[0053] To make the objectives, features, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0054] Currently, the engine and the three electric components are located in different parts of the vehicle, which leads to complex pipeline connections, long pipeline extension distances, and cumbersome assembly.
[0055] To address this issue, some vehicles are equipped with a thermal management integrated module. This module includes a flow channel plate containing several flow channels and multiple interfaces communicating with these channels. By connecting the engine coolant circuit and the electric drive system coolant circuit to the flow channel plate, heat exchange between the engine coolant and the electric drive system coolant is achieved through a water-to-water heat exchanger on the flow channel plate.
[0056] Because of the significant temperature difference between the engine coolant and the electric drive system coolant, and because they are completely different media, uncontrollable heat exchange can easily occur between the engine coolant and the electric drive system coolant at the inlet of the water-to-water heat exchanger in the flow channel plate, especially when they are close together. This leads to a decrease in the accuracy of thermal management control. Furthermore, the flow channel plate is typically composed of two plates joined together by welding or fasteners. Therefore, if the seal at the joint fails, the engine coolant and the electric drive system coolant will cross-contaminate. Whether engine coolant enters the electric drive system coolant circuit or vice versa, it will prevent the vehicle from operating normally.
[0057] In view of this, embodiments of this application provide a thermal management integrated module and a vehicle to solve the problems of uncontrollable heat exchange and coolant leakage that easily occur in vehicle thermal management modules in related technologies.
[0058] As shown in Figures 1, 2, 6, and 7, the thermal management integrated module according to an embodiment of this application includes a flow channel plate 10 and a heat exchanger 40. The flow channel plate 10 includes multiple flow channels 20 and multiple interfaces 30. The multiple flow channels 20 include a first flow channel 21 and a second flow channel 22, and the multiple interfaces 30 include a first interface 31 and a second interface 32. The first flow channel 21 communicates with the first interface 31, and the second flow channel 22 communicates with the second interface 32. The heat exchanger 40 is disposed on the flow channel plate 10 and includes a first channel and a second channel for mutual heat exchange. The first interface 31 communicates with the first channel, and the second interface 32 communicates with the second channel. Further, a gap d exists between the portion of the first flow channel wall 211 of the first flow channel 21 at the first interface 31 and the portion of the second flow channel wall 221 of the second flow channel 22 at the second interface 32.
[0059] Using the technical solution of this application embodiment, the heat exchange medium in the first flow channel 21 flows into the first channel of the heat exchanger 40 through the first interface 31, and the heat exchange medium in the second flow channel 22 flows into the second channel of the heat exchanger 40 through the second interface 32, thereby realizing heat exchange within the heat exchanger 40. Simultaneously, a gap d exists between the portions of the first flow channel wall 211 of the first flow channel 21 and the second flow channel wall 221 of the second flow channel 22 at the first interface 31 and the second interface 32, respectively. That is, before entering the heat exchanger 40, the first flow channel wall 211 and the second flow channel wall 221 are isolated from each other. This gap d allows air to isolate the first interface 31 and the second interface 32, thereby reducing uncontrollable heat exchange of the medium in the first flow channel 21 and the second flow channel 22. Furthermore, even if the first flow channel 21 or the second flow channel 22 experiences sealing failure or leakage, the coolant will flow into the gap d, preventing direct liquid leakage. Therefore, the technical solution of this application embodiment solves the problems of uncontrollable heat exchange and liquid leakage that easily occur in vehicle thermal management modules in related technologies.
[0060] As shown in Figures 1, 4, and 6, the flow channel plate 10 has an overall plate-like structure with an internal cavity. Ribs form the flow channel walls within the cavity, and multiple flow channels 20 are formed within the flow channel plate 10 for the heat exchange medium to flow through. As shown in Figure 2, the flow channel plate 10 has multiple interfaces 30, each interface 30 communicating with a corresponding flow channel 20. Interfaces 30 are used for connection to external piping or for connection to the working ports of thermal management components.
[0061] Thermal management components may include heat exchangers, reversing valves, check valves, various valve components, and sensors, etc.
[0062] As shown in Figures 2 and 6, the flow channel 20 includes a first flow channel 21 and a second flow channel 22, and the interface 30 includes a first interface 31 and a second interface 32. When the heat exchanger 40 is assembled on the flow channel plate 10, the first interface 31 is connected to the first channel of the heat exchanger 40, and the second interface 32 is connected to the second channel of the heat exchanger 40. Referring to Figure 1, the first heat exchange medium in the first flow channel 21 can flow into the first channel through the first interface 31, and the second heat exchange medium in the second flow channel 22 can flow into the second channel through the second interface 32, thereby enabling heat exchange between the first and second heat exchange media within the heat exchanger 40.
[0063] Optionally, the first heat exchange medium in the first flow channel 21 and the second heat exchange medium in the second flow channel 22 in this embodiment can be the same medium or different media.
[0064] In this embodiment, the first heat exchange medium in the first flow channel 21 can be engine coolant, and the second heat exchange medium in the second flow channel 22 can be the coolant for the electric drive system. That is, the first heat exchange medium and the second heat exchange medium are different media.
