Claims

[Scope of utility model registration request]

A gas introduction pipe into which combustion gas is introduced, an inner cylindrical case that houses this gas introduction pipe, an outer cylindrical case that houses this inner cylindrical case, an outer peripheral surface of the gas introduction pipe, and an inner periphery of the inner cylindrical case. A combustion gas flow path formed between surfaces, and a liquid flow path formed between an outer circumferential surface of the cylindrical inner case and an inner circumferential surface of the cylindrical outer case, the combustion gas in the combustion gas flow path being an outlet for discharging fluid from the liquid flow path is provided in the inner cylindrical case; an inlet for allowing liquid to flow into the liquid flow path is provided at one end of the outer cylindrical case; and an outlet for flowing fluid out from the liquid flow path. is provided at the other end of the cylindrical outer case, and a spiral guide fin is provided on the outer peripheral surface of the cylindrical inner case, and the liquid flowing from the inlet is directed to the starting end of the guide fin. A heat exchanger characterized in that a guide mechanism for guiding the gas is provided, and a bubble guide groove along the central axis of the gas introduction pipe is provided in the upper inner circumferential wall of the cylindrical outer case.
