<P>PROBLEM TO BE SOLVED: To provide a heat exchanger which makes it possible to achieve both improvement in the pressure resistance of the headers and control of the pressure loss of a refrigerant. <P>SOLUTION: This heat exchanger includes a pair of headers, and a plurality of flat tubes (11a-11f). The headers comprise a first member (131), and a flat tube holding member (132) for holding the flat tubes (11a-11f) due to end parts of the flat tubes (11a-11f) being adhered thereto. The first member (131) is formed with a main refrigerant passage (131a) vertically extending to allow a refrigerant to flow therethrough, and linking refrigerant passages (231a-231f) leading from the main refrigerant passage (131a) to an end face in the direction in which the flat tubes (11a-11f) are disposed in order to circulate the refrigerant between the main refrigerant passage (131a) and a plurality of refrigerant passages formed in the flat tubes (11a-11f). Intermediate passages (133a-133f) connecting the linking refrigerant passages (231a-231f) and the plurality of refrigerant passages of the flat tubes (11a-11f) are formed in the headers and/or the flat tubes (11a-11f). <P>COPYRIGHT: (C)2012,JPO&INPIT |
