【摘要】 现代化经济进入迅速发展的时期,人类生产和生活对能源的需求也越来越大,目前世界最主要的能源形式是电能,电能的主要来源是化石燃料能源转化而来,然而,由于化石能源的有限性和化石能源在使用的过程中产生的二氧化碳和硫的氧化物造成的温室效应和酸雨对坏境的破坏。全世界对新的能源的开发和利用越来越重视,特别是清洁、环境友好型能源备受关注。太阳能是太阳以电磁波的形式辐射到地球上的一种能源,太阳能作为一种储量丰富、绿色环保的能源,通过各种转化方式可以将其转换为电能,从而缓解化石能源面临的枯竭的状况,也可以解决温室效应和酸雨腐蚀等全球性难题。温差发电是一种直接将热能转化成电能的技术。通过温差发电技术和太阳热能的完美结合,可以将太阳辐射转化为电能;而随着材料技术的进步,半导体温差材料性能的提高,太阳能温差发电转换效率的提高,太阳能温差发电技术和太阳能温差发电器越来越受到关注。本论文的主要内容如下:1.介绍热电材料的发展、热电材料在温差发电领域的应用与发展现状;和太阳能的介绍及其太阳能温差发电的应用。2.介绍热电的基本理论,分析了提高热电材料电优值的方法和温差发电器的功率输出;及其ANSYS热分析软件的基本原理。3.应用ANSYS仿真软件对太阳能温差发电器模块两端温度最大化模型的优化仿真。4.温差发电器的实验装置组成及其实验研究;通过几组对比实验的来验证仿真优化模型的可行性与高效性。5.最后,对全文的总结分析,并对太阳能温差发电的看法与展望。更多还原

【Abstract】 Modern economy enters the fast developing period of human life and production, demand for energy is growing, is currently the world’s most main form of energy is electrical energy, power is the main source of fossil fuel energy conversion and come, however, due to the limitation of fossil energy and the carbon dioxide and sulfur acid produced in the use of fossil fuels, caused the greenhouse effect and the destruction of bad border . To development and utilization new energy are growing importance in worldwide, particularly clean, environmentally friendly energy.Solar energy is the energy of electromagnetic radiation to the earth from sun, solar energy as the one kind of abundant reserves and green environmental protection, the energy can convert to electricity through various conversion ways and relieve the dry condition of fossil energy, also solve the global problems such as greenhouse effect and the corrosion of acid rain.Thermoelectric power is a technology of transit heat energy into electricity directly. Through the perfect combination of thermoelectric power technology and solar thermal energy, solar radiation energy can be converted into electricity; And as progress of material technology, improving semiconductor thermoelectric materials and the performance of thermoelectric power conversion efficiency of solar, solar thermoelectric power technical and solar thermoelectric generator are paid more and more attention by people.The main content of this paper is as follows:1. Introduce the development of thermoelectric materials, thermoelectric materials in the application and development; Solar energy introduction and the application of solar electricity.2. Introduction the basic theory of thermoelectric, analyses the way to improve thermoelectric materials’electricity optimal value and the output power of the thermoelectric generator; And introduce the basic principle of thermal analysis software-ANSYS.3. Simulat the maximization temperature between two ends of solar generator module by use simulation software-ANSYS. 4. Study the component of thermoelectric generator device and do some experiments; Test simulation model feasibility and efficiency through several groups of experiments.5. Finally, summarize this article and analyze the the prospect and view of solar thermoelectric power.更多还原
