Title: Cooling system for automotive engine or the like

Abstract

This patent describes, in an internal combustion engine having a structure subject to high heat flux a cooling circuit for removing heat from the engine comprising: 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 in which the gaseous coolant produced in the coolant jacket is condensed to its liquid form; a vapor transfer conduit leading from the coolant jacket to the radiator for transferring gaseous coolant from the coolant jacket to the radiator; a device associated with the radiator for varying the rate of heat exchange between the radiator and a cooling medium surrounding the radiator; a liquid coolant return conduit leading from the radiator to the coolant jacket for returning coolant condensed to its liquid state in the radiator to the coolant jacket; a reservoir the interior of which is maintained constantly at atmospheric pressure; and valve and conduit means for selectively interconnecting the reservoir and the cooling circuit, the valve and conduit means including a three-way valve disposed in the return conduit and a level control conduit leading from the three-way valve to the reservoir. The three-way valve has amore » first state wherein fluid communication between the radiator and the coolant jacket is interrupted and communication between the radiator and the reservoir established, and a second state wherein communication between the reservoir and the radiator is interrupted and communication between the radiator and the coolant jacket established.« less
