Abstract

''CONJUNTO DE VENTILADOR'', adaptado para ser acionado por um acionamento de entrada (V), dito conjunto de ventildor (11) compreendendo um cubo anelar (15) fixado para girar com acionamento de entrada e compreendendo ainda uma pluralidade de pás de ventilador. A pluralidade de pás de ventilador inclui uma pluralidae de pás de ventilador internas (17) fixadas em relação ao cubo anelar (15) e estendendo-se radialmente para fora deste último e um membro de anel anelar (23) disposto em torno da pluralidade de pás de ventilador internas (17) e fixadas à extensão radialmente externa destas . Uma pluralidde de pás de ventilador externas (25) é fixada em relação ao membro de anel anelar (23) e estende-se radialmente para fora. Há um número maior de pás de ventilador externas (25) do que o de pás de ventilador internas (17), aumentando portanto a capacidade de fluxo de ar do ventilador , bem como a sua eficiência.
