Radiation fin structure

Abstract

A radiation fin structure aims to disperse heat for personal or notebook computers and peripheral devices thereof. The structure includes a base deck at the bottom end of the radiation fins with grid type passages formed therein to form a closed loop. The closed loop is filled with a liquid or gas heat dissipation medium to the amount about 50% to 90% of the internal volume capacity of the grid type passages. When the base deck is in contact with the contact surface of a computer heat generating element, heat concentrates on the heat absorption end of the base deck and is transferred to the fin-type heat dissipation section to be dispelled by a fan to improve heat dissipation effect.

1 . A radiation fin structure, comprising: 
 a base deck having gird type passages formed therein consisting of longitudinal and transverse passages on neighboring sides communicating with one another to form a closed loop which is filled with a heat dissipation medium; and    a fin-type heat dissipation section located above the base deck.    
   
   
       2 . The radiation fin structure of  claim 1 , wherein the heat dissipation medium is liquid or gas.  
   
   
       3 . The radiation fin structure of  claim 1 , wherein the heat dissipation medium is filled to the amount about 50% to 90% of the internal volume capacity of the gird type passages.  
   
   
       4 . The radiation fin structure of  claim 1 , wherein the closed loop has reciprocal passages.  
   
   
       5 . The radiation fin structure of  claim 1 , wherein the base deck has an outlet connection end on one side and an inlet connection end on another side thereof to form an open loop circulation system.  
   
   
       6 . The radiation fin structure of  claim 5 , wherein the open loop is connected to an external heat exchange circulation system.  
   
   
       7 . The radiation fin structure of  claim 1 , wherein the radiation fins are located in a heat generation space on the base deck of a same height and have different heights and are arranged in different densities.
