ABSTRACT:
A heat exchanger for various kinds of liquid and gaseous fluids includes a tubular conduit having a corrugated heat exchanging outer wall and a series of shaft-mounted turbulator units mounted for rotation within the conduit on the axis thereof. Each of the turbulators diverts a portion of the flow through the tubular conduit and directs it radially outwardly into contact with the heat exchanging wall of the conduit. In a preferred embodiment, the turbulator provides a recirculation of a portion of the fluid flow by directing it in an upstream direction within the turbulator for radial discharge from the upstream end thereof and return downstream flow. The heat exchanger may be used in place of conventional automotive heat exchanging radiator constructions and may utilize welded or unitary constructions that eliminate troublesome soldered construction typical of the prior art. The enhanced heat exchaning capability provided by the present invention allows a substantial reduction in the space required for the heat exchanger, thereby allowing the space to be utilized for other similar heat exchanging apparatus for the same or another fluid.
