The dynamics of phase changes in a heat storage of thermal control system for onboard radio-electronic equipment

Abstract

The paper considers a heat storage (HS) based on the materials with a “solid-liquid” phase change for a thermal control system for on-board radio electronic equipment (REE) with periodic and short time action. To intensify the heat transfer in the HS design, ribs made of hyper heat-conducting plates are used. The dynamics of temperature fields and phase transformations in the HS volume is studied on the basis of numerical modeling. The results of calculations have shown that the use of ribs in the form of hyper heat-conducting plates allows significantly reducing the amplitude of temperature fluctuations at the seat of the REE unit.
