FIG. 20 is a bottom view of a radial heat sink in accordance with a seventh embodiment of the present invention. -
FIG. 21 is a sectional view taken along line A-A ofFIG. 20 . - Referring to
FIGS. 1-5 , a radial heat sink in accordance with the present invention is shown comprising acore base 1, a plurality ofradiation fins 2, and at least one, for example U-shaped,heat pipe 3. - The
core base 1 is a tubular metallic member. Theradiation fins 2 are equiangularly fastened to the periphery of thecore base 1. The U-shapedheat pipe 3 is mounted inside thecore base 1. Thecore base 1 has mountinggrooves 11 located on the inside wall thereof for receiving the U-shapedheat pipe 3. When the two distal ends of the U-shapedheat pipe 3 are respectively press-fitted into onerespective mounting groove 11 in thecore base 1, themiddle part 31 of the U-shapedheat pipe 3 is exposed to the outside of thecore base 1 for direct contact with the heat-emitting device (CPU, LED lamp, or any other electronic component part that emits heat during its operation) for quick dissipation of waste heat from the heat-emitting device. - As shown in
FIG. 6 , themounting grooves 11 extend axially along the inside wall of thecore base 1. Thecore base 1 has its one end opened (seeFIG. 3 ), and its other end closed, i.e., provided with an end wall 12 (seeFIG. 4 ). Thecore base 1 further has a plurality ofmounting holes 121 cut through theend wall 12, and two throughholes 13 cut through theend wall 12 and a locatinggroove 14 located on the outer surface of theend wall 12 and extending between the two throughholes 13. The two distal ends of theU-shaped heat pipe 3 are respectively inserted through the two throughholes 13 into therespective mounting grooves 11 in thecore base 1 to let themiddle part 31 be press-fitted into the locatinggroove 14. Further, themiddle part 31 of the U-shapedheat pipe 3 has a flat outer surface kept in flush with the outer surface of the end wall 12 (seeFIG. 5 ). - The design of the aforesaid two through
holes 13 is adapted for the mounting of theU-shaped heat pipe 3. According to the embodiment shown inFIGS. 16 and 17 , an L-shaped heat pipe is used wherein the vertical end of the L-shaped heat pipe is inserted through one throughhole 13 into onemounting groove 11, and the horizontal end of the L-shaped heat pipe is press-fitted into the locatinggroove 14 and kept in flush with the outer surface of theend wall 12. To fit this application example, it simply needs to make one single throughhole 13 for the mounting of the L-shaped heat pipe. - Further, the
core base 1 can be made having arib 111 extending along each of two opposite sides of each of themounting grooves 11 and the locating groove 14 (seeFIG. 1 ,FIG. 3 orFIG. 7 ). After theheat pipe 3 is press-fitted into themounting grooves 11 and the locatinggroove 14, theribs 111 are deformed to clamp theheat pipe 3, enhancing the tightness of the connection between thecore base 1 and theheat pipe 3, and therefore no further soldering procedure is necessary. - Similar to conventional techniques, the quantity, configuration or distribution arrangement of the
radiation fins 2 can be changed according to different requirements. For example, theradiation fins 2 can be arranged around the whole or a part of the periphery of thecore base 1. There are no limitations with respect to the connection between theradiation fins 2 and thecore base 1. Theradiation fins 2 can be formed integral with the peripheral wall of thecore base 1. Alternatively, theradiation fins 2 can be fastened to the peripheral wall of thecore base 1 by insertion or by soldering. - As shown in
FIG. 7 , theribs 111 protrude from the inside wall of thecore base 1 and respectively extend along the two opposite lateral sides of the mountinggroove 11. By means of using stamping dies 5 to impart a pressure to eachrib 111 toward the mounting groove 11 (see the direction of the arrowhead sign), theribs 111 are deformed (seeFIG. 8 ) and clamped on theheat pipe 3, securing theheat pipe 3 tightly to the mounting groove 11 (seeFIG. 8 andFIG. 9 ). - Further, as shown in
FIG. 10 , anannular packing plate 4 can be fastened to the bottom side of thecore base 1 and stopped against the bottom edge of each of theradiation fins 2. After installation, the bottom surface of theannular packing plate 4 is kept in flush with the outer surface of theend wall 12 and the flat outer surface of themiddle part 31 of the heat pipe 3 (seeFIG. 11 ). - According to the design of the present invention, the number of the at least one
heat pipe 3 can be increased or reduced to fit different application requirements. As shown inFIG. 12 andFIG. 13 , thecore base 1 hasmultiple mounting grooves 11 and locatinggrooves 14, and threeU-shaped heat pipes 3 are respectively press-fitted into the mountinggrooves 11 and/or the locatinggrooves 14. Further, L-shaped heat pipes or heat pipes of other configurations may be used to substitute for theU-shaped heat pipes 3. - Further, the
core base 1 can be made in a cylindrical shape, a rectangular shape, a polygonal shape, or any of a variety of other configurations, with at least one heat pipe set therein. The mountinggrooves 11 are configured to fit the heat pipes.FIGS. 14 and 15 illustrate the use of arectangular core base 1. Except the configuration, the structural characteristics of thecore base 1, theradiation fins 2 and theheat pipes 3, the design of theribs 111 and the arrangement of themiddle part 31 of theheat pipe 3 in flush with the outer surface of theend wall 12 remain unchanged. -
FIGS. 16 and 17 illustrate the use of an L-shapedheat pipe 3 a. According to this embodiment, thecore base 1 has only one single throughhole 13 for the insertion of the L-shapedheat pipe 3 a so that the vertical end and horizontal end of the L-shapedheat pipe 3 a can be respectively press-fitted into the mountinggroove 11 and the locatinggroove 14. -
FIGS. 18 and 19 illustrate the use of astraight heat pipe 3 b. According to this embodiment, thestraight heat pipe 3 b is press-fitted into the locatinggroove 14 of thecore base 1 and kept in flush with the outer surface of theend wall 12 of thecore base 1. Therefore, thecore base 1 according to this embodiment does not provide theaforesaid mounting grooves 11 or throughholes 13. Further, thecore base 1 can be made having multiple locatinggrooves 14 for the mounting of multiplestraight heat pipes 3 b. -
FIGS. 20 and 21 illustrate the use of anarched heat pipe 3 c. According to this embodiment, thearched heat pipe 3 b is press-fitted into thearched locating groove 14 c on theend wall 12 of thecore base 1 and kept in flush with the outer surface of theend wall 12 of thecore base 1. Therefore, thecore base 1 according to this embodiment does not provide theaforesaid mounting grooves 11 or throughholes 13. Further, thecore base 1 can be made having multiplearched locating grooves 14 c for the mounting of multiplearched heat pipes 3 b. - Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
