Abstract

Die Erfindung betrifft einen Ventilator zur Erzeugung eines Fluidstromes, insbesondere eines Luftstromes.The invention relates to a fan for generating a fluid flow, especially an air flow.

Aufgabe der Erfindung ist es, einen Ventilator für einen beheizbaren Fluidstrom zu schaffen, bei dem die erforderliche Energieaufnahme verringert wird.The object of the invention is a fan for a heatable fluid flow to create, in which the required energy consumption is reduced.

Ein erfindungsgemäßer Ventilator verfügt über ein Laufrad, das wenigstens eine Schaufel zum Fördern des Fluids aufweist. An wenigstens einem Teil der Schaufeln des Laufrades des Ventilators ist wenigstens ein Heizelement vorgesehen. Das Heizelement dient zum Erwärmen des Fluids während des Förderbetriebes des Ventilators.A fan according to the invention has an impeller that has at least one Has blade for conveying the fluid. On at least part of the Blading the impeller of the fan is at least one heating element intended. The heating element is used to heat the fluid during the Conveyor operation of the fan.
