thermoelectric cooler 200W 48V

Thermoelectric is a cooling and heating mode. Semiconductor refrigeration is also called electronic refrigeration, or thermoelectric refrigeration. It uses special semiconductors to produce Peltier effect, that is, through the P-N junction composed of straight materials, thermocouple pairs are formed to generate Peltier Effect and compression refrigeration and absorption refrigeration are a new type of refrigeration method called galvanic refrigeration
