A liquid-cooling heat sink includes a base (10), a heat exchanger (30), a housing (20), an inlet (26) and an outlet (27). The heat exchanger (30) has a hollow (33) formed therein, and is thermally coupled to the base (10). The housing (20) has a chamber (24) formed therein, and is placed over the base (10). The chamber (24) is separated by the heat exchanger (30) into a first sub-chamber (241) and a second sub-chamber (242). The first sub-chamber (241) is in fluid communication with the second sub-chamber (242) through a plurality of microchannels (32) radially formed within the heat exchanger (30). The inlet (26) is fluidly connected to the first sub-chamber (241) so as to impinge liquid coolant to a top surface of the base (10).

A gas-liquid separation apparatus includes an inlet pipe for transferring liquid with gas dissolved therein and a separating pipe for separating the gas from the liquid. The separating pipe has a spiral-shaped guiding member therein. The separating pipe extends from the inlet pipe and is in alignment and communicating with the inlet pipe. An outlet pipe extends from a joint of the inlet pipe and the separating pipe and communicates with the separating pipe, for transferring therein the liquid after the liquid has been degassed by the spiral-shaped guiding member in the separating pipe. A gas storage device communicates with the separating pipe and outside for collecting the gas from the separating pipe and discharging the gas to the outside.

A memory module assembly includes a printed circuit board (30) having a heat-generating electronic component (32) thereon, a heat sink (10) and a clip (20) for securing the heat sink onto the heat-generating electronic component. The heat sink includes a base (12) and a plurality of fins (14) arranged on the base. A plurality of recesses is defined in the heat sink. The clip includes a body (22) resting against a face of the printed circuit board and elastic hooks (24) extending from the body. The hooks are received in the recesses and resiliently press the base of the heat sink toward the heat-generating electronic component, whereby the clip clamps the heat sink and the printed circuit board together.

A miniature pump in accordance with the present invention comprises a pump casing (10) and a liquid circulating unit (20) received in the pump casing. The pump casing comprises a hollow main body (14) transversely forming a spacing plate (126) and a partition wall (144) spaced from the spacing plate. The liquid circulating unit comprises a shaft (25) mounted between the partition wall and the spacing plate, a bearing (27) rotatably mounted the shaft, an impeller (26) attached to the bearing, a first pair of spaced magnetic spacers (21,22) surrounding an upper portion of the shaft and positioned above the bearing, and a second pair of spaced magnetic spacers (23, 24) surrounding a lower portion of the shaft and positioned below the bearing. The two pairs of magnetic spacers properly suspend the impeller in a stable position in an axial direction of the pump when the impeller rotates.

A locking device (100) used for securing a heat sink (10) to a heat-generating component in accordance with an embodiment includes a pair of retainers (20). The locking device cooperates with a retention frame (30) to secure the heat sink to the heat-generating component. Each retainer (20) includes a handle (22) and a locking leg (24). The handle is pivotably mounted to fins of the heat sink via a pivot (225). The locking leg is made from a unitary sheet member and is connected to the handle at a location spaced apart from the pivot via which the handle is mounted to the heat sink. When the handle is brought to pivot about the pivot, the locking leg is driven to move in a direction to engage with the retention frame whereby the heat sink is firmly secured to the heat-generating component.
