  • Patent number: 7961473
    Abstract: An integrated circuit is disposed on a circuit board. A heat sink retention module includes a bracket, members, and coil springs. The members extend through the coil springs and corresponding holes within the bracket to attach to the board. A heat sink is removably installed within the bracket in a toolless manner, such that the heat sink comes into contact with the integrated circuit. The heat sink and the bracket join together to become a single entity that is permitted to float along an axis perpendicular to a surface of the circuit board. The coil springs are tuned to define a predetermined force at which the heat sink is pushed against the integrated circuit. The module can include a latch having tabs bent at different angles relative to one another to balance forces applied by the tabs against the heat sink while the latter is being installed within the bracket.

    Abstract: Apparatus for securing or retaining a heatsink. The heatsink retention apparatus includes a heatsink module that cooperates with first and second spring loaded latches secure to a circuit board on opposing sides of a heat-generating component. The heatsink module includes a handle pivotally secured to opposing sides of the heatsink body, and bails pivotally secured to the handle. In addition, the bails extend downward to dispose a lower bail member adjacent the spring loaded latches. As the handle pivots between a first position to raise the bails and a second position to lower the bails, the bails automatically move from a locked position to an unlocked position. Each of the spring loaded latches include a hook and at least one pre-loaded spring to transfer a minimum downforce to the lower bail members when the bails are raised. Accordingly, embodiments may be operated from the top of the heatsink without the use of tools, while providing a desired downforce over a range of heatsink heights.

  • Patent number: 7835153
    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.

  • Patent number: 7830665
    Abstract: An easily disassembling cooling apparatus is assembled onto a circuit board. The circuit board has an electronic element. The cooling apparatus includes a pair of fastening blocks, one or two heat conducting blocks, and at least one heat pipe. The pair of fastening blocks are fastened onto the circuit board and each has a track slot and a concave opening. The heat conducting block is installed between the fastening blocks and contacts the electronic element. One end of the heat pipe is assembled with the heat conducting block. The fastening plate is installed in the track slots of the fastening blocks, flexibly wedged in the concave openings, and has a flexible arm that flexibly presses onto the heat pipe or one of the heat conducting blocks. Thereby, the welding process is not required in the assembling process. The assembling time is reduced, and the electronic element is reliably cooled.
