Description

Technical Field

[0001] The present invention relates to the technical field of vehicle thermal management, and in particular to a thermal management integrated module and a vehicle. Background Art

[0002] Thermal management is an important part of vehicle driving control, which ensures that the key components of the vehicle are within a reasonable temperature range. For hybrid new energy vehicles, its thermal management also involves the heat exchange between the engine coolant and the coolant of the three-electric system (motor, battery and electronic control system). The engine and the three-electric components are scattered in the vehicle, resulting in complex water pipe connections, long pipe extension distances, and cumbersome assembly.

[0003] In order to solve this problem, some vehicles are equipped with a thermal management integrated module. The thermal management integrated module includes a flow channel plate, in which a plurality of flow channels are arranged, and the flow channel plate is provided with a plurality of interfaces connected to the flow channels. By connecting the engine coolant circuit and the three-electric system cooling circuit to the flow channel plate, the engine coolant and the three-electric system coolant can exchange heat in the water-to-water heat exchanger on the flow channel plate.

[0004] Since the temperature difference between the engine coolant and the three-electric system coolant is large, and the two are completely different media, when the engine coolant and the three-electric system coolant are close to each other at the inlet of the water-to-water heat exchanger of the flow channel plate, uncontrollable heat exchange is likely to occur before entering the water-to-water heat exchanger, resulting in a decrease in the control accuracy of thermal management. At the same time, the flow channel plate is usually two plates that are connected as a whole by welding, fasteners, etc. after being buckled together. Therefore, once the seal fails at the buckling surface, the engine coolant and the three-electric system coolant will collide. Whether the engine coolant enters the three-electric system cooling circuit, or the three-electric system coolant enters the engine cooling circuit, it will cause the vehicle to be unable to drive normally.

[0062] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0063] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, an embodiment of the thermal management integrated module according to the present application includes a flow channel plate 10 and a heat exchanger 40. The flow channel plate 10 includes a plurality of flow channels 20, and a plurality of interfaces 30 are provided on the flow channel plate 10. The plurality of flow channels 20 include a first flow channel 21 and a second flow channel 22, and the plurality of interfaces 30 include a first interface 31 and a second interface 32. The first flow channel 21 is connected to the first interface 31, and the second flow channel 22 is connected to the second interface 32. The heat exchanger 40 is provided on the flow channel plate 10, and includes a first channel and a second channel for heat exchange with each other, the first interface 31 is connected to the first channel, and the second interface 32 is connected to the second channel. Further, 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 have a gap d.

[0064] By using the technical solution of this 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 in the heat exchanger 40. At the same time, 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 have a gap d at the first interface 31 and the second interface 32, respectively, that is, the first flow channel wall 211 and the second flow channel wall 221 are isolated before entering the heat exchanger 40. The gap d allows the first interface 31 and the second interface 32 to be isolated by air, thereby reducing the uncontrollable heat exchange of the medium in the first flow channel 21 and the second flow channel 22, and even if the first flow channel 21 or the second flow channel 22 fails to seal or leaks, the coolant will flow into the gap d, and will not directly cause liquid crossflow. Therefore, the technical solution of this embodiment solves the problem of uncontrollable heat exchange and liquid crossflow in the vehicle thermal management module in the prior art.

[0065] like Figure 1 , Figure 4 and Figure 6 As shown, the flow channel plate 10 is a plate-like structure as a whole, and has a cavity inside. The cavity is formed by ribs to form a flow channel wall, and a plurality of flow channels 20 are formed in the flow channel plate 10, and the flow channels 20 are used to allow the heat exchange medium to flow through. Figure 2 It can be seen that the flow channel plate 10 is provided with a plurality of interfaces 30 , and different interfaces 30 are connected to corresponding flow channels 20 . The interfaces 30 are used to connect to external pipelines, or the interfaces 30 are used to connect to working ports of thermal management components.

[0066] Among them, thermal management parts may include: heat exchangers, reversing valves, one-way valves and various valve components, sensors, etc.

[0067] from Figure 2 and Figure 6 It can be seen that 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. Figure 1 Therefore, 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 realizing heat exchange between the first heat exchange medium and the second heat exchange medium in the heat exchanger 40.

[0068] 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 may be the same medium or different mediums.

[0069] Specifically in this embodiment, the first heat exchange medium in the first flow channel 21 is engine coolant, and the second heat exchange medium in the second flow channel 22 is three-electric system coolant. That is, the first heat exchange medium and the second heat exchange medium are different media.

[0070] Optionally, the heat exchanger 40 in this embodiment is a water-to-water heat exchanger.

