Features High Cooling Efficiency: Semiconductor coolers are a form of solid state cooling that incorporates both semiconductor Technologies and electronic assembly techniques, Use better and more difficult refrigeration tablets, easily cooling down within a few minutes, ideal for small area cooling. Easy Installation: The module semiconductor kit include semiconductor cooler and other accessories, compact size can be installed anywhere. Although the volume is small, it is sufficient and save material, easy installation and convient to use. Wide Application: The DIY electronic semiconductor refrigeration kit for electronic enthusiasts in semiconductor cooling applications, can be a mini air conditioner for pet or little fridge. Applicable for small space cooling, air cooling dehumidification, semiconductor refrigeration learning theory, etc. Auto-Control: The thermoelectric Peltier refrigeration cooling system kit has temperature controller can be set freely. It will stop automatically when the temperature is high and start automatically when the temperature is high. Energy Saving and Durable: The module semiconductor kit use of more durable refrigeration plate seal can achieve better thermal insulation effect. Description: The semiconductor coolers can be used as a small refrigerator, ice nest and incubator, which has better effect and better heat dissipation effect. It can easily dissipate heat in a few minutes. Notes: Must fitting Heartsink when Power ON,not responsible for Burn Peltier if Heartsink is not Assemble. 12VDC 6A Power is need,but not include in this Kit Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.   Package includes: 1 x Thermoelectric Peltier Refrigeration Cooling System Kit Cooler(finished kit) Package List
