  • Patent number: 7663876
    Abstract: A water-cooled heat dissipation device for a notebook computer includes primarily a pad and a heat dissipation device at a bottom of the pad having an air through-hole. The heat dissipation structure has a fan below a U-shape plate, a groove of which is latched with parallel fins being transfixed with a metallic tube in a detouring way, with two ends of the metallic tube being connected to a water pump, allowing cooling water to circulate in the metallic tube to cool down the fins. The heat dissipation structure is fixed below the air through-hole of the pad with the two ends of the U-shape plate. In usage, a notebook computer is put on the pad, and temperature of the notebook computer is conducted to the pad. Furthermore, cold wind is blown to the pad by the fan, such that the notebook computer can be cooled down rapidly.

  • Patent number: 7650762
    Abstract: A burn-in oven is provided with a plurality of spaced, stacked burn-in-boards, each with a plurality of individual circuits being tested under heated conditions, and a plurality of valve trays positioned between two burn-in-boards to form a heat exchange compartment below the valve tray. Each valve tray has a plenum formed above it to provide a separate chamber that is a source of cooling air. Each valve tray has a plurality of valves, one over each of a number openings in the tray. Each opening overlies an integrated circuits or device under test on the burn-in-board below the valve tray. The valves control the flow of air for cooling the integrated circuits. The flow of air through the valves is the only path for cooling airflow to the integrated circuits on the burn-in-boards.

    Abstract: A switch-mode power supply (SMPS) with auto-tuning using limit-cycle oscillation response evaluation provides optimized performance with reduced capacitance and inductance requirements for a given design. During operation of the SMPS, parameters of the converter are extracted, and the feedback and/or feed-forward compensation is adjusted to either hold the loop bandwidth of the converter near the critical bandwidth of the output capacitors, or maintain output voltage transients within a specified limit. The compensator response is either periodically updated, or is updated in response to an event, such as detection of a transient voltage spike having a characteristic that exceeds one or more predetermined thresholds.

  • Patent number: 7495914
    Abstract: Electronic circuit boards are arranged as respective parallel pairs defining a narrow gap there between. One or more such pairs of boards are supported within a hermitically sealable housing and cooled by way of spraying an atomized liquid coolant from a plurality of nozzles into each narrow gap. Transfer of heat from the circuit boards results in vaporization of at least some of the atomized liquid within the narrow gap. The housing further serves to guide a circulation of vapors out of each narrow gap, back toward the nozzles, and back into each narrow gap. A heat exchanger exhausts heat from the housing and overall system, wherein vapor is condensed back to liquid phase during contact and heat transfer therewith. Condensed liquid is collected and re-pressurized for delivery back to the nozzles such that a sustained cooling operation is performed.

  • Patent number: 7477517
    Abstract: Disclosed is an integrated active heat spreader and exchanger. The heat spreader cum exchanger includes a housing with a conductive heat spreader therein. A spreader plate of the heat spreader is in thermal contact with a microprocessor chip to be cooled and a plurality of spreader fins extending from the spreader plate. A membrane connects the heat spreader and the housing, sealing an interface between the heat spreader and the housing. A top plate, including a plurality of top plate fins, is disposed in the housing. A pump is located between the top plate fins and the spreader fins and urges fluid across the spreader fins and conducts heat from the spreader fins. The top plate fins conduct heat from the fluid and into a heat sink in thermal contact with the top plate. A heat sink plate conducts heat into heat sink fins where the heat is dissipated.
