Abstract

PURPOSE: To improve heat exchange efficiency by forming a linear finned tube having fins at the inside or outside of the tube extrusion and twisting to form a spiral finned tube.
CONSTITUTION: Linear finned tube 1, 3, 5 including a tube 1 that has linear fins 1a only at the inside, a double tube having linear fins 3a between the inner tube 3A and outer tube 3B, or a tube that has linear fins 5a and 5b on the inner and outer faces of the tube in half-and-half direction are worked by extrusion. Next, the linear finned tubes 1, 3, 5 are worked to spiral finned tubes 2, 4 6 respectively by twisting. By this way, apparatus and fixing devices for attaching obstacles in the tube are made unnecessary and corrosion by battery action is also prevented.