[0071] like Figure 1 and Figure 2 As shown, since the overall volume of the heat exchanger 40 is small, the positions of the working ports of the heat exchanger 40 are arranged close to each other, so the positions of the first interface 31 and the second interface 32 are also arranged close to each other. The temperature difference between the first heat exchange medium and the second heat exchange medium before passing through the heat exchanger 40 for heat exchange is large, so it is easy for the two to easily undergo uncontrollable heat exchange at the first interface 31 and the second interface 32 before entering the heat exchanger 40, resulting in reduced control accuracy of thermal management.

[0072] For this reason, Figure 6 and Figure 7 As shown, a portion of the first channel wall 211 of the first channel 21 at the first interface 31 and a portion of the second channel wall 221 of the second channel 22 at the second interface 32 have a gap d. Therefore, the first interface 31 and the second interface 32 are isolated by the air in the gap d, which greatly slows down the heat conduction between the first heat exchange medium and the second heat exchange medium, that is, it eliminates the situation where the first heat exchange medium and the second heat exchange medium have uncontrollable heat exchange before entering the heat exchanger 40.

[0073] Furthermore, when the first heat exchange medium and the second heat exchange medium are different media, when the sealing of the first flow channel wall 211 fails, the first heat exchange medium will leak into the gap d, and will not directly flow into the second flow channel wall 221. Correspondingly, when the sealing of the second flow channel wall 221 fails, the second heat exchange medium will leak into the gap d, and will not directly flow into the first flow channel wall 211. That is, the above-mentioned gap d can also prevent the first heat exchange medium and the second heat exchange medium from liquid crosstalk.

[0074] like Figure 7 and Fig.12 As shown, in the technical solution of this embodiment, the first interface 31 is located at the end of the first flow channel 21, 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.

[0075] Specifically, by spacing the end of the first channel 21 from the second channel wall 221 , the first interface 31 and the second channel 22 as a whole have a certain gap, thereby further reducing the uncontrollable heat exchange between the first heat exchange medium and the second heat exchange medium.

[0076] Correspondingly, by spacing the end of the second channel 22 from the first channel wall 211, a certain gap is provided between the second interface 32 and the first channel 21 as a whole, which further reduces the uncontrollable heat exchange between the first heat exchange medium and the second heat exchange medium.

[0077] like Figure 7 As shown, since the first channel wall 211 and the second channel wall 221 are arranged at intervals, a first reinforcing rib 50 is connected between the first channel wall 211 and the second channel wall 221 to enhance the structural strength of the first channel wall 211 and the second channel wall 221 .

[0078] like Figure 2 , Figure 4 , Figure 6 and Fig.12 As shown, in the technical solution of this embodiment, there are two first flow channels 21, and the two first interfaces 31 are respectively connected to the two first flow channels 21. The multiple interfaces 30 also include two third interfaces 33, and the two third interfaces 33 are respectively connected to the two first flow channels 21, and the two third interfaces 33 are used to communicate with the engine cooling circuit.

[0079] And from 4 and Figure 6 It can be seen that, for a first flow channel 21 , the first interface 31 and the third interface 33 are located at two ends of the first flow channel 21 , respectively.

[0080] Specifically, the first flow channel 21 is used to pass high-temperature engine coolant. Among the two third interfaces 33, one is the engine coolant inlet and the other is the 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 after heat exchange flows out through the other first flow channel 21.

[0081] 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 interfaces 31. After heat exchange in the heat exchanger 40, the engine coolant flows into another first flow channel 21 through another first interface 31.

[0082] like Figure 1 , Figure 2 , Figure 4 , Figure 6 and Fig.12As shown, in the technical solution of this embodiment, there are two second flow channels 22. The plurality of interfaces 30 further include two fourth interfaces 34 and two fifth interfaces 35, and the plurality of flow channels 20 further include 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.

[0083] Furthermore, a four-way valve 60 is also provided on the flow channel plate 10, and the two fourth interfaces 34 and the two fifth interfaces 35 are both connected to the four-way valve 60, wherein the third flow channel 23 and the fourth flow channel 24 are used to communicate with one or more of the following cooling circuits:

[0084] Motor cooling circuit, battery cooling circuit and electronic control system cooling circuit.

[0085] Specifically, one of the two second flow channels 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 to flow out of the heat exchanger 40 after heat exchange, that is, the second heat exchange medium exchanges heat with the first heat exchange medium in the heat exchanger 40. Fig.12 It can be seen that the second interface 32 and the fourth interface 34 are respectively located at two ends of the second flow channel 22 .

