Abstract:
1. A heat exchanger for a refrigerant cycle, comprising: a plurality of tubes in which refrigerant flows in a tube longitudinal direction; a first header tank extending in a direction perpendicular to the tube longitudinal direction to communicate with the tubes at one end side of each tube in the tube longitudinal direction; a second header tank extending in a direction perpendicular to the longitudinal direction of the tubes to communicate with the tubes at the other end side of each tube in the tube longitudinal direction; and a throttle portion for decompressing refrigerant, the throttle portion being provided at a predetermined position of one of the first and second header tanks, wherein: the tubes have outlet openings from which the refrigerant flows out, opened into the one of the first and second header tanks; the throttle portion is located between adjacent outlet openings of the tubes; and the tubes include a first group of tubes having the outlet openings located upstream from the throttle portion and a second group of tubes having the outlet openings located downstream from the throttle portion, the throttle portion has an outlet provided by a hole portion formed on the one of the header tanks at a side opposite to the outlet openings of the second group of tubes.
