Abstract
An air intake system for an agricultural implement having a mobile frame, an internal combustion engine carried by the frame, a heat exchanger defining front and rear planar faces, an engine driven fan and a walled structure enclosing the engine, heat exchanger and fan. The walled structure defines a screened air inlet through which environmental air is drawn upon operation of the fan. An air plenum directs environmental air between the air inlet and the front face of the heat exchanger. The heat exchanger is mounted proximate to the fan toward one end of the air plenum. A bypass channel arranged adjacent the heat exchanger directs environmental air around the heat exchanger and exhausts a downstream of the rear face of the heat exchanger. Foreign material, carried in the environmental air, is likewise directed around the heat exchanger whereby preventing relatively rapid plugging of the heat exchanger.
