Problems solved by technology

[0005] The disadvantage of this structure is that in the process of forming the capillary structure layer 300, capillary particles need to be filled in the tube body 100, how to evenly fill the capillary particles on the inner wall while leaving corresponding steam channels is also a difficult point in processing.
In actual work, partial powder phenomenon often occurs, that is, the capillary particles are unevenly distributed along the inner wall of the tube body, resulting in uneven distribution of the capillary structure layer.
Therefore, it is difficult to further improve the thinness, performance and mass production stability of flat heat pipes

Embodiment Construction

[0033] Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in further detail:

[0034] Such as Figure 4 As shown, a manufacturing method of a heat pipe includes the following steps.

[0035] Step 1 as Figure 4 As shown in (a), the rod body 900 with a circular cross section is inserted into the tube body 100 with a circular cross section, the tube body 900 is pre-flattened, and then capillary particles 390 are filled in the spaces left at both flattened ends.

[0036] Step 2 as Figure 4 As shown in (b), the rod body 900 is pulled out, and the tube body 100 is expanded.

[0037] Step 3 as Figure 4 As shown in (c), mark the position where the capillary particles 390 are filled, apply pressure to the tube body that is filled with the capillary particles 390, and flatten the tube body 100 until they are respectively distributed on the inner wall of the tube body 100 The capillary particles 390 at opposite positions are...

Abstract

The invention provides a manufacturing method of a heat pipe and the heat pipe. The manufacturing method of the heat pipe comprises the following steps of: a pre-flattening step and a step of flattening again, wherein in the pre-flattening step, a rod body is inserted into a pipe body, the pipe body is flattened, then capillary particles are filled into the pipe body, and the rod body is taken out; and in the step of flattening again, the pipe body is flattened further.

Description

technical field [0001] The invention relates to a manufacturing method of a heat pipe and the heat pipe. Background technique [0002] The characteristics of the heat pipe are very suitable for the field of electronic heat dissipation. Its basic working principle is as follows: when one end of the heat pipe is heated, the liquid working fluid inside it is vaporized into steam at the heating end, and the steam quickly transfers heat to other parts of the heat pipe through the steam channel . When the steam reaches the condensing end, it will condense into a liquid and release the latent heat of vaporization. At this time, the liquid working fluid flows back to the heating end through the capillary structure inside the heat pipe. Through the continuous condensation and evaporation cycle of the working fluid, the efficient heat conduction of the heat pipe is realized. Nowadays, the volume of electronic products is getting smaller and smaller, and the integration level of its ...
