Heat sink device generating an ionic wind

Abstract

A heat sink device has a metal body connected with a voltage source, multiple sharp teeth formed on one side of the metal body, and a metal grounded member provided separately from the metal body. When the metal body is electrified, the sharp teeth are in a strong electrical field to generate a corona phenomenon, and the air around the sharp teeth is ionized. The ions having the same charge with the sharp teeth will be rejected by the sharp teeth, and all moves to the metal grounded member, whereby an electric wind is generated to dissipate the heat.

1 . A heat sink device comprising:
 a metal body connected with a voltage source to electrify the metal body, and having multiple sharp teeth;   a metal grounded member mounted separately from the metal body and corresponding to the sharp teeth on the metal body to allow an ionic wind to be generated from the sharp teeth to the metal grounded member when the metal body is electrified.   
   
   
       2 . The heat sink device by ionic wind as claimed in  claim 1 , wherein the metal body is a vertical sheet, and the sharp teeth are formed on one side of the sheet. 
   
   
       3 . The heat sink device by ionic wind as claimed in  claim 1 , wherein the metal body is a vertical piece, and multiple sharp teeth are formed on one side of the piece. 
   
   
       4 . The heat sink device by ionic wind as claimed in  claim 1 , wherein the metal grounded member is a vertical piece, and has multiple openings defined therein. 
   
   
       5 . The heat sink device by ionic wind as claimed in  claim 1 , wherein the metal grounded member is a reticular piece. 
   
   
       6 . The heat sink device by ionic wind as claimed in  claim 1 , wherein the metal grounded member comprises multiple cooling fins. 
   
   
       7 . The heat sink device by ionic wind as claimed in  claim 1 , wherein multiple cooling fins are provided separately from the metal grounded member. 
   
   
       8 . The heat sink device by ionic wind as claimed in  claim 1 , wherein an insulated frame is mounted between the metal body and the metal grounded member to keep the metal body and the metal grounded member at an interval. 
   
   
       9 . The heat sink device by ionic wind as claimed in  claim 8 , wherein multiple cooling fins are provided separately from the metal grounded member. 
   
   
       10 . The heat sink device by ionic wind as claimed in  claim 1 , wherein the metal body is a vertical piece, the sharp teeth are formed in one side of the piece, the metal grounded member is a vertical piece, and the metal grounded member has multiple openings defined therein. 
   
   
       11 . The heat sink device by ionic wind as claimed in  claim 1 , wherein the metal body is a vertical piece, the sharp teeth are formed in one side of the piece, and the metal grounded member is a reticular piece.
