Abstract
A heat exchanger includes: flat heat transfer tubes having refrigerant flow passages, extending in an up-down direction, spaced apart from each other in a lateral direction and arranged in two rows; and corrugated fins each provided between associated adjacent ones of the flat heat transfer tubes in the two rows, each joined to the associated adjacent flat heat transfer tubes from top to bottom in the up-down direction, and each having a protruding portion that protrudes forward relative to front-side end portions of the associated adjacent flat heat transfer tubes in a front-side one of the two rows. The position of the front-side end portion of each of the flat heat transfer tubes in the front-side row and the length of the protruding portion in the front-rear direction are not unchanged from top to bottom in the up-down direction.
