Cooling device for arrangement in or at wheel hub motor of motor car for cooling electric power train, has fan supplying cooling air to power train, and centrifugal separator separating particles from cooling air

摘要

#CMT# #/CMT# The device (1) has a fan (2) supplying cooling air to an electric power train of a motor car. A centrifugal separator (3) separates undesired particles (7) e.g. dirt particles, from the cooling air. The separator comprises a tangential inlet region (4), a cone-shaped separation section and/or a collecting container (6) for separating the particles. The container comprises a closable aperture and a paper filter. The container is formed as a plastic injection molded part. The separator comprises magnets and/or magnetic particles, which are arranged in or on a wall of the separator. #CMT# : #/CMT# An independent claim is also included for a motor car comprising a wheel hub motor. #CMT#USE : #/CMT# Cooling device for arrangement in or at a wheel hub motor of a motor car (all claimed), for cooling an electric power train. Can also be used for an electrically propelled motor car. #CMT#ADVANTAGE : #/CMT# The centrifugal separator separates the particles from the cool air, thus ensuring that undesired particles such as dirt particles and water drops, are not passed into components of the power train through the cooling air while performing maintenance-free operation of the device. The collection container comprises the closable aperture that allows manually or automatically emptying the collecting container when required, so that the device is operated in a user-friendly manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a cooling device. 1 : Cooling device 2 : Fan 3 : Centrifugal separator 4 : Tangential inlet region 6 : Collecting container 7 : Undesired particles.
