Background Art

A fuel cell is a power generation device that converts the chemical energy in fuel and oxidant directly into electrical energy. Fuel and air are separately fed into the fuel cell, and electricity is miraculously produced.

Prior art CN217280869U is an integrated device for fuel cell heat dissipation, which is arranged on the roof of a bus, located on the left and right sides and rear side of the escape compartment door. Radiator 1 and radiator 2 are of a four-fan structure with left-right symmetry. Radiator 1 is located on the left side and radiator 2 is located on the right side. The upper planes of radiator 1 and radiator 2 are inclined at an angle of 174°, which is used to reduce the height dimensions of the overall structure on both sides. In order to minimize the design of the device, all steel pipes and silicone tubes are arranged on the rear side of radiator 1 and radiator 2, and are arranged in multiple layers staggered up and down. For easy fixation, all pipeline connections are fixed by the middle steel pipe and connected by silicone tubes at both ends. The end of each silicone tube is connected to the corresponding connecting pipe openings of radiator 1, radiator 2 and expansion water tank, which maximizes the use of the layout space on the roof and optimizes the layout space of the entire device structure.

The integrated device for heat dissipation of fuel cells in the prior art has poor heat dissipation effect at the bottom of the fuel cell. The heat at the bottom of the fuel cell is not easy to dissipate and will gradually accumulate between the fuel cell and the shell. Over time, the fuel cell will overheat and be damaged, thereby reducing the service life of the fuel cell.
