A method for forming the unit is included.
Abstract:
The heat sink of the invention includes a cylinder and fins fastened thereto. A hollow in the cylinder is for receiving a heat source. Each the fin includes two parallel wings and a connection plate therebetween. A space is defined by the two wings and the connection plate for air flow.
Abstract:
A heat sink composed of a fin set and a seat and a method for manufacturing the same are disclosed. One side of the seat is provided with a plurality of rail rods whose cross sections are of a hook shape. One side of the fin set is formed with a plurality of slots corresponding to the rail rods. Thus the fin set and the seat can be assembled by engagement of the rail rods and slots. A press mold is employed to press the rail rods, thus the rail rods are deformed to make the fin set and seat tightly engage with each other.
Abstract:
In an embodiment of the invention, a slot is disposed at a side of a fin. Both sides of the slot separately extend two positioning portions. After a heat pipe is placed in the slot, a mold presses the fin to make the positioning portions bent inwards. The heat pipe is gripped by the deformed positioning portions. In another embodiment, peripheries of the positioning portions are formed into guiding grooves separately, and the mold is provided with two protrusions corresponding to the guiding grooves. The guiding grooves are inserted by the protrusions when the mold is pressing the fin. The part between the positioning portions and slot is inwards deformed to grip the heat pipe.
Abstract:
A method for connecting heat pipes and a heat sink comprises the steps of drilling a set of through holes through a heat dissipating base slab, implanting heat pipes through the through holes, integrating the heat-dissipating base slab with the heat pipes by punching using a press machine, and bending and twisting the heat pipes according to a predetermined angle and shape, whereby a set of radiation fins will be connected. The heat radiating device thereby produced is used on electronic elements.
Abstract:
In a heat dissipating device holder structure with a thin film thermal conducting medium coating, at least two thermal conducting medium coating blocks are set on attaching surfaces of a heat dissipating device holder and a processor, and a gap is disposed between the coating blocks, such that when the heat dissipating device holder is attached to the processor, the compressing force of the heat dissipating device holder and the processor exerted onto the thermal conducting medium coating blocks can be spread to fill the spread thermal conducting medium into a short distance of the gap, so as to achieve the best thin film coating for the thermal conducting medium and effectively lower thermal resistance and attach the heat dissipating apparatus holder tightly with the processor for the best heat dissipation effect.
Abstract:
A method for riveting fins into a bottom plate of a heat dissipating device is disclosed. A punching device has a plurality of weights each of which is formed as a thin sheet. The punching device is installed to a fixture; a plurality of fins are spaced with a predetermined gap; and a bottom plate is formed with a plurality of trenches for receiving the fins. The method comprising the step of: positioning the bottom plate at the fixture; inserting the fins into the trenches of the bottom plate; inserting the weights of the punching device into the fins so that each space between two fins has a weight; and punching a backside of the bottom plate by a puncher so that as the bottom plate moves; the weights collides portions of the bottom plate between the fins to deform and rivet the fins into the bottom plate; and thus the fins are firmly secured in the bottom plate.
Abstract:
A heat-dissipating device with heat conductive tubes comprises a heat-dissipating unit having plurality of fins; each fin having a plurality of through holes; each through hole having a corresponding via hole near the through hole; a plurality of annular walls being arranged around each through hole; and a plurality of heat conductive tubes passing through respective through holes of the fins. In manufacturing, the plurality of heat conductive tubes and the heat-dissipating unit with press bars are positioned to a fixture; a shaping mold serves to punch the press bars so that the press bar to press the side walls and thus the fins are tightly riveted to the heat conductive tubes.
Abstract:
The lamp seat structure includes an annular seat and a frame. The annular seat is composed of a cylinder and a plurality of fins radially disposed on an outer surface of the cylinder, in which each of the fins has an engagement protrusion. The frame is formed with a flange. The frame is assembled with the annular seat by engaging the flange with the engagement protrusion, and the engagement protrusion is deformed by the flange to fasten each other.
