Abstract
The centrifugal blower and its fan housing has a wall element (18) containing a cooling coil (20) and forms a guiding and convection path (24) for an airflow produced by the fan impeller (10). The wall element extends peripherally around the fan impeller. The cooling coil has a channel (22) extending around the impeller and equipped with a fluid inlet and fluid outlet at the same end of the wall element, or at each end.
