How Does a Car Refrigerator Work?

[Clayton]

Semiconductor car refrigerators operate based on electronic chip cooling, utilizing P-N junctions formed by special semiconductor materials to create thermocouple pairs, which generate the Peltier effect—a novel refrigeration method that cools through direct current, with a cooling temperature range of 5 to 65 degrees. Compressor car refrigerators use traditional compressor technology, offering lower cooling temperatures, typically between -18 to 10 degrees. Below is additional information about car refrigerators: 1. Car refrigerator: refers to a portable cooling cabinet that can be carried in a car. Car refrigerators have become a popular new generation of cooling and refrigeration appliances in the international market in recent years. 2. Semiconductor car refrigerator: Also known as an electronic refrigerator, semiconductor car refrigerators differ from traditional refrigerators that use refrigerants for cooling. The principle of semiconductor car refrigerators falls under electronic physical cooling. This cooling method utilizes the "Peltier Effect."
