Abstract

ventilador de fluxo axial. a presente invenção refere-se a um ventilador que inclui um cubo e lâminas. a primeira borda de cada lâmina está próxima de uma extremidade aberta do cubo a primeira nervura é acoplada ao cubo e substancialmenet alinhada com um primeiro plano interceptando o eixo central e uma interseção da primeira borda de uma primeira lâmina com o cubo. o primeiro plano é angularmente espaçado de um plano de referência interceptando o eixo central e uma interseção da primeira borda da segunda lâmina com o cubo. um espaçamento angular entre o primeiro plano e um plano de referência define um setor. uma segunda nervura é substancialmente alinhada com um segundo plano angularmente posicionado entre o primeiro plano e o plano de referência em uma localização menor que ou igual a cerca (1/nr-0,05) setores a partir do primeiro plano, em que nr é igual ao númeor de nervuras dividido pelo número de lâminas.
