Hydrogen fuel cell forklift cooling system

Abstract

The invention discloses a hydrogen fuel cell forklift truck cooling system, which relates to the technical field of battery cooling and comprises a radiator and an expansion water tank which are fixedly mounted at the rear part of a forklift truck, the radiator is connected with two water pipes which are respectively used for water inlet and water outlet, one water pipe is used for being connected with the hydrogen fuel cell, the other water pipe is connected with a water pump, and a water pipe is connected between the water pump and the hydrogen fuel cell; exhaust pipes are connected between the water pump and the expansion water tank as well as between the radiator and the expansion water tank, and a water supplementing pipe is connected between the expansion water tank and the water pump. The radiator and the expansion water tank are placed at the rear part of the forklift, so that the arrangement environment temperature of the radiator and the expansion water tank is obviously lower than the internal environment temperature of the hydrogen fuel cell, and the heat dissipation performance of the hydrogen fuel cell forklift cooling system is obviously improved; and the service life and the working efficiency of the hydrogen fuel cell are effectively improved.
