Embodiment 1

[0035] Embodiment 1 is basically as attached figure 1 and figure 2 Shown:

[0036] A solid-state hydrogen storage device with high heat exchange characteristics, comprising an outer tank 1, figure 1 The middle and outer tanks 1 are placed horizontally, the left end of which is the bottom of the outer tank 1, and the right end is the top of the outer tank 1. The hydrogen storage device is placed vertically when in use, and an air inlet and outlet valve 2 is provided at the right end of the outer tank 1, wherein the outer tank 1 The tank 1 is made of aluminum alloy, carbon steel or stainless steel, with a thickness of 2-5 mm, a length of 200-300 mm, and an outer diameter of 50-80 mm.

[0037] 4 to 10 hydrogen storage cylinders 3 are fixed inside the outer tank 1. In this embodiment, there are 4 hydrogen storage cylinders 3, and the four hydrogen storage cylinders 3 are connected sequentially from left to right, and the central axis of each hydrogen storage cylinder 3 is in li...

Embodiment 2

[0041] Embodiment 2 is basically as Figure 4 Shown:

[0042] The difference between Embodiment 2 and Embodiment 1 is that a sleeve 12 is provided outside the outer tank 1, and a plurality of heat transfer fins 11 are integrally formed on the outer wall of the sleeve 12. The heat transfer fins 11 are evenly distributed along the axial direction of the sleeve 12, the thickness of the heat transfer fins 11 is 0.5-3mm, the heat transfer fins 11 are made of aluminum alloy, and the outer wall of the outer tank 1 is coated with heat-conducting glue, The sleeve 12 is bonded on the outer tank 1 by heat-conducting glue.

Abstract

The invention relates to the technical field of hydrogen storage equipment, and specifically discloses a solid-state hydrogen storage device with high heat exchange characteristics, including an outer tank, the top of the outer tank is provided with an inlet and outlet valve, and several hydrogen storage devices are sequentially fixed inside the outer tank There is a gap of 0.5-3mm between adjacent hydrogen storage cylinders. Filters are fixed at both ends of the hydrogen storage cylinders. A number of heat-conducting partitions are arranged inside the hydrogen storage cylinder along its axial direction. It is divided into multiple hydrogen storage spaces, and hydrogen storage materials are installed in the hydrogen storage spaces. The invention adopts multi-layer storage space, which can realize faster hydrogen absorption, and effectively solves the problems of uneven distribution of hydrogen storage materials in the hydrogen storage tank and structural damage caused by stress concentration in the prior art; in addition, hydrogen storage materials The uniform distribution of the hydrogen absorption process makes the heat distribution more uniform, and the heat can be conducted out of the hydrogen storage device more quickly.

Description

technical field [0001] The invention relates to the technical field of hydrogen storage equipment, in particular to a solid-state hydrogen storage device with high heat exchange characteristics. Background technique [0002] With the progress of modern society and the development of economy, the demand for energy is increasing day by day. The traditional fossil energy represented by oil, coal and natural gas belongs to non-renewable energy and is facing the plight of gradual depletion. Hydrogen energy has attracted extensive attention from researchers and investors around the world because of its high combustion calorific value, zero emissions, and its ability to be used as a high-density energy storage carrier. [0003] There are three main ways to store hydrogen: high-pressure gaseous hydrogen storage, liquid hydrogen storage, and solid-state hydrogen storage. The main disadvantage of high-pressure gaseous hydrogen storage is that the hydrogen storage density is small, an...
