DETAILED DESCRIPTION

[0057] Embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. The embodiments described with reference to the accompanying drawings are exemplary.

[0058] A heat exchange module according to an embodiment of the present disclosure is described below with reference to FIG. 1.

[0059] FIG. 1 is a block diagram of a heat exchange module according to an embodiment of the present disclosure. As shown in FIG. 1, the heat exchange module 10 according to an embodiment of the present disclosure includes a plate heat exchanger 11 and a driver area air conditioning system 12.

[0060] In some embodiments, the plate heat exchanger 11 is a device for heat exchange, which can be composed of a series of metal plates with gaps between the plates, and heat conduction is carried out through the fluid between the plates. In this case, the plate heat exchanger 11 exchanges heat with the passenger area air conditioning system 20, i.e., through the plate heat exchanger 11, the passenger area air conditioning system 20 can exchange heat with other areas. For example, the plate heat exchanger 11 is in communication with the vehicle air conditioning system, and the refrigerant of the vehicle air conditioning system flows through the plate heat exchanger 11, and the cooling water of the driver area air conditioning system 12 exchanges heat with the refrigerant flowing through the plate heat exchanger 11 through the plate heat exchanger 11, thereby achieving cooling or heating of the driver area.

[0061] In some embodiments, the plate heat exchanger 11 can be made of materials with high thermal conductivity and corrosion resistance to ensure efficient heat exchange process. In addition, the size and shape of the plate heat exchanger 11 can be adjusted as needed to adapt to the layout and space limitations of different vehicles.

[0062] In some embodiments, the driver area air conditioning system 12 can be a system for cooling the driver area of the vehicle. The driver area air conditioning system 12 includes a first heat exchanger 121, which can be of different types of heat exchangers, such as plate heat exchangers, fin heat exchangers, etc., and the specific type of the first heat exchanger 121 depends on factors such as system design requirements, space limitations, and heat exchange efficiency.

[0063] As shown in FIG. 1, the first heat exchanger 121 is in communication with the plate heat exchanger 11 to perform refrigeration or heating for the driver area of the vehicle. The working principle is that the cooling water passes through the plate heat exchanger 11 and exchanges heat with the metal plates inside the plate heat exchanger 11. In this process, the temperature of the cooling water will be reduced, thereby achieving the effect of refrigeration. The first heat exchanger 121 is a device connected to the plate heat exchanger 11, and a blower 127 can be installed beside it. After the cooling water flows through the plate heat exchanger 11, it enters the first heat exchanger 121, and the blower 127 sucks the air in the driver area of the vehicle and exchanges heat through the first heat exchanger 121. In this process, the cold energy released by the cooling water is transferred to the air passing through the first heat exchanger 121, so that the temperature of the air is reduced. Finally, the blower 127 blows out the cold air after heat exchange, thereby achieving the effect of refrigeration for the driver area of the vehicle. The working principle ensures the effective recycling of the cooling water in the driver area air conditioning system 12 and the delivery of cold air to the driver area through the first heat exchanger 121 and the blower 127 to provide a comfortable driving environment.

[0064] According to the heat exchange module 10 of the embodiment of the present disclosure, by adopting the plate heat exchanger 11 to exchange heat with the passenger area air conditioning system 20 and connecting it with the first heat exchanger 121 of the driver area air conditioning system 12, it means that the cooling water in the driver area air conditioning system 12 can exchange heat with the plate heat exchanger 11 to achieve refrigeration or heating for the driver area of the vehicle. This design avoids the need to additionally set up a separate driver area air conditioning system 12, realizes the integration of the passenger area air conditioning system 20 and the driver area air conditioning system 12, reduces the number of parts, reduces the overall volume and weight of the system, simplifies the structure of the system, thereby reducing the manufacturing cost and improving the market competitiveness of the vehicle.

[0065] FIG. 2 is a connection diagram of the first switching unit 122 according to an embodiment of the present disclosure. As shown in FIG. 2, the driver area air conditioning system 12 further comprises a first switching unit 122. The first switching unit 122 is an important component in the driver area air conditioning system 12, which can be realized by one component or a combination of multiple components to realize the control function. The first switching unit 122 is connected between the first heat exchanger 121 and the plate heat exchanger 11, and is used to control the communication state of the first heat exchanger 121 and the plate heat exchanger 11. It can control whether the cooling water can flow from the plate heat exchanger 11 to the first heat exchanger 121, thereby adjusting the refrigeration effect of the driver area of the vehicle.

[0066] In some embodiments, the working state of the first switching unit 122 can be adjusted through the air conditioning system control panel or the automatic control system of the vehicle. According to the needs of the driver or the change of the ambient temperature, the system can automatically adjust the opening and closing state of the first switching unit 122 to achieve comfortable control of the driver area. In addition, the design of the first switching unit 122 can adopt different structures and control modes according to actual needs to adapt to the requirements of different vehicles and the refrigeration needs of the driver area of the vehicle.

[0067] FIG. 3 is a schematic diagram of the thermal management system 1 according to one embodiment of the present disclosure. As shown in FIG. 3, the first switching unit 122 can include a first three-way valve 1221.

[0068] The first three-way valve 1221 controls the flow direction and flow distribution of the cooling water between the first heat exchanger 121 and the plate heat exchanger 11. The first three-way valve 1221 includes a first valve port, a second valve port, and a third valve port. The first valve port is connected to the first end of the first heat exchanger 121, the second end of the first heat exchanger 121 is connected to the first end of the plate heat exchanger 11 through the defrosting water tank 123 and the defrosting water pump 124, the second valve port of the first three-way valve 1221 is connected to the second end of the plate heat exchanger 11, and the third valve port of the first three-way valve 1221 is connected to the first end of the plate heat exchanger 11 through the defrosting water tank 123 and the defrosting water pump 124.