[0086] Furthermore, the second heat exchange medium is introduced into the third flow channel 23 and the fourth flow channel 24, and the third flow channel 23 is an outflow flow channel, and the fourth flow channel 24 is an inflow flow channel. In this embodiment, the third flow channel 23 and the fourth flow channel 24 are connected to the three-electric cooling circuit, that is, the third flow channel 23 and the fourth flow channel 24 flow the three-electric system coolant.

[0087] It should be noted that the "three electrics" refer to electric motors, batteries and electronic control systems.

[0088] In some embodiments, the third flow channel 23 and the fourth flow channel 24 may also be connected only to the motor cooling circuit, or only to the battery cooling circuit, or only to the electronic control system cooling circuit.

[0089] 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, may also be connected to the battery cooling circuit and the electronic control system cooling circuit, or may also be connected to the motor cooling circuit and the electronic control system cooling circuit.

[0090] In some embodiments, the third flow channel 23 and the fourth flow channel 24 may be in communication with a motor cooling circuit, a battery cooling circuit, and an electronic control system cooling circuit.

[0091] like Fig.12 As shown, the two fifth interfaces 35 are respectively located at the end positions of the third flow channel 23 and the fourth flow channel 24 .

[0092] from Fig.12 It can also be seen that the two fourth interfaces 34 and the two fifth interfaces 35 are arranged in a cross shape, and when the four-way valve 60 is installed on the flow channel plate 10, the two fourth interfaces 34 and the two fifth interfaces 35 are respectively connected to the four working ports of the four-way valve 60. Therefore, the four-way valve 60 can have a reversing effect on the coolant of the three-electric system.

[0093] In this embodiment, the four-way valve 60 is used to control whether the three-electric system coolant exchanges heat with the engine coolant. Specifically:

[0094] When heat exchange is required, the four-way valve 60 controls one of the fifth interfaces 35 to communicate with one of the fourth interfaces 34, and another fifth interface 35 to communicate with another fourth interface 34. At this time, the three-electric system coolant flows into the heat exchanger 40 through the fourth flow channel 24 and one of the second flow channels 22. After heat exchange, the three-electric system coolant 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.

[0095] When heat exchange is not required, the four-way valve 60 controls the two fifth interfaces 35 to be connected and the two fourth interfaces 34 to be connected. At this time, the coolant of the three-electric system is directly discharged from the channel plate 10 through the fourth channel 24 and the third channel 23, that is, heat exchange is not performed in the heat exchanger 40.

[0096] like Figure 2 , Figure 4 , Figure 6 and Fig.12 As shown, in the technical solution of this embodiment, the plurality of interfaces 30 further include a sixth interface 36 , which is in communication with the third flow channel 23 , and is used to discharge the heat exchange medium from the flow channel plate 10 .

[0097] from Fig.12 It can be seen that one of the fifth interface 35 and the sixth interface 36 is located at the two ends of the third flow channel 23. The sixth interface 36 is used for external piping, so that the three-electric system coolant after or without heat exchange flows back to the three-electric system cooling circuit.

[0098] like Figure 1 , Figure 2 , Figure 4 , Figure 6 and Fig.12As shown, in the technical solution of this embodiment, the plurality of flow channels 20 further include a fifth flow channel 25 and a sixth flow channel 26, and the plurality of 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 in communication with the fourth flow channel 24, the eighth interface 38 and the ninth interface 39 are both in communication with the fifth flow channel 25, the tenth interface 310 and the eleventh interface 311 are both in communication with the sixth flow channel 26, and a three-way valve 70 is further provided on the flow channel plate 10, the seventh interface 37, the eighth interface 38, and the tenth interface 310 are all in communication with the three-way valve 70, and 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.

[0099] Specifically, the fifth flow channel 25 and the sixth flow channel 26 in this embodiment are used to allow the three-electric system coolant to enter the flow channel plate 10. Fig.12 It can be seen that the eighth interface 38 and the ninth interface 39 are respectively located at two ends of the fifth flow channel 25, and the tenth interface 310 and the eleventh interface 311 are respectively located at two ends of the sixth flow channel 26. Among them, the ninth interface 39 and the eleventh interface 311 are inlets.

[0100] from Fig.12 It can also be seen that the eighth interface 38, the seventh interface 37 and the tenth interface 310 are arranged in a straight line, and the seventh interface 37 is located between the eighth interface 38 and the tenth interface 310. When the three-way valve 70 is installed on the flow channel plate 10, the eighth interface 38, the seventh interface 37 and the tenth interface 310 are connected to the three working ports of the three-way valve 70.

