Description

Technical Field

[0001] The utility model relates to the technical field of heat pipe fixing jigs, in particular to a heat pipe powder coating fixing jig. Background Art

[0002] The existing heat pipe fixing jig is convenient for fixing irregular heat pipes, but when copper powder is filled inside the irregular heat pipe, since the irregular heat pipe is fixed in the heat pipe fixing jig for easy movement, it is inconvenient to fill the copper powder at the bending part of the irregular heat pipe, resulting in uneven filling of the copper powder inside the irregular heat pipe. The copper powder inside the heat pipe plays a role of heat conduction, and the uneven filling will cause the heat pipe to have areas with poor heat conduction during the heat transfer process, thereby reducing the overall heat dissipation performance. When the heat conduction is uneven, the temperature distribution at different parts of the heat pipe will become uneven, resulting in local overheating or overcooling, affecting the normal operation and stability of the heat pipe. If the copper powder is filled unevenly, thermal stress may be concentrated at specific parts of the irregular heat pipe, increasing the stress and risk of the heat pipe, which may cause the heat pipe to bend, deform or even be damaged.

[0026] The working principle and use process of the utility model are as follows: when it is necessary to add copper powder to the inside of an irregularly shaped heat pipe, the open end of the heat pipe is placed in the fixed cavity 17 in the middle of the heat pipe fixing fixture 1. The fixed cavity 17 is open to facilitate the placement of irregular heat pipes. The first motor 2 is controlled by the controller to work. The first motor 2 drives the first shaft 3 to rotate.

Irregular heat pipes of different sizes can also be fixed to ensure that the irregular heat pipe will not move or loosen during the addition of copper powder, thereby improving the heat dissipation effect and heat transfer efficiency, and the position and posture of the heat pipe can be accurately controlled.

[0027] When the irregular heat pipe is fixed, it is necessary to add copper powder to the irregular heat pipe. When a part of the copper powder needs to be added to the irregular heat pipe, since there is a bend inside the irregular heat pipe, the second motor 11 is controlled by the controller to work, and the second motor 11 drives the second shaft 12 to rotate. The second shaft 12 simultaneously drives one of the rubber fixing blocks 13 to rotate, and the two rubber fixing blocks 13 are squeezed and fixed on the irregular heat pipe. The irregular heat pipe simultaneously drives another rubber fixing block 13, the rotating column 15, and the chuck 16 to rotate in another chuck body 10, changing the position of the irregular heat pipe so that the copper powder inside the irregular heat pipe can flow into the other side of the bend conveniently, which helps to ensure that the copper powder can flow into the irregular heat pipe conveniently. On the other side of the bend inside the heat pipe, by changing the position of the irregular heat pipe, the copper powder inside can flow smoothly, which helps to fill the small gaps and bends of the irregular heat pipe and improve the thermal conductivity and heat conduction efficiency. By causing the copper powder to flow to the other side of the bend, the good contact between the heat pipe and the surrounding environment can be increased, and the heat conduction efficiency can be improved, which helps to improve the heat dissipation effect and avoid overheating of the heat pipe. The two piezoelectric crystals 14 are powered on synchronously, and the two piezoelectric crystals 14 drive the irregular heat pipe to vibrate slightly. The slight vibration can help the copper powder flow more smoothly inside the heat pipe. When there are bends or irregular structures in the heat pipe, the vibration can help the copper powder overcome resistance, better fill the internal gaps and bends, and improve thermal conductivity.
