A study on the cooling system of low power magnetron by using the natural convection heat transfer

This paper describes the application of natural convection cooling system for low power magnetron by calculating heat transfer and some experiments. This cooling structure is analyzed by parametric studies, for instance, the analysis by components; resonator, conductor, heat sink, etc. This article is focused on the temperature of resonator and heat sink, and the power drift of magnetrons. Also we took account of fully closed system and opened system simultaneously. This analysis is used to design some kinds of cooling systems.
