Abstract

Fin diffuser device for tubular heating elements, especially for electric resistance heating, characterized by the fact that it consists of at least one profiled element that extends longitudinally along the heating tube that contains at least partially in its middle part, and because it has on both sides fins that extend in the opposite direction in the same plane and cut at least part of its width into fins, said fins presenting an inclination in relation to the said plane of the wings.
