Summary The present work investigates an active waste heat recovery system for the side walls of the aluminium electrolysis cells, enabling utilization of the extracted heat in power generation. This will potentially lead to energy efficiency improvement in the primary aluminium production industry and an enhanced aluminium production rate. An experimentally validated loop thermosyphon heat pipe model was used for heat extraction from the cell side wall. Boosting system thermal efficiency through waste heat recovery, by means of a heat utilization system, and increasing the level of control, as well as thermal equilibrium, stand as the main addressed objectives of the current study, which consequently result in an increased aluminium production rate. An organic Rankine cycle is incorporated into the system, and its performance is evaluated, taking into consideration the operating situations in terms of available temperature and thermal power range.

“…[6] Consequently, there is a growing interest in passive, quiet, and compact solutions for thermal management of electronics.Heat pipes (HPs) are superior two-phase heat transfer devices widely used in many cooling applications. [7] They are completely passive devices, meaning they do not require an additional power source for operation. HPs offer numerous benefits, including low cost, excellent thermal conductivity, consistent performance, and minimal efficiency degradation even over extended time periods of exploitation.…”

This paper presents an experimental study of heat pipes supported by phase change materials (PCMs) coated at their adiabatic sections in application for electronics cooling. The PCMs investigated in this research were palmitic acid and beeswax, the latter being considered as a more cost‐effective alternative. The study focused on three powers: 20W, 25W, and 30W. The experimental results revealed that the incorporation of palmitic acid as a PCM led to a reduction in component’s maximum temperature by 13.3%, 12.6%, and 11.8% for the respective powers. Utilization of beeswax resulted in temperature reductions of 5%, 5.2%, and 8.4%. Notably, for higher heat flux conditions, the influence of beeswax on temperature control was comparable to that of palmitic acid. Furthermore, beeswax demonstrated a significantly higher capability to mitigate temperature decrease during cooldown, serving as a superior measure against overcooling. Moreover, during the thermal cycling scenario considered in this study, beeswax reduced the peak‐valley temperature by 25%, while palmitic acid achieved a reduction of 14.6%. These findings suggest that beeswax has the potential to serve as an alternative to traditional organic PCMs in electronics cooling applications that utilize heat pipes.This article is protected by copyright.
