HEAT EXCHANGER, AND REFRIGERATING CYCLE DEVICE EQUIPPED WITH HEAT EXCHANGER

摘要

A heat exchanger includes a plurality of heat exchange units 10, 20 each including a plurality of fins 11, 21 arranged at intervals such that air passes between adjacent fins and a plurality of heat transfer tubes 12, 22 through which a refrigerant flows. The heat transfer tubes extend through the fins 11, 21 in a direction of arrangement of the fins. The heat transfer tubes are arranged at multiple levels in a level direction perpendicular to an air passing direction. The heat exchange units are arranged in multiple rows in a row direction, serving as the air passing direction. The heat exchanger further includes a row straddling header 40. Refrigerant passages are provided such that the refrigerant flowing from inlets of the refrigerant passages turns in the row straddling header 40 to outlets of the refrigerant passages. The row straddling header 40 has an interior separated into a plurality of chambers arranged in the level direction. The refrigerant passage is isolated for its corresponding chamber.
