Abstract: A heat sink fixing device has an enclosing frame socket having a central part for disposing a heat generating unit of an electronic device thereon, with a heat sink mounted on the enclosing frame socket and covering the heat generating unit. A first fixing part is provided on a bottom surface of the heat sink, and a second fixing part corresponding to the first fixing part of the heat sink is provided on the enclosing frame socket, allowing the heat sink to be coupled to the frame socket by coupling the first fixing part of the heat sink with the second fixing part of the frame socket, thereby substantially maximizing heat dissipating area on the heat sink.

Abstract: A radiator structure includes a radiator frame, a radiator and a plurality of elastic latch members. The radiator frame is mounted onto a main board corresponding to an electronic element, and has a plurality of coupling sections and an opening corresponding to the electronic element and the surface of the electronic element exceeds its peripheral edges. The radiator is mounted on the radiator frame in contact with the surface of the electronic element, and has a plurality of latch sections corresponding to the coupling sections. The elastic latch member coupled on the latch section is bent to form a force applying section, a latch arm and a swinging arm. After the force applying section receives a force, the swinging arm coupled on the latch section is turned to enable the latch arm to latch on the coupling section thereby to anchor the radiator on the radiator frame to disperse heat.

Abstract: A heat sink mount including a body, a first operating member, and two second operating members is provided. The body is formed with a first side, a second side opposite to the first side, a third side connecting the first side and the second side, and a fourth side opposite to the third side and connecting the first side and the second side. One end of the first operating member is pivotally attached to the first side of the body, and the other end thereof is rotatably coupled to the second side of the body. The first operating member further includes a second positioning portion and a third positioning portion. Each of the second operating members is pivotally attached to the third side and the fourth side of the body respectively and fixed in position by the second positioning portion and the third positioning portion respectively.

Abstract: A radiation board consists of a case and a lid. The case has a plurality of circulation channels formed on an inner wall. The lid seals the case to confine an operation fluid in the circulation channels of the case. The lid has miniature flutes corresponding to the circulation channels. Heat generated by a heat-generating element during operation is transferred through the lid to the operation fluid to vaporize the operation fluid. The miniature flutes help to condense the vaporized operation fluid into a liquid again. The operation fluid circulates in the case through the circulation channels to evenly distribute heat to the entire device. The radiation board is easy to fabricate at a low cost.

Abstract: A fan assembly includes a metal frame, a vane, and a driving means; wherein the driving means is installed at the middle of the metal frame and the vane is installed at an end of the driving means. With better tensile strength and structural strength of a metal, the thickness of the metal frame of the fan assembly can be made thinner, and thus improving the airflow and the heat dissipating effect to dissipate produced heat more effectively.

Abstract: A closed loop heat dissipation apparatus includes a heat transfer seat containing an operation fluid, a seal lid attaching to a heat generating element and sealing one side of the heat transfer seat to hold the operation fluid therein, a tube made of flexible metal to couple on the heat transfer seat in a bendable manner and a radiation fin assembly mounted on the tube. The operation fluid absorbs the heat energy of the heat generating element and circulates in the tube to evenly distribute the heat energy, and is condensed to liquid phase to flow back to the heat transfer seat. The apparatus may be fabricated at a lower cost and achieve an improved heat dissipation effect.
