Description

Technical field [0001] The present invention relates to refrigeration, in particular to refrigeration devices and maintenance methods thereof. Background technique [0002] In the photoelectric analysis technology, in order to improve the working performance of the detector, it is necessary to refrigerate the detector, and liquid nitrogen refrigeration is a long-term refrigeration method. However, as working hours increase, cooling fluids such as liquid nitrogen need to be injected. [0003] At present, manual liquid nitrogen infusion is mostly used, but doing so may scald the operator, threaten the health of the operator, and take a long time. At the same time, it also wastes liquid nitrogen and increases costs. Summary of the invention [0004] In order to solve the above-mentioned deficiencies in the prior art solutions, the present invention provides a refrigeration device that is safe, automated, saves costs, and improves the performance of the detector. [0005] The purpose of...
