[0109] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0110] In the present disclosure, unless otherwise specified and limited, the orientation words "up, down" are defined based on the drawing plane direction, and "up, down" refer to the same direction as the up and down of the vehicle, and "inner, outer" refer to the inner and outer of the related components. In addition, the terms "first, second" and the like used herein are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0111] In addition, in the description of the present disclosure, it should be further explained that, unless otherwise explicitly specified and limited, the terms "provided", "connected", "installed" appearing should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium; it can be the communication between the two elements, and those skilled in the art can understand the specific meaning of the above terms in the present disclosure according to the specific circumstances.

[0112] As Figures 1 to 14As shown, according to an aspect of the present disclosure, a valve group integrated module for a thermal management system is provided, the thermal management system having multiple preset thermal management modes, the valve group integrated module 100 comprising multiple flow channels and a valve group, the multiple flow channels being arranged inside the valve group integrated module 100, the valve group comprising multiple valves, the valves being arranged on the valve group integrated module 100 and being in communication with the flow channels; by switching on or off the valves, the multiple flow channels are communicated to form different fluid passages, thereby realizing at least one of the multiple preset thermal management modes.

[0113] In the above technical solution, the multiple flow channels are arranged inside the valve group integrated module 100 to replace the existing connecting pipelines, which is conducive to reducing the design of the connecting pipelines in the thermal management system; the valve group with multiple valves is integrated on the valve group integrated module 100, which facilitates maintenance and disassembly and also effectively reduces the design of the brackets for installing the valves; in addition, the design of the multiple flow channels inside the valve group integrated module 100 and the design of the multiple valves integrated thereon also facilitate reducing the weight of the valve group integrated module 100, thereby facilitating the lightweight design of the vehicle, reducing the cost and fuel consumption. At the same time, since the use of parts is reduced, the layout space of the vehicle is also reduced. In addition, the multiple flow channels can be flexibly designed on the valve group integrated module 100, so that the arrangement positions of the valves can also be flexibly selected to adapt to different vehicle layouts, thereby facilitating the platform design of the vehicle.

[0114] In an embodiment, the flow channels include first flow channels 110 and second flow channels 120, the first flow channels 110 being arranged in substantially the same plane, and the second flow channels 120 being arranged in different planes, the valve group being configured to selectively communicate the first flow channels 110 and the second flow channels 120 to form different fluid passages.

[0115] By arranging the first flow channels 110 in substantially the same plane, the manufacturing and maintenance of the valve group integrated module 100 are facilitated; by arranging the second flow channels 120 in different planes, when the first flow channels 110 and the second flow channels 120 are selectively communicated by the valve group, multiple different fluid passages can be formed, thereby improving the adaptability of the valve group integrated module 100 to different vehicle models. For example, there are multiple first flow channels 110 and multiple second flow channels 120, and the multiple first flow channels 110 and the multiple second flow channels 120 are selectively switched on by the valve group, thereby further meeting the use requirements of different vehicle models.

[0116] Reference Figure 3 , Figure 5 , Figure 6 , Figure 8 and Figure 11As shown, the valve group integrated module 100 can include a first half 1 and a second half 2, the first half 1 includes a first connecting surface 1001, and the second half 2 includes a second connecting surface 2001, and the first connecting surface 1001 is in sealing connection with the second connecting surface 2001.

[0117] The first half 1 is internally provided with a plurality of second flow channels 120, and the second connecting surface 2001 of the second half 2 is provided with at least one groove, so that the groove on the second connecting surface 2001 cooperates with the first connecting surface 1001 to define a first flow channel 110. When the first half 1 and the second half 2 are attached together, the first connecting surface 1001 of the first half 1 covers the groove on the second connecting surface 2001 of the second half 2, and the part of the first connecting surface 1001 covering the opening of the groove cooperates with the groove wall to form the first flow channel 110.

