摘要： An x-ray tube assembly (1) includes a cathode housing (30) which has a neck connected to a frame (14) of the x-ray tube assembly. An anode (10) is positioned within an evacuated chamber defined by the frame. To reduce overheating of the neck by backscattered electrons, a cooling collar (70, 70′, 70″) is positioned around the neck of the cathode housing. Cooling fluid enters the collar through a fluid inlet tube (72, 72′, 72″). A cover member (110, 110′, 110″) of the collar includes a wall (118, 118′, 118″) which defines an aperture (126, 126′, 126″) sized for receiving the neck of the cathode housing. Cooling fluid flows around an interior annular flow path (152, 152′) defined within the cover member and leaves the cover member through the aperture or associated notches. In this way, stagnation of the flow is minimized.

摘要： 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.

摘要： A cooling oil circuit (D) circulates cooling oil over an x-ray tube absorbing its waste heat. A refrigeration circuit (E) then cools the cooling oil. A heat buffer (52) absorbing peak heat loads from the cooling fluid when the x-ray tube is generating x-rays. Valves (58, 60) regulate a relative amount of cooling oil entering the heat buffer to increase heat transfer efficiency. The heat buffer enables the system to handle peak heat loads with a smaller, more condensed refrigeration system, by absorbing heat during operation of the x-ray tube and releasing heat between operations.

摘要： An x-ray tube (1) includes a heat shield (130) which intercepts heat radiating from an anode (10), thereby reducing the temperature of a bearing assembly (62). The heat shield includes outer and inner concentric cylinders (132, 134) spaced from each other by a vacuum gap (138). The heat shield and a stationary portion (114) of the bearing assembly are both connected to a cold plate (150) so that heat is not conducted from the cylinders to the bearing assembly but is instead carried away by the cold plate to the surrounding cooling oil.

摘要： A housing (30) surrounds at least a portion of an x-ray tube (1). A cooling system (32, 32′) supplies a cooling liquid through the housing. The cooling system includes a pump (40, 40′) and a flow sensor system (60, 60′) which measures a pressure difference across the pump. A processor (80, 80′, 82, 82′) determines a cooling fluid flow rate from the pressure difference. A controller (81, 81′, 82, 82′, 107) limits operation of the x-ray tube based on the cooling fluid flow rate and a measured temperature of the cooling fluid to prevent x-ray tube overheating while minimizing cooling time between x-ray tube operations.
