Thermal management system 100 may be applied to a vehicle, such as a full electric vehicle. In the following description of the present application, the thermal management system 100 is described as being applied to a vehicle, such as a pure electric vehicle.
As shown in fig. 1-3, the thermal management system 100 according to the embodiment of the first aspect of the present invention includes an air conditioning passage 1, a heat exchanging device 4, a first circulation pump 5, and a heating device 6.
Specifically, the air conditioning passage 1 has an air inlet 11 and an air outlet 12, the fan 2 and the heat exchanger 4 are both arranged in the air conditioning passage 1, the heat exchanger 4 has a heat-exchange liquid flow path 43, and the first circulation pump 5 is communicated with the heat-exchange liquid flow path 43.
The heating device 6 has a heating liquid flow path 63, and the heating liquid flow path 63 is connected in series with the first heat exchange circulation pump 5 and the heat-exchange liquid flow path 43 to constitute a first circulation liquid flow circuit 64. The heating device 6 includes at least one of a fuel heater 61 and a first electric heater 62. That is, the heating device 6 may include only the fuel heater 61, only the first electric heater 62, or both the fuel heater 61 and the first electric heater 62.
When the operation mode of the thermal management system 100 is a heating mode, the fan 2 operates, external air flow such as air can enter the air conditioning channel 1 through the air inlet 11, and after heat exchange is performed by the heat exchange device 4, hot air is sent out from the air outlet 12 and can be conveyed to a passenger compartment of a vehicle such as a pure electric vehicle, so that heating is achieved.
Further, heating device 6 and first circulating pump 5 also can work simultaneously, at this moment, heating device 6 can heat liquid such as water in the heating liquid flow path 63, and under the pumping action of first circulating pump 5, water circulates in first circulation flow loop 64 to further heat transfer device 4 on first circulation flow loop 64, thereby can improve heat transfer efficiency of heat transfer device 4 and ambient air, improve the programming rate, and then can promote user experience.

When the heating device 6 includes the first electric heater 62, by adopting the electric heating manner, the heating requirement of the battery pack 7 of the vehicle can be satisfied in an environment where the ambient temperature is lower, and the heating speed is high, so that the temperature rise time can be further shortened.

Since the heat exchanging device 4 includes the warm air core 41 and the second electric heater 42, the second electric heater 42 has no liquid flow path, and the heat exchanging liquid flow path 43 is formed due to the warm air core 41. Therefore, when the operation mode of the thermal management system 100 is the heating mode, the warm air core 41 and the second electric heater 42 enable the air in the air conditioning channel 1 to be doubly heated and then to be discharged from the air outlet 12, so that the heating efficiency of the whole thermal management system 100 is improved. Moreover, when the second electric heater 42 fails, the fuel oil heater 61 and/or the first electric heater 62 can be turned on to heat the hot air core 41, so that the heating effect and the temperature rising speed are ensured.

When the heating device 6 works, only the fuel oil heater 61 can work, and the fuel oil heater 61 can heat the water in the heating liquid flow path 63 flowing through the fuel oil heater, so that electricity can be saved, the electric energy consumption of a vehicle is reduced, and the endurance mileage of the pure electric vehicle is increased. Of course, only the first electric heater 62 may be operated, and the first electric heater 62 may heat the water in the heated liquid flow path 63 flowing therethrough, so that the temperature increase rate of the water is high, and thus the rapid heating can be realized. Alternatively, the oil heater 61 and the first electric heater 62 may also be operated at the same time, so that rapid heating may be further achieved.

