Water-cooling heat dissipation structure

The utility model provides a water-cooling heat dissipation structure, which relates to the technical field of hydrogen fuel cell heat dissipation, and comprises a fuel cell body, a hydrogen storage device is arranged on one side of the fuel cell body, a heat conduction pipe is arranged on the outer side of the hydrogen storage device, and the heat conduction pipe is connected with the fuel cell body. Two ends of the heat conduction pipe are respectively connected with a cooling pipe and a cooling device in the fuel cell body, and the hydrogen storage device is a hydrogen storage tank; heat generated in the fuel cell body is brought out through the cooling pipe in the fuel cell body and the cooling liquid in the pipe, the cooling liquid containing the heat firstly makes contact with the hydrogen storage device, a part of the heat is absorbed through the hydrogen storage device releasing hydrogen, the temperature of the cooling liquid is reduced to a certain extent, and then the cooling liquid is cooled to a c
