Abstract
A square shaped upper side level difference and a squarely annular lower side level difference part are provided on a reverse arc shaped recess part formed in the modulator, and a second through hole is provided so as to bore through the lower side level difference part. By this arrangement, in brazing the modulator to an arc shaped projection part formed on the right side header, heated and melted brazing material can intensively flow into the surface contacting part between the surface of the upper side level difference part and the surface of the projection part and between the surface of the lower side level difference part and the surface of the projection part. As a result, the right side header and the modulator can exactly be brazed and therefore there is no possibility of the occurrence of defective brazing around the second through hole.
