Description
- 1. Field of the Invention
- The invention relates to heat transfer apparatuses and, more particularly, to a flat heat pipe with enhanced heat dissipation efficiency.
- 2. Description of Related Art
- Generally, flat heat pipes can efficiently dissipate heat from heat-generating components such as central processing units (CPU). A conventional flat heat pipe includes a hollow cover, a continuous wick structure mounted on an inner surface of the cover and working medium contained in the wick structure. A vapor chamber is defined between an inner surface of the wick structure. When the cover absorbs heat generated from the heat-generating components, the working medium is vaporized by the heat and enters into the vapor chamber in all directions of the inner surface of the wick structure. Therefore, the vaporized working medium from different directions of the wick structure tends to interfere with each other and forms turbulence. Thus, heat dissipation efficiency and stability performance of the flat heat pipe are badly affected.
- What is needed is a flat heat pipe which can overcome the problem of the prior art.
-
FIG. 1 is a schematic view of a flat heat pipe along a transverse direction thereof in accordance with an embodiment of the disclosure. -
FIG. 2 is a schematic view of the flat heat pipe ofFIG. 1 along a longitudinal direction thereof. - Referring to
FIG. 1 , aflat heat pipe 1 in accordance with an embodiment of the disclosure includes ahollow cover 10, a restrictingplate 30 received in thecover 10 and abutting against thecover 10, awick structure 50 mounted on the restrictingplate 30, and a working medium (not shown) contained in thewick structure 50. Theflat heat pipe 1 is used to thermally connect with heat-generating components (not shown) to absorb heat generated therefrom. - The
cover 10 is integrally formed by one piece of metal such as copper or brass. Thecover 10 includes an elongatedtop plate 11, anelongated bottom plate 13 spaced from and facing thetop plate 11, and two convex connectingplates 15 located at lateral sides of theflat heat pipe 1 and interconnecting lateral edges of the top andbottom plates bottom plates top plate 11, thebottom plate 13 and the connectingplates 15 cooperatively define areceiving chamber 17 therebetween. - The
wick structure 50 is a screen made of wires mesh or a sintered body sintered by metal powder. Thewick structure 50 is an elongated strip and located at a central portion of thereceiving chamber 17 along a longitudinal direction of thecover 10. Top and bottom ends of thewick structure 50 abut against central portions of thetop plate 11 and thebottom plate 13, respectively. A transverse section of thewick structure 50 is substantially “II” shaped. Thewick structure 50 includes aneck portion 51 and two adheringportions 53 located at top and bottom ends of theneck portion 51, respectively. Theneck portion 51 has a length along the longitudinal direction of thecover 10 equal to that of each adheringportion 53, and a width along a transverse direction of thecover 10 less than that of each adheringportion 53. Theneck portion 51 connects central portions of the adheringportions 53. The adheringportions 53 are respectively adhered to the central portions of the top andbottom plates portion 53 is larger than that of thenecking portion 51. One of the adheringportions 53 and thenecking portion 51 cooperatively form a bugle-shaped configuration. Edges of thewick structure 50 are rounded. Therefore a contacting area of thewick structure 50 contacting the vaporized working medium is increased relative to the conventional wick structure without rounded edges. - The restricting
plate 30 is elongated, and made of a material having good heat transferring performance and compressive capacity, such as metal. The restrictingplate 30 has a length along the longitudinal direction of thecover 10 equal to that of thereceiving chamber 17. A height of the restrictingplate 30 is equal to a distance between inner surfaces of the top andbottom plates plate 30 is arranged in a middle of thereceiving chamber 17 along the longitudinal direction of thecover 10. Top and bottom ends of the restrictingplate 30 abut against the inner surface of thetop plate 11 and thebottom plate 13, respectively. The restrictingplate 30 divides thereceiving chamber 17 into afirst passage 171 and asecond passage 173 along the longitudinal direction of thecover 10. Thefirst passage 171 and thesecond passage 173 are hermetical and not in communication with each other. The restrictingplate 30 divides thewick structure 50 into twowick portions 55 along a longitudinal direction of thewick structure 50. The twowick portions 55 are symmetrical relative to restrictingplate 50 and adhered on opposite lateral surface of the restrictingplate 30, respectively. The twowick portions 55 are located in the first andsecond passages second passage - Referring also to
FIG. 2 , in operation, when one end, i.e. an evaporating section, of theflat heat pipe 1, absorbs heat generated from the heat-generating components, the working medium in thewick portions 55 of thewick structure 50 in the evaporating section is vaporized by the absorbed heat and enters into thefirst passage 171 and thesecond passage 173 from the inner lateral sides of thefirst passage 171 and thesecond passage 173, respectively. The vaporized working medium flows individually along thefirst passage 171 and thesecond passage 173 to another end of the flatpipe heat pipe 1, i.e. a condensing section opposite to the evaporating section, to release heat thereof. After the vaporized working medium releases its heat and condenses in the condensing section, the condensed working medium is returned by thewick portions 55 to the evaporating section, where the condensed working medium is again available for evaporation and goes on a phase-change circulation. - Referring to
FIG. 1 again, in this embodiment, the width of the adheringportion 53 is larger than that of thenecking portion 51. The capillary force of the adheringportions 53 is larger than thenecking portion 51. Therefore, during operation, the working medium condensed on thetop plate 11 can be rapidly absorbed by the adheringportion 53 mounted on thetop plate 11 and flow towards theneck portion 51, and then the condensed working medium in theneck portion 51 can be rapidly guided back thebottom plate 13 via the adheringportion 53 mounted on thebottom plate 13 to avoid theflat heat pipe 1 overheating. - In addition, the vaporized work medium enters into the
first passage 171 and thesecond passage 173 only from the lateral sides of thefirst passage 171 and thesecond passage 173, so the vaporized work medium enters into thefirst passage 171 or thesecond passage 173 in a smaller angle relative to the conventional flat heat pipe. Thus, interference between the vaporized work medium in thefirst passage 171 or thesecond passage 173 is decreased relative to the conventional flat heat pipe. A probability of forming turbulence of the vaporized work medium is decreased. Furthermore, a stability of theflat heat pipe 1 is also improved via opposite ends of therestricting plate 30 abutting thetop plate 11 and thebottom plate 13, simultaneously. - It is believed that the disclosed embodiment(s) and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the disclosure or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments of the disclosure.
