Claims

[Scope of utility model registration request]

A plurality of water tubes 1 are arranged in parallel, and flat plate-shaped fins 2 are arranged on the outer surface of these water tubes in the same direction with respect to the heated fluid, parallel to the flow direction A, and in a multi-tiered manner in the tube axis direction. An arrangement structure of water tubes with fins, characterized in that these flat fins are provided with an appropriate number of slits 3 in a direction substantially perpendicular to the flow direction of the applied heating fluid.
