FAQ
What Is A Cryo Cooler And How Does It Work?
A cryo cooler is a device used to reach extremely low temperatures for cooling purposes, usually below -150 degrees Celsius. It works on the principle of gas compression and expansion to remove heat from an enclosed space. The process starts with the compression of a gas, typically helium, which increases its temperature and pressure. The gas is then expanded through a valve, causing it to cool rapidly due to the Joule-Thomson effect. This cooled gas is then circulated to absorb heat from the target area, allowing for effective cooling to very low temperatures.
What Are The Key Components Of A Cryo Cooler?
A cryocooler typically consists of four key components: a compressor, a cold head, a heat exchanger, and a thermal expansion valve. The compressor is responsible for compressing and circulating the refrigerant gas.
