Abstract
A leeward tube row of an evaporator includes first to third tube groups, and a windward tube row thereof includes fourth and fifth tube groups. Within a third section of a leeward upper header portion with which heat exchange tubes of the third tube group communicate, a resistance member for flow division is provided so as to divide the interior of the third section into a first space which the heat exchange tubes face, and a second space which is separated from the first space and into which refrigerant flows. The resistance member for flow division has a plurality of refrigerant passage holes. The leeward upper header portion has a flow cutoff member for preventing flow of refrigerant into the first space of the third section. The third section of the leeward upper header portion communicates with the fourth section of the windward upper header portion via refrigerant communication passages.
