Keep calm on the Move: The Physics behind Car Refrigerator

Think about it. A Car Refrigerator is a device that allows you to take cold drinks or snacks while driving through deserts or camping in the wild. These portable cooling units are increasingly popular with travelers, explorers, and anyone who wants a refreshing drink or some food during a long journey. But how do Car Refrigerator work and what makes them unique?

How Do They Work?
Compressor Technology
Car Refrigerator are based on the use of compressors just as it happens with home refrigerators. The compressor refrigerator used in cars uses a refrigerant that circulates within an enclosed system. When compressed, this fluid gets hot and then cooled as it moves through condenser coils. The heat from inside the fridge is absorbed by the evaporating fluid thereby chilling its content.

Thermoelectric Cooling
Car Refrigerator is thermoelectric cooling in which the Peltier effect comes into play. In this case, the flow of electric current between two dissimilar metals causes one side of them to cool down while making the other hot. Nonetheless, this kind of cooler is less efficient than compressor models though it’s silent and requires minimal maintenance.

Portability and Convenience
The portability aspect has been taken care of properly in Car Refrigerator because they have been made compact hence quite easy to carry along if need be unlike those very big ones at home.. Some models also come with inbuilt castor wheels
