Patentradars sammanfattning

The invention discloses a heat sink unit whose bottom side incorporates one or more profiled surfaces, each consisting of a series of adjacent ridges and grooves, that passively channel condensed moisture away from a co-mounted electronic assembly through gravitational drainage rather than active fan-driven airflow. The bottom side also carries a heat-transferring section in direct thermal contact with the electronic assembly, while the top side bears conventional heat sink fins. The profiled surfaces are inclined at 7–45° to the horizontal and separated by dedicated moisture-collecting ridges, with ridge-to-ridge spacing of 0.5–5.5 mm and peak-to-valley depth of 0.15–0.54 mm. The concept is embodied in a complete electronic arrangement and a robotic lawnmower, ensuring reliable electronics operation even when the device is powered off.
