Abstract
A heat exchanger comprises a bundle of parallel tubes disposed in ranges 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 pair of adjacent tubes forming part of different ranges of the tube bundle. These ranges are arranged back-to-back, but leaving at each side of the interface between the tubes a small free space within the hole of the collecting plate. A pair of opposed beak-like projections are formed on the edge of each hole so as to fill this free space. The pitch defined between two tubes in two adjacent ranges is reduced to a minimal value so as to optimize the performance of the heat exchanger, with a minimal width of the collecting plate.
