A safety device for an X-ray unit comprises an X-ray tube protected by a casing and cooled by a fluid circulating between the tube and the casing. This device is aimed at preventing any excess pressure of the cooling fluid in the casing. It comprises a rigid, hermetically sealed and vacuum-tight cavity connected to the circuit of the fluid by a hydraulic connector with a high flow rate, designed to open mechanically and automatically under the effect of the fluid, by a pressure that exceeds a predetermined threshold.

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.
