WIPO Patent Application WO/2018/154806

A1

This heat exchanger has: a plurality of flat heat transfer tubes that have flat cross-sections, that are arranged side by side to face each other on the flat face with a space therebetween, and that are disposed with flow paths in the tubes extending in the vertical direction; and a plurality of corrugated fins that are disposed between facing flat faces folded to zig zag in the vertical direction. A corrugated fin, in which the end of the corrugated fin on the upstream end in the direction of air flow projects further than the end of the flat face, comprises: a drain hole provided in a location corresponding to the center portion of the flat face of the flat heat transfer tube in the direction of air flow; a first louver that has a plurality of slits and a plate that causes air to flow through the slits inclined in the vertical direction in a location further upstream than the drain hole; and a second louver that has a plurality of slits and a plate that causes air to flow through the slits inclined in the vertical direction in a location further downstream than the drain hole.
