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

in order to strengthen the connection between the tubes of a heat exchanger (3) and the collector plate (1), in which they are incurred.we're collecting plate (1) to define poinconnage wires (4), (4a) and to form chamfered of dished ends (5) of the crown is then applied on the dished ends (5).a pad plate (6), the arm at the same time, the pipe (3) and the collector plate (1).
