Title (EN) COOLING FAN WITH INTEGRAL HOUSING AND IMPELLER
(FR) VENTILATEUR DE REFROIDISSEMENT AVEC TURBINE ET CARTER INTEGRÉS
Abstract: front page image
(EN)A cooling fan is disclosed. The cooling fan comprises fan blades having a primary blade component and a secondary blade component. The primary blade component produces an axial airflow. The secondary blades produce a radial airflow. The axial airflow and the radial airflow, respectively created by the primary blades and the secondary blades, combine to provide an increase axial outflow. The primary and secondary blades combine the axial and radial flows respectively created by the blades to produce an increased outflow. The design has been observed to reduce tonal noise as well.
(FR)L'invention concerne un ventilateur de refroidissement. Le ventilateur de refroidissement comporte des pales de ventilateur ayant un composant de pale primaire et un composant de pale secondaire. Le composant de pale primaire produit un écoulement d'air axial. Les pales secondaires produisent un écoulement d'air radial. L'écoulement d'air axial et l'écoulement d'air radial, créés respectivement par les pales primaires et les pales secondaires, se combinent pour former un écoulement de sortie axial augmenté. Les pales primaires et secondaires combinent l'écoulement axial et l'écoulement radial respectivement créés par les pales pour produire un écoulement de sortie augmenté. L'invention permet également de réduire tout bruit tonal.
