Patent ID: 7089994

Claim:
Cooling system for a farm machine, comprising a heat exchange assembly ( 1 ) designed to receive a cooling air flow (A) in a direction substantially perpendicular to an end surface thereof, said assembly ( 1 ) comprising at least a first and a second radiator ( 2 , 3 , 4 , 5 ) facing each other so as to be passed through by said air flow (A), wherein hinging means ( 31 – 33 ; 43 , 53 – 55 ) are associate with at least the first radiator ( 3 , 4 , 5 ), designed to enable the angular shift of the first radiator ( 3 , 4 , 5 ) with respect to the second radiator ( 2 , 3 , 4 ), between a respective operating position and a respective non-operating position, wherein the hinging means comprise at least an articulation arm ( 43 ) angularly movable around a respective rotation axis, wherein the arm ( 43 ) has an inner cavity which constitutes a passage duct for a fluid passing within the first radiator ( 4 ), wherein the arm ( 43 ) has a first area coupled in a stationary way with a lateral surface of the first radiator ( 4 ), and a second area coupled turnably with a support structure ( 81 ), said cavity having a first opening ( 44 ) on the first area, which is in fluid communication with the first radiator ( 4 ), and a second opening ( 45 ) on the second area, which is in fluid communication with a respective tube ( 47 ) of said fluid, wherein the hinging means comprise two of said articulation arms ( 43 ), an arm ( 43 ) belonging to an inlet duct of said fluid into the first radiator ( 4 ) and the other arm ( 43 ) belonging to an outlet duct of said fluid from the first exchanger ( 4 ).
