A cooler includes a heat conducting member and a heat scattering member. The heat conducting portion is closely attached with a heat source. The heat scattering member has plural hollow cones respectively formed of sintered metallic particles with their size enlarged gradually from the bottom to the top. The metallic particles closer to the surface of the heat conducting member are smaller, having a greater contact area to transmit the heat more effectively. And, plus the ventilation of a fan on the heat scattering member, the air in the hole of the holl...
What is claimed is: 1. A cooler comprising: a heat conducting member shaped as a flat plate; and, a heat scattering member located on said conducting portion and consisting of plural hollow cones; each said hollow cone formed of sintered particles with a particle size enlarged gradually from the bottom to the top. 2. A cooler as claimed in claim 1, wherein said particles are made of a good heat conductive metal. 3. A cooler as claimed in claim 1, wherein each said hollow cone has a diameter in its central hole enlarged gradually from the bottom to ...
