Abstract
A heat dissipation device (40) includes at least a heat pipe (45) and a plurality of metal fins (43) thermally connected to the heat pipe. Each of the metal fins defines therein an aperture (431). An extension flange (433) extends outwardly from the metal fin and surrounds the aperture. The extension flange defines therein a plurality of slits (435). The apertures and extension flanges of the metal fins are aligned together. The heat pipe is received in the aligned apertures and soldered by a thermal medium material to the metal fins via the aligned extension flanges. During the soldering process, rosin content contained in the thermal medium material can be discharged away via the slits formed in the extension flange.
Claims10
A heat dissipation device comprising:
- a heat pipe;
- and
- a plurality of metal fins thermally connected to the heat pipe, each of said metal fins defining therein an aperture, an extension flange extending outwardly from each of said metal fins and surrounding the aperture, the extension flange defining therein a plurality of slits, the apertures and extension flanges of said metal fins being aligned with one another, said heat pipe being received in the aligned apertures and soldered by a thermal medium material to the metal fins via the aligned extension flanges;
- wherein the extension flange has a distal end portion and the slits in the extension flange are separated from the distal end portion.
A heat dissipation device comprising:
- a fin defining an aperture therethrough and comprising an extension flange surrounding the aperture, the extension flange defining a plurality of voids therein, each of the voids neither reaching an end of the extension flange distant from the fin nor reaching the fin;
- a heat pipe extending through the aperture;
- and
- solder provided on contacting surfaces of the heat pipe and the extension flange and in the voids, the solder thermally and mechanically connecting the heat pipe and the extension flange of the fin together.
