Abstract: The present invention is directed to a radiographic apparatus that utilizes a single integral housing for providing an evacuated envelope for an anode and cathode assembly. The integral housing provides sufficient radiation blocking and heat transfer characteristics such that an additional external housing is not required. The integral housing is air cooled, and thus does not utilize any coolant. In addition, the integral housing is insulated with a potting material, which electrically insulates the integral housing and its components, and also limits the amount of noise emitted from the housing during operation. In an alternative embodiment, enhanced thermal and electrically insulating properties are achieved through the use of a potting material disposed in selected areas of the tube interior. The potting material cooperates with optimized airflow through the tube assembly to effectively and continuously remove heat therefrom.

Abstract translation: 本发明涉及一种放射线照相设备，该放射照相设备利用单个整体式外壳来为阳极和阴极组件提供抽真空的外壳。 整体外壳提供足够的辐射阻挡和传热特性，使得不需要额外的外壳。 整体外壳是空气冷却的，因此不使用任何冷却液。 此外，一体式外壳用封装材料绝缘，该封装材料使整体外壳及其部件电绝缘，并且还限制了在操作期间从壳体发出的噪声量。 在替代实施例中，通过使用设置在管内部的选定区域中的灌封材料来实现增强的热和电绝缘性能。 灌封材料通过管组件与优化的气流协同工作，以有效且连续地从中除去热量。
