## Description

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

## Features

- SP1848-27145 4.8V 669MA semiconductor thermoelectric power generation
- Can be used for power generation, cooling or heating applications, these modules are manufactured specifically for power generation
- Model: SP1848-27145, Color: White, Lead Length: about 300mm, Size: 4x4x0.34 cm / 1.57x1.57x0.13 inch, Working Environment: -60~125℃, Temperature electromotive force (a): > 190x uV/ ℃, Conductivity: 850~1250Ω -1.cm-1, Thermal conductivity (K): 15~16x10-3-W/℃ cm.
- The temperature difference will appear on both sides of the 12 volt power supply cooling chip. When one side is cold and one side is hot, do not energize the refrigerator for a long time without a radiator. Otherwise, the inside of the refrigerator will be overheated or burn.
- When the thermal energy is discharged from the low temperature side through the thermoelectric power generation piece, part of the thermal energy flowing into the device does not exotherm, and becomes electric energy in the device, and outputs DC voltage and current.

    Cool (and hot) gadget for science demonstration
  

*by M***D on Reviewed in the United Kingdom on 7 February 2024*

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.