[0065] Optionally, the heat exchanger 40 in the embodiments of this application is a liquid-liquid heat exchanger.
[0066] As shown in Figures 1 and 2, due to the small overall volume of the heat exchanger 40, the various working ports of the heat exchanger 40 are arranged close together, and therefore the first port 31 and the second port 32 are also arranged close together. Because the temperature difference between the first heat exchange medium and the second heat exchange medium is large before they exchange heat through the heat exchanger 40, uncontrollable heat exchange can easily occur at the first port 31 and the second port 32 before they enter the heat exchanger 40, leading to a decrease in the control accuracy of thermal management.
[0067] Therefore, as shown in Figures 6 and 7, a gap d exists between the portion of the first flow channel wall 211 of the first flow channel 21 at the first interface 31 and the portion of the second flow channel wall 221 of the second flow channel 22 at the second interface 32. In this way, the first interface 31 and the second interface 32 are isolated by air within the gap d, greatly slowing down the heat conduction between the first and second heat exchange media, thus eliminating uncontrolled heat exchange between the first and second heat exchange media before they enter the heat exchanger 40.
[0068] Furthermore, when the first heat exchange medium and the second heat exchange medium are different media, and when the first flow channel wall 211 fails to seal, the first heat exchange medium will leak into the gap d instead of flowing directly into the second flow channel wall 221. Correspondingly, when the second flow channel wall 221 fails to seal, the second heat exchange medium will leak into the gap d instead of flowing directly into the first flow channel wall 211. That is, the aforementioned gap d can also prevent cross-contamination between the first and second heat exchange media.
[0069] As shown in Figures 7 and 12, in the technical solution of this application embodiment, the first interface 31 is located at the end of the first flow channel 21, and the second interface 32 is located at the end of the second flow channel 22. The end of the first flow channel 21 is spaced apart from the second flow channel wall 221, and the end of the second flow channel 22 is spaced apart from the first flow channel wall 211.
[0070] Specifically, by setting the end of the first flow channel 21 at a distance from the second flow channel wall 221, the first interface 31 and the second flow channel 22 as a whole have a certain gap, thereby further reducing the situation of uncontrollable heat exchange between the first heat exchange medium and the second heat exchange medium.
[0071] Correspondingly, by setting the end of the second flow channel 22 at a distance from the first flow channel wall 211, the second interface 32 and the entire first flow channel 21 have a certain gap, which further reduces the possibility of uncontrollable heat exchange between the first heat exchange medium and the second heat exchange medium.
[0072] As shown in Figure 7, since the first flow channel wall 211 and the second flow channel wall 221 are arranged at intervals, a first reinforcing rib 50 is connected between the first flow channel wall 211 and the second flow channel wall 221, thereby strengthening the structural strength of the first flow channel wall 211 and the second flow channel wall 221.
[0073] As shown in Figures 2, 4, 6, and 12, in the technical solution of this application embodiment, there are two first flow channels 21, and two first interfaces 31 are respectively connected to the two first flow channels 21. The plurality of interfaces 30 also includes two third interfaces 33, which are respectively connected to the two first flow channels 21 and are used to connect to the engine cooling circuit.
[0074] Furthermore, as can be seen from Figures 4 and 6, for each first flow channel 21, the first interface 31 and the third interface 33 are located at the two ends of the first flow channel 21, respectively.
[0075] Specifically, the first flow channel 21 is used to introduce high-temperature engine coolant. Of the two third interfaces 33, one is an engine coolant inlet and the other is an engine coolant outlet. One of the first flow channels 21 is used to allow the engine coolant to enter the heat exchanger 40 for heat exchange, and the engine coolant flows out through the other first flow channel 21 after heat exchange.
[0076] During heat exchange, the engine coolant enters one of the first flow channels 21 and then flows into the first flow channel of the heat exchanger 40 through one of the first ports 31. After heat exchange in the heat exchanger 40, the engine coolant flows into the other first flow channel 21 through the other first port 31.
[0077] As shown in Figures 1, 2, 4, 6, and 12, in the technical solution of this application embodiment, there are two second flow channels 22. The plurality of interfaces 30 also includes two fourth interfaces 34 and two fifth interfaces 35, and the plurality of flow channels 20 also includes a third flow channel 23 and a fourth flow channel 24. The two fourth interfaces 34 are respectively connected to the two second flow channels 22, and the two fifth interfaces 35 are respectively connected to the third flow channel 23 and the fourth flow channel 24.
[0078] Furthermore, a four-way valve 60 is also provided on the flow channel plate 10. The two fourth ports 34 and the two fifth ports 35 are all connected to the four-way valve 60. The third flow channel 23 and the fourth flow channel 24 are used to connect to one or more of the following cooling circuits: motor cooling circuit, battery cooling circuit and electronic control system cooling circuit.
