Description

Technical Field

[0001] The invention relates to the technical field of automobile cooling modules, and in particular to a detachable plastic bracket of an aluminum heat exchanger. Background Art

[0002] The thermal management system of new energy vehicles needs to integrate multiple functions such as battery cooling, motor heat dissipation, and air conditioning refrigeration. The number and complexity of pipelines have increased significantly, and the heat dissipation requirements are also higher. Among them, the aluminum heat exchanger is installed on other heat exchangers or fans through various forms of connection structures, which can be snap connections, bolted connections, etc. At present, it is more common to weld the mounting bracket to the heat exchanger core.

[0003] However, the layout space of new energy vehicle models is limited. When there is a need to change the installation position, increase the number of installation points, or the position that the aluminum bracket cannot reach or the bracket shape is more complex, it is necessary to change the parts or tooling. The cost change is large and the change cycle is long, which makes it difficult to meet the rapid iteration needs of new energy vehicles. Summary of the invention

[0004] The purpose of the present invention is to address the deficiencies of the above-mentioned technology and provide a detachable aluminum heat exchanger plastic bracket. When the demand changes, there is no need to change the part core and welding process. Only a simple modification of the plastic bracket mold is required to meet the change demand.

[0005] To achieve the above-mentioned purpose, the detachable aluminum heat exchanger plastic bracket designed by the present invention includes a plastic bracket body, on which is provided a contoured structure, which matches the shape boundary of the heat exchanger core, and on which is provided a plurality of detachable interfaces for installing external devices.

[0006] Preferably, the contoured structure contours the outermost shape boundary of the collecting tube on the heat exchanger core.

[0007] Preferably, a plurality of contact convex strips parallel to the collecting tube are provided on the inner wall of the contoured structure to prevent the plastic support body from contacting and rubbing with the collecting tube to damage parts.

[0008] Preferably, the contact ridges are symmetrically distributed on the inner wall of the contoured structure.

[0009] Preferably, the interface includes a mounting groove structure provided on the plastic bracket body for mounting the heat exchanger core flange. The mounting groove structure is a square hole structure with a limit block boss provided inside. The limit block boss cooperates with the flange boss on the heat exchanger core flange to achieve fixed installation of the heat exchanger core flange on the mounting groove structure.

[0010] Preferably, an anti-hook structure protruding inwardly is provided at the opening of the mounting groove structure to prevent the heat exchanger core flange from falling off, and the anti-hook structure is provided with an outwardly expanding slope to facilitate the assemblability of the plastic bracket body.

[0011] Preferably, the interface may also be a boss hole structure or a clip structure, which may be designed according to customer needs and may be used to install different types of external devices.

[0012] Preferably, the contoured structure contours the liquid storage tank on the heat exchanger core, with an opening angle of 100±5 degrees and an installation bulge greater than 2 mm, further enhancing the stability of the installation of the plastic bracket body.

[0013] Preferably, the inner wall is provided with a groove structure cooperating with the boss on the surface of the liquid storage tank for positioning the plastic bracket body.

[0014] Preferably, the end surface of the contoured structure is designed with rounded corners to improve the assemblability of the plastic bracket body.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. When there is a need to change the installation position, increase the installation point requirements, or the position that the aluminum bracket cannot reach or the bracket shape is relatively complex, there is no need to change the core part of the aluminum heat exchanger, and a simple change at the sub-part level or a structure that the aluminum bracket cannot reach can be achieved, thereby reducing the part change cycle and cost;

[0017] 2. When changes are needed, there is no need to change the core of the parts and the welding process. It can be achieved by simply modifying the plastic bracket mold and changing the structure of the interface. There is no need to change the core of the heat exchanger to affect the welding quality and performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In this embodiment, another interface 13 is a boss hole structure 10, which is used to realize the customer's installation requirements. If the customer needs to modify or increase the installation requirements later, it can be achieved by changing the interface 13 without changing the heat exchanger core to affect the welding quality and performance.

[0035] Example 2

[0036] like Figure 1 As shown, a detachable aluminum heat exchanger plastic bracket includes a plastic bracket body 1, on which is provided a contoured structure 2, which matches the shape boundary of the heat exchanger core, and on which are provided two detachable interfaces 13 for installing external devices.

