ABOUT SOME FEATURES OF TEMPERATURE DISTRIBUTION IN DESIGNS OF LRE DURING BRAZING
Calculation analysis of non-stationary distribution of temperature in design elements at brazing of units of LRE is presented. Results show difference both on depth of heating and time of heating elements of different thicknesses, which can be as cause of temperature difference appearance and thermal stresses in design.
Keywords: LRE, brazing units, thermal diffusivity, heat flow, temperature difference, thermal stress.
