  • Patent number: 7824155
    Abstract: A fan holder is provided for holding a fan on a base, wherein the fan holder includes a fixed frame, a movable frame, and a lid. The fixed frame is fixed on the base while the movable frame is pivotally connected to the base, and the movable frame is spaced from the fixed frame by an interval. When the movable frame rotates relative to the base, a containing space is formed between the fixed frame and the movable frame to accommodate the fan. The lid is pivotally connected to an upper edge of the fixed frame, so as to be swiveled relative to the fixed frame for covering the fan, and the lid is engaged with the movable frame simultaneously, so as to holding the fan in the containing space.

  • Publication number: 20100024610
    Abstract: An assembly/disassembly pliers including two pivoted pliers bodies is used to assemble or disassemble a heat sink on or from a chip. The heat sink is disposed in a fixing member, and two hooks of the fixing member are buckled with the chip. An actuating handle and an operating board are respectively disposed on each pliers body, and a bump is extended from at least one operating board. The two actuating handles are actuated to drive the two operating boards to open towards opposite directions, such that the bumps push the fixing member and release the hooks, such that the fixing member and the heat sink are installed on or separated from the chip.

  • Publication number: 20090057524
    Abstract: A fixing assembly is used for fixing a fan having a plurality of fixing holes formed on two ends thereof. The fixing assembly includes a fixed frame, a side plate, a rotatable frame, and a plurality of first vibration absorbing members. The fixed frame is formed by bending a flexible wire for carrying the fan. The side plate is fixed on a board, and the rotatable frame is formed by bending another flexible wire, and is pivoted to the side plate to be opened or clasped on the fixed frame selectively. Each first vibration absorbing member includes a fixed portion fixed in the fixing holes of the fan and an absorbing portion for pressing against the fixed frame or the rotatable frame, so as to fix the fan on the fixed frame or the rotatable frame and absorb or isolate the vibration generated by the fan.

  • Publication number: 20080164011
    Abstract: A liquid cooling type heat-dissipating device for exchanging heat with a heat source is provided, which includes a heat-dissipating fan, a pump, a liquid pipe, a motor, and a heat-dissipating block. The motor drives the heat-dissipating fan and the pump. Two ends of the liquid pipe are connected to the pump so as to form a fluid loop, wherein the liquid pipe is in contact with the heat-dissipating block, and the heat-dissipating block is disposed on the heat source. The liquid pipe is continuously curved on a segment away from the heat-dissipating block to form a curved portion located on a wind output path of the heat-dissipating fan, therefore, the heat-dissipating fan cools the curved portion by blowing wind, so as to increase the speed of temperature dropping thereby improving the heat dissipation performance of the liquid pipe.
