Furthermore, the refrigerant piping requires robust piping, and existing thermal management systems use a large amount of refrigerant piping, reducing their economic efficiency and increasing their weight.

[0053] Exemplary embodiments of this application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of this application and to fully convey the scope of this application to those skilled in the art.

[0054] The vehicle's thermal management system manages the passenger compartment and power system through independent modules. When managing the passenger compartment and power system, the thermal management system activates the corresponding modules and exchanges heat between the passenger compartment and power system through the refrigerant in the modules.

[0055] However, existing thermal management systems have low integration and lack heat exchange between the passenger compartment and the power system, resulting in low thermal utilization. Furthermore, the refrigerant piping requires robust piping, and existing thermal management systems use a large amount of refrigerant piping, reducing their economic efficiency and increasing their weight.

[0056] To address the problems of existing thermal management systems requiring extensive refrigerant piping, exhibiting low integration, and low thermal efficiency, embodiments of this application propose an integrated thermal management system 100 that improves integration, increases thermal efficiency, and reduces the amount of refrigerant piping used.

[0057] Embodiments of this application also propose a vehicle including the integrated thermal management system 100 as described above.

[0058] The integrated thermal management system 100 and the vehicle according to embodiments of this application are described below with reference to the accompanying drawings.

[0059] It should be noted that, Figures 2 to 25 In the diagram, thick lines represent pipes connected in the integrated thermal management system 100, and thin lines represent pipes not connected in the integrated thermal management system 100.

[0060] Combination Figures 1 to 25As shown, the integrated thermal management system 100 of this application embodiment includes a compression cycle subsystem 10, an air conditioning subsystem 20, and a power subsystem 30. The compression cycle subsystem 10 is provided with a first medium and forms a first circulation pipeline 11; the air conditioning subsystem 20 is provided with a second medium, and the air conditioning subsystem 20 is heat-exchange connected to the compression cycle subsystem 10 and configured to exchange heat with the second medium in the air conditioning subsystem 20 through the first medium; the power subsystem 30 is used to provide power for the movement of the vehicle, and the power subsystem 30 is provided with a second medium. The power subsystem 30 is connected to the air conditioning subsystem 20 in a switchable manner, so that the power subsystem 30 and the air conditioning subsystem 20 can exchange heat through the second medium, wherein the first medium is a refrigerant, and the second medium is water or a water-based medium.

[0061] It should be noted that water-based media refers to media in which water is the main component.

[0062] The integrated thermal management system 100 of this application embodiment can integrate the compression cycle subsystem 10, the air conditioning subsystem 20 and the power subsystem 30, thereby having a high degree of integration.

[0063] When the compression cycle subsystem 10 starts, the first medium circulates within the first circulation pipeline 11. Since the air conditioning subsystem 20 exchanges heat with the compression cycle subsystem 10 through the second medium, during the circulation of the first medium, the first medium exchanges heat with the second medium within the air conditioning subsystem 20, enabling the air conditioning subsystem 20 to cool or heat the passenger compartment. Thus, the air conditioning subsystem 20, operating independently of the compression cycle subsystem 10, can exchange heat with the compression cycle subsystem 10 to manage the thermal performance of the passenger compartment.

[0064] By setting the compression cycle subsystem 10 and the air conditioning subsystem 20 independently, different media can be used between the air conditioning subsystem 20 and the compression cycle subsystem 10. The compression cycle subsystem 10 uses a first medium, while the air conditioning subsystem 20 and the power subsystem 30 use a second medium. This reduces the amount of refrigerant used, thereby improving the economy of the integrated thermal management system of this embodiment and reducing its weight.

[0065] By using a second medium in both the air conditioning subsystem 20 and the power subsystem 30, and by making the power subsystem 30 and the air conditioning subsystem 20 connectable and disconnectable, the air conditioning subsystem 20 and the power subsystem 30 can form thermal contact through the same medium when they are connected, thereby facilitating heat exchange between the air conditioning subsystem 20 and the power subsystem 30.

[0066] When the power subsystem 30 and the air conditioning subsystem 20 are connected, heat exchange occurs between them through a second medium. The heat exchange can occur either with the power subsystem 30 absorbing heat from the air conditioning subsystem 20, or vice versa, thus enabling heat exchange between them. This allows the heat between the power subsystem 30 and the air conditioning subsystem 20 to be mutually utilized, thereby improving the thermal efficiency of the integrated thermal management system 100 according to this embodiment.

