ABSTRACT:
A gas-to-liquid heat exchanger formed by winding circular finned tubing into a helical coil has bare tubing wrapped around the coil such that it nests between adjacent turns of the finned tubing. Fittings at the inlets and outlets of both coils distribute the liquid stream so that a portion flows through each coil. The fan tube coil acts as a cooled baffle which directs the hot gas stream flowing over the finned tubes so that it contacts a greater portion of the finned tube external surface area at high velocity and increases the heat transfer effectiveness. Because the baffle is cooled, its temperature remains close to that of the finned tubing. This protects the baffle and eliminates differential expansion which could cause the baffle to fall off or loosen during operation.
