Abstract

A device (4) comprises a container (40) for a liquid coolant (41) that is disposed between the axis (1) and the surface (30) facing the axis to co-rotate with the surface. The device is further provided with an atomizer nozzle (42) of the container, facing the surface, from which the coolant is discharged during rotation of the container due to the centrifugal force (F) acting upon the coolant of the container in the form of an atomized jet (43) that strikes the surface. The device cools a surface of an electronic device (3) that runs hot, the electronic device supplying the X-ray source of a computer tomograph with power and rotating about the axis of the gantry (2) of the tomograph.
