COLD-PLATE WINDOW IN A METAL-FRAME X-RAY INSERT

摘要

A CT scanner comprises an x-ray window (32) mounted on an x-ray tube (26), a cooling fluid circulation line (51), and a cooling fluid return line (53). A cold-plate (40) is operatively mounted on the x-ray tube (26) around the x-ray window (32). The cold plate (40) includes an elongated shell (44) and corrugated fins (42) for rapidly removing heat from the x-ray window (32). The circulation line (51) is in fluid communication with an inlet (46) of the cold-plate (40), a cooling fluid reservoir (59, 61) defined between the x-ray tube (26) and a surrounding housing (22), and a heat exchanger (D). The return line (53) is in fluid communication with an outlet (48) of the cold-plate (40), the cooling fluid reservoir (59, 61) and the heat exchanger (D). A pump circulates the cooling fluid through the heat exchanger (D), the circulation and return lines (51, 53), the cold-plate (40), and the x-ray tube housing (32).
