  • Patent number: 7839641
    Abstract: A condenser for a power module combines a plurality of aluminum materials to form a casing equipped with a channel for coolant therein, thus making it possible to keep material costs low. Moreover, thanks to the excellent workability of the aluminum materials, it is possible to adopt a configuration with a complex concave-convex configuration for a superior heat radiation performance. A channel for coolant with high heat radiation performance can also be structured inside the casing. The relatively thick bottom plate secures the rigidity required by the casing, while the relatively thin top plate can have a rigidity intentionally structured lower. In this manner, stress generated on joining surfaces of the condenser and an insulative substrate can be mitigated due to active deformation of the top plate.

  • Patent number: 7755899
    Abstract: The present invention is a thermally controlled switch with high thermal or electrical conductivity. Microsystems Technology manufacturing methods are fundamental for the switch that comprises a sealed cavity formed within a stack of bonded wafers, wherein the upper wafer comprises a membrane assembly adapted to be arranged with a gap to a receiving structure. A thermal actuator material, which preferably is a phase change material, e.g. paraffin, adapted to change volume with temperature, fills a portion of the cavity. A conductor material, providing a high conductivity transfer structure between the lower wafer and the rigid part of the membrane assembly, fills another portion of the cavity. Upon a temperature change, the membrane assembly is displaced and bridges the gap, providing a high conductivity contact from the lower wafer to the receiving structure.

  • Patent number: 7751192
    Abstract: A heatsink having tapered geometry that improves passive cooling efficiency is discussed. A tapered geometry between heatsink heat dissipation elements, as a function of distance along a z-axis opposing gravity, decreases resistance to rarification of passively flowing cooling gas upon heating. Thus, the tapered heatsink elements result in higher velocity of gas flow and increased cooling efficiency of the heatsink. Optionally, the heatsink is made from a thermally conductive polymer allowing the heatsink to be created in complex shapes using injection molding.

    Abstract: A computer adapted for force-air cooling of a processor. The computer includes a board supporting the processor and a heat sink mounted such with its base plate contacting the processor. A primary mount supports the heat sink near the processor, and a portion of the heat sink base plate extends outward a distance or overhang length from the primary mount to an edge. The apparatus includes a secondary heat sink mounting assembly supported upon the processor board that includes a damping element with an resilient body positioned proximate to the edge of the base plate, whereby the body abuts the base plate during movement of the base plate toward the board, e.g., upon application of a dynamic or shock load that causes the overhanging portions of the base plate of the heat sink to vibrate or oscillate about the support locations of the primary mount.
