Abstract:
A heat sink having heat-dissipating fins capable of increasing heat-dissipating area-includes a heat pipe and the heat-dissipating fins. The heat pipe has a heat-absorbing section and a heat-releasing section. The heat-dissipating fin has a lower plate and an upper plate. The upper plate is bent to be overlapped on the lower plate, thereby forming a heat-dissipating path (b) therebetween. The lower plate and the upper plate are provided with a through-hole respectively in such a manner that these two through-holes correspond to each other. The heat-releasing section of the heat pipe penetrates the through-holes of the heat-dissipating fins successively. In this way, the heat-dissipating area in the same height can be increased, thereby improving the heat-dissipating efficiency of the heat sink.
Abstract:
The present invention relates to a heat sink of a large area, in which a heat-dissipating body is further provided in its limited space. The method for manufacturing a fin includes the steps of providing a fin, cutting the fin to form a foldable piece thereon, folding back the foldable piece to be overlapped on the fin and form an accommodating hole, and punching the folded piece and the fin to form two overlapped through-holes. The fin, the heat-dissipating body and heat pipes are assembled together to obtain the heat sink. Since the fins and the heat-dissipating body dissipate the heat of a heat-generating element simultaneously, the heat-dissipating efficiency of the heat sink can be improved.
Abstract:
A heat dissipating structure of an LED circuit board includes an LED circuit board having a plurality of soldering points. The soldering points of the LED circuit board are covered by a coating layer including Nanoparticles and a bonding agent. The coating layer has the characteristics of high emitting rate, temperature resistance, and conductivity insulation. On the other hand, the coating layer can increase the contacting areas of the soldering points with the air to enlarge the heat dissipation area of the LED circuit board. The LED circuit board covered by the coating layer is placed in an LED lamp tube to provide good heat dissipation effect.
Abstract:
A heat conducting structure, a heat sink with the heat conducting structure, and a manufacturing method of the heat conducting structure are disclosed. The manufacturing method includes the steps of providing a first mold (20) and a second mold (30) having different concave cambers (211, 211a, 221, 221a), using the first mold (20) to progressively compress the heat pipes (10) and form a camber (112) at an evaporating section (11), using the second mold (30) to compress the camber (112) to form a contact plane (112′) and an attaching plane (113′) perpendicular to each other, coating an adhesive (50) on the contact planes (112′), connecting the contact planes to make the attaching planes co-planar.
Abstract:
A heat pipe assembly includes a number of heat pipes and a fixing seat. Each of the heat pipes includes an evaporating section and at least a condensing section. A bottom of the evaporating section of each of the heat pipes is flat and has a flat heat absorbing surface. The evaporating sections of each of the heat pipes are parallel to and adjoin with each other, whereby the flat heat absorbing surfaces of the evaporating sections of the heat pipes being coplanar and adjoining with each other. A top surface of the evaporating section of each of the heat pipes has a top edge. The fixing seat, as a molded one-piece member, combines with the top edge of the evaporating section of each of the heat pipes, whereby the heat absorbing surfaces of the evaporating sections of the heat pipes are coplanar and adjoin with each other.
