Abstract

The invention relates to a cooling system for a work vehicle. The cooling system includes a frame and a fan which is mounted in a door which pivotally coupled to the frame. A front engine radiator extends between the left and right sides of the frame. A left side oil cooler extends between the fan and the radiator. A right side hydraulic oil cooler extends between the fan and the radiator. A hydraulic reservoir is spaced apart from the front heat exchanger. A non-fixed fuel cooler is mounted between the radiator and the hydraulic reservoir. The non-fixed fuel cooler is pivotal about a first vertical pivot axis. A non-fixed AC condenser cooler is mounted between the radiator and the hydraulic reservoir. The non-fixed AC condenser cooler is pivotal about a second vertical pivot axis. The hydraulic reservoir has angled walls to accommodate pivoting of the non-fixed coolers.

Claims

exact text as granted — not AI-modified
1 . A cooling system for a work vehicle, comprising:
 front heat exchanger;   a fan spaced apart to the rear of the front heat exchanger, the fan being pivotal about a vertical fan pivot axis;   a left side heat exchanger extending between the fan and the front heat exchanger;   a right side heat exchanger extending between the fan and the front heat exchanger;   a left non-fixed cooler mounted adjacent to a front side of the front heat exchanger, the left non-fixed cooler being pivotal about a first vertical cooler pivot axis; and   a right non-fixed cooler mounted adjacent the front side of the front heat exchanger, the right non-fixed cooler being pivotal about a second vertical cooler pivot axis.   
     
     
         2 . The cooling system of  claim 1 , wherein:
 each non-fixed cooler has a first end which is pivotally coupled to a frame and a second end which is pivotal away from the front heat exchanger.   
     
     
         3 . The cooling system of  claim 1 , wherein:
 the front heat exchanger is spaced apart from a hydraulic reservoir; and   the non-fixed coolers are mounted between the front heat exchanger and the hydraulic reservoir.   
     
     
         4 . The cooling system of  claim 1 , wherein:
 each non-fixed cooler is pivotal about a pivot axis which is located near an inboard side of the non-fixed cooler.   
     
     
         5 . The cooling system of  claim 1 , further comprising:
 a tank mounted adjacent a lateral side of the front heat exchanger.   
     
     
         6 . The cooling system of  claim 1 , wherein:
 the front heat exchanger includes a first tank mounted at a left side thereof, and a second tank mounted at a right side thereof.   
     
     
         7 . The cooling system of  claim 1 , wherein:
 the front heat exchanger is a horizontal liquid flow heat exchanger;   the left side heat exchanger is a vertical liquid flow heat exchanger; and   the right side heat exchanger is a vertical liquid flow heat exchanger.   
     
     
         8 . The cooling system of  claim 1 , wherein:
 a hydraulic reservoir is spaced apart from the front heat exchanger, and the non-fixed cooler is mounted between the front heat exchanger and the hydraulic reservoir.   
     
     
         9 . The cooling system of  claim 3 , wherein:
 the hydraulic reservoir has angled walls to accommodate pivoting of the non-fixed cooler.   
     
     
         10 . The cooling system of  claim 1 , wherein:
 the front heat exchanger includes a pair of fluid tanks on opposite sides thereof.   
     
     
         11 . A cooling system for a work vehicle, comprising:
 front heat exchanger;   a fan spaced apart to the rear of the front heat exchanger, the fan being pivotal about a vertical fan pivot axis;   a left side heat exchanger extending between the fan and the front heat exchanger;   a right side heat exchanger extending between the fan and the front heat exchanger; and   a non-fixed cooler mounted adjacent to a front side of the front heat exchanger, the non-fixed cooler being pivotal about a first vertical cooler pivot axis.   
     
     
         12 . The cooling system of  claim 11 , wherein:
 the non-fixed cooler has a first end which is pivotally coupled to a frame and a second end which is pivotal away from the front heat exchanger.   
     
     
         13 . The cooling system of  claim 11 , wherein:
 the front heat exchanger is spaced apart from a hydraulic reservoir; and   the non-fixed cooler is mounted between the front heat exchanger and the hydraulic reservoir.   
     
     
         14 . The cooling system of  claim 11 , wherein:
 the non-fixed cooler is pivotal about a pivot axis which is located near an inboard side of the non-fixed cooler.   
     
     
         15 . The cooling system of  claim 11 , further comprising:
 a tank mounted adjacent a lateral side of the front heat exchanger.   
     
     
         16 . The cooling system of  claim 11 , further comprising:
 a first tank is mounted adjacent a left side of the front heat exchanger; and   a second tank is mounted adjacent a right side of the front heat exchanger.   
     
     
         17 . The cooling system of  claim 11 , wherein:
 the front heat exchanger is a horizontal liquid flow heat exchanger;   the left side heat exchanger is a vertical liquid flow heat exchanger; and   the right side heat exchanger is a vertical liquid flow heat exchanger.   
     
     
         18 . The cooling system of  claim 13 , wherein:
 the hydraulic reservoir has angled walls to accommodate pivoting of the non-fixed cooler.   
     
     
         19 . A cooling system comprising:
 a frame having a front, a rear, a left side and a right side;   a non-fixed fan coupled to the frame between the left and right sides thereof;   a front horizontal liquid flow engine radiator extending between the left and right sides of the frame;   a left side vertical liquid flow oil cooler extending between the fan and the radiator;   a right side vertical liquid flow hydraulic oil cooler extending between the fan and the radiator;   a hydraulic reservoir spaced apart from the front heat exchanger; and   a non-fixed fuel cooler mounted between the radiator and the hydraulic reservoir, the non-fixed fuel cooler being pivotal about a first vertical pivot axis; and   a non-fixed AC condenser cooler mounted between the radiator and the hydraulic reservoir, the non-fixed AC condenser cooler being pivotal about a second vertical pivot axis, the hydraulic reservoir having the hydraulic reservoir has angled walls to accommodate pivoting of the non-fixed coolers.
