Hybrid Powder Metallurgical Production Of Heat Sinks Based On The Locally Dominant Heat Transport Mechanism

Copper-based heat sinks are essential components in the cooling of electronic assemblies. In most cases, the aim is to increase the heat-transferring surface area in order to achieve a more efficient heat dissipation by applying Newton's law of cooling and using free and forced convection. However, this overlooks the f...

Numerical Optimization of a Developed Multi-Baffle Heat Sink for Modern Electronic Devices

Optimal thermal control is crucial for ensuring the efficiency and stability of modern electronic devices. This paper analyzes four multi-barrier heat sink models using computational fluid dynamics (CFD) to optimize heat removal from a hot surface under constant convection. We analyzed the models under laminar flow con...

Influence of Thermal Boundary Conditions on Heat Transfer in Turbulent Annular Pipes

Turbulent concentric annular pipe flow with heat transfer is investigated using the stochastic one‐dimensional turbulence (ODT) model. In the present study, annular pipe flow is investigated at fixed bulk Reynolds number and Prandtl number using two different thermal boundary conditions: uniform heat flux (UHF) and c...

A Comparative Study on the Thermal Performance of Copper and Stainless-Steel Heat Pipes

Heat pipes are highly efficient passive thermal devices that exploit phase-change mechanisms —evaporation and condensation of a working fluid—to transport heat with minimal temperature drop. This study presents an experimental and computational investigation of a 204 mm copper–water heat pipe equipped with a stainless-...
