Abstract
The application relates to the technical field of fuel cells, and discloses a fuel cell heat dissipation system, a control method and a fuel cell. The fuel cell heat dissipation system can utilize high-temperature cooling liquid discharged from an electric pile to heat the gas-water mixture discharged from the exhaust port of the electric pile while air cooling is performed on a heat dissipation assembly by a heat dissipation fan, the heated gas-water mixture is sent to a heat dissipation spraying unit by a drainage fan, the gas-water mixture is atomized to form water mist and is sprayed to the surface of the heat dissipation assembly, the water mist absorbs the heat emitted by the heat dissipation assembly, the heat dissipation fan strengthens the air circulation around the heat dissipation assembly, the water mist is evaporated to take away the heat of the heat dissipation assembly, and the heat dissipation effect of the heat dissipation assembly is improved. The gas-water mixture discharged from the exhaust port of the electric pile is heated by the high-temperature cooling liquid discharged from the electric pile to form high-temperature gas-water mixture, the temperature of the water mist formed by atomization is high, the water mist is more easily evaporated after absorbing the heat on the surface of the heat dissipation assembly, and the liquid water mist is prevented from gathering on the surface of the heat dissipation assembly, so that the heat dissipation effect on the heat dissipation assembly is improved.
