Abstract
PURPOSE: To produce the captioned pipe of an increased heating surface area by pressure-inserting the forming piece having groove-cutting protrusions on the outside circumference into the heat exchange pipe onto which heat radiation fins have beforehand been inserted, while revolving the forming piece thereby letting the formation of heat radiation assisting spiral grooves and the pressure contacting of the fins be accomplished simultaneously.
CONSTITUTION: A molding die 5 having groove-cutting protrusions 6 on the outside circumference is pushed into the heat exchange pipe 2, onto which heat radiation fins 3 have been inserted, as shown by the solid lines while the forming piece 5 is being revolved by a revolving shaft 4 or is pulled into the pipe 2 as shown by the chain lines. By this pressure insertion, a plurality of spiral grooves 7 are formed on the inside wall surface of the pipe 2 and at the same time the pipe 2 is firmly pressure-contacted to the respective heat radiation fins 3 on the outer side through expansion of the pipe 2.
