摘　　要：本文建立了平板式冰蓄冷器内融冰放冷过程动态模型 ,应用边界层理论 ,并考虑自然对流现象 ,求得了数值解 ,数值解与文献实验值吻合得较好 。A more precise dynamic model of characteristic of ice-melting inside horizontal rectangular isothermally-heated capsules has been devoloped. Employing boundary-layer theory and thermal conduction and free convection theory, we obtained the precise results of the heat flux from below or above and the total melting time depending upon he temperature of wall. The results show good agreement with experimental data of references. Also fitting formulas convenient to engineering calculation are given.
