A microchannel heat exchanger includes a two headers and tubes that extend between the headers. Each tube has an elongated cross-section, the cross-section having a first end and an opposing second end. In one example, each tube is angled such that a line defined between the ends of each tube is angled relative to the horizontal. As the tubes are angled, water that collects on the tubes is directed away from the tubes. In another example, a plate fin directs water away from the tubes. The plate fin includes openings, and a louver including parallel vertical slots is located between each of the openings. Each tube is interference fit in one of the openings of the plate fin, positioning a louver between each tube.
