HEAT EXCHANGER AND WATER HEATER

摘要

A fin includes a cut and raised slit and a cut and raised wall portion. The cut and raised slit is formed in a region adjacent to at least one through hole of a plurality of through holes in a first direction and has a tunnel-shaped hole extending in a second direction intersecting the first direction. The cut and raised wall portion is located in the second direction of the cut and raised slit, protrudes toward a main surface of the fin, and extends along the first direction. Thus, a heat exchanger and a water heater capable of sufficiently conducting an amount of heat of a combustion gas to a heat conduction pipe even in a blind spot of a flow of the combustion gas of the heat conduction pipe and suppressing noise can be realized.

主权项

1. A heat exchanger, comprising:
a plurality of fins each having a main surface and a plurality of through holes arranged as aligned along a first direction in said main surface, and arranged as stacked at a distance from one another; and a heat conduction pipe passing through said plurality of through holes in each of said plurality of fins, at least one fin among said plurality of fins including
a cut and raised slit formed in a region adjacent to at least one through hole of said plurality of through holes in said first direction and having a tunnel-shaped hole extending in a second direction intersecting said first direction, anda cut and raised wall portion located in said second direction of said cut and raised slit, protruding toward said main surface of said at least one fin, and extending along said first direction.