For example, when the ambient temperature outside the vehicle is low, in order to ensure that the battery pack 7 of the vehicle can normally operate or increase the charging rate of the battery pack 7, the battery pack 7 may be heated, at this time, at least one of the fuel heater 61 and the first electric heater 62 in the heating device 6 may be turned on, the first interface 81 of the control device 8 may be controlled to communicate with the second interface 82, the third interface 83 may communicate with the fourth interface 84, the battery pack liquid flow path 71 may communicate with the first circulation liquid flow loop 64, the liquid heated by at least one of the fuel heater 61 and the first electric heater 62 may flow from the first circulation liquid flow loop 64 to the battery pack liquid flow path 71, and the liquid with a higher temperature in the battery pack liquid flow path 71 may exchange heat with the battery pack 7, thereby heating the battery pack 7. Therefore, through the arrangement, the thermal management system 100 not only realizes the heating function, but also can heat the battery pack 7, and is simple in structure and easy to realize.
Further, as shown in fig. 2, the thermal management system 100 further includes a second circulation pump 9, and the second circulation pump 9 is connected in series with the battery pack liquid flow path 71. When the liquid in the battery pack liquid flow path 71 has reached the desired temperature, the first port 81 and the third port 83 of the control device 8 and the second port 82 and the fourth port 84 may be controlled to communicate, and at this time, the circulation of the liquid in the second circulation pump 9 and the battery pack 7 may be achieved by the second circulation pump 9, and the temperature of the battery pack 7 may be maintained. Since the heating device 6 and the first circulation pump 5 can be stopped, the energy consumption of the whole thermal management system 100 is reduced, and the cost is reduced.
In some embodiments of the present invention, referring to fig. 2, the first end 641 of the first circulation flow loop 64 is connected to the heat exchange device 4, the heating device 6 and the first circulation pump 5 in the direction of the second end 642, and the battery pack fluid flow path 71 and the second circulation pump 9 are connected between the second port 82 and the fourth port 84 of the control device 8. From this, first circulating pump 5, heating device 6 and heat transfer device 4 concentrate and arrange, can concentrate the heating to water, can realize the rapid heating up of water. Moreover, first circulating pump 5 and second circulating pump 9 interval are arranged on whole circulation route, when giving battery package 7 heating, when first circulating pump 5 and second circulating pump 9 simultaneous working, can alleviate first circulating pump 5 and second circulating pump 9 pumping pressure, prolong first circulating pump 5 and second circulating pump 9's life.

Alternatively, as shown in fig. 1, an evaporator 3 and a cooling/heating air door 13 are provided in the air-conditioning passage 1. Specifically, the air-conditioning passage 1 includes a cooling passage and a heating passage. When the cold and warm air door 13 is opened to the position of the cold air door, a refrigeration channel is formed; when the cold and warm air door 13 is opened to the position of the warm air door, a heating channel is formed. The evaporator 3 is used for evaporative cooling of the thermal management system 100, when the air conditioning channel 1 performs a cooling working condition, heating work is not performed in the air conditioning channel 1, the cold and warm air door 13 is opened to the position of the cold air door, external air flow such as air enters the air conditioning channel 1 under the action of the fan 2, and the air flow is cooled by the evaporator 3 and then is sent out through the cooling channel; similarly, when the thermal management system 100 is used for heating, the evaporator 3 does not perform cooling, the cold-warm air door 13 is opened to the position of the warm-air door, and external air flows, such as air and the like, enter the air conditioning channel 1 under the action of the fan 2, pass through the evaporator 3 which does not operate, flow from the position of the warm-air door to the heat exchanging device 4, and are sent out through the heating channel after being subjected to heat exchange and temperature increase through the heat exchanging device 4. Therefore, the thermal management system 100 can be switched between the cooling mode and the heating mode according to the user requirements, and has a simple structure and convenient operation.
Alternatively, referring to fig. 1, the warm air core 41 is provided upstream of the second electric heater 42. That is, the air entering the air conditioning duct 1 from the air inlet 11 passes through the evaporator 3 and the air door 13, then passes through the hot air core 41 to exchange heat, then flows to the second electric heater 42, and finally is discharged from the air outlet 12. Thus, the heating effect of the thermal management system 100 is ensured.
