METHOD FOR PRODUCING A HEAT EXCHANGER AND HEAT EXCHANGER OBTAINED BY SAID METHOD, SWAGE AND TUBE EXPANSION DEVICE FOR IMPLEMENTING SAID METHOD |
摘要 |
The invention relates to a method for producing a heat exchanger, in particular for a motor vehicle, a method whereby fluid circulation tubes (3) are inserted into through holes in heat exchange fins (4) and the fluid circulation tubes (3) are subjected to expansion in such a way as to expand a contour (22) of said tubes (3) to ensure contact with said fins (4) at said through holes and, additionally, for at least one of said tubes (3), to deform a concave portion (24) of the contour (22) of said tube or tubes (3), in such a way as to correspondingly deform said through holes. The invention also relates to a device for implementing said method and an exchanger obtained by said method. |