[0079] Specifically, of the two second flow channels 22, one second flow channel 22 is used to allow the second heat exchange medium to enter the heat exchanger 40, and the other second flow channel 22 is used to allow the second heat exchange medium after heat exchange to flow out of the heat exchanger 40. That is, the second heat exchange medium exchanges heat with the first heat exchange medium inside the heat exchanger 40. As can be seen from Figure 12, the second interface 32 and the fourth interface 34 are located at the two ends of the second flow channel 22, respectively.
[0080] Furthermore, a second heat exchange medium is introduced into both the third flow channel 23 and the fourth flow channel 24, with the third flow channel 23 being an outflow channel and the fourth flow channel 24 being an inflow channel. In this embodiment, the third flow channel 23 and the fourth flow channel 24 are connected to the three-electric cooling circuit, meaning that the coolant flowing in the third flow channel 23 and the fourth flow channel 24 is the three-electric system coolant.
[0081] It should be noted that "three electrics" refers to the electric motor, battery, and electronic control system.
[0082] In some implementations, the third flow channel 23 and the fourth flow channel 24 may be connected only to the motor cooling circuit, or only to the battery cooling circuit, or only to the electronic control system cooling circuit.
[0083] In some embodiments, the third flow channel 23 and the fourth flow channel 24 may also be connected to the motor cooling circuit and the battery cooling circuit, or to the battery cooling circuit and the electronic control system cooling circuit, or to the motor cooling circuit and the electronic control system cooling circuit.
[0084] In some implementations, the third flow channel 23 and the fourth flow channel 24 may be connected to the motor cooling circuit, the battery cooling circuit, and the electronic control system cooling circuit.
[0085] As shown in Figure 12, the two fifth interfaces 35 are located at the ends of the third flow channel 23 and the fourth flow channel 24, respectively.
[0086] As can be seen from Figure 12, the two fourth ports 34 and the two fifth ports 35 are arranged in a cross shape. When the four-way valve 60 is installed on the flow channel plate 10, the two fourth ports 34 and the two fifth ports 35 are respectively connected to the four working ports of the four-way valve 60. Therefore, the four-way valve 60 can reverse the flow of coolant in the three-electric system.
[0087] In this embodiment, the four-way valve 60 is used to control whether the coolant of the three-electric system exchanges heat with the engine coolant.
[0088] Specifically, when heat exchange is required, the four-way valve 60 controls one of the fifth ports 35 to connect with one of the fourth ports 34, and the other fifth port 35 to the other fourth port 34. At this time, the coolant of the three-electric system flows into the heat exchanger 40 through the fourth flow channel 24 and one of the second flow channels 22. After heat exchange, the coolant of the three-electric system flows out from the other second flow channel 22, and then is discharged from the flow channel plate 10 through the third flow channel 23.
[0089] When heat exchange is not required, the four-way valve 60 controls the connection of the two fifth ports 35 and the two fourth ports 34. At this time, the coolant of the three-electric system is directly discharged from the flow channel plate 10 through the fourth flow channel 24 and the third flow channel 23, that is, heat exchange does not occur in the heat exchanger 40.
[0090] As shown in Figures 2, 4, 6 and 12, in the technical solution of the embodiment of this application, the multiple interfaces 30 also include a sixth interface 36, which is connected to the third flow channel 23 and is used to discharge the heat exchange medium from the flow channel plate 10.
[0091] As shown in Figure 12, the fifth interface 35 and the sixth interface 36 are located at opposite ends of the third flow channel 23. The sixth interface 36 is used for external piping, allowing the coolant from the three-electric system, whether after heat exchange or without heat exchange, to flow back into the cooling circuit of the three-electric system.
[0092] As shown in Figures 1, 2, 4, 6, and 12, in the technical solution of this embodiment, the multiple flow channels 20 further include a fifth flow channel 25 and a sixth flow channel 26, and the multiple interfaces 30 further include a seventh interface 37, an eighth interface 38, a ninth interface 39, a tenth interface 310, and an eleventh interface 311. The seventh interface 37 is connected to the fourth flow channel 24, the eighth interface 38 and the ninth interface 39 are both connected to the fifth flow channel 25, and the tenth interface 310 and the eleventh interface 311 are both connected to the sixth flow channel 26. A three-way valve 70 is also provided on the flow channel plate 10, and the seventh interface 37, the eighth interface 38, and the tenth interface 310 are all connected to the three-way valve 70. The ninth interface 39 and the eleventh interface 311 are used to allow the heat exchange medium to flow into the flow channel plate 10.
[0093] Specifically, in this embodiment, both the fifth flow channel 25 and the sixth flow channel 26 are used to allow the coolant of the three-electric system to enter the flow channel plate 10. As shown in Figure 12, the eighth interface 38 and the ninth interface 39 are located at both ends of the fifth flow channel 25, and the tenth interface 310 and the eleventh interface 311 are located at both ends of the sixth flow channel 26. Among them, the ninth interface 39 and the eleventh interface 311 are inlets.
[0094] As can be seen from Figure 12, the eighth port 38, the seventh port 37, and the tenth port 310 are arranged in a straight line, with the seventh port 37 located between the eighth port 38 and the tenth port 310. When the three-way valve 70 is installed on the flow channel plate 10, the eighth port 38, the seventh port 37, and the tenth port 310 are respectively connected to the three working ports of the three-way valve 70.
