Abstract (en)
[origin: EP0845647A1] The heat exchanger includes flat tubes (1) which have one end sector (1a) deformed to fit in a component (3) forming a connection cavity. This end sector is twisted and/or bent to form an adjacent section (1b) of smaller measurement across the cross section. The flat tubes may be twisted about an angle ( alpha , beta ) between about 10 and 20 degrees at the end fitting in the connection component. This end may be bent in a V shape or a U shape so that the flanks of the bent end sectors are in contact with each other.