[0118] By defining the first flow channel 110 between the first half 1 and the second half 2, providing a plurality of second flow channels 120 inside the first half 1, and selectively connecting the first flow channel 110 and the second flow channel 120 through a valve, the fluid can flow in the fluid passage formed by the first flow channel 110 and the second flow channel 120 corresponding to the valve.

[0119] That is, the same first flow channel 110 can be in communication with a plurality of second flow channels 120 to form a fluid passage, and the plurality of second flow channels 120 share the same first flow channel 110, so that the number of flow channels opened in the valve group integrated module 100 can be reduced; on the one hand, the internal structure of the valve group integrated module 100 is simplified, facilitating the processing of the valve group integrated module 100; on the other hand, it can also avoid the problems of disordered arrangement, low integration of the valve group integrated module 100, and large space occupied by the valve group integrated module 100 due to excessive number of flow channels.

[0120] In addition, by forming one or more grooves on the second connecting surface 2001 of the second half 2, the following advantages are obtained:

[0121] First, since the grooves are formed on the second connecting surface 2001 of the second half 2, the second half 2 has a simple structure, and it is more convenient to arrange the positions between the plurality of grooves and flexibly layout the plurality of grooves when designing the plurality of grooves; therefore, the second half 2 can be utilized to a greater extent, and the integration of the valve group integrated module 100 can be improved; in addition, arranging the plurality of grooves on the same surface also facilitates later maintenance;

[0122] Secondly, the groove is set on the second half 2. The second half 2 is set independently from the first half 1. Therefore, the design of the groove will not affect the design and layout of the second flow channel 120 on the first half 1. Setting the groove on the second half 2 does not require avoiding the second flow channel 120 on the first half 1, and makes better use of the reasonable layout of the second flow channel 120 in the first half 1.

[0123] In other embodiments, the interior of the first half 1 is provided with multiple second flow channels 120, and the first connecting surface 1001 on the first half 1 is provided with at least one groove, so that the second connecting surface 2001 and the groove on the first half 1 together define the first flow channel 110. When the first half 1 and the second half 2 are attached together, the second connecting surface 2001 of the second half 2 covers the groove on the first connecting surface 1001 of the first half 1, and the portion of the second connecting surface 2001 covering the opening of the groove together with the groove wall forms the first flow channel 110.

[0124] In this design, both the second flow channel 120 and the groove are located on the first half 1, and the first flow channel 110 is defined by the first half 1 and the second half 2. This allows the main structural design to be concentrated on the first half 1, enabling primary repairs to be performed on it in case of damage. The second half 2 offers greater design flexibility, allowing designers to customize its shape and size according to the different layout spaces of various vehicle models.

[0125] In another modified embodiment, the first half 1 is provided with multiple second flow channels 120 inside, the second connecting surface 2001 of the second half 2 is provided with at least one groove, and the first connecting surface 1001 of the first half 1 is provided with at least one groove; in this way, when the first half 1 and the second half 2 are engaged, the first flow channel 110 can also be defined. This disclosure does not limit the specific design method.

[0126] In order to adapt to different installation scenarios and make more reasonable use of the space of the second half 2, in one embodiment provided in this disclosure, the groove is a curved groove or a straight groove.

[0127] like Figure 6 and Figure 7 As shown, when the groove is a curved groove, in order to reduce the resistance to fluid flow within the first flow channel 110, the included angle θ at the bending position of the curved groove can be 50° to 180°. This results in less flow resistance between the fluid and the groove during fluid flow, making the fluid flow more smoothly and reducing energy consumption during the flow process. Preferably, the included angle θ can be 90° to 180°.

[0128] Here, it needs to be explained that when the included angle of the curved position of the curved groove is 180°, it is configured as a linear groove.

[0129] Optionally, the cross section of the groove is a U-shaped with smooth transition, on the one hand, the U-shaped groove is more convenient to process; on the other hand, the groove with smooth transition can also make the fluid flow in the groove during the process of receiving smaller flow resistance, so that the fluid flows in the first flow channel 110 more smoothly.