[0067] When the power subsystem 30 and the air conditioning subsystem 20 are disconnected, heat exchange between the power subsystem 30 and the air conditioning subsystem 20 stops, thus avoiding mutual interference between the power subsystem 30 and the air conditioning subsystem 20.

[0068] The power subsystem 30 and the air conditioning subsystem 20 can be connected to each other, which can also increase the number of usage modes of the integrated thermal management system 100 in this embodiment. By increasing the number of usage modes, the mode of the integrated thermal management system 100 in this embodiment can be flexibly adjusted according to different environments and user needs, thereby increasing the adaptability of the integrated thermal management system 100 to the environment and improving the user experience.

[0069] The integrated thermal management system 100 of this application embodiment integrates a compression cycle subsystem 10, an air conditioning subsystem 20, and a power subsystem 30, thereby achieving a high degree of integration. Since the compression cycle subsystem 10 and the air conditioning subsystem 20 are independently configured, different media can be used between them, thus reducing the amount of refrigerant used. By allowing the power subsystem 30 and the air conditioning subsystem 20 to be connected on and off, heat exchange can occur between the air conditioning subsystem 20 and the compression cycle subsystem 10, thereby improving thermal efficiency.

[0070] Combination Figures 1 to 25 As shown, in some embodiments, the power subsystem 30 includes an electric drive module 31 and a battery module 32. Both the electric drive module 31 and the battery module 32 are provided with a second medium. The air conditioning subsystem 20, the electric drive module 31 and the battery module 32 are interconnected and can exchange heat through the second medium.

[0071] When the electric drive module 31 and the air conditioning subsystem 20 are connected, heat exchange occurs between them through a second medium. This allows the heat between the electric drive module 31 and the air conditioning subsystem 20 to be utilized, thereby improving the thermal efficiency of the integrated thermal management system 100 according to this embodiment.

[0072] When the connection between the electric drive module 31 and the air conditioning subsystem 20 is disconnected, the heat exchange between the electric drive module 31 and the air conditioning subsystem 20 stops, thus avoiding mutual interference between the electric drive module 31 and the air conditioning subsystem 20.

[0073] When the battery module 32 and the air conditioning subsystem 20 are connected, heat exchange occurs between them through a second medium. This allows the heat between the battery module 32 and the air conditioning subsystem 20 to be utilized, thereby improving the thermal efficiency of the integrated thermal management system 100 according to this embodiment.

[0074] When the connection between the battery module 32 and the air conditioning subsystem 20 is disconnected, the heat exchange between the battery module 32 and the air conditioning subsystem 20 stops, thus avoiding mutual interference between the battery module 32 and the air conditioning subsystem 20.

[0075] When the electric drive module 31 and the battery module 32 are connected, heat exchange occurs between them through a second medium. This allows the heat between the electric drive module 31 and the battery module 32 to be utilized, thereby improving the thermal efficiency of the integrated thermal management system 100 according to this embodiment.

[0076] When the connection between the electric drive module 31 and the battery module 32 is disconnected, heat exchange between the electric drive module 31 and the battery module 32 stops, thus avoiding mutual interference between the electric drive module 31 and the battery module 32.

[0077] In this embodiment of the integrated thermal management system 100, the heat between the electric drive module 31, the battery module 32, and the air conditioning subsystem 20 can be utilized, thereby improving the thermal utilization rate of the integrated thermal management system 100 of this application embodiment. Therefore, the air conditioning subsystem 20, the electric drive module 31, and the battery module 32 can be interconnected, further increasing the usage modes of the integrated thermal management system 100 of this embodiment.

[0078] Combination Figure 1 , Figure 3 , Figure 13 and Figure 25 As shown, in some embodiments, the battery module 32 includes a battery module 321 and a battery heat exchanger 322. Both the battery module 321 and the battery heat exchanger 322 are provided with a second medium and are interconnected. The first circulation pipeline 11 is connected to the battery heat exchanger 322 and configured to exchange heat with the second medium in the battery heat exchanger 322 through the first medium. That is, a heat exchange connection can be formed between the compression circulation subsystem 10 and the battery heat exchanger 322, thereby enabling heat dissipation from the battery heat exchanger 322.

[0079] When the compression circulation subsystem 10 is started, the first medium circulates within the first circulation pipeline 11. During the circulation of the first medium, the first medium exchanges heat with the second medium in the battery heat exchanger 322, enabling the battery heat exchanger 322 to exchange heat with the battery module 321.

