Description

Technical Field

[0001] The utility model relates to the technical field of heat conduction pipes, in particular to a heat conduction pipe. Background Art

[0002] Heat pipes are widely used in devices involving heat transfer. Since some metals have good thermal conductivity, heat pipes are usually metal pipes with various cross-sectional shapes. In order to transfer heat to the greatest extent, the structure of the heat pipe has also been improved to a certain extent. For example, the authorized patent with application number CN201820555604.6 discloses a heat pipe, including a tube body, a sintered metal capillary wick and a heat transfer fluid; a mesh-shaped mesh groove is provided on the inner wall of the tube body; the sintered metal capillary wick is sintered on the inner wall of the tube body and covers the wall surface of the mesh groove; the heat transfer fluid is provided in the internal cavity of the tube body. The mesh groove includes a plurality of longitudinal grooves and a plurality of transverse grooves and other components.

[0003] The above solution is a single metal heat-conducting column. When in use, since the distance between the heat-conducting liquid at the center of the heat-conducting tube and the medium outside the heat-conducting tube is relatively far, the heat-conducting liquid at the center of the heat-conducting tube will first exchange heat with the heat-conducting liquid at the inner wall of the heat-conducting tube. Since the temperature difference between the two is small, the heat transfer inside the heat-conducting tube is slow, affecting the thermal conductivity of the heat-conducting tube. Based on this, the present application proposes a heat-conducting tube. Utility Model Content

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.

[0021] See also Figures 1 to 5 The utility model provides a heat pipe, including a heat pipe body, the inner cavity of the heat pipe body is divided into a heat exchange end 1 and a heat dissipation end 6, the inner cavity of the heat exchange end 1 is connected to the inner cavity of the heat dissipation end 6, and outwardly protruding convex grooves 2 are evenly provided on the pipe wall of the heat exchange end 1.

[0022] A capillary core 7 is fixed to the inner wall of the heat pipe body, and the inner cavity of the heat pipe body is filled with heat-conducting liquid 3. When the capillary core 7 absorbs heat, the heat-conducting liquid 3 in the capillary core 7 quickly vaporizes, and the vaporized heat-conducting liquid releases heat and condenses at the heat dissipation end 6, thereby realizing the recycling of the heat-conducting liquid.

[0023] Heat-conducting columns 5 are evenly and fixedly connected to the tube wall of the heat-conducting pipe body. One end of the heat-conducting column 5 is located outside the heat-conducting pipe body, and the other end of the heat-conducting column 5 is located in the middle of the inner cavity of the heat-conducting pipe body. The two adjacent heat-conducting columns 5 are staggered. Through the arrangement of the heat-conducting columns 5, the heat-conducting fluid at the center of the heat-conducting pipe can exchange heat with the fluid outside the heat-conducting pipe through the heat-conducting columns 5, thereby improving the thermal conductivity of the heat-conducting pipe.

[0024] A groove is provided in the middle of the above-mentioned heat-conducting column 5, and the inner cavity of the heat-conducting column 5 is connected with the inner cavity of the heat-conducting pipe body. Through the setting of the heat-conducting column 5, the inner cavity of the heat-conducting column 5 can be filled with heat-conducting liquid, further increasing the heat exchange area of ​​the heat-conducting pipe and improving the thermal conductivity of the heat-conducting pipe.

[0025] Heat transfer rods 4 are evenly fixed in the inner cavity of the heat exchange end 1. The heat transfer rods 4 are arranged along the length direction of the heat pipe body. One end of the heat transfer rod 4 is located in the inner cavity of the heat dissipation end 6, and the other end of the heat transfer rod 4 is located at the end of the heat exchange end 1 away from the heat dissipation end 6. Through the arrangement of the heat transfer rods 4, the heat transfer rods 4 can transfer heat inside the heat pipe, so that the heat around the heat conduction column 5 can be transferred to the heat conduction liquid away from the heat conduction column 5, thereby accelerating the speed of heat transfer inside the heat pipe, thereby improving the thermal conductivity of the heat pipe.

[0026] See also Figures 1 to 5The heat pipe body comprises an inner heat-conducting layer 10, with a first protective layer 8 fixed to its outer surface. A second protective layer 9 is also fixed to its outer surface. Both the first and second protective layers 8 and 9 are inlaid with thermally conductive ceramics, which are in contact with the inner heat-conducting layer 10. The first and second protective layers 8 and 9 protect the inner heat-conducting layer 10, making it corrosion-resistant and high-temperature-resistant. The thermally conductive ceramics also enhance the thermal conductivity of the inner heat-conducting layer 10.

The material of the first protective layer 8 is corrosion-resistant metal, and the outer surface of the first protective layer 8 is coated with a high-temperature resistant coating; the material of the inner thermal conductive layer 10 can be metallic copper.

When the heat pipe is in use, the heat transfer rod 4 quickly transfers the heat around the heat conduction column 5 to the heat conduction fluid away from the heat conduction column 5, thereby increasing the heat transfer speed inside the heat conduction fluid, thereby improving the heat conduction performance of the heat pipe; through the arrangement of the first protective layer and the second protective layer, the heat pipe has multiple protections, thereby improving the high temperature and corrosion resistance of the heat pipe and improving the adaptability of the heat pipe.
