Abstract

The invention provides an inner side wall structure of a vertical low-temperature container and the vertical low-temperature container, wherein the inner side wall structure of the vertical low-temperature container comprises a metal corrugated pipe expansion joint, wherein a first end of the metal corrugated pipe expansion joint is fixedly connected with a room temperature end of the inner side wall of the vertical low-temperature container; a second end of the metal corrugated pipe expansion joint is fixedly connected with the low-temperature end of the inner side wall of the vertical low-temperature container. The side wall thickness of a neck pipe of the vertical low-temperature container is reduced through the metal corrugated pipe expansion joint; meanwhile, the conduction path is increased, so that the heat leakage along the neck pipe side wall is reduced.

Description

technical field [0001] The invention relates to the technical field of cryogenic containers, in particular to an inner wall structure of a vertical cryogenic container and the vertical cryogenic container. Background technique [0002] Cryogenic container is a device used to hold low-temperature media (such as liquid nitrogen, liquid oxygen, liquid helium, etc.). The French scientist Dewar first proposed a container with a double-wall structure in 1892, which achieved better heat preservation. Effect. The current cryogenic containers basically adopt this double-wall structure, so the cryogenic containers are also commonly referred to as "Dewars". Heat leakage is one of the most important technical indicators in the design of cryogenic containers. Its purpose is to minimize the volatilization of the cryogenic medium in the cryogenic container due to heat absorption. [0003] The heat leakage of the cryogenic vessel is mainly composed of three parts: the simplified body (mul...