[0095] In this embodiment, the three-way valve 70 is used to selectively connect the fifth flow channel 25 and the sixth flow channel 26 with the fourth flow channel 24.
[0096] Specifically, when the three-way valve 70 switches to connect the eighth port 38 and the seventh port 37, the fifth flow channel 25 is connected to the fourth flow channel 24, and the coolant of the three-electric system in the fifth flow channel 25 can enter the heat exchanger 40 for heat exchange through the fourth flow channel 24 and the second flow channel 22.
[0097] When the three-way valve 70 switches to connect the tenth port 310 and the seventh port 37, the sixth flow channel 26 is connected to the fourth flow channel 24, and the coolant of the three-electric system in the sixth flow channel 26 can enter the heat exchanger 40 for heat exchange through the fourth flow channel 24 and the second flow channel 22.
[0098] As shown in Figures 1, 2, 4, 6, and 12, in the technical solution of this application embodiment, a one-way valve 80 is provided on the flow channel plate 10, the multiple interfaces 30 also include a twelfth interface 312, and the multiple flow channels 20 also include a seventh flow channel 27. The one-way valve 80 is connected to the sixth flow channel 26, and the twelfth interface 312 is connected to the seventh flow channel 27. The one-way valve 80 is used to allow the heat exchange medium to flow unidirectionally from the eleventh interface 311 to the twelfth interface 312.
[0099] Specifically, the function of the seventh flow channel 27 is to partially divert the coolant entering the three-electric system from the eleventh port 311. Part of the coolant entering the three-electric system from the eleventh port 311 flows into the sixth flow channel 26, and the other part flows into the seventh flow channel 27 after passing through the one-way valve 80, and finally exits from the flow channel plate 10 through the twelfth port 312.
[0100] As shown in Figure 13, in the technical solution of this application embodiment, the multiple flow channels 20 include a high-temperature flow channel 201 and a low-temperature flow channel 202. The high-temperature flow channel 201 is used to connect with the engine cooling circuit, and the low-temperature flow channel 202 is used to connect with one or more of the following cooling circuits: the motor cooling circuit, the battery cooling circuit, and the electronic control system cooling circuit.
[0101] The high-temperature flow channel 201 and the low-temperature flow channel 202 are separated by a heat exchanger 40.
[0102] Specifically, in this embodiment, the high-temperature flow channel 201 carries engine coolant with a relatively high temperature (e.g., 100°C to 120°C), while the low-temperature flow channel 202 carries coolant for the electric drive system with a relatively low temperature (e.g., around -40°C). If the two coolants exchange heat at locations other than the heat exchanger 40, uncontrollable heat exchange will occur. Uncontrollable heat exchange will affect the control accuracy of thermal management, and this uncontrollable heat exchange should be minimized or eliminated as much as possible.
[0103] As can be seen from Figure 13, the dashed area where the high-temperature flow channel 201 is located and the dashed area where the low-temperature flow channel 202 is located are separated by the heat exchanger 40. Therefore, the engine coolant and the three-electric system coolant are separated, reducing the heat exchange between the two in the parts other than the heat exchanger 40, and alleviating the situation of uncontrollable heat exchange.
[0104] In this embodiment of the application, the high-temperature flow channel 201 includes two first flow channels 21.
[0105] In this embodiment of the application, the low-temperature flow channel 202 includes two second flow channels 22, a third flow channel 23, a fourth flow channel 24, a fifth flow channel 25, a sixth flow channel 26, and a seventh flow channel 27.
[0106] As shown in Figure 14, in the technical solution of this application embodiment, the flow channel plate 10 has a first direction, a second direction, and a third direction that are perpendicular to each other, and the first direction and the second direction form a preset plane. A plurality of flow channels 20 include a first interlaced flow channel 203 and a second interlaced flow channel 204. The first interlaced flow channel 203 extends within the preset plane, and the second interlaced flow channel 204 includes an interlacing portion 2041. The projection of the interlacing portion 2041 onto the preset plane at least partially coincides with the first interlaced flow channel 203. Furthermore, the extending direction of the interlacing portion 2041 has a first preset angle α with the preset plane.
[0107] First, it should be noted that the flow channel plate 10 includes a first plate 13 and a second plate 14, which are interlocked to form the flow channel plate 10. Referring to Figure 2, the aforementioned preset plane refers to the plane containing the interlocking surfaces of the first plate 13 and the second plate 14. The first direction and the second direction are two perpendicular directions on the interlocking surface. In this embodiment, the first direction is the width direction of the flow channel plate 10, the second direction is the length direction of the flow channel plate 10, and the third direction is the thickness direction of the flow channel plate 10.
[0108] Of course, those skilled in the art can also change the specific orientations represented by the first direction, the second direction, and the third direction according to actual needs.
[0109] Furthermore, the plurality of flow channels 20 includes a first interlaced flow channel 203 and a second interlaced flow channel 204, wherein “interlaced flow channel” means that the projections of the first interlaced flow channel 203 and the second interlaced flow channel 204 on a preset plane have overlapping portions, as shown in the schematic diagram of the dashed shaded box in FIG15.
