Abstract

The performances of Peltier cooling depend first of all, on the thermoelectric properties of the thermoelectric (TE) materials and secondly on the thermal design. A survey will be given of present and future TE materials, bulk and thin film. The technologies of manufacturing the materials and of manufacturing TE modules (a rigid assembly of TE couples) will be presented with future trends. Cooling systems from milliwatts to kilowatts with temperature differentials from a few K to more than 100 K will be examined. Present day and pending applications will be reviewed. The figure of merit Z is the best overall parameter to characterize TE material, We will examine, for a standard air-air modular cooling unit, the influence of higher values of Z, on the cooling power and the coefficient of performance COP (=cooling power/electrical power). Also the influence on the cost of the system will be estimated. The COP of TE is compared to the COP of a small HFC type compressor. The aspect of development cost will be addressed as it is a major drawback to the increase of new developments.

珀尔帖冷却的当前状态

珀尔帖冷却的性能首先取决于热电材料的热电性能，其次取决于热设计。将对目前和未来的TE材料、块状材料和薄膜材料进行调查。材料制造技术和TE模块(TE偶的刚性装配)制造技术将呈现出未来的发展趋势。从毫瓦到千瓦的冷却系统，温差从几K到超过100 K将被检查。目前和待处理的申请将被审查。性能值Z是表征TE材料的最佳整体参数。对于标准的空气-空气模块化冷却装置，我们将检查较高的Z值对冷却功率和性能系数COP(=冷却功率/电力功率)的影响。此外，对系统成本的影响将进行估计。将TE的COP与小型HFC型压缩机的COP进行了比较。开发成本方面的问题将得到解决，因为这是增加新开发的主要缺点。
