APPLICATIONS OF HEAT PIPES IN ENERGY CONSERVATION AND RENEWABLE ENERGY BASED SYSTEMS

In this paper, design and characteristics of different energy conservation and renewable energy based system using heat pipes as thermal control element have been discussed. Heat pipes provide two-phase reliable heat transfer system with passive operation and high effectiveness for these applications. Energy conservation system for data center cooling, agricultural products cold storage, bakery waste heat recovery and automotive dashboard cooling was achieved by using gravity assisted wickless heat pipes (or thermosyphons) and capillary pumped loop. Renewable energy based electricity generation system developed in this study utilizes thermosyphons to extract stored heat (solar pond, geothermal), to dissipate waste heat to ambient and to store waste heat into phase change materials. Heat pipe provide economical and zero greenhouse gas emission solution for these applications.
