Strip heatsink

Abstract

A strip heatsink has a base, multiple dissipating strips and a fastening loop. The strip heatsink uses a row of the dissipating strips to replace one conventional fin, and a shape of the strip part of each dissipating strip is circular. Therefore a whole surface area of the row of the dissipating strips is much bigger. Besides, because a cross section area of the mounting part is bigger than a cross section area of the strip part in a dissipating strip, the strip parts of the dissipating strips are mounted separately, and the blocking of the airflow is reduced. Therefore, air can flow more smoothly in an interval between the strip parts. To sum up, the strip heatsink enhances the heat conduction by increasing the whole surface area, and enhances the heat convection by making more space between the dissipating strips.

What is claimed is: 
     
         1 . A strip heatsink comprising:
 a base having a mounting hole formed through the base;   multiple dissipating strips mounted securely in the mounting hole of the base, and each dissipating strip having:
 a strip part having a top end; and 
 a mounting part formed on a bottom of the strip, wherein a cross section area of the mounting part is bigger than a cross section area of the strip part, and the mounting parts of the dissipating strips are flush with each other; and 
   a fastening loop mounted tightly around the mounting parts of the dissipating strips, mounted tightly in the mounting hole of the base, made of resilient material, and having:
 an outer diameter decreased gradually; 
 a top side; and 
 a bottom side. 
   
     
     
         2 . The strip heatsink as claimed in  claim 1 , wherein the top ends of the strip parts of the dissipating strips are bent outward. 
     
     
         3 . The strip heatsink as claimed in  claim 1  further comprising a periphery dissipating assembly and a central dissipating assembly, wherein
 the periphery dissipating assembly comprises some of the dissipating strips; and 
 the central dissipating assembly is surrounded by the periphery dissipating assembly, comprises the rest of the dissipating strips, and each dissipating strip of the central dissipating assembly is shorter than each dissipating strip of the periphery dissipating assembly. 
 
     
     
         4 . The strip heatsink as claimed in  claim 3 , wherein the top ends of the strip parts of the dissipating strips of the periphery dissipating assembly are bent outward. 
     
     
         5 . The strip heatsink as claimed in  claim 1 , wherein
 the mounting parts of the dissipating strips protrude through the base; and   the fastening loop is mounted below the base, and the fastening loop is narrower from the bottom side to the top side.   
     
     
         6 . The strip heatsink as claimed in  claim 4 , wherein
 the mounting parts of the dissipating strips protrude through the base; and   the fastening loop is mounted below the base, and the fastening loop is narrower from the bottom side to the top side.   
     
     
         7 . The strip heatsink as claimed in  claim 1 , wherein the base has multiple connecting holes formed through the base, and arranged surrounding the mounting hole. 
     
     
         8 . The strip heatsink as claimed in  claim 6 , wherein the base has multiple connecting holes formed through the base, and arranged surrounding the mounting hole. 
     
     
         9 . The strip heatsink as claimed in  claim 1 , wherein
 the mounting hole of the base is rectangular;   a cross section of the mounting part of each dissipating strip is rectangular; and   a cross section of an inner space surrounded by the fastening loop is rectangular.   
     
     
         10 . The strip heatsink as claimed in  claim 8 , wherein
 the mounting hole of the base is rectangular;   a cross section of the mounting part of each dissipating strip is rectangular; and   a cross section of an inner space surrounded by the fastening loop is rectangular.   
     
     
         11 . The strip heatsink as claimed in  claim 1 , wherein
 the mounting hole of the base is rectangular;   a cross section of the mounting part of each dissipating strip is hexagonal; and   a cross section of an inner space surrounded by the fastening loop is rectangular.   
     
     
         12 . The strip heatsink as claimed in  claim 8 , wherein
 the mounting hole of the base is rectangular;   a cross section of the mounting part of each dissipating strip is hexagonal; and   a cross section of an inner space surrounded by the fastening loop is rectangular.
