Cooling device for electric power supply i.e. drive controller, of electric motor, has electrical power components positioned with positioning unit and/or heat conductively and overlying fixed at retaining surface plane at cooling device

摘要

#CMT# #/CMT# The device (1) has continuous planar retaining surfaces (3) for electrical power components (5-9) of an inverter. The components are heat conductively fixed at the cooling device at geometrically preset positions of the retaining surfaces in geometrical preset orientation. The components are positioned with a positioning unit and/or are heat conductively and overlying fixed at a retaining surface plane at the cooling device by an adjusting unit with heating conductive paste and/or by screwing, where the adjusting unit is aligned practically on a same level with the retaining surface plane. #CMT# : #/CMT# An independent claim is also included for a method for producing a cooling device. #CMT#USE : #/CMT# Cooling device for an electric power supply i.e. drive controller, of an electric motor (all claimed). #CMT#ADVANTAGE : #/CMT# The electrical power components are positioned with a positioning unit and/or are heat conductively and overlying fixed at the retaining surface plane at the cooling device by the adjusting unit with heating conductive paste and/or by screwing, where the adjusting unit is aligned practically on same level with the retaining surface plane, thus positioning of the power component in an effective manner to reduce or prevent assembly-conditioned malfunctions or damages, and facilitating manual and automatic mounting of the cooling device. The cooling device is manufactured with small manufacturing complexity, with small costs and with high mounting accuracy. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a top perspective view of a drive controller with a cooling device. 1 : Cooling device 2 : Electric power supply 3 : Retaining surfaces 5-9 : Electrical power components 10 : Screw connection.