[0110] Furthermore, the second staggered flow channel 204 includes an staggered portion 2041, which means that the second staggered flow channel 204 intersects with the first staggered flow channel 203 in this portion, and the second staggered flow channel 204 does not intersect with the first staggered flow channel 203 in the remaining portion.
[0111] In this embodiment, the interlacing portion 2041 intersects the first interlacing flow channel 203 at a 90° angle. This 90° intersection means that when the interlacing portion 2041 and the first interlacing flow channel 203 are projected onto the aforementioned preset plane, the projection of the interlacing portion 2041 is arranged at a 90° angle to the projection of the first interlacing flow channel 203. Furthermore, as can be seen from Figure 14, the extending direction of the interlacing portion 2041 has a first preset angle α with the aforementioned preset plane, that is, the interlacing portion 2041 is inclined relative to the flow channel plate 10.
[0112] In related technologies, the interfaces of the flow channel plates for thermal management integrated modules are typically set to be perpendicular to each other, including both horizontal and vertical orientations. This design facilitates drafting after casting. If the flow channels intersect during the design process, the following two methods are usually used to resolve the issue.
[0113] Method 1: The flow channel plate is designed as a double-layer structure, with two staggered flow channels, one of which is located in the upper layer and the other in the lower layer.
[0114] Method 2: Modify the position of the entrance or exit and cancel the interlacing part (that is, cancel the interlacing part 2041 in Figure 15).
[0115] However, in traditional design methods, the first approach increases the thickness of the flow channel plate, increasing costs and space occupied in the vehicle; the second approach restricts the location of the interface, greatly reducing design flexibility.
[0116] Therefore, in this embodiment, the interlacing portion 2041 is configured such that its extending direction has a first preset angle α with the preset plane. That is, the interlacing portion 2041 is arranged in an oblique insertion manner. This arrangement has the following two advantages.
[0117] 1. Even when the flow channel plate 10 is only one layer, the first staggered flow channel 203 and the second staggered flow channel 204 can still have staggered parts, and the flow channel plate 10 does not need to be designed as two layers.
[0118] 2. By rotating the interlaced portion 2041 about a third direction as the axis of rotation, the orientation of the interlaced portion 2041 can be changed, which is beneficial for the flexible arrangement of the interface 30 compared to the vertically set interface 30.
[0119] As shown in Figure 14, in this embodiment of the application, the first interlaced flow channel 203 is the seventh flow channel 27, and the second interlaced flow channel 204 is the fifth flow channel 25. Furthermore, as shown in Figure 2, the end of the interlaced portion 2041 forms the ninth interface 39, which is in the form of an oblique insertion.
[0120] In some embodiments not shown, the first staggered flow channel 203 and the second staggered flow channel 204 can be any two flow channels 20 described above, and the ends of the staggered portions 2041 can also form any of the interfaces 30 described above.
[0121] Optionally, the first preset angle α is in the range of 30° to 60°.
[0122] For example, the first preset angle α can be 30°, 35°, 40°, 45°, 50°, 55°, or 60°, or any value between the two values.
[0123] Preferably, the first preset angle α is 45°.
[0124] As shown in Figures 6, 8 and 12, in the technical solution of this application embodiment, the inner wall of the first interlaced flow channel 203 is provided with a second reinforcing rib 2031 at the position where it overlaps with the interlaced portion 2041.
[0125] Specifically, at the overlap position of the first interlaced flow channel 203 and the interlaced portion 2041, the inner wall of the first interlaced flow channel 203 will be thinned. In order to ensure the strength of the flow channel wall at the overlap position, a second reinforcing rib 2031 is provided at the overlap position.
[0126] As shown in Figures 1 to 3 and Figure 16, in the technical solution of this application embodiment, the flow channel plate 10 is provided with a first opening 301 and a second opening 302. Both the first opening 301 and the second opening 302 are connected to the first interlaced flow channel 203. The first opening 301 and the second opening 302 are offset in the third direction. The extension direction of the first interlaced flow channel 203 has a second preset angle b with the preset plane, and in the third direction, the two opposing inner walls of the first interlaced flow channel 203 are arranged parallel to each other.
[0127] Specifically, as shown in Figure 16, the first port 301 and the second port 302 are located on both sides of the staggered portion 2041. In the third direction, the first port 301 and the second port 302 are staggered, and the second port 302 is located below the first port 301. Therefore, the first staggered flow channel 203 extends at an angle.
[0128] Because the staggered portion 2041 is inserted at an angle, the thickness of the flow channel plate 10 and each flow channel 20 is slightly increased. For the conventional design of the first staggered flow channel 203, see Figure 17. Along the direction shown in Figure 17, the upper wall of the first staggered flow channel 203 extends at an angle, and the lower wall of the first staggered flow channel 203 extends in an "L" shape. This causes a sudden change in the flow area of the first staggered flow channel 203, which is detrimental to the flow stability of the heat exchange medium.
