DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Please refer to FIGS. 1, 2 and 3. The multi-angle adjustable and transformable heat pipe 1 of the present invention includes a sealed case body 11. The sealed case body 11 can have a circular configuration, a D-shaped configuration or a flat-plate configuration. In this embodiment, the sealed case body 11 is in the form of a flat-plate heat pipe for illustration purposes. The sealed case body 11 has a chamber 12. A working fluid (such as pure water) is filled in the chamber 12. At least one capillary structure 13 is disposed on an inner wall of the chamber 12. The capillary structure 13 is selected from a group consisting of sintered body, channels, mesh body, fiber, braid body and any combination thereof. The sealed case body 11 has a front section 111, a transformable flexible middle section 113 and a rear section 112. The middle section 113 is positioned between the front section 111 and the rear section 112 in connection therewith. The middle section 113 is composed of multiple support sections 1131 and multiple knot sections 1132. The support sections 1131 and the knot sections 1132 are alternately arranged along a lengthwise direction of the middle section 113. In this embodiment, two sides of each knot section 1132 are respectively connected with adjacent support sections 1131, whereby the support sections 1131 and the knot sections 1132 together form a multi-knot structure.

[0017] The support sections 1131 can be adjusted by the same angle or different angles via the knot sections 1132. That is, the support section 1131 between each two knot sections 1132 is angularly adjusted with the knot sections 1132 serving as fulcrums. In addition, the junction between each knot section 1132 and the adjacent support section 1131 is a contact interference position. Accordingly, when the support section 1131 is angularly adjusted, the adjacent knot section 1132 will contact and interfere with the support section 1131 so as to restrict the move and adjustment of the support section 1131 within an angle range (such as one degree~89 degrees). Moreover, after the support section 1131 is adjusted by an angle, the knot section 1132 serves to locate the support section 1131 in the angular position. In addition, each two knot sections 1132 can provide an angular transformation or two different angular transformations. As shown in FIG. 3, one of each two adjacent knot sections 1132 and the two support sections 1131 in connection and adjacency to the knot section 1132 contain an angle X1, which is different from an angle X2 contained between the other knot section 1132 and the two support sections 1131 in connection and adjacency to the knot section 1132. Therefore, by means of the multiple knot sections 1132, many angular transformations can be provided so that the heat pipe 1 can be multi-angle adjusted and located and transformed into various configurations such as multiple U-shaped, N-shaped or otherwise shaped configurations. However, in practice, the angle X1 contained between one of each two adjacent knot sections 1132 and the two support sections 1131 in connection and adjacency to the knot section 1132 can be alternatively equal to the angle X2 contained between the other knot section 1132 and the two support sections 1131 in connection and adjacency to the knot section 1132. For example, the angle X1 and the angle X2 can be both zero degree. In this case, the middle section 113 is stretched into a horizontal state (as shown in FIG. 2). Each knot section 1132 also provides an effect to enhance the structural strength of the middle section 113.

[0018] Furthermore, in this embodiment, the length 141 of each support section 1131 along the lengthwise direction 151 of the sealed case body 11 is larger than the length 142 of each adjacent knot section 1132 along the lengthwise direction 151 of the sealed case body 11. Accordingly, the support section 1131 can be adjusted by larger angle. The lengthwise direction 151 of the sealed case body 11 means a direction from the front section 111 to the rear section 112. The widthwise direction 152 of the sealed case body 11 means a direction from a left side to a right side of the sealed case body 11. In a modified embodiment, the length 142 of each knot section 1132 along the lengthwise direction 151 of the sealed case body 11 is equal to the length 141 of the adjacent support section 1131 along the lengthwise direction 151 of the sealed case body 11. Alternatively, the length 142 of most knot sections 1132 along the lengthwise direction 151 of the sealed case body 11 is smaller than the length 141 of the adjacent support section 1131 along the lengthwise direction 151 of the sealed case body 11, while the length 142 of the rest knot sections 1132 along the lengthwise direction 151 of the sealed case body 11 is equal to the length 141 of the adjacent support section 1131 along the lengthwise direction 151 of the sealed case body 11. The longer knot sections 1132 and the shorter knot sections 1132 cooperate with each other, whereby the length of the knot sections 1132 of the middle section 113 can be adjusted and changed so as to change the angle adjustment range of the support sections 1131.

