Cooling system

Abstract

A cooling system is provided. The cooling system includes a first heat exchanger and a second heat exchanger. The first heat exchanger has a first chamber and a second chamber. A plurality of tubes is provided in the first heat exchanger such that the tubes are in fluid communication with the first chamber and the second chamber. The tubes are arranged in a plurality of rows. A baffle is located in the second chamber. The baffle divides the second chamber into a first region and a second region. The first region of the second chamber is in fluid communication with at least one row of tubes. Further, an outlet is provided in fluid communication with the first region. The second heat exchanger includes an inlet in communication with the outlet of the first region.

         7 . The cooling system of  claim 1 , wherein the second heat exchanger is a shell and tube type heat exchanger. 
     
     
         8 . The cooling system of  claim 1 , wherein the baffle is a plate. 
     
     
         9 . A method for cooling a working fluid in a hydraulic system comprising:
 receiving a coolant in a first chamber of a first heat exchanger;   introducing the coolant into a plurality of tubes, the tubes being arranged in a plurality of rows;   directing the coolant through the plurality of tubes towards a second chamber of the first heat exchanger;   providing a baffle in the second chamber, the baffle configured to define a first region and a second region within the second chamber, wherein the first region is in fluid communication with at least one row of tubes from the plurality of tubes; and   introducing the coolant from the first region to a second heat exchanger configured to remove heat from the working fluid.   
     
     
         10 . The method of  claim 9  further comprising receiving the coolant in the first chamber through a power source. 
     
     
         11 . The method of  claim 9  further comprising placing the at least one row of tubes, in fluid communication with the first region, in a direction of flow of a cooling medium. 
     
     
         12 . The method of  claim 9  further comprising directing the coolant from the second heat exchanger to a second region of the first chamber. 
     
     
         13 . A machine comprising:
 a power source;   a first heat exchanger comprising:
 a plurality of tubes in fluid communication with a first chamber and a second chamber, the tubes being arranged in a plurality of rows;
