半导体制冷和泵热循环机理的研究

在半导体制冷和泵热循环中，紧紧抓住能量的载体－－电子这一关键环节建立热力学系统。根据非平衡态统计力学的结果，详细讨论了汤姆逊热与焦耳热和傅里叶热的关系，提出汤姆逊热就是焦耳热和载流子在有温度梯度的均匀半导体内运动时输运的热运动能量之和。论证了组成半导体制冷和泵热循环的基本物理过程是Ｐｅｌｔｉｅｒ效应和Ｔｈｏｍｓｏｎ效应及电源所提供的非静电力对电子的作功过程。而焦耳热和格波所引起的傅里叶热不是电子循

Study of the Physical Mechanism of Thermoelectric Refrigerator and Heat Pump of Semiconductor

For the thermoelectric refrigerator and heat pump of semicoductor, this paper discusses the relations between Thomson heat, Joule heat and Fourier heat. It proves that the basic physical processes of thermoelectric refrigerator and heat pump of semicoductor are Peltier effect, Thomson effect and working process by electric source. But Joule heat and Fourier heat are not basic physic processes of it.
