Description

Technical Field

[0001] This utility model relates to the field of radiator technology, specifically to a heat sink with enhanced end strength. Background Technology

[0002] The heat dissipation core of the existing radiator consists of a protective plate, heat dissipation strips, heat dissipation pipes, and sealing blocks. The protective plates are placed on both sides, multiple heat dissipation pipes are arranged side by side, and sealing blocks are connected between the ends of adjacent heat dissipation pipes. The heat dissipation strips are located between the ends of adjacent heat dissipation pipes, thus forming the heat dissipation core.

[0003] The existing heat sink end is in contact with the sealing block, and this area is subjected to the force of the sealing block. Its compressive strength is lower than that of the middle section of the heat sink. To ensure the strength at this point, such as... Figure 11 As shown, the current practice involves inserting reinforcing fins into the inner cavity of the heat sink. However, inserting reinforcing fins is a complex and inefficient process, and there is a risk that the fins may detach from the heat sink. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a heat dissipation pipe with enhanced end strength.

[0005] This utility model is achieved through the following technical solution: a heat dissipation pipe with reinforced end strength is provided, comprising two parallel pipe walls. Reinforcing connecting portions are provided at both ends of the pipe walls along their length. Each reinforcing connecting portion has multiple end protrusions protruding inwards from the heat dissipation pipe. Corresponding end protrusions on the two pipe walls are fitted and fixed together. In this solution, the end protrusions at both ends of the pipe walls achieve connection and reinforcement. These positions are connected to a sealing block, and the fitting and fixing of corresponding end protrusions on the two pipe walls prevents the heat dissipation pipe from collapsing and deforming after the sealing block applies pressure, thereby improving the strength of the heat dissipation pipe ends.

[0006] As an optimization, the end protrusion is elongated and its length direction is parallel to the length direction of the heat sink. This increases the range of reinforcement in the length direction, ensuring that all sealing block positions are reinforced through the end protrusion.

[0007] As an optimization, the reinforced connection portion has at least two rows of end protrusions along the length of the heat dissipation pipe. This multi-row end protrusions achieve a reinforcing effect.

[0008] As an optimization, the pipe wall has a central convex section located between two reinforcing connecting parts, and the corresponding central convex sections on the two pipe walls are fitted and fixed together. In this design, the central convex section reinforces the middle section of the heat dissipation pipe.

[0009] As an optimization, one end of the two pipe walls is connected by multiple continuous bends, with adjacent bends fitting tightly together. The other end is connected by a connecting structure, which includes a U-shaped connecting part that fits snugly against one pipe wall and a folded connecting part that connects to the other pipe wall. The folded connecting part is inserted into the U-shaped connecting part. In this solution, the heat dissipation pipe is formed by bending a sheet metal, with multiple continuous bends achieving connection at one end, and the other end is connected via the folded connecting part and the U-shaped connecting part.

[0010] As an optimization, the folded connection is a double-bent section, thereby improving the connection strength at this point.

[0011] As an optimization, both sides of the U-shaped connector are double-bent.

[0012] The beneficial effects of this utility model are as follows: The end-strength-reinforced heat dissipation tube of this utility model has two ends of the tube wall connected and reinforced by protrusions at the ends, and then brazed together after entering the furnace with the core. This position is connected to the sealing block, and the two tube walls are fixed together by the corresponding end protrusions, which ensures that the area of ​​the sealing block in contact with the heat dissipation tube completely supports the heat dissipation tube, thereby preventing the heat dissipation tube from collapsing and deforming after the sealing block applies pressure to the heat dissipation tube, improving the strength of the end of the heat dissipation tube. The protrusions can also divert water or gas, increase turbulence, and improve heat dissipation performance. Attached Figure Description

[0026] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0027] Example 1:

[0028] like Figures 1-11 As shown, the present invention provides a heat dissipation pipe with enhanced end strength, comprising two parallel pipe walls 1, the two ends of which are connected in the width direction to form a hollow tubular structure.

