Fig. 1A is a front view and fig. 1B is a cross-sectional view of the present invention. As shown, the present invention includes a body 11 (for example, but not limited to, a non-flat heat pipe (for example, a circular heat pipe)) defining a chamber 12 therein, the chamber 12 containing a working fluid (not shown) and a capillary structure 13, wherein the chamber 12 is partitioned into an evaporation portion 121, an insulation portion 122 and a condensation portion 123, and the insulation portion 122 is located between the evaporation portion 121 and the condensation portion 123. The capillary structure 13 extends from the evaporation portion 121 to the condensation portion 123 through the heat insulation portion 122. The working fluid is heated in the evaporation portion 121 to become a gas state, then flows to the condensation portion 123 through the heat insulation portion 122, and then is dissipated from the condensation portion 123 to become a liquid state to return to the evaporation portion 121 by virtue of the capillary force of the capillary structure 13.
The main body 11 has at least one straight section 111, 112 and a corrugated section 113, and this embodiment shows that the two straight sections 111, 112 are respectively located at two sides of the corrugated section 113, and the straight sections 111, 112 respectively correspond to the evaporation portion 121 and the condensation portion 123, and the corrugated section 113 corresponds to the heat insulation portion 122. The corrugated section 113 includes a plurality of corrugations 141 arranged at intervals, which are a plurality of continuous folds or bends to form a concavo-convex staggered or wave crest and wave trough structure on the body 11.
Continuing to refer to FIG. 2A, a schematic partial cross-sectional view of a first embodiment of the capillary portion of the corrugated section 113 of the present invention is shown; fig. 2B is a partially enlarged schematic view of the corrugation 141 of the present invention. As shown in fig. 2A and referring to fig. 1A and fig. 1B, the capillary structure 13 includes a first capillary portion 131 located in the straight sections 111 and 112 and a second capillary portion 132 located in the corrugated section 113, and the first capillary portion 131 is in capillary connection (or contact) with 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 2A.
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 as 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 to fig. 2A again, the present embodiment shows that the plurality of corrugation heights Y1 are different heights, and each corrugation height Y1 is gradually higher from the middle of the corrugation section 113 to both sides of the corrugation section 113. That is, the corrugation height of the corrugation 141 in the middle of the corrugation section 113 is short, and the corrugation height of the corrugation 141 on both sides of the corrugation section 113 becomes gradually high.
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.
Referring to fig. 2C and fig. 2D, a second embodiment of the capillary portion of the corrugated portion 113 according to the present invention is shown in a partial sectional view and enlarged. Although the second capillary portion 132 is shown as a mesh capillary, it is not limited thereto, and in another alternative implementation, the second capillary portion 132 is a braided ribbon (woven) capillary, that is, a braided ribbon shape formed by interweaving and winding a plurality of fiber threads in a strand or bundle manner, so that a solid capillary structure is formed, and the capillary structure has better axial transport capability and deflection resistance capability.
Please refer to fig. 3A, which is a schematic view illustrating the bending angle greater than 90 degrees according to the present invention; FIG. 3B is a schematic cross-sectional view of FIG. 3A of the present invention; fig. 3C is a schematic view of the present invention with a bend angle of approximately 90 degrees. 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.
With continued reference to fig. 4A-4G, various implementations of the corrugated section 113 according to the present invention are illustrated.
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 of the corrugation segment 113 to both sides, 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 spiral line.
Referring to fig. 5A and 5B, the flexible portion of the present invention has other different corrugation characteristics. As shown in the drawing, in another embodiment, the corrugation height Y1 of each corrugation 141 is the same, but the corrugation width X1 is different, for example, the first corrugation 141 and the second corrugation 151 on the inner side of the bend of the body 11 do not interfere with each other when bending from the middle of the corrugation 113 to the two sides of the corrugation 113, and the plurality of corrugation pitches 16 are the same in the drawing, but may be different.
Referring to fig. 6, the main body 11 of the previous embodiments is illustrated as a circular heat pipe, but not limited thereto, the main body 11 may be a flat heat pipe or a temperature equalizing plate, and the main body 11 may be bent at different curvatures of the corrugated sections 113 so as not to interfere with each other. 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.).
According to the present invention, any one of the above-mentioned corrugations 141 has different corrugation characteristics, so that the corrugated section 113 of the body 11 is bent at different curvatures, and the plurality of corrugations 141 do not interfere with each other inside 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.
