Radial fan e.g. for high-speed radial fan, has blower wheel, housing which receives rotor and stator of electrical drive of blower wheel shaft and cooling system

摘要

#CMT# #/CMT# The radial fan (1) has a blower wheel (8), a housing (2) which receives a rotor (6) and a stator (5) of an electrical drive (4) of the blower wheel shaft (7), and a cooling system. Paths (30, 37) for two cooling mediums (Ki, K2) are provided in the housing. The second cooling medium is cooled by the first cooling medium by means of the housing. The paths are separated from each other by intact material walls (40) of the housing. #CMT#USE : #/CMT# For high-speed radial fan #CMT#ADVANTAGE : #/CMT# Provides radial fan in terms of cooling system required #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows a schematic view of the invention. 1 : Radial fan 2 : Housing 4 : Electric drive 5 : Stator 6 : Rotor 7 : Blower wheel shaft 30, 37 : Paths 40 : Walls Ki, K2 : Cooling mediums.
