Incubator: the shell is made of thermal insulation materials, and the temperature of the goods is maintained after the energy storage box is used for refrigeration and heating. Incubator car refrigerator is a relatively early product. It may not be suitable to call it refrigerator because it has no refrigeration function, only heat preservation function. When it is used, it is necessary to put the items to be refrigerated in the refrigerator and put them into the incubator after freezing. If there is an ice bag, put it into the ice bag. In this way, it can keep frozen in a short time. The advantage of this kind of refrigerator is that it does not consume electricity, You know, the electricity on the car is oil, and the price is relatively low. The disadvantage is that it can't keep warm for a long time, and the space is small.
Electronic refrigeration refrigerator - also known as semiconductor car refrigerator: with advanced semiconductor technology, electronic refrigeration and heating are realized. The refrigeration is 5-10 degrees and the heating is 65 degrees. The principle of semiconductor car refrigerator is to rely on electronic chips for refrigeration. The p-n junction made of special semiconductor materials is used to form thermocouple pairs and produce Peltier effect, which is a new refrigeration method through direct current refrigeration. The refrigeration temperature range is 5 to 65 degrees. The car refrigerator can not only refrigerate, but also heat and keep warm. It has incomparable advantages over conventional refrigerators. The main advantages are: environmental protection, low cost, low cost and low cost No pollution, small size, low cost, no vibration, noise, long life. The disadvantages are low refrigeration efficiency and small capacity.
Compressor vehicle refrigerator: relying on the imported advanced spherical compressor and frequency converter, it uses 12V DC power supply to achieve refrigeration. The refrigeration temperature is - 18 degrees, and the price is more than 4000 yuan. It is suitable for customers with special requirements. Compressor car refrigerator, compressor is the traditional technology of traditional refrigerator, refrigeration temperature is low, for - 18 degrees 10 degrees. With high refrigeration efficiency and large volume, it is the mainstream direction of the development of vehicle refrigerators in the future. The disadvantages are heavy weight, power consumption and high price. The compressor of automobile refrigerator is mainly produced in Germany and Japan in the world. The compressor of domestic high-grade compressor automobile refrigerator is mainly produced in Germany with good quality.
