We have developed a high power and high speed X-ray CT helical scanner, whose rotational speed is 120rpm. Heat dissipation of the machine is about 2.5 times more than that of previous machine, hence thermal design is becoming very important item in design. Three-dimensional thermo-fluid analysis and flow visualization experiment were performed in order to understand temperature and flow field in the gantry. The results of three-dimensional thermo-fluid analysis and flow visualization led some understanding to be applied in thermal design, and served an important role as thermal design tools.
