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.
Claims7
A heat exchanger comprising a bundle of tubes and a collecting plate formed with a plurality of holes, each tube having an end portion and the tubes being arranged in a bundle divided into rows of tubes with the respective end portions of the tubes being received in the holes in the collecting plate, wherein each said hole in the collecting plate receives the respective end portions of a plurality of adjacent tubes of the bundle, the heat exchanger further including a compressible sealing gasket interposed between the said holes in the collecting plate and the end portions of the tubes received in the holes.
