Various technologies described herein pertain to a sensor for an autonomous vehicle that includes one or more heat dissipation features. A sensor includes a top cover and a bottom cover, where the top cover and the bottom cover form at least a portion of a casing of the sensor. The sensor includes a coldplate, a first printed circuit board, and a second printed circuit board. A top side of the first printed circuit board is coupled to the top cover and a bottom side of the first printed circuit board is coupled to a top side of the coldplate. A top side of the second printed circuit board is coupled to a bottom side of the coldplate and a bottom side of the second printed circuit board is coupled to the bottom cover. Various features described herein enhance heat transfer from components on the first and second printed circuit boards.

Heat dissipation features of autonomous vehicle sensor

Various technologies described herein pertain to a heat spreader for an autonomous vehicle computing device. The heat spreader includes a top surface, a bottom surface, and a side surface. The top surface of the heat spreader is thermally conductive. The top surface of the heat spreader includes a section that is sized and shaped to align with a heat generating component (e.g., on a printed circuit board assembly). The top surface of the heat spreader is configured to receive heat from the heat generating component. The bottom surface of the heat spreader includes externally integrated fins. The heat spreader is configured to dissipate the heat from the heat generating component such that the heat from the heat generating component flows from the top surface to the externally integrated fins on the bottom surface.
