The specific embodiment
See also Fig. 2, Fig. 3 and Fig. 4, be respectively schematic flow sheet () and (two) of the preceding schematic perspective view of heat pipe sealing of the present invention, heat pipe sealing manufacture method.The invention provides a kind of heat pipe enclosuring structure and manufacture method thereof of tube without reducing; At first, on manufacture method, as shown in Figures 2 and 3, preparation one has the heat pipe 1 of openend 10, and a pressing mold of being formed by three pressing blocks 2 (or more pressing block 2) at least (figure slightly), this pressing mold (figure is slightly) mainly can make pressing block 2 be moved to the location and impose certain strength of pushing to the center, and each pressing block 2 front end all has the stitching surface 20 that an angle α is constituted, the summation of these angles α is essentially 360 °, and each angle α can be and equates or unequal.
As shown in Figure 4, the openend 10 of this heat pipe 1 is placed three pressing block 2 centers of pressing mold (figure slightly), so that these pressing blocks 2 are after the center displacement, openend 10 tubular axis centers to this heat pipe 1 are pushed, the tube wall 11 that makes this openend 10 is depressed deformation along with the extruding of these pressing blocks 2, until the predetermined leak rate air-tightness of the closely connected each other formation in tube wall 11 inboards of this openend 10, can between each pressing block 2, form a driving fit intermediate plate 12 respectively, constitute the enclosuring structure (promptly as shown in Figure 6) of this heat pipe 1 thus.
As shown in Figure 4, for improving the air-tightness of this heat pipe 1 enclosuring structure, also can further on these driving fit intermediate plates 12, carry out welding operation, forming weld part (figure slightly), and so-called welding operation is meant that developing back formed connecting airtight mutually in tube wall 11 inboards carries out hard solder (brazing), soft soldering (soldering) or direct welding modes such as (welding) on the seam 13; And, also can be behind each pressing block 2 extruding tube wall 11, stitching surface 20 is carried out airtight 15 (as shown in Figure 6) with means of spot welds (spot welding) or ultrasonic fusing modes such as (ultrasonicwelding), and make, and connect airtight the enclosuring structure that seam 13 places do not have crator, salient point etc. by airtight 15 formation airtight construction of tube wall after the pressing 11.
In addition, as shown in Figure 5, be different from and above-mentionedly connect with welding manner, also can be before this heat pipe 1 seals, the mouth of pipe 111 (as shown in Figure 2) that makes its inner capillary structure 14 extend to this openend 10 is located, after tube wall 11 is by above-mentioned manufacture method pressing, when pressing is developed each other in these tube wall 11 inboards, capillary structure because of tube wall 11 extrusion conquassation and filling in 12 of driving fit intermediate plates, so that further air-tightness to be provided.
What deserves to be mentioned is, also can utilize array pressing mold (figure slightly) respectively along the length direction setting of a heat pipe 1 by above-mentioned manufacture method, and after these pressing molds (figure slightly) push, promptly block and seal, to form several short heat pipe finished products.
Therefore, by above-mentioned mode of operation, can obtain the heat pipe sealing manufacture method of tube without reducing of the present invention.
See also Fig. 6, be the schematic perspective view behind the heat pipe sealing of the present invention; The heat pipe enclosuring structure of a kind of tube without reducing provided by the present invention is on the openend 10 that is positioned at this heat pipe 1 (please be corresponding shown in Figure 2), and can be made and comprise three driving fit intermediate plates 12 at least by aforesaid manufacture method; As previously mentioned, each driving fit intermediate plate 12 is the tube walls 11 as this openend 10, extruding because of pressing block 20, form and cave inward to its tubular axis center with the part respectively, and tube wall 11 inboards of this openend 10 are closely connected each other and engage to form airtightly, and then constitute the enclosuring structure of this heat pipe 1.
See also Fig. 7 again, each driving fit intermediate plate 12 forms one airtight 15 respectively on its both sides, and protruding, groove 16 can be set on these airtight 15, so as to the air-tightness that increases flow resistance and improve this heat pipe 1 enclosuring structure.
And, right angle, outer end after also these driving fit intermediate plates 12 can being sealed 121 places parts bending and form kink (figure is slightly), reducing its size, and then the assembling that helps this heat pipe 1 is used or is convenient to operations such as it further welds.
Therefore, by above-mentioned structure, can obtain the heat pipe enclosuring structure of tube without reducing of the present invention.
Therefore, the heat pipe enclosuring structure of tube without reducing of the present invention and manufacture method thereof, must not shrink the mouth of pipe in traditional draw mode again, make the tube wall of heat pipe with fashion of extrusion inboard to engage formation airtight because of closely connected each other and change, and then reach the purpose of heat pipe sealing, solve the cost height of traditional draw mode simultaneously, procedure is many, cause defectives such as fraction defective raising than long and the wayward institute of size man-hour, and simultaneously can be with finished product blocks into several different lengths according to the manufacture method of the present invention heat pipe of making of heat pipe, and method of the prior art does not have this function fully, and in case be made as finished product, its dimensions length all can't change because of the draw, so SC service ceiling system is more.
In sum, the present invention can realize the application target of expecting, and addresses the deficiencies of the prior art, because of having novelty and progressive, meet the application for a patent for invention important document fully again, the spy files an application according to Patent Law, would like to ask sifting and granted patent, to ensure inventor's right.
Above detailed description of the present invention does not limit the present invention, and those skilled in the art can make various changes and distortion according to the present invention, only otherwise break away from spirit of the present invention, all should belong to scope of the present invention.
