Abstract: A thermal module (10) includes a fin assembly (14), a heat pipe (16) thermally contacting with a heat generating electronic component (60) disposed on a printed circuit board (50) and the fin assembly, and a resilient fastener (20) attaching an evaporation section (164) of the heat pipe to the heat generating electronic component. The fastener includes a mounting element (40) being attached to the printed circuit board, and an engaging element (30) embedded in the mounting element. The engaging element includes a base plate (32) having a first surface contacting with the evaporation section of the heat pipe and a second surface thermally contacting with the heat generating electronic component, and at least a resilient strip (34) sandwiched between the first surface of the base plate of the engaging element and the mounting element.

Abstract: A heat dissipation module for removing heat from a heat-generating electronic component includes a base (106) and a clip (40, 40a). The clip includes a connecting arm (42, 42a) and a securing arm (44, 44a) for locking the base to the heat-generating electronic component. The connecting arm engages with the base. The securing arm extends from the contacting arm and is curve-shaped with a free end thereof being for being depressed whereby the securing arm exerts a downward force on the base so that the base and the electronic component can have an intimate contact with each other.

Abstract: An electronic assembly includes a casing (10) of an electronic product, and a thermal module disposed in the casing. The casing has a sidewall (102) defining a plurality of slots (1011) therein. The thermal module includes a centrifugal blower (50), a fin assembly (40) and a plurality of sub-fins (701). The centrifugal blower defines an air outlet (502) therein. The fin assembly is disposed at the air outlet of the centrifugal blower and includes a plurality of fins (401) and has a plurality of air passages (402) formed between adjacent fins. The sub-fins are located between the fin assembly and the sidewall of the casing, and forming a plurality of air channels (702) therebetween. The air channels of the sub-fins communicate the air passages of the fin assembly with the slots of the sidewall of the casing.

Abstract: A thermal module (10) includes a chassis (11) of an enclosure of an electronic device, a fin assembly (13) and a centrifugal blower (14) for producing an airflow flowing through the fin assembly. The centrifugal blower includes a housing (141), and the housing is integrally formed with the chassis as a monolithic piece. A U-shaped heat pipe (16) extends through the housing and has a condensing section (161) thermally connecting with the fin assembly and an evaporating section (162) attached to a heat spreader (12) for thermally connecting with a heat generating electronic component.

Abstract: A heat dissipation device includes a heat sink (10) and a blower (50) for generating an airflow to the heat sink. The blower includes a housing (60) and at least one plate (63a, 63b) extending outwardly from the housing. The housing forms a contacting surface (610, 620) abutting a side of the heat sink. The plate includes an inner surface (630) abutting another side of the heat sink. A groove (69) is defined in a junction of the housing and the plate, and thus the contacting surface of the housing and the inner surface of the plate are planar-shaped to avoid interference between the housing of the blower and the heat sink. The groove has chamfer angles R therein. The housing is made by plastic injection molding or die casting.

Abstract: A thermal module (10) for dissipating heat from a heat-generating electronic component (20) includes a base plate (11), a heat-dissipating fan (16) mounted to one side of the base plate, at least a heat pipe (12) mounted to another side opposite to the one side of the base plate, and a fin assembly (14) mounted to an air outlet of the heat-dissipating fan. The heat pipe includes a bending portion (124). The fin assembly includes a portion (142) corresponding to the bending portion of the heat pipe. The fins of the portion of the fin assembly are arranged along an extension direction of the bending portion of the heat pipe.
