The mouth-sealing method of heat pipe
(1) technical field
The present invention relates to a kind of heat pipe, particularly relate to a kind of mouth-sealing method of heat pipe.
(2) background technology
A kind of manufacture method of existing heat pipe, be that first construction one has an opening port and the metal hollow substrate tube that defines an inner cavity chamber, again with an amount of working fluid after this opening port injects this hollow substrate tube, seal (opening port that promptly seals this hollow substrate tube) after this hollow substrate tube is vacuumized.
Wherein, the above-mentioned mouth-sealing method that should have heat pipe now is to comprise the following step:
(A) as shown in Figure 1, 2, after earlier the opening port 111 of this hollow tube 11 being processed by the facility clamping, make it form the basic kenel of a heat pipe 10.
(B) shown in Fig. 2,3, then utilize facility to cut off, and after cutting off, bestow spot welding (solder joint 12 as shown in Figure 4) and seal airtight effect to reach through the clamping processing flat section position, top 1121 of sealing end 112 (promptly sealing the mouth position) that operation produced.
The opening port 111 of above-mentioned hollow tube 11 in regular turn via clamping distortion, cut off this and seal three kinds of procedure of processings such as end 112 and this opening port 111 of spot welding driving fit after, seal airtight effect though can reach, but, the dealer is as satisfying, desire sealing in the manufacture field at heat pipe, the procedure of processing of seeking more to simplify is to reduce man-hour, manufacturing cost.
(3) summary of the invention
Purpose of the present invention is that a kind of mouth-sealing method of simplifying work flow with the heat pipe that reduces cost is being provided.
The mouth-sealing method of heat pipe of the present invention is applicable to that one has the hollow substrate tube of an opening port, be filled into a working fluid in this hollow substrate tube after, carry out the degasification operation, this mouth-sealing method comprises the following step:
(A) make opening port produce distortion, to seal this opening port through over packing and the post-job hollow substrate tube of degasification; And
(B) with the high energy radiation of the laser light deformation place at the opening port of this hollow substrate tube, and the end segment that can sweep the deformation place of disconnected, this hollow substrate tube of welding simultaneously reaches and seals airtight effect.
For further specifying above-mentioned purpose of the present invention, design feature and effect, the present invention is described in detail below with reference to accompanying drawing.

(5) specific embodiment
For convenience of description, at following embodiment, similar elements is to represent with same numeral.
Shown in Fig. 5,6, one preferred embodiment of the mouth-sealing method of heat pipe of the present invention, be applicable to that one has the hollow substrate tube 20 of an opening port 21, after in this hollow substrate tube 20, being filled into a working fluid (figure does not show), carry out the degasification operation, because of above-mentioned through the post-job hollow substrate tube of over packing and degasification 20 with existing identical, and be not to be key character of the present invention, so no longer describe in detail at this; And mouth-sealing method of the present invention comprises step 30,40.
In step 30, be just to be out of shape, to seal this opening port 21 through opening port 21 generations of over packing and the post-job hollow substrate tube 20 of degasification; In the present embodiment, this opening port 21 can be the flat back of the flat distortion of folder, folder as shown in Figure 7 bending distortion as shown in Figure 6, or three kinds of kenels such as torsional deformation as shown in Figure 8; As shown in Figure 6, when pressing from both sides flat distortion, be the pipe shaft of fixing this hollow substrate tube 20 earlier, utilize flat this opening port 21 of anchor clamps (figure does not show) folder again, reach the flat distortion of folder, in addition, as shown in Figure 7, if opening port 21 bendings that further will be through pressing from both sides flat distortion then can be finished the bending distortion of the flat back of folder; As shown in Figure 8, when carrying out torsional deformation, be the pipe shaft of fixing this hollow substrate tube 20 earlier, utilize rotation type anchor clamps (figure does not show) to reverse this opening port 21 again, reach torsional deformation.
Shown in Fig. 5,6, in step 40, a laser light that provides a laser aid (figure does not show) is radiated at the deformation place 22 of the opening port 21 of this hollow substrate tube 20, the high-energy of this laser light of mat and the end segment that can sweep the deformation place 22 of disconnected, this hollow substrate tube 20 of welding is simultaneously sealed airtight effect to reach.
By this, the mouth-sealing method of heat pipe of the present invention is to comprise: after making opening port 21 distortion, reach with laser light and to sweep two procedure of processings such as deformation place 22 disconnected, this hollow substrate tube 20 of welding, reach and seal airtight effect, its mouth-sealing method that is different from the existing heat pipe shown in Fig. 1 ~ 4 needs via the clamping distortion, cuts off and three kinds of procedure of processings such as spot welding driving fit, not only need use three kinds of machining machine and tools and when taking a lot of work because of processing is complicated, mouth-sealing method of the present invention relatively only need use two kinds of facility, and tool processing is simple and easy and save man-hour, can reduce eventually and seal cost.
Though the present invention describes with reference to current specific embodiment, but those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the present invention, under the situation that does not break away from spirit of the present invention, also can make the variation and the modification of various equivalences, therefore, as long as variation, the modification to the foregoing description all will drop in the scope of claims of the present invention in connotation scope of the present invention.
