DETAILED DESCRIPTION

[0045] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0046] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present application described can be implemented in an order other than those illustrated or described herein.

[0047] In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or modules is not necessarily limited to those steps or modules explicitly listed, but may include other steps or modules not explicitly listed or inherent to these processes, methods, products, or apparatuses.

[0048] For ease of understanding and explanation, the following Figures 1 to 8 The heat exchange assembly provided in the embodiments of the present application and the battery pack, thermal management system, and vehicle having the same are described in detail.

[0049] Please refer to Figure 1, which is a schematic diagram of the structure of a heat exchange component provided in an embodiment of the present application. The heat exchange component 1 includes a substrate 11 and at least two heat exchange mechanisms 12 arranged on the substrate 11, and the at least two heat exchange mechanisms 12 are respectively located on different sides of the substrate 11 and can perform heat exchange with their respective corresponding heat exchange objects. The advantage of such a setting is that by arranging the heat exchange mechanisms 12 on different sides of the substrate 11, the number of interfaces can be reduced, modularization and miniaturization are facilitated, the space utilization rate is effectively improved, the manufacturing cost is reduced, and the application range is wide.

[0050] For example, in the embodiment of the present application, the heat exchange mechanism 12 may include a power distribution assembly liquid cooling component 121 and a heat pump heat absorption direct cooling component 122. Figure 2 and Figure 3 As shown, the power distribution assembly liquid cooling part 121 and the heat pump heat absorption direct cooling part 122 are respectively located on both sides of the substrate 11, wherein the power distribution assembly liquid cooling part 121 is far away from the substrate 11 and is suitable for being provided with the power distribution assembly a, and the heat pump heat absorption direct cooling part 122 is close to the power distribution assembly liquid cooling part 121, that is, the power distribution assembly liquid cooling part 121 and the heat pump heat absorption direct cooling part 122 share the same substrate 11. Optionally, as Figure 4 As shown, in the embodiment of the present application, the power distribution assembly liquid cooling component 121 and the heat pump heat absorption direct cooling component 122 can both be located in the first area of ​​the substrate 11, and the power distribution assembly liquid cooling component 121 is located on the first side of the first area, and the heat pump heat absorption direct cooling component 122 is located on the second side of the first area, for example, the first area is the power distribution assembly area. The advantage of such a setting is that the power distribution assembly liquid cooling component 121 and the heat pump heat absorption direct cooling component 122 can directly exchange heat at the substrate 11 without the need for additional piping, which greatly reduces the heat transfer path, improves the heat exchange efficiency, and also reduces the number of thermal management components used, which can reduce costs; and, by setting the power distribution assembly a of the entire vehicle on the substrate 11, the vehicle body space can be greatly saved, and unified management and maintenance are convenient. At the same time, the power distribution assembly liquid cooling component 121 can efficiently conduct heat to the power distribution assembly a, ensuring that the power distribution assembly a operates well.

[0051] Furthermore, for example, in the embodiment of the present application, the power distribution assembly liquid cooling component 121 may include a power distribution assembly liquid cooling channel b1 and a power distribution assembly liquid cooling connector b2 respectively arranged at the channel inlet and the channel outlet of the power distribution assembly liquid cooling channel b1. That is to say, in actual use, the coolant can enter the power distribution assembly liquid cooling flow plate b1 through the power distribution assembly liquid cooling connector at the channel inlet, and flow out of the power distribution assembly liquid cooling channel b1 from the power distribution assembly liquid cooling connector at the channel outlet.

[0052] For another example, the heat pump heat absorption direct cooling component 122 in the embodiment of the present application may include a heat pump heat absorption flow channel c1 and heat pump heat absorption direct cooling joints c2 respectively arranged at the flow channel inlet and the flow channel outlet of the heat pump heat absorption flow channel c1, that is, in actual use, the refrigerant can enter the heat pump heat absorption flow channel c1 through the heat pump heat absorption direct cooling joint at the flow channel inlet, and flow out of the heat pump heat absorption flow channel c1 from the heat pump heat absorption direct cooling joint at the flow channel outlet. In the embodiment of the present application, the range of the width A1 of the heat pump heat absorption flow channel c1 can be 0<A1≤15mm; or, the range of the spacing B1 between adjacent heat pump heat absorption flow channels c1 can be B1≥4mm; or, the range of the width A1 of the heat pump heat absorption flow channel c1 is 0<A1≤15mm, and the range of the spacing B1 between adjacent flow channels is B1≥4mm, so that it can be adjusted according to actual use needs, with strong flexibility.

