METHOD FOR REINFORCING BY MEANS OF SMALL PLATES AT LEAST END ROWS OF TUBES ENGAGED INTO TUBE PLATES FOR CONSTITUTING A HEAT EXCHANGER, AND SUCH A HEAT EXCHANGER

摘要

For reinforcing the connection between the tubes of a heat exchanger and the tube end plate in which they are engaged, the tube end plate is formed by punching for delimiting collars having a bevelled end and forming bulged bottoms between the collars, then a small plane plate is applied on the bulged bottoms, the small plane plate being brazed in the same time as the tubes and the tube end plate.
