BRAKING RESISTOR ARRANGEMENT IN A COMPUTED TOMOGRAPHY GANTRY

A gantry for a computed tomography device has a support structure, a pivot bearing, a rotating frame, a first braking resistor configured to electromotively brake a rotational movement of the rotating frame, and a heat conductor configured to dissipate heat from the first braking resistor. A heat co...

Beschreibung
Zusammenfassung:	A gantry for a computed tomography device has a support structure, a pivot bearing, a rotating frame, a first braking resistor configured to electromotively brake a rotational movement of the rotating frame, and a heat conductor configured to dissipate heat from the first braking resistor. A heat conductor and a pressure duct wall are interconnected to form a heat-conductor-to-pressure-duct-wall connection that is detachable, form-fitting, planar, and thermally conductive. The heat is transferrable from the first braking resistor to the airflow via the heat conductor, the heat-conductor-to-pressure-duct-wall connection and the pressure duct wall.
