Abstract

"VENTOINHA DE FLUXO AXIAL, ADAPTADA A INFLUXO, DE ALTA EFICIêNCIA". A presente invenção refere-se a uma ventoinha de fluxo axial eficiente que compreende um cubo central, uma pluralidade de lâminas, e um aro, e é projetado para operar em uma blindagem de proteção e induzir fluxo através de um ou mais permutadores de calor em um conjunto de resfriamento de motor automotivo, por exemplo. As lâminas da ventoinha possuem uma distribuição radial de proporção de passo que fornece alta eficiência e baixo ruído no campo de fluxo não uniforme criado pelo permutador(es) de calor e blindagem de proteção. A lâmina não possui arrasto, ou é arrastada para trás (isto é oposta à direção de rotação) na região entre a localização radial r/R = 0,70 e a ponta (r/R = 1,00). A proporção de passo de lâmina aumenta da localização radial r/R = 0,85 para uma localização radial entre r/R = 0,90 e r/R = 0,975, e então diminui para a ponta da lâmina.
