Abstract
A heat exchanger comprises a bundle of parallel tubes disposed in rows and having respective end portions each of which is received in a collecting plate which is formed with holes. These holes may be bounded by lips. Each hole in the collecting plate receives the respective end portions of a plurality of adjacent tubes forming part of different ranges of the tube bundle. The pitch defined between two tubes in two adjacent rows may thus be reduced to a minimal value so as to optimize the performance of the heat exchanger, with a minimal width of the collecting plate.
