Title:
X線管冷却流体から熱を除去する装置
Document Type and Number:
Japanese Patent JP4063369
Kind Code:
B2
Abstract:
In an arrangement for cooling an X-ray tube mounted on the gantry of a CT system, a path of flow is established by means of conduits or the like for circulating a cooling fluid between the tube and a heat exchanger. As fluid passes through the heat exchanger, a stream of air is applied to the path of flow, by means of a radial fan, to carry heat away from the fluid. The axis of the fan is maintained in parallel relationship with the axis of the gantry, to prevent gyroscopic loading of the fan as the fan rotates about the gantry axis with the gantry. The fan comprises a device for exhausting air heated by the exchange process radially, with respect to the fan axis, to minimize fan-generated acoustic noise while maintaining good thermal performance. Fan support structure lying in the path of the exhausted air is selectively shaped to reduce air flow turbulence, and to thereby further reduce fan noise.
