ABSTRACT:
In order to achieve an improvement in productivity and a reduction in production costs, tubes are formed using brazing sheet while eliminating the problems normally associated with forming tubes from a brazing sheet. In each of the tube elements formed from a brazing sheet, at least one ridge projects out from a surface that is in contact with a fin toward the other surface that is in contact with a fin at the opposite side is formed, thereby achieving an improvement in the pressure withstand performance of the tube elements and in the heat exchanging rate. In addition, flat portions where no ridges are formed are provided at the two ends of each tube element to facilitate the work of mounting the tube elements. Moreover, the distance between the header pipes and the ridge end portions is set within a range of 2 mm to 10 mm, in order to ensure good balance between the pressure withstand performance and effective brazing.
