Embodiment 1

[0028] like figure 1 As shown, a cooling system for a hydrogen fuel cell forklift truck includes a radiator 3 and an expansion water tank 4 installed and fixed at the rear of the forklift truck. The radiator 3 is connected with two water pipes 5 for entering and leaving water respectively, one of the water pipes 5 is used for connecting with the hydrogen fuel cell 1 installed on the hydrogen fuel cell 1 forklift, and the other water pipe 5 is connected with the water pump 2 . Correspondingly, a water pipe 5 is connected between the water pump 2 and the hydrogen fuel cell 1 . At the same time, an exhaust pipe 6 is connected between the water pump 2 and the expansion water tank 4 and between the radiator 3 and the expansion water tank 4 , and a water supply pipe 75 is connected between the expansion water tank 4 and the water pump 2 . Among them, the cooling water tank 31 is used to store the cooling liquid, and the water pump 2 plays the role of providing the power to drive th...

Embodiment 2

[0033] The difference between the second embodiment and the first embodiment is that the rear end of the cooling fan 32 in the second embodiment is provided with a wind deflector. The air guide plate is used to guide the airflow of the cooling fan 32 to the air outlet.

[0034]To sum up, the present application provides a cooling system for a hydrogen fuel cell forklift truck. The hydrogen fuel cell forklift cooling system places the radiator 3 and the expansion water tank 4 at the rear of the forklift, so that the arrangement environment of the radiator 3 and the expansion water tank 4 is improved. The temperature is significantly lower than the internal ambient temperature of the hydrogen fuel cell 1, thereby significantly improving the heat dissipation performance of the hydrogen fuel cell forklift cooling system, so that the life and working efficiency of the hydrogen fuel cell 1 are effectively improved. At the same time, by optimizing the structure of the air outlet, the...

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.