[0069] Specifically, when the vehicle driver area needs to be refrigerated, the cooling water in the defrosting water tank 123 is pressurized by the defrosting water pump 124 and then flows to the plate heat exchanger 11. After the passenger area air conditioning system 20 exchanges heat with the plate heat exchanger 11, the temperature of the cooling water is reduced. Then, according to the control signal of the system, the first valve port of the first three-way valve 1221 is kept in communication with the second valve port, so that the cooling water flows from the second end of the plate heat exchanger 11 to the first heat exchanger 121 through the first three-way valve 1221, the air blower 127 inhales the air in the vehicle driver area and exchanges heat with the first heat exchanger 121, and then blows out the cold air. After being exchanged by the first heat exchanger 121, the cooling water flows out from the second end of the first heat exchanger 121 and returns to the defrosting water tank 123. By continuously circulating the above process, the refrigeration effect of the vehicle driver area can be achieved. When the vehicle driver area does not need to be refrigerated, the second valve port and the third valve port of the first three-way valve 1221 can be kept in communication, so that the cooling water flows out from the plate heat exchanger 11 and returns to the defrosting water tank 123 again. The cooling water cannot pass through the first heat exchanger 121 and the air blower 127, so as to keep the temperature of the vehicle driver area stable.

[0070] In some embodiments, the control mode of the first three-way valve 1221 can adopt electronic control or other control modes, and the specific control mode can be selected according to system requirements and design requirements. In addition, the design of the defrosting water tank 123 and the defrosting water pump 124 also needs to consider the working environment and refrigeration requirements of the system to ensure the stable operation and high efficiency of the heat exchange system.

[0071] In other embodiments, as shown in FIG. 12, the first switching unit 122 can also be implemented by multiple switch valves, for example, the first switching unit 122 can include a first switch valve 21 and a second switch valve 22.

[0072] Wherein the first end of the first switch valve 21 is connected with the first end of the first heat exchanger 121, the second end of the first heat exchanger 121 is connected with the first end of the plate heat exchanger 11 through the defrosting water tank 123 and the defrosting water pump 124, and the second end of the first switch valve 21 is connected with the second end of the plate heat exchanger 11. The first end of the second switch valve 22 is connected with the first end of the plate heat exchanger 11 through the defrosting water tank 123 and the defrosting water pump 124, and the second end of the second switch valve 22 is connected with the second end of the plate heat exchanger 11.

[0073] Specifically, when the vehicle driver area needs to be cooled, the cooling water in the defrosting water tank 123 is controlled to flow through the plate heat exchanger 11 after being pressurized by the defrosting water pump 124; the passenger area air conditioning system 20 exchanges heat with the plate heat exchanger 11, so that the temperature of the cooling water is reduced; then, according to the control signal of the system, the first switch valve 21 is controlled to be opened and the second switch valve 22 is controlled to be closed, so that the cooling water flows from the plate heat exchanger 11 to the first heat exchanger 121 through the first switch valve 21, and the air blower 127 inhales the air in the vehicle driver area and exchanges heat with the first heat exchanger 121, and then blows out the cold air; after being exchanged by the first heat exchanger 121, the cooling water flows out from the second end of the first heat exchanger 121 and returns to the defrosting water tank 123. By continuously circulating the above process, the cooling effect of the vehicle driver area can be achieved. When the vehicle driver area does not need to be cooled, the second switch valve 22 can be controlled to be opened and the first switch valve 21 can be controlled to be closed, so that the cooling water flows out from the plate heat exchanger 11 and returns to the defrosting water tank 123 again, and the cooling water cannot pass through the first heat exchanger 121 and the air blower 127, so as to keep the temperature of the vehicle driver area stable.

[0074] In some embodiments, when the system detects that the driver area has a cooling demand, the first switching unit 122 is controlled to make the first end of the first heat exchanger 121 communicate with the second end of the plate heat exchanger 11. In this way, the cooling water in the defrosting water tank 123 is pressurized by the defrosting water pump 124 and then flows through the plate heat exchanger 11, and then from the plate heat exchanger 11 into the first heat exchanger 121, to perform heat exchange and provide cooling effect. When the system detects that the driver area has no cooling demand, the first switching unit 122 is controlled to cut off the communication between the first end of the first heat exchanger 121 and the second end of the plate heat exchanger 11. In this way, the cooling water cannot flow through the first heat exchanger 121, but is directly returned to the defrosting water tank 123 and no longer participates in the heat exchange process. In this way, the temperature of the driver area can be kept stable. Therefore, the specific control strategy of the first switching unit 122 can be optimized and adjusted according to the actual demand and design requirements of the vehicle driver area.

[0075] As shown in FIG. 3, the driver area air conditioning system 12 further comprises a first electric heating unit 125. The first electric heating unit 125 can convert electrical energy into heat energy to provide additional heat for the driver area, so as to meet the heating demand of the driver in cold environment. It can quickly provide a warm driving environment when the vehicle starts, especially when the engine is cold started or the ambient temperature is low, which helps to improve the comfort and safety of the driver.

[0076] In some embodiments, the first electric heating unit 125 is arranged close to the first heat exchanger 121 for heating the driver area of the vehicle. This arrangement helps to ensure that the heat generated by the first electric heating unit 125 can be effectively absorbed by the first heat exchanger 121 and transmitted to the driver area of the vehicle, thereby achieving rapid heating of the driver area of the vehicle. This coordinated design can improve heating efficiency and reduce energy waste.

[0077] In some embodiments of the present disclosure, the first electric heating unit 125 can adopt a PTC (Positive Temperature Coefficient) electric heater. The PTC electric heater is a technology commonly used in automobile heating systems, which has the characteristic of automatically adjusting power according to temperature change, thereby improving heating efficiency and energy saving. In addition, the first electric heating unit 125 can be designed according to the specific requirements of the vehicle and the size of the driver area, and the power and layout of the first electric heating unit 125 can be adjusted to ensure that the expected heating effect is achieved.

[0078] In some embodiments, the heat exchange module 10 further comprises a battery thermal management water circuit 13 and a second switching unit 155. The battery thermal management water circuit 13 can be a water circuit system for managing the heat of the battery. In an electric vehicle, the temperature control of the battery is crucial, and both too high or too low temperature can affect the performance and life of the battery. The battery thermal management water circuit 13 can control and regulate the temperature of the battery through water circulation to maintain the battery within a suitable working temperature range, thereby improving the safety and reliability of the battery and prolonging the service life of the battery.

[0079] In some embodiments, the first end of the battery thermal management water circuit 13 is in communication with the first end of the plate heat exchanger 11, which means that the heat generated by the battery system can be transferred to the plate heat exchanger 11 for processing through the battery thermal management water circuit 13. This design helps to ensure that the battery avoids overheating damage due to excessive temperature when working.

