Description

Technical Field

[0001] The utility model relates to the field of hydrogen fuel cells, and more specifically, to a heat dissipation device for a hydrogen fuel cell. Background Art

[0002] Hydrogen fuel cells generate electricity and water after electrochemical reactions, and also generate a large amount of heat energy. The electrochemical reaction of hydrogen fuel cells needs to be carried out at a suitable temperature. If the temperature is too high, it will affect the use of hydrogen fuel cells. Therefore, the hydrogen fuel cell group needs to dissipate the heat generated by the hydrogen fuel cell during operation to ensure the normal use of the hydrogen fuel cell. To address this problem, the existing hydrogen fuel cells use air cooling or liquid cooling to cool down the battery when performing heat dissipation treatment. When using air cooling treatment, the existing heat dissipation structure mostly uses the air duct mechanism to directly guide the battery to take away the heat. The problem is that the airflow needs to be continuously transported by the air duct mechanism, and it is immediately dispersed to the surroundings when it contacts the battery, which is more energy-consuming and has a low actual heat dissipation effect. When liquid cooling is used for heat dissipation, the liquid cooling mechanism is difficult to effectively contact the battery structure for direct heat dissipation and cooling, so fins or heat-conducting structures are needed to assist it, which leads to a complex overall structure, high cost, time-consuming and labor-intensive maintenance and replacement, and low convenience of use.

[0003] Therefore, the utility model proposes a hydrogen fuel cell heat dissipation device. Utility Model Content
