Abstract
The useful life of x-ray tubes is extended by filtering metal particles and other decomposition products out of the coolant fluid by filter means permanently included in the closed loop cooling fluid circuit which also includes pump means and heat exchange means.
Claims3
A radiographic apparatus including:
- an x-ray tube coupled with a closed cooling system in which a coolant fluid circulates through the closed cooling system;
- filter means permanently coupled to the closed cooling system for removing contaminants from the circulating coolant fluid;
- and circulation means within the closed cooling system for pumping the coolant fluid through the closed cooling system while the radiographic apparatus is in operation;
- wherein the filter means is assembled in parallel to a heat exchanger so that a portion of the circulating coolant fluid passes through the filter means during each full fluid circulation exchange.