[0080] Since both the air conditioning subsystem 20 and the battery heat exchanger 322 can form a heat exchange connection with the compression cycle subsystem 10, the air conditioning subsystem 20 and the battery heat exchanger 322 can form an indirect heat connection through the compression cycle subsystem 10. The air conditioning subsystem 20 and the battery heat exchanger 322 can also form a direct heat connection through the second medium. This increases the heat exchange efficiency between the air conditioning subsystem 20 and the battery heat exchanger 322 and further enhances the integrated thermal management system 100 of this embodiment.

[0081] By setting the compression cycle subsystem 10, the air conditioning subsystem 20, and the battery module 32 independently, the compression cycle subsystem 10 can act on the air conditioning subsystem 20 and the battery module 32 respectively, thereby increasing the heat exchange path and improving the heat utilization efficiency.

[0082] When the battery heat exchanger 322 cools the battery module 321, it can also provide evaporation for the first medium in the first circulation pipeline 11. During the process of evacuating or adding the first medium to the compression circulation subsystem 10, the coordinated operation of the battery heat exchanger 322, the battery module 321, and the compression circulation subsystem 10 enables the compression circulation subsystem 10 to establish normal operating pressure, thereby allowing the compression circulation subsystem 10 to be evacuated or added with the first medium.

[0083] Therefore, the compression cycle subsystem 10 of this application embodiment can work in conjunction with the battery module 32 to establish normal operating pressure, and can also work in conjunction with the air conditioning subsystem 20 to establish normal pressure, thereby further increasing the modes of the integrated thermal management system 100 of this application embodiment.

[0084] Combination Figures 2 to 25 In some embodiments, the battery module 32 further includes a first pipe 323 and a second pipe 324. The first pipe 323 has a first port 323a and a second port 323b, and the second pipe 324 has a third port 324a and a fourth port 324b. The first port 323a and the second port 323b are both connected to the first valve body c. The third port 324a is connected to the second port 323b, and the fourth port 324b is connected to the second valve body d. The battery module 321 is connected to the first pipe 323, the battery heat exchanger 322 is connected to the second pipe 324, and the first valve body c and the second valve body d are interconnected.

[0085] The connection between the port and the valve body can be either a direct connection between the port and the valve body, or an indirect connection between the port and the valve body via other pipelines.

[0086] like Figure 13 As shown, when the first valve body c opens to connect with the first port 323a and disconnects from the second port 323b, the second valve body d opens to connect with the fourth port 324b, and the first valve body c and the second valve body d are connected. A closed loop is formed between the battery module 321, the battery heat exchanger 322, the first valve body c, and the second valve body d. The second medium circulates between the battery module 321, the battery heat exchanger 322, the first valve body c, and the second valve body d, thereby cooling the battery module 321 through the battery heat exchanger 322.

[0087] like Figure 25 As shown, when the first valve body c opens to connect with the first port 323a and disconnects from the second port 323b, the second valve body d opens to connect with the fourth port 324b, and the first valve body c disconnects from the second valve body d, a series pipeline is formed between the battery module 321 and the battery heat exchanger 322, thereby facilitating the connection between the battery module 321 and the battery heat exchanger 322 and other parts.

[0088] like Figure 6 As shown, when the integrated thermal management system 100 of this embodiment is in the fifth mode, the first valve body c opens the connection with the first port 323a and opens the connection with the second port 323b, and the second valve body d port disconnects the connection with the fourth port 324b. In the fifth mode, the second medium can circulate in the battery module 321, thereby cooling the battery module 321.

[0089] The integrated thermal management system 100 of this embodiment is connected to the first valve body c through the first port 323a and the second port 323b, the third port 324a is connected to the second port 323b, and the fourth port 324b is connected to the second valve body d. The first valve body c and the second valve body d are interconnected. By controlling the connection relationship between each port and the valve body, the connection relationship between the battery module 321 and the battery heat exchanger 322 can be flexibly changed. Moreover, the battery module 321 and the battery heat exchanger 322 can be selectively connected, thereby further increasing the number of modes of the integrated thermal management system 100 of this embodiment.

[0090] In some preferred embodiments, the first valve body c and the second valve body d are both multi-port valves, which can independently control the on / off state of each port, thereby improving control performance.

[0091] Combination Figures 2 to 25In some specific embodiments, the battery module 321 includes a battery 3211 and a third pump body 3212, both of which are located in the first pipeline 323. The third pump body 3212 can provide a power source and drive the flow of the second medium.

