Abstract

The invention relates to an electronic system (10) having a heat transfer device (13). The invention also relates to a vehicle, in particular a motor vehicle, in which such an electronic system (10) is used. The electronic system (10) comprises a housing (11), an electronic component (12) arranged in the housing (11), and a heat transfer device (13) for transferring heat from the electronic component (12) to the housing (11). The heat transfer device (13) has at least one flexible comb-like or brush-like heat coupler (14, 15) for heat transfer by means of heat conduction.

Description

technical field [0001] The invention relates to an electronic system with a heat transfer device. The invention also relates to a vehicle, in particular a motor vehicle, in which such an electronic system is used. Background technique [0002] Many sensors are installed in today's motor vehicles, which are used, for example, for safety functions, assistance functions or cruise control functions. Examples of such sensors are radar sensors, lidar sensors, ultrasonic sensors or cameras. [0003] In high ambient temperatures, the sensor may have to be tuned or completely shut down in order to protect the internal electronics from overheating. As a result, it may occur that safety functions, assistance functions or cruise functions must be deactivated. To avoid this, the sensor must be cooled or the heat generated must be dissipated by suitable measures. [0004] In this regard, DE 11 2014 005 550 T5 describes a heat transfer device which couples a heat-generating element wit...
