Abstract:

An x-ray housing can include a tubular unitary body having an external fin array adjacent to an internal fin array through a heat exchanger portion of the unitary body, the internal fin array being on a luminal surface of a housing lumen of the unitary body. The external fin array can extend from a first end of the housing to a second end of the housing. The external fin array may be at a discrete and defined location, and extend around only a portion (e.g., 25%) of a circumference or external surface of the housing. The internal fin array can extends from the first end of the housing to an arced manifold recess at the second end of the housing, and be located in a finned recess that is adjacent to and dimensioned correspondingly with the external fin array.
