[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit its scope.

[0020] The integrated device of this application is used in thermal management systems, particularly vehicle thermal management systems, and can also be used in commercial, residential, and energy storage thermal management systems.

[0021] like Figures 1-10 As shown, this application provides a thermal management component 100, including a flow channel plate 1, a controller 2, a functional component 3, a wiring harness 4, and a fixing component 5. The controller 2, the functional component 3, and the wiring harness 4 are all integrated on the flow channel plate 1. The functional component 3 is fixedly connected to the flow channel plate 1 or limitedly connected, for example, by welding, bonding, fasteners, or snap-fit. In this application, the functional component 3 is connected to the flow channel plate 1 in multiple ways. One part is fixed by threaded connection, which is convenient for installation and disassembly and subsequent maintenance. Another part is fixed by welding, which helps to ensure sealing and further prevent leakage. Functional component 3 is at least one of valve component 31, pump component 32, sensor component 33, and heat exchanger 34. In this application, functional component 3 includes valve component 31, pump component 32, sensor component 33, and heat exchanger 34. Valve component 31, pump component 32, sensor component 33, and heat exchanger 34 are fixedly connected or limited to flow channel plate 1. Valve component 31, pump component 32, sensor component 33, and heat exchanger 34 are located on the same plane of flow channel plate 1, making the structure of thermal management component 100 more compact. Of course, in other specific embodiments, they can also be located on different faces of flow channel plate 1. Controller 2 is fixedly connected or limited to flow channel plate 1, for example, by welding, bonding, fasteners, or snap-fit. In this application, controller 2 is fixed to flow channel plate 1 by threaded connection. Threaded connection facilitates maintenance and replacement, and during assembly, it is easy to adjust the position and preload of parts. In addition, compared with non-removable connections such as welding and riveting, threaded connection has lower cost and can be reused, further reducing maintenance costs.

[0022] The function of the fixing component 5 is to secure the wiring harness 4, preventing it from moving. This prevents instability in the connection between the wiring harness 4 and the controller 2 or functional component 3 during system operation, thus ensuring the normal operation of the thermal management system. The fixing component 5 has a snap-fit ​​structure; one end of the fixing component 5 is fitted onto the outer wall of the wiring harness 4, and the other end is snapped into the flow channel plate 1. This snap-fit ​​structure saves cost and assembly time, and is also detachable for easy maintenance. One end of the wiring harness 4 connects to the controller 2, and the other end connects to the functional component 3. The number of fixing components 5 is unlimited; multiple fixing components can be used. The controller 2 communicates with the functional component 3 through the wiring harness 4 to control its operation. The flow channel plate 1 has a flow channel 104, which is connected to the functional component 3. Specifically, the interfaces of the valve component 31, pump component 32, heat exchanger 34, and sensor component 33 are connected to the flow channel, allowing control of different fluid flow patterns or detection of parameters such as temperature and pressure within the flow channel. Multiple components are integrated onto the flow channel plate 1, increasing its integration and making the thermal management assembly 100 more compact. If the controller 2 is too far from the functional component 3, resulting in an excessively long wiring harness 4, it will significantly reduce the product's electromagnetic compatibility (EMC) performance and weaken its electromagnetic interference immunity (EMS). However, in this application, both the controller 2 and the functional component 3 are mounted on the flow channel plate 1. Compared to mounting the controller 2 in other locations on the vehicle body, the distance between the controller 2 and the functional component 3 is relatively shorter, effectively reducing the length of the wiring harness 4 used to connect them. This enhances the EMC performance of the thermal management assembly 100 and also reduces costs to some extent. Furthermore, since both the controller 2 and the functional component 3 are mounted on the flow channel plate 1, the connector of the wiring harness 4 is directly assembled with the controller 2 and the functional component 3 during assembly. Additionally, during the transportation of the thermal management assembly 100, there is no need for separate protection of the connector of the wiring harness 4, further reducing production costs.

[0023] like Figures 1-8As shown, the flow channel plate 1 includes a main body 11 and a cantilever 12. In this application, the main body 11 and the cantilever 12 are an integral structure, that is, the main body 11 and the cantilever 12 are integrally injection molded. The integral injection molding has no seams or connection points, which is beneficial to strengthening the strength of the flow channel plate 1 and improving the overall durability of the flow channel plate 1. Of course, in other specific embodiments, the main body 11 and the cantilever 12 can also be separate structures. The main body 11 and the cantilever 12 are fixedly connected or limited connected, such as by welding, bonding, fasteners, and snap-fit ​​limiting. If the separate structure is a detachable connection method, it is beneficial to improve the utilization rate of parts, facilitate the later upgrading and replacement of parts, and further facilitate the later maintenance. At the same time, disassembling the parts is also beneficial to reduce the processing difficulty of individual parts, and further reduce the processing cost to a certain extent. The cantilever portion 12 is located on the side of the main body portion 11 and extends outward relative to the main body portion 11. The extension direction of the cantilever portion 12 intersects the thickness direction of the main body portion 11, indicating that there is a certain angle between the cantilever portion 12 and the main body portion 11. In this application, the thickness direction of the main body portion 11 is consistent with the thickness direction of the flow channel plate 1. The controller 2 is fixedly connected to the cantilever portion 12 or is limitedly connected, for example, by welding, bonding, fasteners, or snap-fit ​​limiting. In this application, the controller 2 is fixed to the cantilever portion 12 by a threaded connection. The threaded connection facilitates maintenance and replacement, and also facilitates adjustment of the position and preload of parts during assembly. Threaded connections are low in cost and can be reused, further reducing maintenance costs.

