Abstract
A heat exchanger includes a first header that extends in a horizontal direction, a plurality of first heat-transfer tubes that extend in a vertical direction, that are provided to the first header, and that are spaced from each other in a horizontal direction, a second header provided parallel to the first header, a plurality of second heat-transfer tubes that extend in a vertical direction, that are provided to the second header, and that are spaced from each other in a horizontal direction, and a corrugated fin placed between the plurality of first heat-transfer tubes and between the plurality of second heat-transfer tubes. The corrugated fin has an inter-header region between the first header and the second header, and, in the inter-header region, a first drain slit is formed through which meltwater is drained.
