However, quite often the heat losses though the joints of the metal parts of the chamber cover are underestimated. Numerical analyses can help in an effort to estimate the thermal fields and the resulting heat losses. However, the main problem for such analyses is a realistic specification of thermal boundary conditions especially in case of heat convection. In this paper, an alternative way of setting of convection boundary condition is proposed. Instead of strict specification of convection parameters, which are very difficult to estimate, it is proposed to incorporate a simple thermal boundary layer based only on heat conduction. By this modification no boundary conditions need to be prescribed right on the surface of the analyzed structure and the resulting temperature distribution on the surface has more freedom to classify the actual design of the analyzed structure in particular locations.
