The water storage tank 5 has a plurality of planetary fins 52 on its outer wall, which greatly increase the heat dissipation area. The high-temperature cooling liquid is cooled in the water storage tank 5 by exchanging heat with the outside air through the planetary fins 52. If it is used indoors, an air blower can be additionally configured to assist in heat dissipation. This circulation process ensures that the reaction kettle 1 can be continuously cooled, thereby maintaining the efficient operation of the hydrogen production process. Thus, the device completes its work.
