US 7088582 B2Abstract
The present invention is to provide a heat-dissipating device comprising a sheet formed thereon with a plurality of first parts and a plurality of second parts, wherein any one of said second part is disposed between any two of said first parts, and the junction therebetween is bent with an angle enabling the ends of two adjacent first parts distal to the second part to be connected with each other. As a result, the second parts form corresponding parallel plates respectively on each side of a heat-dissipating device for being placed on a heat-source to dissipate heat transmitted therefrom, and the first parts act as the supporting plates for supporting the parallel plates.
The object of the present invention is to provide a heat-dissipating device comprising a sheet formed thereon with a plurality of first parts and a plurality of second parts, wherein any one of said second part is disposed between any two of said first parts, and the junction between every two adjacent first part and second part is bent with an angle enabling the ends of two adjacent first parts distal to the second part to be connected with each other. As a result, the second parts act as two corresponding parallel plates respectively on each side of a heat-dissipating device, and the first parts then act as the supporting plates for supporting the parallel plates. Therefore, while one side of the heat-dissipating device is placed on a heat-source, heat dissipated from the heat-source can be transmitted to the heat-dissipating device to be distributed to the outer environment, which protects the heat-source from damage owing to the over heat.
FIG. 1 is a perspective view of the conventional heat-dissipating device;
FIGS. 2 and 3 show one embodiment according to the present invention, which relates to a heat-dissipating device made by a metal sheet 2 being bent to form a plurality of first parts 20 and a plurality of second parts 22, wherein at least one of the second parts 22 is disposed between two adjacent first parts 20. The junction between the first part 20 and the second part 22 is bent with an angle enabling any two adjacent first parts 20 to be connected with each other at the corresponding ends distal to the second part 22. As a result, any two adjacent second parts 22 act as two corresponding parallel plates 30 of a heat-dissipating device 3, and the first part 20 therebetween acts as a supporting plate 32 of the heat-dissipating device 3 for supporting the two parallel plates 30 adjacent thereto. Therefore, adjacent sections of the heat-dissipating device 3 are composed of two parallel plates 30 along with two supporting plates 32 therebetween. While the parallel plates 30 on one side of the heat-dissipating device 3 are in contact with a heat-source, such as a central processing unit of a computer, heat dissipated from the heat-source can be transmitted to the supporting plates 32 and through the supporting plates 32 to the parallel plates 30 on another side thereof for distributing the heat to the outer environment to protect the heat-source from damage due to over heat. Besides, since any two adjacent first parts 20 of the heat-dissipating device 3 are connected at the corresponding ends for supporting with each other, two adjacent first parts 20 strengthen the structure of the heat-dissipating device 3 not easily being crushed by the force acted thereon. Further, the fabrication of the heat-dissipating device 3 directly utilizes stamping and bending skills to form the structure thereof on the metal sheet, which is more convenient than the fabrication of the conventional method via pre-producing a plurality of U-shaped heat-dissipating sheets and then composing a certain amount of the U-shaped heat-dissipating sheets to form the required heat-dissipating device. Besides, the fabrication of directly bending the metal sheet to form the heat-dissipating device according to the present invention significantly minimize the amount of wasted raw materials being produced than the conventional method.
