Description

Technical Field

[0001] The utility model relates to the technical field of flow channel plates, in particular to a flow channel plate component and a thermal management integrated module. Background Art

[0002] The flow channel plate is a carrier of the coolant, and the design of its internal flow channel structure will affect the flow resistance. For example, a sudden 90° turn of the flow channel structure or a sudden change in cross-sectional area at a corner will affect the fluid lift performance. Therefore, the prior art rounds the corners of the flow channel structure to make the transition of the fluid relatively smooth when flowing.

[0003] However, due to the influence of the parting surface height of the runner plate, the radius of the runner plate at the turning position in the prior art is limited, which cannot make the runner plate transition more smoothly and the flow resistance performance is not optimized enough. Utility Model Content

[0004] The utility model aims to provide a flow channel plate assembly and a thermal management integrated module, so that the flow channel plate can transition more smoothly and have better flow resistance performance.

[0005] In order to solve the above technical problems, the utility model provides a flow channel plate assembly, including a first flow channel plate and a second flow channel plate, the first flow channel plate has a first cavity, the second flow channel plate has a second cavity, the first flow channel plate and the second flow channel plate are buckled with each other, the first cavity and the second cavity enclose at least part of the flow channel cavity, one end of the second flow channel plate has an extension section, the extension section extends in a direction away from the first flow channel plate, and the end of the extension section facing away from the first flow channel plate is an open end;

[0006] The flow channel cavity includes a first flow channel section, a transition section and a second flow channel section. The inner part of the extension section forms the second flow channel section. The extension direction of the first flow channel section and the extension direction of the second flow channel section are set at an angle. The inner wall of the first flow channel plate includes a first wall portion and an arc-shaped guide wall portion. The first wall portion forms a partial side wall of the first flow channel section, and the guide wall portion forms a partial side wall of the transition section. Within the extension range of the guide wall portion, the flow area of ​​the transition section is equal.

[0007] The utility model also provides a thermal management integrated module, comprising the aforementioned flow channel plate assembly, and thermal management system components, wherein the thermal management system components are all installed on the flow channel plate assembly.

[0008] The technical effects of the utility model are as follows:

[0009] In the flow channel plate assembly of the utility model, the inner wall of the first flow channel plate is provided with an arc-shaped guide wall portion in the transition section, that is, the arc-shaped guide wall portion is provided on the outer side of the corner to guide the fluid to turn. After entering the first flow channel section, the fluid can smoothly enter the transition section from the first flow channel section under the guiding action of the guide wall portion, and realize turning under the guiding action of the guide wall portion. At the same time, within the extension range of the guide wall portion, the flow area of ​​the transition section is equal. Taking into account factors such as processing errors, as long as the error is within an acceptable range, the flow area of ​​the transition section can be considered to be equal. In short, within the extension range of the guide wall portion, the flow area of ​​the transition section no longer changes suddenly, thereby reducing the flow resistance in the process of fluid turning, reducing the energy loss of the fluid, ensuring that the fluid can complete the turning more smoothly, and the fluid head performance is better.

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] The “plurality” mentioned herein generally means more than two; and when “plurality” is used to indicate the number of certain components, it does not indicate the relationship between the quantities of these components.

[0022] Please refer to Figure 1-Figure 4 , Figure 1 A split diagram of a specific embodiment of the flow channel plate assembly provided by the utility model; Figure 2 for Figure 1 A cross-sectional view of the flow channel plate assembly along the vertical direction; Figure 3 for Figure 2 A cross-sectional view of the first flow channel plate; Figure 4 for Figure 1 Simulation diagram of fluid flow state in the flow channel plate assembly;.

[0023] The utility model provides a flow channel plate assembly, including a first flow channel plate 1 and a second flow channel plate 2, the first flow channel plate 1 has a first cavity 1a, the second flow channel plate 2 has a second cavity 2a, the first flow channel plate 1 and the second flow channel plate 2 are buckled with each other, the first cavity 1a and the second cavity 2a enclose at least part of the flow channel cavity, one end of the second flow channel plate 2 has an extension section 2a1, the extension section 2a1 extends in a direction away from the first flow channel plate 1, and the end of the extension section 2a1 facing away from the first flow channel plate 1 is an open end;

[0024] The flow channel cavity includes a first flow channel section a1, a transition section a2 and a second flow channel section a3. The inner part of the extension section 2a1 forms the second flow channel section a3. The extension direction of the first flow channel section a1 and the extension direction of the second flow channel section a3 are arranged at an angle. The inner wall of the first flow channel plate 1 includes a first wall portion 12 and an arc-shaped guide wall portion 11. The first wall portion 12 forms a partial side wall of the first flow channel section a1, and the guide wall portion 11 forms a partial side wall of the transition section a2. Within the extension range of the guide wall portion, the flow area of ​​the transition section a2 is equal.

