Cooling system for automotive engine or the like
In an internal combustion engine having a structure subject to high heat flux a cooling system is described comprising: 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 which receives coolant vapor produced therein and condenses it to its liquid form, the radiator including 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; a level sensor disposed in the coolant jacket, a pump which pumps liquid coolant from the reservoir to the coolant jacket through a coolant return conduit, the pump being responsive to the level sensor in a manner to maintain the level of liquid in the coolant jacket at the predetermined level; a first temperature sensor disposed in the radiator; a second temperature sensor disposed in the coolant jacket; and a device associated with one of the radiator, the coolant jacket and the reservoir, the device being responsive to one at least one of the first and second temperature sensors for controlling the pressure within the cooling system.
