PURPOSE:To make the arranging density of many fine heat transfer tubes made of resin uniform, to realize a zigzaglike fluid passage structure and to improve heat exchanging efficiency by coating the many heat transfer tubes with adhesive, winding them on a core rod of a predetermined structure as a rolled heat transfer tube, and engaging it with a baffle plate. CONSTITUTION:Heat transfer tubes 11 each made of many synthetic resin fine tubes are aligned in parallel at an equal interval. They are coated at a predetermined interval in a stripe shape with adhesive 12. The discs of core rods 5 are abutted against the corresponding adhesive coating parts from the coated end side, and adhesively wound on the outer surface while adhesively rotating. Thus, a ringlike adhesive layer 6 sealed from the inner surface side to the outer surface side is formed at the adhered part on the outer surface of the disc 4, bundled, and an inner partition chamber 13 is formed. The discs 4 are disposed on non-corresponding predetermined adhesive layer 6 to be engaged with a ringlike baffle plate 7 to form an outer partition wall 12. Eventually, a predetermined ending process is performed on the respective heat transfer tubes 11. The rolled heat transfer tube body 10 is contained and installed in a tube body 1 through the baffle plate 7. |
