Abstract
Description
- This application is a continuation of U.S. application Ser. No. 13/417,898 filed Mar. 12, 2012, the entire contents of which are hereby incorporated by reference.
- The instant disclosure relates to a flat heat pipe structure; more particularly, to a heat-moving flat heat pipe structure having internal support member.
- As the speed of a central processing unit (CPU) increases, more heat is given off by the CPU. The conventional heat dissipating device comprised of an aluminum heat sink and a fan can no longer accommodate the operational demand of today's CPU with increased clock speed. To address this issue, more powerful and capable heat pipes and vapor chambers have been developed to work with the heat sink.
- Due to adhesive characteristic of the porous capillary structure of the heat pipe and pressure differential across its walls, a support member is required to be disposed in the heat pipe, such that the tubing has enough supporting strength after being flattened. However, the conventional support member typically is very rigid and makes the tubing very difficult to bend. According to an issued Taiwan Patent (Patent #577538), a support member having saw tooth-shaped ridges is disclosed. One of the concerns is the capillary structure or the tubing may be worn and/or damaged by these saw tooth-shaped ridges. Some of other existing support members have complex structural features. When these types of support members are disposed in heat pipes, the flow of the working fluid is rerouted from its normal path, which would adversely affect the heat dissipation efficiency.
- To address the above issues, the inventors strive via industrial experience and academic research to present the instant disclosure, which can effectively improve the limitations described above.
- The instant disclosure provides a flat heat pipe structure having a bendable support member. The support member can prevent the walls of the heat pipe from deforming inwardly and crimping at the bending portions. Thus, the heat pipe is better suited for bending.
- Moreover, the instant disclosure provides a flat heat pipe structure having longitudinal passageways, where the path traveled by the working fluid is shortened.
- To achieve the aforementioned objects, the heat pipe structure of the instant disclosure comprises a flat tubing and a support member. The flat tubing has two opposed flat main walls and two opposed connecting walls. The main walls are connected by the connecting walls in forming an internal space. A capillary structure is formed on the inner surfaces of the flat tubing. The support member has at least one elongated support arm disposed inside the internal space and extends longitudinally therein. Every support arm has two opposed flat surfaces abutting the capillary structure on the main walls.
- Both sides of the support member are spaced apart from the connecting walls by a predetermined distance in the longitudinal direction of the heat pipe. The space created between each side of the support member and the corresponding connecting wall defines a longitudinal passageway for flowing the working fluid.
- For advantages, the main walls of the flat heat pipe structure provide additional strength for the annular tubing during the flattening process. After disposing the support member inside the heat pipe structure, the heat pipe structure can be bent without crimping. Moreover, the heat pipe structure and the support member cooperatively form internal passageways for circulating the working fluid. The longitudinal passageways provide a shorter path for the working fluid to travel.
- In order to further appreciate the characteristics and technical contents of the instant disclosure, references are hereunder made to the detailed descriptions and appended drawings in connection with the instant disclosure. However, the appended drawings are merely shown for exemplary purposes, rather than being used to restrict the scope of the instant disclosure.

FIG. 1 shows a top view of a flatheat pipe structure 1 of the instant disclosure, andFIG. 1A shows a cross-sectional view thereof taken along line AA inFIG. 1 . The flatheat pipe structure 1 comprises aflat tubing 10 and asupport member 20 disposed therein. Theflat tubing 10 is made with material with excellent thermal conductivity and malleability such as aluminum, aluminum alloy, copper, copper alloy, etc. Theflat tubing 10 is manufactured by flattening an annular tubing. For the instant embodiment, theflat tubing 10 is elongated and has a strip-like shape. Alternatively, theflat tubing 10 may be rectangular with a plate-like shape, where the exact structural shape of theflat tubing 10 is not restricted. - The
flat tubing 10 is defined by two opposedmain walls 12 and two opposedconnecting walls 14. Theconnecting walls 14 are connected between themain walls 12 and cooperatively form aninternal space 100. The opposite ends of theflat tubing 10 are welded closed to seal theflat tubing 10. Acapillary structure 16 is formed on the inner surfaces of theflat tubing 10. Namely, thecapillary structure 16 covers the inner surfaces of the main and connectingwalls capillary structure 16 may be provided in various forms such as a metal mesh, grooves, or a sintered body of metal powder. - The
support member 20 is preferably made of high temperature resistant and bendable material, such as copper. Thesupport member 20 has at least onesupport arm 21 disposed in theinternal space 100 of theflat tubing 10. For the instant embodiment, thesupport member 20 has threesupport arms 21 arranged in parallel to each other. Eachsupport arm 21 extends along the longitudinal direction or the long axis of theflat tubing 10. At least onesupport arm 21 has two opposed flat surfaces, namely, a top surface and a bottom surface, for the orientation shown inFIG. 1A . The top and bottom surfaces abut thecapillary structure 16 of themain walls 12. Thesupport arms 21 serve as structural supports for theflat tubing 10. Moreover, thesupport arms 21 and theflat tubing 10 cooperatively form a plurality ofpassageways 101, where thepassageways 101 are arranged in parallel to each other and extend longitudinally along theflat tubing 10. - The opposite sides of the