[0092] Combination Figures 2 to 25 In some embodiments, the battery module 32 further includes a heating module 325 and a third pipe 326. The third pipe 326 has a fifth port 326a and a sixth port 326b. The fifth port 326a, the third port 324a and the second port 323b are interconnected. The sixth port 326b is interconnected with the second valve body d. The heating module 325 is connected to the third pipe 326.

[0093] like Figure 3 As shown, when the integrated thermal management system of this embodiment is in the second mode, the first valve body c opens to connect with the first port 323a and disconnects from the second port 323b, the second valve body d opens to connect with the fourth port 324b, the first valve body c opens to connect with the second valve body d, the sixth port 326b opens to connect with the second valve body d, and the compression cycle subsystem 10 operates.

[0094] In the second mode, the battery module 321, battery heat exchanger 322, and heating module 325 are all interconnected, enabling the battery module 32 to establish normal operating pressure in the compression cycle subsystem 10, allowing the compression cycle subsystem 10 to be evacuated or injected with the first medium. Furthermore, through the connections between the first pipe 323, the second pipe 324, the third pipe 326, the first valve body c, and the second valve body d, the battery module 321 and battery heat exchanger 322 are connected in parallel, and the battery module 321 and battery heat exchanger 322 are connected in series with the heating module 325. This allows for reasonable flow planning and distribution of the second medium, ensuring the normal operation of the battery module 32.

[0095] As an example, in the second mode, the battery module 321 compression cycle subsystem 10 can be evacuated or filled with a first medium.

[0096] like Figure 4 As shown, when the integrated thermal management system of this embodiment is in the third mode, the first valve body c opens to connect with the first port 323a and disconnects from the second port 323b, the second valve body d disconnects from the fourth port 324b, the first valve body c opens to connect with the second valve body d, and the sixth port 326b opens to connect with the second valve body d.

[0097] In the third mode, the battery module 321 and the heating module 325 are connected, enabling the heating module 325 to heat the battery module 321.

The evaporator 21 is connected to the sixth pipe 25, the cooling / heating core 24 is connected to the seventh pipe 26, and the first pump body 22 is connected to one of the sixth pipe 25 and the seventh pipe 26. The cooling / heating core 24 and the evaporator 21 are both connected to the air outlet of the fan 23.

[0127] The integrated thermal management system 100 of this embodiment is interconnected with the eleventh port 25a, the thirteenth port 26a and the third valve body e, and interconnected with the twelfth port 25b, the fourteenth port 26b and the first valve body c. This allows for flexible changes in the connection relationships between the air conditioning subsystem 20, the electric drive module 311, the heat dissipation module 312, the heating module 325, the battery module 321 and the battery heat exchanger 322.

The heat or cold from the heating / cooling core 24 is blown to the passenger compartment by the fan 23, thus enabling the air conditioning subsystem 20 to perform thermal management of the passenger compartment. The fan 23 can also blow heat or cold from the evaporator 21 to the passenger compartment, thereby improving thermal efficiency.

The air conditioning subsystem 20 can cool or heat the battery module 321, thereby increasing the mode of the integrated thermal management system 100 in this embodiment. The battery module 321 can absorb the residual heat of the air conditioning subsystem 20, thereby further increasing the thermal efficiency.

[0143] As some examples, in the fourteenth mode, the air conditioning subsystem 20 cools, thereby cooling the crew cabin and battery module 321.

[0144] In some other embodiments, in the fourteenth mode, the air conditioning subsystem 20 heats the passenger compartment and the battery module 321 via a second medium.

[0145] In some other embodiments, in the fourteenth mode, the air conditioning subsystem 20 heats the battery module 321 by blowing heat from the heating / cooling core 24 to the battery module 321 via the fan 23.

[0146] like Figure 16As shown, when the integrated thermal management system 100 of this embodiment is in the fifteenth mode, the seventh port 313a is disconnected from the third valve body e, the eighth port 313b is disconnected from the third valve body e, the tenth port 314b is disconnected from the second valve body d, the second valve body d and the third valve body e are connected, the first valve body c and the second valve body d are connected, the first valve body c and the third valve body e are disconnected, the first port 323a is connected to the first valve body c, the second port 323b is disconnected from the first valve body c, the fourth port 324b is disconnected from the second valve body d, the sixth port 326b is connected to the second valve body d, the twelfth port 25b and the fourteenth port 26b are disconnected from the first valve body c, the eleventh port 25a and the thirteenth port 26a are disconnected from the third valve body e, and the compression cycle subsystem 10 is started.

