Claims

[Scope of utility model registration request]

A structure of heat transfer fins in a heat exchanger for hot water supply, in which a refrigerant pipe is spirally processed in the height direction, and a height direction heat transfer fin and a substantially horizontal heat transfer fin are attached to the refrigerant pipe. The height direction heat transfer fins are attached to a long strip plate so that its length direction runs along the length direction of the refrigerant pipes, and connect the refrigerant pipes in the width direction of the plate, while allowing heat transfer in a substantially horizontal direction. The fins are attached to a long strip plate so that its length direction is along the length direction of the refrigerant pipe, and the width direction of the plate is arranged on the helical axis side of the spiral, and further along the helical axis side. The band-shaped plate occupied by the refrigerant pipe is cut at approximately regular intervals in a direction perpendicular to the axis of the refrigerant pipe, and divided into narrow protruding pieces, and all or part of the narrow protruding piece is connected to the refrigerant pipe with its tip side A structure of a heat transfer fin in a heat exchanger for hot water supply, characterized in that the heat transfer fin is twisted so that it is non-parallel to the axis of the heat exchanger.
