Abstract

A pressurized sub-cooled water cooling option for a full-size gyrotron cavity, based on mini-channels, is developed and analyzed using the commercial computational fluid dynamics (CFD) tool STAR-CCM+. On the basis of this design, which guarantees a pressure drop below the maximum acceptable and the compliance with manufacturing constraints, we study the cooling of a representative mock-up to be experimentally tested in the near future. The solution of the conjugate heat transfer problem in the mock-up geometry is presented, aimed at assessing its thermal performance under increasing target heat load up to 24 MW/m2.
