To simplify the piping construction around a heat exchanger of an air conditioner and reduce the power consumption by a method wherein a refrigerant distributor to distribute refrigerant in between two flat plate, a distribution pipe to lead the refrigerant from the refrigerant distributor to a heat exchanger, a part of a bend pipe of the heat exchanger and a header are integrally formed into one piece.
An end plate 4 of a heat exchanger is composed of two plates, and grooves to form distribution pipes 2-1, 2-2, 2-3 and 2-4, grooves to compose bend pipes 5-1, 5-2, 5-3, and 5-4, and an inlet of a refrigerant distributor 1 are formed on one side. Grooves to compose the refrigerant distributor 1, an opening for the end of a heat transfer tube and a groove to compose a header 7 are formed on the other side. The two plates are connected by such a mean as brazing with a brazing filler metal in a furnace, and cooling paths 1, 2-1, 2-2, 2-3 and 2-4 are form by the two plates.
