On analytical study of heat transfer phenomenon in special-shape soldering iron

The work presents the results of the analytical solution of the phenomenon of heat transfer in soldering iron of a special shape. For analysis, differential equations in partial derivatives from many variables were used, where initial and boundary conditions were given, according to experimental data. Partial equations were obtained in the process of solving by the method of separating variables. The resulting finite function of coordinate variables in the cylindrical coordinate system and time is derived from the original equation.
