A heat sink for cooling an electronic component includes a lower plate, an upper plate, an upper fin set and a lower fin set respectively fixed on the upper plate and the lower plate, and a plurality of heat pipes sandwiched between the upper plate and the lower plate. The lower plate forms a protrusion projecting downwardly therefrom. A bottom surface of the protrusion is milled to be flat and smooth, whereby the bottom surface can intimately contact the electronic component. A method for manufacturing the heat sink comprising milling a bottom surface of a protrusion punched downwardly from a lower plate, whereby the bottom surface can be flat and smooth sufficiently to have an intimate contact with an electronic component, and sequentially welding an upper plate on the lower plate and a plurality of fins on the lower plate and the upper plate, respectively.

A miniature liquid cooling device includes a casing (10) having a base (16) attached on a heat-generating electronic component for absorbing heat generated by the electronic component. The casing includes an outer wall (12) mounted on the base and a top cover (15) mounted on the outer wall. A receiving space is enclosed by the casing. A heat-absorbing member (40) is attached on the base and received in the receiving space for exchanging heat with liquid in the casing. An impeller (21) is rotatably mounted in the receiving space and above the heat-absorbing member. When the impeller rotates the liquid is driven to flow into the liquid cooling device via a liquid inlet (122) and then flow through the heat-absorbing member and finally flow out of the liquid cooling device via a liquid outlet (124).

A liquid cooling device includes a base, a housing and a heat exchanger. The base and the housing enclose a chamber which receives the heat exchanger therein. Inlet and outlet for liquid are provided at the housing. The heat exchanger includes stacked flakes. Each flake includes parallel and alternately arranged first and second strips each having a void defined therein. The flakes are stacked in a manner such that each first strip overlays and abuts against a corresponding second strip of an adjacent flake and that the void in each first strip and the void in the corresponding second strip of the adjacent flake are in fluid communication with each other to thereby form a channel between the inlet and the outlet.

A vapor chamber includes a base (100) for contacting a heat-generating component (500), a cover (200), a first porous capillary sheet (300) located in the base and a second porous capillary sheet (400) located in the cover and facing the first porous capillary sheet. The base comprises a block (130) extending from the base to thermally connect with the cover. The cover is mounted on the base and forms a hermetically sealed container together with the base. The first and second porous capillary sheets together form an enclosure and are contained in the container, and the block extends through the first and second porous capillary sheets and engage therewith.

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.
