This patent describes an internal combustion engine: a structure subject to high heat flux a cooling system for removing heat from the structure, the system comprising: (a) a cooling circuit including: (i) a coolant jacket formed about the structure and into which coolant is introduced in liquid form and permitted to boil; (ii) a radiator in which gaseous coolant is condensed to its liquid state; (iii) a vapor manifold fluidly communicating with the coolant jacket; (iv) a vapor transfer conduit leading from the vapor manifold to the radiator; (v) means defining a liquid coolant collection section in the vapor manifold into which liquid coolant emitted from the coolant jacket is collected; (vi) means defining a drain port in the collection section; (vii) a drain conduit leading from the drain port to the coolant jacket; (viii) coolant return means for returning liquid coolant from the radiator to the coolant jacket in a manner to maintain the structure immersed in a predetermined depth; (b) a reservoir containing liquid coolant; and (c) valve and conduit means for selectively interconnecting the cooling circuit with the reservoir.
