Description

technical field [0001] The invention relates to refrigeration, in particular to a refrigeration device and a maintenance method thereof. Background technique [0002] In photoelectric analysis technology, in order to improve the working performance of the detector, the detector needs to be refrigerated, and liquid nitrogen refrigeration is a common cooling method. However, as the working hours increase, cooling fluids such as liquid nitrogen need to be perfused. [0003] At present, manual perfusion of liquid nitrogen is mostly used, but this may burn the operator, threaten the health of the operator, take a long time, and also waste liquid nitrogen, which increases the cost. Contents of the invention [0004] In order to solve the shortcomings in the above-mentioned prior art solutions, the present invention provides a refrigeration device that is safe, automatic, cost-saving and improves the working performance of the detector. [0005] The purpose of the present inven...
