  • Patent number: 8358505
    Abstract: A liquid cooling system includes a monolith that is configured to be coupled to a motherboard of the computer. The monolith may be monolithic planar body having a first surface and an opposite second surface, and may include a heat absorption region and a heat dissipation region. The heat absorption region may be at least one location on the monolith that is configured to be in thermal contact with a heat generating component of the motherboard, and the heat dissipation region may be at least one location on the monolith where a liquid-to-air heat exchanger is attached to the monolith. The liquid cooling system may also include a channel extending on the second surface of the monolith and a pump that is configured to circulate the liquid coolant through the channel. The channel may be a trench on the second surface of the monolith that is configured to circulate a liquid coolant between the heat absorption region and the heat dissipation region.

  • Patent number: 6492621
    Abstract: An apparatus for heat treatment of a wafer is disclosed. The apparatus includes a heating chamber having a heat source. A cooling chamber is positioned adjacent to the heating chamber and includes a cooling source. A wafer holder is configured to move between the cooling chamber and the heating chamber through a passageway and one or more shutters defines the size of the passageway. The one or more shutters are movable between an open position where the wafer holder can pass through the passageway and an obstructing position which defines a passageway which is smaller than the passageway defined when the shutter is in the open position.
