Abstract

Ventilateur tour et ventilateur portable. Le ventilateur portable comprend une soufflante centrifuge turbo (10) et un boîtier de montage (20), la soufflante centrifuge turbo étant pourvue d'une entrée d'air (101), de pales turbo (100) communiquant avec l'entrée d'air, et d'une sortie d'air (102) ; un conduit d'air de mise sous pression (103) est formé entre l'entrée d'air et la sortie d'air ; la soufflante centrifuge turbo est disposée dans le boîtier de montage, et le conduit d'air de mise sous pression est formé entre une surface interne du boîtier de montage et les pales turbo ; et lorsqu'il est en fonctionnement, un flux d'air externe est aspiré à travers l'entrée d'air au moyen de la rotation des pales de turbine, est mis sous pression au moyen des pales de turbine, et est ensuite soufflé à travers la sortie d'air. Selon le ventilateur, le volume d'air est augmenté au moyen de la soufflante centrifuge turbo, et la pression d'air est augmentée au moyen du conduit d'air de mise sous pression, ce qui permet d'obtenir un effet de soufflage d'air avec une pression d'air élevée et un grand volume d'air ; le bruit de la soufflante centrifuge turbo est commandé au moyen du conduit d'air de mise sous pression, ce qui permet d'obtenir l'effet technique du faible bruit ; et le ventilateur est plus petit en taille globale et plus sûr qu'un ventilateur à flux axial.
