Abstract

JATO-VENTILADOR PARA TÚNEIS DE VENTILAÇÃO, SISTEMA DE JATO-VENTILADOR E MÉTODO. A invenção se refere a um jato-ventilador para ventilação de túneis, em particular túneis rodoviários, a um sistema de jato-ventilador e a um método para a produção de um jato-ventilador para ventilação de túneis. Em particular, a invenção se refere a um jato-ventilador para ventilação de túneis, em particular túneis rodoviários, compreendendo uma unidade de ventilador (106) para gerar um fluxo de ar, um amortecedor de ruido (110, 130) disposto na unidade de ventilador (106), com uma porção proximal (112) e uma porção distal (116) adjacente à porção proximal (112), caracterizada por a porção distal e a porção proximal estarem em ângulo (120, 122) uma com a outra.JET-FAN FOR VENTILATION TUNNELS, JET-FAN SYSTEM AND METHOD. The invention relates to a jet fan for tunnel ventilation, in particular road tunnels, a jet fan system and a method for producing a jet fan for tunnel ventilation. In particular, the invention relates to a jet fan for tunnel ventilation, in particular road tunnels, comprising a fan unit (106) for generating an air flow, a noise damper (110, 130) arranged in the ventilator (106), with a proximal portion (112) and a distal portion (116) adjacent to the proximal portion (112), characterized in that the distal portion and the proximal portion are at an angle (120, 122) to one another.
