[0069] Embodiments of the present invention will now be described in detail. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

They are used only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0072] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0073] This application provides a flow channel structure, which will be described in detail below with reference to the accompanying drawings.

[0074] Reference Figure 1 The diagram shows a schematic representation of a flow channel structure provided in an embodiment of this application. (Refer to...) Figures 2 to 5 The diagram shows a structural schematic of the ontology provided in an embodiment of this application. (Refer to...) Figures 6 to 8 The figures AA, BB, and CC sectional views of the body provided in the embodiments of this application are shown respectively.

[0075] like Figures 1 to 8 As shown, this application provides a flow channel structure, including: a body 1, a first layer flow channel 2, and a second layer flow channel 3; the first layer flow channel 2 and the second layer flow channel 3 are disposed at intervals along a first direction X on the body 1; the first layer flow channel 2 includes M independent first flow channels; the second layer flow channel 3 includes N independent second flow channels, of which L second flow channels are straight flow channels, and L≤N; wherein, one first flow channel is connected to at least two second flow channels to allow fluid to flow between the first layer flow channel 2 and the second layer flow channel 3.

[0076] In this embodiment, because a first layer of flow channels 2 and a second layer of flow channels 3 are provided, and the first layer of flow channels 2 includes M independent first flow channels and the second layer of flow channels 3 includes N independent second flow channels, more flow channels can be set within the body 1, which is beneficial to improving the flexibility and integration of the flow channel structure. Furthermore, the function of the first layer of flow channels 2 is to connect different second flow channels. Compared to setting one first flow channel to connect all second flow channels, setting multiple first flow channels, and one first flow channel connecting to at least two second flow channels, simplifies the structure of the first layer of flow channels 2 and reduces the processing difficulty of the flow channel structure. More importantly, since L of the second flow channels are straight flow channels, where L≤N, meaning at least some of the second flow channels are straight flow channels, the distance and / or resistance of the fluid flowing within the straight second flow channels can be reduced, thereby reducing the flow resistance of the fluid in the entire flow path and improving the thermal management efficiency of the vehicle.

[0077] It should be noted that a straight flow channel refers to a structure in which fluid can flow in a straight line within the channel. Furthermore, the first direction X refers to the thickness direction of the body 1, i.e., the vertical direction, and the second direction Y refers to the length or width direction of the body 1, i.e., the horizontal direction. The first direction X is perpendicular to the second direction Y. In addition, since the first flow channel in this embodiment is used to connect different second flow channels, thereby realizing different operating modes of the thermal management module, the number of first flow channels is usually less than the number of second flow channels. In one embodiment, such as... Figures 2 to 3 As shown, the first flow channel has six channels, and the second flow channel has three channels. The length and shape of the second flow channel depend on the position and spacing of the control valve, sensor, etc.

[0078] In practical applications, multiple mounting parts 12 are provided around the main body 1. The mounting parts 12 are fixedly installed to the vehicle bracket with screws to achieve reliable fixation of the flow channel structure. A shock-absorbing pad is also provided between the mounting parts 12 and the vehicle bracket to reduce vibration and prevent damage to the flow channel structure.

[0079] In some optional embodiments of this application, the body 1 includes two first sidewalls 18 extending along a second direction Y, the second direction Y being perpendicular to the first direction X; the body 1 is also provided with a plurality of connection ports 4, the plurality of connection ports 4 being disposed on the first sidewalls 18, and one connection port 4 communicating with a first flow channel or a second flow channel.

[0080] Depend on Figure 3 and Figure 5 It can be seen that both the first and second flow channels extend in the horizontal direction. When the connection port 4 is set on the first side wall 18, the fluid can enter the first or second flow channel in the horizontal direction through the connection port 4, so that the flow direction does not change much or even does not change, thereby reducing the flow resistance of the fluid.

[0081] It should be noted that the multiple connection ports 4 can be centrally located on one first sidewall 18 or distributed across two first sidewalls 18. No limitation is made here, and those skilled in the art can adjust them according to actual needs. It is understood that when multiple connection ports 4 are spaced apart along the second direction Y on one of the first sidewalls 18, not only can the arrangement of the connection ports 4 be more compact, which is beneficial for miniaturization of the flow channel structure, but it can also further reduce the processing difficulty of the flow channel structure.

[0082] Furthermore, the connection port 4 is connected to the second flow channel, the connection port 4 has a first center line, and the second flow channel connected to the connection port 4 has a second center line, the second center line and the first center line are collinear.

