Cooling system for automotive engine or the like
This patent describes an internal combustion engine a structure subject to high heat flux, and a cooling system for removing heat from the structure, the cooling system comprising: a cooling circuit including: a coolant jacket formed about the structure and into which coolant is introduced in liquid form and permitted to boil; a radiator in which gaseous coolant is condensed to its liquid state; a vapor manifold communicating with the coolant jacket; a vapor transfer conduit leading from the vapor manifold to the radiator; separation means disposed in the vapor transfer conduit for separating liquid and gaseous coolant, the separation means including a drain port; a first conduit interconnecting the drain port and the coolant jacket; a drain pump disposed in the first conduit for inducting coolant from the drain port and for pumping same into the coolant jacket; a second conduit leading from the coolant jacket to the first conduit at a location intermediate of the drain port and the pump; and coolant return means for returning liquid coolant from the radiator to the coolant jacket in a manner to maintain the structure immersed in a predetermined depth of liquid coolant.
