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.
As shown in Figure 2 be three-dimensional appearance schematic diagram of the present invention.The invention provides a kind of heat pipe pressing sealing method and structure thereof.Enclosuring structure of the present invention forms on the sealing end of heat pipe 1, and with so that heat pipe 1 inside is sealing state, so that the working fluid of heat pipe 1 (working fluid) can change mutually, thereby the function of guaranteeing heat pipe 1 is able to normal realization.Simultaneously, the sealing end of heat pipe 1 still can make radiating fin 4 (as shown in Figure 9) serial connection thereon after sealing.
When above-mentioned enclosuring structure forms, at first the sealing end of heat pipe 1 is being pressed and connecting airtight, further, its extruding forms again by being mediated.Further specify it below and manufacture process.
At first, on the sealing end of the body 10 of heat pipe 1, form and have the draw portion 11 of taper seat 110, and shorten the length of draw portion 11 as far as possible, and need not to consider after draw portion 11 is by pressing, whether can influence the problem that body 10 is out of shape, as shown in Figure 3.
As shown in Figure 4 and Figure 5, the draw portion 11 of body 10 is arranged at pressing in the mould 2, carry out the operation of pressing sealing with taper seat 110 to draw portion 11, thereby in draw portion 11, form the flattening tube wall 111 that madial wall connects airtight, and the deformation place that makes draw portion 11 after pressing exceeds the outer wall of the body 10 of heat pipe 1, the position of approaching taper seat 110 that makes body 10 simultaneously produces distortion because of the operation of pressing sealing, forms the planform that extends out, as shown in Figure 6.
Now, the edge of draw portion 11 is welded with its sealing, and then form Welding Structure 112 in the upper end of flattening tube wall 111.As shown in Figure 7.
