Abstract
A heating unit for a vehicle features a radial fan () having a housing (), which housing has an air inlet () and an air exit opening (). The heating unit has an air-directing device () that guides an air flow in a pressure chamber () of the housing () to the exit opening (). Arranged in the housing () is a radial fan wheel () that serves to generate a flow from the air inlet () via the pressure chamber () to the air exit opening (). Also provided is an electrical heating element, e.g. a PTC (Positive Temperature Coefficient) heating element (), that serves to transfer heat to the air flow generated by the fan. Air-directing elements () are provided between the exit opening () and the heating element (), in order to generate an air flow having a more uniform () velocity distribution.