[0130] The first half 1 and the second half 2 described above can be configured in any appropriate shape and structure, and can achieve the corresponding functions, which are not limited by the present disclosure.

[0131] In order to further improve the sealing between the first half 1 and the second half 2, a sealing film can also be provided between the first half 1 and the second half 2.

[0132] Optionally, the first half 1 and the second half 2 can be connected by welding process to ensure the stability of the connection between the first half 1 and the second half 2. However, the present disclosure does not limit the connection mode between the first half 1 and the second half 2, and the first half 1 and the second half 2 can also be connected by clamping or bonding, which can ensure the stability of the connection.

[0133] Optionally, referring to Figure 6 As shown in the figure, a plurality of hollow parts 50 are formed on the first half 1, thereby effectively reducing the weight of the first half 1, facilitating the lightweight design of the first half 1, that is, facilitating the lightweight design of the valve group integrated module 100, and further facilitating the lightweight design of the whole vehicle.

[0134] Optionally, the valve group integrated module 100 further comprises an interface, and the interface is used to connect the fluid channel and the external heat exchange component in the thermal management system. By providing the interface on the valve group integrated module 100, the fluid channel in the valve group integrated module 100 and the external heat exchange component in the thermal management system can be directly communicated through the interface, without the need for intermediate adapter and the like to connect, thereby reducing the risk of leakage of the valve group integrated module 100.

[0135] For example, the interfaces described above can include multiple interfaces of a condenser interface, an air-conditioning heat exchanger interface, an evaporator interface, a battery pack heat exchanger interface, a motor heat exchanger interface, an engine heat exchanger interface, a compressor interface, a gas-liquid separator interface, and a PT sensor interface, the condenser interface, the air-conditioning heat exchanger interface, the evaporator interface, the battery pack heat exchanger interface, the motor heat exchanger interface, and the compressor interface being used to connect corresponding external thermal management system components. It should be noted that the corresponding external thermal management system components respectively refer to the condenser 200, the air-conditioning heat exchanger 300, the evaporator 400, the battery pack heat exchanger 500, the motor heat exchanger 700, and the compressor 600.

[0136] Specifically, the condenser interface is used to connect the condenser 200, the air-conditioning heat exchanger interface is used to connect the air-conditioning heat exchanger 300, the evaporator interface is used to connect the evaporator 400, the battery pack heat exchanger interface is used to connect the battery pack heat exchanger 500, the motor heat exchanger interface is used to connect the motor heat exchanger 700, and the compressor interface is used to connect the compressor 600.

[0137] By providing interfaces for communicating with external thermal management system components on the valve group integration module 100, the communication between the fluid passages in the valve group integration module 100 and the external thermal management system components can be facilitated to achieve different preset thermal management modes. In addition, the use of fluid passages inside the valve group integration module 100 to replace existing connecting pipelines can also reduce the design of the pipelines and facilitate lightweight design.

[0138] In an embodiment, the interfaces described above can include a condenser interface, an air-conditioning heat exchanger interface, an evaporator interface, and a compressor interface. The condenser interface is used to connect the condenser 200 in the external thermal management system, the air-conditioning heat exchanger interface is used to connect the air-conditioning heat exchanger 300 in the external thermal management system, the evaporator interface is used to connect the evaporator 400 in the external thermal management system, and the compressor interface is used to connect the compressor 600 in the external thermal management system. Of course, the present disclosure does not limit the types of interfaces on the valve group integration module 100, and designers can set them according to their needs.

