As shown in fig. 2A and referring to fig. 1A and fig. 1B, the capillary structure 13 includes a first capillary portion 131 located on the straight sections 111 and 112 and a second capillary portion 132 located on the corrugated section 113, and the first capillary portion 131 is connected (or connected) to the second capillary portion 132. By capillary bonding, it is meant that the capillary forces of the first capillary portion 13 and the second capillary portion 132 can be transmitted or communicated with each other, and can be accomplished by bonding means such as bonding, butt bonding or welding.
The second capillary portion 132 has two ends 1321, 1322 extending from the corrugated section 113 to the straight sections 111, 112, respectively. That is, the first capillary portion 131 is disposed in the evaporation portion 121 and the condensation portion 123, the second capillary portion 132 is disposed in the heat insulation portion 122, both ends 1321, 1322 of the second capillary portion 132 partially extend the evaporation portion 121 and the condensation portion 123, and the length of the second capillary portion 132 in the X direction is longer than that of the corrugated portion 113 in the X direction.
The first capillary portion 131 is, for example but not limited to, a sintered capillary or a woven capillary or a grooved capillary or a fiber capillary, and the second capillary portion 132 is a woven capillary that matches the deflection requirements of the corrugated section 113. In this embodiment, the sintering capillary is, for example, metal powder sintering, and the weaving capillary is, for example, a mesh capillary (i.e., a mesh body woven by warps and wefts) shown in fig. 1B and 2 a.
The plurality of corrugations 141 have a corrugation pitch 16 therebetween, and in this embodiment, the corrugation pitches 16 are equal, so that adjacent corrugations 141 are disposed at equal intervals.
Furthermore, as shown in fig. 2B, each corrugation 141 has a corrugation bottom 1411 and a corrugation top 1412, the corrugation bottom 1411 is adjacent to an outer surface 110 of the body 11 (i.e. at the same level with the outer surface 110, or at a level higher/lower than the outer surface 110), and a corrugation top 1412 protrudes from the outer surface 110 of the body 11. And a corrugation height Y1 is defined between the corrugation bottom 1411 and the corrugation top 1412.

Referring again to FIG. 2B, each corrugation 141 has a corrugation left-most side 1413 and a corrugation right-most side 1414, and a corrugation width X1 is defined between the corrugation left-most side 1413 and the corrugation right-most side 1414. The present embodiment shows that the corrugation thickness X1 of each corrugation 141 is the same thickness.

As shown, when the body 11 is bent by the plurality of corrugations 141 of the corrugated section 113 by more than 90 degrees, for example, 180 degrees (as shown in fig. 3A and 3B) or substantially equal to 90 degrees (as shown in fig. 3C), the plurality of corrugations 141 on the bent inner side of the body 11 do not interfere with each other because the corrugation 141 located in the middle of the corrugated section 113 is shorter than the corrugation height X1 of the corrugations 141 on both sides of the corrugated section 113. The problem that the existing bending angle is limited is solved through the structure of the scheme.
Fig. 4A to fig. 4G are schematic diagrams of various implementations of the bellows 113 according to the present invention.
In other embodiments, as shown in fig. 4A and 4B, the corrugation height Y1 of the plurality of corrugations 141 may gradually increase from the left side to the right side of the corrugated portion 113, or gradually increase from the right side to the left side of the corrugated portion 113.
Referring to fig. 4C and 4D, although the corrugation pitches 16 between the plurality of corrugations 141 are equal as shown above. However, in another embodiment, the corrugation pitch 16 between the plurality of corrugations 141 is not equal, for example, the corrugation pitch 16 between the plurality of corrugations 141 is changed from a middle of the corrugated section 113 to a side thereof from a short length (fig. 4C) or a long length (fig. 4D).
As shown in fig. 4E, the above embodiment shows that the plurality of corrugation widths X1 are the same. However, in another embodiment, the corrugation width X1 is different, for example, the corrugation width X1 is narrower and wider from the middle to both sides of the corrugation segment 113, so that the first corrugation 141 and the second corrugation 151 do not interfere with each other when being bent.
As further shown in fig. 4G, in another alternative implementation, the plurality of corrugations 141 of the corrugated section 113 are alternately spaced apart by a high corrugation height Y1 and a low corrugation height Y1.
It should be noted that in the figures of the above embodiments, the plurality of corrugations 141 are represented by annular corrugations, that is, the corrugations 141 surround the body 11 in a closed annular shape. However, in an alternative embodiment, as shown in fig. 4E, the plurality of corrugations 141 are spiral corrugations, that is, the plurality of corrugations 141 are spirally arranged around the body 11, and a helix angle θ is formed between two adjacent corrugations 141, and all of the plurality of corrugations 141 can be connected by a helix.
With reference to fig. 5A and 5B, the flexible portion of the present invention has different corrugation characteristics. As shown, in another embodiment, the corrugation height Y1 of each corrugation 141 is the same, but the corrugation width X1 is different, for example, the corrugation width is narrowed and widened from the middle of the corrugation section 113 to the two sides of the corrugation section 113, so that the first corrugation 141 and the second corrugation 151 on the inner side of the bending of the body 11 do not interfere with each other when being bent, and the plurality of corrugation pitches 16 are shown as the same in this embodiment, but may be different.
Referring to fig. 6, the main body 11 of the previous embodiments is illustrated as a circular heat pipe, but the present invention is not limited thereto, and the main body 11 may be a flat heat pipe or a temperature-equalizing plate, so that the main body 11 can be bent at different curvatures of the corrugated sections 113 without interference between the plurality of corrugations 141. The body 11 is made of a metal material, such as a single metal (including aluminum, copper, stainless steel, titanium, etc.) or a composite metal (alloy) (including an aluminum-magnesium alloy, a copper-nickel alloy, an aluminum-copper alloy, a titanium alloy, etc.).
The present invention relies on the difference of any corrugation feature of the corrugations 141, so that the corrugation segment 113 of the body 11 is bent at different curvatures, and the plurality of corrugations 141 do not interfere with each other at the inner side of the bending.
The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
