ABSTRACT:
An elongated heat exchange tube and method of making same are disclosed wherein a pair of elongated generally right-angle metallic wall members are adapted for mirror image connection to form an outer tube wall of generally rectangular transverse cross-section. A plurality of internal generally planar heat transfer fins having 90.degree. weld flanges are secured to inner surfaces of the right-angle walls and define longitudinal flow passages through which heated combustion gases are passed to effect improved heat transfer to the outer peripheral wall of the heat transfer tube with enhanced heat convection to a medium in contact with the outer surface of the outer tube wall. A plurality of the heat exchange tubes may be mounted within a compact steam generator for highly efficient production of steam for a steam oven.
