## Description

Product Description Feature： 1.Great DIY peltier kit for small space cooling in hot summer,used for plate cooling, test bench, pet bed cooling, such as chicken, little dog. 2.Save space,small size can be installed in anywhere,well made compact structure DIY peltier cooler kit,easy installation,long term use. 3.The DIY thermoelectric cooler with good cooling performance, No noise, no vibration, no refrigerant required. Specification: Material: Aluminum Power Supply: DC 12V Power Cnsumption: 72W(Under the condition of 12V voltage, the power can only reach about 70%.) Maximum Cooling Space:10L (300*180*200mm)volume. Size: Approx. 3.93 * 3.93 * 3.74inch How to install Wire: 1.Our DIY Peltier Cooler Kit Completely assembled. TEC1-12706 semiconductor chilling plate equipped with cool fan for better heat dissipation,so they should "run together". You don't need disassemble the device to sort the wires and don't need separate switch for each fan. 2.There are 6 wires,you can see 3 red wires(two fans+TEC1-12706 chilling plate)，you can twist and connect them together,connect the12v battery positive electrode;3 black wires twist together connect the12v battery negative electrode. Note: 1.The cooling space of the DIY Thermoelectric Cooler should not exceed 10L (300*180*200mm) volume.The better the seal, the better the refrigeration effect. 2.The Peltier Cooler can only cooling the cabinet of 10L volume when the refrigerator is empty (the refrigerator does not put anything), and the cooling effect is about 5-6 degrees lower than normal temperature. 3.Under the condition of 12V voltage, the power can only reach about 70%. 4.The reverse connection of positive and negative electrodes will cause the cooling surface to be hot. 5.Please contact us in time if you have any questions, and we will deal with them actively. 6.If you want a good cooling effect, the box must have a good heat preservation effect. It is very important to choose a suitable box. 7.Can't be used as an air conditioner, you should know the conservation of energy. 8.The cooling effect is related to the power supply. Some power supplies are lower than the actual ones. It is suggested to use a larger one, such as 12V 10A. Package Included: One Pcs Peltier Cooler Kit:1: Fan net cover 2: Cooling fan 3: Radiator 4: Semiconductor refrigeration film 5: Thermal insulation gasket 6: Conductive cold film 7: Conductive cooling fan

Review: good price but below average performance - This is the first peltier I’ve purchased and I’ve had a lot of fun with it. I also think it’s a good deal because you get a lot of heatsink for the price. However I don’t feel like the peltier module itself is efficient enough because it doesn’t get cold as quickly as I’d expect it to. But again for the price I cannot complain. I did an experiment where I took off the small heatsink to expose the cold side directly and put a drop of water. It took a decent amount of time for it to freeze even at full power with the large heatsink on and the fan on.
Review: barely gets cool to touch - i got this in hopes to use to cool a small cooler box after several hours in the temp in the box is the same as it was to start

*by K***E on August 10, 2024*

### ⭐⭐⭐⭐⭐ Don't forget about condensation
*by P***W on October 26, 2025*

Perfect project for cooling electronics, however must also deal with condensation in humid climate. Didn't take that into account and water produced fried components as it got onto the boards. Must channel water produced so it doesn't get into sensitive electronics.