[0080] In some embodiments, the second switching unit 155 is an important component in the battery thermal management water circuit 13, which can be implemented by one component or a combination of multiple components to realize the control function. The second switching unit 155 is arranged between the second end of the battery thermal management water circuit 13 and the second end of the plate heat exchanger 11, and is used to control the communication state between the battery thermal management water circuit 13 and the plate heat exchanger 11. By controlling the state of the second switching unit 155, the communication state between the battery thermal management water circuit 13 and the plate heat exchanger 11 can be adjusted, so as to adjust the temperature of the battery and ensure it within a suitable working range.

[0081] It should be noted that in the embodiments, the first end and the second end of the battery thermal management water circuit 13 can be the terminal ends of the battery thermal management water circuit 13, or the end portions at some intermediate positions.

[0082] In some embodiments, the control mode of the second switching unit 155 can adopt electronic control or mechanical control to accurately adjust the temperature of the battery according to the system requirements.

[0083] As shown in FIG. 3, the second switching unit 155 comprises a second three-way valve 15. The second three-way valve 15 is also a valve device comprising three valve ports. The first valve port of the second three-way valve 15 is connected with the second end of the battery thermal management water circuit 13, the second valve port of the second three-way valve 15 is connected with the second end of the plate heat exchanger 11, and the third valve port of the second three-way valve 15 is connected with the first end of the battery thermal management water circuit 13.

[0084] Specifically, when the battery needs to be cooled, the cooling water in the defrosting water tank 123 is pressurized by the defrosting water pump 124 and then flows through the plate heat exchanger 11. After the passenger area air conditioning system 20 exchanges heat with the plate heat exchanger 11, the temperature of the cooling water is reduced. Then, according to the control signal of the system, the second valve port of the second three-way valve 15 is controlled to communicate with the first valve port, and the cooling liquid can flow from the second end of the plate heat exchanger 11 to the second end of the battery thermal management water circuit 13. By flowing the cooling water in the battery thermal management water circuit 13, the heat generated by the battery can be effectively absorbed and retransmitted to the plate heat exchanger 11, which is dissipated to the external environment through the plate heat exchanger 11, thereby achieving heat dissipation of the battery. When the battery does not need to be cooled, the second valve port of the second three-way valve 15 can be controlled to close the communication with the first valve port to cut off the connection between the battery thermal management water circuit 13 and the plate heat exchanger 11, preventing the cooling liquid from flowing through the battery thermal management water circuit 13, so that the battery is no longer cooled.

[0085] In some embodiments, the control of the second three-way valve 15 can adopt electronic control or other appropriate control mode to adjust the flow direction and flow rate of the cooling water according to the system requirements and design requirements, so as to realize precise control of the battery temperature.

[0086] In other embodiments, the second switching unit 155 can also be implemented by a plurality of on-off valves, for example, the second switching unit 155 can include a third on-off valve 23 and a fourth on-off valve 24.

[0087] Wherein the first end of the third on-off valve 23 is connected with the second end of the battery thermal management water circuit 13, and the second end of the third on-off valve 23 is connected with the second end of the plate heat exchanger 11. The first end of the fourth on-off valve 24 is connected with the second end of the battery thermal management water circuit 13, and the second end of the fourth on-off valve 24 is connected with the first end of the battery thermal management water circuit.

[0088] Specifically, when the battery needs to be cooled, the cooling water in the defrosting water tank 123 is pressurized by the defrosting water pump 124 and then flows through the plate heat exchanger 11. After the passenger area air conditioning system 20 exchanges heat with the plate heat exchanger 11, the temperature of the cooling water is reduced. Then, according to the control signal of the system, the third switch valve 23 is opened and the fourth switch valve 24 is closed, so that the cooling water flows from the plate heat exchanger 11 into the battery thermal management water circuit 13 through the third switch valve 23. By flowing the cooling water in the battery thermal management water circuit 13, the heat generated by the battery can be effectively absorbed and transferred to the plate heat exchanger 11. By continuously circulating the above process, the cooling of the battery can be achieved. When the battery does not need to be cooled, the fourth switch valve 24 can be opened and the third switch valve 23 can be closed to cut off the connection between the battery thermal management water circuit 13 and the plate heat exchanger 11, preventing the cooling liquid from flowing through the battery thermal management water circuit 13, so that the battery is no longer cooled.

[0089] In some embodiments, the control of the third switch valve 23 and the fourth switch valve 24 can use electronic control or other appropriate control methods to adjust the flow direction and flow rate of the cooling water according to the system requirements and design requirements, so as to achieve precise control of the battery temperature.

[0090] As shown in FIG. 3, the battery thermal management water circuit 13 includes a battery water tank 131, a battery water pump 132, and a battery pack 133. The battery water tank 131 is a container for storing cooling liquid such as cooling water, which provides cooling water to the battery pack 133. The battery water pump 132 can push the cooling water from the battery water tank 131 to the surrounding of the battery pack 133 to absorb the heat generated by the battery. The battery pack 133 is a battery unit installed on the vehicle for storing energy. The battery pack 133 can be composed of a plurality of battery cells connected in series. These battery cells will generate a certain amount of heat when working, which needs to be cooled by cooling water to ensure the normal operation of the battery and prolong the life of the battery.

[0091] In some embodiments, the battery water tank 131, the battery water pump 132, and the battery pack 133 are connected in series between the first end of the battery thermal management water circuit 13 and the second end of the battery thermal management water circuit 13. The first end of the battery thermal management water circuit 13 is connected to the first end of the plate heat exchanger 11 through the defrosting water tank 123 and the defrosting water pump 124.

[0092] Specifically, when the battery generates more heat and has a cooling demand, the water in the defrosting water tank 123 is pressurized by the defrosting water pump 124 and flows through the plate heat exchanger 11, and then flows into the battery thermal management water circuit 13. The cooling water flows through the battery water tank 131, and then is pressurized by the battery water pump 132, and then pushes the cooling water to flow through the battery pack 133 to absorb the heat generated by the battery. Then the cooling water that has absorbed the heat flows back to the defrosting water tank 123 from the battery thermal management water circuit 13, thereby achieving the cooling effect of the battery. This design can effectively control the temperature of the battery pack 133, ensuring that it does not overheat during operation, thereby improving the working efficiency and stability of the battery pack 133.

