Porous media heat exchange device and system

Abstract

The invention discloses a porous medium heat exchange device and system, which are used to solve the problem of low efficiency of existing convective heat exchange. The heat exchange device includes: a plurality of sheet heat pipes are arranged at intervals, and porous hydrogen storage is arranged between every two adjacent sheet heat pipes. alloy; each sheet heat pipe is provided with flow holes; the flow holes on adjacent sheet heat pipes are arranged in a staggered manner, and the flow holes of the previous sheet heat pipe correspond to the centers of the multiple flow holes of the next sheet heat pipe, so reciprocating arrangement , the center is a through hole, the circulation hole of each sheet-shaped heat pipe corresponds to a through-hole of the adjacent sheet-shaped heat pipe, and the distance between the circulation hole and the through-hole is the shortest distance in the space. The heat exchange system includes the above-mentioned heat exchange device, and also includes a fan, a second heat pipe connecting the fan and the heat exchange device, and a first heat pipe; the first heat pipe is provided with a medium inlet, and the second heat pipe is provided with a medium outlet; the first heat pipe Both the second heat pipe and the second heat pipe are immersed in the heat-conducting medium, and the medium inlet and the medium outlet are set apart from the heat-conducting medium.

Description

technical field [0001] The invention relates to a porous medium heat exchange device and system, which can be used to solve the problem of low efficiency of existing convective heat exchange, and belongs to the technical field of hydrogenation or dehydrogenation. Background technique [0002] In the prior art, in order to increase the hydrogen storage capacity, the metal alloy hydrogen storage materials used in the hydrogen storage process are mostly in powdery porous form, and the larger the surface area, the greater the hydrogen storage capacity. Heat will be generated during the hydrogen storage process, and the generated heat will lead to an increase in temperature, and the increase in temperature will reduce the hydrogen storage capacity. Therefore, the hydrogen storage process generally uses pressurized and cooled hydrogen to store hydrogen; The heat is used to increase the activation energy of the hydrogen element, so as to get rid of the shackles of the hydrogen stor...
