Description
- 1. Technical Field
- The present disclosure relates to heat dissipation devices, and more particularly to a heat dissipation device incorporating a heat spreader.
- 2. Description of Related Art
- Electronic components, such as central processing units (CPUs) comprising numerous circuits operate at high speed and generate substantive heat. Under most circumstances, it is necessary to cool the electronic components in order to maintain safe operating conditions and assure that the electronic components function properly and reliably. Typically, a finned metal heat dissipation device is attached to an outer surface of the electronic component to remove the heat therefrom. The heat absorbed by the heat dissipation device is then dissipated to ambient air.
- However, as the operating speed of the electronic components has been continually upgraded, these kinds of conventional heat dissipation devices can no longer meet the heat dissipation requirements of modern electronic components.
- What is needed, therefore, is a heat dissipation device which can overcome the above-described problems.
- Many aspects of the present heat dissipation device 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 heat dissipation device. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.

FIG. 5 is an inverted, exploded view of the heat dissipation device ofFIG. 1 . -
FIG. 6 is an inverted view of the heat dissipation device ofFIG. 1 . - Referring to
FIGS. 1 and 2 , a heat dissipation device in accordance with an exemplary embodiment of the disclosure is used for dissipating heat generated by an electronic component (not shown) mounted on a printed circuit board (not shown). The heat dissipation device comprises aheat spreader 10 for thermally contacting the electronic component, and afin set 20 disposed on theheat spreader 10. Theheat spreader 10 is flat. In this embodiment, theheat spreader 10 is rectangular in shape. Four throughholes 100 are defined at four corners of theheat spreader 10 for extension of four fasteners (not shown). - Referring to
FIGS. 3 and 4 also, theheat spreader 10 comprises abase 11, apartition board 12 hermetically placed on thebase 11, and acovering plate 13 hermetically placed on thepartition board 12. Thebase 11 is made of metal with good heat conductivity, such as aluminum, copper, or alloys thereof. Thebase 11 has a rectangular profile. A central portion of thebase 11 is recessed downwardly, thereby forming a first receiving portion 110 (as shown inFIG. 2 ). Thepartition board 12 seals the first receiving portion 110 to corporately form afirst chamber 111 between thebase 11 and thepartition board 12. In use, thefirst chamber 111 is vacuum-exhausted, and accommodates working medium therein. The working medium is selected from a liquid which has a relatively low boiling point, such as water, methanol, and alcohol. Afirst wick structure 114 is formed on a total inner face of the central portion of thebase 11 defining the first receiving portion 110. Thefirst wick structure 114 is selected from some suitable materials, such as sintered metal powder, metal mesh, carbon nanotube array, and bundle of fibers. Anempty zone 112 is defined below a periphery of thebase 11 and surrounds thefirst chamber 111. Thefirst chamber 111 is placed just above the electronic component. Besides the electronic component mounted on the printed circuit board, there are some other electronic components, so an area of thefirst chamber 111 is limited in a certain extent for avoiding interference with the other electronic components, and the other electronic components could be received in theempty zones 112. - Referring to
FIGS. 5 and 6 also, thepartition board 12 is a rectangular plate. Thepartition board 12 is made of metal with good heat conductivity, such as aluminum, copper, or alloys thereof. Asecond wick structure 120 is formed on a bottom face of thepartition board 12 in thefirst chamber 111. Thesecond wick structure 120 is selected from some suitable materials, such as sintered metal powder, metal mesh, carbon nanotube array, and bundle of fibers. When thepartition board 12 is assembled on thebase 11, an outer periphery of thesecond wick structure 120 is connected to thefirst wick structure 114. In other words, thefirst wick structure 114 cooperates with thesecond wick structure 120 to spread on a total inner face of thefirst chamber 111. Athird wick structure 122 is formed on a top face of thepartition board 12. Thethird wick structure 122 is selected from some suitable materials, such as sintered metal powder, metal mesh, carbon nanotube array, and bundle of fibers. - The
covering plate 13 is made of metal with good heat conductivity, such as aluminum, copper, or alloys thereof. Thecovering plate 13 has a rectangular profile. A center portion of thecovering plate 13 is protruded upwardly, thereby forming a second receivingportion 130. A periphery of thecovering plate 13 is anannular frame 132 surrounding the second receiving portion 130 (as shown inFIG. 3 ). Theframe 132 is hermetically attached on thepartition board 12, whereby thecovering plate 13 cooperates with thepartition board 12 to define asecond chamber 131 between thecovering plate 13 and thepartition board 12. In use, thesecond chamber 131 is vacuum-exhausted, and accommodates working medium therein. The working medium is selected from a liquid which has a relatively low boiling point, such as water, methanol, and alcohol. Thesecond chamber 131 is located above thefirst chamber 111. Thesecond chamber 131 is separated from thefirst chamber 111 by thepartition board 12. A cross sectional area of thesecond chamber 131 is larger than that of thefirst chamber 111. Afourth wick structure 134 is formed on a total inner face of the second receivingportion 130. Thefourth wick structure 134 is selected from some suitable materials, such as sintered metal powder, metal mesh, carbon nanotube array, and bundle of fibers. When thecovering plate 13 is assembled on thepartition board 12, an outer periphery of thefourth wick structure 134 is connected to thethird wick structure 122. In other words, thethird wick structure 122 cooperates with thefourth wick structure 134 to spread on a total inner face of thesecond chamber 131. Thesecond chamber 131 is remote from thebase 11 and is separated from thebase 11 by thepartition board 12. - The
fin set 20 comprises a plurality of parallel fins 21. A passage (not labeled) is defined between every two adjacent fins 21 to allow airflow to flow therethrough. Each of the fins 21 comprises an upright sheet body and a pair of flanges bent horizontally from top and bottom of the sheet body and engaging the sheet body of an adjacent fin 21. The flanges at a bottom face of the fin set 20 thermally contact a top face of the coveringplate 13. The fin set 20 occupies substantially the whole top face of the coveringplate 13 except locations where the throughholes 100 are located. - In use of the heat dissipation device, the
base 11 of theheat spreader 10 thermally contacts and absorbs heat from the electronic component. The working medium in thefirst chamber 111 is heated and vapored upwardly to reach thepartition board 12 of theheat spreader 10. At thepartition board 12, the vapored working medium exchanges heat with thepartition board 12 and then is condensed to liquid. The liquid refluences to thebase 11 via thesecond wick structure 120 and thefirst wick structure 114. As heat accumulated in thepartition board 12, the working medium in thesecond chamber 131 is heated and vapored upwardly to reach the coveringplate 13 of theheat spreader 10. Then the vapored working medium exchanges heat with the coveringplate 13 and then is condensed to liquid. The liquid refluences to thepartition board 12 via thefourth wick structure 134 and thethird wick structure 122. The vapored and condensed cycle continues, so heat absorbed by theheat spreader 10 is efficiently transferred to the fin set 20 placed on the coveringplate 13 to be dissipated into ambient. Thus, heat dissipation efficiency of the heat dissipation device is greatly improved. - It is to be understood, however, that even though numerous characteristics and advantages of the present embodiment(s) have been set forth in the foregoing description, together with details of the structures and functions of the embodiment(s), the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
