  • Patent number: 7791876
    Abstract: A hinge for moving two parts of an electronic apparatus relative to each other is disclosed. The hinge includes two coolant flow paths helically arranged between inlet and outlet connections as portions of the hinge are rotated relative to each other. Guide plates within the hinge independently rotate to suitably position the conduits of the coolant flow paths in a position of minimum twisting and stretching. The hinge can be incorporated into any electronic apparatus, for example a portable computer.

  • Patent number: 7791883
    Abstract: A heat exchanger is connected with a heat source in order to dissipate heat generated by the heat source. The fastening apparatus includes a first bracket and a second bracket, both connected to the base, and a first latch element. There is a first opening formed in the first bracket. The first latch element is connected to one side of the heat exchanger, and includes a first protrusion and a first contact section. The first protrusion penetrates through the first opening making the first bracket provide movement limitation to the heat exchanger. The second bracket provides additional movement limitation to the heat exchanger. To separate the heat exchanger from the base, the first contact section is pressed to make the first protrusion move out of the first opening.

    Abstract: A flat radiator with flat type heat pipe and its application for portable computers is provided. The heat pipe in a radiator use tubular type and plate type structures. An air convective extended heat exchange surface surrounds and is over against the fan impeller, such that the radiator is extremely compacted, and the heat transport distance in heat pipe is shortened. Further introducing enhanced convective heat transfer structure and setting the fins according to the aerodynamics improve the heat dissipating capacity. The restrictions to a radiator when installing are reduced, which helps to implement the standardization of the radiator series. Also portable computers using the radiator are provided.

    Abstract: A phase-separated evaporator includes a boiler plate and a phase separation chamber that includes a housing, connected to the boiler plate, having a gas port and a liquid port; and a phase partitioner connected to interiors of the housing, dividing the phase-separated evaporator into a vapor directing compartment and a condensate directing compartment. The phase partitioner includes a partition panel and multiple feeding injectors extending from the partition panel, with the injector tips disposed immediately above the boiler plate. The returning condensate from a condenser enters from the liquid port into the condensate directing compartment and feeds onto the boiler plate through the feeding injectors; while the vapor generated in the vapor directing compartment exits from the gas port, without encountering the condensate.