[0093] In some embodiments, the design of the battery water tank 131 and the battery water pump 132 should take into account the layout and space limitations of the vehicle to ensure stable operation of the system. The selection and installation of the battery pack 133 also need to be reasonably arranged and configured according to the power demand and design requirements of the vehicle.

[0094] In some embodiments, according to the battery thermal management demand and the driver area cooling demand, by controlling the working state of the first switching unit 122 and the second switching unit 155, various cooling modes of the battery and the driver area can be realized.

[0095] In some embodiments, Figure 4 is a schematic diagram of a battery-only cooling mode of the thermal management system 1 according to an embodiment of the present disclosure, as shown in Figure 4, when the battery has a cooling demand and the driver area has no cooling demand, the second switching unit 155 is controlled to make the second end of the battery thermal management water circuit 13 communicate with the second end of the plate heat exchanger 11, and the first switching unit 122 is controlled to make the cooling water flowing through the driver area not pass through the first heat exchanger 121 but flow back to the defrosting water tank 123.

[0096] Specifically, the thick black line in FIG. 4 represents the water circulation route of the battery refrigeration alone, that is, the cooling water in the defrosting water tank 123 is pressurized by the defrosting water pump 124 and flows through the plate heat exchanger 11, and the passenger area air conditioning system 20 exchanges heat with the plate heat exchanger 11, so that the temperature of the cooling water is reduced. Then the cooling water is branched, one way flows through the first three-way valve 1221. By controlling the working state of the first three-way valve 1221 (that is, controlling the second valve port and the third valve port of the first three-way valve 1221 to communicate), the cooling water flowing through the driver area does not pass through the first heat exchanger 121 and returns to the defrosting water tank 123. The other way flows through the second three-way valve 15, by controlling the working state of the second three-way valve 15 (that is, controlling the second valve port and the first valve port of the second three-way valve 15 to communicate), the second end of the battery thermal management water circuit 13 is in communication with the second end of the plate heat exchanger 11, and the cooling liquid such as cooling water can flow from the second end of the plate heat exchanger 11 to the second end of the battery thermal management water circuit 13. Then the cooling water flows through the battery water tank 131, and is pressurized by the battery water pump 132, and then flows through the battery pack 133. After passing through the battery pack 133, the cooling water can effectively absorb the heat generated by the battery, and transfer the cooling water with heat back to the defrosting water tank 123, thereby achieving refrigeration of the battery.

[0097] In some embodiments, FIG. 5 is a schematic diagram of the battery refrigeration coupled with the driver area refrigeration mode according to an embodiment of the present disclosure. As shown in FIG. 5, when the battery has a refrigeration requirement and the driver area has a refrigeration requirement, the second switching unit 155 is controlled to make the second end of the battery thermal management water circuit 13 in communication with the second end of the plate heat exchanger 11 and make the first end of the battery thermal management water circuit 13 in communication with the second end of the battery thermal management water circuit 13 and the second end of the plate heat exchanger 11, and the first switching unit 122 is controlled to make the first end of the first heat exchanger 121 in communication with the second end of the plate heat exchanger 11.

[0098] Specifically, the thick gray line in FIG. 5 represents the water circulation route of the driver area refrigeration, that is, the cooling water in the defrosting water tank 123 is pressurized by the defrosting water pump 124 and flows through the plate heat exchanger 11, and the passenger area air conditioning system 20 exchanges heat with the plate heat exchanger 11, so that the temperature of the cooling water is reduced. Then the cooling water is branched, one way flows through the first three-way valve 1221; by controlling the working state of the first three-way valve 1221 (that is, controlling the first valve port and the second valve port of the first three-way valve 1221 to communicate), the first end of the first heat exchanger 121 is in communication with the second end of the plate heat exchanger 11. Therefore, the cooling water can flow from the second end of the plate heat exchanger 11 into the first heat exchanger 121, and the air blower 127 inhales the air in the driver area of the vehicle and exchanges heat with the first heat exchanger 121, and then blows out the cold air. After exchanging heat through the first heat exchanger 121, the cooling water flows out from the second end of the first heat exchanger 121 and returns to the defrosting water tank 123, thereby achieving the refrigeration effect on the driver area of the vehicle.

[0099] At the same time, the black thick line in FIG. 5 represents the water circulation route of battery refrigeration, that is, another flow of cooling water flows through the second three-way valve 15, and by controlling the working state of the second three-way valve 15 (that is, controlling the second valve port of the second three-way valve 15 to communicate with the first valve port), the second end of the battery thermal management water route 13 is communicated with the second end of the plate heat exchanger 11, and the cooling water can flow from the second end of the plate heat exchanger 11 to the second end of the battery thermal management water route 13. Then flow through the battery water tank 131, and then pressurized by the battery water pump 132, flow through the battery pack 133. After passing through the battery pack 133, the cooling water temperature rises, and then is branched again, part of the flow returns to the second three-way valve 15 and mixes with the cooling water transferred from the plate heat exchanger 11. By controlling the valve opening of the second three-way valve 15 to adjust the flow ratio of the two, and then adjust the temperature of the mixed water, so as to meet the difference between the refrigeration capacity of the driver area and the refrigeration capacity of the battery under different working conditions, and the remaining flow returns to the defrosting water tank 123, thereby realizing the refrigeration of the vehicle driver area and the battery.

[0100] In some embodiments, as shown in FIG. 3, the heat exchange module 10 further includes an electric heating water route 14 of the passenger area. The electric heating water route 14 is selectively communicated with the battery thermal management water route 13, that is, the electric heating water route 14 can be communicated with the battery thermal management water route 13, or the electric heating water route 14 can not be communicated with the battery thermal management water route 13, and whether the two are communicated can be selected according to the battery thermal management demand. For example, when there is a heating demand for the battery, the electric heating water route 14 can be communicated with the battery thermal management water route 13 and provide heating for the battery.

[0101] In some embodiments, the electric heating water route 14 includes a third switching unit 1455. The third switching unit 1455 is an important component in the electric heating water route 14, which can be realized by one component or a combination of multiple components. The third switching unit 1455 is connected with the electric heating water route 14 and the battery thermal management water route 13 respectively, and is used to control the communication state of the electric heating water route 14 and the battery thermal management water route 13.

