HEAT EXCHANGER SYSTEM FOR A VEHICLE

摘要

A heat exchanger system for a vehicle includes at least one heat exchanger, a centrifugal fan assembly for improving the flow of air through the at least one heat exchanger, the fan assembly including a rotatably mounted impeller with a plurality of impeller blades, and a rotatable inlet shroud for guiding the air flow entering the impeller; and a stationary inlet shroud located between the at least one heat exchanger and the fan assembly and configured for directing air exiting the at least one heat exchanger towards the rotatable inlet shroud of the fan assembly. The fan assembly further includes a stator with a plurality of stationary stator blades located radially or semi-radially outside the impeller for conversion of fluid dynamic pressure to fluid static pressure of the air flow.
