Refrigeration device and its maintenance method

Abstract

The invention provides a refrigeration device and a maintenance method thereof. The refrigeration device comprises a first container, a pipeline, a switch module, a second container, a third container and a temperature sensor, wherein a pressurizing module is arranged on the first container, fluid for refrigeration is contained in the first container, the pipeline is used for being communicated with the outlet end of the first container and the inlet end of the second container, the switch module is arranged on the pipeline, the outlet end of the second container is communicated with the inlet end of the third container, a detector is arranged on the third container, and the temperature sensor is arranged in the third container and suspended. The refrigeration device has the advantages of being safe and automatic, achieving unattended operation, saving cost and the like.

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...
