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 module. 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.

Claims

1. A system for installation in a support structure in a passenger compartment of a vehicle comprising:

at least one electronic module;

a housing for receiving said at least one electronic module, the housing being mounted to the support structure of the vehicle and comprising a front control panel with operating elements for operating the system, the front control panel facing the passenger compartment;

a cooling unit provided in the housing for guiding cooling air through the housing for cooling said at least one electronic module;

at least one first opening provided in a outer wall portion of the housing for supplying cooling air to the housing;

at least one second opening provided in an outer wall portion of the housing for removing the cooling air from the housing;

where said at least first and said at least second openings are arranged at different wall portions of the housing, the different wall portions being separated from the passenger compartment by the support structure when the built in system is installed in the support structure.

2. The system according to claim 1, where the first and the second openings are arranged at opposite wall portions of the housing.

3. The system according to claim 1 where the first and the second openings are arranged on respective side walls of the housing.

4. The system according to claim 1 where the cooling unit comprises a ventilator situated next to the second openings for removing the cooling air.

5. The system according to claim 1 where the first and the second openings are arranged on the lower portions of the respective side walls of the housing.

6. The system according to claim 1 further comprising at least one of a radio module, an audio module, a navigation module, a telecommunication module and a storage medium reading module.

7. The system according to claim 6 where at least one of the radio module, the audio module, the navigation module, the telecommunication module is arranged in the lower part of the housing, whereas the storage medium reading module is arranged in the upper part of the housing.

8. The system according to claim 1 where the cooling unit comprises cooling fins.

9. The system according to claim 8 where the ventilator is next to the wall portion having the second openings for removing the cooling air from the housing, with the cooling fins being interposed between the wall portion and the ventilator.

10. The system according to claim 1 where the support structure is a console.

11. The system according to claim 1 where the first and the second openings are arranged on sidewalls of the housing in such a way that heat generating modules are arranged in-side the housing at approximately the same height as the first and the second openings;

and

where a storage medium reading module is arranged inside the housing at a larger difference in height to the first and second openings than the heat generating modules.

22. The electronic built-in system according to claim 1 further comprising a mother printed circuit board which is arranged at the bottom of the housing.

23. The electronic built-in system according to claim 1 where the housing is a 2 DIN housing, fitting in a 2 DIN recess of the support structure.

12. An electronic built-in system of a vehicle comprising:

a housing for receiving several electronic modules, the modules comprising heat generating modules and at least one optical read module for reading out data from a removable storage medium;

a cooling unit for guiding cooling air through the housing for cooling the electronic modules;

first openings provided in an outer wall portion of the housing for supplying cooling air to the housing;

second openings provided in an outer wall portion of the housing for removing the cooling air from the housing, where the first and the second openings are arranged at the housing in such a position, that the cooling air on its way from the first openings to the second openings is predominately guided along the heat generating modules.

13. The electronic built-in system according to claim 12 where the first and the second openings are arranged on opposite wall portions of the housing.

14. The electronic built-in system according to claim 12 where the first and the second openings are both arranged at the lower parts of side walls of the housing.

15. The electronic built-in system according to claim 12 where the heat generating modules are arranged inside the housing in a lower part of the housing, where the optical read module is arranged in an upper part of the housing.

16. The electronic built-in system according to claim 12 where the cooling unit comprises a ventilator arranged next to the second openings for removing the cooling air from the housing.

17. The electronic built-in system according to claim 16 where the cooling unit comprises cooling fins, which are arranged between the wall portion comprising the second openings and the ventilator.

18. The electronic built-in system according to claim 12 further comprising a mounting unit for receiving a hard disk in the electronic built in system.

19. The electronic built-in system according to claim 18 where the mounting unit for receiving the hard disk is arranged in the lower part of the housing.

20. The electronic built-in system according to claim 12 further comprising a detachable front control panel.

21. The electronic built-in system according to claim 20 where the hard disk can be mounted to the mounting unit with the front control panel being detached.

24. A navigation system comprising an electronic built in system according to claim 12.
