Electronic built-in system

Abstract

An electronic built-in system for installation in a support structure mounted in a passenger compartment of a vehicle. The system includes at least one electronic module and a housing for receiving the electronic modules. The housing is mounted to the support structure of the vehicle and includes a front control panel with operating elements for operating the electronic system. The front control panel faces the passenger compartment. A cooling unit is provided in the housing for guiding cooling air through the housing for cooling the electronic modules. At least one first opening in an outer wall portion of the housing supplies cooling air to the housing. At least one second opening in an outer wall portion of the housing removes the cooling air from the housing. The first and second openings are arranged at different wall portions of the housing, which are separated from the passenger compartment by the support structure when the built in system is installed in the support structure.
