Overview of heat pipe and applications in renewable energy based systems

Abstract

The heat pipe is among thermal physics' greatest accomplishments and the thermal transmission technology of this century owing to its different capacity for transporting heat from broad distance eliminating any loss. The core uses of heat pipes tackle environmental problems, energy management and fuel performance. High heat flux applications plus the circumstances in which non-uniform heat charge combination, reduced airflow through the components that generate heat and weight or space constraints have been created, as an efficient and proven thermal solution. This segment discusses technology for heat pipe briefly and illustrates its simple applications as passive thermal control system. Heat pipes have a passive function and high performance for certain applications with a two-stage efficient heat transfer device. Energy saving schemes is introduced by way of wickless assisted with wickless heat pipes or capillary pumped loop for agricultural cold storage, data center cooling, bakery waste heat collection and vehicle dashboard cooling. Thermosyphons are used to collect accumulated heat (solar pool, geothermal water), to dissipate excess heat to the atmosphere and to retain surplus heat in materials of phase transition. The method built for green energy is focused on electricity storage. In such uses, heat pipes have an inexpensive alternative to zero greenhouse gas emissions.
