Abstract:
1. A method of cooling a heat source with a cooling circuit, comprising: circulating a first liquid stream through the heat source of the cooling circuit, the heat source transferring heat to said first liquid stream, wherein at least a portion of said first liquid stream vaporizes for providing a vapor stream and a second liquid stream at an outlet of the heat source; circulating said vapor stream and said second liquid stream to a vapor separator that separates said vapor stream from said second liquid stream; accelerating said separated vapor stream to supersonic velocity with an accelerating unit; introducing an inlet liquid stream to said supersonic vapor stream, wherein said supersonic vapor stream transfers momentum to said inlet liquid stream for producing an outlet liquid stream; circulating said outlet liquid stream through a first heat exchanger for transferring heat therefrom, thereby reducing a temperature of said outlet liquid stream; and circulating said outlet liquid stream to the heat source, wherein the heat source is a fuel cell stack.
