Temperature-difference radiating apparatus

Abstract

A temperature-difference radiating apparatus comprises a radiating fan, a valving cylinder, a power cylinder and a vessel. The radiating fan and the valving cylinder are connected to both sides of the radiating fan through a first link and a second link, respectively. The air in the valving cylinder is communicated with air in the power cylinder through the vessel. A CPU to be cooled can be placed below the valving cylinder and the heat generated by the CPU can expand the air in the valving cylinder and the power cylinder to repeatedly drive the first link and the second link. Therefore, the radiating fan is rotated by the first link and the second link to remove the heat generated by the CPU.

I claim:  
     
         1 . A temperature-difference radiating apparatus comprising: 
 a radiating fan;    a valving cylinder having a valving piston therein, the valving piston having a first link on one side thereof and connected to one end of the radiating fan;    a power cylinder having a power piston therein, the power piston having a second link on one side thereof and connected to another end of the radiating fan;    a vessel through which air in the valving cylinder is communicated with air in the power cylinder.    
     
     
         2 . The temperature-difference radiating apparatus as in  claim 1 , wherein the radiating fan is a blast fan or an axial fan.  
     
     
         3 . The temperature-difference radiating apparatus as in  claim 1 , wherein the first link has a first pivotal hole connected to a first projecting shaft on one side of the radiating fan.  
     
     
         4 . The temperature-difference radiating apparatus as in  claim 1 , wherein the first link has a second pivotal hole connected to a second projecting shaft on another side of the radiating fan.  
     
     
         5 . The temperature-difference radiating apparatus as in  claim 1 , wherein the valving cylinder has a radiating member on an outer wall thereof.  
     
     
         6 . The temperature-difference radiating apparatus as in  claim 1 , wherein the power cylinder has a radiating member on an outer wall thereof.  
     
     
         7 . The temperature-difference radiating apparatus as in  claim 1 , wherein the first link is a crank link.  
     
     
         8 . The temperature-difference radiating apparatus as in  claim 1 , wherein the second link is a crank link.  
     
     
         9 . The temperature-difference radiating apparatus as in  claim 1 , wherein the first projecting shaft has a predetermined angle offset to the second projecting shaft with reference to the a rotation axis of the radiating fan.  
     
     
         10 . The temperature-difference radiating apparatus as in  claim 1 , wherein the predetermined angle offset is 90 degree.
