The vehicle-mounted electronic refrigerator has a simple structure. In order to connect P-type semiconductors, N-type semiconductors, copper plates, and copper wires into a loop, the copper plates and wires only play a conductive role. The loop is powered by 12V DC. After the current is turned on, one contact becomes cold ( inside the refrigerator), and another connector dissipates heat (the radiator behind the refrigerator).

    This refrigerator has a simple structure, few parts, and is easy to maintain: no mechanical transmission parts, no wear, no noise, long life: no refrigerant refrigeration (both compression and absorption types are required), and it is absolutely environmentally friendly.

    Now there are energy storage board cooling passive car refrigerators on the market that do not consume electricity, and of course, they will not dissipate heat in the car, reducing the heat source in the car. Before use, you only need to put the ice bag in the refrigerator into the household refrigerator to fully freeze, and then put the ice bag into the car refrigerator for cooling. This passive refrigerator avoids the noise generated when the compressor is working, but the energy storage board Refrigeration passive vehicle-mounted refrigerators must be placed in the refrigerator freezer to freeze and charge the energy storage board before use, so it cannot be left out of the refrigerator for too long, and it is not very convenient to use.

    At present, two types of vehicle-mounted refrigerators, refrigerated and refrigerated, have been launched in China according to market demand. Customers can purchase passive mobile refrigerators with both freezing and refrigerating functions by purchasing different energy storage.