[0053] For example, in ② the embodiment of the present application, the heat exchange mechanism 12 may further include a battery cell direct cooling component 123, which is located on one side of the substrate 11, and the other side of the substrate 11 is suitable for being provided with a battery cell d, thereby facilitating rapid heat exchange between the battery cell direct cooling component 123 and the battery cell d, thereby improving heat exchange efficiency.

[0054] Furthermore, combined with Figure 2 , Figure 3 , Figure 4 As shown, for example, in the embodiment of the present application, the battery cell direct cooling component 123 is located in the second area of ​​the substrate 11, and the battery cell direct cooling component 123 and the heat pump heat absorption direct cooling component 122 are located on the same side of the substrate 11, such as the second area is the battery cell area, and the second area does not overlap with the first area.

[0055] For another example, the battery cell direct cooling member 123 in the embodiment of the present application may include a battery cell direct cooling and direct heating runner e1 and a battery cell direct cooling joint e2 respectively arranged at the runner inlet and the runner outlet of the battery cell direct cooling and direct heating runner e1, that is, in actual use, the refrigerant can enter the battery cell direct cooling and direct heating runner e1 through the battery cell direct cooling joint at the runner inlet, and flow out of the battery cell direct cooling and direct heating runner e1 from the battery cell direct cooling joint at the runner outlet. In the embodiment of the present application, the range of the width A2 of the battery cell direct cooling and direct heating runner e1 can be 0<A2≤15mm; or, the range of the spacing B2 between adjacent battery cell direct cooling and direct heating runner e1 can be B2≥4mm; or, the range of the width A2 of the battery cell direct cooling and direct heating runner e1 is 0<A2≤15mm, and the range of the spacing B2 between adjacent runners is B2≥4mm, so that both heat exchange efficiency and manufacturing cost can be taken into account.

[0056] In another example, in the case where the heat exchange mechanism 12 includes a power distribution assembly liquid cooling component 121 and a heat pump heat absorption direct cooling component 122, Figure 5As shown, in the embodiment of the present application, the battery cell direct cooling and direct heating flow channel e1 and the heat pump heat absorption flow channel c1 in the heat pump heat absorption and direct cooling part 122 are in the same plane, and the battery cell direct cooling joint e2 is integrated with the heat pump heat absorption and direct cooling joint c2 on the heat pump heat absorption flow channel c1. In other words, the battery cell direct cooling and direct heating flow channel e1 and the heat pump heat absorption flow channel c1 can be integrated on the same stamping plate and brazed with their corresponding joints, thereby effectively reducing the number of parts and components and greatly improving space utilization.

[0057] Further, as Figure 5 As shown, in the embodiment of the present application, a heat insulating member f can also be provided between the battery cell direct cooling and direct heating flow channel e1 and the heat pump heat absorption flow channel c1. For example, the heat insulating member f is a false flow channel, that is, a flow channel that cannot flow refrigerant. The advantage of such a setting is that it can play a heat insulating role under low-temperature heating conditions, avoiding a large difference in refrigerant temperature in the battery cell direct cooling and direct heating flow channel e1 and the heat pump heat absorption flow channel c1, which affects the heat exchange effect at the junction between the two.

[0058] The heat exchange component provided in the embodiment of the present application, by arranging heat exchange mechanisms on different sides of a substrate, and utilizing the heat exchange mechanisms to perform efficient heat exchange with the respective corresponding heat exchange objects, can not only reduce the number of interfaces, facilitate modularization and miniaturization, greatly improve space utilization, but also reduce manufacturing costs, meet diverse usage requirements, and have a wide range of applications.

[0059] As another aspect, the present application embodiment provides a battery pack. Figure 6 As shown, it is a schematic diagram of the structure of a battery pack provided in an embodiment of the present application. The battery pack 2 may include Figures 1 to 5 The heat exchange component 1 of the corresponding embodiment.

[0060] For example, in the embodiment of the present application, the battery pack 2 may also include a power distribution assembly a, which is arranged on the power distribution assembly liquid cooling part 121 of the heat exchange mechanism 12 and away from the substrate 11, and the power distribution assembly a includes but is not limited to at least one of the compressor module a1, the battery pack power distribution module a2, the power module a3 and the electronic control module a4, that is, the power distribution module of the whole vehicle can be placed in the battery pack 2, thereby greatly improving the utilization rate of the vehicle body space, while reducing the number of parts and reducing the manufacturing cost. For another example, in the embodiment of the present application, the battery pack 2 may also include a battery cell d arranged on one side of the substrate 11, and a battery cell direct cooling part 123 of the heat exchange mechanism 12 is provided on the other side of the substrate 11, thereby facilitating efficient heat exchange between the battery cell direct cooling part 123 and the battery cell d.

