Definitions
- the embodiments of the present application relate to the field of thermal management technology, and in particular to a thermal management system and a vehicle.
- Vehicles use batteries as energy sources. Due to the limitation of battery power, vehicles have higher requirements for energy utilization. In addition, in addition to meeting the heating and cooling needs of the passenger compartment, the thermal management system of electric vehicles must also heat or cool the vehicle's batteries or electric drives to keep them operating within a reasonable temperature range.
- a thermal management system with a heat pump or a heater is usually used to meet the heating and cooling needs of the passenger compartment.
- a thermal management system with a heat pump or a heater is usually used to meet the heating and cooling needs of the passenger compartment.
- the temperature inside the passenger compartment is still low and cannot meet the heating needs of the passengers.
- the embodiment of the present application provides a thermal management system and a vehicle.
- the thermal management system can increase the temperature in the passenger compartment of the vehicle and meet the heating needs of the user.
- the first aspect of the embodiment of the present application provides a thermal management system, which at least includes: a first cooling medium circuit and a second cooling medium circuit.
- the first cooling medium circuit includes a compressor, a first heat exchanger and a second heat exchanger.
- the first heat exchanger includes a first flow channel and a second flow channel isolated from each other, and the second heat exchanger includes a third flow channel and a fourth flow channel isolated from each other.
- the input end of the compressor is connected to the output end of the third flow channel and is used to be connected to the output end of the evaporation core provided on the vehicle, and the output end of the compressor is connected to the input end of the second flow channel.
- the input end of the first flow channel is used to be connected to the output end of the warm air core of the vehicle.
- the output end of the second flow channel is connected to the input end of the third flow channel, and the output end of the second flow channel is also used to be connected to the input end of the evaporation core.
- the input end of the third flow channel is also used to be connected to the output end of the evaporation core.
- the second cooling medium circuit includes a valve group having at least four interface ends. The first interface end and the second interface end of the valve group are respectively connected to the input end and the output end of the fourth flow channel, the third interface end of the valve group is connected to the output end of the first flow channel, and the fourth interface end of the valve group is used to be connected to the input end of the warm air core.
- the thermal management system is at least configured with a heat pump mode.
- the first cooling medium in the first flow channel flows into the evaporation core and exchanges heat with the air around the evaporation core, and the first cooling medium after heat exchange returns to the compressor through the third flow channel.
- the air that has exchanged heat with the first cooling medium in the evaporation core also exchanges heat with the second cooling medium in the warm air core.
- the first cooling medium in the second flow channel can enter the evaporation core after exchanging heat with the second cooling medium in the first flow channel, and the first cooling medium can exchange heat with the air around the evaporation core through the evaporation core to increase the temperature of the air around the evaporation core, thereby achieving the first heating of the air.
- the second cooling medium in the warm air core will also exchange heat with the air after the heat exchange with the first cooling medium in the evaporation core, thereby achieving the second heating of the air. Since the temperature of the first cooling medium in the evaporation core is lower than the temperature of the second cooling medium in the warm air core, the air entering the passenger compartment of the vehicle will first be heated by the evaporation core, and the heated air will then be heated by the warm air core, so that the heating process of the air achieves the effect of "secondary heating".
- the evaporator core can be reused as a pre-heater (condenser), so that the evaporator core and the heater core can reheat the air entering the passenger compartment, which can increase the heating capacity and energy efficiency ratio COP of the thermal management system, thereby increasing the temperature in the passenger compartment and meeting the user's heating needs.
- the first cooling medium circuit further includes: a first throttle valve and a second throttle valve.
- the output end of the second flow channel is connected to the input end of the evaporation core through the first throttle valve.
- the input end of the third flow channel is connected to the output end of the second flow channel and the output end of the evaporation core respectively through the second throttle valve.
- the flow rate of the first cooling medium flowing into the evaporation core can be controlled by the first throttle valve, so that the heating effect of the evaporation core can meet the user's needs as much as possible.
- the flow rate of the first cooling medium flowing into the third flow channel can be controlled by the second throttle valve, which helps to improve the use effect of the second heat exchanger.
- the first cooling medium circuit further includes: a first stop valve and a second stop valve.
- the output end of the second flow channel is connected to the input end of the third flow channel through the first stop valve.
- the input end of the compressor is connected to the output end of the evaporating core through the second stop valve.
- the first cooling medium circuit further includes: a first one-way valve, the output end of the evaporation core is connected to the input end of the third flow channel through the first one-way valve, and the first one-way valve is used to allow the first cooling medium to flow from the output end of the evaporation core to the input end of the third flow channel.
- the thermal management system executes the heat pump mode, it can ensure that the first cooling medium always flows from the evaporation core into the third flow channel.
- the first one-way valve can prevent the first cooling medium from flowing from the third flow channel to the evaporation core.
- the first cooling medium cannot flow from the evaporation core into the third flow channel, nor can it flow from the third flow channel into the evaporation core (through the one-way flow of the first one-way valve).
- the first cooling medium can flow from the evaporation core to the second throttle valve, but since the second throttle valve is closed, the first cooling medium cannot flow into the third flow channel, thereby not affecting the current function of the system.
- the first cooling medium circuit further includes: a liquid storage tank, the input end of the liquid storage tank is connected to the output end of the second flow channel, and the output end of the liquid storage tank is respectively connected to the input end of the third flow channel and the input end of the evaporation core.
- the liquid storage tank can adjust the total amount of the first cooling medium in the first cooling medium circuit according to the cooling effect or the heating effect. For example, when the total amount of the first cooling medium decreases, the liquid storage tank can automatically store more first cooling medium.
- the second cooling medium circuit further includes: an electric heater and a warm air water pump.
- the input end of the electric heater is connected to the output end of the warm air water pump, and the output end of the electric heater is connected to the input end of the warm air core.
- the input end of the warm air water pump is connected to the fourth interface end of the valve group.
- the warm air water pump can transport the second cooling medium into the warm air core, so that the second cooling medium can exchange heat with the heat-exchanged air through the warm air core, and heat the air entering the passenger compartment for the second time.
- the electric heater can increase the temperature of the second cooling medium, which helps to improve the heating effect of the thermal management system. For example, it can increase the heat exchange amount between the second cooling medium and the heat-exchanged air, and can further increase the temperature of the air entering the passenger compartment.
- the valve group has at least six interface ends
- the second cooling medium circuit further includes: an electric drive pipeline, an electric drive water pump, and an electric driver.
- the input end of the electric drive pipeline is connected to the fifth interface end of the valve group, and the output end of the electric drive pipeline is connected to the sixth interface end of the valve group.

