  • Patent number: 7477519
    Abstract: A heat spreading member is received on a predetermined surface of an electronic component. The heat spreading member extends larger than the predetermined surface. A contact piece is contacted with the heat spreading member over a contact area smaller than the predetermined surface. The contact piece serves to realize concentration of an urging force applied to the heat spreading member. The heat spreading member is thus reliably urged against the electronic component. The concentration of the urging force serves to prevent the heat spreading member and the electronic component from camber even if heat is applied to the heat spreading member and the electronic component. Separation is thus avoided between the heat spreading member and the electronic component. The heat spreading member reliably keeps contacting with the electronic component, so that the electronic component package is allowed to enjoy improvement in heat radiation.

  • Patent number: 7468888
    Abstract: A heatsink assembly structure is provided. The heatsink assembly structure includes a heat conducting board attached to a heat-generating element, pressing members fixed to the heat conducting board, and spring plates penetrating through the heat conducting board. A plurality of through holes symmetric about the heat-generating element is formed in the heat conducting board in pairs. Two ends of the spring plates penetrate through the through holes, and are fixed to the pressing members between the through holes. When the spring plates are fixed to the circuit board, the spring plates apply forces that pull the heat conducting board towards the circuit board at positions of the pressing members, so as to push the heat conducting board against the heat-generating element to conduct heat to the heat conducting board. Thus, a plurality of forces pressing the heat conducting board downward is provided with a simple structure.

  • Patent number: 7466548
    Abstract: A cooling device having a heat receiving portion, a heat radiating portion, a heat pipe, and a fan. The heat receiving portion is held on a wiring board and thermally connected to a heat-generating component. The heat radiating portion radiates the heat generated by the heat-generating component, at a position remote from the heat receiving portion. The heat pipe transfers the heat generated by the heat-generating component, from the heat receiving portion to the heat radiating portion. The heat pipe couples the heat receiving portion and the heat radiating portion. The fan applies cooling air to the heat radiating portion. The fan is coupled to the heat radiating portion.

  • Patent number: 7466547
    Abstract: An apparatus for air-cooling an electronic device is disclosed. A contoured panel channels a flow of air within the housing of an electronic device so as to channel the flow of air more directly over heat producing elements such as the microprocessor and peripheral cards. A sensor can also be employed to determine whether the panel is present and properly placed. If not, measures can be taken to reduce the heat generated by the heat producing elements. For example, a warning can be displayed, or the microprocessor can be instructed to enter sleep mode.
