Description

Technical Field

[0001] The present application relates to the technical field of radiators, and in particular to a stress relief structure for an aluminum radiator. Background Art

[0002] like Figure 1 As shown, the existing aluminum radiator mainly includes end support plates, side support plates, heat pipes, fins, water inlet tanks and water outlet tanks. One reason is that during the production process, due to problems with production precision and assembly process, stress may exist between the components, especially after high-temperature brazing, which produces extremely high stress; the other reason is that during the operation of the radiator, due to frequent thermal expansion and contraction, the coolant and the radiator undergo thermal expansion and contraction, and the stress generated by the expansion coefficient of each component during operation is prone to deformation. If the stress is not released, the connection between the components is prone to breakage, causing coolant leakage, affecting the normal use of the radiator, and shortening its service life. Utility Model Content

[0003] In order to solve the above-mentioned problems, release stress, avoid breakage causing coolant leakage, ensure the normal use of the radiator, and increase the service life of the radiator, the present application provides an aluminum radiator stress release structure.

[0004] The present application provides an aluminum radiator stress relief structure that adopts the following technical solution.

[0005] A stress relief structure for an aluminum radiator, comprising: two side support plates, each of the upper and lower ends of the two side support plates being provided with an end support plate, the side support plates comprising a side plate A, and side plates B being provided on both sides of the side plate A extending toward one side of the side plate A;

[0006] The side support plate is provided with a release hole, which includes: a connecting hole opened in the transverse direction of the side plate A, end holes opened at both ends of the connecting hole, and a broken hole opened in the transverse direction of the side plate B, and the broken hole and the connecting hole are located at the same horizontal height.

[0007] By adopting the above technical solution, the stress of the side support plate can be eliminated by opening the release hole, and the side support plate is allowed to bend to a certain extent by opening the connecting hole, the end hole and the broken hole, thereby releasing various stresses and preventing the leakage of coolant in the radiator caused by fracture due to stress deformation.

[0008] Optionally, the end holes are symmetrically arranged up and down with the connecting hole as the center.

[0009] By adopting the above technical solution, the end hole is symmetrical up and down with the connecting hole as the center, so that the stress released at the upper and lower ends of the end hole can be the same, the force is evenly applied, and the structural shape of the side plate A is ensured.

[0010] Optionally, the end hole is arc-shaped, and the opening direction is toward the two side directions of the side plate A.

[0011] By adopting the above technical solution, the end hole is set in an arc shape, which can eliminate greater stress on the side panel A, while improving the structural toughness of the side panel A, reducing the rigidity and avoiding fracture.

[0012] Optionally, the broken hole is arranged to cut off the side panel B transversely.

[0013] By adopting the above technical solution, the broken hole cuts off the side plate B horizontally, which is equivalent to dividing the side plate B, thereby releasing the stress on the side plate B.

[0014] Optionally, the broken hole is opened to the connecting root of the side panel A and the side panel B, and is opened to the center of the arc-shaped end hole.

[0015] Optionally, the inner wall of the root of the broken hole is circular and concentric with the end hole.

[0016] By adopting the above technical solution and the structural design of the broken holes and end holes, the toughness of the side support plate can be improved, the rigidity can be reduced, and a larger floating amount can be allowed, which greatly reduces the probability of fracture due to stress.

[0017] Optionally, there are several release holes.

[0018] By adopting the above technical solution, multiple release holes are provided, which can release stress at multiple positions of the side support plate, thereby reducing the probability of fracture due to stress.

[0019] Optionally, the release holes on the two side support plates are aligned and distributed on both sides.

[0020] By adopting the above technical solution, the two sides are aligned and distributed, ensuring that the side support plates on both sides are evenly stressed, keeping the supporting forces on both sides balanced, and avoiding tilting and bending.

[0021] Optionally, the side support plate is made of U-shaped aluminum.

[0022] By adopting the above technical solution, the aluminum material has strong wear resistance, corrosion resistance, long service life, high strength and light weight, and is suitable for the production of radiators.

[0023] In summary, this application has at least the following beneficial effects:

[0024] 1. The present application can eliminate the stress of the side support plate by opening the release hole. By opening the connecting hole, the end hole and the broken hole, the side support plate is allowed to bend to a certain extent, thereby releasing various stresses and preventing the leakage of coolant in the radiator caused by fracture due to stress deformation.

[0025] 2. The present invention provides multiple release holes. Multiple release holes can release stress at multiple locations on the side support plates, reducing the probability of stress-induced fracture. The release holes on the two side support plates are aligned on both sides, ensuring uniform force on both sides and maintaining a balanced support force, thus preventing tilting and bending.

[0026] 3. The end holes of this application are arc-shaped, with their openings facing the sides of side panel A. This arc-shaped arrangement eliminates greater stress on side panel A, while also improving its structural toughness, reducing rigidity, and preventing fracture. The fracture holes are located at the connecting root of side panel A and side panel B, and at the center of the arc-shaped end holes. The inner wall of the fracture hole at its root is circular and concentric with the end hole. The structural design of the fracture hole and the end hole improves the toughness of the side support plate, reduces rigidity, and allows for greater floating capacity, significantly reducing the probability of fracture due to stress.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] The following is combined with Figures 1 to 8 This application is described in further detail.