[0083] In this embodiment, since the connection port 4 is connected to the second flow channel, i.e., the connection port 4 is concentrated in the second layer flow channel 3, the processing difficulty of the flow channel structure can be further reduced. In addition, since the first center line of the connection port 4 is collinear with the second center line of the second flow channel, the flow direction of the fluid entering the second flow channel through the connection port 4 does not change, thereby further reducing the flow resistance of the fluid.

[0084] In one embodiment, such as Figures 4 to 5 As shown, the second flow channel includes second flow channels A31, B32, C33, D34, E35, and F36, which are sequentially spaced along the second direction Y. Second flow channel A31 is connected to first flow channels A21 and B22, second flow channel B32 is connected to first flow channel A21, second flow channel C33 is connected to first flow channels A21 and B22, and second flow channels D34, E35, and F36 are all connected to first flow channel C23. In addition, the connection port 4 includes a first connection port 41, a second connection port 42, a third connection port 43, a fourth connection port 44, a fifth connection port 45, and a sixth connection port 46 arranged sequentially at intervals along the second direction Y. The first connection port 41 is connected to the second flow channel A31, the second connection port 42 is connected to the second flow channel B32, the third connection port 43 is connected to the second flow channel C33, the fourth connection port 44 is connected to the second flow channel D34, the fifth connection port 45 is connected to the second flow channel E35, and the sixth connection port 46 is connected to the second flow channel F36. The connection ports 4 can be used to connect heat exchange components such as the condenser 83, the evaporator 82, the gas separator 85, and the compressor 81.

[0085] Furthermore, the connection port 4 has a first centerline, which is perpendicular to the first sidewall 18. And / or, the second flow channel has a second centerline, which is perpendicular to the first sidewall 18.

[0086] In practical applications, the body 1 is roughly rectangular. The first sidewall 18 of the body 1 is parallel to the first direction X. When the first center line of the connection port 4 is perpendicular to the first sidewall 18, and / or the second center line of the second flow channel is perpendicular to the first sidewall 18, the processing difficulty of the flow channel structure can be further reduced.

[0087] In some optional embodiments of this application, N second flow channels are arranged in parallel. This simplifies the structure of the second-layer flow channel 3 and helps to reduce the processing difficulty of the flow channel structure.

[0088] Furthermore, the body 1 includes two second sidewalls 19 disposed opposite each other along a second direction Y, the second direction Y being perpendicular to the first direction X; the second flow channel is parallel to at least one of the second sidewalls 19. It is understood that the two second sidewalls 19 are located between the two first sidewalls 18, and together with the two first sidewalls 18, form the sidewalls of the body 1.

[0089] In practical applications, the body 1 is roughly rectangular in shape, and the second sidewall 19 of the body 1 is parallel to the first direction X. When the second flow channel is parallel to at least one of the second sidewalls 19, the processing difficulty of the flow channel structure can be further reduced.

[0090] In some alternative embodiments of this application, such as Figure 3 , Figure 5 As shown, the P first flow channels are straight, where P≤M. This allows for a shorter flow channel length per individual first flow channel, meaning a shorter distance the fluid travels within the first flow channel, thereby further reducing flow resistance.

[0091] It should be noted that a straight flow channel refers to a structure in which fluid can flow in a straight direction within the channel. In one embodiment, such as... Figure 3 As shown Figure 5 As shown, the first flow channel A21 and the second flow channel B32 in the first layer flow channel 2, as well as the six second flow channels in the second layer flow channel 3, are all straight flow channels, which can reduce the fluid flow resistance of the flow channel structure and help improve the thermal management efficiency of the vehicle.

[0092] In some alternative embodiments of this application, such as Figure 3 As shown, the first flow channel includes at least two straight flow channels, and the at least two straight flow channels intersect at a point with a rounded transition. Thus, when at least two straight flow channels intersect, by setting the intersection to a rounded transition, i.e., making the corner of the intersection smoother, the fluid can be guided to flow more smoothly, which helps maintain fluid stability, reduces unnecessary energy loss, and further reduces fluid flow resistance.

[0093] It should be noted that the embodiments of this application do not limit the number of intersecting straight flow channels, and those skilled in the art can adjust them according to actual needs. In one embodiment, such as Figure 3 As shown, the first flow channel C23 of the first layer flow channel 2 includes three intersecting straight flow channels. In addition, in order to further reduce the flow resistance of the fluid when passing through the first flow channel C23, the two straight flow channels near the edge of the body 1 are distributed at an obtuse angle, that is, the angle between the center lines of the two straight flow channels is greater than 90°, which can reduce the local loss of the fluid at the intersection and help reduce the fluid flow resistance.

