Abstract

Dispositif d'échangeur de chaleur en forme de tige ou de tuyau comprenant plusieurs éléments séparés d'accroissement de surface en forme de disque s'étendant transversalement par rapport à l'axe longitudinal du corps de l'échangeur de chaleur, chacun de ces éléments étant équipé de plusieurs ailettes s'étendant radialement Au moins certains des éléments sont équipés d'ailettes qui possèdent un premier secteur s'étendant dans un plan commun transversal audit axe longitudinal et ayant un bord libre, et un second secteur qui, sur l'un de ses côtés se trouve sur une ligne s'étendant radialement, reliée au premier secteur, ce second secteur présente sur son autre côté un bord libre, et est incliné par rapport au premier secteur d'un angle déterminé à l'avance, des espaces pour le passage d'un milieu étant prévus de ce fait entre chacune des deux ailettes adjacentes. Applicable aux échangeurs de chaleur.A rod-shaped or pipe-shaped heat exchanger device comprising a plurality of separate disc-shaped surface increasing elements extending transversely of the longitudinal axis of the heat exchanger body, each of these elements being provided with a plurality of radially extending fins At least some of the elements are provided with fins which have a first sector extending in a common plane transverse to said longitudinal axis and having a free edge, and a second sector which on the one of its sides is on a line extending radially, connected to the first sector, this second sector has on its other side a free edge, and is inclined with respect to the first sector by an angle determined in advance, spaces for the passage of a medium thereby being provided between each of the two adjacent fins. Applicable to heat exchangers.
