Abstract: An apparatus for mechanically connecting a component to a gantry, comprises: a fastener fitted through a through-opening in the component, wherein the fastener is screwed to the gantry; and a spring assembly positioned on the fastener. The spring assembly includes one or more springs, wherein the one or more springs are arranged between a head of the fastener and the component. The one or more springs are compressed to generate a pretensioning that securely holds the component on the gantry. The component has a fastening portion in which the through-opening is arranged, wherein the through-opening has a tapered widening on a side facing the gantry. The fastener has a positive connecting portion, wherein the positive connecting portion is positively arranged in the tapered widening.

Abstract: A two-phase cooling system for an X-ray high-voltage generator comprises a heat sink block and a heat sink. The heat sink block spatially surrounds a cooling duct loop, wherein the cooling duct loop is at least partially filled with a working medium and is configured to act as an oscillating heat pipe. The heat sink is configured to dissipate heat from a heat source. The heat sink block includes a material including a polymer.

Abstract: An X-ray high-voltage generator comprises: a circuit arrangement having at least one power electronics circuit part, wherein the at least one power electronics circuit part is configured to form a heat source during operation; and a two-phase cooling system having a heat sink. The at least one power electronics circuit part is directly thermally coupled to the two-phase cooling system to cool the heat source at the heat sink. The two-phase cooling system has a cooling element block that spatially surrounds a cooling channel circuit. The cooling channel circuit is at least partially filled with a working medium, and is configured to act as a heat pipe.
