Abstract
A heat dissipation device includes a core including a base with a bottom face and a top face and a body extending from the top face of the base, thermally conductive medium spread on the bottom face fo the base, a plurality of fin stacked along the body above the base, and a protective cover firmly disposed around the base of the core. An offset exists between the bottom face of the cover and the spread area of the medium.
Claims14
A combination comprising:
- a core comprising a base with a bottom face adapted for spreading a thermally conductive medium thereon, and a body extending from a top face of the base;
- a plurality of fins extending from the body above the base;
- a cover firmly disposed around the base of the core;
- and
- a bottom plate enclosing the bottom of the cover and spaced from the bottom face of the base to thereby forming an enclosed cavity between the bottom plate, the cover and the base for enclosing the medium therein.

A combination comprising:
- a heat dissipation device having a core with a face having a size substantially same as a heat-generating electronic component so as to contact said heat-generating electronic component by means of said face, a plurality of heat-dissipation fins extending from said core to dissipate heat of said heat-generating electronic component transmitted via said core;
- a thermally conductive medium spread on said face of said core in an area substantially same as said size of said face, said thermally conductive medium having a first thickness away from said face of said core;
- and
- a protective cover disposed around said surface of said core, said protective cover providing a receiving space to receive said thermally conductive medium incorporating with said surface of said core, and a second thickness of said protective cover away from said face of said core being larger than said first thickness.
