Definition of cryogenic liquid cooling system

The cryogenic liquid cooling system is a machine specially used to create low-temperature environments. It can usually control the temperature below -100°C and even reach temperatures almost close to absolute zero.

How does cryogenic liquid cooling system work?

The working principle of cryogenic liquid cooling system is mainly divided into three steps: compression, cooling and expansion.

Compressão

The cryogenic liquid cooling system first compresses the refrigerant into a high-pressure gas through a compressor, thereby increasing its temperature.

Cool down

Then, the high-temperature and high-pressure refrigerant is cooled down through the condenser and becomes a high-pressure liquid, while releasing a large amount of heat.

Expansion

The cooled high-pressure liquid refrigerant then enters the expansion valve (or throttle valve) for expansion. Because the expansion valve is too small, the hydraulic pressure drops sharply, causing the refrigerant to quickly evaporate and take away a large amount of heat, thereby achieving refrigeration.

Application prospects of cryogenic liquid cooling system

Cryogenic liquid cooling systems are widely used in scientific research, industrial production, medicine and other fields.

In terms of scientific research, cryogenic liquid cooling systems can be used to create low-temperature environments and study the properties and behaviors of various materials at extremely low temperatures.

In terms of industrial production, cryogenic liquid cooling systems can be used in electronic manufacturing, high-tech materials, food processing and other industries to improve their production efficiency and product quality.

In the medical field, cryogenic liquid cooling systems are also widely used, such as preserving venomous snake venom, freezing and storing human tissue and plasma, etc.

Key technologies of cryogenic liquid cooling system

The key technologies of cryogenic liquid cooling system lie in three aspects: compressor, heat exchanger and refrigerant.

Compressor

The compressor of the cryogenic liquid cooling system needs to have high strength, high efficiency, corrosion resistance, explosion-proof and other characteristics to meet the needs of the refrigeration system.

Heat Exchanger

The heat exchanger of the cryogenic liquid cooling system needs to have good thermal conductivity and corrosion resistance, and it also needs to be compact and easy to install and maintain.

Refrigerante

The most commonly used refrigerants in cryogenic liquid cooling systems are liquid nitrogen and liquid helium. They have thermal insulation properties at low temperatures, high compressibility and good flow properties, thereby meeting system performance requirements.

In short, cryogenic liquid cooling system is a high-tech refrigeration equipment with extremely high refrigeration capacity and wide application prospects, providing strong support for related industries in scientific research, industrial production and medical fields. The technological innovation and application development of cryogenic liquid cooling system in compressors, heat exchangers, refrigerants, etc. will help promote its development process and promote industrial development and technological innovation.
