This patent describes an internal combustion engine having a structure subject to high heat flux; a cooling circuit for removing heat from the engine comprising: (a) a coolant jacket formed about the structure, the coolant jacket being arranged to receive coolant in liquid form and discharge same in gaseous form, (b) a radiator in which the gaseous coolant produced in the coolant jacket is condensed to its liquid form, and (c) a vapor transfer conduit leading from the coolant jacket to the radiator for transferring gaseous coolant from the coolant jacket to the radiator; a device associated with the radiator for varying the rate of heat exchange between the radiator and a cooling medium surrounding the radiator; a liquid coolant return conduit leading from the radiator to the coolant jacket for returning coolant condensed to its liquid state in the radiator to the coolant jacket; a reservoir the interior of which is maintained constantly at atmospheric pressure; and valve and conduit means for selectively interconnecting the reservoir and the cooling circuit.
