Abstract
A heat exchanger includes a plurality of heat exchange modules. Each of the plurality of heat exchange modules includes a pair of headers, a plurality of flat heat-transfer tubes, and a plurality of corrugated fins. The plurality of corrugated fins each have a corrugated shape and are each placed between ones of the flat heat-transfer tubes that face each other. The corrugated shape has apices joined to the flat heat-transfer tubes. The plurality of corrugated fins each include fin modules between the a pieces. The fin modules are arranged in the up-down direction. One of the corrugated fins situated on a leeward side in the direction of flow of the air is higher in outside-tube heat transfer coefficient than is one of the corrugated fins situated on a windward side in the direction of flow of the air.