[0101] In this embodiment, the function of the three-way valve 70 is to make the three-electric system coolant in the fifth flow channel 25 and the three-electric system coolant in the sixth flow channel 26 selectively communicate with the fourth flow channel 24. Specifically:

[0102] When the three-way valve 70 is switched to connect the eighth interface 38 with the seventh interface 37 , the fifth channel 25 is connected with the fourth channel 24 , and the three-electric system coolant in the fifth channel 25 can pass through the fourth channel 24 and the second channel 22 and enter the heat exchanger 40 for heat exchange.

[0103] When the three-way valve 70 is switched to connect the tenth interface 310 with the seventh interface 37 , the sixth channel 26 is connected with the fourth channel 24 , and the three-electric system coolant in the sixth channel 26 can pass through the fourth channel 24 and the second channel 22 and enter the heat exchanger 40 for heat exchange.

[0104] like Figure 1 , Figure 2 , Figure 4 , Figure 6 and Fig.12As shown, in the technical solution of this embodiment, a one-way valve 80 is arranged on the flow channel plate 10, the multiple interfaces 30 also include a twelfth interface 312, 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, wherein the one-way valve 80 is used to allow the heat exchange medium to flow in one direction from the eleventh interface 311 to the twelfth interface 312.

[0105] Specifically, the function of the seventh flow channel 27 is to partially divert the three-electric system coolant entering from the eleventh interface 311. A portion of the three-electric system coolant entering from the eleventh interface 311 flows into the sixth flow channel 26, and the other portion flows into the seventh flow channel 27 after passing through the one-way valve 80, and finally is discharged from the flow channel plate 10 through the twelfth interface 312.

[0106] like Fig.13 As shown, in the technical solution of this 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 communicate with the engine cooling circuit, and the low-temperature flow channel 202 is used to communicate with one or more of the following cooling circuits: a motor cooling circuit, a battery cooling circuit, and an electronic control system cooling circuit.

[0107] The high-temperature flow channel 201 and the low-temperature flow channel 202 are separated by a heat exchanger 40 .

[0108] Specifically, the engine coolant (about 100°C) with a relatively high temperature flows in the high temperature flow channel 201 of this embodiment, and the three-electric system coolant with a relatively low temperature flows in the low temperature flow channel 202. If the two coolants exchange heat at a position other than the heat exchanger 40, uncontrollable heat exchange will occur, which will affect the control accuracy of thermal management and should be reduced or eliminated as much as possible.

[0109] from Fig.13 It can be seen that the dotted area where the high-temperature flow channel 201 is located and the dotted area where the low-temperature flow channel 202 is located are separated by the heat exchanger 40, so 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, alleviating the uncontrollable heat exchange situation.

[0110] In this embodiment, the high-temperature flow channel 201 includes two first flow channels 21 .

[0111] In this embodiment, 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 .

[0112] like Fig.14As shown, in the technical solution of this 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. The plurality of flow channels 20 include a first staggered flow channel 203 and a second staggered flow channel 204, the first staggered flow channel 203 extends in the preset plane, and the second staggered flow channel 204 includes a staggered portion 2041, and the projection of the staggered portion 2041 on the preset plane at least partially overlaps with the first staggered flow channel 203. And the extension direction of the staggered portion 2041 has a first preset angle a with the preset plane.

[0113] First, it should be noted that the flow channel plate 10 includes a first plate body 13 and a second plate body 14, which are interlocked to form the flow channel plate 10. Figure 2 The above-mentioned preset plane refers to the plane where the buckling surfaces of the first plate body 13 and the second plate body 14 are located, and the first direction and the second direction are two perpendicular directions on the buckling surfaces. 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.

[0114] Of course, those skilled in the art may also change the specific positions represented by the first direction, the second direction and the third direction according to actual needs.

[0115] Furthermore, the plurality of flow channels 20 include a first staggered flow channel 203 and a second staggered flow channel 204, wherein the "staggered flow channel" means that the projections of the two on the preset plane have an overlapping portion, and refer to Fig.15 The dashed shaded box in FIG.

[0116] Further, the second staggered flow channel 204 includes a staggered portion 2041 , and the staggered portion 2041 means that the second staggered flow channel 204 is staggered with the first staggered flow channel 203 in this portion, and the rest of the portion is not staggered.

[0117] In this embodiment, the staggered portion 2041 and the first staggered flow channel 203 form a 90° intersection, which means that after the staggered portion 2041 and the first staggered flow channel 203 are projected onto the above-mentioned preset plane, the projection of the staggered portion 2041 and the projection of the first staggered flow channel 203 are arranged at 90°. Fig.14 It can be seen that the extension direction of the staggered portion 2041 has a first preset angle a with the above-mentioned preset plane, that is, the staggered portion 2041 is inclined relative to the flow channel plate 10 .