[0094] In some optional embodiments of this application, the body 1 has a first surface 11 perpendicular to the first direction X, and the first surface 11 is provided with a flow channel groove; the flow channel structure also includes a connecting plate 6, which is disposed on the side of the body 1 close to the first surface 11, and the connecting plate 6 and the flow channel groove enclose to form a first layer of flow channel 2.

[0095] In this embodiment, a flow channel groove is provided on the first surface 11 of the body 1, and a connecting plate 6 is provided on the side of the body 1 close to the first surface 11. In this way, the connecting plate 6 and the flow channel groove can be enclosed to form a first layer of flow channel 2. Compared with providing the first layer of flow channel 2 inside the body 1, the structure of the first layer of flow channel 2 is simple, easy to process, and helps to reduce the processing difficulty of the flow channel structure.

[0096] It should be noted that the second layer flow channel 3 located inside the body 1 can be processed and formed by machining, forging or a combination of machining and forging. The flow channel groove located on the surface of the body 1 can be formed by forging.

[0097] In some optional embodiments of this application, the flow channel includes a channel wall that protrudes from the first surface 11 along a first direction X; the side of the channel wall facing away from the first surface 11 is connected to the connecting plate 6.

[0098] In this embodiment, since the groove wall protrudes from the first surface 11 along the first direction X, the groove walls of two adjacent flow channel grooves are spaced apart, thereby isolating the two adjacent flow channel grooves from each other and effectively preventing heat transfer between different modes of the thermal management module. Furthermore, the thickness of the body 1 along the first direction X can be reduced, which is beneficial for the lightweighting of the flow channel structure.

[0099] It should be noted that, in order for the flow channel to meet the burst strength requirements, the thickness of the channel wall should be greater than or equal to 4 mm.

[0100] In some optional embodiments of this application, the connecting plate 6 is provided with a communication port, which is positioned opposite at least a portion of the flow channel groove. The communication port is used to connect the heat exchange component. In this way, by providing the communication port, fluid can flow between the flow channel groove and the heat exchange component, thereby achieving heat exchange.

[0101] In one embodiment, the connection ports include a first connection port 61 and a second connection port 62. The first connection port 61 corresponds to the position of the channel groove that encloses the first flow channel B22, and the second connection port 62 corresponds to the position of the channel groove that encloses the first flow channel C23. This allows the first flow channels B22 and C23 to be connected to the heat exchange equipment, thereby enabling different operating modes of the thermal management module. The heat exchange component connected to the connection ports is a heat exchanger 7, which functions as both a plate heat exchanger 7 and a water-cooled condenser 83. The heat exchanger 7 includes a first air pipe 71 and a second air pipe 72 connected to the flow channel structure, and a first water pipe 73 and a second water pipe 74 connected to an external water supply device (such as the water tank of an engine cooling system). Specifically, the first air pipe 71 is connected to the first connection port 61, and the second air pipe 72 is connected to the second connection port 62. In both air conditioning cooling and battery cooling modes, heat exchanger 7 acts as a water-cooled condenser 83, exchanging heat with the external water supply equipment. In both air conditioning heating and battery heating modes, heat exchanger 7 acts as a plate heat exchanger 7, exchanging heat with the external water supply equipment. This heat exchanger 7 can utilize existing products, which simplifies the structure of the thermal management module, reduces the number of flow channels in the flow channel structure, and avoids system pressure and heat loss.

[0102] In practical applications, the first surface 11 is provided with multiple connecting parts 13, and the flow channel structure is connected to the heat exchange component through the connecting parts 13. In one embodiment, the connecting part 13 is a threaded sleeve, and the reliable connection between the flow channel structure and the heat exchange component, i.e., the heat exchanger 7, is achieved by connecting the bolts to the threaded sleeve.

[0103] In some optional embodiments of this application, the first surface 11 is provided with one of a positioning protrusion 63 or a positioning recess 111; the connecting plate 6 is provided with the other of a positioning protrusion 63 or a positioning recess 111 on the side near the first surface 11, and the positioning protrusion 63 is embedded in the positioning recess 111.

[0104] In this embodiment, the positioning protrusion 63 and positioning recess 111 are provided. By embedding the positioning protrusion 63 into the positioning recess 111, the positioning of the connecting plate 6 can be achieved, avoiding leakage in the flow channel structure caused by incorrect installation during the assembly of the body 1 and the connecting plate 6. On the other hand, it reduces the requirements for tooling fixtures during the assembly of the body 1 and the connecting plate 6, which helps to reduce production line costs.

