Title:
COOLING SYSTEM FOR AN X-RAY SOURCE
Document Type and Number:
WIPO Patent Application WO2000019782
Kind Code:
A9
Abstract:
The present invention is directed to a cooling system and apparatus for use in radiographic devices having high output x-ray tubes. In operation, the x-ray tube generates large amounts of heat that must be removed so as to prevent damage to the tube. In the present invention, the x-ray tube is disposed within an x-ray tube housing that is connected within a closed fluid circuit through which circulates a coolant fluid. The fluid circulates through the x-ray tube housing and absorbs heat dissipated by the x-ray tube. Also connected within the closed fluid circuit is a heat exchange which cools the coolant fluid before it is recirculated back to the x-ray tube housing. Also connected within the closed fluid circuit is a centrifugal pump which continuously circulates the coolant fluid between the x-ray tube housing and the heat exchange device. The pump includes as an integral part a deformable bellows that accommodates any volume changes with the closed fluid system due to increases in temperature.
