Cooling apparatus for light valve

Abstract

A cooling apparatus for a light valve of the present invention includes a control box disposed on the back of the light valve to actuate the light valve, followed by a heat pipe and a heat-conducting component pasted upon the inner surface of the control box. The heat-conducting component is connected to a heat-collecting end of the heat pipe and one of its surface contacts with the light valve. The heat of the light valve is conducted to the second part of the control box through the heat-conducting component, and then the heat is conducted to the second part of the control box via the heat pipe pasted upon it. Thus, the heat of the light valve can be removed through the large area of the second part of control box, so as to increase the cooling efficiency and simplify the cooling apparatus.

 a control box, disposed near the light valve, at least one heat pipe being pasted upon the surface of the control box, the heat pipe having a heat-collecting end, and    a heat-conducting component, disposed on the control box and connected to the heat-collecting end of the heat pipe, and one surface of the heat-conducting component being contacted with the light valve.    
   
   
       2 . The cooling apparatus for a light valve according to  claim 1 , wherein the heat pipe and the heat-conducting component are pasted upon the same surface of the control box.  
   
   
       3 . The cooling apparatus for a light valve according to  claim 2 , wherein the surface of the control box is the inner surface of the control box.  
   
   
       4 . The cooling apparatus for a light valve according to  claim 1 , wherein the control box is composed of a first part of the control box and a second part of the control box.  
   
   
       5 . The cooling apparatus for a light valve according to  claim 1 , wherein a heat conduction cushion is disposed between the heat-conducting component and the light valve.  
   
   
       6 . The cooling apparatus for a light valve according to  claim 1 , wherein the heat pipe is fixed on the control box by using a fixing member.  
   
   
       7 . The cooling apparatus for a light valve according to  claim 1 , wherein the heat pipe is fixed on the control box by using heat conduction glue.  
   
   
       8 . The cooling apparatus for a light valve according to  claim 1 , wherein an electrical circuit board is disposed in the control box.  
   
   
       9 . The cooling apparatus for a light valve according to  claim 8 , wherein the heat-conducting component passes through the electrical circuit board and contacts with the back of the light valve.  
   
   
       10 . The cooling apparatus for a light valve according to  claim 8 , wherein the heat-conducting component is composed of a first heat-conducting plate and a second heat-conducting plate, and the second heat-conducting plate fixes the electrical circuit board and the light valve.
