Cooling Fin

Abstract

A cooling fin is integrally formed and comprises a board body, a passage penetrating the board body, and plural heat dissipating portions located outside the board body in the direction along the passage. Between each two neighboring portions is defined a heat dissipating space. By such arrangements, the cooling fin has the advantages such as better heat dissipation effect, easy to assemble and simple structure without any assembling operations and procedures.

1 . A cooling fin being integrally formed and comprising a board body, and a passage defined in the board body; wherein the board body is provided with an assembling segment at each of two opposite ends thereof in a direction along the passage, and plural heat dissipating portions outside thereof, between each two neighboring portions is defined a heat dissipating space. 
   
   
       2 . The cooling fin as claimed in  claim 1 , wherein the plural heat dissipating portions outside the board body are formed in the direction along the passage. 
   
   
       3 . The cooling fin as claimed in  claim 1 , wherein the cooling fin is integrally formed by aluminum extruding. 
   
   
       4 . The cooling fin as claimed in  claim 1 , wherein the passage is provided with at least one division plate. 
   
   
       5 . The cooling fin as claimed in  claim 1 , wherein the respective heat dissipating portions are defined with plural notches in a vertical direction thereof. 
   
   
       6 . The cooling fin as claimed in  claim 1 , wherein plural cooling fins are used and cooperate with a liquid base assembly, the liquid base assembly is provided with plural spaced inner assembling holes, an inlet and an outlet, the inlet and the outlet are in communication with the respective assembling hole, both ends of the respective cooling fins are disposed between two corresponding assembling holes of the liquid base assembly to make the passage communicate with the inlet and the outlet, so that all the assembling holes are connected in a circulation manner by the respective cooling fins.
