Abstract
A heat sink and method for gaseous cooling of superconducting power devices. Heat sink is formed of a solid material of high thermal conductivity and attached to the area needed to be cooled. Two channels are connected to the heat sink to allow an inlet and an outlet for cryogenic gaseous coolant. Inside the hollow heat sink are fins to increase metal surface in contact with the coolant. The coolant enters through the inlet tube, passes through the finned area inside the heat sink and exits through the outlet tube.
