Description

Technical Field

[0002] In the prior art, the mobile hydrogen power generation equipment has an internal combustion engine that continues to work during the power generation process, and some heat will be discharged. The entire hydrogen power generation equipment is composed of multiple machines, so it is necessary to transfer the heat in time to avoid long-term erosion of the heat and affect the working machine, thereby improving the safety of the hydrogen power generation equipment and the service life of the machine. The external fan can certainly take away the heat in the power generation equipment, but the many machines in the equipment have complex shapes and are prone to dead corners where heat accumulates. The water-cooling heat dissipation equipment in traditional technology has a low degree of automation and the heat dissipation effect needs to be improved. The water-cooling equipment is built into the box of the hydrogen power generation equipment, and the water-cooling equipment absorbs heat statically by heat transfer. If the water-cooling equipment can deform itself during the heat absorption process, the contact space between the heat and the water-cooling equipment will be increased, and the water-cooling equipment can more quickly absorb heat from the dead corners where heat accumulates.

Multiple heat absorption plate channels 27 swing asynchronously within a certain range, which accelerates the diffusion of heat in the chassis 1 and transfers it to the heat absorption plate channel 27, thereby improving the heat absorption effect of the heat exhaust component 4.
