3、级以上的半导体制冷空调成本比压缩制冷空调耗能要高的多。但中型功率如百瓦级的小型空调装置的耗能与压缩制冷空调的成本相差不大，且不需要制冷剂、调控方便、无噪音等优点，用于某些特殊的小型空间非常方便；而小型十瓦级的微型空调装置的耗能则远低于压缩制冷装置，在电子设备冷却、局部微环境温度控制方面，具备压缩制冷装置无法替代的优势，使中小型半导体制冷空调器进入民用领域成为可能。 本文通过使用多个多级半导体共同制冷，将冷端保护在核心，热端散布在外，并采用水冷的形式进行冷却，持续通电，使得大功率半导体制冷器的核心温度达到零下100，以求设计出性能优良的大功率半导体制冷器。本文着重进行了多级半导体模块和大功率半导
4、体制冷器的设计和研究。研究结果表明：多级半导体可以使核心温度达到更低，10个五级半导体配合使用可以将制冷器核心温度降低到零下100，实现了大功率半导体制冷器的设计。关键词：半导体，大功率，多级制冷，节能环保ABSTRACTSemiconductor technology called twenty-first Century environmental cold source, has a very large space and far-reaching significance of its development.
