Car refrigerators – products that most riders have considered but have not purchased.
Why? ——High price/bulk size/small volume/unsatisfactory cooling effect/low frequency of use/less use of scenes, etc. can all be the reason for not buying.
What is the reason for the purchase? Have! On a hot summer day, on the road to the dead dog, enjoy the frozen cola and icy fruit in the car on the way of self-driving tour.
3, compressor type car refrigerator
This kind of can be described as high and handsome in the car refrigerator, the price is generally more than $200, the cooling temperature can reach minus 18 degrees Celsius.
However, in addition to the expensive goods, there is a disadvantage that the volume is large and the volume is small enough.
2, semiconductor car refrigerator
Its principle is to rely on electronic chip refrigeration, using a PN junction composed of special semiconductor materials to form a thermocouple pair, resulting in a Peltier effect, a new refrigeration method through DC cooling, the refrigeration temperature range is -5 to 65 degrees. In actual use, it is affected by the external temperature, and it can be 4 degrees Celsius. It is very good, and the cooling speed is very slow. It is generally used for refrigeration. Moreover, there is still the disadvantage of having a large volume and a small volume.
Strictly speaking, the incubator is not a “car refrigerator” at all. However, from the practical point of view, as long as it is used properly, it can also play the role of a car refrigerator. A good incubator, the price is not lower than the semiconductor refrigerator.
