To strengthen the convective heat transfer ability of the limited cooling air in the cabin, temperature field homogenization (TFH) in the core flow region of the engine block area was achieved. The TFH optimization model helped minimize the temperature gradient in the core flow region and maximize it at the heat transfer boundary, and the optimum vector field and flow path were obtained. More comprehensive changes to the structural design were made according to the TFH.

This paper examines a code-to-code verification between two thermal models. One used a non-commercial code; the other a commercial. A point heat source was applied to one end of a cylindrical geometry. Melting and re-solidfying of a 316 L stainless steel alloy was considered. Temperature dependent material properties and latent heat were included. Mesh independency was achieved. Positive agreement of thermal histories, temperature profiles, melt pool depth and maximum temperature along the rod.

This paper presents a numerical investigation in which thermal performance characteristics of pin fin heat sinks enhanced with phase-change materials (PCM) designed for electronic devices cooling are studied. The main purpose of this article is to investigate different effective parameters on the heat sink base temperature and melt fraction. The studied geometric parameters are the number, thickness and height of fins.
