摘要：面对全世界日益紧张的自然资源和环境问题，有效地利用太阳能资源成为了我们可持续发展的有力手段之一，而在目前新型的制冷领域上，半导体制冷技术作为一种利用热电材料进行制冷的新技术有着传统制冷方式不可比拟的优势，在当前能源紧张、电力短缺的情况下，将太阳能发电与半导体制冷技术有机地结合，发展太阳能半导体制冷技术有着重要的现实意义。本课题就是在这样的背景之下，将太阳能与半导体制冷结合起来，设计开发一台半导体制冷箱，可以在天气炎热的时候，为少量药品或者食品等需要低温储存的物体暂时冷藏。本文根据论文题目对半导体制冷箱进行设计，主要由三个系统组成，供电系统、半导体制冷系统、控制系统。另外在设计时，储能蓄电池的功率满足要求，无论阳光是否充足，制冷器一天24小时均能正常工作。22899

Design of Semiconductor Refrigerator
Abstract：Being confronted with the decreasingly natural resources and the environmental problems, making efficient use of solar energy resources has become one of the powerful means of sustainable development. But in the current new refrigeration field, semiconductor refrigeration technology, as a kind of new technique that uses thermoelectric materials to get cooling, has an incomparable superiority to traditional refrigeration way, in the current energy shortage, power shortage situation, combining the solar power generation and semiconductor refrigeration technology, developing solar semiconductor refrigeration technology has important practical significance. This topic is based on this background, combines the solar energy and semiconductor refrigeration, designs a portable solar power semiconductor refrigerating cabinet, in hot weather, it can be needed for a small amount of medicine or food to frozen at low temperature. This paper is conducted to design a semiconductor refrigeration box based on the thesis topic, mainly consists of three systems: Power supply system,   Semiconductor refrigeration system, Control system. Besides, the power storage batteries should meet the requirements, regardless of whether there is plenty of sunshine, the refrigerator can work 24 hours daily.