[0129] Therefore, in this embodiment, in the third direction, the two opposing inner walls of the first staggered flow channel 203 are arranged in parallel, that is, the upper and lower wall surfaces of the first staggered flow channel 203 are arranged in parallel in Figure 16. This ensures that the flow area within the first staggered flow channel 203 remains consistent, which is beneficial to the flow stability of the heat exchange medium.
[0130] As can be seen from Figures 1, 2 and 16, the first port 301 is also the twelfth port 312 mentioned above, and the second port 302 is used to install the one-way valve 80 mentioned above.
[0131] In some embodiments not shown, the first port 301 and the second port 302 can form any of the above-mentioned interfaces 30, or form a port structure for mounting other components.
[0132] As shown in Figure 14, in the technical solution of this application embodiment, the flow channel plate 10 has a first direction, a second direction, and a third direction that are perpendicular to each other, and the first direction and the second direction form a preset plane. At least a portion of the flow channel 20 extends within the preset plane, and at least a portion of the interface 30 extends in a direction that has a third preset angle c with the preset plane.
[0133] Specifically, as shown above, when the interface 30 is in an oblique insertion form, the interface 30 rotates around a third direction as its rotation axis, which can change the orientation of the interface 30. Compared with a vertically arranged interface 30, this allows for more flexible arrangement of the interface 30's position. Therefore, in this embodiment, even if the flow channels 20 do not form an interlaced pattern, its interface 30 can still be set in an oblique form.
[0134] Optionally, the third preset angle c is the same as the first preset angle a mentioned above.
[0135] Optionally, the third preset angle c is in the range of 30° to 60°.
[0136] For example, the third preset angle c can be 30°, 35°, 40°, 45°, 50°, 55° or 60°, etc., or any value between two values.
[0137] Preferably, the third preset angle c is 45°.
[0138] As can be seen from Figures 12 and 14, in this embodiment, the sixth flow channel 26 also forms an oblique insertion form at the eleventh interface 311, so that the extension direction of the eleventh interface 311 has a third preset angle c with the preset plane.
[0139] Of course, in some embodiments not shown, the interface 30 of any of the above-mentioned flow channels 20 can be configured to have a third preset angle c between the extension direction and the preset plane.
[0140] As shown in Figure 4, in the technical solution of this application embodiment, at least some of the flow channels 20 have a flow guiding slope 205 on their bottom walls, and the flow guiding slope 205 is located at the end of the flow channel 20.
[0141] Specifically, the main direction in which the heat exchange medium flows into or out of the flow channel plate 10 is along a third direction (except for the ninth interface 39, the eleventh interface 311, and the twelfth interface 312, as shown in Figure 12), and each flow channel 20 extends within the aforementioned preset plane. This situation causes the heat exchange medium to pass through right-angle corners when flowing into or out of the flow channel plate 10, which increases the flow resistance of the heat exchange medium and increases energy consumption.
[0142] In this embodiment of the application, a guide slope 205 is provided on the bottom wall of the flow channel 20 at the end position, so that the heat exchange medium can flow into the flow channel plate 10 more smoothly and flow out of the flow channel plate 10 more smoothly.
[0143] Those skilled in the art can choose according to actual needs, and can provide guide slopes 205 in all flow channels 20, or only in some flow channels 20.
[0144] Those skilled in the art can choose to provide a guide slope 205 at only one end of the flow channel 20, or provide a guide slope 205 at both ends of the flow channel 20, depending on actual needs.
[0145] As shown in Figure 4, in the technical solution of this application embodiment, at least some of the multiple flow channels 20 are provided with flow divider ribs 206. The flow divider ribs 206 are located at the bends, and / or diameter changes, and / or ends of the flow channels 20.
[0146] Specifically, the flow-diverting ribs 206 can guide and divert the heat exchange medium. Those skilled in the art can adapt the position and shape of the flow-diverting ribs 206 within the flow channel 20 based on the simulation results of the flow medium.
[0147] When the flow divider rib 206 is set at the bend of the flow channel 20, it can prevent the heat exchange medium on both sides from affecting each other, so that the heat exchange medium can pass through the bend more smoothly.
[0148] When the flow divider rib 206 is set at the diameter change of the flow channel 20, it can divert the heat exchange medium and reduce the flow resistance of the heat exchange medium.
[0149] When the flow divider ribs 206 are provided at the end of the flow channel 20, they can reduce the flow resistance of the heat exchange medium flowing in or out.
[0150] Those skilled in the art can choose to provide the flow divider ribs 206 in all the flow channels 20 or only in some of the flow channels 20, depending on actual needs.
[0151] As shown in Figures 1 and 2, in the technical solution of this application embodiment, the flow channel plate 10 has a first side 101 and a second side 102. The first side 101 of the flow channel plate 10 is provided with a plug-in portion 11, and the second side 102 of the flow channel plate 10 is provided with a connecting hole 12 for fasteners to pass through.