[0105] It should be noted that the positioning protrusions 63 and positioning recesses 111 in the embodiments of this application should have the same number and be positioned relative to each other. In one embodiment, two positioning protrusions 63 and two positioning recesses 111 are provided, with one positioning protrusion 63 corresponding to one positioning recess 111. Furthermore, the accompanying drawings of the embodiments of this application only show the case where the positioning recess 111 is provided on the first surface 11 and the positioning protrusion 63 is provided on the connecting plate 6. In practical applications, those skilled in the art can also provide the positioning recess 111 on the connecting plate 6 and the positioning protrusion 63 on the first surface 11. This is not limited here, and those skilled in the art can adjust it according to actual needs. In addition, in one embodiment, the connecting plate 6 and the body 1 are connected by furnace welding.

[0106] In some optional embodiments of this application, the body 1 has a second surface 17 perpendicular to the first direction X; the body 1 is also provided with a plurality of mounting holes 5, which are disposed on the second surface 17 and communicate with the second layer flow channel 3, and are used to install control valves. Thus, since the mounting holes 5 communicate with the second layer flow channel 3, by placing the control valve in the mounting holes 5, the flow direction and flow rate of fluid between the second layer flow channel 3 and the first layer flow channel 2 can be controlled to achieve different operating modes of the thermal management module.

[0107] It should be noted that the second surface 17 and the first surface 11 are two surfaces of the body 1 that are arranged opposite to each other along the first direction X. In one embodiment, the control valve includes a solenoid valve (SOV), an electronic expansion valve (EXV), etc., and correspondingly, the mounting hole 5 includes a solenoid valve mounting hole, an electronic expansion valve mounting hole, etc. In one embodiment, the solenoid valve mounting hole includes a first solenoid valve mounting hole 511, a second solenoid valve mounting hole 512, a third solenoid valve mounting hole 513, and a fourth solenoid valve mounting hole 514; the electronic expansion valve mounting hole includes a first electronic expansion valve mounting hole 521, a second electronic expansion valve mounting hole 522, a third electronic expansion valve mounting hole 523, and a fourth electronic expansion valve mounting hole 524. In addition, the thermal management module is usually equipped with various sensors to detect parameters such as fluid temperature and pressure. In one embodiment, the sensor includes a first temperature sensor T1, a second temperature sensor T2, a third temperature sensor T3, a pressure sensor P1, and a pressure-temperature sensor PT1. Correspondingly, the mounting hole 5 also includes a first temperature sensor mounting hole 531, a second temperature sensor mounting hole 532, a third temperature sensor mounting hole 533, a pressure sensor mounting hole 541, and a pressure-temperature sensor mounting hole 551.

[0108] It should be noted that the specific location of the mounting hole 5 for installing various control valves is not specifically limited in the embodiments of this application. Those skilled in the art can make corresponding adjustments according to the overall layout of different vehicles and the layout of each heat exchange component in the thermal management module, so as to meet the thermal management needs of vehicles under different operating conditions.

[0109] In some optional embodiments of this application, a second flow channel communicates with at least one mounting hole 5; the second flow channel has a second center line, and the mounting hole 5 has a third center line, which is perpendicular to the second center line. Thus, during processing, the mounting hole 5 can be machined from top to bottom along the first direction X to ensure communication between the mounting hole 5 and the second flow channel, which helps reduce the processing difficulty of the mounting hole 5.

[0110] Depend on Figure 2 It is known that the connection port 4 is centrally located in the second layer flow channel 3, and the connection port 4 is used to connect with the heat exchange component. Based on this, in some optional embodiments of this application, the first direction X is the vertical direction, and the second layer flow channel 3 is adapted to be located above the first layer flow channel 2. In this way, by setting the second layer flow channel 3 above the first layer flow channel 2, the fluid entering the second layer flow channel 3 from the heat exchange component through the connection port 4 can flow to the first layer flow channel 2 by gravity, which can save energy and reduce the operating cost of the thermal management module. In some optional embodiments of this application, the body 1 is also provided with a hollow area 14, which is located between two adjacent first flow channels and / or two adjacent second flow channels.

[0111] In this embodiment of the application, since a hollow area 14 is provided between two adjacent first flow channels and / or two adjacent second flow channels, on the one hand, heat exchange between the thermal management modules in different modes can be avoided; on the other hand, the fluid structure can be made lightweight.

