摘要： A heat exchange system for a power machine that has an engine compartment and a heat exchanger compartment is discussed. The heat exchange system includes a fan housing located between the heat exchanger compartment and the engine compartment. A fan assembly that includes an axial fan and a radial fan coupled to a center shaft having a longitudinal axis extending through the center shaft is positioned within the fan housing. The fan assembly is operably coupled to a fan drive mechanism that is configured to cause the fan assembly to rotate about the longitudinal axis in a first direction and a second direction. First and second control signals from a controller cause the drive mechanism to rotate in the first and second directions, respectively.
