Abstract: A heat-dissipating apparatus is installed on a circuit board which includes a board body formed with a plurality of apertures, a heat-generating element, and a lock member having an engaging hole. The heat-dissipating apparatus includes a base plate and a plurality of fastening elements. The base plate is abutted against the heat-generating element, and includes an engaging hook for engaging the engaging hole, and a plurality of through holes corresponding in position to the apertures. A plurality of connecting elements are disposed below the board body and correspond in position to the apertures. Each fastening element extends through a respective through hole, and is engaged to a respective connecting element after extending through a respective aperture. A plurality of spring members are respectively sleeved on and bias the fastening elements to move away from the base plate.

Abstract: A noise elimination apparatus for a radiator allows an elastic cushion to shield a plurality of screw holes on a upper cover to enable air flow driven by a fan not to be expelled out through the screw holes; an elastic blocking plate is combined with the radiator at an inner side of an exhaust thereof; the blocking plate shields a gap between a bottom portion of an opening at an inner side of a scooper to cause air flow expelled via the exhaust of the radiator not to be expelled through the gap mentioned above. Whereby, wind shear sound and annoying high frequency noise generated when the fan is working can be reduced.

Abstract: In an assembly of a heat-dissipating device and a circuit board, the circuit board has a heat-generating component and is formed with board holes. The heat-dissipating device includes a base plate, a heat-dissipating component, fastening members, biasing members, engaging members, and resilient washers. The base plate abuts against the heat-generating component, and is formed with through-holes. The heat-dissipating component is disposed on the base plate. Each fastening member has a shank part extending through one through-hole and one board hole, a head part, and a threaded connection part. Each biasing member abuts against the base plate and the head part of one fastening member. Each engaging member is disposed at a lower surface of the circuit board and engages the threaded connection part of one fastening member. Each washer is sleeved on one fastening member, and abuts against an upper surface of the circuit board.
