  • the tubes are preferably provided with winglets, which can significantly increase the turbulence of the first and / or second material flow.
  • winglets can significantly increase the turbulence of the first and / or second material flow.
  • a comparable maximization of the contact surface can be achieved by means of ribs shaped analogously in the metal sheet, for example cooling fins, which at the same time increase the mechanical strength of the heat exchanger at the price of a slight increase in weight and reduce the sound radiation of a corresponding exhaust gas cooler by suppressing surface vibrations.
  • the tubes may be materially connected to the bottom of the housing, so that the resulting atomic or molecular forces support the structural cohesion of the heat exchanger.

Abstract

L'invention concerne un échangeur de chaleur (1) pourvu d'un logement (3) étanche au fluide permettant de conduire un premier flux de matières (4), d'au moins un tube (5 - 10) laissant passer la chaleur, s'étendant dans le logement (3), et permettant de guider un deuxième flux de matières (11), le logement (3) et les surfaces extérieures (12, 13, 14, 15) du ou des tubes (5 - 10) formant des trajets d'écoulement (24) parallèles pour le premier flux de matières (4), lesquels sont délimités frontalement par un fond (21), d'un raccordement (22) par l'intermédiaire duquel le premier flux de matières (4) peut être introduit dans la zone du fond (21) à l'intérieur du logement (3). Cela permet d'éviter ce qu'on appelle des « points chauds » et d'obtenir simultanément une distribution plus uniforme des températures lorsqu'une surface extérieure (12, 13, 14, 15) du ou des tubes (5 - 10) présente un bossage (16, 17, 18), de telle manière que le premier flux de matières (4), après avoir pénétré dans le logement (3), est versé de manière sensiblement uniforme dans la zone du fond (21) et réparti de façon homogène sur les canaux d'écoulement (24).
