  • Composite liquid cooled plate for electronic equipment
    Patent number: 5159529
    Abstract: A composite liquid cooled plate is disclosed having a heat transfer plate, preferably made of copper, on one or both sides of a core, which is preferably plastic. The core has flow channels to direct water against the heat transfer plates underneath the "hot" areas of the heat transfer plates, thereby providing a very low thermal resistance. The assembly remains lightweight by restricting the use of copper or other conducting materials to only the areas requiring thermal conduction.
    Type: Grant

  • Ceramic base component packaging assembly
    Patent number: 5140298
    Abstract: A ceramic base component packaging assembly with high thermal transfer rates. The packaging assembly includes a molded plastic cover that receives spring washers, ceramic pads, resistive elements or other electronic components, and a thermally conductive ceramic base. The spring washers press the electronic elements against the ceramic base ensuring good thermal transfer. The ceramic base is an effective thermal conductor and electrical isolator for the device.