[0039] An embodiment of the present application discloses a stress relief structure for an aluminum heat sink.

[0040] like Figure 1 As shown, the existing aluminum radiator mainly includes an end support plate 1, a side support plate 2, a heat pipe 3, a fin 4, a water inlet tank 5 and a water outlet tank 6. The upper and lower ends of the two side support plates are provided with end support plates 1. The end support plates 1 are spaced apart and provided with a number of heat pipe through holes 7. The upper and lower ends of the heat pipe 3 respectively pass through the heat pipe through holes 7 on the upper and lower end support plates 1. The water inlet tank 5 is fixed on the end support plate 1 at the upper end, and the water outlet tank 6 is fixed on the end support plate 1 at the lower end. The coolant in the water inlet tank 5 flows into the water outlet tank 6 through the heat pipe 3.

[0041] The end support plate 1, side support plate 2, heat pipe 3, fin 4, water inlet tank 5, and water outlet tank 6 are connected together by welding. One reason for this is that during the production process, due to production precision and assembly process issues, stress may exist between the various components, especially after high-temperature brazing, which generates extremely high stress. Another reason is that during the operation of the radiator, due to the frequent thermal expansion and contraction of the coolant and radiator, stress generated by the expansion coefficient of the various components during operation is prone to deformation. If the stress is not relieved, the connections between the components are prone to fracture, causing coolant leakage, affecting the normal use of the radiator, and shortening the radiator's service life.

[0042] Reference Figures 2 to 8 , an aluminum radiator stress relief structure, comprising:

[0043] Reference Figures 2 to 8 The side support plate 2 includes a side plate A8, and side plates B9 are provided on both sides of the side plate A8 and extend toward one side of the side plate A8.

[0044] The side support plate 2 can be made of U-shaped aluminum. Aluminum has strong wear resistance and corrosion resistance, and can ensure service life even in harsh and adverse environments. It has a long service life, high strength and light weight, and is suitable for the production of radiators.

[0045] Reference Figures 3 to 8 Side support plate 2 has two relief holes, including a connecting hole 10 extending transversely along side plate A8, end holes 11 extending from both ends of connecting hole 10, and a break hole 12 extending transversely along side plate B9. Break hole 12 is located at the same level as connecting hole 10. The relief holes relieve stress in side support plate 2. The connecting hole 10, end hole 11, and break hole 12 allow for a certain degree of bending in side support plate 2, thereby relieving various stresses and preventing radiator coolant leakage caused by stress deformation and fracture.

[0046] Each side support plate 2 has two relief holes, aligned on both sides. This arrangement allows for stress relief at multiple locations on the side support plates 2, reducing the likelihood of stress-induced fracture. This alignment ensures even stress distribution on both sides of the side support plates 2, maintaining a balanced support force and preventing tilting or bending.

[0047] Reference Figures 3 to 8 End holes 11 are arcuate and open toward the sides of side panel A8, so that the end holes 11 at both ends of connecting hole 10 face in opposite directions. End holes 11 are symmetrically arranged vertically with connecting hole 10 as the center. A broken hole 12 transversely bisects side panel B9 and extends from the connecting root of side panels A8 and B9 to the center of the arcuate end hole 11. The inner wall 13 of the broken hole at the center of broken hole 12 is circular and concentric with end hole 11.

[0048] The end hole 11 is set in an arc shape, which can eliminate the greater stress of the side panel A8, while improving the structural toughness of the side panel A8, reducing the rigidity, and avoiding fracture. The end hole 11 is symmetrical up and down with the connecting hole 10 as the center, so that the stress released at the upper and lower ends of the end hole 11 can be the same, the force is evenly distributed, and the structural shape of the side panel A8 is guaranteed. The broken hole 12 cuts off the side panel B9 horizontally, which is equivalent to dividing the side panel B9, thereby releasing the stress borne by the side panel B9. The structural design of the broken hole 12 and the end hole 11 can improve the toughness of the side support plate 2, reduce the rigidity, and allow a larger floating amount, greatly reducing the probability of fracture due to stress.

[0049] Similarly, more release holes can be opened on each side support plate 2. This embodiment mainly introduces the case of opening two release holes. There is no limit on the number of release holes. It can be calculated and adjusted according to the actual design of the radiator, which will not be elaborated here.

[0050] The thermal expansion coefficient of aluminum changes with temperature. Within a certain temperature range, the thermal expansion coefficient of aluminum is greater than that of steel. In the manufacturing process of aluminum materials, thermal expansion must be taken into consideration to avoid thermal stress or even cracks in high temperature environments.

[0051] Aluminum radiators frequently expand and contract during use, and aluminum has a high coefficient of thermal expansion. The stress relief structure's primary purpose is to relieve stress, or reduce the overall rigidity of the aluminum radiator, allowing some components to deform, thereby relieving stress and preventing breakage and coolant leaks, thereby extending the radiator's service life.
