Sheet-combined thermal-dissipating device

Abstract

A sheet-combined thermal-dissipating device has a plurality of thermal-dissipating sheets, which are connected with each other. Each of the thermal-dissipating sheets includes a connecting portion, at least one thermal-dissipating fin and a plurality of sub-thermal-dissipating fins. The connecting portions of the thermal-dissipating sheets are connected with each other. The thermal-dissipating fin is extended outwardly from the connecting portion, and the thickness of the connecting portion is greater than that of the thermal-dissipating fin. The sub-thermal-dissipating fins are extended outwardly from at least one side of the thermal-dissipating fin.

       10 . The sheet-combined thermal-dissipating device of  claim 1 , wherein the shapes or sizes of adjacent two of the thermal-dissipating sheets are the same or different. 
   
   
       11 . The sheet-combined thermal-dissipating device of  claim 1 , wherein the sub-thermal-dissipating fins and the adjacent sub-thermal-dissipating fins are disposed alternately. 
   
   
       12 . The sheet-combined thermal-dissipating device of  claim 1 , wherein the sub-thermal-dissipating fins touch against the adjacent sub-thermal-dissipating fins so that the thermal-dissipating fins expand outwardly from each other. 
   
   
       13 . A sheet-combined thermal-dissipating device having a plurality of thermal-dissipating sheets, each of the thermal-dissipating sheets comprising:
