Download or read book Heat Pipes written by Yuwen Zhang and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heat pipes are efficient passive devices that can transfer large amounts of heat over long distances with small temperature differences between the heat sources and sinks by evaporation and condensation of the working fluid. Heat can be transferred without the use of any mechanically moving parts such as pumps and active controls in heat pipes. The vapor and liquid circulate in the conventional heat pipes, including thermosiphons, via evaporation/condensation and capillary or gravitational forces. For pulsating heat pipes, liquid slug and vapor plugs in the capillary tube oscillate due to evaporation and condensation. The effective thermal conductivity of a heat pipe can be three orders of magnitude higher than that of a copper rod with the same size. A heat pipe can find its applications in many sectors of industries, including electronics cooling, energy systems, spacecraft thermal control, permafrost cooling, and manufacturing. This book presents current research and development related to the design, applications and technology of various heat pipes, including conventional heat pipes and thermosyphon, pulsating heat pipes, loop heat pipes, and variable conductance heat pipes. Design tools based on computational fluid dynamics simulation and HSHPTM (Heat Sink-Heat Pipe Thermal Module) software are also presented.

Available in PDF, EPUB and Kindle. Book excerpt: "Preface This book covers the state of the art of adsorption research and technologies for relevant applications based on the use of the efficient heat transfer devices--heat pipes and two-phase thermosyphons--with the objectives of energy efficiency and sustainability. The severities of energy crisis and environmental problems have been calling for rapid developments in Freon-free air conditioning and heat pump technologies, the heat exchangers, which are considered as the components of prime importance. The concerns of energy consumption and environmental pollution urge researchers to work on the development of clean energy and the utilization of waste energy. From this viewpoint, interest in fuel cells and thermally activated (heat pipe heat exchangers) adsorption systems using natural refrigerants and/or alternative to hydrofluorocarbon-based refrigerants has increased significantly. The quest to accomplish a safe and comfortable environment has always been one of the main preoccupations of the sustainability of human life. Accordingly, during the past few decades, research aimed at the development of thermally powered adsorption cooling technologies has intensified. They offer two main benefits: (1) reduction in energy consumption and (2) adoption of environmentally benign adsorbent/refrigerant pairs, without compromising the desired level of comfort conditions. The efficiency of new power sources (co-generation, tri-generation systems, fuel cells, photovoltaic systems) can be increased with the help of heat pipe heat exchangers, solid sorption heat pumps, refrigerators, accumulators of heat and cold, heat transformers, and fuel gas (natural gas and hydrogen) storage systems. Low-temperature power systems are generally significantly less expensive to build"--
