Cooling plate and water cooling device having the same

Abstract

A water cooling device includes a cooling plate and a water cooling module. The cooling plate includes a plate and a wording fluid. The plate includes vacuum enclosed space therein. The wording fluid is accommodated in the enclosed space. The water cooling module is connected to the cooling plate.

What is claimed is: 
     
         1 . A cooling plate, comprising:
 a plate including a vacuum enclosed space; and   a working fluid accommodated in the enclosed space.   
     
     
         2 . The cooling plate according to  claim 1 , wherein an outside surface of the plate which is at back of the enclosed space includes a plurality of first concave-convex structures. 
     
     
         3 . The cooling plate according to  claim 2 , wherein the first concave-convex structure is one or a combination of a convex rib, a groove, or a grid. 
     
     
         4 . The cooling plate according to  claim 1 , wherein an inner surface of the plate facing the enclosed space includes a plurality of second concave-convex structures. 
     
     
         5 . The cooling plate according to  claim 4 , wherein the second concave-convex structure is one or a combination of the convex rib, the groove, the grid. 
     
     
         6 . A water cooling device, comprising:
 a cooling plate, including:
 a plate including a vacuum enclosed space; and 
 a working fluid accommodated in the enclosed space; and 
   a water cooling module connected to the cold plate.   
     
     
         7 . The water cooling device according to  claim 6 , wherein the water cooling module includes:
 a cooling plate connector including a cavity, wherein the cooling plate is in the cavity;   a pump disposed in the cavity;   a beat exhaust pan;   a first connecting pipe;   a second connecting pipe, wherein the second connecting pipe and the first connecting pipe are connected between the cooling plate connector and the heat exhaust part; and   a cooling liquid accommodated in the cavity, the heat exhaust part, the first connecting pipe and the second connecting pipe.   
     
     
         8 . The water cooling device according to  claim 7 , wherein an outside surface of the plate contacting the cooling liquid includes a plurality of first concave-convex structures. 
     
     
         9 . The water cooling device according to  claim 7 , wherein the pump is a constant speed pump or a variable frequency pump. 
     
     
         10 . The water cooling device according to  claim 6 , wherein an inner surface of the plate facing the enclosed space includes a plurality of second concave-convex structures.
