Abstract

um ventilador axial (5) apresenta um eixo (r) de rotação e compreende um cubo que compreende uma parede de fundo (16) e uma parede lateral (17) que se estende a partir da parede de fundo (16) e apresenta uma borda periférica (18) no lado oposto em relação à parede de fundo (16) ao longo do eixo (r) de rotação; o ventilador compreende uma pluralidade de pás de hélice (15) que se estendem a partir da parede lateral (17) externamente ao cubo (14) e ao menos uma aleta (19) internamente ao cubo (14) e compreendendo uma porção de extremidade (20) que se projeta axialmente para além da parede de fundo (16) e da parede lateral (17), formando uma estrutura conformada em copo do cubo (14), o ventilador compreendendo uma porção de extremidade (20) que se projeta axialmente para além da borda periférica (18) externamente ao cubo (14).