[0112] In summary, the flow channel structure provided in this application embodiment has at least the following advantages:

[0113] In this embodiment, by setting up a first layer of flow channels and a second layer of flow channels, with the first layer comprising M independent first flow channels and the second layer comprising N independent second flow channels, more flow channels can be set within the main body 1, which is beneficial for improving the flexibility and integration of the flow channel structure. Furthermore, the function of the first layer of flow channels is to connect different second flow channels. Compared to setting one first flow channel connecting all second flow channels, setting multiple first flow channels, with each first flow channel connected to at least two second flow channels, simplifies the structure of the first layer of flow channels and reduces the processing difficulty of the flow channel structure. More importantly, since L of the second flow channels are straight-line flow channels, where L≤N, meaning at least some of the second flow channels are straight-line flow channels, the distance the fluid travels within the second flow channels can be reduced, thereby reducing fluid resistance and improving the vehicle's thermal management efficiency.

[0114] Reference Figures 9 to 11 The diagram shows a structural schematic of a thermal management module provided in an embodiment of this application. (Refer to...) Figure 12 This diagram illustrates the working principle of a thermal management module according to an embodiment of this application. Figures 13 to 14 The diagram shows a structural schematic of another thermal management module provided in an embodiment of this application.

[0115] like Figures 9 to 11 As shown in the embodiments of this application, a thermal management module is also provided, including: a flow channel structure and a control valve as described in any of the above embodiments, wherein the control valve is installed in the flow channel structure.

[0116] It should be noted that in the embodiments of this application, the structure of the flow channel is the same as that of any of the above embodiments, and its beneficial effects are similar, so it will not be described in detail here.

[0117] like Figures 13 to 14 This application also provides another thermal management module, compared to... Figures 9 to 11 The thermal management module has undergone changes in its base dimensions and shape, the arrangement of components (including heat exchangers, control valves, sensors, etc.), and the connection ports on its main body 1. Correspondingly, the arrangement of the first layer flow channel 2 and the second layer flow channel 3 within the flow channel structure has also changed accordingly. Therefore, on the one hand, the thermal management module can be adapted to different vehicle models and accommodate different spatial arrangement requirements by changing its boundary information such as size and shape. On the other hand, different components can be integrated, and the specific structures of the first layer flow channel 2 and the second layer flow channel 3 can be adjusted to match different operating modes of the vehicle's thermal management module. Furthermore, the structural arrangement can be optimized by changing the positions of the components.

[0118] In addition, such as Figure 14 As shown, when the flow channel structure is formed by machining, there may be extra machining holes 15 on the body 1. After machining, a plug 16 is needed to seal the machining holes 15 to improve the sealing performance between the plug 16 and the machining holes 15 and prevent fluid leakage. Specifically, the plug 16 and the machining holes 15 can be welded together.

[0119] In some optional embodiments of this application, the control valve includes at least one of a solenoid valve and an electronic expansion valve. The solenoid valve controls the flow of fluid in the flow channel, enabling the normal operation of the thermal management module. The electronic expansion valve throttles and reduces pressure, regulates flow rate, and controls superheat; it is the core control component of the vehicle's thermal management module. The electronic expansion valve sends a drive signal to the motor via a controller, and the transmission system converts the motor's rotational motion into linear motion, which in turn drives the valve needle to move up and down, thus changing the valve opening and regulating the fluid flow rate.

[0120] Furthermore, the control valve is installed in the second flow channel, and the control valves installed in the same second flow channel are of the same type. Generally, control valves of the same type require roughly the same installation space, such as the opening size of the mounting hole 5. By installing control valves of the same type in the same second flow channel, not only can the installation of the control valve be more compact, which is beneficial to the miniaturization of the flow channel structure, but the structure of the flow channel can also be simplified, which helps to reduce the processing difficulty of the flow channel structure. In one embodiment, such as Figure 2 As shown, both the second flow channel A31 and the second flow channel C33 are equipped with two control valves, and both control valves are solenoid valves.

[0121] In one embodiment, such as Figure 10 As shown, the solenoid valves include a first solenoid valve SOV1, a second solenoid valve SOV2, a third solenoid valve SOV3, and a fourth solenoid valve SOV4. The electronic expansion valves include a first electronic expansion valve EXV1, a second electronic expansion valve EXV2, a third electronic expansion valve EXV3, and a fourth electronic expansion valve EXV4. Different modes of the thermal management module can be switched by opening and closing different solenoid valves and electronic expansion valves. Combined with... Figure 12 The following describes in detail the eight modes of the thermal management module in the embodiments of this application.

[0122] In this embodiment, the heat exchange components include a compressor 81, an evaporator 82, a condenser 83, a heat exchanger 7, a battery pack direct cooling plate 84, and a gas separator 85.