- the second cooling medium circuit further includes: a radiator, through which the input end of the electric drive pipeline is connected to the fifth interface end of the valve group.
- the second cooling medium can exchange heat with the air around the radiator through the radiator to control the temperature of the second cooling medium. For example, when the temperature of the second cooling medium is increased or decreased.
- the second cooling medium circuit further includes: a kettle, which is connected to the electric drive pipeline. Since the kettle is a container with an upper end open, the kettle can filter out the gas, leaving only the liquid second cooling medium circulating in the second cooling medium circuit, thereby improving the cooling effect or heating effect.
- the second cooling medium circuit also includes: a battery pipeline, a battery water pump and a battery pack, and the valve group has at least eight interface ends.
- the input end and the output end of the battery pipeline are respectively connected to the seventh interface end and the eighth interface end of the valve group.
- the battery water pump and the battery pack are respectively connected in series to the battery pipeline.
- the seventh interface end of the valve group is also connected to the input end of the first flow channel through a second one-way valve, and the second one-way valve is used to allow the second cooling medium to flow from the seventh interface end of the valve group to the input end of the first flow channel, thereby increasing the working conditions of the thermal management system.
- the second cooling medium circuit further includes: a three-way valve, the input end of the three-way valve is connected to the output end of the heater core, the first output end of the three-way valve is connected to the input end of the first flow channel, and the second output end of the three-way valve is connected to the input end of the battery water pump.
- the second cooling medium in the heater core can not only return to the valve group through the first flow channel, but also flow to the battery water pump through the three-way valve, thereby increasing the working conditions of the thermal management system.
- the valve group is a nine-way valve.
- Implementing the regulating structure of the valve group by the nine-way valve can reduce the difficulty of pipeline design, reduce the volume occupied by the valve group, and help improve the integration of the thermal management system.

