Function and Application of Cryogenic Device

A cryogenic device is a device that uses a refrigerant to deeply cool an object. The cryogenic device can reduce the temperature of the object to the required low temperature to meet specific needs. Cryogenic devices are used in many different fields, such as pharmaceuticals, chemicals, aerospace, military, etc. This article will introduce the function, principle, structure and application of cryogenic device. 1. role The main function of the cryogenic device is to reduce the temperature of the object to the required low temperature to meet specific needs. Cryogenic devices can be used in the following areas: Pharmaceutical field: The cryogenic device can be used to freeze pharmaceutical raw materials, drugs, biochemical products, etc., making it easier to store and transport. Chemical industry: cryogenic devices can be used to cool chemical reagents, catalysts, coatings, etc., to reduce their reaction speed and extend their service life. Aerospace field: Cryogenic devices can be used to manufacture cryogenic media such as liquid oxygen and liquid hydrogen in aerospace equipment. Military field: cryogenic devices can be used to manufacture high-energy lasers, ballistic missiles and other military equipment. 2. principle The working principle of the cryogenic device is to use the cycle of the refrigerant to reduce the temperature of the object to the required low temperature. Specifically, the cryogenic device includes components such as a compressor, a condenser, an expansion valve, an evaporator, and a pipeline. A refrigerant circulates between these sections, thereby lowering the temperature of the object to a desired low temperature. 3. structure The structure of the cryogenic device includes compressor, condenser, expansion valve, evaporator, pipeline, controller and other components. Among them, the compressor is used to compress the refrigerant into high-pressure gas, the condenser is used to cool the high-pressure gas into high-pressure liquid, the expansion valve is used to expand the high-pressure liquid into low-pressure liquid, and the evaporator is used to evaporate the low-pressure liquid into low-temperature vapor. The pipeline is used to connect the various components, and the controller is used to control parameters such as temperature and pressure.
