Abstract

VENTILADOR DE HÉLICE. Um ventilador de hélice inclui uma pluralidade de lâminas (14) que se estende para fora na direção radial de rotação a partir da superfície periférica externa do centro cilíndrico (12). Um anel (16), provido de modo a circundar a pluralidade de lâminas (14), é conectado a cada ponta da lâmina (20) das lâminas (14). Cada lâmina (14) apresenta uma primeira porção (30), que é provida no interior na direção radial de rotação e cuja altura axial em um local de arqueamento máximo (X) é substancialmente constante, e uma segunda porção (32) que é provida no exterior na direção radial de rotação e cuja altura axial no local de arqueamento máximo (X) aumenta em direção à ponta da lâmina (20).
