This book was released on 2020-12-22 with total page 429 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about theories and applications of thermosyphons and heat pipes. It discusses the physical phenomena that drive the working principles of thermosyphons, heat pipes and related technologies. Many applications are discussed in this book, including: rationalizing energy use in industry, solar heating of houses, decrease of water consumption in cooling towers, improvement of the thermal performance of industrial and domestic ovens and driers and new devices for heating stored oil and gas in petrochemical plants. Besides, the book also presents heat pipe and thermosyphon technologies for the thermal management of electronic devices, from portable equipment to airplanes and satellites. The first part of the book explores the physical working principles of thermosyphons and heat pipes, by explaining current heat transfer and thermal resistance models. The author discusses the new heat pipe and thermosyphon technologies that have been developed in the last decade for solving a myriad of electronic, environment and industrial heat and thermal problems. The focus then shifts to the thermosyphon technology applications, and the models and simulations necessary for each application – including vehicles, domestic appliances, water conservation technologies and the thermal control of houses and other structures. Finally, the book looks at the new technologies for heat pipes (mini/micro) and similar devices (loop heat pipes), including new models for prediction of the thermal performance of porous media. This book inspires engineers to adopt innovative approaches to heat transfer problems in equipment and components by applying thermosyphon and heat pipe technologies. It is also of interest to researchers and academics working in the heat transfer field, and to students who wish to learn more about heat transfer devices.

Download or read book Experimental Comparison of Heat Pipes and Thermosyphons Containing Methanol and Acteone written by Jana Strain and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The cold chain industry has a need for a standalone, electricity independent cooling unit that is used for both storage of warehouse product and on deliveries [1]. Mixed temperature fresh and frozen food deliveries are problematic without the distributor having specialized duel compartment refrigerated trucks [2]. These trucks permanently reduce the available capacity for payload delivery [2]. It would be valuable to the cold chain industry to have a passive, independent, storage unit that can be moved using a forklift and placed anywhere within a reefer or warehouse [1]. This versatile unit is a simple mechanical system, but presents a complicated thermal problem. One of the design challenges is to thermally isolate the load from the environment and to maintain thermal conditions for a specified length of time. A proposed storage system uses heat pipes to connect the cargo compartment to a heat sink containing solid CO2. Heat pipes are a simple, passive, and quiet way to transfer heat. Heat pipe design and theory is an active area of research with numerous papers in the literature; however, there is less reported about the actual process of manufacturing. This thesis investigates a new potential application of heat pipes, with a focus on the manufacturing process and experimental performance. A total of four heat pipes and two thermosyphons are created using acetone and methanol as the working fluids, and copper and aluminum as the heat pipe housing. Performance is compared to an insulated copper tube with the same outer dimensions, where the primary performance metric is steady-state thermal resistance. In addition, transient performance is quantified as well as the temperature distribution along the outer in the evaporator, adiabatic and condenser regions.Results show that the prototypes made out of copper reached steady-state faster than the aluminum pipes, while also having a smaller temperature differential between the evaporator and condenser. Methanol and acetone have similar performance over the temperature ranges of 198 K to 358 K. The best performing prototype is a copper thermosyphon containing methanol which achieves an effective thermal resistance of 2.0 K/W with an applied load of 40.7 W, when the condenser is cooled with dry ice in acetone. When cooled with ice water the copper thermosyphon achieves an effective thermal resistance of 0.5 K/W with a load of 40.7 W.

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"--

Download or read book Heat Pipe and Thermosyphon for Thermal Management of Thermoelectric Cooling written by Thiago Antonini Alves and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The heat pipe and thermosyphon are passive heat transfer devices with phase change, which can be applied for thermal management of thermoelectric cooling, such as the TEC hot side. The heat pipes basically consist of a metal tube sealed with capillary structure internally that is embedded with a working fluid. This capillary structure can be made of screen meshes, grooves, or sintered media. The thermosyphon is a heat pipe assisted by gravity, because it has no capillary structure. Then, in this chapter, manufacturing of low cost and easy-to-manufacture heat pipes and thermosyphon is described in detail, and an experimental evaluation of their thermal performance is accomplished. The considered devices were a rod, a thermosyphon, a mesh heat pipe, a grooved heat pipe, and a sintered heat pipe. According to the behavior of the global thermal resistance and the effective thermal conductivity, the passive devices operated satisfactorily with the exception of the rod and the thermosyphon in the horizontal position. The heat pipes were the best among the tested devices and the best position was vertical.
