SD-020-12 Peltier effect cooling thermoelectric cooler for refrigeration


Thermoelectric air conditioner operate by the Peltier effect (which also goes by the more general name thermoelectric effect). The device has two sides, and when DC current flows through the device, it brings heat from one side to the other, so that one side gets cooler while the other gets hotter. The "hot" side is attached to a heat sink so that it remains at ambient temperature, while the cool side goes below room temperature. In some applications, multiple coolers can be cascaded together for lower temperature.




Demension of SD-020-12 Peltier effect cooling thermoelectric cooler for refrigeration


Please note that the parameters provided below are for guidance only. OEM /ODM are acceptable.Welcome to share your opinion with us.



1. The hot side of the thermoelectric cooler is mounted on the outside of the box

2. Use four M4 screws with flat washers to lock and  fix the air cooler;

3. Products need to be installed vertically(Heat sink fin is vertical;

4. Avoid to external shock and damage.


Fan blades and heat sink need to be kept clean to reduce the risk of heatsink overheating and     

cooling power decrease.
