Cooling device for cooling light guide plate

Abstract

A cooling device for cooling a plurality of light guide plates includes a plurality of positioning members stacked together, a support frame supporting the plurality of positioning members, and a cooling fan positioned in the support frame. Each positioning member includes a bottom plate and a side frame extending from an edge of the bottom plate. The bottom plate and the side frame cooperatively define a receiving groove for receiving the light guide plate. A plurality of support portions are formed on the bottom plate for supporting the light guide plate, and the bottom plate defines a plurality of penetrating holes around the support portions. The cooling device cools all the light guide plates evenly and quickly.

What is claimed is: 
     
         1 . A cooling device for cooling a plurality of light guide plates, comprising:

         2 . The cooling device of  claim 1 , wherein the plurality of penetrating holes are arranged in a matrix. 
     
     
         3 . The cooling device of  claim 1 , wherein a depth of the receiving groove is larger than a total height of the at least one support portion and the plurality of light guide plates are supported on the at least one support portion. 
     
     
         4 . The cooling device of  claim 1 , wherein the support frame comprises two support arms, and each of the two support arms has a top surface; the top surface defines a positioning groove, and the plurality of positioning members are received in the positioning groove of each of the two support arms. 
     
     
         5 . The cooling device of  claim 4 , wherein the cooling fan are positioned between the two support arms. 
     
     
         6 . The cooling device of  claim 1 , wherein each of the plurality of positioning members forms two restricting protrusions on a top surface, and defines two restricting grooves in a bottom surface opposite to the top surface. 
     
     
         7 . The cooling device of  claim 1 , wherein each of the plurality of positioning members forms four support portions parallel to each other, the four support portions are configured to support the plurality of light guide plates, and each pair of the four support portions are configured to support one of the plurality of light guide plates. 
     
     
         8 . The cooling device of  claim 7 , wherein an area of the bottom plate is larger than a sum area of two of the plurality of light guide plates. 
     
     
         9 . A cooling device for cooling a plurality of light guide plates, comprising:
 a plurality of positioning members stacked together;   a support frame supporting the plurality of positioning members; and   a cooling fan positioned in the support frame;   wherein each of the plurality of positioning members defines a receiving groove; at least one support portion is formed in the receiving groove for supporting the plurality of light guide plates, and each of the plurality of positioning members defines a plurality of penetrating holes for air flowing through the plurality of positioning members.   
     
     
         10 . The cooling device of  claim 9 , wherein the plurality of penetrating holes are arranged in a matrix. 
     
     
         11 . The cooling device of  claim 9 , wherein a depth of the receiving groove is larger than a total height of the at least one support portion and the plurality of light guide plates are supported on the at least one support portion. 
     
     
         12 . The cooling device of  claim 9 , wherein the support frame comprises two support arms, and each of the two support arms has a top surface; the top surface defines a positioning groove, and the plurality of positioning members are received in the positioning groove of each of the two support arms. 
     
     
         13 . The cooling device of  claim 12 , wherein the cooling fan are positioned between the support arms. 
     
     
         14 . The cooling device of  claim 9 , wherein each of the plurality of positioning members forms two restricting protrusions on a top surface, and defines two restricting grooves in a bottom surface opposite to the top surface. 
     
     
         15 . The cooling device of  claim 9 , wherein each of the plurality of positioning members forms four support portions parallel to each other, the four support portions are configured to support the plurality of light guide plates, and each pair of the four support portions are configured to support one of the plurality of light guide plates.
