Abstract
A heat exchanger with a simple configuration and having a high strength is disclosed. The heat exchanger is configured by sandwiching both sides of a core created by layering tubes and corrugated fins by a pair of side plates and brazing the connecting bar on the ends of each tube and side plate with the bar inserted into header. The header and side plate are coupled with a approximately U-shape coupling member in addition to the connecting bar 13. This coupling member is configured of an arc section that covers the header and an arm section that has a locking section to lock onto a -shaped bend section of side plate. The arc section is fixed onto header with brazing, and arm section is fixed to side plate. The vibration conveyed from the bracket to the side plate is conveyed to the header via the connecting bar and coupling member, and the strength of the coupling sections of the header and side plate is much higher than the strength found in conventional structures.
