There are roughly three types of car refrigerators, incubators, semiconductor car refrigerators, and compressor car refrigerators.
Incubator: It does not have a cooling function, only the insulation function needs to be put into an ice pack when refrigerating things. It is a relatively early product, the advantage is that it does not consume electricity, and the disadvantage is that it cannot be kept warm for a long time, and the space is small.
Semiconductor car refrigerator: It relies on electronic chips for refrigeration. The advantages are that it can both cool and heat, environmental protection, no pollution, small size, low cost, no vibration, noise, and long life during operation. The disadvantage is that the refrigeration efficiency is not high and the capacity is small.
Compressor Car Refrigerator: Compressor is the traditional technology of traditional refrigerators, and the cooling temperature is low, which is -18 degrees 10 degrees. Its advantages are high refrigeration efficiency and large volume, which is the mainstream direction of the future development of car refrigerators. The disadvantage is that the weight is heavier, the power consumption is relatively high, and the price is higher.
