Abstract
A method for producing a heat pipe comprises steps of preparing a pipe body and a mandrel; inserting the mandrel into the pipe body, enabling the bottom end of the pipe body to be in a sealing state and enabling the mandrel and the inner wall of the pipe body to form at least one groove; placing copper powder the surface of which is attached to an adhesive agent into the groove from the top end of the pipe body; extracting the mandrel from the pipe body and maintaining the copper powder shape which exists when the copper powder is placed in the groove by the aid of the adhesive effect of the adhesive agent; heating the pipe body, sintering the copper powder inside the pipe body and further forming a long capillary material; sealing one end of the pipe body, performing a vacuum-pumping process and injecting a working solution; and sealing the other end of the pipe body.
Description
Technical field
The present invention is relevant with the manufacturing technology of heat pipe, refers to that particularly the copper powder that uses the surface to attach adhesive agent fills out behind the powder a kind of heat control making method of sintering again.
Background technology
Existing heat pipe, its inner capillary materials is to use the copper powder sintering to form mostly.
And the manufacturing approach of present heat pipe is the copper powder that needs sintering to capillary materials, normally penetrates in the body of heat pipe with a plug during fabrication, and with end sealing, copper powder is poured into again, and copper powder is clogged between plug and body; Again body is inserted together with plug, copper powder and carry out sintering in the heater, with after this plug extraction and inserting suitable liquid and gas, seal this heat pipe at last, promptly accomplish the manufacturing of heat pipe.
And flat heat pipe promptly is that above-mentioned heat pipe is flattened and forms.
TOHKEMY 2009-170228 patent case (the early stage publication number of TaiWan, China is 2011-04203), its disclosed the local capillary structure body of flat heat pipe set inside and and have the technology at acute angle position between the tube wall.Yet; This case is owing to be to insert the copper powder that does not attach adhesive agent when filling out powder; Therefore when sintering, must heat body together with plug; The distortion of just can not scattering of copper powder in body, but plug is easy to generate distortion and can't uses, the plug that promptly must more renew at this moment after heating for several times.The consumption that this shows plug has also constituted a part of cost of making at existing heat pipe, has caused the increase of manufacturing cost.
Summary of the invention
Main purpose of the present invention is to provide a kind of heat control making method; Its copper powder that can use the surface to attach adhesive agent is inserted body; And then again this body is heated with the inner copper powder of sintering after making plug can extract body earlier out; Be not heated and damage with the protection plug, and then save manufacturing cost.
In order to reach aforementioned purpose, the manufacturing approach according to a kind of heat pipe provided by the present invention includes the following step: a) purchase a body and a plug; B) this plug is inserted this body, and make this body bottom constitute closed state, this plug and this inboard wall of tube body form at least one groove; C) copper powder that the surface is attached adhesive agent is inserted in this at least one groove by the top of this body; D) this plug is extracted this body, the shape when this copper powder is kept it by the sticking together effect of this adhesive agent and is located in this at least one groove; E) to this body heating, make the copper powder sintering in this body, and then form microscler capillary materials; F), and inject working solution with vacuumizing behind this body one end closure; And g) other end with this body seals.Therefore, the copper powder that can use the surface to attach adhesive agent is inserted body, and then this body is heated with the inner copper powder of sintering after making plug can extract body earlier out again, and the protection plug is not heated and damages, thereby saves manufacturing cost.
