A heat dissipation device for an integrated circuit includes a heat-conducting base plate having a bottom surface which is adapted to contact the upper surface of the integrated circuit, and a corrugated porous heat dissipating plate made of a flexible heat conducting material and fixed on the upper surface of the base plate so as to transfer heat from the base plate to the heat dissipating plate for heat dissipation. The heat dissipating plate has a plurality of ventilation holes formed therethrough, which are located over the base plate so as to enhance currents of air in the spaces between the base plate and the heat dissipating plate. Accordingly, the heat dissipating area in a unit of the space occupied by the heat dissipating plate is large enough to offer a quick and effective heat dissipation. Preferably, the base plate is made of an insulating material so as to prevent electric conduction from the integrated circuit to the base plate in case that the insulating coating of the integrated circuit is broken.
A heat dissipation device for an integrated circuit, comprising:
A heat dissipation device for an integrated circuit, comprising a heat-conducting base plate having a bottom surface which is adapted to contact an upper surface of the integrated circuit, and a corrugated heat dissipating plate made of a sheet of imperforate heat conducting material and fixed on an upper surface of said base plate, said corrugated heat dissipating plate having a plurality of first bent portions in contact with said base plate, a plurality of second bent portions extending away from said base plate, regions between said first bent portions and second bent portions, and a plurality of ventilation holes formed in said corrugated heat dissipating plate within said second bent portions and said regions, said first bent portions being free of said ventilation holes.
