Cryogenic technology is a field that involves the handling of substances and operating systems at very low temperatures. It is mainly about the technology of acquiring, maintaining and applying low temperatures. According to the different temperature ranges, cryogenic technology can be divided into general cooling technology and cryogenic technology, in which the scope of general cooling technology research is in the general cooling area, and the scope of cryogenic technology research is in the cryogenic area, which is based on the temperature of 120K (about -153.15 °C) as the dividing line.
Cryogenic technology has a wide range of applications in many fields, including but not limited to the following:
Preparation of superconducting materials: Superconducting materials exhibit impedance-free current transmission characteristics at low temperatures, and can be widely used in power transmission, electronic communications, computers, medical technology and other fields.
Medical diagnosis and treatment: Cryogenic technology also plays a very important role in the medical field, such as cryotherapy for dermatological diseases, ophthalmic diseases, etc., as well as cryopreservation of biological samples and organs.
Refrigerated transportation: In the fields of medicine, oncology, immunology and biological products, cryogenic transportation technology is of great significance.
Scientific research: Cryogenic technology provides an important experimental environment for scientific research, such as particle physics, condensed matter physics, etc.
In addition, cryogenic technology is widely used in industries such as food, semiconductors, and chemicals to preserve food, manufacture electronic components, and perform chemical reactions.
The development trend of low-temperature refrigeration technology is diversification, high efficiency and intelligence. With the increasing demand for refrigeration technology in various industries, cryogenic refrigeration technology will provide more comprehensive and in-depth solutions for more fields. At the same time, with the improvement of environmental awareness, low-temperature refrigeration technology will also pay more attention to energy conservation and environmental protection to achieve sustainable development.
For a more in-depth understanding of the definition, application, and development trend of cryogenic technology, it is recommended to consult professional books or literature in the fields of physics, materials science, chemical engineering, etc.