[0019] Furthermore, it should be noted that in this embodiment, the chamber 12 of the sealed case body has an evaporator section 121, an adiabatic section 122 and a condenser section 123. The evaporator section 121 and the condenser section 123 are respectively positioned in the front section 111 and the rear section 112 of the sealed case body 11, while the adiabatic section 122 is positioned in the middle section 113 between the evaporator section 121 and the condenser section 123. The capillary structure 13 has multiple first capillary structures 131 and a second capillary structure 132. The first capillary structures 131 and/or the second capillary structure 132 are selected from a group consisting of sintered body, channels, mesh body, fiber, braid body and any combination thereof. The first capillary structures 131 are respectively disposed on inner walls of the evaporator section 121 and the condenser section 123. In addition, the first capillary structures 131 of the evaporator section 121 and the condenser section 123 are selectively the same capillary structures or different capillary structures. The second capillary structure 132 is disposed on inner walls of the support sections 1131 and the knot sections 1132 of the adiabatic section 122. The first capillary structures 131 and the second capillary structure 132 are in horizontal connection (mating) with each other. Alternatively, the first capillary structures 131 and the second capillary structure 132 are overlapped with each other as upper layer and lower layer. In this embodiment, the first capillary structures 131 and the second capillary structure 132 are overlapped with each other. That is, each of two ends of the second capillary structure 132 has an extension section 1321. The extension sections 1321 respectively extend onto the first capillary structures 131 of the evaporator section 121 and the condenser section 123 and are overlapped with the first capillary structures 131 in contact therewith. Accordingly, when the support sections 1131 are angularly adjusted, the extension sections 1321 of the second capillary structure 132 will outward extend or inward retract on the first capillary structures 132. The thickness of the second capillary structure 132 of the support sections 1131 is larger than or equal to the thickness of the support sections 1131 so as to enhance the structural strength of the support sections 1131.

[0020] In a modified embodiment, the second capillary structure 132 is alternatively multiple second capillary structures 132 respectively disposed on inner walls of the support sections 1131 and the knot sections 1132. The second capillary structure 132 of the support sections 1131 and the knot sections 1132 are different capillary structures or complex capillary structures. The extension sections 1321 extending from two ends of the second capillary structures 132 of each support section 1131 extend onto the second capillary structures 132 of the adjacent knot sections 1132 and are overlapped with the second capillary structures 132 in contact therewith. In addition, the extension sections 1321 of the second capillary structures 132 of each support section 1131 in adjacency to the evaporator section 121 and the condenser section 123 extend onto the adjacent first capillary structures 131 and are overlapped with the first capillary structures 131 in contact therewith. Accordingly, when the support sections 1131 are angularly adjusted, the extension sections 1321 of the second capillary structure 132 of the support sections 1131 will outward extend or inward retract on the second capillary structures 132 of the knot sections 1132.

[0021] An outer side of the front section 111 of the sealed case body 11 is attached to and in contact with an electronic component (such as a central processing unit or a graphics processing unit, not shown) to absorb the heat generated by the electronic component. At this time, the working fluid in evaporator section 121 is heated and transformed into vapor working fluid. The vapor working fluid flows through the adiabatic section 112 to the condenser section 123 at a remote end to dissipate the heat outward. The vapor working fluid in the condenser section 123 is cooled and transformed into liquid working fluid. Then the liquid working fluid goes back to the evaporator section 121 under the capillary attraction of the first and second capillary structures 131, 132 of the capillary structure 13 on the inner wall of the chamber 12. Accordingly, the vapor-liquid two-phase transformation cycle is continuously repeated to achieve the remote end heat transfer and heat dissipation effect.

[0022] Please now refer to FIG. 3, which is a side view of the multi-angle adjustable and transformable heat pipe of the present invention, showing that the heat pipe of the present invention is transformed, adjusted and located by many angles. As shown in the drawing, when the front section 111 and the rear section 112 of the heat pipe 1 respectively contact different objects at different heights, the support sections 1131 of the middle section 113 are adjusted and arranged by different angles or the same angle with the adjacent knot sections 1132 serving as fulcrums. Moreover, after adjusted, all the support sections 1131 are restricted by the adjacent knot sections 1132 and located in the angular positions. Accordingly, the middle section 113 can be freely adjusted and transformed into various configurations in adaptation to the installation positions of the heat sources.

[0023] The present invention has been described with the above embodiments thereof and it is understood that many changes and modifications in such as the form or layout pattern or practicing step of the above embodiments can be carried out without departing from the scope and the spirit of the invention that is intended to be limited only by the appended claims.