[0139] Optionally, with reference to Figure 1 and Figure 2As shown, the condenser interface can include a condenser outlet interface 202, the air conditioner heat exchanger interface includes an air conditioner heat exchanger inlet interface 203 and an air conditioner heat exchanger outlet interface 204, and the evaporator interface includes an evaporator inlet interface 205. The valve group includes a first on-off valve 21 and a second expansion valve 32; a first port of the first on-off valve 21 is connected to the condenser outlet interface 202, and a second port of the first on-off valve 21 is connected to the air conditioner heat exchanger inlet interface 203; a first port of the second expansion valve 32 is connected to the air conditioner heat exchanger outlet interface 204, and a second port of the second expansion valve 32 is connected to the evaporator inlet interface 205, so that the thermal management system can realize the air conditioner refrigeration mode in the preset thermal management mode.

[0140] In the above technical solution, compared with the existing air conditioner refrigeration mode, because the condenser outlet interface 202 and the air conditioner heat exchanger inlet interface 203 are arranged on the valve group integrated module 100, and the fluid channel connecting the condenser outlet interface 202 and the air conditioner heat exchanger inlet interface 203 is arranged inside the valve group integrated module 100, the fluid channel can be used to replace the connecting pipeline for connecting the condenser 200 and the air conditioner heat exchanger 300 in the prior art; the air conditioner heat exchanger outlet interface 204 and the evaporator inlet interface 205 are integrated on the valve group integrated module 100, and the fluid channel connecting the air conditioner heat exchanger outlet interface 204 and the evaporator outlet interface 206 must exist inside the valve group integrated module 100, so the fluid channel can be used to replace the connecting pipeline for connecting the air conditioner heat exchanger 300 and the evaporator 400 in the prior art; and the first on-off valve 21 and the second expansion valve 32 are connected to the fluid channel, and the flow path is controlled, which will be described in detail below when the specific structure of the first flow channel 110 is introduced.

[0141] Optionally, in the air conditioner refrigeration mode, the specific working process can be as follows:

[0142] As Figure 1 and Figure 2As shown, the compressor 600 discharges high-temperature and high-pressure gaseous refrigerant, which flows to the inlet of the condenser 200 through the pipeline, and the refrigerant communicates with the condenser outlet interface 202 on the valve group integrated module 100 through the outlet of the condenser 200 (the condenser 200 can not perform heat release work at this time), so as to enter the fluid passage. The valve group integrated module 100 is provided with a first on-off valve 21 in communication with the fluid passage, and the first on-off valve 21 is in an open state. The refrigerant flows to the air conditioner heat exchanger inlet interface 203 through the first on-off valve 21, which is in communication with the inlet of the air conditioner heat exchanger 300. The refrigerant enters the air conditioner heat exchanger 300 to exchange heat. The cooled refrigerant flows out of the outlet of the air conditioner heat exchanger 300 and flows to the air conditioner heat exchanger outlet interface 204 to re-enter the fluid passage of the valve group integrated module 100. The valve group integrated module 100 is provided with a second expansion valve 32 in communication with the fluid passage. The refrigerant flows to the evaporator inlet interface 205 through the second expansion valve 32 after throttling and pressure reduction. The evaporator inlet interface 205 can be in communication with the inlet of the evaporator 400 through the pipeline. The throttled and pressure-reduced refrigerant enters the evaporator 400 through the pipeline to evaporate to absorb heat from the environment. The cooled ambient temperature is blown into the member cabin by the air blower to achieve refrigeration. The refrigerant after the evaporator 400 flows to the compressor 600 through the pipeline. The gaseous refrigerant enters the compressor 600 to perform refrigeration cycle work.

[0143] Referring to Figure 1 and Figure 2 As shown, the valve group can further include a first expansion valve 31 and a second on-off valve 22. The first port of the first expansion valve 31 is connected with the condenser outlet interface 202, and the second port of the first expansion valve 31 is connected with the air conditioner heat exchanger inlet interface 203. The first port of the second on-off valve 22 is connected with the air conditioner heat exchanger outlet interface 204, and the second port of the second on-off valve 22 is connected with the inlet of the compressor 600, so that the heat management system can realize the air conditioner heating mode in the preset heat management mode.

