Abstract
A heat exchanger, together with one or more associated fans, is positioned on the rotating gantry frame in order to cool the x-ray tube of a CT imaging system. An air deflector is positioned on or adjacent to the heat exchanger in order to prevent recirculatoin of heated air in the ganty.
Claims9
A computed tomography (CT) imaging system comprising a gantry member, said gantry member having a rotating frame member;
- an x-ray tube positioned on said frame member;
- a heat exchanger positioned on said frame member adjacent said x-ray tube and adapted to cool said x-ray tube;
- at least one fan member positioned adjacent said heat exchanger and adapted to flow air through said heat exchanger;
- and
- an air deflector member positioned on said heat exchanger for preventing recirculation of heated air through said fan member;
- said heat exchanger having an upper perimeter surface, a lower perimeter surface, a first end perimeter surface and a second end perimeter surface, and said air deflector member being positioned on said upper perimeter surface;
- said upper perimeter surface and said lower perimeter surface each having a curved configuration;
- said air deflector member having a curved configuration substantially the same as said curved configuration of said upper perimeter surface and positioned to extend in a direction substantially parallel to the axis of rotation of said fan member.
