Cooling system for automotive engine or the like
This patent describes an internal combustion engine having a structure subject to high heat flux, and (a) a cooling system for removing heat from the engine comprising: a cooling circuit which includes: a coolant jacket formed about the structure, the coolant jacket being arranged to receive coolant in liquid form and discharge same in gaseous form; a radiator which fluidly communicates with the coolant jacket by way of a coolant transfer conduit and in which gaseous coolant produced in the coolant jacket is condensed to its liquid form; a return conduit leading from the radiator to the coolant jacket for returning coolant condensate from the radiator to the coolant jacket; and a return pump disposed in the return conduit, the return pump being selectively energizable to maintain a predetermined level of coolant in the coolant jacket; (b) a reservoir the interior of which is maintained constantly at atmospheric pressure; and (c) a volume control pump fluidly interposed between the reservoir and the cooling circuit for pumping coolant between the cooling circuit and the reservoir in a manner which varies the amount of coolant in the cooling circuit.
