Patent ID: 7299647

Claim:
A narrow gap thin-film evaporative spray cooling system for cooling at least one electronic component utilizing a transversely sprayed cooling fluid, comprising: a transverse spray framework defining an at least partial perimeter around a narrow gap cavity, the narrow gap cavity including a height, a width greater than the height, and a length, disposed to house at least one electronic component to be spray cooled; a plurality of transverse atomizers integral with the transverse spray framework at a first side of the transverse spray framework, the plurality of transverse atomizers being disposed to receive cooling fluid from a cooling fluid pre-heater and to spray the cooling fluid into the narrow gap cavity transverse to the at least one electronic component; a cooling fluid outlet in fluid communication with the cooling fluid cavity, disposed to receive cooling fluid from the narrow gap cavity and route it to a transverse spray framework outlet; and further wherein a cross-sectional area of the narrow gap cavity reduces from the atomizers to the cooling fluid outlet.
