HEAT EXCHANGER AND HOT WATER DEVICE

PROBLEM TO BE SOLVED: To prevent scale from accumulating on an inner wall of a heat transfer pipe, in a heat exchanger including a turbulent flow generation member provided inside the heat transfer pipe.SOLUTION: A heat exchanger includes: a case in which a heating gas is introduced inside; a heat transfer pipe which includes a case internal portion located inside of the case and a case external portion located outside of the case, and in which hot water is circulated inside; and a turbulent flow generation member provided inside the heat transfer pipe, and for generating the turbulence in the flow of the hot water. The turbulent flow generation member is held so as not to come into contact with an inner peripheral surface of the heat transfer pipe in the case internal portion.SELECTED DRAWING: Figure 4 【課題】伝熱管の内部に設けられた乱流発生部材を備える熱交換器において、伝熱管の内壁に缶石が堆積することを防止すること。【解決手段】本発明の熱交換器は、内部に加熱用気体が導入されるケースと、ケースの内部に位置するケース内部分と、ケースの外部に位置するケース外部分とを含み、内部に湯水が流通される伝熱管と、伝熱管の内部に設けられ、湯水の流れに乱れを発生させるための乱流発生部材と、を備える。乱流発生部材は、ケース内部分において伝熱管の内周面と接触しないように保持されている。【選択図】図４
