What are they made of?
Car refrigerators are made of high-strength plastic in different colors. Plastic, I must say, is really durable. During one presentation, the largest person from among the invited guests was asked to stand up on a small refrigerator, and then jump a little. According to the guest, he weighed about 100 kg. And the refrigerator “for this” was nothing.
A nice feature of car refrigerators is that they are very convenient to wash, you can just use water or any non-aggressive plastic cleaner.
The main feature of car refrigerators is that they work on the principle of the Peltier effect (thermoelectricity) and there is no compressor or freon in their design. The space between the walls is filled with polyurethane foam with a thickness of 3 to 5 cm. The insulation ensures long-term preservation of the low temperature even after the refrigerator is turned off.
Almost all models are equipped with a built-in fan, which provides a fast and constant cooling effect. The system provides a temperature drop by 20-24 ° C below the ambient temperature. And it does not require any special care. Some models of car refrigerators not only cool, but also allow you to keep already cooked food hot.
