ABSTRACT:
A heat exchanger including concentric cylindrical elements having fins formed on adjacent surfaces of the cylinders which form a flow passage for polymer. The fins are separated by a series of spaced left-hand and spaced right-hand helical grooves circumferentially around the adjacent surfaces of the cylinders. The left-hand grooves differ in width from the right-hand grooves to promote mixing and improve heat transfer efficiency.
