A heat transfer method based on the heat transfer structure of a full-layer steel high-pressure hydrogen storage vessel

Abstract

The invention belongs to the field of hydrogen energy, and relates to a heat exchange structure and a heat exchange method of an all-multilayer steel high-pressure hydrogen storage container. Including protective shell, fuel tank and jacket; the protective shell is a sleeve structure, which is set in the middle of the full-layer steel high-pressure hydrogen storage container, and the protective shell is the steel belt layer of the full-layer steel high-pressure hydrogen storage container, and the protective shell There is a heat-conducting medium in the gap with the steel belt layer; there are two saddles on both sides of the bottom of the protective shell, which are used to support the full-layer steel high-pressure hydrogen storage container and heat exchange structure; the medium inlet joint of the protective shell and the protective shell The medium outlet joints are welded on the left and right ends of the protective shell respectively. The medium inlet joint of the protective shell is used to connect the oil pool, and the medium outlet joint of the protective shell is connected to the oil tank and the vacuum pump. There is a jacket medium inlet and outlet on the sleeve. The invention can realize the internal and external heat exchange of the full-layer steel high-pressure hydrogen storage container, and the operation is simple and convenient.

Description

technical field [0001] The invention belongs to the field of hydrogen energy, and relates to a heat exchange structure and a heat exchange method of an all-multilayer steel high-pressure hydrogen storage container. Background technique [0002] Hydrogen energy has the advantages of high calorific value, diverse sources, clean and environmentally friendly, and efficient utilization. It is an important development direction of future energy. Vigorously developing hydrogen energy is an important measure for my country to transform its energy consumption structure, ensure energy security, alleviate air pollution, reduce greenhouse gas emissions, and maintain sustainable economic development. [0003] The full-layer steel high-pressure hydrogen storage container is a product independently developed and designed by my country. It has the advantages of adapting to high-parameter design, explosion suppression and anti-explosion, defect dispersion, online monitoring of health status,...

AI Technical Summary

Problems solved by technology

Due to the high hydrogen storage pressure of the full-layer steel high-pressure hydrogen storage container, the wall thickness of the container is large, and it is a full-layer structure, a heat exchange jacket is directly installed outside the container, which will make heat transfer difficult.

In addition, in order to ensure the tightness of the container, the aperture at the end of the container is very small, only for hydrogen to enter and exit, and cannot provide an inlet and outlet channel for internal heat exchange

In view of the particularity of the container structure, there is no ready-made heat exchange structure and method at home and abroad.
