Multiphysical Field Analysis of the Anode for a 2 450 MHz/15 kW Continuous-wave Magnetron
The heating condition of magnetron anode is analyzed briefly.The calculation method for the working end face temperature of the anode blade in a fan-shaped cavity is derived,and the electromagnetic thermal fluid-solid multi-physics field numerical simulation on the anode for a 2 450 MHz/15 kW continuous-wave magne-tron is conducted.The influence of cooling water flow rate on the temperature field and thermal deformation of the magnetron,as well as the influence of the internal temperature distribution of the anode on the frequency drift and quality factor of the magnetron are analyzed,providing some references for the production and use of magnetrons.
