Abstract
A CT scanner comprises an x-ray window mounted on an x-ray tube, a cooling fluid circulation line, and a cooling fluid return line. A cold-plate is operatively mounted on the x-ray tube around the x-ray window. The cold plate includes an elongated shell and corrugated fins for rapidly removing heat from the x-ray window. The circulation line is in fluid communication with an inlet of the cold-plate, a cooling fluid reservoir defined between the x-ray tube and a surrounding housing, and a heat exchanger. The return line is in fluid communication with an outlet of the cold-plate, the cooling fluid reservoir, and the heat exchanger. A pump circulates the cooling fluid through the heat exchanger, the suction and return lines, the cold-plate, and the x-ray tube housing.
