Abstract
A second header pipe forming a second header of a refrigerant condenser and a receiver are joined by brazing. In a portion where the second header pipe and receiver are communicated, four ribs provided at a perimeter of a communication hole of the second header pipe are inserted within a communication hole of the receiver, and thereafter ribs are bent in an outer direction of the hole, and the second header and the receiver are provisionally joined at the communication-hole portion prior to brazing. Additionally, after a projection provided on an upper-side cap of the receiver has been inserted into an insertion hole provided in the second header pipe, an end portion thereof is widened outwardly, and the second header pipe and receiver are provisionally joined prior to brazing. In this way, both ends of the receiver are provisionally joined to the second header pipe prior to brazing, and so the second header and the receiver do not slip during brazing.
