Abstract
Description
- The present application is a divisional application of U.S. patent application Ser. No. 12/489,418 filed on Jun. 22, 2009, having an attorney docket number of US23104 and entitled “FLAT HEAT PIPE”. The disclosure of such parent application is incorporated herein by reference.
- 1. Technical Field
- The present invention relates generally to an apparatus for transfer or dissipation of heat from heat-generating components, and more particularly to a heat pipe applicable in electronic products such as personal computers for removing heat from electronic components installed therein.
- 2. Description of Related Art
- Heat pipes have excellent heat transfer performance due to their low thermal resistance, and are therefore an effective means for transfer or dissipation of heat from heat sources. Currently, flat heat pipes are widely used for removing heat from heat-generating components such as central processing units (CPUs) of computers, especially in a notebook computer having a smaller inner space therein. Preferably, a wick structure is attached to an inner surface of the heat pipe for drawing the working medium back to the evaporator section after it is condensed at the condenser section. An inner surface of the wick structure defines a vapor channel through which vapor moves from the evaporator section toward the condenser section. With the notebook computer becoming smaller and smaller, the flat heat pipe becomes flatter and flatter and a size of the vapor channel is greatly reduced. Thus, the vapor can not flow fluently from the evaporator section toward the condenser section via the vapor channel, thereby decreasing the heat transfer capability of the flat heat pipe.
- Therefore, it is desirable to provide a flat heat pipe with an improved heat transfer capability to overcome the above mentioned shortcoming
- Many aspects of the present embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.

FIG. 1 is a front view of a heat pipe in accordance with a first embodiment of the present invention. -
FIG. 2 is a transverse cross-sectional view of the heat pipe ofFIG. 1 . -
FIG. 3 is a transverse cross-sectional view of a heat pipe in accordance with a second embodiment of the present invention. - Referring to
FIGS. 1 and 2 , aflat heat pipe 10 includes an elongated,flat casing 12, and awick structure 15 received in thecasing 12, wherein thewick structure 15 has a plurality of pores therein and is saturated with a working medium. Theflat heat pipe 10 is typically suitable for use in portable electronic devices such as notebook computers which have a limited space therein for accommodating heat dissipation devices. - The
casing 12 is made of a highly thermally conductive material such as copper or aluminum. Thecasing 12 includes anevaporator section 121 and acondenser section 122 at two opposite sides thereof along a longitudinal direction thereof. - A height h of the
casing 12 is below 1.2 millimeters. Thecasing 12 has a firstlateral portion 13 at a left lateral side thereof and a secondlateral portion 14 at a right lateral side thereof along a transverse direction. The firstlateral portion 13 is C-shaped in profile and includes anupper plate 131 at a top side thereof, abottom plate 132 at a bottom side thereof and opposite to theupper plate 131, and an outwardlycurved side plate 133 connecting theupper plate 131 with thebottom plate 132. The secondlateral portion 14 is C-shaped, with an opening of the secondlateral portion 14 facing an opening of the firstlateral portion 13. The secondlateral portion 14 includes anupper plate 141 at a top side thereof, abottom plate 142 at a bottom side thereof and opposite to theupper plate 141, and an outwardlycurved side plate 143 connecting theupper plate 141 with thebottom plate 142. Theupper plate 131 of the firstlateral portion 13 and theupper plate 141 of the secondlateral portion 14 cooperatively form anupper plate 124 of thecasing 12, and thebottom plate 132 of the firstlateral portion 13 and thebottom plate 142 of the secondlateral portion 14 cooperatively form abottom plate 125 of thecasing 12. - In the embodiment, the
wick structure 15 is a single-layered mesh-type structure, which is formed by weaving a plurality of metal wires, such as copper, or stainless steel wires. A plurality of pores is formed in themesh wick structure 15, which provides a capillary action to the working medium. - The
mesh wick structure 15 is received in thecasing 12 and extends along the longitudinal direction of thecasing 12. Themesh wick structure 15 has a C-shaped transverse cross section, with an opening of themesh wick structure 15 facing the opening of the firstlateral portion 13 of thecasing 12. Themesh wick structure 15 includes a firstupper section 151 parallel to theupper plate 141 of the secondlateral portion 14 of thecasing 12, asecond bottom section 152 opposite to the firstupper section 151, and acurved side section 153 connecting the firstupper section 151 with thesecond bottom section 152. Themesh wick structure 15 is attached to an inner surface of the secondlateral portion 14 of thecasing 12, with the firstupper section 151 being attached to theupper plate 141 of the secondlateral portion 14 of thecasing 12, thesecond bottom section 152 being attached to thebottom plate 142 of the secondlateral portion 14 of thecasing 12, thecurved side section 153 being attached to theside plate 143 of the secondlateral portion 14 of thecasing 12. No wick structure is attached to an inner surface of the firstlateral portion 13 of thecasing 12. The inner surface of the firstlateral portion 13 defines afirst vapor channel 16 in theheat pipe 10, and an inner surface of themesh wick structure 15 defines asecond vapor channel 17 in theheat pipe 10. Thefirst vapor channel 16 and thesecond vapor channel 17 communicate with each other at a joint between the first and the secondlateral portions casing 12. Thefirst vapor channel 16 has a height greater than thesecond vapor channel 17. - In an alternative embodiment, the C-shaped
mesh wick structure 15 is attached to the inner surface of the firstlateral portion 13 of thecasing 12, with an opening of themesh wick structure 15 facing the opening of the secondlateral portion 14, and no wick structure is attached to the inner surface of the secondlateral portion 14 of thecasing 12. - The working medium is saturated in the
mesh wick structure 15 and is usually selected from a liquid such as water, methanol, or alcohol, which has a low boiling point and is compatible with themesh wick structure 15. Thus, the working medium can easily evaporate to vapor when it receives heat at theevaporator section 121 of theheat pipe 10. - In operation, the
evaporator section 121 of theheat pipe 10 is placed in thermal contact with a heat source, for example, a central processing unit (CPU) of a computer, which needs to be cooled. The working medium contained in theevaporator section 121 of theheat pipe 10 is vaporized into vapor upon receiving the heat generated by the heat source. Then, the generated vapor moves via thevapor channels condenser section 122 of theheat pipe 10. After the vapor releases the heat carried thereby and is condensed into the liquid in thecondenser section 122, the liquid is brought back by themesh wick structure 15 to theevaporator section 121 of theheat pipe 10 for being available again for evaporation. - Since the
mesh wick structure 15 is only attached to the secondlateral portion 14 of thecasing 12, thefirst vapor channel 16 has a height greater than thesecond vapor channel 17, whereby thefirst vapor channel 16 is very unlikely to be blocked when theheat pipe 10 is flattened. Even if thesecond vapor channel 17 is somewhat blocked by the firstupper section 151 and thesecond bottom section 152 of themesh wick structure 15, the vapor can also flow freely through thefirst vapor channel 16 from theevaporator section 121 toward thecondenser section 122. Thus, the height of thecasing 12 can be reduced to be less than 1.2 millimeters, such as 1.0 millimeter or 0.8 millimeter, while theheat pipe 10 still can function normally. Compared with a typical conventional heat pipe, theheat pipe 10 of the first embodiment can be made thinner and therefore is more suitable to be used in compact electronic devices, such as notebook computers. -
FIG. 3 shows aflat heat pipe 30 in accordance with a second embodiment of the present invention. The difference of this embodiment over the previous embodiment is as follows. Thewick structure 35 is flat and attached only to an inner surface of thebottom plate 312 of thecasing 31 and spaced from theupper plate 311 of thecasing 31. - It is believed that the present embodiments 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 invention or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments of the invention.
