The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.
Embodiments of the invention: as shown in fig. 1 and 2, an automobile thermal management system comprises a hydrogen fuel electric pile mechanism 1, wherein the hydrogen fuel electric pile mechanism 1 comprises a liquid-gas heat exchanger 2 and a liquid-liquid heat exchanger 3, the liquid-gas heat exchanger 2 is sequentially connected with a driving motor 11, a driving motor controller 12, a DCDC13, a second electronic water pump 14 and a fan controller 15 through pipelines, the liquid-liquid heat exchanger 3 is connected with a warm air core 5 and a high-temperature radiator 6 through pipelines, and the warm air core 5 and the high-temperature radiator 6 are connected with the liquid-liquid heat exchanger 3 in parallel.

The driving motor 11, the driving motor controller 12, the DCDC13, and the fan controller 15 are all provided with heat dissipation channels, and cooling liquid is introduced through the pipeline to realize heat dissipation.
The liquid-gas heat exchanger 2, the first electronic water pump 10, the fan controller 15, the second electronic water pump 14, the DCDC13, the driving motor controller 12, the driving motor 11 and the first three-way valve 8 are sequentially connected through pipelines to form a circulation loop. In winter, heat generated by the driving motor 11, the driving motor controller 12, the DCDC13 and the fan controller 15 is exchanged with the air circuit in the hydrogen fuel cell stack mechanism 1 through the liquid-gas heat exchanger 2, so that the hydrogen fuel cell stack mechanism 1 is quickly heated, and ageing is ensured.
Further, the first three-way valve 8 is further connected with one end of the low-temperature radiator 4 through a pipeline, and the other end of the low-temperature radiator 4 is connected with the water outlet end of the first electronic water pump 10 through a pipeline.
In winter, the low-temperature radiator 4 is mainly used for radiating heat for the driving motor 11, the driving motor controller 12, the DCDC13 and the fan controller 15, and when the environmental temperature is high, the first three-way valve 8 is fully opened, so that the low-temperature radiator 4 radiates heat for the driving motor 11, the driving motor controller 12, the DCDC13, the second electronic water pump 14, the fan controller 15 and the hydrogen fuel cell stack mechanism 1 at the same time.
Further, the water inlet of the warm air core body 5 is connected with the second three-way valve 16 through a pipeline, the other two interfaces of the second three-way valve 16 are respectively connected with the second liquid outlet 17 on the liquid-liquid heat exchanger 3 and the water inlet of the high-temperature radiator 6 through pipelines, the water outlet of the warm air core body 5 is connected with the third three-way valve 18 through a pipeline, and the other two interfaces of the third three-way valve 18 are respectively connected with the second liquid inlet 19 on the liquid-liquid heat exchanger 3 and the water outlet of the high-temperature radiator 6 through pipelines.
By controlling the second three-way valve 16 and the third three-way valve 18, the warm air core 5 can raise the temperature of the hydrogen fuel cell stack mechanism 1, and the high-temperature radiator 6 can lower the temperature of the hydrogen fuel cell stack mechanism 1.
Further, the hydrogen fuel cell stack mechanism 1 further includes a cell stack water pump 20, a cell stack WPTC21, a hydrogen supply module 22, an air compressor 23, a cell stack cell 24, and a blower 25, the liquid-liquid heat exchanger 3 is sequentially connected with the cell stack water pump 20, the cell stack WPTC21, the hydrogen supply module 22, the air compressor 23, the cell stack cell 24 through a liquid pipeline, and the liquid-gas heat exchanger 2 is sequentially connected with the blower 25, the cell stack cell 24 through a gas pipeline.
Still further, still include condenser assembly 26 and evaporimeter assembly 27, condenser assembly 26 cooperates with high temperature radiator 6, and evaporimeter assembly 27 cooperates with warm braw core 5, and condenser assembly 26 is connected with evaporimeter assembly 27 through the refrigerant pipeline, is provided with electric compressor 32 on this refrigerant pipeline, and evaporimeter assembly 27 passes through the refrigerant pipeline and is connected with battery cooler 28, and battery cooler 28 passes through the pipeline and is connected with battery water pump 29, power battery 30 in proper order.
The working principle of the invention is as follows: when the ambient temperature is low in winter, the temperature of the electric pile cell 24 needs to be raised, at this time, the state of the first three-way valve 8 is shown in fig. 3, the cooling liquid does not pass through the low-temperature radiator 4, the driving motor 11, the liquid-gas heat exchanger 2, the first electronic water pump 10, the fan controller 15, the second electronic water pump 14, the DCDC13 and the driving motor controller 12 form a loop, the driving motor 11, the driving motor controller 12, the DCDC13 and the heat released by the fan controller 15 heat the cooling liquid, and the cooling liquid exchanges heat with the liquid-gas heat exchanger 2, so that the electric pile cell 24 is heated by gas, and the high-efficiency temperature rise of the electric pile cell 24 is realized. In this mode, the coolant does not pass through the low-temperature radiator 4. As shown in fig. 1, when the ambient temperature is high, the first three-way valve 8 is fully opened, and the low-temperature radiator 4 simultaneously radiates heat to the liquid-gas heat exchanger 2, the driving motor 11, the driving motor controller 12, the DCDC13, and the fan controller 15. However, when the heat radiation capability of the low temperature radiator 4 is insufficient, the first three-way valve 8 is switched to the state of fig. 4, and at this time, the low temperature radiator 4 radiates heat only to the driving motor 11, the driving motor controller 12, the DCDC13, and the fan controller 15.
In the present invention, there are two circuits coupled to the high-temperature radiator 6, one is a coolant circuit inside the hydrogen fuel cell stack mechanism 1, and the other is a warm air core circuit of the cabin. In winter, the hydrogen supply module 22 needs a certain amount of heat to efficiently produce catalytic reaction, at the moment, the electric pile WPTC21 provides a heat source, and the air compressor 23 can also provide a certain heat source when working, and when the water path in the hydrogen fuel electric pile mechanism 1 is circularly heated and the temperature of the electric pile cell 24 is lower, the liquid-liquid heat exchanger 3 exchanges heat with the warm air core 5, so that the rapid temperature rise is realized. After the temperature rises, the electric pile WPTC21 can be closed, and heat can be provided for the driving cab only through self reaction, so that the aim of saving energy is fulfilled. The states of the second three-way valve 16 and the third three-way valve 18 at this time are shown in fig. 5.
In summer, the high-temperature radiator 6 radiates heat for the hydrogen fuel cell stack mechanism 1, and the warm air core circuit does not participate in the operation, and at this time, the states of the second three-way valve 16 and the third three-way valve 18 are as shown in fig. 6. When the warm air core 5 is required to assist in heat dissipation or participate in work, the second three-way valve 16 and the third three-way valve 18 are controlled to be in a full-open state.
The refrigerant loop and the power battery cooling loop are the same as most main stream pure electric vehicles, and are coupled in the heat management system of the invention through heat exchange of cooling liquid and refrigerant.
While the foregoing is directed to embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