[0118] In the prior art, for the flow channel plate of the thermal management integrated module, its interface is usually set to be perpendicular to each other, including horizontal and vertical directions. Such a design is conducive to demolding after casting. If the flow channels are staggered during design, the following two methods are usually used to solve it:

[0119] 1. The flow channel plate is designed as a double-layer structure, with two staggered flow channels, one of which is located on the upper layer and the other on the lower layer;

[0120] 2. Modify the location of the entrance or exit, cancel the staggered part (that is, cancel Fig.15 The interlaced portion 2041 in the figure).

[0121] However, in the traditional design methods, the first one will increase the thickness of the flow channel plate, increasing the cost and the space occupied in the car, and the second one will limit the position of the interface and greatly reduce the design flexibility.

[0122] To this end, in this embodiment, the staggered portion 2041 is configured such that its extension direction has a first preset angle a with the preset plane. That is, the staggered portion 2041 is configured in an oblique manner. Such a configuration has the following two advantages:

[0123] 1. When the flow channel plate 10 has only one layer, the first staggered flow channel 203 and the second staggered flow channel 204 can also have staggered parts, and the flow channel plate 10 does not need to be designed as two layers;

[0124] 2. By rotating the staggered portion 2041 with the third direction as the rotation axis, the orientation of the staggered portion 2041 can be changed, which is beneficial for flexible arrangement of the position of the interface 30 compared to the vertically arranged interface 30.

[0125] from Fig.14 It can be seen that in this embodiment, the first staggered flow channel 203 is the seventh flow channel 27, and the second staggered flow channel 204 is the fifth flow channel 25. Figure 2 It can be seen that the end of the staggered portion 2041 forms the ninth interface 39, that is, the ninth interface 39 is in an oblique insertion form.

[0126] In some embodiments not shown, the first staggered flow channel 203 and the second staggered flow channel 204 may be any two of the above-mentioned flow channels 20 , and the ends of the staggered portions 2041 may also form any of the above-mentioned interfaces 30 .

[0127] Optionally, the first preset angle a is in the range of 30° to 60°.

[0128] For example, the first preset angle a may be 30°, 40°, 45°, 50°, 55° or 60°, etc., and any value between the two values.

[0129] Preferably, the first preset angle a is 45°.

[0130] like Figure 6 , Figure 8 as well as Fig.12 As shown, in the technical solution of this embodiment, the inner wall of the first staggered flow channel 203 is provided with a second reinforcing rib 2031 at a position overlapping with the staggered portion 2041 .

[0131] Specifically, the inner wall of the overlapping position of the first staggered flow channel 203 and the staggered portion 2041 will be thinned. In order to ensure the strength of the flow channel wall at the overlapping position, a second reinforcing rib 2031 is provided at this position.

[0132] like Figures 1 to 3 ,as well as Fig.16 As shown, in the technical solution of this embodiment, the flow channel plate 10 is provided with a first opening 301 and a second opening 302. The first opening 301 and the second opening 302 are both connected to the first staggered flow channel 203, and the first opening 301 and the second opening 302 are staggered in the third direction, wherein the extension direction of the first staggered flow channel 203 has a second preset angle b with the preset plane, and along the third direction, two opposite inner walls of the first staggered flow channel 203 are arranged in parallel.

[0133] Specifically, from Fig.16 It can be seen that the first opening 301 and the second opening 302 are respectively located on both sides of the staggered portion 2041. In the third direction, the first opening 301 and the second opening 302 are staggered, and the second opening 302 is located below the first opening 301, so the overall extension direction of the first staggered flow channel 203 is inclined.

[0134] Since the staggered portion 2041 is in the form of an oblique insertion, the thickness of the flow channel plate 10 and each flow channel 20 is slightly increased. Fig.17 The content, along Fig.17 In the direction shown in FIG. 1 , the upper wall surface of the first staggered flow channel 203 extends obliquely, and the lower wall surface of the first staggered flow channel 203 extends in an "L" shape. This will cause a sudden change in the flow area of ​​the first staggered flow channel 203, which is not conducive to the flow stability of the heat exchange medium.

[0135] Therefore, in this embodiment, along the third direction, the two opposite inner walls of the first staggered flow channel 203 are arranged in parallel, that is, the first staggered flow channel 203 is arranged in parallel. Fig.16 The upper wall and the lower wall are arranged in parallel. This ensures that the flow area in the first staggered flow channel 203 remains consistent, which is beneficial to the flow stability of the heat exchange medium.

[0136] from Figure 1, Figure 2 and Fig.16 It can be seen that the first port 301 is also the aforementioned twelfth port 312 , and the second port 302 is used to install the aforementioned one-way valve 80 .

