Abstract
A heat exchanger includes: a water-repellent coating film on part of a surface of the heat exchanger. The surface on which the water-repellent coating film is disposed includes a surface structure including protrusions. D/L<0.36, D/L>0.4×(L/H), D<200, L−D<1000, H>700, 0>1.28×D×10−2+2.77 ×(L−D)×10−3−1.1×D2×10−5−5.3×(L−D)2×10−7−9.8×D×(L−D)×10−6−2.0, and 90°<θ<120°, where L is an average pitch of the protrusions in nm, D is an average diameter of the protrusions in nm, H is an average height of the protrusions in nm, and θ is a contact angle of water on a smooth plane of the water-repellent coating film.