[0061] It should be noted that, for the description of the same contents in this embodiment as those in other embodiments, reference can be made to the description in other embodiments and will not be repeated here.

[0062] The battery pack provided in the embodiment of the present application can reduce the number of interfaces, facilitate modularization and miniaturization, greatly improve space utilization, reduce manufacturing costs, meet diverse usage requirements, and has a wide range of applications because the heat exchange assembly in the battery pack arranges heat exchange mechanisms on different sides of the substrate and uses the heat exchange mechanisms to perform efficient heat exchange with the corresponding heat exchange objects.

[0063] As another aspect, the present application provides a thermal management system. Figure 7 As shown, it is an example of a composition structure of a thermal management system provided in an embodiment of the present application. The thermal management system 3 may include a compressor 31, a first flow direction control mechanism 32, Figure 6 The battery pack 2, the second flow control mechanism 33, the gas-liquid separator 34, the third flow control mechanism 35, the motor 36 and the water pump 37 of the corresponding embodiment can effectively manage the thermal performance of the battery cell. For example, the first flow control mechanism 32 includes but is not limited to the first solenoid valve 321, the throttle valve 322 and the second solenoid valve 323, etc., the second flow control mechanism 33 includes but is not limited to the electronic expansion valve 331, the one-way valve 332 and the third battery valve 333, etc., and the third flow control mechanism 35 includes but is not limited to the three-way water valve 351, etc.

[0064] Among them, the first end of the compressor 31 is connected to the first end of the first flow direction control mechanism 32 (corresponding to the inlet of the first solenoid valve 321 and the inlet of the second solenoid valve 323), the second end of the first flow direction control mechanism 32 (corresponding to the outlet of the throttle valve 322) is connected to the battery cell direct cooling joint at the inlet of the flow channel on the battery cell direct cooling and direct heating flow channel e1 in the battery pack 2, the battery cell direct cooling joint at the outlet of the flow channel on the battery cell direct cooling and direct heating flow channel e1 in the battery pack 2 is connected to the first end of the second flow direction control mechanism 33 (corresponding to the inlet of the electronic expansion valve 331), the second end of the second flow direction control mechanism 33 (corresponding to the outlet of the third battery valve 333) is connected to the heat pump heat absorption direct cooling joint at the inlet of the flow channel on the heat pump heat absorption flow channel c1 in the battery pack 2, the heat pump heat absorption direct cooling joint at the outlet of the flow channel on the heat pump heat absorption flow channel c1 in the battery pack 2 is connected to the first end of the gas-liquid separator 34, and the second end of the gas-liquid separator 34 is connected to the second end of the compressor 31. The liquid cooling joint of the distribution assembly at the outlet of the liquid cooling channel b1 of the distribution assembly in the battery pack 2 is connected to the first end of the third flow direction control mechanism 35 (corresponding to the inlet of the three-way water valve 351), the second end of the third flow direction control mechanism 35 (corresponding to the first outlet of the three-way water valve 351) is connected to the first end of the motor 36, the second end of the motor 36 is connected to the first end of the water pump 37, and the second end of the water pump 37 is connected to the liquid cooling joint of the distribution assembly at the inlet of the liquid cooling channel b1 of the distribution assembly in the battery pack 2.

[0065] Further, for example, in the embodiment of the present application, the thermal management system 3 may also include a motor radiator 38, the first end of which is connected to the third end of the third flow direction control mechanism 35 (corresponding to the second outlet of the three-way water valve 351), and the second end of which is connected to the first end of the motor 36. The advantage of such a configuration is that when the refrigerant is not introduced into the heat pump heat absorption channel c1 in the cooling condition, the heat absorbed by the coolant in the liquid cooling channel b1 of the power distribution assembly can be dissipated by the circulating air in the motor radiator 38. For another example, in the embodiment of the present application, the thermal management system 3 may also include an in-vehicle condenser 39, the first end of which is connected to the third end of the first flow direction control mechanism 32 (corresponding to the outlet of the second solenoid valve 323), and the second end of which is connected to the third end of the second flow direction control mechanism 33 (corresponding to the outlet of the one-way valve 332 and the inlet of the third battery valve 333), thereby heating the passenger compartment.

[0066] It should be noted that, for the description of the same contents in this embodiment as those in other embodiments, reference can be made to the description in other embodiments and will not be repeated here.

