Abstract

Un ventilador de caja que comprende una estructura a modo de caja que tiene una abertura delantera y una abertura trasera interconectadas para formar un conducto que pasa a través de dicha estructura, conteniendo dicho conducto un motor eléctrico y un conjunto de paletas de ventilador de gran profundidad axial y de paletas anchas, operable por el motor para girar alrededor de un eje de rotación, cuyo conjunto de paletas de ventilador está situado de manera que el centro de gravedad de dicho conjunto de paletas de ventilador está situado cerca de la abertura trasera, teniendo el conjunto de paletas de ventilador una pluralidad de paletas, cada una de las cuales tiene una configuración en un plano normal al eje de rotación, caracterizado porque la configuración comprende un cuello que une las paletas a un cubo que define el centro del conjunto, un borde delantero ligeramente convexo que se extiende desde dicho cuello, un borde más externo convexo, un borde trasero ligeramente convexo y una parte de mentón que une el borde trasero al cuello, estando dicho borde trasero fuertemente calado cerca de dicha parte de mentón estando fuertemente calado en disminución a medida que el borde más externo se aproxima a lo largo de dicho borde trasero.
