With the continuous development and progress of technology, the quality of life of our people has gradually improved, and car refrigerators have also emerged with the times. Many car owners have already used car refrigerators or are preparing to use them. Why is it so popular with us to become a necessity for a new generation of cars? Now let's understand together.China Car Cooler Box Suppliers
On a hot summer day, car refrigerators have begun to attract people's attention. Car refrigerators of various specifications and models have made the seasons as freely as possible; as a travel necessity widely used in Europe and the United States and other countries-car refrigerators. In China, with the upsurge of self-driving travel, car refrigerators are for car lovers, sending cool breezes, sweeping China... But how much do you really know about car refrigerators? Let me briefly explain below :
At present, there are two main types of car refrigerators on the market, one is a semiconductor heating and cooling box. Its principle is electronic chip cooling, which uses special semiconductor materials to form a PN junction to form a thermocouple pair, which produces a Peltier effect when direct current passes. To achieve cooling and heating, the temperature difference between cold and hot can reach 2-70 degrees. And environmental protection, no fluorine, no pollution, small size, low cost, no vibration noise during operation, low noise, long life and other advantages, but the refrigeration efficiency is not high, and the refrigeration temperature depends on the ambient temperature; the other is traditional vapor compression Onboard compressor refrigerator with built-in refrigeration technology, the refrigeration temperature is low, -18 to 10 degrees, the refrigeration efficiency is high, it can make ice and keep it fresh but it is bulky, it is not convenient to carry, and there is vibration sound when working, the quality stability is poor, only Refrigeration does not heat, and the price is extremely expensive, which is more than 10 times that of the same capacity heating and cooling box, so the compressor car refrigerator has a low cost performance. At present, the car heating and cooling box is the mainstream product on the market.
