Problems solved by technology

[0016] 1) The diameter reduction processing of the end from any sealing end is easy to cause damage to the sealing structure during the processing, resulting in failure of the heat pipe
[0017] 2) End pipe diameter reduction processing from any sealing end, if a longer length needs to be cut, it will take a long time to shrink the pipe to the cutting place, and consume materials
[0018] 3) The diameter of the end is reduced from any sealing end. If a longer length needs to be cut off, the copper tube is prone to bending deformation during the processing, which affects the processing quality.
[0019] 4) The diameter of the pipe is reduced from any sealing end. The longer the pipe shrinking distance, the more copper powder chips will be generated, and it is not easy to get rid of. Copper powder chips remaining in the heat pipe will affect the heat conduction quality

Embodiment Construction

[0042] The technical characteristics of the present invention will be further described in conjunction with the following examples. This example is only a preferred representative example and is not intended to limit the scope of the present invention. The best results will be achieved by referring to the accompanying drawings and in conjunction with the following detailed descriptions. understand.

[0043] First, please refer to Figure 2~2 b, according to the manufacturing method of heat pipe of the present invention, at least comprise the following steps:

[0044] Material preparation step: prepare the empty copper pipe 100 of fixed size (as figure 2 Step 1) of a), the empty copper pipe 100 is usually greater than the length required by the customer.

[0045] Sealing step for the first time: one end 100a of the empty copper tube 100 is sealed, and spot welding is carried out at this sealing end (such as figure 2 Step 2 of a).

[0046] Powder filling step: firstly posi...

Abstract

The invention discloses a making method of heat-conducting, which comprises the following steps: preparing the fixed dimension hollow copper pipe; welding the one end of hollow copper pipe; adding metal powder in the pipe through the other end; heating the copper pipe to form a capillary layer in the pipe; extracting the air in the pipe; injecting the heat-conducting dielectric; closing the other end of pipe; compressing to produce the semi-product pipe; shortening the pipe diameter on the pipe according to the customer request; cutting the semi-product pipe; welding; folding or pressing the pipe according to the need.

Description

technical field [0001] The invention relates to a manufacturing method of a heat pipe, in particular to a method of manufacturing a heat pipe semi-finished product with a fixed size and a consistent specification, and then performing subsequent manufacturing according to the length required by the customer, which can improve production efficiency and greatly shorten the delivery cycle. Background technique [0002] In recent years, with the rapid development of information, communication and optoelectronic industries, electronic products have gradually become more compact and compact. Under the demand of high speed, high frequency and miniaturization, the heat density of electronic components is getting higher and higher, so the heat dissipation Efficiency has become an important factor in determining the stability of electronic products; due to the high-efficiency heat transfer characteristics of heat pipes, it has become one of the heat-conducting components widely used in ...