[0147] In the fifteenth mode, the air conditioning subsystem 20, battery module 321, heating module 325, and compression cycle subsystem 10 are all turned on, but the connection between the air conditioning subsystem 20 and the battery module 32 is disconnected, the heat exchange between the air conditioning subsystem 20 and the battery module 32 stops, the battery module 32 and the air conditioning subsystem 20 work independently, the battery module 321 is heated by the heating module 325, and the temperature of the passenger compartment is managed by the coordinated work between the compression cycle subsystem 10 and the air conditioning subsystem 20.

[0148] As some examples, in the fourteenth mode, the air conditioning subsystem 20 cools the passenger compartment, and the heating module 325 heats it.

[0149] As other examples, in the fourteenth mode, the air conditioning subsystem 20 heats the passenger compartment, and the heating module 325 heats the passenger compartment.

[0151] In the sixteenth mode, both the air conditioning subsystem 20 and the heating module 325 are activated. When the air conditioning subsystem 20 starts, the heating module 325 heats the passenger compartment, thus providing sufficient start-up time for the air conditioning subsystem 20. The air conditioning subsystem 20 can more precisely deliver the heat generated by the heating module 325 into the passenger compartment. The combined heating of the air conditioning subsystem 20 and the heating module 325 further enhances the heating effect on the passenger compartment. Therefore, the sixteenth mode enables heating of the passenger compartment even in low-temperature environments.

The air conditioning subsystem 20 and the heating module 325 can work together to heat the passenger compartment, further improving the heating effect. The heating module 325 can also heat the battery module 321, maintaining it at a suitable operating temperature. Furthermore, the overheating module 325 is connected in parallel to the air conditioning subsystem 20 and the battery module 321.

[0163] In the twenty-second mode, the heat dissipation module 312, battery module 321, air conditioning subsystem 20, and electric drive module 311 are connected and can exchange heat with each other. The heating and cooling cores 24 of the battery module 321 and air conditioning subsystem 20 absorb heat from the electric drive module 311, thereby heating the battery module 321 and the passenger compartment, and cooling the electric drive module 311.

The twenty-first port 114a, the eighteenth port 112b and the twentieth port 113b are connected to each other. The twenty-second port 114b, the sixteenth port 111b and the fourth valve body f are connected to each other.

[0172] like Figure 3 As shown, when the compression cycle subsystem 10 needs to work in conjunction with the battery module 32, it opens the connection between the fifteenth port 111a and the fourth valve body f, disconnects the connection between the sixteenth port 111b and the fourth valve body f, opens the connection between the seventeenth port 112a and the fourth valve body f, disconnects the connection between the nineteenth port 113a and the fourth valve body f, opens the connection between the first expansion valve 15 and the third expansion valve 17, and disconnects the connection between the second expansion valve 16. Thus, the first medium can circulate between the eighth pipeline 111, the ninth pipeline 112 and the eleventh pipeline 114.

[0173] Combination Figure 13 and Figure 25 As shown, when the battery module 32 and the air conditioning subsystem 20 are working with the compression cycle subsystem 10, the connection between each of the fifteenth port 111a, the sixteenth port 111b, the seventeenth port 112a and the nineteenth port 113a and the fourth valve body f is opened, and the connection between the first expansion valve 15, the second expansion valve 16 and the third expansion valve 17 is opened.

[0175] The vehicle in this application embodiment includes the integrated thermal management system 100 as described in the above embodiment.

[0176] The vehicle of this embodiment includes the integrated thermal management system 100 as described in the previous embodiment, integrating the compression cycle subsystem 10, the air conditioning subsystem 20, and the power subsystem 30, thereby achieving a high degree of integration. Since the compression cycle subsystem 10 and the air conditioning subsystem 20 are independently configured, different media can be used between them, thus reducing the amount of refrigerant used. By allowing the power subsystem 30 and the air conditioning subsystem 20 to be connected in a switchable manner, heat exchange can occur between them, thereby improving heat utilization efficiency. Therefore, the integration level of the vehicle in this embodiment is improved, the weight of the vehicle in this embodiment is reduced, and the fuel economy of the vehicle in this embodiment is improved.

Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0178] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure rotates, then an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0180] In the description of the application, the technical terms "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "circumferential", "height direction", "first direction", "second direction", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed, operated or used in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0181] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between components; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
