Abstract

See full text

A heat transfer tube is made of aluminum and includes a streak-shaped Zn diffusion layer (6, 106) which is spirally formed on a circular outer peripheral surface in a length direction. According to this heat transfer tube, even in a case where rainwater or dew concentration water is intensively accumulated in a portion of the outer peripheral surface in a circumferential direction, it is possible to obtain a sufficient corrosion resistance.