[0152] Specifically, in this embodiment of the application, the thermal management integrated module is installed vertically in the front engine compartment of the vehicle. That is, after the flow channel plate 10 is installed in the vehicle, its first side 101 faces upward (or diagonally upward) of the vehicle, and its second side 102 faces downward (or diagonally downward) of the vehicle.
[0153] During assembly, the operator first inserts the flow channel plate 10 into the fixed bracket in the front engine compartment, then places the flow channel plate 10 in the installation position, and finally tightens the fasteners through the connection hole 12 into the front engine compartment.
[0154] As can be seen from Figures 1 and 2, a notch is provided at the corner of the second side 102 of the flow channel plate 10, and an annular sleeve is installed in the notch. The central hole of the annular sleeve forms the aforementioned connecting hole 12.
[0155] As shown in Figures 9 and 10, in the technical solution of the embodiment of this application, the plug-in part 11 includes a protrusion 111 connected to the flow channel plate 10, and a connecting sleeve 112 sleeved outside the protrusion 111. A limiting hook 1112 is provided on the protrusion 111, and the limiting hook 1112 cooperates with the surface of the connecting sleeve 112 away from the flow channel plate 10.
[0156] Specifically, the connecting sleeve 112 is fitted over the protrusion 111, and the limiting hook 1112 prevents the connecting sleeve 112 from disengaging from the protrusion 111. During assembly, the connecting sleeve 112 is inserted into the fixed bracket of the front engine compartment.
[0157] Furthermore, as can be seen from Figures 9 and 10, the connecting sleeve 112 is made of a flexible material, and the inner wall of the connecting sleeve 112 is provided with a plurality of deformable protrusions 1121, which are distributed along the circumference of the connecting sleeve 112.
[0158] Specifically, the deformable protrusion 1121 is used to absorb the manufacturing tolerances of the protrusion 111. During assembly, the outer surface of the protrusion 111 deforms the deformable protrusion 1121 by pressing it, thereby tightly fitting the connecting sleeve 112 onto the protrusion 111. If the size of the protrusion 111 is slightly smaller than the required size, the compressive force of the protrusion 111 can still ensure a tight connection between the connecting sleeve 112 and the protrusion 111. If the size of the protrusion 111 is slightly larger than the required size, the compression of the deformable protrusion 1121 increases after assembly, thereby absorbing dimensional errors.
[0159] Furthermore, as can be seen from Figure 10, the cross-section of the deformable protrusion 1121 is approximately semi-circular, and the deformable protrusion 1121 is elongated and extends along the axial direction of the connecting sleeve 112. Figure 10 also shows that multiple deformable protrusions 1121 are provided, and these multiple deformable protrusions 1121 are distributed at intervals along the circumference of the connecting sleeve 112, thereby providing a uniform compressive force to the protrusion 111 throughout the entire circumference.
[0160] As shown in Figures 9 and 10, in the technical solution of this application embodiment, a connecting hook 1122 is provided on the outer wall of the connecting sleeve 112, and a deformable recess 1123 is provided on the inner wall of the connecting sleeve 112 corresponding to the position of the connecting hook 1122.
[0161] Specifically, during assembly, the connecting hook 1122 on the connecting sleeve 112 is hooked and fixed to the fixed bracket in the front engine compartment, that is, the first side 101 of the flow channel plate 10 is fixed, so that the operator can place the flow channel plate 10 in the installation position.
[0162] Furthermore, a deformable recess 1123 is provided on the inner wall of the connecting sleeve 112 at the position corresponding to the connecting hook 1122, thereby facilitating the inward deformation of the connecting hook 1122 and reducing the assembly difficulty.
[0163] As shown in Figures 1 and 2, in the technical solution of this application embodiment, the flow channel plate 10 includes a first plate body 13 and a second plate body 14 that are interlocked with each other. A first protrusion 131 is provided on the first plate body 13, and a second protrusion 141 is provided on the second plate body 14. The first protrusion 131 and the second protrusion 141 are arranged opposite to each other and are used to cooperate with the fixture.
[0164] Specifically, the first plate 13 serves as the bottom plate of the flow channel plate 10, and the second plate 14 serves as the top plate of the flow channel plate 10; the two are interlocked and connected together. As shown in Figures 1 and 4, the aforementioned second port 302, one-way valve 80, and plug-in portion 11 are located on the first plate 13. As shown in Figures 1, 2, and 6, the various interfaces 30, heat exchanger 40, four-way valve 60, and three-way valve 70 are located on the second plate 14.
[0165] Furthermore, the ribs in the first plate 13 and the second plate 14 are correspondingly arranged, and after the two are snapped together and connected as one, the above-mentioned flow channel 20 and other cavities are formed.
[0166] The flow channel plate 10 in this embodiment is made of plastic, preferably 30% glass fiber reinforced nylon 66 (PA66-GF30). PA66-GF30 has advantages such as high strength, special thermal stability, and hydrolysis resistance, and can withstand the high temperature of engine coolant, while reducing the overall weight of the flow channel plate 10. The material of the flow channel plate 10 can also be 25% glass fiber reinforced nylon 66 (PA66-GF25) or 35% glass fiber reinforced nylon 66 (PA66-GF35), and this application is not limited to this.
