Abstract:

温差发电是一种利用热电材料中微观粒子的迁移,将温差产生的热流直接转变为电能的技术。具有体积小、无噪声、可靠性高等特点,是绿色环保的发电方式,具有广阔的应用前景。目前温差发电技术大规模应用的重要制约是发电成本,而微型热电器件的高密度集成技术将是解决这一问题的有效突破口。中国华能集团以国家千人计划专家为核心的研发队伍将以此为切入点,瞄准高效率、大功率热电器件制造技术进行攻关,开发出适用于工业余热回收和可再生能源利用的大功率温差发电装置。
Thermoelectric generation (TEG) is a technology which can directly convert heat flow into electricity with migration of micro-particles among dissimilar thermoelectric materials. TEG is a noiseless, reliable, space-saving, and eco-friendly power generation method, which has great potential in applications. Currently there is an important cost factor to address in order to break-through wide applications of TEG in marketplace. The cost can be under good control with a proposed high density integration of micro thermoelectric devices. Lead by a National 1000-Plan Expert, the research team from China Huaneng Group is making huge efforts in developing the fabrication technology of high efficiency and power density thermoelectric generators. TEG is renewable energy and is suitable for the utilization of waste heat recovery.
