Abstract
A device is disclosed for the cooling of an X-ray tube contained in a casing, using a fluid put into forced circulation in a cooling circuit comprising a heat exchanger. The device of the invention can be used to obtain efficient cooling while, at the same time, using a small volume of fluid and a heat exchanger of smaller size than in the prior art. To this end, the cooling circuit comprises means to, firstly, store a quantity of heat accumulated by the fluid when the latter reaches a pre-determined temperature during an examination period and, secondly, to restore this quantity of heat during an idle period which follows the examination period.
