Claim:
1. An apparatus comprising: one or more heat sources; a centrifugal fan unit having a hub, a plurality of blades disposed on the hub, and a motor coupled to the hub, the motor to cause the hub to rotate about an axis such that airflow proceeds outward from the centrifugal fan unit along trajectories that are perpendicular to the axis; one or more thermal transfer units having at least first portions that are coupled to the one or more heat sources and second portions that collectively at least partially surround the centrifugal fan unit, the second portions of the thermal transfer units surrounding the centrifugal fan unit comprising a plurality of fins that are collinear with tangents of a circle that is formed by outside edges of the plurality of blades of the centrifugal fan unit; a housing that encloses the heat source, the centrifugal fan unit, and the thermal transfer units; a plate that is disposed on an inner portion of a surface of the apparatus, the centrifugal fan unit mounted on the plate; and one or more holes on the surface of the apparatus near to a position of the centrifugal fan unit to enable intake airflow to proceed towards the centrifugal fan unit from the one or more holes.
