The heat sink fastener includes a heat conductive board and a flexible metallic wire. The heat conductive board has a pair of pivot portions. The flexible metallic wire has a pair of flexible arms and a middle portion connecting therebetween. Each flexible arm connects to the pivot portion. The pivot portion side of the heat conductive board is formed with a blocking sheet. The middle portion is provided with a bend for being blocked by the blocking sheet. When the flexible metallic wire is hooked to a ring on a circuit board, it will generate pressure to the heat conductive board resulting from the bent flexible arms and the blocked middle portion.

An assembled structure of a large-sized LED lamp includes a substrate. One surface of the substrate is provided with a plurality of LED modules. Each LED module comprises a circuit board and a plurality of LEDs fixedly connected to the circuit board. A lamp mask is locked onto the substrate to cover and protect the LED modules. A sealing material is provided between the lamp mask and the substrate to protect the permeation of liquid. Further, at the positions of the other surface of the substrate, heat-dissipating modules are provided to correspond to each LED module, respectively. The heat-dissipating modules are used to dissipate heat generated from the LEDs. A lamp cover is covered to the exterior of the heat-dissipating modules. The lamp cover is locked onto the substrate. With the modulization of each constituent element, the detachment, assembly and repair of the present invention can be much simpler and more convenient.

An integral heat dissipating device includes a radiating plate, a fan blade and a cover. The radiating plate has a heat dissipating channel. A fan blade receiving chamber is communicated with the heat dissipating channel and a heat conductive plate is connected to the bottom of the outer wall of the heat dissipating channel. The bottom of the fan blade receiving chamber is installed with an axial hole which serves to be installed with a fan blade. The axial hole can be installed with a fan blade with power. An inclined surface is formed at the upper side of the fan blade receiving chamber. A plate shape heat tube is welded between the heat conductive plate and the bottom of the heat dissipating channel. A plurality of screw retaining posts capable of being screwedly fixed to a circuit board being suspended from the lateral side of the heat conductive plate. The cover is a thin plate with a hole for sealing the upper side of the heat dissipating channel and the fan blade receiving chamber. The hole is placed above the fan blade receiving chamber for being formed as a tilt wind opening. In the present invention, the radiating plate is made integrally and can be directly connected to the fan. The shape of the heat conductive plate may include with a heat dissipating element as required. The heat conductive glue adheres to a heat conductive medium for achieving the object of high heat dissipation and low cost.

A flow channel type heat dissipating fin set is formed by a plurality of metal pieces. Each metal piece comprises a body; and a connecting piece installed on the body having one or more connecting pieces punched from the body; the connecting piece being protruded from one side of the body; a via hole being formed on the body; and buckles and buckling holes being formed on the body. The metal pieces are combined by buckling the buckles and buckling holes so that the metal pieces are continuously buckled and stacked as a heat dissipating fin set; and via holes on the bodies of the metal pieces are formed as longitudinal flow channels. Thus, a flow channel type heat dissipating fin set is formed.
