Claim Text:
1. A heat sink for cooling a first component comprising: a thermal contact surface for conducting heat from the first component ; a thermal dissipation structure for conducting heat away from the thermal contact surface and dissipating heat into a directed airflow; and an air channel for diverting a portion of the directed airflow toward a second component to cool the second component , wherein the second component is not in direct thermal contact with the thermal contact surface or the thermal dissipation structure when the heat sink is deployed, and wherein an internal diameter of the air channel is comparatively narrower at an air exit point than an internal diameter of an air entry point of the heat sink to increase a velocity of the portion of the directed airflow at the air exit point relative to a velocity of the directed airflow at the air entry point.
