Heatsink with adjustable fin pitch

A computer system, comprising:

• a first integrated circuit;
• a second integrated circuit that is disposed downstream relative to the first integrated circuit with respect to a cooling airflow when the computer system is in operation;
• an adjustable heat exchanger that includes:
• at least one heat pipe that is adapted to be thermally coupled to the first integrated circuit and has an evaporator portion and a first condenser portion, wherein the first condenser portion extends away from the evaporator portion;
• a first plurality of cooling fins that is attached to the first condenser portion;
• a second plurality of cooling fins;
• and
• a first movable support that is mechanically coupled to the second plurality of cooling fins and thermally coupled to the first condenser portion and moves the second plurality of cooling fins relative to the first plurality of cooling fins;
• and
• a controller that receives one or more signals that indicate at least one temperature associated with at least one aspect of the computer system, determines an adjustment to be made to the adjustable heat sink based at least on the one or more signals, and causes an actuator to move the first movable support in order to perform the adjustment.
