Abstract: A heat sink assembly includes a heat sink (10), a mounting frame (20) for mounting the heat sink to an electronic component (60), and a grease cover (40). The heat sink includes a base (12) on which thermal grease (16) is spread. The mounting frame includes a body (22) defining an opening (24) for extension of the electronic component therethrough to contact the base. The body includes longitudinal and lateral beams (25, 27) surrounding the electronic component. A plurality of fasteners (26) is formed on the longitudinal beams and engaged in cutouts (16) defined in the base, respectively. The grease cover is detachably attached to the mounting frame, and includes a main portion (42) covering the opening of the mounting frame and the thermal grease, and an ear (44) extending from the main portion beyond one border of the mounting frame for facilitating operation of the grease cover.

Abstract: A method of combining fins (30) with heat pipe (20) includes the following steps: have a hole (34) defined on each fin, a turnup flange (36) is drawn from the hole, and a slit (38) is lengthways defined on the turnup flange; mounts the fins on the heat pipe with the turnup flanges enclosing the heat pipe; fills solder into the slit of each fin; put the fins and the heat pipe under high temperature to heat up; and takes the fins and the heat pipe out.

Abstract: A mounting device (20), for mounting a heat sink (10) to a circuit board (50) on which an electronic component (60) is mounted, includes a body (22). The body includes an opening (24) for extension of the electronic component to contact the base and a plurality of longitudinal and lateral beams (25, 27) surrounding the electronic component and being sandwiched between the base and the circuit board. A plurality of fasteners (26) is formed on a top face of the longitudinal beams and engaged in cutouts (16) defined in the base, respectively. A pair of latches (32) is formed on a bottom face of the longitudinal beams and engaged in a pair of locking sots (54) defined in the base, respectively. Four pairs of feet are formed on four corner portions of a bottom face of the body and are received in locating openings of the circuit board, respectively.

Abstract: A heat sink assembly includes a fan (10), two fixing members (20), a heat sink (30), and a plurality of screws (40, 50). The fan is generally parallelepiped, and defines four mounting holes (102) in corners thereof. Each fixing member has a first plate (202) defining a pair of first fixing holes (212), and a second plate (204) extending perpendicularly from a top edge of the first plate. An ear (203) defining a second fixing hole (214) corresponding to one of the mounting holes of the fan extends from each of opposite ends of the second plate. A pair of locking holes (302) is defined in a top portion of an outmost fin (304) at each of opposite sides of the heat sink, corresponding to the first fixing holes of one of the fixing members. The fan, the fixing members and the heat sink are fastened together by the screws.
