  • Patent number: 9865424
    Abstract: An X-ray inspection system of the present application is capable of blocking the effect of heat from an X-ray source, thereby making it possible to place a heat-sensitive circuit component in the same housing space as the X-ray source. The X-ray inspection system includes a housing 10 provided with an upper housing space 11, in which an X-ray source 32 housed in a cooling container 30 is placed. Due to pressure of a pump 36, a cooling medium circulates between the cooling container 30 and a heat radiating device 33, thereby suppressing the temperature rise of the cooling container 30. Since the cooling container 30 is placed in the upper housing space 11, the upper housing space 11 serves as a cooling space, suppressing the temperature rise. Therefore, heat-sensitive or heat-producing circuit components can be placed in the upper housing space 11.

  • Patent number: 7897933
    Abstract: A radiation image capturing apparatus includes a cooling mechanism for causing cooling medium to flow from a rear surface side to a radiation detector to a front surface side of radiation detector through a narrow space formed between an end of the radiation detector and a casing for housing the radiation detector. It is therefore possible to cool the narrow space, as well as regions in the vicinity of the narrow space, with the cooling medium and to discharge the cooling medium from the front surface side of the radiation detector.

  • Patent number: 7887237
    Abstract: A computed tomography apparatus has a gantry for mounting components of an acquisition system that are arranged such that they can rotate around a system axis, and a stationary part in which the gantry is supported such that it can tilt. A device for cooling the components by airflow is arranged on the gantry. The cooling device has at least one feed channel and at least one air discharge channel that are arranged between the stationary part and the gantry so that the air current introduced into the gantry via the stationary part is conducted out from the gantry into the stationary part in a directed manner after cooling the components. The direction of the air current directed from the computed tomography apparatus thus does not depend on the tilt of the gantry. Moreover, the computed tomography apparatus is designed such that cooling is achieved with low noise emission since the direct sound propagation path between the exit opening and the gantry is interrupted.

  • Publication number: 20100322374
    Abstract: A tomography apparatus has an annular channel and at least one ventilation element for the purpose of drawing off an air current flowing through the annular channel. The ventilation element contains an intake window that is located in the annular channel for the purpose of drawing off at least a portion of the air current. In order to obtain an even flow profile at an output window of the ventilation element, the intake window has a greater effective intake cross-section at both sides than at the middle. By such evening the flow profile at the output window, turbulence and air current interruptions of the air can be generally avoided, such that when operating the tomography apparatus, disrupting acoustic emissions may be reduced, or a higher air flow and thereby a greater cooling effect may be obtained.

  • Patent number: 7543987
    Abstract: An x-ray imaging system is disclosed, where one example of such a system includes a frame or other structure to which a modular cooling unit of the x-ray imaging system is attached. The modular cooling unit includes a radiator, configured for fluid communication with an x-ray tube housing, as well as one or more fans configured to cause a flow of air to pass through the radiator. In this example, the x-ray imaging system further includes a detector array arranged to receive x-rays generated by an x-ray tube insert disposed within the x-ray tube housing. In operation, the air flow caused by the fans of the modular cooling unit removes heat from coolant flowing out of the x-ray tube housing and through the radiator.
