Patent ·
OSTI ID:6793308
This patent describes an internal combustion engine having a structure subject to high heat flux a cooling system comprising: a coolant jacket disposed about the structure and into which coolant is introduced in liquid form, permitted to boil and discharged in gaseous form; a radiator in fluid communication with the coolant jacket which receives coolant vapor produced therein and condenses it to its liquid form. The radiator includes a small collection vessel disposed at the bottom thereof; a reservoir in which coolant is stored, the reservoir being fluidly interposed between the collection vessel of the radiator and the coolant jacket. The reservoir is sized so as to contain sufficient liquid to fill the radiator but insufficient to fill the radiator and the coolant jacket; means for returning condensate from the radiator to the coolant jacket in a manner which maintains the level of liquid coolant in the coolant jacket at a predetermined level; a first temperature sensor disposed in the radiator; a second temperature sensor disposed in the coolant jacket; a device associated with the radiator.
