Abstract
“A cooling disk to transfer heat from an anode to a circulated coolant. The cooling disk includes an annular body that defines an aperture and includes extended surfaces. The cooling disk resides in a fluid passageway defined by the anode, and contacts the anode so as to transfer heat from the anode to a coolant circulated through the fluid passageway by an external cooling unit. The coolant passes through a coolant supply passageway which includes a converging portion that serves to accelerate the coolant as it exits the coolant supply passageway. The accelerated coolant passes through the aperture and contacts a flow diverter disposed in the fluid passageway, as well as the extended surfaces of the cooling disk, so as to remove heat therefrom. The flow diverter transmits heat from the anode to the coolant. The coolant enters the coolant return passageway and returns to the external cooling unit.”
