<p><P>PROBLEM TO BE SOLVED: To provide an evaporator capable of improving cooling performance. <P>SOLUTION: A leeward tube row 11 of this evaporator 1 is provided with first to third tube groups 11A, 11B, 11C, and a windward tube row 12 thereof is provided with fourth and fifth tube groups. Within a third section 17 of a leeward upper header portion 5 with which heat exchange tubes 9 of the third tube group 11C communicate, a resistance member 36 for flow division is provided so as to divide the interior of the third section 17 into a first space 38 which the heat exchange tubes 9 face, and a second space 37 which is separated from the first space 38 and into which refrigerant flows, and a plurality of refrigerant passage holes 39 are formed on the resistance member 36 for flow division. The leeward upper header portion 5 has a flow cutoff member 41 for preventing flow of the refrigerant into the first space 38 of the third section 17. The third section 17 of the leeward upper header portion 5 communicates with a fourth section of the windward upper header portion 6 via refrigerant communication passages. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
