Transient Heat Transfer Analytical Model for Low-melting-point-metal Phase Change Material Heat Sink

Abstract

This paper presents a low-melting-point-metal phase change material/air natural convective cooling combined heat sink for the thermal control requirement with transient thermal shock. A theoretical transient heat transfer analytical model is established, and the general process for the design of the heat sink is proposed. The thermal control performance and advantages of this heat sink were demonstrated through numerical simulation studies of specific cases, and the reliability of the analytical model was verified by comparison with the numerical results. The transient heat transfer analytical model established in this paper can provide rapid performance prediction and evaluation for the low-melting-point-metal phase change material/air natural convective cooling heat sink, and provide guidance for practical thermal design.
