Abstract
A heat dissipation device includes a base, a first and second fin sets on the base, and a fan located atop the first and second fin sets. The base has a first face for contacting with an electronic device, and two sloped faces extending from the first face and toward each other. The first fin set defined a channel receiving the base therein. A plat extends from an end of the first face of the base. The second fin set is arranged on the plat of the base. The first face of the base has two grooves defined therein. A retaining member is attached to the first face of the base and has two retaining bars thereof fitted in the two grooves of the first face, respectively.
Claims20
A heat dissipation device comprising:
- a base having a first face for contacting with an electronic device, and two sloped faces extending from the first face and toward each other, a plat extending from an end of the base and having a bottom surface coplanar with the first face;
- a first fin set spanning on the base, comprising a plurality of first fins and a plurality of passages defined between the first fins, each of the first fins thermally contacting with the two sloped faces of the base;
- a second fin set arranged on the plat of the base, comprising a plurality of second fins and a plurality of passages defined between the second fins;
- and
- a fan located atop the first and second fin sets.
A heat dissipation device comprising:
- a base comprising a first face and two sloped faces extending from the first face and toward each other, a plat extending from an end of the base and having a bottom surface coplanar with the first face, the first face defining two grooves therein;
- a first fin set defining a channel receiving the base therein, the first fin set comprising a plurality of fins thermally contacting with the two sloped faces of the base;
- a second fin set comprising a plurality of fins arranged on the plat of the base;
- and
- a retaining member attached to the first face of the base, the retaining member comprising two retaining bars fitted in the two grooves of the first face, respectively, the retaining member being adapted for securing the heat dissipation device to a printed circuit board.
A heat dissipation device comprising:
- a base having a bottom face adapted for contacting with a heat-generating electronic component, two sloped faces extending from the bottom face of the base upwardly toward each other, and a plate extending outwardly from an end of the base;
- a first fin set mounted on the two sloped face of the base and a second fin set mounted on the plate of the base, the first fin set having a concave in a top thereof, the second fin set located beside the concave of the first fin set;
- and
- a fan mounted in the concave and having a portion extending to the second fin set.
