Heat exchange system

Abstract

A heat exchange system of the invention includes at least multiple grids, a blower including an external rotor motor and a wind blade, a compressor, and a box having multiple exhaust inlets. The exhaust inlets are disposed on the side of the box. The grid is disposed at an exhaust outlet of the box. The blower is disposed in the box and below the grid. The compressor is disposed on bottom surface in the box. The blower is an external rotor axial fan, and the wind blade is disposed outside a rotor of the external rotor motor. The heat exchange system of the invention features simple structure, low cost, large air output, and good blowing effect, and is highly efficient and power-saving.

1 . A heat exchange system, comprising
 multiple grids;   a blower comprising an external rotor motor and a wind blade;   a compressor; and   a box having multiple exhaust inlets;   
       wherein
 said exhaust inlets are disposed on the side of said box; 
 said grid is disposed at an exhaust outlet of said box; 
 said blower is disposed in said box and below said grid; 
 said compressor is disposed on bottom surface in said box; 
 said blower is an external rotor axial fan; and 
 said wind blade is disposed outside a rotor of said external rotor motor. 
 
     
     
         2 . The heat exchange system of  claim 1 , wherein
 said wind blade is disposed outside said rotor of said external rotor motor via a support;   said support comprises an annular cylinder, and multiple mounting feet extending from said annular cylinder;   said wind blade is disposed on said mounting foot; and   said annular cylinder is fit on said rotor of said external rotor motor.   
     
     
         3 . The heat exchange system of  claim 2 , wherein said wind blade is an equal-width blade and in the vicinity of said exhaust outlet of said box. 
     
     
         4 . The heat exchange system of  claim 2 , wherein said annular cylinder is an integral formed cylinder, or a cylinder formed via an annular body with an opening. 
     
     
         5 . The heat exchange system of  claim 2 , wherein inner wall of said annular cylinder is interference fit with outer wall of said rotor. 
     
     
         6 . The heat exchange system of  claim 2 , wherein
 a screw hole is disposed on said mounting foot; and   said wind blade is disposed on said mounting foot via a bolt and a nut.   
     
     
         7 . The heat exchange system of  claim 2 , wherein
 a through hole is disposed on said mounting foot; and   said wind blade is connected to said mounting foot via a rivet.   
     
     
         8 . The heat exchange system of  claim 2 , wherein said wind blade is directly welded on said mounting foot, or directly welded on the outside of said rotor of said external rotor motor. 
     
     
         9 . The heat exchange system of  claim 2 , wherein said wind blade is disposed on said mounting foot via buckling. 
     
     
         10 . The heat exchange system of  claim 2 , wherein said annular cylinder and said mounting foot are integrally formed, or connected to each other as two independent parts via welding, buckling, or riveting.
