Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy welding wires, in particular to a special-section aluminum welding wire for welding a water-cooled aluminum radiator. Background Art

[0002] Water-cooled aluminum radiators are mainly used in computer hardware or other electronic devices that require efficient heat dissipation. The core components of this type of radiator are made of aluminum. Through the precise internal water channel structure, the coolant circulates in it, thereby transferring heat from the heating element (such as the CPU or GPU) to the radiator, and then through contact with the water cooling row, the heat is discharged from the system with the help of fans and other means to achieve a cooling effect. Aluminum is widely used in radiator manufacturing due to its good thermal conductivity, lightness and cost-effectiveness. Compared with traditional air-cooled heat dissipation, the water cooling system has higher heat dissipation efficiency, especially suitable for high-performance computing and overclocking applications, and can effectively control the temperature to ensure stable operation of the hardware.

[0003] Water-cooled aluminum radiators generally use aluminum shells. In order to ensure that the airtightness failure rate after welding is within 3%-5% and to ensure that the internal coolant does not leak, the aluminum shells are generally welded by fusion welding. They are placed under vacuum conditions and a heat source is used to melt the matrix and welding wire to form a molten pool. The inventor of this application uses a special connection structure between aluminum shells of water-cooled aluminum radiators, such as Figure 1 As shown, the aluminum shell of the water-cooled aluminum radiator includes a cover protrusion 2 and a base groove 3. The cross-section of the cover protrusion 2 is a downward convex shape, and the cover protrusion 2 is composed of a cover bottom surface 21 and two cover inclined surfaces 22 symmetrical about the center line of the cover bottom surface 21. The cross-section of the base groove 3 is an upward concave shape, and the base groove 3 is composed of a base top surface 31 and two base inclined surfaces 32 symmetrical about the center line of the base top surface 31. When the existing cylindrical welding wire is used to weld the cover protrusion 2 and the base groove 3, it is found that the airtightness defect rate of the water-cooled aluminum radiator after welding exceeds 50%, which does not meet the use conditions. Therefore, it is necessary to design a welding wire specifically for this aluminum shell with a special connection structure. Utility Model Content

[0004] The utility model provides a special-section aluminum welding wire for welding water-cooled aluminum radiators to solve the problem that the existing welding wire cannot meet the special connection structure between aluminum shells and the airtightness failure rate after welding is kept within 3%-5%. The specific technical solution is as follows:

[0005] A special-section aluminum welding wire for welding a water-cooled aluminum radiator, characterized in that the special-section aluminum welding wire comprises a welding wire body, an upper concave portion is formed on the upper part of the welding wire body, and a lower convex portion is formed on the lower part of the welding wire body; the upper concave portion forms a groove bottom surface, the cross-sectional length of the groove bottom surface is shorter than the cross-sectional length of the bottom surface of a cover plate by less than 0.3 mm, groove shoulders are formed on both sides of the groove bottom surface, and the angle of the groove shoulder relative to the groove bottom surface is the same as the angle of the cover plate inclined surface relative to the cover plate bottom surface; and the lower convex portion forms a lower convex bottom surface, the cross-sectional length of the lower convex bottom surface is longer than the cross-sectional length of the top surface of the base by less than 0.3 mm, lower convex inclined surfaces are formed on both sides of the lower convex bottom surface, and the angle of the lower convex inclined surface relative to the lower convex bottom surface is the same as the angle of the base inclined surface relative to the top surface of the base.

[0006] Preferably, the upper concave section, the bottom surface of the cover plate and the inclined section of the cover plate can be combined into a curve opening upward, the lower convex section, the top surface of the base and the inclined section of the base can also form a curve opening upward, the groove shoulder is symmetrical about the center line of the groove bottom surface, and the lower convex inclined surface is symmetrical about the center line of the lower convex bottom surface.

[0007] It can be seen from the above technical solution that the utility model has the following beneficial effects:

[0008] The utility model designs the welding wire into a shape with a cross section that is concave at the top and convex at the bottom. The upper concave portion of the welding wire body and the convex portion of the cover plate jointly form a curve with an opening upward, and the shoulder of the groove can cooperate with the inclined surface of the cover plate to prevent the coolant inside the radiator from overflowing from the connection with the aluminum shell; the lower convex portion of the welding wire body and the base groove jointly form a curve with an opening upward, and the lower convex inclined surface can cooperate with the inclined surface of the base to prevent the coolant inside the radiator from overflowing from the connection with the aluminum shell, thereby maintaining the airtightness defect rate of the water-cooled aluminum radiator within 3%-5%.

[0015] like Figure 1 As shown, the aluminum shell of the water-cooled aluminum radiator welded in the embodiment of the utility model includes a cover plate protrusion 2 and a base groove 3. The cross section of the cover plate protrusion 2 is a downward convex shape. The cover plate protrusion 2 is composed of a cover plate bottom surface 21 and two cover plate inclined surfaces 22 symmetrical about the center line of the cover plate bottom surface 21.

The base inclined surface 32 has the same angle as the cover plate inclined surface 22 and a similar cross-sectional length, so that the cover plate inclined surface 22 can form an upward opening curve together with the base inclined surface 32, thereby reducing the internal coolant from overflowing from the connection, thereby improving the anti-leakage performance of the aluminum shell connection.

[0016] like Figure 2 As shown, the embodiment of the utility model comprises a welding wire body 1, the cross section of which is concave at the top and convex at the bottom, wherein an upper concave portion 11 is formed at the upper portion, and a lower convex portion 12 is formed at the lower portion.

The groove shoulders 112 are symmetrical about the center line of the groove bottom surface 111, and the angle of one side of the groove shoulder 112 adjacent to the groove bottom surface 111 relative to the groove bottom surface 111 is the same as the angle of the cover inclined surface 22 relative to the cover bottom surface 21, so that the upper recess 11 can cover the cover protrusion 2, thereby improving the guarantee of air tightness during welding.

[0018] Specifically, the cross-sectional shape of the lower convex portion 12 is also a curve opening upward, with a lower convex bottom surface 124 formed in the middle position. The cross-sectional length of the lower convex bottom surface 124 is within 0.3 mm longer than the cross-sectional length of the base top surface 31, and lower convex inclined surfaces 123 are formed on both sides of the lower convex bottom surface 124. The lower convex inclined surfaces 123 are symmetrical about the center line of the lower convex bottom surface 124, and the angle of one side of the lower convex inclined surface 123 adjacent to the lower convex bottom surface 124 relative to the lower convex bottom surface 124 is the same as the angle of the base inclined surface 32 relative to the base top surface 31, so that the base groove 3 can cover the lower convex portion 12, thereby improving the guarantee of air tightness during welding.

[0019] Combination Figure 1 to Figure 2 The welding wire body 1 is designed to have a cross-section with a concave upper portion and a convex lower portion. The upper concave portion 11 of the welding wire body 1 and the cover plate protrusion 2 together form a curve with an opening upward, and the groove shoulder 112 can cooperate with the cover plate inclined surface 22 to prevent the coolant inside the radiator from overflowing from the connection with the aluminum shell; the lower convex portion 12 of the welding wire body 1 and the base groove 3 together form a curve with an opening upward, and the lower convex inclined surface 123 can cooperate with the base inclined surface 32 to prevent the coolant inside the radiator from overflowing from the connection with the aluminum shell, thereby maintaining the airtightness defect rate of this water-cooled aluminum radiator within 3%-5%.
