Abstract

L'invention concerne des éléments rayonnants haute efficacité de type 'Romradiatoare' pour des échangeurs thermiques conçus pour des moteurs à combustion interne, du matériel de climatisation, des installations de chauffage central, des équipements industriels, et pour d'autres applications. Cette invention permet de fabriquer des échangeurs thermiques avec un niveau de puissance élevé, grâce à l'utilisation d'éléments rayonnants dont le fluide intérieur suit un circuit en forme de U, ce circuit étant fabriqué à base de tuyaux coudés de forme identique (1). Ces tuyaux, qui présentent une section transversale circulaire dans la zone arrondie selon un certain rayon, présentent également des parties non circulaires, c'est-à-dire par exemple elliptiques, ovales, ou ovales aplaties, au niveau des parties coudées qui sont profilées après avoir été cintrées, afin d'être en contact direct avec les ailettes (2). Cette invention concerne également un procédé de fabrication d'échangeurs thermiques, ce procédé s'appuyant sur une nouvelle méthode permettant de fabriquer les tuyaux (1) qui forment les éléments rayonnants de type 'Romradiatoare' susmentionnés, par un profilage de ces tuyaux après leur cintrage.
