[0025] like Figure 1-Figure 4 As shown, a hydrogen fuel cell cooling system includes a radiator, a hydrogen fuel cell 3 and an expansion water tank 8;

[0026] The hydrogen fuel cell 3 is provided with a degassing port 4, a water outlet 5, a water inlet 7 and a water supply port 6. The water outlet 5 is connected to the radiator through a cooling water outlet pipe 11, and the water inlet 7 is connected to the radiator through a cooling water inlet pipe 10, thereby dissipating heat from the hydrogen fuel cell 3 through the radiator.

[0027] The expansion water tank 8 is connected to the water supply port 6 of the hydrogen fuel cell 3 via a water supply pipe 12 , and a degassing pipe 13 is provided between the expansion water tank 8 and the degassing port 4 of the hydrogen fuel cell 3 .

[0028] In some embodiments, as Figure 1-Figure 3 As shown, the radiator includes a radiator 1 9 and a radiator 2 16 arranged in parallel. Both the radiator 1 9 and the radiator 2 16 are equipped with 6 electronic fans to ensure sufficient heat dissipation capacity.

[0029] In some embodiments, as Figure 1-Figure 3 As shown, a degassing pipeline 2 14 is connected between the expansion water tank 8 and radiator 1 9, and a degassing pipeline 3 15 is connected between the expansion water tank 8 and radiator 2 16. Through the degassing pipelines 2 and 3, the gas in the coolant flowing into the radiator is introduced into the expansion water tank 8 and discharged from the system through the pressure cap of the expansion water tank 8.

[0030] In some embodiments, as Figure 1 As shown, a temperature sensor 17 is installed on the cooling water outlet pipe 11, and a temperature sensor 17 and a conductivity meter 18 are installed on the cooling water inlet pipe 10. The two temperature sensors 17 can monitor the temperature of the coolant flowing into and out of the hydrogen fuel cell 3 in real time to ensure that the hydrogen fuel cell 3 operates at a suitable temperature; the conductivity meter 18 can monitor the ion concentration of the coolant flowing into the hydrogen fuel cell 3 in real time to ensure that the insulation resistance of the entire fuel cell system is within a safe range.

[0031] In some embodiments, as Figure 1 As shown, a deionizer 19 is installed on the degassing pipeline 13, and the deionizer 19 is connected in series in the degassing pipeline 13 to adsorb ions in the coolant.

[0032] In some embodiments, as Figure 4 As shown, the radiator and expansion water tank 8 are respectively installed on the rear side of the hydrogen cylinder frame assembly 1, which solves the problem of chassis space limiting the radiator size. The radiator is located at the bottom and the expansion water tank 8 is located at the top, which can absorb and compensate for the coolant and water vapor when the cooling system is working, assist the cooling system to complete heat dissipation, prevent the hydrogen fuel cell from high temperature, and ensure the normal operation of the hydrogen fuel cell; a radiator protective plate 2 is installed on the outside of the radiator, which can protect the radiator and prevent small stones on the ground from being sucked into the radiator and causing wear and leakage.

[0033] A second aspect of the present invention provides a vehicle, on which the hydrogen fuel cell cooling system is installed.

[0034] Specific usage process:

[0035] The hydrogen fuel cell 3 is integrated with a water pump, through which the coolant (e.g., water) in the radiator 1 9 and the radiator 2 16 flows into the hydrogen fuel cell 3 through the cooling water inlet pipe 10 and the water inlet 7 on the hydrogen fuel cell 3. After the coolant flows through the hydrogen fuel cell 3, it flows from the water outlet 5 of the hydrogen fuel cell 3 and the cooling water outlet pipe 11 to the radiator 1 9 and the radiator 2 16. The coolant circulates between the radiator and the hydrogen fuel cell 3, and the heat generated by the hydrogen fuel cell 3 is discharged into the air by the radiator, thereby cooling the hydrogen fuel cell 3.

[0036] The hydrogen fuel cell cooling system of the present invention has a high degree of integration, which is conducive to the standardization and modularization of components; the components are arranged on the rear side of the hydrogen cylinder frame assembly, with a larger space. This arrangement is also suitable for later hydrogen fuel cells with higher power.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