[0102] Specifically, when the battery needs to be heated, by controlling the working state of the third switching unit 1455, the electric heating water route 14 is communicated with the battery thermal management water route 13, and the heated cooling water is allowed to flow from the electric heating water route 14 into the battery thermal management water route 13 to realize the heating of the battery. When the battery does not need to be heated, by controlling the working state of the third switching unit 1455, the electric heating water route 14 is cut off from the battery thermal management water route 13, and the heated cooling water is prevented from flowing from the electric heating water route 14 into the battery thermal management water route 13, thereby maintaining the temperature of the battery and ensuring that it is within the appropriate working range.

[0103] In some embodiments, the control mode of the third switching unit 1455 can adopt electronic control or mechanical control to accurately adjust the battery temperature and the passenger area temperature according to system requirements.

[0104] As shown in FIG. 3, the electric heating water circuit 14 includes a heating water tank 141, a heating water pump 142, an electric heating element 143, and a second heat exchanger 144. The heating water tank 141 is a container for storing cooling water, which can be located at a suitable position inside the vehicle. It can contain enough water to meet the heating system requirements and is connected to other components through connecting pipes. The heating water pump 142 can pump cooling water out of the heating water tank 141 and deliver it to the electric heating element 143 through pipes. The heating water pump 142 can be driven by an electric motor and can provide sufficient pressure and flow to ensure the flow of cooling water.

[0105] In some embodiments, the electric heating element 143 can be a PTC electric heating element 143, which can convert electrical energy into heat energy to warm up the cooling water. The electric heating element 143 can be controlled as needed to adjust the heating power and heating time to meet different heating requirements.

[0106] In some embodiments, the second heat exchanger 144 can be designed as a radiator to transfer the heat carried by the heated cooling water to the air. In the passenger area of the vehicle, many water pipes can be arranged, and the surface of the water pipes can be designed in a fin shape to increase the surface area for heat dissipation. An external fan can also be installed to enhance the heat dissipation effect by driving the fan. The fan can blow air over the surface of the second heat exchanger 144 to carry away the heat, and then transfer the hot air to the entire passenger area, thereby achieving the warming of the passenger area and meeting the heating requirements of the passenger area.

[0107] In some embodiments, the heating water tank 141, the heating water pump 142, and the second heat exchanger 144 are connected to form a water circuit, and the electric heating element 143 is used to heat the water circuit. Specifically, the cooling water is pumped from the heating water tank 141 to the electric heating element 143 for heating, then releases heat through the second heat exchanger 144, and finally flows back to the heating water tank 141 to achieve a circulating heating effect. Therefore, this water circuit can make the heated water circulate in the electric heating water circuit 14, thereby achieving heat transfer and heating effect.

[0108] In some embodiments, the first end of the battery thermal management water circuit 13 is also in communication with the heating water tank 141. Through this connection, heated cooling water in the heating water tank 141 can be delivered to the battery thermal management water circuit 13 for battery heating. After the cooling water is heated in the battery thermal management water circuit 13, it can flow back to the heating water tank 141 through the first end of the battery thermal management water circuit 13 to complete the cycle. Such a design can effectively meet the heating needs of the battery and improve the performance and reliability of the battery in cold environments.

[0109] As shown in FIG. 3, the third switching unit 1455 includes a third three-way valve 145, which is also a valve device and includes three valve ports. The first valve port of the third three-way valve 145 is connected with the battery thermal management water circuit 13, the second valve port of the third three-way valve 145 is connected with the input end of the second heat exchanger 144, and the third valve port of the third three-way valve 145 is connected with the water circuit at the electric heating element 143. The third three-way valve 145 controls the communication state between the battery thermal management water circuit 13 and the electric heating water circuit 14 and controls the communication state between the second heat exchanger 144 and the electric heating element 143 according to the system control signal, so as to realize heating control of the battery and the passenger area.

[0110] Specifically, when the battery needs to be heated, the cooling water in the heating water tank 141 is pressurized by the heating water pump 142 and then flows through the electric heating element 143 for heating. The cooling water is heated by the electric heating element 143, so that the temperature of the cooling water rises. Then, according to the system control signal, the third valve port of the third three-way valve 145 is controlled to communicate with the first valve port, so that the heated cooling water can flow from the water circuit of the electric heating element 143 to the battery thermal management water circuit 13. Then, the heated cooling water is pressurized by the battery water pump 132 and then flows through the battery pack 133, so that the temperature of the battery pack 133 rises. Finally, the heated cooling water flows back to the heating water tank 141 from the first end of the battery thermal management water circuit 13, thereby realizing the heating process of the battery. When the battery does not need to be heated, the third valve port of the third three-way valve 145 can be controlled to close the communication with the first valve port, so as to cut off the connection between the electric heating water circuit 14 and the battery thermal management water circuit 13, preventing the heated cooling water from flowing through the battery thermal management water circuit 13, thereby no longer heating the battery.

[0111] In addition, when the passenger area needs to be heated, the cooling water of the heating water tank 141 is pressurized by the heating water pump 142, then flows through the electric heating element 143 to be heated, and the cooling water is heated by the electric heating element 143 to increase the temperature of the cooling water. Then, according to the control signal of the system, the third valve port of the third three-way valve 145 is controlled to communicate with the second valve port, so that the heated cooling water can flow from the electric heating element 143 to the second heat exchanger 144, and the second heat exchanger 144 can transfer the heat carried by the heated cooling water to the air. Then the hot air is transferred to the entire passenger area, thereby realizing the temperature rise of the entire passenger area. Finally, the cooling water will flow back to the heating water tank 141 to realize the heating effect of the passenger area. When the passenger area does not need to be heated, the third valve port of the third three-way valve 145 can be controlled to close the communication with the second valve port, so as to cut off the connection between the electric heating element 143 and the second heat exchanger 144, prevent the heated cooling water from flowing through the second heat exchanger 144 to dissipate heat, and thus the passenger area is no longer heated.

[0112] In some embodiments, the control of the third three-way valve 145 can adopt electronic control or other appropriate control mode to adjust the flow direction and flow rate of the cooling water according to the system requirements and design requirements, so as to realize the precise control of the battery temperature and the passenger area temperature.

