Abstract
A heat exchanger includes: a heat exchange body having flat tubes arranged and spaced from each other in a horizontal direction; an upper header provided at an upper end of the heat exchange body; a lower header provided at a lower end of the heat exchange body; and a partition plate provided in at least one of the upper and lower headers to partition the heat exchange body into a plurality of regions in a horizontal direction. The partition plate is provided such that in each of the regions, refrigerant flows in the opposite direction to the flow direction of the refrigerant in an adjacent one of the region. The partition plate is also provided such that regarding the regions, the more downward the region relative to the flow of the refrigerant when the heat exchanger operates as a condenser, the smaller the region's flow passage cross-sectional area.
