A heat exchange apparatus has a housing, a first fan cooperative with the housing for drawing air through the housing, an air flow line extending within the housing, a second fan connected to the air flow line for drawing air along the air flow line, and a coolant tube extending in a helical pattern around in the air flow line. A conduit extends over and around the coolant tube and the air flow line. The second fan passes air in heat exchange relationship to the coolant tube interior of the conduit. The housing can be placed forwardly of an engine of a vehicle.
