Abstract

Un ventilador centrífugo que comprende: un impulsor centrífugo (4) que puede rotar alrededor de un eje de rotación (R); un motor de accionamiento (3) del impulsor centrífugo (4); una carcasa (2) que comprende una parte central (18) para alojar el motor (3) y el impulsor centrífugo (4) y un canal de salida tangencial (18) en comunicación con la parte central (17), la carcasa (2), que tiene una abertura de entrada (15) en la parte central (17) y una abertura de salida (16) en el canal de salida tangencial (18), un sistema (4, 14, 28, 29) para refrigerar el motor (3) que comprende el impulsor (4) y un canal de ventilación (30, 31), que funciona entre el canal de salida tangencial (18) y la parte central (17) para generar un flujo de aire de refrigeración, el ventilador caracterizado por que el sistema de refrigeración (4, 14, 28, 29) comprende un collar (28), integrado con el impulsor centrífugo (4) que se extiende axialmente desde el impulsor centrífugo (4) alrededor del motor (3) y una pluralidad de palas radiales (29) soportadas por el collar (28) y orientadas hacia el motor (3) para generar una componente tangencial de enfriamiento que se combina con el flujo de aire de refrigeración generando como resultado un vórtice RF helicoidal alrededor del motor (3).

sellados, que funcionan bien en condiciones ambientales duras, también con electrónica de accionamiento integrada dentro.
El sistema de refrigeración descrito permite extender el la vida útil del ventilador hasta más de 30 000 horas de trabajo, 5 en comparación con ventiladores de la técnica anterior.
Las soluciones propuestas permiten la maximización de la refrigeración del motor que acciona el impulsor, la minimización de las fuentes de ruido de dinámica de fluidos y, al mismo tiempo, la minimización de los costes para los mismos niveles de rendimiento, evitando la adopción del conducto de conexión entre la salida del ventilador y la
10 carcasa del motor.
La adopción del canal de aspiración anular dentro de la carcasa del ventilador (componente axial) permite que se reduzcan tanto el ruido del aire debido a la dinámica de fluidos como las vibraciones en comparación con las soluciones de la técnica anterior.
