The specific embodiment
In order further to understand feature of the present invention and technology contents, see also following about detailed description of the present invention and accompanying drawing, yet accompanying drawing with describe in detail only provide with reference to the usefulness of explanation, be not for limiting the present invention.
The invention provides a kind of capillary texture forming method and finished product thereof of tabular heat pipe, its by metal powder sintered on wire netting to form laminar capillary structure, and then go for the tabular heat pipe of slimming, can be simultaneously as the capillary structure in the tabular heat pipe and supporting construction.See also the step S1 of Fig. 1 and cooperate shown in Figure 2: at first, prepare a wire netting 1 earlier; Can to be that single or multiple lift is stacked form wire netting 1, and each layer all form with the interleaving mode braiding by many wire 10, and the present invention for embodiment in, prepared wire netting 1 is individual layer.
Then, shown in the step S2 and step S3 of Fig. 1, these two steps can change sequencing; And the present invention for embodiment with step S2 formerly and step S3 after be example.So see also Fig. 3 and shown in Figure 4: after above-mentioned wire netting 1 infiltrates metal dust 2, infiltration can be had the wire netting 1 of metal dust 2 to carry out sintering; And owing to wire netting 1 is formed by many wire 10 braidings, so have the gap in 10 in each wire, can infiltrate for metal dust 2, and after to be sintered the finishing, metal dust 2 can be bonded on the wire netting 1, and wire netting 1 also can have the effect of typing because being bonded with metal dust 2 on it, but still can keep its original lamellar form.Afterwards, again on wire netting 1 with methods such as cutting, compacting or punching out and make the position that is recess, or further constitute as one or more hole 11(of Openworks shape namely as shown in Figure 5) etc., with the gas channel that the circulation as the working fluid after the vaporization in the heat pipe time is passed through, so can finish one applicable to the capillary structure in the tabular heat pipe.
Moreover, above-mentioned steps S3 also can have precedence over step S2 and implement earlier, namely after having prepared described wire netting 1, i.e. first punching out hollow-out parts position on wire netting 1, the wire netting of finishing in punching out 1 infiltrates metal dust 2 again, do not clogged by metal dust 2 as long as keep the hollow out position, then carry out sintering work, can obtain as above-mentioned applicable to the capillary structure in the tabular heat pipe so equally.
Accordingly, as shown in Figure 5, when above-mentioned wire netting 1 by metal dust 2 sintering thereon after, can form laminar capillary structure and be convenient to insert in the body 3 of a tabular heat pipe; Wherein, be hollow form in the body 3 and form an accommodation space 30 that is the finedraw shape, insert in it for above-mentioned wire netting 1 and be affixed on accommodation space 30 inwalls (namely as shown in Figure 6) to support.Body 3 can be by after the pull moulding, again via being crushed to flat, and the one end can carry out tube sealing earlier and form a blind end 31, the other end and then keep the opening shape earlier and insert for above-mentioned wire netting 1, makes be used to carrying out as the sealing end 32(of operations such as degasification namely as shown in Figure 7 again); And the present invention for embodiment in, described sealing end 32 can comprise a draw portion 320, that is formed by body 30 convergents be formed at draw portion 320 ends except gas port 321 and fill out be encapsulated in described except the mouth-sealed portion 322 on the gas port 321, and before not carrying out operations such as degasification as yet, except gas port 321 is still kept its opening shape and is not sealed with mouth-sealed portion 322, in order to carry out operation such as degasification.
In addition, as shown in Figure 8, be the schematic perspective view of the made tabular heat pipe of another embodiment of the present invention; Wherein, above-mentioned wire netting 1 is when carrying out the technology at punching out depression position, can make also that described depression position is one or more holes 11 that are strip and hollow out, and each hole 11 extends to its sealing end 32 places by nearly its blind end 31 places in the body 30, to communicate with sealing end 32.So, tabular heat pipe is when carrying out the degasification operation, above-mentioned wire netting 1 can not only provide enough support strength to avoid outside body 3 depressions, hole 11 that simultaneously can be by being strip is as gas channel, not concretive gas can be discharged towards sealing end 32 along the hole 11 of strip during for degasification, further to reach the purpose of complete degasification.
By above-mentioned contexture, can obtain capillary texture forming method and the finished product thereof of the tabular heat pipe of the present invention.
The above is preferred embodiment of the present invention only, is not in order to limiting claim of the present invention, so the equivalence of using patent spirit of the present invention to do such as changes and modifies etc., all should in like manner be included in the scope of patent protection of the present invention.