[0137] In some embodiments not shown, the first through opening 301 and the second through opening 302 may form any of the above-mentioned interfaces 30 , or form a through opening structure for mounting other components.

[0138] like Fig.14 As shown, in the technical solution of this embodiment, the flow channel plate 10 has a first direction, a second direction and a third direction that are perpendicular to each other, the first direction and the second direction form a preset plane, at least part of the flow channel 20 extends in the preset plane, and the extension direction of at least part of the interface 30 has a third preset angle c with the preset plane.

[0139] Specifically, as shown above, when the interface 30 is in an oblique insertion form, the interface 30 rotates with the third direction as the rotation axis, which can change the direction of the interface 30, which is conducive to the flexible arrangement of the position of the interface 30 compared to the vertically arranged interface 30. Therefore, in this embodiment, even if the flow channel 20 does not form a staggered form, its interface 30 can also be set in an inclined form.

[0140] Optionally, the third preset angle c is the same as the first preset angle a mentioned above.

[0141] Optionally, the third preset angle c is in the range of 30° to 60°.

[0142] For example, the third preset angle c may be 30°, 40°, 45°, 50°, 55° or 60°, etc., and any value between the two values.

[0143] Preferably, the third preset angle c is 45°.

[0144] from Fig.12 and Fig.14 It can be seen that in this embodiment, the sixth flow channel 26 is also formed in 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.

[0145] Of course, in some embodiments not shown, in any of the above-mentioned flow channels 20, the interface 30 thereof can be configured to have an extension direction that has a third preset angle c with the preset plane.

[0146] like Figure 4 As shown, in the technical solution of this embodiment, among the multiple flow channels 20 , the bottom walls of at least some of the flow channels 20 are provided with a guide slope 205 , and the guide slope 205 is located at the end of the flow channel 20 .

[0147] Specifically, the main direction in which the heat exchange medium flows into or out of the flow channel plate 10 is along the third direction (refer to Fig.12 , except for the ninth interface 39, the eleventh interface 311 and the twelfth interface 312), and each flow channel 20 extends along the above-mentioned preset plane. This situation will cause the heat exchange medium to pass through the right-angle corner when flowing into or out of the flow channel plate 10, which will increase the flow resistance of the heat exchange medium and increase energy consumption.

[0148] In this embodiment, a guide slope 205 is provided at the end of the bottom wall of the flow channel 20 , 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.

[0149] Those skilled in the art may choose according to actual needs, and may set the guide slope 205 in all the flow channels 20 , or only set the guide slope 205 in part of the flow channels 20 .

[0150] Those skilled in the art may choose to provide the guide slope 205 only at one end of the flow channel 20 , or provide the guide slope 205 at both ends of the flow channel 20 , according to actual needs.

[0151] like Figure 4 As shown, in the technical solution of this embodiment, among the multiple flow channels 20, at least some of the flow channels 20 are provided with diverter ribs 206, and the diverter ribs 206 are located at the bends, and / or diameter changes, and / or ends of the flow channels 20.

[0152] Specifically, the flow dividing ribs 206 can guide and divide the heat exchange medium. Those skilled in the art can adaptively select the position and shape of the flow dividing ribs 206 in the flow channel 20 according to the simulation results of the flow medium.

[0153] When the flow dividing ribs 206 are disposed at the bend of the flow channel 20 , it is possible to prevent the heat exchange media on both sides from influencing each other, so that the heat exchange media can pass through the bend more smoothly.

[0154] When the flow-dividing ribs 206 are disposed at the diameter-changing portion of the flow channel 20 , they can divert the heat exchange medium and reduce the flow resistance of the heat exchange medium.

[0155] When the flow dividing rib 206 is disposed at the end of the flow channel 20 , the flow resistance of the heat exchange medium flowing in or out can be reduced.

[0156] Those skilled in the art may choose according to actual needs, and may set the flow-dividing ribs 206 in all the flow channels 20 , or only set the flow-dividing ribs 206 in part of the flow channels 20 .

[0157] like Figure 1 and Figure 2 As shown, in the technical solution of this embodiment, the flow channel plate 10 has an opposite 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, and the connecting hole 12 is used for fasteners to pass through.

[0158] Specifically, the thermal management integrated module in this embodiment is installed in a vertical manner in the front engine compartment of the vehicle when installed in the vehicle. That is, after the flow channel plate 10 is installed, its first side 101 faces the upper side (or obliquely upward) of the vehicle, and its second side 102 faces the lower side (or obliquely downward) of the vehicle.

