Abstract

PURPOSE: To improve the boiling or condensing heat transferring property of the fluid in a pipe by a method wherein narrow spiral openings inside the pipe are formed on the wall of a pipe having grooves on the inner surface.
CONSTITUTION: When a mandrel is inserted into the internal part of a metal pipe provided with many fine grooves inside and the pipe is pressed as twisting moment is given to both ends of the pipe, the pipe makes such a shape that cylindrical parts and fold parts 4 stretch spirally by turns. A spirally continued tunnel 5 is formed on the inside of the fold part 4. Space parts 6 are connected with narrow openings 7 having irregular intervals through grooves 21.
