The specific embodiment
Known cylindric heat pipe fails to be positioned at the heat pipe centre because of process deviation causes the in uneven thickness and cylindrical hole of the sinter layer 14 of heat pipe, so that the usefulness of heat pipe and quality descend, its main cause is when carrying out sintering process, center bar 12 is not to be positioned at copper pipe 10 centers, as shown in Figure 4, and cause the deviation of sinter layer 12 and cylindrical hole, as shown in Figure 5.
Be not positioned at the copper pipe center for solving cylindric heat pipe because of employed center bar in the manufacture process, and cause sinter layer skewness in the prepared heat pipe, cause problems such as heat pipe heat conduction efficiency reduction, with reference to shown in Figure 6, the solution that the present invention proposes is in processing copper pipe 20 processes, add organic sticker with metal powder and make the identical projection of several thickness 24 in advance, again this projection 24 is affixed to center bar 22 surfaces, when making center bar 22 insert in the copper pipe 20, can utilize the projection 24 of this pre-designed height, slight contact copper pipe 20 inwalls, and then make center bar 22 can be positioned copper pipe 20 centres, when carrying out the high temperature sintering processing procedure, this projection 24 can come off from center bar 22 surfaces then, and the sinter layer 26 that sinters into copper pipe 20 inwalls forms one, after extracting center bar 22 out, copper pipe 20 inwalls form a uniform sinter layer 26, and stay a cylindrical hole 28 in copper pipe 20 positive centers, as shown in Figure 7.Next continue to finish the successive process of heat pipe,, after again these copper pipe 20 internal gas being extracted out, seal this copper pipe 20 openends, just can obtain heat pipe finished product one of fine qualities, that usefulness does not give a discount in this steel pipe 20 inner fluids that inject.
Above-mentionedly metal powder is added the projection that organic sticker makes be pasted on the center bar surface, imitate bright for obtaining preferred positioning, projection preferably is pasted on the surface of center bar different level, and the number of projection preferably can accurately be positioned at the copper pipe center position in the hope of center bar more than three.And metal powder is normally based on easy heat-conducting metal powder such as copper powder or aluminium powder.
Can determine the orientable heat pipe manufacture method that the present invention proposes and be pre-formed metal powder to add the heat pipe fixture of the projection of organic sticker by top explanation in the center bar surface, really has the effect of avoiding heat pipe usefulness to be descended because of process deviation, and the method that the present invention proposes implements quite easy, and can directly cooperate with other processing procedure of script heat pipe, must not revise other processing procedure and relevant device, sizable effect be arranged for the quality control of heat pipe product.
The above is preferred embodiment of the present invention only, is not to be used for limiting practical range of the present invention.So be that all equalizations of doing according to the described shape of the present patent application claim, structure, feature and spirit change or modification, all should be included in the claim of the present invention.
