A heat dissipation device includes a heat conductive member, a fin unit coupled to a bottom surface of the heat conductive member and a plurality of LED modules attached to a top surface of the heat conductive member. The heat conductive member consists of a first plate, a second plate parallel to the first plate and a plurality of posts sandwiched between the first and second plates. Peripheries of the first and second plate are in a hermetical conjunction with each other to form a chamber containing a phase-changeable working fluid therein. The first and second plates therein define a plurality of through orifices. The posts each define therein a screwed orifice which is in alignment with corresponding through orifices of the first and second plates respectively and threadedly receives a screw extending through the LED module.

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 fastening device is used for connecting a first and a second fan together. The two fans each have an upper flange and a lower flange and a cylindrical body interconnecting the upper flange and the lower flange. The fastening device includes a plate-shaped pad and two resilient portions respectively extending perpendicularly from two opposite sides of the pad. The two resilient portions respectively extend through the lower flange of the first fan and the upper flange of the second fan, pressing against the first fan and the second fan toward each other. The pad is sandwiched between the lower flange of the first fan and the upper flange of the second fan.

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.

An LED lamp includes a heat sink, a centrifugal blower and a plurality of LED modules. The heat sink includes a base plate defining an air intake adjacent to an end of the base plate and a plurality of fins extending downwardly from a bottom surface of the base plate, between the air intake and an opposite remote end of the base plate. The centrifugal blower is mounted on the bottom surface of the base plate and located between the air intake and the fins. The LED modules are fixed on a top surface of the base plate of the heat sink. The housing engages with the base plate to enclose the centrifugal blower and the fins therein and cooperates with the base plate to define an exhaust port between the opposite remote end of the base plate and a corresponding sidewall of the housing.

A memory module assembly includes a printed circuit board (10) having a heat-generating electronic component (14) thereon, and first and second heat-dissipation plates (20), (30) attached on opposite sides of the printed circuit board. The first heat-dissipation plate includes a first hook (24) extending from a side thereof and the first hook includes a resisting portion (242) extending from an end of the first heat-dissipation plate and a first engaging portion (244) extending from a free end of the resisting portion for resisting the printed circuit board and the second heat-dissipation plate. The second heat-dissipation plate defines a depressed portion (34) in a side thereof for engaging with the first hook. The other sides of the first and second heat-dissipation plates engage with each other to clamp the printed circuit board between the first and second heat-dissipation plates.

An LED module includes a latching component, a frame holding an LED thereon, a heat spreader located in the latching component and a heat transfer member having a heat-dissipating unit remote from the LED and a heat pipe thermally connecting with the heat spreader, the LED and the heat-dissipating unit. The latching component cooperates with the heat spreader to tightly press the frame being attached on the heat spreader. The heat transfer member thermally connects with the heat spreader and transfers heat from the LED to an ambient environment. The latching component has two spring pieces pushing the frame toward the heat spreader and the heat pipe. The spring pieces electrically engage with the frame to thereby electrically connect with the LED.