Similarly, in the air conditioner heating mode, the fluid passage in the valve group integrated module 100 can also replace the connection pipeline for connecting the condenser 200 and the air conditioner heat exchanger 300 in the prior art, and replace the connection pipeline for connecting the air conditioner heat exchanger 300 and the evaporator 400 in the prior art, so as to reduce the design of the connection pipeline in the air conditioner heating mode and facilitate lightweight design.

The valve group integrated module 100 is provided with the first expansion valve 31 and the second on-off valve 22 in communication with the fluid passage. The refrigerant flows to the air conditioner heat exchanger inlet interface 203 after throttling and pressure reduction by the first expansion valve 31. The air conditioner heat exchanger inlet interface 203 can be in communication with the air conditioner heat exchanger 300 through a pipeline. The refrigerant enters the air conditioner heat exchanger 300 for heat exchange. The heat-exchanged refrigerant enters the fluid passage of the valve group integrated module 100 through the air conditioner heat exchanger outlet interface 204. Then, the refrigerant flows to the inlet of the compressor 600 through the second on-off valve 22. The gaseous refrigerant enters the compressor 600 for heating cycle operation.

The refrigerant passing through the condenser 200 enters the first expansion valve 31 through a pipeline, and the first expansion valve 31 throttles and depressurizes the refrigerant, and then the refrigerant enters the motor heat exchanger 700. The refrigerant absorbs heat and evaporates in the motor heat exchanger 700, and then the evaporated refrigerant enters the third expansion valve 33 through a pipeline. The refrigerant throttles and depressurizes in the third expansion valve 33, and then enters the battery pack heat exchanger 500 to absorb heat and cool the battery pack. The refrigerant passing through the battery pack heat exchanger 500 enters the fourth on-off valve 24, and then enters the compressor through the open fourth on-off valve 24, so as to realize the circulation work of the double-open mode of the heat pump heating and the battery cooling.

[0166] Optionally, in the heat pump heating and battery heating double-open mode, the specific working process can be as follows:

[0167] Referring to Figure 1 and Figure 2 , the refrigerant flows out of the compressor and is divided into two paths:

[0168] One path enters the condenser 200 through a pipeline, and the refrigerant releases heat in the condenser 200. The condenser 200 releases heat in combination with the air heating PTC to heat the vehicle. The refrigerant passing through the condenser 200 enters the first expansion valve 31, and the first expansion valve 31 throttles and depressurizes the refrigerant. The refrigerant flowing out of the first expansion valve 31 enters the motor heat exchanger 700, and then absorbs heat and evaporates in the motor heat exchanger 700.

[0171] Optionally, in the air conditioning dehumidification mode, the specific working process can be as follows:

[0172] Referring to Figure 1 and Figure 2As shown, the compressor 600 discharges high-temperature and high-pressure gaseous refrigerant into the condenser 200, and the refrigerant is discharged into the first switch valve 21 after heat release in the condenser 200. At this time, the first switch valve 21 is fully opened, and the refrigerant enters the air conditioner heat exchanger 300 or the motor heat exchanger 700 after passing through the first switch valve 21. The refrigerant enters the second expansion valve 32 after heat exchange in the air conditioner heat exchanger 300 or the motor heat exchanger 700, is throttled and decompressed, and enters the evaporator 400 to absorb the heat of the indoor environment to make the indoor humid air reach the dew point temperature and condense into water to achieve the effect of dehumidification. The dehumidified environment is heated by the condenser 200 to make the indoor environment reach a more comfortable temperature, and the air is blown into the passenger compartment by the fan to achieve a more comfortable temperature in the passenger compartment. The refrigerant passing through the evaporator 400 enters the compressor to complete the dehumidification cycle.

