摘要: A heat exchanger includes a plurality of refrigerant tubes. In a flow divider, a part of a plurality of capillary tubes is connected to an open end portion on a side of a front tube plate, and a remainder of the plurality of the capillary tubes is connected to an open end portion on a side of a rear tube plate. The plurality of refrigerant tubes include even number refrigerant tubes constituted by an even number of heat transfer tube portions and odd number refrigerant tubes constituted by an odd number of heat transfer tube portions.

摘要: A heat exchanger is provided in which a large number of plate-shaped fins are attached to outer peripheries of heat transfer tubes through which refrigerant flows. Three rows of heat transfer tubes are arranged along an air flow direction. An inlet side heat transfer tube in a case of using as an evaporator or an outlet side heat transfer tube in a case of using as a condenser has the smallest diameter. In a case where the most windward side heat transfer tube has the smallest diameter, a tube diameter of the most windward side heat transfer tube is D1, a tube diameter of the middle heat transfer tube is D2, and a tube diameter of the most leeward side is D3, D1

摘要: A plurality of flat tubes is, at one end thereof, connected to a first header collecting pipe, and is, at the other end thereof, connected to a second header collecting pipe. Some of the flat tubes forms a main heat exchange part, and the other flat tubes forms an auxiliary heat exchange part. The number of flat tubes of the auxiliary heat exchange part is less than the number of flat tubes of the main heat exchange part. The total cross-sectional area of flow paths per flat tube provided in the auxiliary heat exchange part is greater than the total cross-sectional area of flow paths per flat tube provided in the main heat exchange part.
