Cooling Circuit With Parallel Radiators

Abstract

A cooling circuit comprises an engine and a parallel arrangement. The parallel arrangement comprises a first radiator to cool liquid engine coolant and a second radiator to cool liquid engine coolant. The first and second radiators are flow-parallel to one another.

1 . A cooling circuit, comprising:
 a pump,   an engine,   a thermostat, and   a parallel arrangement, wherein the pump, the engine, the thermostat, and the parallel arrangement are positioned in flow-series with one another, the parallel arrangement comprises a first radiator to cool liquid engine coolant and a second radiator to cool liquid engine coolant, and the first and second radiators are flow-parallel to one another.   
     
     
         2 . The cooling circuit of  claim 1 , wherein the parallel arrangement comprises a first node, a second node, a first flow path from the first node to the second node, a second flow path from the first node to the second node, the first radiator is included in the first flow path, the second radiator is included in the second flow path, and the first and second flow paths are flow-parallel to one another between the first and second nodes and equal in flow resistance. 
     
     
         3 . The cooling circuit of  claim 2 , wherein the first and second flow paths are equal in length. 
     
     
         4 . The cooling circuit of  claim 3 , wherein the first flow path comprises a first plumbing inlet section having a first length from the first node to a first inlet of the first radiator and a first plumbing outlet section having a second length unequal to the first length from a first outlet of the first radiator to the second node, and the second flow path comprises a second plumbing inlet section having the second length from the first node to a second inlet of the second radiator and a second plumbing outlet section having the first length from a second outlet of the second radiator to the second node. 
     
     
         5 . The cooling circuit of  claim 1 , wherein the first and second radiators are identical to one another. 
     
     
         6 . A work vehicle comprising the cooling circuit of  claim 1 . 
     
     
         7 . The work vehicle of  claim 6 , wherein the first radiator and the second radiator are positioned respectively along opposite sides of the work vehicle.
