Thermoelectric Peltier Cooling System Set

Description: Semiconductor coolers are a form of solid state cooling that incorporates both semiconductor Technologies and electronic assembly techniques. Precautions: 1. The hot end of the cooling fin must be well dissipated. If the heat conduction silicone grease is applied well, if the heat dissipation is not good, not only the temperature will not be too low, but also the cooling fin will be easily burnt out. Definitely burned inside)! 2. It cannot be used as an air conditioner, you must understand the law of conservation of energy! 3. The refrigeration fins can't be installed backwards, the small conductive block is too small, and the heat dissipation is not enough! ! !
