Abstract
In the invention, at the end port of the heat-pipe body is formed a pipe-contracting part with a conical surface, which is press-sealed. In the pressed sealing process, the location of the heat-pipe body near the conical surface produces deformation. After the soldering and sealing of the edge of the pinning part, the deformed location of the heat-pipe body near the pipe-contracting part is shaped to shape as the same as one of the outer wall of the heat-pipe body.
Description
Technical field
The present invention relates to a kind of heat pipe pressing sealing method, but relate in particular to a kind of pressing sealing method of length of shortening heat channel closure end.
Background technology
Shown in Figure 1 is the enclosuring structure of the heat pipe 1a of prior art.The enclosuring structure of prior art heat pipe 1a shown in Figure 1 is after at first the nose end 10a of heat pipe 1a being dwindled into the 100a of draw portion by draw preparation method, utilize the end of the tube sealing clamp die tightening tube 100a of portion to flatten district 101a again to constitute, then, (figure slightly) welded in upper end at this flattening district 101a, thereby the nose end 10a of this heat pipe 1a is sealed.
In the enclosuring structure of the heat pipe 1a of above-mentioned prior art, the main purpose that its nose end 10a dwindles into the 100a of draw portion is to make the volume and the area in the enclosuring structure zone of nose end 10a at first to be reduced, so that carry out welding processing.Yet, though dwindling the back, the nose end 10a of heat pipe 1a helps welding processing, but caused the generation of the invalid end of heat pipe 1a, especially when heat pipe 1a is applied on the occasion that is connected in series radiating fin, the nose end 10a of heat pipe 1a not only can't be connected in series outside the fin because of the caliber that dwindles, and more fins group is outer to take up room because of this nose end 10a must give prominence to.
Therefore, need a kind of heat pipe pressing sealing method that overcomes the defective that exists in the above-mentioned prior art.
Summary of the invention
Main purpose of the present invention is to overcome above shortcomings in the prior art, and then a kind of heat pipe pressing sealing method is provided.Utilize described method solve prior art not enough the time, but the length of shortening heat channel closure end not only and can also increase the quantity that heat pipe wears radiating fin, or reduces heat pipe and protrudes in outer shared space, invalid end.
In order to reach above-mentioned purpose, a kind of heat pipe pressing sealing method that the present invention system provides comprises: a) form the draw portion with conical surface on the port of tube body of heat pipe; B) described draw portion is carried out pressing sealing, and in the process of pressing, make the position of approaching the conical surface of tube body of heat pipe produce distortion; C) utilize the edge of this draw portion of welded seal; D) deformation place that approaches this draw portion with tube body of heat pipe is shaped as the shape that conforms to the tube wall shape.

The specific embodiment
Below with reference to accompanying drawings the present invention is described in detail, wherein institute's drawings attached only provides reference and explanation usefulness, is not to be used for the present invention is limited.
Be illustrated in figure 2 as the three-dimensional appearance schematic diagram after heat pipe of the present invention is shaped.The invention provides a kind of heat pipe pressing sealing method, it can shorten the length of the sealing end 10 of heat pipe 1.Just, after the sealing end of heat pipe 1 10 was sealed, its sealing end 10 became the invalid end of this heat pipe 1, therefore need will this invalid end length reduction.
Below heat pipe pressing sealing method of the present invention will be described.
Shown in Figure 3, at first, on the port of the body 11 of heat pipe 1, form and have the draw portion 10 of taper seat 100, and shorten the length of draw portion 10 as far as possible, and need not to consider after draw portion 10 is by pressing, whether can influence the problem that body 11 is out of shape.
As shown in Figure 4 and Figure 5, the draw portion 10 of body 11 is arranged at pressing in the mould 2, carry out pressing sealing with taper seat 100, thereby in draw portion 10, form the flattening tube wall 101 that madial wall connects airtight this draw portion 10.In the process of pressing, owing to pressing mould 2 to force on the taper seat 100 of draw portion 10,, form the planform that extends out, as shown in Figure 6 so will produce distortion because of the operation of pressing sealing at the position that body 11 approaches taper seat 100.
So far, can weld the edge of draw portion 10, flatten tube wall 101 upper ends formation Welding Structure 102 like this, as shown in Figure 7 with its sealing.
To utilize shaping mould 3 to operate below, as shown in Figure 8.Shaping mould 3 can comprise the sizing die 30,31 that inwardly is concave arc.After sizing die 30,31 merged, its inner concave arc surface constituted the body 11 outer wall shapes of heat pipe 1 just.The position that body 11 is out of shape because of the operation of pressing sealing is arranged in the shaping mould 3, makes the position of body 11 distortion be shaped as original shape with the action by shaping mould 3 matched moulds, like this, has just obtained the moulding of heat pipe 1 as shown in Figure 2.In an embodiment of the present invention, body 11 is the pipe shape, and therefore, the shape that each sizing die inner concave arc surface of shaping mould 3 is constituted is the circle that conforms to body 11 external diameters.
Like this, just obtained heat pipe pressing sealing method of the present invention by above-mentioned contexture.
Therefore, can shorten the length of the sealing end of heat pipe 1 by heat pipe pressing sealing method of the present invention.Under the situation of equal length,, therefore compare to have longer effective length with the heat pipe of prior art because of the length of the sealing end of heat pipe 1 of the present invention can obtain reduction.Simultaneously, also can increase the quantity that wears radiating fin, or minimizing heat pipe 1 protrudes in outer shared space, invalid end.
In sum, the present invention really can reach the application target of expection, and solves the defective that exists in the prior art.
The above is a preferred implementation of the present invention only, and is not the qualification to protection domain of the present invention.
Therefore all do variations such as equivalence techniques, means to the content in specification of the present invention and the accompanying drawing, all are contained in the scope of the present invention.
