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 memory module assembly includes a pair of heat-dissipation plates (10), a printed circuit board (20) sandwiched between the heat-dissipation plates (10), and four clamps (30) for securing the heat-dissipation plates (10) onto opposite sides of the printed circuit board (20). Each clamp includes a connecting portion (32) and a pair of elastic pressing portions (34) extending from opposite free ends of the connecting portion. Each pressing portion has a pair of hooks (342) extending from opposite lateral sides thereof and an engaging portion extending (344) from a free end thereof and clamping on an end of the heat-dissipation plate. The hooks are inserted into openings (18) defined in the heat-dissipation plates and engage with inner surfaces of the heat-dissipation plates.

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 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.

A heat dissipation device includes a heat conducting plate (100) for contacting with an electronic component (400), a heat sink (200) mounted on the heat conducting plate and a heat pipe (300). The heat conducting plate comprises a groove (110) defined in. The heat pipe comprises an evaporating portion (310) sandwiched between the heat conducting plate and the heat sink, and a condensing portion (320) thermally connecting with the heat sink. The evaporating portion comprises a middle portion (3104) having a circular cross section and accommodated in the groove of the heat conducting plate, and a pair of end portions (3102) formed on opposite sides of the middle portion. The end portions have flat bottom surfaces.

A heat dissipating device includes a heat sink (50) and two clips (10) for mounting the heat sink to a retention module (60) which surrounds an electronic component (65). The heat sink provides two shoulders (72). Each clip includes a strap (21) supported on one shoulder, a lever (40) having a cam pivotally connected to the strap, two legs (30) pivotally connected to opposite end portions of the strap, and two spring fingers (26) integrally extending from opposite ends of the strap. In assembly, the straps are downwardly pressed and the retention module push the legs to pivot away from the feet from original states toward forced states. When the legs arrive openings of the retention module the fingers urge the legs to enter the openings. The levers are then pivoted to push the straps to move upwardly to thereby cause the legs to firmly engage in the openings.

A liquid cooling device includes a heat-dissipating unit (1) and a heat-absorbing unit (2). The heat-dissipating unit (1) connects with the heat-absorbing unit (2) by an inlet pipe (4) and an outlet pipe (3) to form a closed circulation loop. The heat-dissipating unit (1) includes a base (10), a tank (20), a heat-dissipating body (30) beside the tank (20) and a cover (40), which are assembled together as a single unit. A pump (23) is placed in the tank (20) and operated to pump liquid coolant to flow in the circulation loop. During flowing through the base (10) and the cover (40), the liquid coolant transfers heat to the heat-dissipating body (30).
