Thermal management system and vehicle

Abstract

The present invention relates to the field of vehicle technology and specifically discloses a thermal management system comprising a first branch system and a second branch system. When the passenger compartment requires heating, the first and second interfaces of a first valve are connected, allowing the coolant in the engine to enter a heater core through the first valve, thereby heating the passenger compartment. When the battery requires heating, the first and second interfaces of a second valve are connected, and the first and second interfaces of a third valve are connected. A second liquid pump operates, causing the coolant flowing through the battery to first flow through a heater, allowing the coolant in the engine to enter the heater through the first valve. The heater heats the coolant flowing into the battery, thereby heating the battery. This thermal management system enhances its ability to coordinate with each other and fully utilizes the residual heat of each branch system. This not only improves energy conservation but also reduces the number of components in the thermal management system, lowers manufacturing costs, and reduces occupied space.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0031] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0032] like Figure 1 As shown, this embodiment provides a thermal management system, which includes a first branch system and a second branch system, wherein the first branch system includes a high-temperature radiator 11, a first liquid pump 12, a first valve 13, a heater core 14 and a heater 15, the liquid outlet of the high-temperature radiator 11 is used to communicate with the coolant inlet of the engine 6 through the first liquid pump 12, the coolant outlet of the engine 6 is communicated with the liquid inlet of the high-temperature radiator 11, the first interface of the first valve 13 is communicated with the coolant outlet of the engine 6, the second interface of the first valve 13 is communicated with the liquid inlet of the heater core 14 and the first medium inlet of the heater 15 respectively, the liquid outlet of the heater core 14 and the heater 15 are connected. The first medium outlet of the heater 15 is respectively connected to the liquid inlet of the first liquid pump 12, and the heater core 14 is used to heat the passenger compartment. The second branch system includes a cooling module, a second liquid pump 21, a second valve 22, and a third valve 23. The first interface of the second valve 22 is connected to the first medium inlet of the cooling module, the first medium outlet of the cooling module is connected to the first interface of the third valve 23, the second interface of the third valve 23 is connected to the liquid outlet of the second liquid pump 21, the liquid inlet of the second liquid pump 21 is connected to the second medium inlet of the heater 15, the second medium outlet of the heater 15 is connected to the coolant inlet of the battery 5, and the coolant outlet of the battery 5 is connected to the second interface of the second valve 22. When a vehicle equipped with this thermal management system is driving, if the engine 6 is running, the first liquid pump 12 will operate, causing the coolant in the engine 6 to circulate between the high-temperature radiator 11 and the engine 6, thereby removing heat from the engine 6. When the passenger compartment needs to be heated, the first and second interfaces of the first valve 13 are connected, and the coolant in the engine 6 enters the heater core 14 through the first valve 13, thereby heating the passenger compartment. When the battery 5 needs to be heated, the first and second interfaces of the second valve 22 and the first and second interfaces of the third valve 23 are connected, and the second liquid pump 21 is activated, causing the coolant flowing through the battery 5 to first flow through the heater 15. The coolant in the engine 6 enters the heater 15 through the first valve 13, and the heater 15 heats the coolant flowing into the battery 5, thereby heating the battery 5. This thermal management system improves the ability to coordinate with each other and fully utilizes the residual heat of each branch system. This not only improves energy conservation, but also reduces the number of components in the thermal management system, lowers manufacturing costs, and reduces the space occupied.

[0033] Optionally, the first branch system further includes a thermostatic valve 16, wherein a first interface of the thermostatic valve 16 is connected to the liquid inlet of the high-temperature radiator 11, a second interface of the thermostatic valve 16 is connected to the liquid outlet of the engine 6, and a third interface of the thermostatic valve 16 is connected to the liquid inlet of the first liquid pump 12. In this embodiment, a portion of the coolant flowing out of the liquid outlet of the engine 6 flows to the high-temperature radiator 11 through the first and second interfaces of the thermostat for heat dissipation, and the coolant after heat dissipation flows back to the first liquid pump 12. The remaining portion flows directly to the first liquid pump 12 through the third and second interfaces of the thermostat. Based on the measured real-time temperature of the engine 6, the thermostat can adjust the opening between the first and second interfaces of the thermostat, as well as the opening between the second and third interfaces, in real time, so that the amount of coolant flowing through the first interface of the thermostat is different from the amount of coolant flowing through the third interface of the thermostat, thereby maintaining a constant temperature of the engine 6.

[0034] Optionally, the first branch system also includes an electric heater 17, a third liquid pump 18, a first stop valve 19 and a second stop valve 20. The liquid outlet of the electric heater 17 is connected to the third interface of the first valve 13, the liquid inlet of the electric heater 17 is connected to the liquid outlet of the third liquid pump 18, and the liquid inlet of the third liquid pump 18 is respectively connected to the liquid outlet of the heater core 14 and the first medium outlet of the heater 15. The first stop valve 19 controls the opening of the liquid inlet of the heater core 14, and the second stop valve 20 controls the opening of the first medium inlet of the heater 15. In this embodiment, when the engine 6 stops working, if the passenger compartment and the battery 5 need to be heated, the electric heater 17 starts working. At this time, the second interface and the third interface of the first valve 13 are connected, and the coolant heated by the electric heater 17 can enter the heater core 14 and the heater 15 respectively through the first stop valve 19 and the second stop valve 20, thereby heating the passenger compartment and the battery 5. When the passenger compartment does not need to be heated, it is only necessary to control the first stop valve 19 to close the opening of the liquid inlet of the heater core 14 to stop heating the passenger compartment. When the battery 5 does not need to be heated, it is only necessary to control the second stop valve 20 to close the opening of the first medium inlet of the heater 15 to stop heating the passenger compartment.

At this time, the cooler 26, the second liquid pump 21, the heater 15, and the cooling plate of the battery 5 form a ring loop.