[0067] The thermal management system provided in the embodiment of the present application can reduce the number of interfaces, facilitate modularization and miniaturization, greatly improve space utilization, reduce manufacturing costs, meet diverse usage requirements, and has a wide range of applications because the heat exchange component in the battery pack of the thermal management system arranges heat exchange mechanisms on different sides of the substrate and uses the heat exchange mechanisms to perform efficient heat exchange with the corresponding heat exchange objects.

[0068] As another aspect, the present application provides a vehicle. Figure 8 As shown, it is a structural block diagram of a vehicle provided in an embodiment of the present application. The vehicle 4 may include Figure 6 The battery pack 2 of the corresponding embodiment. For example, the vehicle 4 includes but is not limited to a pure electric vehicle (Battery Electric Vehicle, BEV) and a hybrid electric vehicle (Hybrid Electric Vehicle, HEV).

[0069] For example, the vehicle 4 is a vehicle, and combined with Figure 7 The thermal management system shown in the figure describes the thermal management process of the vehicle 4 in detail. In actual use, 1) in the heating condition of the battery cell d, the first solenoid valve 321 and the third battery valve 333 are turned on, and the second solenoid valve 323 is turned off. The high-temperature and high-pressure gaseous refrigerant output from the compressor 31 flows into the battery cell direct cooling and direct heating flow channel e1 of the battery pack 2 through the throttle valve 322 to release heat to the battery cell d. At this time, the state of the refrigerant changes from gas to liquid and flows out of the battery pack 2, that is, the battery cell area adopts the refrigerant direct cooling and direct heating method for thermal management.

[0070] After the electronic expansion valve 331, the refrigerant flows into the heat pump heat absorption channel c1 of the battery pack 2. At this time, the power distribution assembly a releases a large amount of heat during operation, and the heat is absorbed by the coolant through the power distribution assembly liquid cooling channel b1. That is, the power distribution assembly area adopts the coolant liquid cooling method for heat management, and then the heat is transferred to the refrigerant in the heat pump heat absorption channel c1 through the substrate 11. At this time, the state of the refrigerant changes from liquid to gas again, and flows out of the battery pack 2 and flows into the compressor 31 after passing through the gas-liquid separator 34. The coolant in the power distribution assembly liquid cooling channel b1 directly transfers the heat to the refrigerant in the heat pump heat absorption channel c1, then flows out of the battery pack 2, and flows into the motor 36 through the three-way water valve 351 to absorb the heat generated by the motor 36 during operation, and then returns to the battery pack 2 through the water pump 37 to continue to absorb and release heat. That is to say, the heat generated by the power distribution assembly a and the motor 36 can be absorbed by the refrigerant in the heat pump heat absorption channel c1.

[0071] 2) In the heating condition of the passenger compartment, the second solenoid valve 323 and the third battery valve 333 are turned on, the first solenoid valve 321 is turned off, and the high-temperature, high-pressure gaseous refrigerant output from the compressor 31 flows into the in-vehicle condenser 39 through the second solenoid valve 323 to release heat to the passenger compartment. At this time, the state of the refrigerant changes from gas to liquid, and flows into the heat pump heat absorption flow channel c1 of the battery pack 2. At this time, the power distribution assembly a releases a large amount of heat during operation, which is absorbed by the coolant through the power distribution assembly liquid cooling flow channel b1, and then the heat is transferred to the refrigerant in the heat pump heat absorption flow channel c1 through the substrate 11. At this time, the state of the refrigerant changes from liquid to gas again, and flows out of the battery pack 2 and flows into the compressor 31 after passing through the gas-liquid separator 34.

[0072] 3) In the cooling condition, the heat pump heat absorption channel c1 is disconnected, that is, no refrigerant is introduced. The coolant in the power distribution assembly liquid cooling channel b1 flows into the motor radiator 38 through the three-way water valve 351, and the heat absorbed by it is dissipated by the circulating air in the motor radiator 38.

[0073] It should be noted that, for the description of the same contents in this embodiment as those in other embodiments, reference can be made to the description in other embodiments and will not be repeated here.

[0074] The vehicle provided in the embodiment of the present application, because the heat exchange component in the battery pack of the vehicle arranges heat exchange mechanisms on different sides of the substrate, and uses the heat exchange mechanisms to perform efficient heat exchange with the corresponding heat exchange objects, not only can the number of interfaces be reduced, modularization and miniaturization are facilitated, and space utilization is greatly improved, but also the manufacturing cost can be reduced, and the diverse usage requirements can be met, with a wide range of applications.

[0075] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
