Industrial X-ray machine

Claim 1

A completely enclosed, self-contained, cooled, industrial X-ray machine having an improved X-ray tube, power supply and heat exchanger assembly, comprising: (a) a cylindrical metallic housing of selected material, longer than said X-ray tube, a plurality of narrow longitudinal grooves with intervening narrow vanes, on the outside surface of said housing; (b) a large plurality of narrow longitudinal grooves with intervening narrow vanes, on the outside surface; these internal and external vanes extending substantially the full length of said housing except for a portion of selected length intermediate the two ends, where said vanes are cut down to a thin-walled cylinder of selected thickness; (c) a first thin-walled outer sleeve surrounding the outer edges of said outer vanes forming a plurality of external tubular longitudinal passageways along the outside surface of said housing, said outer sleeve extending from a first end of said housing almost to the second end, leaving a short length of said grooves uncovered; (d) means to support two power transformers inside said housing, one at each end, for supplying high voltage to the cathode and anode respectively, of said X-ray tube; (e) plate means to close off and seal both ends of said housing, and means to inject a selected gas at a selected pressure inside said closed housing; (f) a conventional, commercial, X-ray tube, and support means for said X-ray tube inside of and concentric with an inner thin-walled cylindrical sleeve; and means to position said inner sleeve concentrically in said housing; (g) internal fan means for circulating said selected gas inside of said inner sleeve past a first transformer, over said X-ray tube and past a second transformer, then through the annular space between said inner sleeve and said housing, back to said internal fan means; (h) external fan means for blowing external air through said longitudinal passageways outside of said housing.
