Heat dissipation base seat

Abstract

A heat dissipation base seat includes a main body. A first extension arm, a second extension arm, a third extension arm and a fourth extension arm respectively extend from four corners of the main body. Two first bent sections respectively extend from two sides of the first extension arm. Two second bent sections respectively extend from two sides of the second extension arm. Two third bent sections respectively extend from two sides of the third extension arm. Two fourth bent sections respectively extend from two sides of the fourth extension arm. At least one locating hole is formed at a free end of each of the first, second, third and fourth extension arms, which free end is distal from the main body. By means of the first, second, third and fourth bent sections, the structural strengths of the extension arms are greatly increased.

What is claimed is: 
     
         1 . A heat dissipation base seat comprising a main body, a first extension arm, a second extension arm, a third extension arm and a fourth extension arm respectively extending from four corners of the main body, two first bent sections respectively extending from two sides of the first extension arm, two second bent sections respectively extending from two sides of the second extension arm, two third bent sections respectively extending from two sides of the third extension arm, two fourth bent sections respectively extending from two sides of the fourth extension arm, at least one locating hole being formed at a free end of each of the first, second, third and fourth extension arms, which free end is distal from the main body. 
     
     
         2 . The heat dissipation base seat as claimed in  claim 1 , wherein the first, second, third and fourth bent sections are formed on long sides of the first, second, third and fourth extension arms. 
     
     
         3 . The heat dissipation base seat as claimed in  claim 1 , wherein the first bent sections have a first folded edge and a second folded edge disposed on two sides of the first extension arm respectively, the first and second folded edges respectively inward extending from outer sides of the first extension arm toward each other. 
     
     
         4 . The heat dissipation base seat as claimed in  claim 1 , wherein the second bent sections have a third folded edge and a fourth folded edge disposed on two sides of the second extension arm respectively, the third and fourth folded edges respectively inward extending from outer sides of the second extension arm toward each other. 
     
     
         5 . The heat dissipation base seat as claimed in  claim 1 , wherein the third bent sections have a fifth folded edge and a sixth folded edge disposed on two sides of the third extension arm respectively, the fifth and sixth folded edges respectively inward extending from outer sides of the third extension arm toward each other. 
     
     
         6 . The heat dissipation base seat as claimed in  claim 1 , wherein the fourth bent sections have a seventh folded edge and an eighth folded edge disposed on two sides of the fourth extension arm respectively, the seventh and sixth folded edges respectively inward extending from outer sides of the fourth extension arm toward each other. 
     
     
         7 . The heat dissipation base seat as claimed in  claim 1 , wherein the first bent sections have a first folded edge and a second folded edge and a first recess and a second recess, the first recess being formed on the first folded edge and the second recess being formed on the second folded edge. 
     
     
         8 . The heat dissipation base seat as claimed in  claim 1 , wherein the second bent sections have a third folded edge and a fourth folded edge and a third recess and a fourth recess, the third recess being formed on the third folded edge and the fourth recess being formed on the fourth folded edge. 
     
     
         9 . The heat dissipation base seat as claimed in  claim 1 , wherein the third bent sections have a fifth folded edge and a sixth folded edge and a fifth recess and a sixth recess, the fifth recess being formed on the fifth folded edge and the sixth recess being formed on the sixth folded edge. 
     
     
         10 . The heat dissipation base seat as claimed in  claim 1 , wherein the fourth bent sections have a seventh folded edge and an eighth folded edge and a seventh recess and an eighth recess, the seventh recess being formed on the seventh folded edge and the eighth recess being formed on the eighth folded edge.
