Abstract
A thermal management device includes a heat spreader and a folded graphite sheet. The heat spreader is configured to receive heat from a heat source. The folded graphite sheet is connected to the heat spreader to receive and exhaust heat from the heat spreader. The folded graphite sheet includes a first fin, a second fin, and a segment connecting the first fin and second fin. The first fin is oriented at least partially vertically away from the heat spreader. The second fin is oriented at least partially vertically away from the heat spreader. The folded graphite sheet is continuous through the first fin, the segment, and the second fin.
