Description

A high-efficiency heat dissipation device for fuel cell

Technical Field

The utility model relates to the field of heat dissipation devices, in particular to a high-efficiency heat dissipation device for a fuel cell.

Background technique

A fuel cell is a device that converts chemical energy directly into electrical energy, and it generates heat during operation. In order to ensure efficient operation and extend the life of the fuel cell, an efficient heat dissipation device is required to effectively dissipate the heat. An efficient heat dissipation device can effectively reduce the operating temperature of the fuel cell, keep it operating within a suitable temperature range, and improve the efficiency and life of the fuel cell. However, since the fuel cell works continuously and continuously conducts chemical reactions to output electrical energy, accompanied by a large amount of heat release, the temperature of the fuel cell quickly exceeds this temperature, and the stability and proton conductivity of the battery decrease, resulting in unstable output power of the fuel cell, which seriously affects the life of the battery and may even cause major safety issues.

However, some existing fuel cell heat dissipation devices use fans for heat dissipation. The fans blow air to the fuel cell to speed up the air circulation in the space where the fuel cell is located, thereby taking away the heat generated by the fuel cell and achieving the purpose of heat dissipation and cooling the fuel cell. However, the space is limited and the heat dissipation method is relatively simple. When there is a problem with the fan, the fuel cell will become overheated, which will eventually affect the life of the battery.

Therefore, those skilled in the art provide a high-efficiency heat dissipation device for a fuel cell to solve the problems raised in the above background technology.
