Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation structures, in particular to a heat dissipation structure that is beneficial to anodization. Background Art

[0002] Aluminum is a material with good thermal conductivity, so it is often used in the production of radiators. We generally call aluminum radiators aluminum profile radiators. All aluminum profiles here not only refer to aluminum, but also include aluminum alloy products. Aluminum is soft and has poor corrosion resistance, so aluminum profile radiators will undergo some necessary surface treatments, and anodizing is a common surface treatment method.

[0003] Anodizing usually refers to sulfuric acid anodizing, which is the process of forming an oxide film on the aluminum product (anode) under the action of an external current under the corresponding electrolyte and specific process conditions. This oxide film improves the surface hardness and wear resistance of the aluminum alloy, thereby expanding the scope of application and extending the service life of the aluminum profile radiator.

[0004] However, when the existing radiator is anodized, acid is very likely to remain inside the blind holes opened on the surface. During the entire oxidation process of the product and the final water washing, acid slowly seeps out, causing corrosion to the product. The surface of the product will have relatively dirty traces of acid corrosion. Therefore, a heat dissipation structure that is conducive to anodizing is proposed. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that when the existing radiator is anodized, acid is easily left inside the blind holes opened on the surface, causing corrosion of the product. The utility model provides a heat dissipation structure that is conducive to anodization.

[0006] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0007] A heat dissipation structure conducive to anodizing includes a heat sink, wherein the side wall of the heat sink is provided with a plurality of square holes distributed equidistantly in the horizontal direction, the side wall of the heat sink is provided with a plurality of strip grooves distributed in the horizontal direction, the side wall of the heat sink is provided with two groups of circular holes, each group of circular holes is composed of four circular holes, the internal hollow area of ​​each circular hole passes through the side wall of the heat sink, three threaded holes are provided on the top of the heat sink, threaded holes are provided on the bottom of the heat sink at positions corresponding to each threaded hole, and a connecting hole is provided between each of the two corresponding threaded holes above and below.

[0008] Furthermore, the inner hollow area of ​​each of the connecting holes 1 is composed of two mirror-distributed frustum structures.

[0009] Furthermore, the inner side wall surface of each of the strip-shaped grooves is a wavy plane.

[0010] Furthermore, three connection holes 2 are provided on the top of the radiator, a rotatable shaft is movably installed at the upper end of the connection holes 2 on both sides, and a rotatable shaft is movably installed at the lower end of the connection hole 2 in the middle, a rotating block is fixedly installed on the side wall of each rotating shaft, and a hanging hole is provided on the side wall of each rotating block.

[0011] Furthermore, the inner hollow area of ​​each of the second connecting holes is composed of two mirror-distributed trapezoidal terrace structures.

[0012] Furthermore, one end of each rotating block away from the adjacent rotating shaft is arranged in an arc surface.

[0013] The beneficial effects of the utility model are as follows:

[0014] 1. When the radiator is anodized, in order to avoid the problem of acid remaining inside the blind hole and then slowly seeping out, the inner hollow areas of the square hole and the round hole penetrate the side wall of the radiator, so the acid will not remain inside the square hole and the round hole. When the acid enters the inside of the threaded hole, since a connecting hole 1 is opened between each of the two corresponding threaded holes above and below, if there is residual acid inside the threaded hole, the acid will be discharged through the corresponding connecting hole 1, and will not accumulate inside the threaded hole for a long time, thereby affecting the subsequent oxidation process and the final water washing.

[0020] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. In addition, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0023] In the description of the embodiments of the present invention, it should be noted that the terms "inside", "outside", "upper", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0024] like Figures 1 to 4As shown, a heat dissipation structure conducive to anodization includes a heat sink 1, a side wall surface of the heat sink 1 is provided with a plurality of square holes 2 distributed equidistantly in the horizontal direction, a side wall surface of the heat sink 1 is provided with a plurality of strip grooves 3 distributed in the horizontal direction, a side wall surface of the heat sink 1 is provided with two groups of circular holes 4, each group of circular holes 4 is composed of four circular holes 4, the inner hollow area of ​​each circular hole 4 runs through the side wall surface of the heat sink 1, three threaded holes 5 are provided on the top of the heat sink 1, a threaded hole 5 is provided at the position corresponding to each threaded hole 5 at the bottom of the heat sink 1, and a connecting hole 6 is provided between each of the two corresponding threaded holes 5 above and below It should be noted that when the radiator 1 is anodized, in order to avoid the problem of acid remaining inside the blind hole and slowly seeping out later, the internal hollow areas of the square hole 2 and the round hole 4 both penetrate the side wall of the radiator 1, so the acid will not remain inside the square hole 2 and the round hole 4. When the acid enters the interior of the threaded hole 5, since a connecting hole 6 is provided between each of the two corresponding threaded holes 5 above and below, if there is residual acid inside the threaded hole 5, the acid will be discharged through the corresponding connecting hole 6 and will not accumulate inside the threaded hole 5 for a long time, thereby affecting the subsequent oxidation process and the final water washing.

[0025] like Figure 2 As shown, the internal hollow area of ​​each connecting hole 6 is composed of two mirror-distributed truncated cone structures. It should be noted that when the radiator 1 is anodized, if the radiator 1 is placed horizontally, the acid liquid entering the threaded hole 5 will further flow into the interior of the connecting hole 6 and be discharged from the interior of the connecting hole 6. If the radiator 1 is placed vertically, the acid liquid entering the connecting hole 6 will flow downward and be discharged from the interior of the connecting hole 6 because the internal hollow area of ​​the connecting hole 6 is composed of two mirror-distributed truncated cone structures.

[0026] like Figure 1 , Figure 4 As shown, the inner side wall surface of each strip groove 3 is a wavy plane. It should be noted that the inner side wall surface of the strip groove 3 is a wavy plane, which can increase the contact area with the air and dissipate heat more quickly during heat dissipation.

[0027] like Figure 1 , Figure 3As shown, three connecting holes 27 are provided on the top of the radiator 1, and a rotatable shaft 8 is movably installed at the upper ends of the connecting holes 27 on both sides, and a rotatable shaft 8 is movably installed at the lower end of the connecting hole 27 in the middle, and a rotating block 9 is fixedly installed on the side wall of each rotating shaft 8, and a hanging hole 10 is provided on the side wall of each rotating block 9. It should be noted that before anodizing the radiator 1, each rotating block 9 can be rotated separately, and each rotating block 9 drives the rotating shaft 8 connected to it to rotate. After each rotating block 9 is rotated out of the corresponding connecting hole 27, the hooks of the anodizing hanger are respectively passed through the inside of the three hanging holes 10, and the radiator 1 is fixed in three directions for later processing.

[0028] like Figure 3 As shown, the internal hollow area of ​​each connecting hole 27 is composed of two mirror-distributed trapezoidal terrace structures. It should be noted that when the radiator 1 is anodized, no matter the radiator 1 is placed horizontally or vertically, the acid liquid entering the interior of the connecting hole 27 will be discharged from the outlets at both ends of the connecting hole 27.

[0029] like Figure 3 As shown, one end of each rotating block 9 away from the adjacent rotating shaft 8 is arranged in an arc surface. It should be noted that it can be ensured that the rotating block 9 can be smoothly rotated out from the inside of the corresponding second connecting hole 7.
