Claim Text:
1. A heat exchanger, in which a plurality of plate-shaped fins are attached to outer peripheries of heat transfer tubes through which a refrigerant flows, the heat exchanger exchanging heat between the refrigerant and the air, the heat exchanger comprising: first, second, and third rows of heat transfer tubes arranged along a direction of an air flow, the air flow being generated by a fan, the second row being disposed between the first and third rows along the direction of the air flow; and first plate-shaped fins attached to the outer periphery of the heat transfer tube in the first row, second plate-shaped fins attached to the outer periphery of the heat transfer tube in the second row, and third plate-shaped fins attached to the outer periphery of the heat transfer tube in the third row, wherein: among the first, second, and third rows of the heat transfer tubes: the heat exchanger is configured for use as an evaporator such that: the refrigerant flowing through the heat exchanger contains a highest percentage of liquid refrigerant flows through the heat transfer tube in the first row; and a width of the first plate-shaped fins is larger than widths of the second plate-shaped fins and the third plate-shaped fins.
