1. An X-ray high-voltage generator for providing a high voltage for X-ray beam generation in an X-ray tube, the X-ray high-voltage generator comprising:
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, wherein
the at least one power electronics circuit part is directly thermally coupled to the two-phase cooling system to dissipate heat from the heat source at the heat sink,
the two-phase cooling system has a cooling element block,
the cooling element block spatially surrounds a cooling channel circuit, and
the cooling channel circuit is at least partially filled with a working medium, and is configured to act as a heat pipe.