[0159] During assembly, the operator first inserts the plug-in portion 11 of the flow channel plate 10 into the fixing bracket of the front engine compartment, then places the flow channel plate 10 at the installation position, and finally passes the fastener through the connecting hole 12 and tightens it in the front engine compartment.

[0160] from Figure 1 and Figure 2 It can be seen that 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, and the central hole portion of the annular sleeve forms the above-mentioned connecting hole 12 .

[0161] like Fig. 9 and Fig.10 As shown, in the technical solution of this embodiment, the plug-in portion 11 includes a protrusion 111 connected to the flow channel plate 10, and a connecting sleeve 112 sleeved outside the protrusion 111, and a limiting hook 1112 is provided on the protrusion 111, and the limiting hook 1112 cooperates with the surface of the connecting sleeve 112 facing away from the flow channel plate 10.

[0162] Specifically, the connecting sleeve 112 is sleeved outside the protrusion 111, and the limiting hook 1112 prevents the connecting sleeve 112 from being separated from the protrusion 111. During assembly, the connecting sleeve 112 is plugged and matched with the fixing bracket of the front cabin.

[0163] Further, from Fig. 9 and Fig.10 It can be seen that 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 , and the plurality of deformable protrusions 1121 are distributed along the circumference of the connecting sleeve 112 .

[0164] Specifically, the deformed protrusion 1121 is used to absorb the manufacturing tolerance of the protrusion 111. During assembly, the outer surface of the protrusion 111 squeezes the deformed protrusion 1121 to deform, so that the connecting sleeve 112 is tightly sleeved outside the protrusion 111. If the size of the protrusion 111 is slightly smaller than the required size, the squeezing force of the protrusion 111 can also ensure the 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 amount of the deformed protrusion 1121 increases after assembly, thereby absorbing the size error.

[0165] Further, from Fig.10 It can be seen that the cross section of the deformed protrusion 1121 is approximately semicircular, and the deformed protrusion 1121 is in the shape of an elongated strip and extends along the axial direction of the connecting sleeve 112. Fig.10 It can also be seen that a plurality of deformed protrusions 1121 are provided, and the plurality of deformed protrusions 1121 are distributed at intervals along the circumference of the connecting sleeve 112 , thereby providing a uniform squeezing force on the protrusion 111 in the entire circumference.

[0166] like Fig. 9 and Fig.10 As shown, in the technical solution of this embodiment, a connecting hook 1122 is provided on the outer wall of the connecting sleeve 112 , and a deformed recess 1123 is provided on the inner wall of the connecting sleeve 112 at a position corresponding to the connecting hook 1122 .

[0167] Specifically, during assembly, the connecting hook 1122 on the connecting sleeve 112 is hooked and fixed to the fixing bracket of the front cabin, that is, the first side 101 of the flow channel plate 10 is fixed, so that it is convenient for the operator to place the flow channel plate 10 at the installation position.

[0168] Furthermore, a deformation recess 1123 is provided on the inner wall of the connecting sleeve 112 at a position corresponding to the connecting hook 1122 , thereby facilitating the inward deformation of the connecting hook 1122 and reducing the difficulty of assembly.

[0169] like Figure 1 and Figure 2 As shown, in the technical solution of this embodiment, the flow channel plate 10 includes a first plate body 13 and a second plate body 14 that are interlocked. The first plate body 13 is provided with a first convex strip 131, and the second plate body 14 is provided with a second convex strip 141. The first convex strip 131 and the second convex strip 141 are arranged opposite to each other and are used to cooperate with the clamp.

[0170] Specifically, the first plate 13 is used as the bottom plate of the flow channel plate 10, and the second plate 14 is used as the top plate of the flow channel plate 10, and the two are buckled and connected together. Figure 1 and Figure 4 It can be seen that the second port 302, the one-way valve 80 and the plug-in portion 11 are arranged on the first plate body 13. Figure 1 , Figure 2 and Figure 6 It can be seen that the interfaces 30 , the heat exchanger 40 , the four-way valve 60 and the three-way valve 70 are arranged on the second plate body 14 .

[0171] Furthermore, the ribs in the first plate body 13 and the second plate body 14 are arranged correspondingly, and after the two are buckled and connected as a whole, the above-mentioned flow channel 20 and other cavities are formed.

[0172] The material of the flow channel plate 10 in this embodiment is plastic, and preferably PA66-GF30. PA66-GF30 has the advantages of high strength, special thermal stability, hydrolysis resistance, etc., can withstand the high temperature of the engine coolant, and reduce the overall weight of the flow channel plate 10.