[0167] In this embodiment, the first plate 13 and the second plate 14 are connected by a hot melt welding process, specifically including the following steps 1, 2 and 3.
[0168] In step 1, the first plate 13 and the second plate 14 are placed on both sides of the sheet-like heating fixture. The heating fixture is equipped with heating resistors, and the heating resistors are energized.
[0169] In step 2, the first plate 13 and the second plate 14 are clamped together by the fixture. After the heat from the heating fixture melts the mating surfaces of the first plate 13 and the second plate 14, the heating fixture is pulled out.
[0170] In step 3, the first plate 13 and the second plate 14 are continuously clamped together using a clamp. After the molten parts of the first plate 13 and the second plate 14 cool down, they are connected into a single structure, which forms the flow channel plate 10.
[0171] Furthermore, to facilitate the clamping of the first plate 13 and the second plate 14, a first protrusion 131 is provided on the first plate 13, and a second protrusion 141 is provided on the second plate 14. The first protrusion 131 and the second protrusion 141 are arranged opposite to and parallel to each other. The clamp can apply force to the first protrusion 131 and the second protrusion 141 respectively, thereby making the first plate 13 and the second plate 14 fit tightly together.
[0172] As shown in Figure 5, in the technical solution of this application embodiment, a plurality of third reinforcing ribs 15 are provided in the flow channel plate 10, and the plurality of third reinforcing ribs 15 enclose a plurality of closed regions 16. An exhaust hole 17 is provided on the flow channel plate 10, and the exhaust hole 17 is connected to at least a portion of the closed regions 16.
[0173] Specifically, the third reinforcing rib 15 mainly strengthens the overall structure of the flow channel plate 10 and supports the structure of each flow channel 20. Multiple third reinforcing ribs 15 are staggered and enclose multiple closed areas 16. In the above-mentioned hot melt welding process, the gas will expand due to heat and generate gas. Therefore, it is necessary to provide vent holes 17 in the closed areas 16 to discharge the gas in the closed areas 16.
[0174] Those skilled in the art can choose to provide vent holes 17 in all of the enclosed areas 16 or only in a portion of the enclosed areas 16, depending on actual needs.
[0175] Furthermore, in the embodiments of this application, the exhaust holes 17 are all provided on the first plate 13.
[0176] As shown in Figure 11, the heat exchanger 40 in this embodiment of the application also includes a base 41, which is used to connect the heat exchanger 40 to the flow channel plate 10. The base 41 is provided with a connection hole.
[0177] As shown in Figure 11, the thermal management integrated module also includes a fixing structure for fixing the wiring harness, which includes a wire clamp 18 and a wire support 19. The wire clamp 18 is disposed on the base 41 of the heat exchanger 40, and the wire support 19 is disposed on the flow channel plate 10, and the wire support 19 and the flow channel plate 10 are integrally formed.
[0178] Specifically, the wiring harness serves to provide power and transmit signals to the heat exchanger 40, the four-way valve 60, and the three-way valve 70. The wiring harness is fixed to the flow channel plate 10 by a fixing structure.
[0179] Furthermore, the wire clamp 18 is a standard part, with a circular piece and a barb at its lower part. During assembly, a through hole is required so that the barb can pass through and hook onto the inside of the through hole. If the wire clamp 18 is set on the flow channel plate 10, on the one hand, the through hole can easily penetrate the flow channel 20, or the flow channel 20 needs to avoid the position of the through hole, which limits the design; on the other hand, the circular piece occupies a large space and can easily encroach on the design space of other components.
[0180] Therefore, in this embodiment, the wire clamp 18 is placed at the edge of the base 41 of the heat exchanger 40, which makes use of the extra space at the edge of the base 41.
[0181] Specifically, a through hole is provided at the edge of the base 41. After the bottom of the wire clamp 18 passes through the through hole, a barb is hooked at the bottom of the through hole, and a circular piece is located outside the through hole. The circular piece and the barb fix the wire clamp 18 to the base 41. At the same time, a recess is provided on the flow channel plate 10 below the wire clamp, which provides downward assembly space for the wire clamp.
[0182] With this configuration, on the one hand, the circular plate of the wire clamp 18 utilizes the extra space of the base 41 of the heat exchanger 40 without encroaching on the space of other structures on the flow channel plate 10; on the other hand, there is no need to open through holes on the flow channel plate 10, thus not restricting the design of the flow channel 20.
[0183] As can also be seen from Figure 11, the wire support 19 has a sheet-like structure and its thickness is much smaller than that of the wire hoop 18. Therefore, the wire support 19 occupies less space and can be arranged more flexibly.
[0184] In this embodiment, a wire clamp 18 and two wire supports 19 are provided. One wire support 19 is located on the outside of the heat exchanger 40, and the other wire support 19 is located between the heat exchanger 40 and the three-way valve 70.
[0185] This application also provides a vehicle including the aforementioned thermal management integrated module.
[0186] Optionally, the vehicle is a hybrid new energy vehicle.
[0187] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and all such modifications and variations fall within the scope defined by the appended claims.
