There are not many things that often need to be kept fresh and high-quality. Using a small refrigerator can save the next expensive electricity bill! You can also store night drinks in the bedroom and connect with a 220-volt public standard wire. You can put the mini car freezer in the corner of the room, which saves power and space, and is convenient and practical.
The semiconductor refrigerator in the mini car refrigerator is also called an electronic refrigerator, which is different from other refrigerator products that use compressors. The electronic semiconductor car refrigerator uses a PN junction composed of special semiconductor materials to form a thermocouple pair. A small semiconductor chip uses the Peltier principle. In a circuit composed of two different conductors, the DC circuit passes through the junction The metal sheet joints release heat, and realize the ultimate goal of cooling and heating through different current flows. Thanks to this cooling method, the electronic semiconductor-type vehicle-mounted heating and cooling box can be used for cooling and heating, and the operating temperature ranges from 5 to 65°C.
