Are Car Refrigerators Really Useful?

[GraceMarie]

Car refrigerators have certain cooling functions. A car refrigerator refers to a portable cooler that can be carried in a car. It has become a popular new generation of cooling and refrigeration appliances in the international market in recent years. Below is relevant information about car refrigerators: 1. Introduction: A car refrigerator refers to a portable cooler that can be carried in a car. It has become a popular new generation of cooling and refrigeration appliances in the international market in recent years. 2. Principle: Car refrigerators are an extension of household refrigerators. They can utilize semiconductor electronic cooling technology or compressor-based refrigeration. They generally produce low noise and minimal pollution. During driving, simply plug the power plug into the cigarette lighter socket to cool the refrigerator. There are mainly two types of car refrigerators on the market: one is the semiconductor car refrigerator, which operates on the principle of electronic chip cooling, using P-N junctions made of special semiconductor materials to form thermocouples and generate the Peltier effect—a new refrigeration method that cools through direct current. The cooling temperature range is between 5 to 65 degrees.