[0025] In the flow channel plate assembly of the utility model, the inner wall of the first flow channel plate 1 is provided with an arc-shaped guide wall portion 11 in the transition section a2, that is, the arc-shaped guide wall portion 11 is provided on the outer side of the corner to guide the fluid to turn. After entering the first flow channel section a1, the fluid can smoothly enter the transition section a2 from the first flow channel section a1 under the guiding action of the guide wall portion, and realize the turning under the guiding action of the guide wall portion 11. At the same time, within the extension range of the guide wall portion 11, the flow area of ​​the transition section a2 is equal. Taking into account factors such as processing errors, as long as the errors are within an acceptable range, the flow areas of the transition sections a2 can be considered to be equal. In short, within the extension range of the guide wall portion 11, the flow area of ​​the transition section a2 no longer changes suddenly, thereby reducing the flow resistance in the process of fluid turning, reducing the energy loss of the fluid, ensuring that the fluid can complete the turning more smoothly, and the fluid head performance is better.

[0026] As described above, the extension direction of the first flow channel section a1 and the extension direction of the second flow channel section a3 are set at an angle. This embodiment is aimed at the case where the angle between the first flow channel section a1 and the second flow channel section a3 is approximately 90°. Taking into account the processing error, the angle between the first flow channel section a1 and the second flow channel section a3 is slightly greater than or slightly less than 90°, such as 88°, 92°, etc., which can be considered that the angle between the first flow channel section a1 and the second flow channel section a3 is approximately 90°. In addition, the angle between the first flow channel section a1 and the second flow channel section a3 can also be greater than 90°, such as 100°, 110°, etc., and can be set according to actual needs.

[0027] like Figure 2 As shown, in this embodiment, the guide wall portion 11 and the first wall portion 12 are tangentially connected, and the first flow channel plate 1 is also provided with a water inlet I, which is connected to the first cavity 1a, and the water inlet I is located at one end of the first wall portion 12 away from the guide wall portion 11, and the open end of the lower end of the extension section 2a1 forms a water outlet O.

[0028] In this way, the fluid can enter the first flow channel section a1 from the water inlet I, then smoothly enter the transition section a2 from the first flow channel section a1 to achieve a turn, then enter the second flow channel section a3 from the transition section a2, and finally flow out from the water outlet O.

[0029] like Figure 2 As shown, in this embodiment, the tangent direction of one end of the guide wall portion 11 away from the first wall portion 12 is along the extension direction of the second flow channel segment a3.

[0030] As described above, within the extension range of the guide wall portion 11, the fluid can complete the flow diversion from the first direction to the second direction. The first direction is the extension direction of the first flow channel segment a1, and the second direction is the extension direction of the third flow channel segment a3. Therefore, when the fluid flows out from the lower end of the guide wall portion 11, the fluid will have the following Figure 3As shown in the flow performance, the flow direction of the fluid is consistent with the extension direction of the third flow channel segment a3, and can thus smoothly enter the interior of the third flow channel segment a3 and continue to flow downward along the extension direction of the third flow channel segment a3, further reducing the flow resistance during the fluid turning process and reducing the energy loss of the fluid.

[0031] It can be understood that, in fact, the inner wall of the first flow channel plate 1 may include not only the guide wall portion 11, but also an extension wall portion tangently connected to the guide wall portion 11, and the extension direction of the extension wall portion is consistent with the extension direction of the second flow channel section a3. Of course, in fact, due to the limited height of the first flow channel plate 1, in this embodiment, the lower end structure of the guide wall portion 11 and the extension wall portion may protrude from the open end surface of the first flow channel plate 1. The longer the length of the protruding portion, the more difficult it is to form the first flow channel plate 1, and the higher the possibility of the protruding portion breaking under the action of the fluid. Therefore, the inner wall of the first flow channel plate 1 only includes the guide wall portion 11, and the tangent direction of the lower end of the guide wall portion 11 along the extension direction of the second flow channel section a3 can also achieve the same technical effect, with low molding difficulty and not easy to break, which is a more preferred technical solution.

[0032] Please continue to refer to 1 and Figure 2 and Figure 5 , Figure 5 for Figure 2 A partial enlarged view of the middle guide wall.

