Patent ID: 8842437

Claim:
A combinational chassis featuring heat dissipation, comprising: a chassis body, comprising a base plane shell, and a first side shell and a second side shell, of which the first side shell and the second side shell are extending in a same direction from two opposite sides of the base plane shell; the chassis body being formed with an outside surface and an inside surface; a free end of the first side shell being formed with a first end joint and a free end of the second side shell being formed with a second end joint, the first joint end configured to mate with the second joint end of a second one of the chassis body and the second joint end configured to mate with the first joint end of the second one of the chassis body; the base plane shell, the first side shell, and the second side shell being of a heat-sink material and being made all in one; and a heat dissipation device comprising a plurality of heat-sink parts deposited on the outside surface of chassis body, each of the plurality of heat-sink parts being identical to each other; each heat-sink part of the plurality of heat-sink parts comprising a heat-sink raised portion integrally protruding outwards from the outside surface of the chassis body, and a heat-sink joint portion geometrically protruding outwards of the heat-sink raised portion; and being made adjacent to the heat-sink raised portion; a wedge groove formed between the heat-sink raised portion and the heat-sink raised portion of an adjacent heat-sink part of the plurality of heat-sink parts; and an inlet groove connecting and communicating with the wedge groove, the inlet groove formed between the heat-sink joint portion and the heat-sink joint portion of the adjacent heat-sink part of the plurality of heat-sink parts; the heat-sink raised portion and the heat-sink joint portion being configured to wedge respectively to the wedge groove and the inlet groove of a third one of the chassis body.
