HEAT EXCHANGER AND REFRIGERATION CYCLE AIR CONDITIONER USING SAME

摘要

Provided is a heat exchanger (1), including: a parallel-flow-type heat exchange unit (3) including a plurality of heat exchange pipes (11, 13) each extending in an up-and-down direction, the parallel-flow-type heat exchange unit including at least a front row portion (7) and a back row portion (9), the front row portion and the back row portion each including the plurality of heat exchange pipes each extending in the up-and-down direction; and a plate fin-and-tube-type heat exchange unit (5) including a plurality of plate fins (25) each extending in the up-and-down direction, the plate fin-and-tube-type heat exchange unit being arranged in front of a lower portion of a front surface of the parallel-flow-type heat exchange unit. An outlet end of the plate fin-and-tube-type heat exchange unit and an inlet end of the parallel-flow-type heat exchange unit are connected to each other by a pipe.
