Abstract: A cooling system including an X-ray tube, a cooling source, and a conduit carrying a fluid. The conduit has a first section disposed to extract heat from the X-ray tube and a second section disposed to have heat extracted by the cooling source. The X-ray tube heats the first section such that the fluid is evaporated from a liquid fluid into a gas fluid. The gas fluid flows from the first section to the second section to achieve equilibrium. The heat from the evaporated gas fluid is extracted from the conduit at the second section by the cooling source. The cooling source cools the second section such that the evaporated gas fluid condenses to liquid fluid. The liquid fluid is moved to the first section of the conduit by the gas fluid flowing from the first section to the second section.

Abstract: A cooling system for use with high-power x-ray tubes. The cooling system includes a dielectric coolant disposed in the x-ray tube housing so as to absorb heat dissipated by the stator and other electrical components, as well as absorbing some heat from the x-ray tube itself. To improve heat absorption from the stator and the x-ray tube, the dielectric coolant is circulated throughout the housing by a circulating pump. The cooling system also includes a coolant circuit employing a pressurized water/glycol solution as a coolant. Pressurization of the water/glycol solution is achieved by way of an accumulator which, by pressurizing the coolant to a desired level, raises its boiling point and capacity to absorb heat. A coolant pump circulates the pressurized coolant through a fluid passageway defined in an aperture of the x-ray tube and through a target cooling block disposed proximate to the x-ray tube in the x-ray tube housing, so as to position the coolant to absorb some of the heat generated at the aperture by secondary electrons, and the heat generated in the target cooling block by the target anode of the x-ray tube. The target cooling block is in contact with the dielectric fluid so that some of the heat absorbed by the dielectric coolant is transferred to the coolant flowing through the target cooling block. The heated coolant is then passed through an air/water radiator where a flow of air serves to remove some heat from the coolant. Thus cooled, the coolant then exits the radiator to repeat the cycle.

Abstract: The invention relates to an X-ray examination apparatus in which the X-ray detector 1 and the X-ray source 2 are subject to keeping the temperature constant and to cooling by way of a common cooling circuit. To this end, a cooling medium of constant temperature is applied to the X-ray detector 1 in order to make the X-ray detector 1 operate at uniform ambient temperatures. The temperature of the cooling medium, thus increased a first time, still suffices to perform cooling of the X-ray source 2. Consequently, the heated cooling medium, after application to the X-ray detector 1, is applied to the X-ray source 2 where a second exchange of heat takes place, so that at the same time the X-ray source 2 is cooled without utilizing an additional cooling circuit. This offers the advantage that relevant X-ray examination apparatus may have a simple construction, that the electronic components used in the construction have a correspondingly prolonged service life due to the constant low temperature, and that the apparatus can operate with a higher mean power as a result of the cooling.