[0024] Functional components 3 are fixedly connected to or limited by the main body 11, for example, by welding, bonding, fasteners, or snap-fit. In this application, some functional components 3 are threadedly connected to the main body 11, which facilitates disassembly and installation and subsequent maintenance. Some are fixedly connected by welding, which helps to ensure sealing and prevent leakage. In this application, the main body 11 has a flow channel 104, while the cantilever 12 does not have a flow channel 104. Therefore, the valve component 31, pump component 32, sensor component 33, and heat exchanger 34 are all concentrated on the main body 11, and the functional components 3 communicate with the flow channel 104. The flow channel plate 1 has a flow cavity 101, which is an open structure at both ends. The controller 2 includes a heat dissipation part 21, at least a portion of which is disposed opposite to the flow cavity 101, or at least a portion of which is located within the flow cavity 101. At least a portion of the heat dissipation section 21 is disposed opposite to the flow cavity 101, that is, assuming there is a central plane between the heat dissipation section 21 and the flow cavity 101, and the horizontal projections of the heat dissipation section 21 and the flow cavity 101 on the central plane partially overlap. Both the arrangement of at least a portion of the heat dissipation section 21 opposite to the flow cavity 101, or the arrangement of at least a portion of the heat dissipation section 21 located within the flow cavity 101, allow the flowing air to pass through the flow cavity 101 and scour the heat dissipation section 21 of the controller 2, thereby enhancing the heat dissipation performance of the controller 2 and further contributing to the stable operation of the thermal management component 100.

[0025] like Figure 4 , Figure 5 and Figure 8 As shown, along the thickness direction of the main body 11, the included angle between the main body 11 and the cantilever 12 is A, where 0° < A < 180°. Within this angle range, it is beneficial for the heat dissipation part 21 of the controller 2 to dissipate heat. In addition, there is a reinforcing structure between the main body 11 and the cantilever 12. In this application, the reinforcing structure 102 refers to the reinforcing rib. The reinforcing rib is located at the connection between the main body 11 and the cantilever 12, which is beneficial for strengthening the load-bearing capacity of the cantilever 12.

[0026] Furthermore, the main body 11 includes a first end 111 and a second end 112, which are arranged opposite to each other. The first end 111 and the second end 112 are located on two sides of the main body 11, i.e., assuming there is a central plane between the first end 111 and the second end 112, the horizontal projections of the first end 111 and the second end 112 on the central plane partially overlap. The functional component 3 is fixedly connected or limited to the first end 111. In this application, the functional component 3 is threadedly connected to the first end 111. Due to space constraints, the valve component 31, the pump component 32, the sensor component 33, and the heat exchanger 34 are all concentrated in the first end 111, making the structure of the thermal management component 100 more compact. Of course, if space permits, the functional component 3 can be installed in both the first end 111 and the second end 112. The functional component 3 is integrated on the main body 11, and the controller 2 is integrated on the cantilever 12. This is beneficial for making effective use of the space of the flow channel plate 1. Compared with installing the controller 2 on the main body 11, it is beneficial to reduce the volume of the main body 11 and further make the structure of the flow channel plate 1 more compact.

[0027] like Figures 6-8 As shown, the controller 2 is installed at the end of the cantilever 12 away from the front of the vehicle. The heat dissipation part 21 of the controller 2 is rib-shaped and extends toward the opening end of the flow cavity 101. At least part of the flow cavity 101 is arranged toward the front of the vehicle. The cantilever portion 12 includes a first connecting arm 121, a second connecting arm 122, and a first wall portion 123. The first connecting arm 121, the second connecting arm 122, and the first wall portion 123 are plate-shaped structures. Along the thickness direction of the main body portion 11, the first wall portion 123 is located away from the main body portion 11 relative to the first connecting arm 121 and the second connecting arm 122. The first connecting arm 121 is connected to the main body portion 11, and the second connecting arm 122 is connected to the main body portion 11. One end of the first wall portion 123 is connected to the first connecting arm 121, and the other end is connected to the second connecting arm 122. The first connecting arm 121, the second connecting arm 122, and the first wall portion 123 are arranged in a direction perpendicular to the thickness direction of the main body portion 11. Along this direction, the first connecting arm 121 is located away from the first wall portion 123. The second connecting arm 122, the first connecting arm 121, and the second connecting arm 122 are on the same plane in the height direction. One end of the controller 2 is fixedly connected or limited to the first connecting arm 121, and the other end is fixedly connected or limited to the second connecting arm 122. For example, it can be fixed by welding, bonding, fastener fixing, or snap-fit ​​limiting. In this application, one end of the controller 2 is fixed to the first connecting arm 121 and the other end is fixed to the second connecting arm 122 by threaded connection. Threaded connection is convenient for maintenance and replacement. At the same time, it is convenient to adjust the position and preload of parts during assembly. In addition, compared with non-removable connections such as welding and riveting, threaded connection is low in cost and can be reused, further reducing maintenance costs.

