次に、図７及び図８は本発明の第３実施例の熱交換器であり、この例が図６のそれと異なる点は、図６のタンク１１の変わりに、偏平チューブ１の流通方向に、厚みの厚いフランジ１２が接続されたものである。そして、このフランジ１２に図示しないダクトがボルト等により固定されるものである。
そして、第２実施例と同様にケーシング３の開口端がフランジ１２の開口縁にパッキン２１を介して接続され、その接続部がカシメ固定されるものである。 Next, FIGS. 7 and 8 show a heat exchanger according to a third embodiment of the present invention. The difference of this example from that of FIG. 6 lies in that, instead of the tank 11 of FIG. The thick flange 12 is connected. A duct (not shown) is fixed to the flange 12 with bolts or the like.
Then, similarly to the second embodiment, the opening end of the casing 3 is connected to the opening edge of the flange 12 via the packing 21, and the connecting portion is caulked and fixed.
