Abstract
A antenna module includes a telematics unit having a telematics printed circuit board and a Peltier element. The telematics printed circuit board has a first section and a second section. The first section is cooled by a forced airflow and the second section is cooled by the Peltier element.
Claims18
An antenna module, comprising:
- a telematics unit having a telematics printed circuit board and a Peltier element, the telematics printed circuit board has a first section and a second section, the first section is cooled by a forced airflow and the second section is cooled by the Peltier element, the first section is a non-NAD area and the second section is an NAD area, the telematics printed circuit board has a thermal barrier arrangement between the NAD area and the non-NAD area, the thermal barrier arrangement is at least one through-slit in the telematics printed circuit board narrowing the telematics printed circuit board at a neck.
A method for cooling an antenna module, comprising:
- providing the antenna module with a telematics unit including a telematics printed circuit board, the telematics unit or the telematics printed circuit board has a non-NAD area and an NAD area;
- and
- cooling the non-NAD area and the NAD area independently of one another if a limit temperature is exceeded.
