X-ray high-voltage generator with an oscillating heat pipe

A two-phase cooling system for an X-ray high-voltage generator of an X-ray generation device, the two-phase cooling system comprising:

• a heat sink block spatially surrounding a cooling duct loop, the cooling duct loop being at least partially filled with a working medium, and the cooling duct loop being configured to act as an oscillating heat pipe, the heat sink block including
• a material containing a polymer, and
• a multi-layered printed circuit board configured for electrical supply of a heat source of the X-ray generation device, at least two conductor path planes of the printed circuit board being conductive and a diffusion duct in a permeable conductor path plane between the at least two conductive conductor path planes being between the at least two conductive conductor path planes, wherein opposing permeable ends of the diffusion duct are spaced apart from one another such that the diffusion duct is fluid-tight as a result of a length of the diffusion duct;
• and
• a heat sink coupled to the heat sink block, the heat sink configured to dissipate heat from the heat source.
