Abstract:
An agricultural harvester () has a chassis () supported on a plurality of wheels () for travel over the ground; a harvesting implement () supported on the front of the chassis (); an internal combustion engine () disposed on the chassis () behind the harvesting implement (); a radiator () coupled to the internal combustion engine () to transfer heat from engine coolant to ambient air; a fan () disposed to draw a flow of cooling air through the radiator having a first flow rate; and a conduit () configured to conduct substantially the entire first flow rate of air to the radiator (). The conduit defines a lower air-impermeable enclosure surrounding the inlet of the radiator fixed to an upper enclosure comprising a plurality of screen walls for passing substantially the entire flow of cooling air therethrough.

Abstract:
A two-stage venturi cooler comprises a first tubular conduit having a longitudinal axis, the first elongate tubular conduit having an exhaust gas inlet at one end, a mixed gas outlet at an opposing end, and a cooling gas inlet, wherein structures inside the first stage define a venturi that forms a column of mixed gas, wherein the column of mixed gas comprises a ring of exhaust gas surrounding a core of cooling gas; and a second tubular conduit that is coaxial with the first tubular conduit, wherein the second tubular conduit has a mixed gas inlet at one end and a mixed gas outlet at an opposing end, and wherein the mixed gas inlet is to receive the column of mixed gas and to surround the column of mixed gas with an entrained column of ambient air.
