Description

Technical Field

[0001] The present application relates to the technical field of thermal management systems, and in particular to a fluid control component and a thermal management system. Background Art

[0002] The fluid control components in the thermal management system include a flow plate and a pump, wherein the pump is usually fixed to the flow plate in an inverted installation manner, and the flow plate is provided with an interface for communicating with the liquid inlet and liquid outlet of the pump. The pump is fixed to the flow plate so that the liquid inlet and liquid outlet of the pump face the flow plate above and are connected with the interface provided on the flow plate.

[0003] The structures of the flow plates of different fluid control components are different, and the installation space on the surface of the flow plate may also be different, which can easily lead to limited installation space for the pump on the surface of the flow plate. When the fluid control component needs to be replaced with a different pump, the structure of the interface of the flow plate may also need to be changed accordingly, which requires replacement of the entire flow plate, which is costly. Utility Model Content

[0004] The purpose of this application is to provide a fluid control component and a thermal management system, which facilitates the installation of the pump on the flow plate and reduces the requirements for the surface space of the flow plate. At the same time, when replacing different pumps, there is no need to replace the flow plate, which has good flexibility and can effectively reduce costs.

[0005] In order to solve the above-mentioned technical problems, the present application provides a fluid control component, including a flow channel plate, a adapter and a pump; a flow channel is arranged in the flow channel plate; the adapter is fixedly connected to the flow channel plate, and the adapter is provided with a first flow channel and a second flow channel respectively connected to the flow channel; the pump is fixed to the adapter, and the pump is provided with a first flow port and a second flow port, the first flow port is connected to the first flow channel, and the second flow port is connected to the second flow channel.

[0006] The present application also provides a thermal management system, including a water tank and the fluid control component as described above, wherein the flow channel plate of the fluid control component is provided with a water replenishment port connected to the flow channel, and the water outlet of the water tank is connected to the water replenishment port.

[0007] The pump is not directly fixedly connected to the flow channel plate. During installation, first fix the adapter part to the flow channel plate, and then fix the pump to the adapter part. Through the first flow channel and the second flow channel provided in the adapter part, the liquid inlet and outlet of the pump are respectively communicated with the flow channel, so as to realize the circulation of the liquid in the flow channel driven by the pump. After the pump is fixed to the flow channel plate, it is only necessary to make the first flow channel and the second path communicate with the flow channel. The specific structure of the adapter part fixedly attached to the flow channel plate can be set according to the specific structure of the surface of the flow channel plate and the space situation, so that the structural and space requirements of the surface of the flow channel plate can be reduced and the flexibility can be improved. Moreover, the pump is installed on the adapter part, and the adapter part is provided with an installation structure adapted to the pump. When replacing different pumps for this fluid control component, there is no need to replace the flow channel plate, and only the corresponding adapter part needs to be replaced, which has good flexibility and low cost.

[0008] For different fluid control components, the structure of the flow channel plate may be different. For example, the layout of the flow channels in the flow channel plate is different, the number of pumps to be installed (i.e., the number of fixed adapter parts) is different, etc. As a result, corresponding molds are required for the preparation of each flow channel plate. By setting the adapter part as a separate structure, it is convenient to set it as a standard part and only a single unified mold is needed for preparation. The structures of the interfaces of the flow channel plate for fixing to the adapter part are the same, so that the structure and cost of the production mold can be effectively reduced.

[0009] Moreover, when replacing different pumps, there is no need to replace the flow channel plate, and only the corresponding adapter part needs to be replaced, which has good flexibility and can effectively reduce costs. Description of the Drawings

[0026] In order to enable those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] The embodiment of the present application provides a fluid control component and a thermal management system. The thermal management system can be a vehicle thermal management system, etc. The thermal management system is used to adjust the temperature inside the vehicle.

[0028] The thermal management system includes a water tank 4 and a fluid control component as shown in Figure 1 the figure. Among them, the fluid control component includes a flow channel plate 1 and a pump 3. A flow channel 14 and a water replenishing port are arranged in the flow channel plate 1. The flow channel 14 is communicated with the circulation loop in the thermal management system. The water replenishing port is communicated with the flow channel 14. Water is stored in the water tank 4. The water outlet 41 of the water tank 4 is communicated with the water replenishing port for replenishing water into the flow channel 14. The liquid inlet and outlet of the pump 3 are respectively communicated with the flow channel 14 and are used to provide power for the liquid circulation in the flow channel 14.

[0029] The flow channel 14 in the flow channel plate 1 is a hole structure arranged in the flow channel plate 1. The flow channel plate 1 can be an integrally injection-molded structure or a two-piece structure. Specifically, it includes an upper plate part and a lower plate part. At least one of the upper plate part and the lower plate part is provided with a groove structure. After the upper plate part and the lower plate part are fixed, the flow channel 14 can be formed at the groove structure.

