Abstract

An inner fin is a wave fin having board portions extending in a pipe longitudinal direction and a top portion connecting the board portions located adjacent with each other. The wave fin has a wave-shaped cross-section perpendicularly intersecting a pipe longitudinal direction, and the board portion is bent into a waveform extending in the pipe longitudinal direction when seen from a pipe layering direction. A wave pitch WP [mm], a wave depth WD [mm], and a passage width H [mm] are set to satisfy relationships of 2.2≦WP/WD≦4.28 and 0.5≦WD/H≦1.8.
