基于STC89C52的制冷片热效应控制系统研究

Research on thermal effect control system of refrigerator based on STC89C52

半导体制冷片是根据帕尔贴效应的原理设计制成,半导体制冷片由于能量转化单一,因此可以连续地,长时间地工作。而其本身产生热的同时也能产生冷,因而不需要制冷剂,同时半导体制冷片没有污染源,具有安装简易,绿色环保的优点。半导体制冷片能将电流转换为能量,通过改变输入的电流大小实现温度高低调节。其中,通过额外安装的散热片可以对半导体制冷片的导热端进行散热,很好地使制冷片的热惯性达到理想要求。

The semiconductor refrigerating sheet is made into a semiconductor refrigerating sheet according to the principle of the Peltier effect. Since the semiconductor refrigerating sheet has a single energy conversion,it can work continuously and for a long time. While it generates heat itself,it can also generate cold,so no refrigerant is needed,and the semiconductor refrigerating sheet has no pollution source,and has the advantages of simple installation and environmental protection. The semiconductor refrigerating chip converts the current into energy,and adjusts the temperature by changing the magnitude of the input current. Among them,the heat-dissipating end of the semiconductor refrigerating sheet can be dissipated by the additionally installed fins,so that the thermal inertia of the refrigerating sheet can be ideally achieved.