[0037] In this embodiment, if Figure 2 to Figure 6 As shown, the profiling structure 2 shaped the outermost shape boundary of the collecting pipe 3 on the heat exchanger core, and the plastic bracket body 1 was installed in cooperation with the collecting pipe 3 through the profiling structure 2. In this embodiment, the interface 13 includes a mounting groove structure 6 provided on the plastic bracket body 1 for mounting the heat exchanger core flange 5. The mounting groove structure 6 is a square hole structure with a limit block boss 7 provided inside. The limit block boss 7 cooperates with the flange boss 8 on the heat exchanger core flange 5 to achieve fixed installation of the heat exchanger core flange 5 on the mounting groove structure 6.

[0038] In this embodiment, another interface 13 is a boss hole structure 10, which is used to realize the customer's installation requirements. If the customer needs to modify or increase the installation requirements later, it can be achieved by changing the interface 13 without changing the heat exchanger core to affect the welding quality and performance.

[0039] In this embodiment, five contact ridges 4 parallel to the collecting tube 3 are provided on the inner wall of the profiling structure 2. The contact ridges 4 are symmetrically distributed on the inner wall of the profiling structure 2 to prevent the plastic bracket body 1 from contacting and rubbing with the collecting tube 3 to damage the parts.

[0040] Example 3

[0041] like Figure 1 As shown, a detachable aluminum heat exchanger plastic bracket includes a plastic bracket body 1, on which is provided a contoured structure 2, which matches the shape boundary of the heat exchanger core, and on which are provided two detachable interfaces 13 for installing external devices.

[0042] In this embodiment, if Figure 2 to Figure 6As shown, the profiling structure 2 shaped the outermost shape boundary of the collecting pipe 3 on the heat exchanger core, and the plastic bracket body 1 was installed in cooperation with the collecting pipe 3 through the profiling structure 2. In this embodiment, the interface 13 includes a mounting groove structure 6 provided on the plastic bracket body 1 for mounting the heat exchanger core flange 5. The mounting groove structure 6 is a square hole structure with a limit block boss 7 provided inside. The limit block boss 7 cooperates with the flange boss 8 on the heat exchanger core flange 5 to achieve fixed installation of the heat exchanger core flange 5 on the mounting groove structure 6.

[0043] In this embodiment, an anti-detachment hook structure 9 protruding inward is provided at the opening of the mounting groove structure 6 , and the anti-detachment hook structure 9 is provided with an outwardly expanding slope to facilitate the assembly of the plastic bracket body 1 .

[0044] In this embodiment, another interface 13 is a boss hole structure 10, which is used to realize the customer's installation requirements. If the customer needs to modify or increase the installation requirements later, it can be achieved by changing the interface 13 without changing the heat exchanger core to affect the welding quality and performance.

[0045] In the above embodiment, the interface 13 may also be a clip structure.

[0046] Example 4

[0047] like Figure 1 As shown, a detachable aluminum heat exchanger plastic bracket includes a plastic bracket body 1, on which is provided a contoured structure 2, which matches the shape boundary of the heat exchanger core, and on which are provided two detachable interfaces 13 for installing external devices.

[0048] In this embodiment, if Figure 7 to Figure 9 As shown, the contour structure 2 contours the shape of the liquid storage tank 11 on the heat exchanger core, such as Fig.10 As shown, since the condenser liquid storage tank 11 is usually designed as a cylinder with a smooth surface and no installation points, a semicircular structure that wraps the cylinder needs to be designed for the plastic bracket on the side of the liquid storage tank 11. After continuous 3D rapid printing physical verification, it is concluded that the design size X needs to be greater than 3mm and the opening angle α is 100±5° to facilitate assembly. The assembly is also stable and not easy to fall out, further enhancing the stability of the installation of the plastic bracket body 1. At the same time, the inner wall of the profiling structure 2 is provided with a groove structure 12 that cooperates with the boss on the surface of the liquid storage tank 11, which is used for positioning the plastic bracket body 1. The end face of the profiling structure 2 is designed with rounded corners to improve the assemblability of the plastic bracket body 1. In this embodiment, a solid structure is used to enhance the stability in the +X direction to prevent the plastic bracket body 1 from falling off.

[0049] The detachable aluminum heat exchanger plastic bracket of the present invention does not need to replace the core part of the aluminum heat exchanger when the installation position needs to be changed, the installation points need to be increased, or the position that the aluminum bracket cannot reach and the bracket shape is relatively complex. Simple changes at the sub-part level or structures that the aluminum bracket cannot reach can be achieved, thereby reducing the part change cycle and cost. When changes are needed, there is no need to change the part core and the welding process. It can be achieved by simply modifying the plastic bracket mold and changing the structure of the interface 13 without changing the heat exchanger core, thereby affecting the welding quality and performance.