[0113] In other embodiments, the third switching unit 1455 can also be realized by a plurality of switch valves, for example, the third switching unit 1455 can include a fifth switch valve 25 and a sixth switch valve 26.

[0114] Wherein the first end of the fifth switch valve 25 is connected with the waterway at the electric heating element 143, and the second end of the fifth switch valve 25 is connected with the input end of the second heat exchanger 144. The first end of the sixth switch valve 26 is connected with the waterway at the electric heating element 143, and the second end of the sixth switch valve 26 is connected with the battery thermal management waterway 13.

[0115] Specifically, when the battery needs to be heated, the cooling water in the heating water tank 141 is pressurized by the heating water pump 142, then flows through the electric heating element 143 to be heated, and the temperature of the cooling water is raised by the electric heating element 143. Then, according to the control signal of the system, the sixth switch valve 26 is opened, and the heated cooling water can flow from the water path of the electric heating element 143 to the battery thermal management water path 13. Then, the heated cooling water is pressurized by the battery water pump 132, and then flows through the battery pack 133, so that the temperature of the battery pack 133 is raised. Finally, the cooling water flows back from the first end of the battery thermal management water path 13 to the heating water tank 141. Thus, the heating process of the battery is realized. When the battery does not need to be heated, the sixth switch valve 26 can be controlled to be closed to cut off the connection between the electric heating water path 14 and the battery thermal management water path 13, so that the heated cooling water does not flow through the battery thermal management water path 13, and the battery is not heated any more.

[0116] In addition, when the passenger area needs to be heated, the cooling water in the heating water tank 141 is pressurized by the heating water pump 142, then flows through the electric heating element 143 to be heated, and the temperature of the cooling water is raised by the electric heating element 143. Then, according to the control signal of the system, the fifth switch valve 25 is opened, and the heated cooling water can flow from the electric heating element 143 to the second heat exchanger 144, and the second heat exchanger 144 can transfer the heat carried by the heated cooling water to the air. Then, the hot air is transferred to the entire passenger area, so that the temperature of the passenger area of the entire vehicle is raised. Finally, the cooling water flows back to the heating water tank 141 to realize the heating effect of the passenger area. When the passenger area does not need to be heated, the fifth switch valve 25 can be controlled to be closed to cut off the connection between the electric heating element 143 and the second heat exchanger 144, so that the heated cooling water does not flow through the second heat exchanger 144 to be cooled, and the passenger area is not heated any more.

[0117] In some embodiments, the control of the fifth switch valve 25 and the sixth switch valve 26 can adopt electronic control or other appropriate control mode to adjust the flow direction and flow rate of the cooling water according to the system requirements and design requirements, so as to realize the accurate control of the temperature of the battery and the temperature of the passenger area.

[0118] In some embodiments, the battery thermal management water path 13 further comprises a fourth switching unit 1344, which is an important component of the battery thermal management water path 13 and can be realized by one component or a combination of multiple components. The fourth switching unit 1344 is connected with the battery thermal management water path 13 and the third switching unit 1455 respectively, and is used to control the communication state between the battery thermal management water path 13 and the electric heating water path 14.

[0119] Specifically, when the battery needs to be heated, the fourth switching unit 1344 is controlled to connect the electric heating water circuit 14 with the battery thermal management water circuit 13, allowing the heated cooling water to flow from the electric heating water circuit 14 to the battery thermal management water circuit 13, so as to heat the battery. When the battery does not need to be heated, the fourth switching unit 1344 is controlled to disconnect the electric heating water circuit 14 from the battery thermal management water circuit 13, preventing the heated cooling water from flowing from the electric heating water circuit 14 to the battery thermal management water circuit 13, so as to maintain the temperature of the battery within the appropriate working range.

[0120] In some embodiments, the fourth switching unit 1344 can be controlled by electronic control or mechanical control to accurately adjust the temperature of the battery according to the system requirements.

[0121] As shown in FIG. 3, the fourth switching unit 1344 includes a fourth three-way valve 134, which is also a valve device and includes three valve ports. The first valve port of the fourth three-way valve 134 is connected with the third switching unit 1455, the second valve port of the fourth three-way valve 134 is connected with the battery water tank 131, and the third valve port of the fourth three-way valve 134 is connected with the battery water pump 132. The fourth three-way valve 134 is used to control the connection state of the battery thermal management water circuit 13 and the electric heating water circuit 14 according to the system control signal, so as to achieve the heating control of the battery.

[0122] Specifically, when the battery needs to be heated, the cooling water in the heating water tank 141 is pressurized by the heating water pump 142 and then flows through the electric heating element 143 to be heated. The electric heating element 143 heats the cooling water, so that the temperature of the cooling water rises. Then, according to the system control signal, the third valve port of the third three-way valve 145 is controlled to be connected with the first valve port, so that the heated cooling water can flow from the water circuit of the electric heating element 143 to the battery thermal management water circuit 13. Then, the first valve port of the fourth three-way valve 134 is controlled to be connected with the third valve port, so that the heated cooling water flows into the battery water pump 132. After being pressurized by the battery water pump 132, the heated cooling water flows through the battery pack 133, so that the temperature of the battery pack 133 rises. Finally, the heated cooling water flows back from the first end of the battery thermal management water circuit 13 to the heating water tank 141, so as to achieve the heating process of the battery. When the battery does not need to be heated, the third valve port of the third three-way valve 145 can be controlled to be closed with the first valve port, or the first valve port of the fourth three-way valve 134 can be controlled to be closed with the third valve port, so as to prevent the heated cooling water from flowing through the battery thermal management water circuit 13, thereby stopping the heating of the battery.

[0123] In some embodiments, the fourth three-way valve 134 can be controlled by electronic control or other appropriate control methods to adjust the flow direction and flow rate of the cooling water according to the system requirements and design requirements, so as to accurately control the temperature of the battery.

[0124] In other embodiments, the fourth switching unit 1344 can also be implemented by multiple switching valves, for example, the fourth switching unit 1344 can include a seventh switching valve 27 and an eighth switching valve 28.

[0125] Wherein the first end of the seventh switching valve 27 is connected with the battery water tank 131, and the second end of the seventh switching valve 27 is connected with the battery water pump 132. The first end of the eighth switching valve 28 is connected with the third switching unit 1455, and the second end of the eighth switching valve 28 is connected with the battery water pump 132.

