Abstract: A heat dissipation device includes a heat sink (10) and a blower (50) for generating an airflow to the heat sink. The blower includes a housing (60) and at least one plate (63a, 63b) extending outwardly from the housing. The housing forms a contacting surface (610, 620) abutting a side of the heat sink. The plate includes an inner surface (630) abutting another side of the heat sink. A groove (69) is defined in a junction of the housing and the plate, and thus the contacting surface of the housing and the inner surface of the plate are planar-shaped to avoid interference between the housing of the blower and the heat sink. The groove has chamfer angles R therein. The housing is made by plastic injection molding or die casting.

Abstract: A thermal module (10) for dissipating heat from a heat-generating electronic component includes a fin assembly (12), and a heat pipe (14) including an evaporator section (141) and a curve shaped condenser section (142). The evaporator section of the heat pipe thermally contacts with the heat-generating electronic component, and the condenser section of the heat pipe is disposed on the fin assembly along a longitudinal axis of the fin assembly. The condenser section has a serpentine configuration.

Abstract: A fastening device (10) for mounting a first member (12) to a second member, the fastening device includes base member (14) and a resilient spring member (15). The base member includes a contacting plate (141) contacting with the second member, and a receiving channel for (147) receiving a portion of the first member therein. The resilient spring member includes two ends for being attached to a board with the second member mounted thereon, and a middle portion contacted with the first member to sandwich the first member between the second member and the spring member.
