Mini Refrigerated Compressor Vapor Compression Cooling

RIGID specializes in a miniature cooling technique called vapor compression. Vapor compression cooling makes use of the unique characteristics of refrigerants to pump heat from a low temperature to a high temperature through the use of refrigerants. Systems that use vapor compression use the thermodynamics of refrigerants to cool components. Heat is absorbed from its source and is redirected to an external environment that's warmer (usually the ambient environment).

As an active thermal management method, vapor compression cooling systems produce sub-ambient cooling. Vapor compression refrigeration systems are highly efficient ways to perform active thermal management by using appropriate refrigerants, compressors, and heat exchangers.

RIGID’s miniature compressor vapor compression units have been successfully applied to many electronics and medical devices. RIGID compact water chillers are used to cool electronics mounted inside customer's systems. RIGID miniature chillers are 5 times lighter, 4 times more energy efficient, and half the size of thermoelectric based systems.

If that seems interesting and you’d like to know more about RIGID’s products, you are in the right place. Here is a short overview of the compression cooling and miniature circulating cooling systems for active thermal management. Check out different solutions, and don’t hesitate to contact us if you have any questions!
