Abstract

Patente de Invenção para <B>"VENTILADOR DE FLUXO AXIAL"<D> Um ventilador de fluxo axial (1; 30) compreende um furo central (3; 33), uma pluralidade de pás de hélice (4; 34) que possuem uma raiz (5; 35), e uma extremidade (6; 36). De acordo com uma concretização, as pás de hélice (4; 34) são espaçadas em ângulos desiguais (<SYM>~ ?i~... ~ n?~) que podem variar em percentagens (<SYM>%) de 0.5% a 10%, comparado à configuração com igual espaçamento de ângulos (<SYM>-) para ventiladores com um igual número de pás de hélice. Preferivelmente, as pás de hélice (4; 34) são delimitadas por uma aresta convexa (7; 37), cuja projeção no plano de rotação do ventilador é definida por um segmento parabólico e uma aresta cóncava (8; 38) cuja projeção no plano rotacional do ventilador é definido por um arco circular.
