry-air environment, which would make the possibility of condensation impossible.. except now you're introducing the increased risk of arcing and static electrical discharges. A better solution would be to coat the at-risk areas in silicon conformal coating. This would prevent the build up water directly on the components and reduce the risk of water-damage or shorting. Or.. set up the cooler to be regulated by the Pi itself. This would make the cooler more power efficient (it wouldn't need to be at max cooling except as temperatures rose, thus making it draw less power overall) and coupled with temperature monitoring would prevent it reaching sub-ambient temperatures. This however, is still very inefficient compared to a bog-standard heat-sink and fan combo except in limited application systems, where heat sensitivity is a limit compared to power draw.

@Djhg2000 3 года назад

Peltier coolers respond really well to water cooling. Just run it with an adjustable bench power supply so you can optimize the efficiency (efficiency decreases sharply with higher voltage).

Little remark 'bout measuring with An IR thermometer: the metal heat spreader on the SoC van reflect ambient IR, for reflective metals it's better to measure the surface while it's covered with a non reflective material in IR, eg Paper masking tape.

@ledhceb 3 года назад

What is incredibly practical is to use this with the HQ Pi camera. One of the primary sources of noise in low light cameras is thermal noise. Most high level astrophotography cameras use Peltier coolers. Some astrophotographers mod DSLRs with Peltier cold fingers. The HQ camera, while not in the same league, has shown promise for astrophotography and other low light work. A cheap Peltier cooler like this cooling the $50 HQ camera with a Pi 0W could make a phenomenal sub $100 astrophotography rig. And yes, I know, the pixel size, exposure time and readout mechanics of the HQ limits use in long exposure use. But for the price this would be great for stacking exposures.

@juliokam7710 3 года назад

I played a lot with peltiers and thermoelectric coolers, but with the objective of make a portable air cooler. The key is that the more cooler you put the hot side, more cool can put out on cool side (and lower temperature). For me, it was a pain, trying to isolate both side so doesnt interact across the sorrounding, and get the best perfomance out of the peltier. As a computer cooler... it is risky, but as more success this could have, more investigation will get this kind of tech.

@keithduffield5239 3 года назад

The reality is that you have thermal resistance between the actual IC Silicon Die and the outside case. You quickly get to a point of diminishing returns when cooling a chip. You could freeze the metal case with liquid nitrogen but the silicon will still get hot.

@yearls 3 года назад

@jong2359 3 года назад

You should buy a can of conformal coating. Mask off the components you want to cool, coat the board on both sides + edges of the board, unmask/mount the Peltier, and let it rip full blast just to see if condensation matters on a fully coated board.

@spideliciousx9822 3 года назад

Great experiment. If able to control and ensure no condensation gets on the board, it would be awesome. A good example of a neat chip cooling method, but practically not viable. (I know you already knew all of this and was just experimenting, the comment is not meant to be derogatory, just commentary) I’d suggest the low power state, but also a sustained heat applied to the cold side from the hot chip (non humid environment helps too) helps to keep condensation at bay.

Your cooler only needs to prevent thermal throttling when your raspberry pi it is overclocking. Buy a cooler that does that for you so if you ever do need to unlock more horsepower it is available. But you shouldn't overclock generally because it means your computer is running in an unefficient manner, yes it faster but while drawing increasingly more power. Think of your computer clock as a straight line and power as an inverse bell curve where at a specific frequency the power draw is most optimum
