Description

Technical Field

[0001] This utility model relates to the field of thermal management system technology, and in particular to a flow channel plate with a quick-connect port. Background Technology

[0002] As a component in the thermal management system of new energy vehicles, the flow channel plate has a large number of quick-connect pipes with uniform specifications, making it difficult to demold. Therefore, in the mass production stage, the pipes are usually injection molded separately and then connected to the main body of the flow channel plate by hot plate welding.

[0003] During the product trial production stage, small batches of prototypes need to be made. They are usually formed as a whole using SLS printing, without the need for disassembly. However, since the dimensional accuracy and roughness requirements of the sealing surface formed by printing the pipe opening do not meet the sealing requirements, secondary processing on a CNC machine tool is required.

[0004] Due to the large number of pipe openings and their inconsistent orientations, each pipe opening needs to be individually centered and machined to ensure the installation and sealing performance of fittings. This requires multiple clamping operations based on the pipe opening orientation. However, this necessitates the fabrication of various tooling fixtures to fix multiple pipe openings separately or the use of a horizontal milling machine to machine the sealing surfaces of multiple pipe openings. This process is cumbersome, inefficient, and prone to errors, leading to product quality defects or scrap. Utility Model Content

[0005] In view of this, it is necessary to provide a flow channel plate with quick-connect pipe ports to solve the problem of having to make multiple tooling to fix multiple pipe ports separately or to use a horizontal milling machine to process the sealing surfaces of multiple pipe ports. This process is cumbersome, has low processing efficiency, and is prone to errors, resulting in product quality defects or scrap.

[0006] This utility model provides a flow channel plate with a quick-connect tube port, including a flow channel plate body and a tube head. The flow channel plate body has a first mating part; the tube head has a second mating part for mating and connecting with the first mating part.

[0007] Furthermore, one of the first mating part and the second mating part is an internal thread, and the other is an external thread that can mate with the internal thread.

[0008] Furthermore, the flow channel plate also includes sealant filled between the external thread and the internal thread.

[0009] Furthermore, the nominal diameter of both the external thread and the internal thread is 20~30mm, and the pitch is 1~4mm.

[0010] Furthermore, the tube head is a tubular structure, and the interior of the tube head is connected to the inlet and outlet of the flow channel on the main body of the flow channel plate.

[0011] Furthermore, the cross-section of the formed surface of the tube head increases along the direction close to the main body of the flow channel plate.

[0012] Furthermore, the structure also includes an annular boss formed on the outer wall of the pipe head, and a limiting groove is provided on the flow channel plate body. The annular boss can be engaged in the limiting groove to limit the installation position of the pipe head relative to the flow channel plate body.

[0013] Furthermore, both the flow channel plate body and the pipe head are made of 3D printing material and are integrally formed by 3D printing.

[0014] Furthermore, the main body of the flow channel plate has a mounting hole, the inner wall of the mounting hole has an internal thread, and the outer wall of the end of the pipe head has an external thread, and the pipe head is connected to the internal thread of the main body of the flow channel plate via the external thread thereon.

[0015] Furthermore, there are multiple tube heads, and each of the multiple tube heads is detachably connected to the main body of the flow channel plate.

[0016] Compared with existing technologies, the flow channel plate body and the tube head can be 3D printed independently, enabling mass production. The forming surface of each tube head is processed to obtain a sealing surface with the required dimensional and roughness accuracy. No tooling is required; the sealing surface of the tube head can be processed by machine tools. The processed tube head is then connected to the flow channel plate body, effectively improving production efficiency and processing stability. Attached Figure Description

[0017] Figure 1 A schematic diagram of the overall external structure of the flow channel plate with quick-connect tube port provided for an embodiment of this utility model;

[0018] Figure 2 This is a schematic diagram of the overall internal structure of the flow channel plate with quick-connect tube opening provided in an embodiment of the present invention. Detailed Implementation

[0019] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0020] like Figure 1-2 As shown, the present invention provides a flow channel plate with a quick-connect tube port, including a flow channel plate body 100 and a tube head 200. The flow channel plate body 100 has a first mating part, and the tube head 200 has a second mating part for mating and connecting with the first mating part.

