[0028] In the above-mentioned heat dissipation copper tube, the copper foil replaces the copper powder layer, which reduces the cost of the product. At the same time, it avoids the use of the copper powder layer in the entire circle of the copper tube body, which leads to large thermal resistance and affects the heat dissipation effect; the copper foil is arranged in the cooling part, and the other parts of the copper tube body have low thermal resistance, which helps to quickly dissipate heat, thereby improving the heat dissipation effect; the copper foil is designed with a capillary path to achieve local control to increase or decrease the thickness, thereby increasing or decreasing the heat wattage.

[0029] In the prior art, a copper powder layer is used, and quantitative powder filling will cause powder falling due to vibration, resulting in insufficient powder, which in turn makes the automated process capability more difficult and wastes copper powder. The present application uses copper foil to replace the copper powder layer, thereby enhancing the automated process capability and improving the convenience of the automated equipment process.

[0030] The copper foil piece has a plurality of copper foil holes, each of which is arranged in sequence and is extended along the radial direction of the copper tube body.

[0031] Each copper foil hole forms a capillary path, and the capillary path is arranged in a circuitous manner, so as to realize local control to increase or decrease the thickness, thereby realizing strengthening or weakening the heating wattage.

[0032] The installation groove is arranged in an outwardly arched arc shape, the copper foil piece is arranged in an outwardly arched arc shape, and the copper foil piece is flatly embedded in the installation groove; the coverage area of ​​the copper foil piece is increased, and the thermal interaction area of ​​the copper foil piece is increased, which is convenient for heat dissipation, thereby improving the heat dissipation effect.

[0033] The copper foil piece has a copper foil surface facing inwards, and the inner wall of the copper tube body is arranged flush with the copper foil surface, which facilitates the matching of the copper foil piece and the copper tube body.

[0034] The installation groove includes two side groove walls and a bottom groove wall. The two side groove walls are arranged correspondingly. The two ends of the bottom groove wall are respectively connected to the side groove walls. The two side groove walls clamp the copper foil piece. Along the inward direction, the two side groove walls are gradually arranged in a flared shape, which facilitates the assembly of the copper foil piece and the copper tube body and enhances the stability of the assembly of the copper foil piece and the copper tube body.

[0035] The heat dissipation copper tube includes a plurality of heat dissipation fins, which are arranged in a flat shape, and each heat dissipation fin is arranged in sequence at intervals, and the copper tube body passes through each heat dissipation fin in sequence; under the action of each heat dissipation fin, heat is easily dissipated.

[0036] The heat sink is made of aluminum, which has better thermal conductivity and facilitates heat dissipation.

[0037] The heat dissipation copper tube includes a positioning plate, which is arranged in a ring shape and is arranged on a copper tube body. The positioning plate is arranged between adjacent heat dissipation fins, and both ends of the positioning plate are respectively connected to the adjacent heat dissipation fins. Under the action of the positioning plate, the arrangement of adjacent heat dissipation fins is enhanced.

[0038] The positioning pieces are arranged in a circuitous manner, and the positioning pieces form a heat dissipation channel, and the heat dissipation channel is arranged in an irregular circuitous manner; the heat dissipation channel formed by the positioning pieces forms an air duct, which is convenient for airflow to carry heat, thereby achieving other heat dissipation effects.

[0039] The invention comprises a copper tube body, which comprises a straight tube portion and a curved portion. The curved portion and the straight tube portion are integrally formed, and an end cap is arranged at the end of the straight tube portion. The copper tube body utilizes the straight tube portion and the curved portion to conduct heat to the end cap to complete heat dissipation. The copper tube body is hollow and a fixing groove is arranged on one side of the inner wall. A porous copper foil is arranged in the fixing groove, and the porous copper foil is fixed to the copper tube body through a fixing mechanism.

[0040] In this embodiment, the depth of the fixing groove is adapted to the porous copper foil, and the fixing mechanism is arranged on the bottom wall of the fixing groove. The fixing mechanism penetrates the porous copper foil to achieve fixation, thereby ensuring that the inner wall of the copper tube body is a whole plane.

[0041] In this embodiment, the fixing mechanism includes a fixing column 9 evenly arranged on the bottom wall of the fixing groove, an extension rod is arranged on one side of the fixing column 9, and a lower convex portion is arranged at the lower part of the extension rod, and the diameter of the lower convex portion decreases from the fixing column 9 to the end away from the fixing column. A through hole is arranged on the porous copper foil for the fixing column to pass through, and a fixing plate is arranged on the upper side of the through hole. Both ends of the fixing plate are connected with side plates, and the side plate and the fixing plate are fixed on the porous copper foil at the edge of the through hole. A concave groove is arranged in the middle of the top of the fixing plate, and a wear-resistant layer is arranged in the concave groove. The wear-resistant layer contacts with the lower convex portion when the porous copper foil moves, and finally completes the abutment fixation. The fixation is completed by abutting the lower convex portion with the concave portion, thereby ensuring that the connection between the porous copper foil and the copper tube body is stable.

[0042] In this embodiment, the side of the fixed plate facing the through opening is a sliding opening, and the porous copper foil moves to achieve interlocking and fixing of the lower convex portion and the fixed plate. An anti-slip layer is provided on the outer wall of the lower convex portion, and the anti-slip layer and the wear-resistant layer are pressed against each other to complete the fixation, and the stability is strong.

[0043] When the technical solution is in use, the lower convex part and the concave part are abutted to complete the fixation, so as to ensure the stable connection between the porous copper foil and the copper tube body. The porous copper foil is provided to reduce the thermal resistance of the copper tube body. The porous copper foil is used instead of copper powder, which is convenient for processing. The thickness of the porous copper foil can be partially increased to increase the wattage of heat dissipation. The use of copper powder will increase the thermal resistance because the inner wall of the entire circle of the copper tube is copper powder, while the porous copper foil reduces the thermal resistance, improves the heat dissipation efficiency, increases the heat conductivity, and enhances the thermal conductivity effect.

[0044] Experimental example

[0045] Now the existing copper tube body (copper powder) and the copper tube body of this technical solution are tested for heat dissipation;

[0046] Test samples, take two copper tubes, namely the existing copper tube (sample 1) and the copper tube of this technical solution (sample 2), turn them over in a computer case for testing, the two computers have the same configuration for temperature measurement, and the measurement results are as follows:

[0047] Sample 1 Sample 2 1h 40.1℃ 35.8℃ 2h 50.6℃ 45.3℃ 5h 48.6℃ 45.6℃ 10h 47.2℃ 43.3℃ 15h 49.9℃ 44.1℃ 20h 49.3℃ 44.3℃ 24h 48.6℃ 45.1℃

[0048] It can be seen from the above table that the temperature of the existing copper tube body (sample 1) that also dissipates heat for the computer is lower than that of the copper tube body (sample 2) of the present technical solution, and the copper tube body (sample 2) achieves rapid heat dissipation through porous copper foil to ensure that the heat is lower than that of the existing copper tube body (sample 1). Therefore, the use of copper powder will increase the thermal resistance because the inner wall of the entire copper tube is copper powder, while the porous copper foil reduces the thermal resistance and improves the heat dissipation efficiency.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