[0173] Alternatively, in the air conditioning refrigeration, air conditioning dehumidification and battery cooling three-open mode, the specific working process can be as follows:

[0174] Referring to Figure 1 and Figure 2 , the compressor 600 discharges high-temperature and high-pressure gaseous refrigerant, which enters the condenser 200 through pipeline connection, and the refrigerant enters the first switch valve 21 after passing through the condenser 200 (the condenser 200 can not work at this time). At this time, the first switch valve 21 is fully opened, and the refrigerant enters the air conditioner heat exchanger 300 after passing through the first switch valve 21. The refrigerant is divided into two paths after heat exchange:

[0175] One path enters the second expansion valve 32 through the pipeline to be throttled and decompressed, and the refrigerant enters the evaporator 400 through the pipeline connection to absorb the heat of the indoor environment to make the indoor humid air reach the dew point temperature and condense into water to achieve the effect of dehumidification. The dehumidified environment is heated by the condenser 200 to make the indoor environment reach a more comfortable temperature, and the air is blown into the passenger compartment by the fan to achieve a more comfortable temperature in the passenger compartment. The refrigerant passing through the evaporator 400 enters the compressor 600.

[0176] The other path enters the third expansion valve 33 from the air conditioner heat exchanger 300, and the refrigerant enters the battery pack heat exchanger 500 to absorb heat and cool the battery pack after being throttled and decompressed in the third expansion valve 33. The refrigerant passing through the battery pack heat exchanger 500 enters the compressor 600 through the fourth switch valve 24.

[0177] Alternatively, in the air conditioning refrigeration, air conditioning dehumidification and battery heating three-open mode, the specific working process can be as follows:

[0178] Referring to Figure 1 and Figure 1 , the compressor 600 discharges high-temperature and high-pressure gaseous refrigerant, which is divided into two paths:

[0179] The first refrigerant enters the condenser 200 via a pipeline. After releasing heat in the condenser 200, the refrigerant is connected to the first switching valve 21 via a pipeline. At this time, the first switching valve 21 is fully open, and the refrigerant enters the air conditioning heat exchanger 300 through the pipeline via the first switching valve 21. After heat exchange in the air conditioning heat exchanger 300, the refrigerant enters the second expansion valve 32. After being throttled and depressurized in the second expansion valve 32, the refrigerant enters the evaporator 400 to absorb heat from the vehicle's interior environment, causing the warm and humid air inside the vehicle to reach the dew point temperature and condense into water, which is then discharged, achieving a dehumidification effect. The dehumidified environment, combined with the heat released by the condenser 200, brings the ambient temperature to a more comfortable level. The fan blows the air into the passenger compartment, bringing the passenger compartment to a more comfortable ambient temperature. The refrigerant after passing through the evaporator 400 is then connected to the compressor 600 via a pipeline.

[0180] The second route connects to the third switching valve 23 via a pipeline. The refrigerant passing through the third switching valve 23 enters the battery pack heat exchanger 500 to heat the battery pack. The refrigerant passing through the battery pack heat exchanger 500 then enters the third expansion valve 33 via a pipeline for throttling and pressure reduction. The throttled and pressure-reduced refrigerant then enters the motor heat exchanger 700 for heat absorption and evaporation. The evaporated refrigerant then enters the second expansion valve 32 via a pipeline, merging with the first route of refrigerant mentioned above.

The first port of the sixth switching valve 26 is connected to the second port of the first switching valve 21 and the second port of the first expansion valve 31, respectively. The second port of the sixth switching valve 26 is used to connect to the inlet interface 203 of the air conditioning heat exchanger. By integrating the fifth switching valve 25 into the valve assembly integration module 100, the refrigerant flowing out from the first switching valve 21 and the first expansion valve 31 can be opened or closed to selectively enter the air conditioning heat exchanger 300, improving the flexibility of flow path control. Similarly, by integrating the sixth switching valve 26 into the valve assembly integration module 100, the refrigerant flowing out from the first switching valve 21 and the first expansion valve 31 can also be opened or closed to selectively enter the motor heat exchanger 700, improving the flexibility of flow path control.
