Abstract
A heat exchanger comprising an elongate tank with top, bottom, side, front and rear walls. A plurality of longitudinally spaced partitions are positioned within the tank and define an elongate serpentine or zig-zag liquid conducting flow passage with upstream and downstream ends. An elongate serpentine or zig-zag formed fluid coolant conducting coil is positioned centrally within and extends longitudinally of the flow passage. The coil has an upstream end portion exiting the tank at the downstream end of the flow passage and a downstream end portion exiting the tank at the upstream end of the flow passage. Liquid inlet and outlet fittings connected with a valve-controlled fluid supply and dispensing means conduct liquid into and out of the flow passage. A fluid recirculating pump has a suction side connected with the downstream end of the flow passage and a discharge side connected with the upstream end of the flow passage and continuously recirculates liquid longitudinally within the flow passage and about the coil.
