Abstract: We study the influence of $N$ extended heat sources at external boundaries on the nonaxisymmetric temperature distribution on profiled polar-orthotropic ring plates and take into account heat exchange with the external environment. The solution of the stationary heat conduction problem for anisotropic annular plates of a random profile is resolved through the solution of the corresponding Volterra integral equation of the second kind. The formula of a temperature calculations in anisotropic annular plates of an random profile is given. The exact solution of stationary heat conductivity problem for a reverse conical polar-orthotropic ring plate is recorded. The temperature distribution in such anisotropic plate from $N$ extended heat sources at its outer border is more complex than in the case of temperature distribution from $N$ point heat sources at their external border.

Keywords: polar-orthotropic annular plate; temperature; stationary equation of heat conductivity; Volterra integral equation of the second kind; reverse conical ring plate.