[0021] In practice, the flow channel plate body 100 and the tube head 200 can be independently 3D printed and mass-produced. The forming surface 210 of each tube head 200 is processed to obtain a sealing surface with the required dimensional and roughness accuracy. No tooling is required. The processing of the sealing surface of the tube head 200 can be realized by machine tool. Then the processed tube head 200 is connected to the flow channel plate body 100, which effectively improves production efficiency and processing stability.

[0022] In this embodiment, both the flow channel plate body 100 and the tube head 200 are made of 3D printed material and are integrally formed by 3D printing. The forming surface 210 of the tube head 200 is formed into a sealing surface by a turning process, wherein the machining allowance of the turning process is 1~1.5mm.

[0023] To achieve a detachable connection between the flow channel plate body 100 and the pipe head 200, in one embodiment, one of the first mating part and the second mating part is an internal thread, and the other is an external thread that can mate with the internal thread.

[0024] The flow channel plate body 100 has a mounting hole with an internal thread 110 on its inner wall. The outer wall of the end of the pipe head 200 has an external thread 220, and the pipe head 200 is connected to the internal thread 110 of the flow channel plate body 100 via the external thread 220. Alternatively, the internal thread can be provided on the inner wall of the mounting hole, and the external thread can be provided on the pipe head 200.

[0025] To ensure the sealing of the threaded connection between the pipe head 200 and the flow channel plate body 100, in this embodiment, the structure also includes a sealant filled between the external thread 220 and the internal thread 110. The sealant can be AB glue. Before connecting the pipe head 200 and the flow channel plate body 100, the AB glue is applied to the threads. After the pipe head 200 is screwed all the way in, the AB glue fills the thread gaps, thus ensuring sealing and connection strength. Excess glue is wiped clean, without affecting the product appearance.

[0026] It is understandable that the external thread 220 of the pipe head 200 and the internal thread 110 of the flow channel plate body 100 can be directly formed by 3D printing. The thread accuracy requirement is not high, there is no requirement for the starting position of the thread, the operation is simple, and it does not affect the product appearance and installation requirements.

[0027] In one embodiment, the nominal diameter of both the external thread and the internal thread is 20-30 mm, and the pitch is 1-4 mm. Preferably, the nominal diameter of both the external thread 220 and the internal thread 110 is 24 mm, and the pitch is 2 mm.

[0028] In this embodiment, the tube head 200 is a tubular structure. Before being connected to the flow channel plate body 100, the outer wall of the tube head 200 has a molding surface 210, and the interior of the tube head 200 is connected to the flow channel inlet and outlet on the flow channel plate body 100. The cross-section of the molding surface 210 of the tube head 200 increases along the direction close to the flow channel plate body 100.

[0029] In one embodiment, the flow channel plate further includes an annular boss 230 formed on the outer wall of the tube head 200. A limiting groove 120 is formed on the flow channel plate body 100, and the annular boss 230 can be engaged in the limiting groove 120 to limit the installation position of the tube head 200 relative to the flow channel plate body 100. This effectively ensures the height of the tube head 200 relative to the flow channel plate body 100. The thread depth is 8mm to ensure connection strength, while a 0.5mm gap is maintained at the bottom of the external thread 220 to ensure no interference during installation.

[0030] The device includes multiple pipe heads 200, each of which is detachably connected to the flow channel plate body 100. The multiple pipe heads 200 should be installed sequentially according to their predetermined directions.

[0031] Compared with existing technologies, the flow channel plate body 100 and the tube head 200 can be independently 3D printed, enabling mass production. The forming surface 210 of each tube head 200 is processed to obtain a sealing surface with the required dimensional and roughness accuracy. No tooling is required; the processing of the sealing surface of the tube head 200 can be achieved through a machine tool. The processed tube head 200 is then connected to the flow channel plate body 100, effectively improving production efficiency and processing stability.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
