Modeling the influence of heat sinks on the structure of the temperature field of a profile heat pipe

Within the framework of a computer experiment using the finite element method, a technique has been developed graphical representation the structure of the temperature field of a heat pipe with active-type defects - heat energy sink, localized in the body between the ribs. It is shown that when the pipe start-up mode is implemented and certain heat energy sink power, a typical isotherm shape with a concave front is formed. The passage by the isotherm heat energy sink of a round form is accompanied by the formation of a local isothermal circuit. Significant variability of the shape of the isotherms is noted.