[0030] Such asFigure 1 As shown, the fluid control component further includes an adapter portion 2, which is an independent structure from the flow channel plate 1 and is fixedly connected thereto. The adapter portion 2 is provided with a first flow channel 21 and a second flow channel 22. When the adapter portion 2 is in a fixed state with the flow channel plate 1, the first flow channel 21 and the second flow channel 22 are respectively communicated with the flow channels 14 in the flow channel plate 1.

[0031] The pump 3 is fixed to the adapter portion 2. The pump 3 is provided with a first fluid port 31 and a second fluid port 32. Specifically, the first fluid port 31 can be the liquid inlet and the second fluid port 32 can be the liquid outlet, or the first fluid port 31 can be the liquid outlet and the second fluid port 32 can be the liquid inlet. After the pump 3 is fixed to the adapter portion 2, the first fluid port 31 is communicated with the first flow channel 21, and the second fluid port 32 is communicated with the second flow channel 22. Thus, the liquid inlet and the liquid outlet of the pump 3 are respectively communicated with the flow channels 14, and at this time, the pump 3 can provide a flow power for the liquid in the flow channels 14.

[0032] That is to say, in this embodiment, the pump 3 is not directly fixedly connected to the flow channel plate 1. During installation, first fix the adapter portion 2 to the flow channel plate 1, and then fix the pump 3 to the adapter portion 2. Through the first flow channel 21 and the second flow channel 22 provided in the adapter portion 2, the liquid inlet and the liquid outlet of the pump 3 are respectively communicated with the flow channels 14, realizing the flow of the liquid in the flow channels 14 driven by the pump 3. After the pump 3 is fixed to the flow channel plate 1, it is only necessary to make the first flow channel 21 and the second path communicate with the flow channels 14. The specific structure of the adapter portion 2 fixedly attached to the flow channel plate 1 can be set according to the specific structure and space conditions of the surface of the flow channel plate 1. In this way, the structural and space requirements of the surface of the flow channel plate 1 can be reduced, and the flexibility can be improved. Moreover, the pump 3 is installed on the adapter portion 2, and the adapter portion 2 is provided with an installation structure adapted to the pump 3. When replacing different pumps 3 for this fluid control component, there is no need to replace the flow channel plate 1, and only the corresponding adapter portion 2 needs to be replaced, which has good flexibility and low cost.

[0033] For different fluid control components, the structure of the flow channel plate 1 may be different. For example, the layout of the flow channels 14 in the flow channel plate 1 is different, and the number of pumps 3 for installation (i.e., the number of fixed adapter portions 2) is different, etc. As a result, corresponding molds are required respectively for the preparation of each flow channel plate 1. By setting the adapter portion 2 as a separate structure, it is convenient to set it as a standard part and it can be prepared using a single unified mold. The structure of the interface of the flow channel plate 1 for fixing to the adapter portion 2 is consistent. In this way, the structure and cost of the production mold can be effectively reduced.

[0034] Moreover, when replacing different pumps, there is no need to replace the flow channel plate, and only the corresponding adapter portion needs to be replaced, which has good flexibility and can effectively reduce costs.

[0035] The pump 3 and the adapter 2 are also respectively provided with positioning structures that are adapted to each other. When the pump 3 and the adapter 2 are in a fixed state, they can be positioned and fitted through the mutually adapted positioning structures, so that the first flow port 31 and the first flow channel 21 are communicated, and the second flow port 32 and the second flow channel 22 are communicated. Positioning through the positioning structure can avoid multiple adjustments during the installation process, thereby improving the installation efficiency.

[0036] Specifically, as Figure 9 shown, the pump 3 is provided with an installation part 33, and both the first flow port 31 and the second flow port 32 are arranged on the installation part 33. The adapter 2 is provided with an installation groove 23 adapted to the installation part 33 (as Figure 5 shown). When the pump 3 and the adapter 2 are in a fixed state, as Figure 10 and Figure 11 shown, the installation part 33 can be positioned and fitted with the installation groove 23. The shape, structure, size, etc. of the inner wall of the installation groove 23 are all adapted to the shape, structure, size, etc. of the outer peripheral wall of the installation part 33. Specifically, no restrictions are imposed on the specific structures of the installation part 33 and the installation groove 23, and the structure of the installation groove 23 can be set according to the specific structure of the installation part 33.

[0037] The groove wall forming the installation groove 23 is also provided with a first groove 24 and a second groove 25. The groove wall can specifically be a groove side wall or a groove bottom wall. Among them, the first groove 24 is communicated with the first flow channel 21, and the second groove 25 is communicated with the second flow channel 22. When the pump 3 and the adapter 2 are in a fixed state, the installation part 33 is located in the installation groove 23, the first flow port 31 is communicated with the first groove 24, and the second flow port 32 is communicated with the second groove 25. At the same time, the end face of the installation part 33 can also be in sealing fit with the groove wall in the area between the first groove 24 and the second groove 25 to ensure the connection sealing performance.

[0038] Specifically, no specific restrictions are imposed on the structures and positions of the first groove 24 and the second groove 25, and they can be set according to the relative positions of the first flow port 31 and the second flow port 32 of the pump 3.

