Control Appliance For Using In The Engine Compartment Or In The Transmission Of A Motor Vehicle And Cooling System For Such A Control Appliance

Abstract

A control device for use in the engine compartment or in the transmission of a motor vehicle. The control device has a housing comprising a housing section for a control unit. The housing also has a line section for the motor or transmission fluid. The line section is thermally coupled to the housing section for the control unit. Such a control device and a cooling arrangement therefore ensure that the electronic components in the control device are cooled such that a pre-determined temperature limit for the electronic components is not exceeded.
