HEAT EXCHANGE TUBE, HEAT EXCHANGE UNIT, HEAT EXCHANGE DEVICE, HOT WATER SUPPLY SYSTEM, AND HEAT EXCHANGE TUBE MANUFACTURING METHOD |
| abstract |
An object of the present invention is to increase the degree of contact between a combustion exhaust and a heat exchange pipe, thereby improving the heat exchange efficiency. A heat exchange pipe (2) for exchanging heat of combustion exhaust (EG) to a fluid to be heated (water WR) includes a folded part (4) formed in the middle of the heat exchange pipe (2), and the heat exchange pipe. A pipe line part (6-1) from the start end to the folded part, and a pipe line part (6-2) from the folded part to the end of the heat exchange pipe, and between these pipe parts, A reciprocating pipe section (6) is provided that is arranged with an interval greater than the outer diameter of the pipe section.