[0126] Specifically, when the battery needs to be heated, the cooling water of the heating water tank 141 is pressurized by the heating water pump 142, then flows through the electric heating element 143 to be heated, and the cooling water is heated by the electric heating element 143 to make the temperature of the cooling water rise. Then, according to the control signal of the system, the eighth switching valve 28 is opened and the seventh switching valve 27 is closed, so that the heated cooling water can flow from the third switching unit 1455 to the battery water pump 132 in the battery thermal management water circuit 13, and then pressurized by the battery water pump 132, and flows through the battery pack 133 to make the temperature of the battery pack 133 rise. Finally, the cooling water flows back to the heating water tank 141 from the first end of the battery thermal management water circuit 13. Thus, the heating process of the battery is realized. When the battery does not need to be heated, according to the control signal of the system, the seventh switching valve 27 can be opened and the eighth switching valve 28 can be closed, so that the heated cooling water directly flows into the battery water tank 131, preventing the heated cooling water from flowing through the battery water pump 132 and the battery pack 133, so that the battery cannot be heated.

[0127] In some embodiments, the control of the seventh switching valve 27 and the eighth switching valve 28 can adopt electronic control or other appropriate control mode to adjust the flow direction and flow rate of the cooling water according to the system requirements and design requirements, so as to realize the precise control of the battery temperature.

[0128] In some embodiments, according to the battery thermal management requirements and the passenger area heating requirements, by controlling the working state of the third switching unit 1455 and the fourth switching unit 1344, various heating modes of the battery and the passenger area can be realized.

[0129] In some embodiments, FIG. 6 is a schematic diagram of a battery-only heating mode of the thermal management system 1 according to an embodiment of the present disclosure, as shown in FIG. 6, when the battery has heating requirements and the passenger area has no heating requirements, the third switching unit 1455 and the fourth switching unit 1344 are controlled to make the battery thermal management water circuit 13 communicate with the electric heating water circuit 14.

[0130] Specifically, the black thick line in FIG. 6 represents the water circulation route of battery heating, that is, the cooling water of the heating water tank 141 is pressurized by the heating water pump 142, then flows through the electric heating element 143 to be heated, and the cooling water is heated by the electric heating element 143, so that the temperature of the cooling water rises. Then, according to the control signal of the system, the working state of the third three-way valve 145 is controlled (that is, the third valve port and the first valve port of the third three-way valve 145 are controlled to be communicated, and the second valve port is controlled to be closed), so that the heated cooling water flows from the water path of the electric heating element 143 to the fourth three-way valve 134. Then, according to the control signal of the system, the working state of the fourth three-way valve 134 is controlled (that is, the first valve port and the third valve port of the fourth three-way valve 134 are controlled to be communicated, and the second valve port is controlled to be closed), so that the heated cooling water flows into the battery water pump 132. After being pressurized by the battery water pump 132, it flows through the battery pack 133, so that the temperature of the battery pack 133 rises. Finally, the cooling water flows back to the heating water tank 141 from the first end of the battery thermal management water path 13, thereby realizing the heating process of the battery.

[0131] In some embodiments, FIG. 7 is a schematic diagram of a passenger area separate heating mode of the thermal management system 1 according to an embodiment of the present disclosure. As shown in FIG. 7, when there is no heating demand for the battery and there is a heating demand for the passenger area, the third switching unit 1455 and the fourth switching unit 1344 are controlled to cut off the communication between the battery thermal management water path 13 and the electric heating water path 14, and the electric heating water path 14 forms a heating loop.

[0132] Specifically, the black thick line in FIG. 6 represents the water circulation route of battery heating, that is, the cooling water of the heating water tank 141 is pressurized by the heating water pump 142, then flows through the electric heating element 143 to be heated, and the cooling water is heated by the electric heating element 143, so that the temperature of the cooling water rises. Then, according to the control signal of the system, the working state of the third three-way valve 145 is controlled (that is, the third valve port and the second valve port of the third three-way valve 145 are controlled to be communicated, and the first valve port is controlled to be closed), so that the heated cooling water can flow from the electric heating element 143 to the second heat exchanger 144, and the second heat exchanger 144 can transfer the heat carried by the heated cooling water to the air. Then, the hot air is transferred to the entire passenger area by the fan, thereby realizing the temperature rise of the passenger area of the entire vehicle. Finally, the cooling water will flow back to the heating water tank 141 to realize the heating effect on the passenger area.

[0133] In some embodiments, Fig. 8 is a schematic diagram of the battery heating coupled with the passenger area heating mode according to one embodiment of the present disclosure. As shown in Fig. 8, when there is a heating demand for both the battery and the passenger area, the fourth switching unit 1344 and the third switching unit 1455 are controlled to make the battery thermal management water circuit 13 communicate with the electric heating water circuit 14, and the second switching unit 155 and the fourth switching unit 1344 are controlled to make the battery thermal management water circuit 13 form a battery heating loop, and the third switching unit 1455 is controlled to make the electric heating water circuit 14 form a passenger area heating loop.

[0134] Specifically, the black thick line in Fig. 8 represents the water circulation route of battery heating, i.e., the cooling water of the heating water tank 141 is pressurized by the heating water pump 142, flows through the electric heating element 143 to be heated, and the electric heating element 143 heats the cooling water so that the temperature of the cooling water rises. After the cooling water is heated by the electric heating element 143, the working state of the third three-way valve 145 can be controlled according to the control signal of the system to make the cooling water branch. That is, the third valve port and the first valve port of the third three-way valve 145 are controlled to communicate, so that the heated cooling water branches out and can flow from the water circuit of the electric heating element 143 to the fourth three-way valve 134. At the same time, in order to more accurately regulate the temperature of the battery, the second valve port and the first valve port of the fourth three-way valve 134 can also be controlled to communicate, so that the cooling water of the battery water tank 131 mixes with the cooling water flowing through the electric heating element 143 through the fourth three-way valve 134, the flow of the mixed cooling water increases and the temperature decreases. Then, according to the control signal of the system, the first valve port and the third valve port of the fourth three-way valve 134 can be controlled to communicate, so that the mixed cooling water flows into the battery thermal management water circuit 13. After being pressurized by the battery water pump 132, it flows through the battery pack 133, so that the temperature of the battery pack 133 slowly rises. Finally, the cooling water returns to the heating water tank 141 from the first end of the battery thermal management water circuit 13, thereby achieving heating of the battery.