support member 20 extending in the longitudinal direction of theflat tubing 10 are spaced apart from the connectingwalls 14 by a predetermined distance. In other words, thesupport arms 21 do not touch the connectingwalls 14. The spaces formed between thesupport arms 21 and the connectingwalls 14 along the longitudinal direction of theflat tubing 10 serve asinternal passageways 101. Thepassageways 101 are in communication with both ends of the flatheat pipe structure 1. One end of the flatheat pipe structure 1 being the evaporator section for absorbing heat, and the other end being the condenser section for giving up latent heat of vaporization. At the condenser section, the working fluid changes from a vapor state to a liquid state. Theselongitudinal passageways 101 provide the shortest distance that the working fluid has to travel between opposite ends of the flatheat pipe structure 1, thus greatly raising the heat dissipation efficiency. It is worth noting thesupport arms 21 of thesupport member 20 may also be arranged touchingly to the respective connectingwalls 14, for preventing the connectingwalls 14 from deforming inwardly and crimping after bending. - Please refer to
FIG. 2 , which is a perspective view showing thesupport member 20 of the flatheat pipe structure 1. As described previously, thesupport member 20 of the instant embodiment has threesupport arms 21. Thesupport arms 21 are parallelly spaced apart from one another, where the number ofsupport arms 21 is not restricted. Thesupport member 20 may have more than onesupport arm 21, where thesupport arms 21 are equally spaced from one another inside theflat tubing 10. The distance betweenadjacent support arms 21 depends on the dimension of theflat tubing 10 along the short axis of theflat tubing 10. Thesupport member 20 further has a connectingportion 22 connecting to one end of eachsupport arm 21. The width of the connectingportion 22 is substantially equal to or less than the width of theinternal space 100 along the short axis of theflat tubing 10. Furthermore, the opposite ends of the connectingportion 22 do not have to extend normally beyond thesupport arms 21. The purpose of the connectingportion 22 is to maintain thesupport arms 21 spaced apart from each other. Especially after thesupport arms 21 have been disposed in the annular tubing, the connectingportion 22 prevents the misplacing of thesupport arms 21 during the flattening process. For the instant embodiment, the shape of the connectingportion 22 is rectangular but is not restricted thereto. For example, the connectingportion 22 may be a rod-shaped structure. Alternatively, thesupport member 20 may have two connectingportions 20. The second connectingportion 20 may be arranged on the other end of eachsupport arm 21. - Please refer to
FIG. 3 , which is a perspective view of the flatheat pipe structure 1 of the instant disclosure. The connectingportion 22 is arranged proximate to one end of theflat tubing 10. During the flattening process of the annular tubing, thesupport member 20 provides structural support to themain walls 12, thus preventing themain walls 12 from deforming inwardly or crimping. Whereas during the bending process of theflat tubing 10, thesupport member 20 also allows themain walls 12 to maintain smooth surfaces. The other advantage of the instant disclosure is the formation oflongitudinal passageways 101. Thepassageways 101 provide a shorter path for the working fluid to travel between the ends of theflat tubing 10. - Please refer to
FIG. 4 , which is a perspective view showing analternate support member 20 a. For thesupport member 20 a, asecond capillary structure 23 is formed on the opposed side surfaces of eachsupport arm 21. Similarly, thecapillary structure 23 may be provided in various forms such as a metal mesh, grooves, a sintered body of metal powder, or a composite capillary structure. - Please refer to
FIG. 5 , which is a cross-sectional view of thesupport member 20 a shown inFIG. 4 and a flat heat pipe structure 1 a. Based on the aforementioned structural features of thesupport member 20 a, thecapillary structures passageways 101. In other words, the inners walls that define eachpassageway 101 are covered with capillary structures. The addition of thesecond capillary structure 23 further enhances the heat dissipation efficiency of the heat pipe structure 1 a. - Please refer to
FIG. 6 , which is a cross-sectional view showing aheat pipe structure 1 b for a third embodiment of the instant disclosure. The instant embodiment is particularly suitable in cases where a heat pipe is required to be bent. The width or the lateral dimension of theheat pipe structure 1 b is not restricted. When theinternal space 100 within theheat pipe structure 1 b is more limited, theheat pipe structure 1 b may include only onesupport arm 21 b, as illustrated inFIG. 6 . Moreover, thesingle support arm 21 b and aflat tubing 10 b cooperatively form twolongitudinal passageways 101. - Based on the foregoing descriptions, the
main walls 12 provide additional strength for the annular tubing during the flattening process. The instant disclosure is especially suitable in cases where a heat pipe is required to be bent. A smooth surface can be maintained at the bent portion of the flat heat pipe structure without crimping. Especially for large sized flat heat pipe structure, a smooth surface can be maintained across themain walls 12. Moreover, after the support member has been disposed in the flat heat pipe structure, the heat pipe structure can still be bent as needed. In addition, the formation of longitudinal passageways provides a short path for transporting the working fluid. - The descriptions illustrated supra set forth simply the preferred embodiments of the instant disclosure; however, the characteristics of the instant disclosure are by no means restricted thereto. All changes, alternations, or modifications conveniently considered by those skilled in the art are deemed to be encompassed within the scope of the instant disclosure delineated by the following claims.
