Description

Technical Field

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

[0002] At present, the manufacturing of heat pipes requires two sealings. The end with a notch is the sealing end, and the end without a notch is the closed end. Currently, the sealing method for the sealing end is U-shaped sealing. The disadvantage is that there is a notch at the sealing position. Due to the disadvantage of U-shaped sealing, before bending, the direction of the notch needs to be adjusted and fixed for each heat pipe so that the appearance of the bent heat pipes can be consistent. Summary of the Utility Model

[0003] In view of the above defects existing in the prior art, the utility model provides a heat pipe sealing structure to solve the problem that the direction of the notch needs to be adjusted and fixed for the heat pipe before bending to ensure that the appearance of the bent heat pipe is consistent.

[0004] The utility model is realized by adopting the following technical solutions:

[0005] A heat pipe sealing structure includes a pipe body. One end of the pipe body is a closed end, and the other end is a sealing end. The sealing end is a hemispherical head sealing structure with a solid interior, and the axis of the hemispherical head sealing structure coincides with the axis of the pipe body.

[0006] Further, the sealing end includes a necking section and a sealing section. The sealing section is a solid cylindrical end connected to a hemispherical head structure. One end of the necking section is connected to the pipe body, and the other end of the necking section is connected to one end of the cylinder. The axis of the cylinder coincides with the axis of the pipe body, and the outer diameter of the cylinder is smaller than the outer diameter of the pipe body.

[0007] Further, the length of the cylinder is 8 mm.

[0008] Further, the necking section is a solid conical structure.

[0009] Further, the diameter of the conical structure gradually decreases in the direction towards the sealing section.

[0010] Further, the length of the necking section is 10 mm.

[0011] Further, the pipe body is a cylindrical structure.

[0012] Further, the pipe body is a solid structure.

[0013] Compared with the prior art, the beneficial effects of the utility model at least include:

[0014] In the present utility model, the sealing end of the tube body is set as a hemispherical head sealing structure with a solid interior. The hemispherical sealing structure has no notch, so there is no need to consider the notch direction in subsequent processes, eliminating the two processes of adjusting and fixing the notch direction before bending, improving production efficiency, and ensuring that the appearance of the heat pipe after bending is more consistent.
