[0002] A heat pipe is a hollow cylindrical tube. When a temperature difference occurs between its two ends, the liquid at the evaporating end will quickly vaporize, carrying heat to the condensing end. During the production process of heat pipes, it is usually necessary to fill the hollow copper tube with copper powder and coolant to ensure the heat dissipation performance of the heat pipe.

The above components achieve the effect that, by providing the restraining ring 2 and positioning block 3, the position of the central support rod 1 can be restricted when the central support rod 1 is installed in a hollow copper tube.

[0030] The following is a detailed description of its overall specific settings and functions.

[0031] Reference Figure 1-Figure 5As shown, in this embodiment: the end of the rotating rod 4 close to the constraint ring 2 is fixedly connected to the support plate 11, and the end of the central support rod 1 close to the support plate 11 is fixedly connected to the positioning plate 12. The effect achieved by the above components is: by setting the rotating rod 4, the support plate 11 can be conveniently controlled to rotate, and by setting the positioning plate 12, a positioning effect can be achieved during the rotation of the support plate 11. The end of the rotating rod 4 close to the limiting ring 5 is fixedly connected to the rotating plate 6, and the side of the rotating plate 6 is fixedly connected to the arc plate 7. The effect achieved by the above components is: by setting the rotating plate 6, the arc plate 7 can be installed on the rotating rod 4, and by setting the rotating plate 6, the rotating rod 4 can be conveniently controlled to rotate. A threaded rod 8 is threadedly inserted into the inner wall of the arc plate 7, and the threaded rod 8 is fixedly connected to the mounting plate 9 at the end close to the rotating rod 4, and a rubber pad 10 is glued to the side of the mounting plate 9 close to the central support rod 1. The effects achieved by the above components are: the threaded rod 8 threadedly inserted into the inner wall of the arc-shaped plate 7 can rotate. By setting the threaded rod 8, the movement of the mounting plate 9 and the rubber pad 10 can be controlled. By setting the mounting plate 9 and the rubber pad 10, the rotation of the rotating rod 4 can be restricted.

[0032] The end of the central support rod 1 near the restraining ring 2 is fixedly connected to a fixed plate 13. The inner wall of the fixed plate 13 is slidably connected to an insertion rod 14, which is slidably connected to the inner wall of the restraining ring 2. The effect achieved by the above components is: by providing the fixed plate 13, the insertion rod 14 can be connected to the central support rod 1. The insertion rod 14, which is slidably connected to the inner wall of the fixed plate 13, can be moved. By providing the insertion rod 14, the central support rod 1 and the restraining ring 2 can be connected. The end of the insertion rod 14 near the support plate 11 is fixedly connected to an arc-shaped block 15. The side of the arc-shaped block 15 near the rotating rod 4 is arc-shaped. The effect achieved by the above components is: by rotating the support plate 11 close to the arc-shaped block 15 through the rotating rod 4, the position of the insertion rod 14 can be moved by moving the arc-shaped block 15. The surface of the insertion rod 14 is covered with a spring 16, and the ends of the spring 16 are respectively fixedly connected to the fixed plate 13 and the arc-shaped block 15.

[0033] Working principle: when producing the heat pipe, first install the constraint ring 2 into the inside of the hollow copper tube, then move the center support rod 1 and insert it into the hollow copper tube, so that the positioning block 3 is stuck in the positioning groove on the constraint ring 2, and then rotate the threaded rod 8 to make it rotate on the inner wall of the arc plate 7, control the mounting plate 9 and the rubber pad 10 to move away from the center support rod 1, release the restriction on the position of the rotating rod 4, rotate the rotating plate 6 to rotate the rotating rod 4, thereby controlling the push plate 11 to rotate close to the arc block 15, the push plate 11 pushes the arc block 15, so that the insertion rod 14 slides on the inner wall of the fixed plate 13, and controls the insertion rod 14 to be stuck in the constraint ring 2. At this time, the push plate 11 moves close to the positioning plate 12, and the threaded rod 8 is rotated to make the mounting plate 9 and the rubber pad 10 move close to the center support rod 1, completing the alignment. After installing the center support rod 1, the copper powder can be filled into the hollow copper tube. By setting the limit ring 5, the position of the rotating rod 4 can be restricted. By setting the spring 16, the position of the insertion rod 14 can be restricted. By setting the constraint ring 2 and the positioning block 3, the position of the center support rod 1 can be restricted after the center support rod 1 is installed inside the hollow copper tube, and the center support rod 1 can be kept consistent with the center of the hollow copper tube as much as possible, thereby ensuring the production quality of the heat pipe as much as possible. By setting the rotating rod 4, the abutment plate 11, the fixing plate 13 and the insertion rod 14, the position of the center support rod 1 can be restricted after the center support rod 1 is installed in the constraint ring 2, and the center support rod 1 can be avoided from moving during the filling of copper powder as much as possible.
