ABSTRACT:
An orchard heat exchanger comprises an engine-driven shaft having an air propeller on each end. The assembly is enclosed in an open-ended horizontal cylindrical shroud, which has a large converging-diverging air inlet at the top, and is trailer mounted. The orchard heat exchanger has the capability of being elevated to treetop level. In a first embodiment, the engine-propeller-shroud assembly may be rotated in a horizontal plane. In a second embodiment, there is no horizontal rotational capability, but the cylindrical shroud is fitted with directional louvers at each end.
