A memory module assembly (1) includes a printed circuit board (30) having an electronic heat-generating component (40) thereon, a heat sink (20) and a clip (10) for securing the heat sink onto the heat-generating component mounted on the printed circuit board. The heat sink includes a base (22) and a plurality of fins (24) arranged on the base. A recess (28) is defined extending across the fins. The clip includes a retaining portion (12) resting against a face of the printed circuit board opposite the heat sink and an elastic pressing portion (16) spaced from the retaining portion. The pressing portion is received in the recess of the heat sink and resiliently presses the base of the heat sink toward the heat-generating component, whereby the clip clamps the heat sink and the printed circuit board therebetween.

A liquid cooling system includes a cooling body (1) defining an hollow portion receiving a pump (3) and a number of cooling fins (18) therein, and a contact portion for contacting an electrical component. The cooling body defines a passageway therein filled with liquid coolant, and an inlet (124) and an outlet (125) both in communication with the passageway. The pump defines an exit (31) and an entrance (32) connected to the inlet and the outlet of the cooling body respectively by two tubes (5). Heat is transferred from the electrical component to the contact portion, and then conducted to the coolant, and conducted to other portions of the cooling body as the coolant flows through the passageway. The heat is then conducted to the cooling fins for dissipation.

A heat sink clip comprises a connecting member (12), two pressing members (14) connecting to the connection member, each of the pressing members comprising a pressing portion (141) and two spring portions (142, 143) extending from opposite ends of the pressing portion, a first locking portion (144) depending from one of the spring portions of each pressing member, two operating members (16) each having spaced first and second pivot means, the second pivot means being below the first pivot means, the operating members respectively pivotably connected to the other one of the spring portions, and two second locking portions (18) respectively pivotably connected to the operating members. When the operating members are rotated downwardly, the first and second locking portions are raised, adapted for engaging with a retention frame and securing a heat sink to an electronic package.

An operating device (10) for detaching a heat sink (40) from a heat-generating electronic device (30) includes a bracket (12) and four handles (14) rotatably connected to the bracket. The bracket includes a pair of first beams (16) and a pair of second beams (18). The second beams perpendicularly connect with the first beams. An opening (21) is thereby defined in a central section of the bracket. A pair of symmetrically opposite pivots (20) extends from each end of each first beam. The handles each include an operating portion (22), and a pressing portion (24) perpendicular to the operating portion. A pair of pivot holes (26) is defined in two junctions of the operating portion and the pressing portion, pivotably receiving corresponding pivots of the bracket.

A heat sink clip assembly for attaching a heat sink (30) to a CPU (40) mounted to a motherboard (50) includes a rigid shaft (10) and two wire clips (20). The shaft includes a pressing section (12) for pressing the heat sink, two engaging sections (14) at opposite ends of the pressing section, and two stop sections (16) at outmost ends of the engaging sections. A diameter of the engaging sections is less than diameters of the pressing section and the stop sections. Each wire clip has a coiled portion (22), and two spring arms (24) extending from opposite ends of the coiled portion. Each spring arm extends perpendicularly to a central axis of the coiled portion. A hook (26) is formed at a distal end of each spring arm, for engaging with a corresponding through hole (52) of the motherboard. The heat sink is thereby attached to the motherboard.

A fastener (50) includes a pin (52), a spring (54) and a handle (56). The pin extends through a heat sink (10). The handle is pivotably attached to a top portion of the pin. The pin has a foot (522) extending through a mother board (30) and a supporting board (40) located under the mother board to engage with the supporting board. A CPU (20) is mounted on the mother board. The spring surrounds the pin and is located between a base of the heat sink and the handle. When the handle is rotated from a horizontal position to a vertical position, the handle compresses the spring toward the foot. The spring in turn presses the base of the heat sink against the CPU.
