This patent describes an internal combustion engine having a structure subject to high heat flux and a cooling system for removing heat from the engine. The cooling system comprises: a cooling circuit including: a coolant jacket disposed about the structure and into which coolant is introduced in liquid form and discharged in gaseous form; a radiator in fluid communication with the coolant jacket and in which coolant vapor generated in the coolant jacket is condensed to its liquid form; and means for returning liquid coolant from the radiator to the coolant jacket in a manner which maintains the structure immersed in predetermined depth of liquid coolant; and an auxiliary circuit in fluid communication with the cooling circuit and through which liquid coolant is circulated by a circulation pump. This patent describes a method of cooling an internal combustion engine having a structure subject to high heat flux.
