What Is A Car Refrigerator? 

What is a car refrigerator? Is there any use?

The car refrigerator is a mobile refrigerator used in the car, which has the advantages of low power consumption, less pollution, and low noise. On the way of driving, connect the power supply to the cigarette hole, and the on-board refrigerator can be cooled by the electricity generated by the engine. Compressor-cooled refrigerators can usually freeze below 0°C.

The function of the car refrigerator is very simple, providing the function of mobile refrigeration in the car. And the power consumption and noise are very low, and will not bring a burden to the car. Moreover, most car owners prefer to have a mobile freezer in the car, and they can take out fresh and cold drinks and fruits at any time to satisfy their appetites.

What types of car refrigerators are there?

At present, there are mainly two car refrigerators with different refrigeration methods, one is the electronic semiconductor car refrigerator. Its principle is to perform cold and heat conversion through electronic semiconductor chips, and use the P-N junction of semiconductor materials to form thermocouple pairs to produce Peltier effect; the temperature range of working refrigeration is 5 to 65 °C.

The advantages of this kind of refrigerator are that it can be cooled and heated, with small size, low power consumption and low cost; no noise during operation; the disadvantage is that the refrigeration efficiency is not high, and it cannot freeze, and the capacity is relatively small.

The other is the compressor car refrigerator, which is also the current mainstream car refrigerator; the compressor is a traditional refrigeration technology, with high refrigeration efficiency, and the refrigeration temperature can be from -18 to 10 ℃, this car refrigerator can freeze and freeze It is also the mainstream direction for the development of car refrigerators in the future.

The advantage of the compressor car refrigerator is that it has strong cooling and heat preservation functions, but it is relatively heavy and expensive.
