Heat exchanger and refrigeration cycle device

Abstract

In a heat exchanger, a first heat exchange unit is formed by curving a third heat exchange unit having a planar shape through L-shape bending, and a second heat exchange unit is formed by curving a fourth heat exchange unit having a planar shape through the L-shape bending, independently of the third heat exchange unit. The first heat exchange unit and the second heat exchange unit are arranged so as to be opposed to each other along a corner portion between adjacent two side surfaces of a casing.
