Abstract
The disclosure concerns X-ray tubes. To obtain greater temperature stability of an X-ray tube, a substance is placed in the circulation space of the cooling fluid of the tube. The latent heat of fusion of this substance is used so that it melts during the examination stage in absorbing heat, and gets solidified during the resting stage. The disclosure is applicable to X-ray tubes.
Claims9
An improved X-ray tube cooling apparatus for cooling an X-ray tube surrounded by a sheath, the sheath and tube defining a space for the flow of a cooling fluid in communication with a cooler, the apparatus comprising the combination of
- a casing in said space in heat exchange relationship with the cooling fluid, and
- a substance in said casing selected to have a latent heat of fusion which melts and absorbs heat during X-ray generating operation of said tube and solidifies during periods between generation of X-rays.
