Vehicle cooling system

Abstract

A vehicle cooling system includes a fan, a first heat exchanger, an upper heat exchanger and a lower heat exchanger. The first heat exchanger is spaced apart in front of the fan. The upper heat exchanger is positioned between a top portion of the fan and a top portion of the first heat exchanger. The lower heat exchanger is positioned between a bottom portion of the fan and a bottom portion of the first heat exchanger. A structural frame supports the first, top and lower heat exchangers, and the frame forming a fan shroud which surrounds the fan.

We claim: 
     
         1 . A vehicle cooling system, comprising:
 a fan;   a first heat exchanger spaced apart from and in front of the fan;   a second heat exchanger positioned between a top portion of the fan and a top portion of the first heat exchanger; and   a third heat exchanger positioned between a bottom portion of the fan and a bottom portion of the first heat exchanger.   
     
     
         2 . The cooling system of  claim 1 , wherein:
 a fan shroud surrounds the fan; and   the second heat exchanger having a housing which is attached to the fan shroud, the fan shroud forming a structural support for a portion of the top heat exchanger.   
     
     
         3 . The cooling system of  claim 1 , wherein:
 the first heat exchanger comprises a radiator;   the second heat exchanger comprises a charge air cooler; and   the third heat exchanger comprises a hydraulic oil cooler.   
     
     
         4 . The cooling system of  claim 1 , wherein:
 a bracket supports a first cooler fame and a bottom cooler frame.   
     
     
         5 . The cooling system of  claim 4 , wherein:
 left and right support arms extend diagonally upwardly and rearwardly from a front end of the bottom cooler frame to a rear end of the upper cooler frame  36 .   
     
     
         6 . A vehicle cooling system, comprising:
 a fan;   a fan shroud surrounding the fan;   a front heat exchanger spaced apart from and in front of the fan;   an upper heat exchanger positioned between a top portion of the fan and a top portion of the first heat exchanger, the upper heat exchanger having a housing which is attached to the fan shroud, the fan shroud forming a structural support for a portion of the upper heat exchanger; and   a lower heat exchanger positioned between a bottom portion of the fan and a bottom portion of the first heat exchanger.   
     
     
         7 . The cooling system of  claim 1 , wherein:
 the front heat exchanger comprises a radiator;   the upper heat exchanger comprises a charge air cooler; and   the lower heat exchanger comprises a hydraulic oil cooler.   
     
     
         8 . A vehicle cooling system, comprising:
 a fan;   a first heat exchanger spaced apart from the fan;   an upper heat exchanger positioned between a top portion of the fan and a top portion of the first heat exchanger, the upper heat exchanger having a housing which is attached to the fan shroud; and   a lower heat exchanger positioned between a bottom portion of the fan and a bottom portion of the first heat exchanger; and   a structural frame, the frame supporting the first, top and lower heat exchangers, and the frame forming a fan shroud which surrounds the fan.   
     
     
         9 . The cooling system of  claim 8 , wherein:
 the first heat exchanger comprises a radiator;   the upper heat exchanger comprises a charge air cooler; and   the lower heat exchanger comprises a hydraulic oil cooler.
