Abstract
A roof antenna module to be mounted on a vehicle roof of a motor vehicle is disclosed. The module includes an antenna unit and a control device. The control device includes a housing. The housing bounds a receptacle for electronic components of the control device. The antenna unit is arranged on a top side of the housing which is intentionally provided to face an internal side of the vehicle roof in the assembled state of the roof antenna module with the vehicle roof. At least on the top side, a flow channel of the roof antenna module for a cooling airflow is formed, which is separate from the receptacle.
Claims18
A roof antenna module to be mounted on a vehicle roof of a motor vehicle, the roof antenna module comprising:
- an antenna unit;
- a control device;
- and
- a fan comprising a fan housing and a fan wheel,
- wherein the control device comprises a housing,
- wherein the housing bounds a receptacle for electronic components of the control device,
- wherein the antenna unit is arranged on a top side of the housing, which is intentionally provided to face an internal side of the vehicle roof in an assembled state of the roof antenna module with the vehicle roof,
- wherein at least on the top side, a flow channel of the roof antenna module for a cooling airflow is formed, which is separate from the receptacle, and
- wherein the fan is coupled to the flow channel for generating the cooling airflow.
A method for cooling an interface region between an outer roof of a vehicle roof and a control device of a roof antenna module, wherein the outer roof and the roof antenna module are an integral part of a motor vehicle, the method comprising:
- activating a fan of the roof antenna module;
- suctioning air from a passenger compartment of the motor vehicle by the fan;
- introducing the suctioned air through an opening in a headliner of the motor vehicle into a flow channel of the roof antenna module for cooling airflow;
- conducting the cooling airflow through a housing of the control device up to an outlet on a top side of the housing of the control device;
- and
- conducting the cooling airflow in a flow channel section of the flow channel, which is open in the housing on the top side of the housing in such a way that the cooling airflow flows directly along an internal side of the outer roof and the top side of the housing of the control device and thereby the interface region between the internal side and the housing is cooled.
A roof antenna module to be mounted on a vehicle roof of a motor vehicle, the roof antenna module comprising:
- an antenna unit;
- and
- a control device, wherein the control device comprises a housing,
- wherein the housing bounds a receptacle for electronic components of the control device,
- wherein the antenna unit is arranged on a top side of the housing, which is intentionally provided to face an internal side of the vehicle roof in an assembled state of the roof antenna module with the vehicle roof,
- wherein at least on the top side, a flow channel of the roof antenna module for a cooling airflow is formed, which is separate from the receptacle, and
- wherein the flow channel comprises an inlet, which is formed on a bottom side of the housing.