[0173] In this embodiment, the first plate body 13 and the second plate body 14 are welded by hot melt welding, and the specific process includes:

[0174] 1. Place the first plate 13 and the second plate 14 on both sides of a sheet-shaped heating tool, on which a heating resistor is provided, and energize the heating resistor;

[0175] 2. Clamp the first plate 13 and the second plate 14 by a fixture, and after the heat of the heating tool melts the fastening surfaces of the first plate 13 and the second plate 14, remove the heating tool;

[0176] 3. The fixture continuously clamps the first plate body 13 and the second plate body 14 . After the molten parts of the first plate body 13 and the second plate body 14 are cooled, the two are connected into an integral structure, that is, the flow channel plate 10 is formed.

[0177] Furthermore, in order to facilitate the clamp to fix the first plate 13 and the second plate 14, a first convex strip 131 is provided on the first plate 13, and a second convex strip 141 is provided on the second plate 14. The first convex strip 131 and the second convex strip 141 are arranged opposite and parallel to each other. The clamp can apply force to the first convex strip 131 and the second convex strip 141 respectively, so that the first plate 13 and the second plate 14 are closely attached together.

[0178] like Figure 5 As shown, in the technical solution of this 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 areas 16. The flow channel plate 10 is provided with exhaust holes 17, and the exhaust holes 17 are connected to at least part of the closed areas 16.

[0179] Specifically, the third reinforcing ribs 15 mainly play the role of reinforcing the overall structure of the flow channel plate 10 and supporting and reinforcing the structure of each flow channel 20. A plurality of third reinforcing ribs 15 are staggered and enclosed to form a plurality of closed areas 16. In the above-mentioned hot melt welding process, the gas will expand due to heat and generate gas, so it is necessary to set a vent hole 17 in the closed area 16 to discharge the gas in the closed area 16.

[0180] Those skilled in the art may choose to provide the exhaust holes 17 in all the enclosed areas 16 or only in part of the enclosed areas 16 according to actual needs.

[0181] Furthermore, the exhaust holes 17 of this embodiment are all arranged on the first plate body 13 .

[0182] like Fig.11 As shown, the heat exchanger 40 of this embodiment further includes a base 41 , which is used to connect the heat exchanger 40 to the flow channel plate 10 , and a connecting hole is provided on the base 41 .

[0183] like Fig.11 As shown, the thermal management integrated module also includes a fixing structure for fixing the wire harness, and the fixing structure includes a wire hoop 18 and a wire support 19. The wire hoop 18 is arranged on the base 41 of the heat exchanger 40, and the wire support 19 is arranged on the flow channel plate 10, and the wire support 19 and the flow channel plate 10 are integrally formed.

[0184] Specifically, the wire harness serves to supply power and transmit signals to the heat exchanger 40, the four-way valve 60 and the three-way valve 70. The wire harness is fixed to the flow channel plate 10 by a fixing structure.

[0185] Furthermore, the wire hoop 18 is a standard part, and a circular piece and a barb are provided at the bottom thereof. During assembly, a through hole needs to be provided to allow the barb to pass through, and the barb is hooked on the inner side of the through hole. If the wire hoop 18 is provided on the flow channel plate 10, on the one hand, the through hole is easy to 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, which is easy to encroach on the design space of other components.

[0186] Therefore, in this embodiment, the wire clamp 18 is arranged at the edge of the base 41 of the heat exchanger 40, that is, the extra space at the edge of the base 41 is utilized.

[0187] Specifically, a through hole is provided at the edge of the base 41. After the bottom of the wire hoop 18 passes through the through hole, a barb is provided at the bottom of the through hole, and a circular sheet is located outside the through hole. The circular sheet and the barb fix the wire hoop 18 on the base 41. At the same time, a recess is provided below the flow channel plate 10 corresponding to the wire hoop, and the recess is used to provide a downward assembly space for the wire hoop.

[0188] With such arrangement, on the one hand, the circular piece 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, it is not necessary to open flow holes on the flow channel plate 10, and no restrictions are imposed on the design of the flow channel 20.

[0189] from Fig.11 It can also be seen that the wire support 19 is a sheet-like structure, and its thickness is much smaller than the wire hoop 18, so the arrangement of the wire support 19 is more flexible and occupies less space.

[0190] In this embodiment, one wire clamp 18 and two wire holders 19 are provided. One wire holder 19 is located outside the heat exchanger 40, and the other wire holder 19 is located between the heat exchanger 40 and the three-way valve 70.

[0191] The present application also provides a vehicle. According to an embodiment of the vehicle of the present application, the vehicle includes the above-mentioned thermal management integrated module.

[0192] Optionally, the vehicle is a hybrid new energy vehicle.

[0193] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