[0028] The first connecting arm 121 includes a first mounting portion 121a and a first support portion 121b, with the first mounting portion 121a protruding relative to the first support portion 121b. The second connecting arm 123 includes a second mounting portion 122a and a second support portion 122b, with the second mounting portion 122a protruding relative to the second support portion 122b. In this application, the first mounting portion 121a and the second mounting portion 122a are located on the same plane, and the first support portion 121b and the second support portion 122b are located on the same plane. The first support portion 121b has reinforcing ribs 103, and the second support portion 122b has reinforcing ribs 103. The reinforcing ribs 103 are in a grid shape and are disposed on the first connecting arm 121, the second connecting arm 122, and the first wall portion 123. This structure is beneficial for optimizing materials, weight, and function while ensuring structural strength and stability, reducing the use of raw materials, lowering manufacturing costs, and reducing weight. The controller 2 is threadedly connected to the first mounting part 121a and the second mounting part 122a. To strengthen the connection between the controller 3 and the first mounting part 121a and the second mounting part 122a, a threaded metal insert (threaded sleeve) is added to the first mounting part 121a and the second mounting part 122a. The controller 2 is threadedly connected to the metal insert, which helps prevent loosening of the connection and facilitates installation and disassembly, making adjustment and assembly easier. For convenient positioning and installation, positioning posts are respectively provided on the first support part 121b and the second support part 122b. The corresponding controller 2 is provided with positioning holes and adjustable oblong holes to cooperate with them. By cooperating with the positioning holes, adjustable oblong holes and corresponding positioning posts, the assembly process can be simplified, while ensuring that the installation position of the controller 3 is determined, achieving high-precision and repeatable positioning, and effectively eliminating the cumulative error between parts. After positioning with positioning posts and fixing with bolts, the connection between the controller 2 and the first mounting part 121a and the second mounting part 122a is stable, effectively preventing the connection between the controller 2 and the flow channel plate 1 from loosening due to the influence of vehicle body vibration and temperature changes. The controller 2 is fitted with the first support 121b and the second support 122b with a clearance. During vehicle operation, the flowing air flows through the flow cavity 101 and washes over the heat dissipation part 21 of the controller 2. Then, the air flows out through the gap between the controller 2 and the first support 121b and the second support 122b, which helps to enhance the heat dissipation performance of the controller 2 and further ensures the stable operation of the thermal management component 100.

[0029] like Figures 5-10As shown, the wall portion forming the flow cavity 101 is located in the main body 11, partly in the first connecting arm 121, partly in the second connecting arm 122, and partly in the first wall portion 123. The flow cavity 101 has a first opening 101a and a second opening 101b. The second opening 101b is farther away from the controller 2 relative to the first opening 101a. The controller 2 includes a base plate 22, which is made of metal. Metal materials have better heat dissipation performance. In this application, the base plate 22 is made of aluminum alloy. The base plate 22 includes a heat dissipation portion 21 and a fixing portion 23. The fixing portion 23 is located around the heat dissipation portion 21. Part of the heat dissipation portion 21 is arranged opposite to the first support portion 121b and the second support portion 122b. That is, it is assumed that part of the heat dissipation portion 21 and the first support portion 121b and the second support portion 122b are... There is a central plane between them. Part of the heat dissipation part 21 and the horizontal projections of the first support part 121b and the second support part 122b on the central plane partially overlap. The heat dissipation part 21 extends towards the opening of the flow cavity 101. Simultaneously, the base plate 22 is fixedly connected to the first support part 121b and the second support part 122b, which also helps to enhance the overall strength of the cantilever part 12 and prevents the first support part 121b and the second support part 122b from deforming due to gravity during use. Furthermore, the fixed connection between the base plate 22 and the first support part 121b and the second support part 122b, because the base plate 22 is made of metal, allows for a relatively smaller thickness of the first support part 121b and the second support part 122b, which to some extent helps to reduce material costs. Figure 9 As shown, in this application, the heat dissipation part 21 is located at the first inlet 101a, and the second inlet 101b opens to receive the airflow during vehicle movement. The forward direction of the vehicle is the direction in which the first end 111 faces, so the airflow direction is opposite. During vehicle movement, air enters the flow chamber 101 from the second inlet 101b and flows towards the first inlet 101a, thus impacting the heat dissipation part 21 and enhancing the heat dissipation performance of the controller 2. The fixing part 23 has a mounting hole 231, and the fixing part 23 is threadedly connected to the cantilever part 12 through the mounting hole 231.

[0030] The above examples illustrate the principles and implementation methods of this utility model. The descriptions of these embodiments are merely for the purpose of helping to understand the technical solution and core ideas of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of this utility model.