- Electric vehicles use batteries as energy sources. Due to the limitation of battery power, electric vehicles have higher requirements for energy utilization.
- the thermal management system is an important part of electric vehicles. It is responsible for ensuring the comfort of the passenger compartment and the thermal safety of the electric drive system and battery system. Its energy utilization efficiency is directly related to the energy consumption and endurance of the entire vehicle. In the thermal management system, the passenger compartment thermal management module accounts for the largest proportion of energy consumption, which has the functions of cooling in summer and heating in winter.
- FIG. 1 is a schematic diagram of the structure of a thermal management system in the related art.
- the thermal management system in the related art includes a housing 12 and a first circuit 14 and a second circuit 16 at least partially arranged in the housing 12.
- the first circuit includes a compressor 22, a condenser 24, a liquid storage tank 26, an electronic expansion valve 28 and a cooler 30, all of which are arranged in series.
- the second circuit 16 includes a water inlet 34, a first multi-way valve 36, a low-temperature radiator 38, a cooler 30, a water tank 40, a water pump 42, a PTC (Positive temperature efficiency, positive proportional coefficient heater) 44, a second multi-way valve 46 and a plurality of water outlets 48.
- the thermal management system By controlling the opening of the first multi-way valve 36, it is determined that the water system passes through the low-temperature radiator 38 through the pipeline 56 to realize the low cooling mode, passes through the cooler 30 through the pipeline 54 to realize the high cooling mode, and directly returns to the water storage tank 40 through the PTC44 and the pipeline 58 to realize the heating mode. Therefore, the thermal management system is configured with three modes: high cooling mode, low cooling mode and heating mode.
- the thermal management system has the following problems: 1.
- the thermal management system can only heat and cool components such as batteries and electric drives, and cannot take into account the heating and cooling of the passenger compartment at the same time. 2.
- the heating function is completely dependent on the heater, and the energy efficiency ratio is low.
- FIG2 is a schematic diagram of the structure of another thermal management system in the related art.
- the thermal management system in the related art may include an electric compressor 1, a plate heat exchanger 2, a first electronic expansion valve 30, a second electronic expansion valve 25, a battery cooler 7, a gas-liquid separator 8, a first electronic valve 27, a second electronic valve 29, a third electronic valve 28, a fourth electronic valve 26, a check valve 24, a first expansion water tank 14, a radiator, a first water pump 12, and a water circuit four-way valve 21.
- the plate heat exchanger 2 acts as a condenser in the cooling mode, and takes away the heat through the electric drive water circuit.
- the plate heat exchanger 2 acts as an evaporator in the heating mode
- the heat generated by the electric drive can be recovered as waste heat.
- the thermal management system can heat the passenger compartment, the heating of the passenger compartment and the battery is achieved by a heater (such as PTC), and the heating efficiency is low.
- the integration of the entire thermal management system is low, and the installation components and pipelines are relatively scattered.
- heat pump heating technology refers to compressing the refrigerant in a vapor state through a compressor to do work, releasing the heat of the high-temperature and high-pressure refrigerant to the passenger compartment, and then throttling and expanding through an expansion valve, absorbing heat from the outdoor low-temperature environment, and then returning to the compressor for compression.
- the heat pump system increases the energy quality of the heat in the outdoor low-temperature environment air through the compression action of the compressor and releases it to places where heat is needed, such as the passenger compartment or battery pack.

- the second cooling medium with increased temperature enters the warm air core 43 through the valve group 31 and releases heat to increase the temperature of the air heated by the evaporation core 50. Since the temperature of the first cooling medium in the evaporation core 50 is lower than the temperature of the second cooling medium in the warm air core 43 and higher than the temperature of the low-temperature air, the heating process of the air achieves the effect of "secondary heating".
- the evaporator core 50 is reused as a pre-heater (condenser), and the low-temperature air entering the passenger compartment is first heated by the evaporator core 50, and then heated by the warm air core 43, thereby achieving secondary heating of the air, thereby increasing the temperature of the air entering the passenger compartment, and further increasing the temperature inside the passenger compartment.

Since the first cooling medium does not have a throttling effect in the full-pass throttle valve, no pressure drop occurs in FIG. 9 .
- the first throttle valve 24 may also be a non-fully open throttle valve, that is, when the first throttle valve 24 is fully open, the first cooling medium still has a pressure drop loss after passing through the first throttle valve 24, and a throttling effect will still occur.

- the first one-way valve 281 can play a role in disconnecting the first cooling medium from the evaporation core 50 to the third flow channel, that is, the first one-way valve 281 has a disconnection function.
- the principle of the disconnection function is: the pressure of the first cooling medium flowing out of the evaporation core 50 is small, which is not enough to pass through the resistance generated by the mechanical structure inside the first one-way valve 281, so the first cooling medium cannot flow into the third flow channel.
