Abstract

VENTILADOR AXIAL DE ALTA EFICIêNCIA. Um ventilador axial (1), girando em um plano (XY) em torno de um eixo geométrica (2) compreende um cubo central (3), uma pluralidade de lâminas (4) que possuem uma raiz (5) e uma ponta (6), as lâminas (4) sendo delimitadas por uma borda de condução cóncava (7) cuja projeção no plano de rotação (XY) do ventilador é definida por dois segmentos de arco circular, e uma borda de cauda convexa (8), cuja projeção no plano de rotação (XY) do ventilador é definida por um segmento de arco circular; as lâminas (4) são feitas a partir de seções com perfis aerodinâmicos se estendendo relativamente na direção da linha de centro destas, provendo uma boa taxa de fluxo e pressão de ar em relação às dimensões totais do ventilador.
