Abstract

Viene descritta una ventola centrifuga per la ventilazione ed il riscaldamento d'autoveicoli, del tipo comprendente un semiguscio (15) di supporto e contenimento del motore (14) sul cui albero è calettato il mezzo (13, 13') di una girante (10) centrifuga a configurazione sostanzialmente cilindrica, dotata di palettature (11) periferiche e di superfici (12, 22, 23; 30, 32) di collegamento delle palettature (11) al mozzo (13, 13'). Semiguscio (15) e girante (10) sono racchiusi da una coclea (17) provvista di presa d'aria (18), che viene aspirata attraverso aperture frontali della girante (10), e di mandata (19) dell'aria dalla girante (10) all'abitacolo del veicolo. Nelle superfici (12, 22, 23,; 30, 32) di raccordo tra mozzo (13, 13') e girante (10), sono ricavate ulteriori palette (21, 31) che individuano una seconda ventola coassiale alla prima e solidale con essa che agisce fra l'interno del semiguscio (15) e le palettature (11) della girante (10).
