Heat Sink Unit, Electronic Arrangement, and Robotic Lawnmower

Patentradars sammanfattning

Husqvarna's invention is a heat sink unit whose bottom face incorporates multiple profiled surfaces—each carrying a series of adjacent ridges and grooves—that guide condensed moisture away from the electronic assembly beneath it through gravitational drainage rather than active airflow. The profiled surfaces are inclined at 7–45° to the horizontal and separated by dedicated moisture-collecting ridges, so water migrates laterally to the periphery instead of dripping onto circuit boards or control units. The top side retains conventional heat-sink fins for convective thermal dissipation, while the bottom heat-transferring section maintains direct thermal contact with the electronics. The arrangement is targeted at robotic lawnmowers where fan-based anti-condensation measures are impractical and the unit may sit idle for extended periods.
