Problems solved by technology

However, the heat exchange tubes used in this patent are straight tubes, and the influence of the stress caused by thermal expansion and contraction on the sealing performance of the heat exchanger is not considered.
The above-mentioned patents are all applied in high-temperature occasions, and they cannot meet the requirements of anti-pollution and self-relieving stress at the same time.

Abstract

The invention relates to gas low temperature heat exchanger with apontaneous subsiding stress energy pollution prevention. It includes low temperature heat exchanger tunnel body, below end plate, up end plate, A, B, C, and D four tube and shell heat exchangers, tube plate, shoe plate, tube pass inlet pipe and outlet pipe, shell pass inlet pipe and outlet pipe. The shell body of the four tube and shell heat exchangers adopted U shape heat exchanger is narrow rectangle. And the four is set in the low temperature heat exchanger tunnel body and connected each other in series. The low temperature heat exchanger adopts 0Cr18Ni9 / 304 which has little gas permeability, smooth and wear-proof inner surface, strong corrosion resistance, stable performance, and can prevent the air from polluting. In addition, it can remove the stress by itself caused by flatulence due to heat and cold to improve its selling performance. The invention has great economic and social benefits.

Description

technical field [0001] The invention relates to a gas low-temperature heat exchanger, in particular to a gas low-temperature heat exchanger capable of self-relieving stress and preventing pollution. It belongs to the field of cryogenic engineering and cryogenic technology. Background technique [0002] A major project of the Shanghai Municipal Science and Technology Commission: In the research of the Alpha Magnetic Spectrometer 02 (AMS-02) ground support equipment system, the ground support equipment system completed the cooling, testing and superfluid helium filling of the superconducting magnet before the launch of AMS-02 important system. This system will complete the whole process of cooling the AMS-02 superconducting magnet from ambient temperature to 1.8K and filling it with superfluid helium. The 300-80K controlled cooling system is the low-temperature ground support equipment system of the AMS-02 detector. Its main function is to realize the cooling of the AMS-02 m...