[0135] In addition, the gray thick line in Fig. 8 represents the water circulation route of passenger area heating, i.e., by controlling the third valve port and the second valve port of the third three-way valve 145 to communicate, another route of cooling water can flow from the electric heating element 143 to the second heat exchanger 144, and the second heat exchanger 144 can transfer the heat carried by the heated cooling water to the air. Then, the hot air is transferred to the entire passenger area by the fan, thereby achieving temperature rise of the entire passenger area. Finally, the cooling water returns to the heating water tank 141 to achieve the heating effect of the passenger area.

[0136] Therefore, by coupling the electric heating water circuit 14 of the passenger area with the battery thermal management water circuit 13, one electric heating element 143 can be shared, thereby reducing the number of electric heating elements 143 and further reducing the volume and weight of the thermal management system 1.

[0137] In some embodiments, as shown in FIG. 11, the heat exchange module 10 further comprises a controller 2. The controller 2 is connected with the first switching unit 122, the second switching unit 155, the third switching unit 1455 and the fourth switching unit 1344, respectively, for controlling the switching states of the first switching unit 122, the second switching unit 155, the third switching unit 1455 and the fourth switching unit 1344 according to the driver area cooling demand, the battery thermal management demand and the passenger area heating demand.

[0138] In some embodiments, the controller 2 can execute specific control algorithms, such as PID control, fuzzy logic control or rule-based control, etc., to determine the switching states of the switching units, so as to achieve intelligent adjustment of the temperatures of the various areas of the vehicle. In addition, in order to improve the robustness and stability of the system, real-time monitoring and feedback control in combination with sensor data are also required.

[0139] In some embodiments, the driver area air conditioning system 12 further comprises a first temperature sensor 126 for detecting the temperature of the cooling liquid output by the plate heat exchanger 11. The controller 2 is connected with the first temperature sensor 126, for adjusting the opening degree of the first switching unit 122 according to the temperature of the cooling liquid output by the plate heat exchanger 11 when there is a cooling demand in the driver area.

[0140] Specifically, the controller 2 can adopt corresponding control strategies according to the preset temperature set value and the real-time monitoring of the cooling liquid temperature information by the first temperature sensor 126. For example, when the first temperature sensor 126 detects that the temperature of the cooling liquid output by the plate heat exchanger 11 is close to the set value, the controller 2 can increase the opening degree of the first valve port and the second valve port of the first three-way valve 1221, so as to increase the flow of the cooling liquid output by the plate heat exchanger 11 into the first heat exchanger 121, thereby enhancing the cooling effect; when the first temperature sensor 126 detects that the temperature of the cooling liquid output by the plate heat exchanger 11 is greatly different from the set value, the controller 2 can reduce the opening degree of the first valve port and the second valve port of the first three-way valve 1221, so as to reduce the flow of the cooling liquid output by the plate heat exchanger 11 into the first heat exchanger 121, thereby avoiding poor cooling effect or excessive cooling in the driver area.

[0141] In some embodiments, the battery thermal management water circuit 13 further comprises a second temperature sensor 135 for detecting the temperature of the cooling liquid of the battery thermal management water circuit 13. The controller 2 is further connected with the second temperature sensor 135, for adjusting at least one of the opening degree of the second switching unit 155, the opening degree of the fourth switching unit 1344, the rotation speed of the battery water pump 132, the heating power of the electric heating element 143 and the rotation speed of the heating water pump 142 according to the battery thermal management demand and the temperature of the cooling liquid of the battery thermal management water circuit 13.

[0142] Specifically, the controller 2 can take corresponding control strategies according to the preset temperature set value and the cooling liquid temperature information of the battery thermal management water circuit 13 monitored by the second temperature sensor 135 in real time. For example, when the battery pack 133 needs to be heated, the controller 2 can increase the opening degree of the third valve port and the first valve port of the third three-way valve 145, or increase the opening degree of the first valve port and the third valve port of the fourth three-way valve 134, or also increase the rotation speed of the battery water pump 132, the heating power of the electric heating element 143, and the rotation speed of the heating water pump 142, etc., to increase the cooling liquid flow into the battery thermal management water circuit 13 and increase the temperature of the cooling liquid, so as to heat the battery pack 133 and make the battery pack 133 be at a suitable working temperature.

[0143] In some embodiments, the electric heating water circuit 14 further comprises a third temperature sensor 146 for detecting the cooling liquid temperature of the electric heating water circuit 14. The controller 2 is also connected with the third temperature sensor 146, for adjusting the opening degree of the third switching unit 1455 and the rotation speed of the heating water pump 142 according to the cooling liquid temperature of the electric heating water circuit 14 when there is a heating demand in the passenger area.

[0144] Specifically, the controller 2 can also take corresponding control strategies according to the preset temperature set value and the cooling liquid temperature information of the electric heating water circuit 14 monitored by the third temperature sensor 146 in real time. For example, when there is a heating demand in the passenger area, the controller 2 can increase the opening degree of the third valve port and the second valve port of the third three-way valve 145, or increase the rotation speed of the heating water pump 142, to increase the cooling liquid flow of the electric heating water circuit 14, so as to better heat the passenger area and make the passenger area be at a comfortable temperature.

[0148] In some embodiments, the passenger zone air conditioning system 20 is a system for controlling refrigeration of the vehicle passenger zone, which can include components such as an air conditioning compressor, a condenser, an evaporator, a fan, a controller 2, and a sensor. When the passenger zone needs refrigeration, the passenger zone air conditioning system 20 can absorb heat inside the passenger zone by circulating refrigerant and discharge it outside the vehicle, thereby reducing the temperature of the passenger zone.

This design not only enables the passenger zone air conditioning system 20 to meet the refrigeration needs of different areas of the vehicle, but also enables the refrigeration of the driver zone through the connection with the heat exchange module 10, without the need for an additional independent driver zone air conditioning system 12. This design reduces the number of parts, reduces the overall volume and weight of the system, simplifies the system structure, thereby reducing manufacturing costs and improving the market competitiveness of the vehicle.