[0039] When the first flow port 31 of the pump 3 is arranged at the central position of the installation part 33, as Figure 5 shown, the bottom of the installation groove 23 is provided with a first groove 24 and a second groove 25. Among them, the second groove 25 is an annular groove, the first groove 24 is coaxially arranged with the second groove 25, and the first groove 24 is located at the central position of the bottom of the installation groove 23. The radius dimension of the second groove 25 is the same as the distance between the first flow port 31 and the second flow port 32.

[0040] As Figure 6 、 Figure 7 and Figure 8As shown, the depth of the first groove 24 is greater than that of the second groove 25. An interface communicating with the above-mentioned first flow channel 21 is provided on the groove side wall of the first groove 24, and an interface communicating with the above-mentioned second flow channel 22 is provided on the groove side wall of the second groove 25. Moreover, along the axial direction of the first groove 24, the first flow channel 21 is located on the side of the second groove 25 away from the pump 3. With such a setting, it can be ensured that the first flow channel 21 is not communicated with the second groove 25.

[0041] After fixing the pump 3 to the adapter part 2, the installation part 33 is installed in the installation groove 23. The first communication port 31 can be correspondingly communicated with the first groove 24, and then communicated with the first flow channel 21. The second communication port 32 can be communicated with any position of the second groove 25, and then communicated with the second flow channel 22. With such a setting, the installation part 33 and the installation groove 23 only need to position the installation of the pump 3 in the radial direction. When installing the pump 3, it can freely rotate around the axis of the installation part 33 to any angle, and it can be ensured that the first communication port 31 is communicated with the first flow channel 21 through the first groove 24, and the second communication port 32 is communicated with the second flow channel 22 through the second groove 25.

[0042] The first groove 24 forms an interface for the first flow channel 21 to communicate with the first communication port 31, and the second groove 25 forms an interface for the second flow channel 22 to communicate with the second communication port 32. The installation of the pump 3 in the radial direction is limited by the installation part 33 and the installation groove 23. The settings of the first groove 24 and the second groove 25 can ensure corresponding communication while facilitating the adjustment of the installation angle of the pump 3. In this way, for the pumps 3 arranged at different positions, their installation angles can be adjusted according to the specific usage situation. The overall structure is simple and has good flexibility.

[0043] As Figure 1 shown, the end of the adapter part 2 is fixed to the surface of the flow channel plate 1, and the pump 3 is fixedly arranged on the side wall part of the adapter part 2. Specifically, in the use state as Figure 1 shown, both the adapter part 2 and the pump 3 are located below the flow channel plate 1. In this way, the installation method of the pump 3 is inverted, and its axis is in a state approximately parallel to the surface of the flow channel plate 1. Compared with the scheme of directly installing the pump 3 on the bottom of the flow channel plate 1 so that the axis of the pump 3 is perpendicular to the surface of the flow channel plate 1, it can reduce the overall height of the fluid control assembly, reduce the space occupied in the height direction, and facilitate the arrangement of the fluid control assembly in a limited installation space.

[0044] As Figure 3 and Figure 4 shown, the surface of the flow channel plate 1 protrudingly is provided with a fixing part 11, a first connecting part 12 and a second connecting part 13. Among them, the fixing part 11 is provided with two connecting interfaces, namely a first connecting interface 111 and a second connecting interface 112, and these two connecting interfaces are respectively communicated with the flow channel 14.

[0045] A first connection channel is provided in the first connection part 12, and a second communication channel is provided in the second connection part 13. Among them, the first connection channel communicates between the flow channel 14 and the first connection interface 111, and the second communication channel communicates between the flow channel 14 and the second connection interface 112. The settings of the first connection part 12 and the second connection part 13 facilitate the fixing part 11 to be arranged at any position of the flow channel plate 1. Specifically, the specific positions of the pump 3 and the adapter part 2 can be determined according to the installation space situation, and the flexibility is better.

[0046] After the adapter part 2 is fixed to the fixing part 11, the first connection interface 111 can communicate with the first flow channel 21, and the second connection interface 112 can communicate with the second flow channel 22.

[0047] As Figure 2 shown, the pump 3 is arranged at the edge of the surface of the flow channel plate 1, making full use of the surface of the flow channel plate 1 to fix the pump 3 at a position close to the edge of the flow channel plate 1 to avoid interference with other components.

[0048] In this embodiment, there is no limitation on the fixing method between the adapter part 2 and the fixing part 11. For example, it can be welded or fixed by fasteners or other methods. The fixing part 11 protrudes from the surface of the flow channel plate 1, which can also increase the thickness and structural strength of the flow channel plate 1 at this place and ensure the installation stability of the adapter part 2. There is no limitation on the installation method between the adapter part 2 and the pump 3. For example, it can be fixed by fasteners arranged circumferentially. Of course, it can also be fixed by clamping or other methods. When fixed by fasteners, the fixing stability can be ensured.

[0049] The above is only the preferred embodiment of the present application. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present application, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
