  • each mixing element or pipe coil bundle requires its own collector for the heat transfer medium.
  • the pressure loss on the heat carrier side in the pipes is high because of the long lines and many pipe bends. Different lengths of the coils lead to uneven distribution of the flows on the heat transfer side and can in turn cause maldistribution on the product side.

Abstract

L'invention concerne un échangeur de chaleur à faisceau tubulaire comportant des éléments intégrés constitués de barrettes de guidage, de fenêtres et de barrettes de guidage. Lesdits éléments intégrés permettent d'obtenir un mélange permanent dans le courant de produit pendant le transfert de chaleur, ce qui empêche une mauvaise répartition et le rétromélange axial. En même temps, la voie d'écoulement est prolongée, et le transfert de chaleur se trouve ainsi amélioré. Le produit s'écoule à l'extérieur (6) d'un échangeur de chaleur à faisceau tubulaire (1) comportant une entrée (2) et une sortie (3) pour le produit, et une entrée (4) et une sortie (5) pour l'échangeur de chaleur dans les tubes (7). Les déflecteurs (ou surfaces déflectrices) (8) contenus dans un échangeur de chaleur à faisceau tubulaire sont modifiés de façon à laisser ouvertes des fenêtres (12, 13) et de telle sorte qu'au moins une barrette de guidage (10) ou (11) est montée sur le côté entrée et le côté sortie de la surface déflectrice. Lesdites barrettes de guidage s'étendent parallèlement aux axes des tubes, et se croisent. Le courant est divisé sur le côté entrée par les barrettes de guidage, et guidé dans des directions opposées aux fenêtres, où il sort ensuite sur des côtés opposés des barrettes de sortie, et est dévié.