[0029] like Figure 5 , 8 As shown, in this embodiment, one end of the two pipe walls 1 in the width direction is connected by multiple continuous bends 6, and the adjacent bends in the multiple continuous bends 6 are closely fitted. In this embodiment, a 6-layer structure is formed by 5 180-degree bends, and the 6-layer structure is fixed by brazing to improve the strength at this point.

[0030] like Figure 5 , 6 As shown, the other ends of the two pipe walls 1 in the width direction are connected by a connecting structure. The connecting structure includes a U-shaped connecting part 4 that fits into one pipe wall 1 and a folded connecting part 5 that fits into the other pipe wall 1. The two sides of the U-shaped connecting part 4 fit into the inner sides of the two pipe walls 1 respectively. The folded connecting part 5 is double-bent and inserted into the U-shaped connecting part 4, thereby forming a 6-layer structure. The 6-layer structure is fixed by brazing to improve the strength at this point.

[0031] The tube wall 1 has reinforcing connecting parts at both ends along its length. The reinforcing connecting parts fit into the sealing blocks between adjacent heat dissipation tubes, thereby strengthening the heat dissipation tubes at that location. The reinforcing connecting parts have multiple end protrusions 2 that protrude into the heat dissipation tubes. The ends of the end protrusions 2 are flat, so that the corresponding end protrusions 2 on the two tube walls 1 can fit together and be fixed, and then brazed together after the core is put into the furnace.

[0032] The end protrusion 2 is elongated and its length direction is parallel to the length direction of the heat sink pipe. Multiple end protrusions 2 are evenly distributed along the width direction of the pipe wall 1. The distance from the end of the end protrusion 2 away from the end of the heat sink pipe to the end of the heat sink pipe is L1. The length of the sealing block 9 that is attached to the heat sink pipe 8 is L, and L1 is greater than L, ensuring that the area where the sealing block contacts the heat sink pipe is completely supported by the end protrusion 2.

[0033] Example 2:

[0034] The pipe wall 1 is provided with a central protrusion 3 located between two reinforcing connecting parts, and the corresponding central protrusions 3 on the two pipe walls 1 are fitted and fixed together. The central protrusions 3 are arranged in a rectangular array on the pipe wall 1.

[0035] Example 3:

[0036] The reinforced connection part has at least two rows of end protrusions 2 along the length of the heat dissipation pipe. The distance from the end of the end protrusion 2 away from the end of the heat dissipation pipe to the end of the heat dissipation pipe is L2. The length of the sealing block 9 that is in contact with the heat dissipation pipe 8 is L, and L2 is greater than L, so that the area where the sealing block contacts the heat dissipation pipe is fully supported by the end protrusions 2.

[0037] like Figure 9 , 10 As shown, there are sealing blocks 9 and heat dissipation strips 10 between the ends of adjacent heat dissipation pipes 8, and the two sides of the entire core are protected by protective plates 7.

[0038] like Figure 11 As shown, in the prior art, reinforcing fins 11 are inserted into the inner cavity at the end of the heat sink. The process of inserting reinforcing fins is relatively complex and inefficient, and there is a risk that the reinforcing fins will detach from the heat sink.

[0039] Example 4:

[0040] like Figure 7 As shown, the two sides of the U-shaped connecting part 4 are respectively attached to the inner sides of the two pipe walls 1, and both sides of the U-shaped connecting part 4 are double-bent. The folded connecting part 5 is a single layer and is inserted into the U-shaped connecting part 4, thereby forming a 6-layer structure. The 6-layer structure is fixed by brazing to improve the strength at this point.

[0041] Of course, the above description is also not limited to the above examples, the technical features not described in the utility model can be realized by or using the prior art, which will not be repeated here; the above embodiments and drawings are only used to illustrate the technical scheme of the utility model and are not a limitation on the utility model, the utility model has been described in detail with reference to the preferred embodiments, and those skilled in the art should understand that the changes, modifications, additions or replacements made by those skilled in the art within the essential scope of the utility model do not deviate from the purpose of the utility model, and should also belong to the protection scope of the claims of the utility model.
