the present invention is a two - phase liquid cooling system that cools a plurality of electronic components connected in parallel . a pump delivers a cooling fluid , as a liquid , to a supply manifold wherein it splits into distinct branch lines . preferably , the branch lines feed coolant to individual spray modules . the liquid coolant removes heat from the components to be cooled . the resulting liquid and vapor mixture exit the spray modules via a plurality of return branches . each individual return branch feeds into a return manifold at an acute angle . the angular transitions between the return branches and the return manifold provides low manifold losses and a more efficient system .
