Heat-dissipating fin

Abstract

A heat-dissipating fin includes a sheety main body. The main body is provided with a high-temperature area located at each of two sides thereof, an airflow area located at a midsection thereof for an external airflow to pass through, at least one guide wall formed at the airflow area and having a front end facing the main body, and two inclined guide portions each extending rearward toward one side thereof from a front end thereof. In this way, the external airflow can be guided to the high-temperature areas of the fin to reach greater heat-dissipating efficiency.

1 . A heat-dissipating fin comprising a sheety main body having two high-temperature areas, each of which is located at one of two sides thereof, said main body having an airflow area located at a midsection thereof for airflow to pass through, said main body having at least one guide wall located at said airflow area and having a front end facing a front side of said main body, said at least one guide wall having two inclined guide portions extending bilaterally rearward from the front end thereof. 
   
   
       2 . The heat-dissipating fin as defined in  claim 1 , wherein said main body comprises convexity formed at a center thereof; said guide wall is located in front of said convexity. 
   
   
       3 . The heat-dissipating fin as defined in  claim 2 , wherein said convexity is in the form of water drip. 
   
   
       4 . The heat-dissipating fin as defined in  claim 1 , wherein each of said two inclined guide portions comprises a distal end spaced from one of two lateral edges of said main body. 
   
   
       5 . The heat-dissipating fin as defined in  claim 1 , wherein said at least one guide wall comprises a gap formed at a front end thereof. 
   
   
       6 . The heat-dissipating fin as defined in  claim 1 , wherein said main body comprises at least two of said guide walls arranged in tandem, each of said at least two guide walls having a gap formed at a front end thereof, the gap of said anterior guide wall being larger than that of said posterior guide wall, said main body having a rear through hole running through a rear side thereof and located at the rear most guide wall. 
   
   
       7 . The heat-dissipating fin as defined in  claim 1 , wherein said main body comprises at least two of said guide walls arranged in tandem, each of said at least two guide walls having a gap formed at a front end thereof, the gap of said anterior guide wall being larger than that of said posterior guide wall. 
   
   
       8 . The heat-dissipating fin as defined in  claim 1 , wherein each of said two high-temperature areas comprises at least one through hole provided for a heat pipe to pass through. 
   
   
       9 . The heat-dissipating fin as defined in  claim 8 , wherein said main body comprises a peripheral sidewall extending vertically outward from an external edge of each of said through holes. 
   
   
       10 . The heat-dissipating fin as defined in  claim 1  further comprising a thermally conductive plate, wherein said thermally conductive plate is connected with at least one of the two sides of said main body.