[0033] In this embodiment, the free end of the guide wall portion 11 protrudes from the open end surface of the first flow channel plate 1 .

[0034] As configured above, the guide wall portion 11 can utilize the internal space of the second cavity 2a to guide the fluid to complete the turning. In this way, the height of the first flow channel plate 1 can be reduced, thereby reducing the overall volume of the flow channel plate and the space occupied by the flow channel plate, thereby facilitating the layout. In addition, the length of the protruding portion is shorter, the molding difficulty is low, and it is not easy to break.

[0035] Of course, in practice, if the flow channel plate has sufficient installation space, the height of the first flow channel plate 1 can be increased so that the guide wall portion 11 can guide the fluid to complete the turning inside the first cavity 1a. At this time, it is also feasible that the free end of the guide wall portion 11 is flush with the opening end surface of the first flow channel plate 1.

[0036] Please continue to refer to Figure 2 , Figure 5 and Figure 6 , Figure 6 for Figure 1 A schematic structural diagram of the first flow channel plate in the flow channel plates.

[0037] Depend on Figure 6It can be seen that the opening end surface of the first flow channel plate 1 is provided with a protrusion 13 , the inner wall of the protrusion 13 forms a part of the structure of the guide wall portion 11 , and there is a gap between the outer wall of the protrusion 13 and the corresponding side wall of the second flow channel plate 2 .

[0038] As set above, firstly, there is a spacing between the outer wall of the protrusion 13 and the corresponding side wall of the second flow channel plate 2, allowing the first flow channel plate 1 and the second flow channel plate 2 to have a certain processing error, avoiding the situation where the installation cannot be performed, and ensuring the reliable installation of the first flow channel plate 1 and the second flow channel plate 2; secondly, in practice, the matching end faces of the first flow channel plate 1 and the second flow channel plate 2 are fixed by welding, and there is a spacing between the outer wall of the protrusion 13 and the corresponding side wall of the second flow channel plate 2 to play a role in heat insulation, avoiding the heat transfer to the protrusion 13 during welding, causing the protrusion 13 to be heated, softened and deformed, thereby ensuring the structural stability of the guide wall portion 11, and further ensuring that the fluid can smoothly complete the turning under the guidance of the guide wall portion 11.

[0039] Please continue to refer to Figure 2 In this embodiment, the inner wall of the second flow channel plate 2 includes a second wall portion 21, an arcuate wall portion 22 and a third wall portion 23. The second wall portion 21 forms a partial side wall of the first flow channel section a1, the arcuate wall portion 22 forms a partial side wall of the transition section a2, and the third wall portion 23 forms a partial side wall of the second flow channel section a3. The second wall portion 21 and the arcuate wall portion 22 are tangentially connected, and the third wall portion 23 and the arcuate wall portion 22 are tangentially connected.

[0040] As configured above, the flow channel cavity also smoothly transitions on the inner side of the corner through the arc-shaped wall portion 22, and the fluid near the lower side of the flow channel cavity can smoothly complete the turn under the guidance of the arc-shaped wall portion 22, further improving the flow resistance performance of the fluid.

[0041] Of course, in practice, it is also feasible to connect the second wall portion 21 and the third wall portion 23 at a right angle. For example, the guide wall portion 11 can be extended with the connection point between the second wall portion 21 and the third wall portion 23 as the center of the circle. At this time, the central angle of the guide wall portion 11 is 90°, and the flow area of ​​the transition section a2 is always equal, thereby reducing the flow resistance during the fluid turning process and reducing the fluid energy loss.

[0042] In this embodiment, the first flow channel plate 1 and the second flow channel plate 2 are both made of plastic and are formed by injection molding. The first flow channel plate 1 and the second flow channel plate 2 are fixed together by welding, and the connection is reliable and has good sealing performance.

[0043] The utility model also provides a thermal management integrated module, comprising the aforementioned flow channel plate assembly and thermal management system components, wherein the thermal management system components are all installed on the flow channel plate assembly.

[0044] The thermal management integrated module of the present invention includes the aforementioned flow channel plate assembly, and thus has the same technical effects as the aforementioned flow channel plate assembly, which will not be described in detail herein.

[0045] Among them, the thermal management system components include water valves, water pumps, etc. The specific structures of the thermal management system components are existing technologies well known to those skilled in the art and will not be repeated here.

[0046] The above is a detailed introduction to a flow channel plate assembly and a thermal management integrated module provided by the utility model. This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the method and core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
