3PCS SP1848-27145 Heatsink 4.8V 669MA Thermoelectric Cooler 40mmX40mm Cooling Peltier Plate Module for Semiconductor Thermoelectric Heatsink Generation

Over all it does what is supposed, good price , value for money

The TEC1-12710 Heatsink has proven to be a reliable and efficient cooling solution for semiconductor applications. With a 12V power supply and a 92W capacity, this Thermoelectric Cooler provides effective cooling for various projects. The 40mmX40mm size and compact design make it suitable for integration into small-scale electronic setups. The Peltier Plate Module operates seamlessly, offering consistent and precise temperature control for semiconductor devices. The heatsink effectively dissipates heat generated during operation, maintaining optimal conditions for semiconductor components. While the unit performs admirably, it's essential to note that proper thermal management considerations are crucial for maximizing its efficiency. In summary, the TEC1-12710 Heatsink is a valuable component for those engaged in semiconductor thermoelectric applications, offering reliable cooling performance in a compact form factor.

If you want to play around with Peltier coolers or experiment with Peltier or Seebeck effects, this is cheap enough. I clamped it between two CPU heatsinks, with a fan on the hot side (the side without the writing on it). As you can see in the photos, even without heatsink compound the effect is noticeable. The power draw was quite a bit less than expected, presumably this is because the plate itself was getting quite hot. At some point I'll pull them apart, put heatsink compound on and have another go.As a CPU cooler it's not the most efficient way to go about things as it's going to be drawing almost 100 watts by itself, so that's another 100 watts that needs to be shifted on top of the heat from the CPU, but if you absolutely have to drive that core temperature down more than can be done with a heatsink alone, well, it's an option.Definitely a cool little science experiment and something that could attract interest if showed off in a school Physics class.

A nice little plate that gets hot one side and cold the other when you pass a current through it.Needs a good heat sink to get the heat away and make the other side more effective. As used in portable fridges, etc.

I can’t give a very scientific review as I can’t find my thermometer to see how cold it gets. I attached a beefy 12V 7A power supply and stuck a large heatsink and fan on the hot side and it did indeed get cold within a short amount of time.Peltier devices aren’t very power efficient so you will need a 12V supply with at least 6A capacity to have any success.I don’t have a particular use for this device, I just wanted it to experiment with, so I don’t know if it will keep modern x86 CPUs cool. This is one of the areas earmarked for fiddling with!

Although the seller says this designed and intended for use as a power generation device, I bought it to use as a cooler to condense excess water from air in order to control humidity. Using it as a cooler, it needs a fairly beefy heatsink on the hot side, especially if you are not limiting the power being fed into it as the I2R losses will generate a lot of excess heat, which if not rapidly pulled from the hot side will just overheat the entire device. It works as expected and does what I bought it for, so no complaints. It wasn’t my intended application, so I can't comment on how well these work as thermoelectric generators, but an array of these heated by a solar reflector could make an interesting project.
