太阳能集热器强化传热特性研究

Research on Enhancing Heat Transfer Characteristics of Solar Energy Collector

在自然对流的情况下,在理论分析的基础上,对太阳能集热器的典型结构进行优化。在对吸热板进行改良后,采用对比试验的方法,研究太阳能集热器的强化传热特性。分析热性能效率曲线可知:吸热板添加筛网和墨绿色涂层的集热器集热效果较优,可达到强化传热的目的。

The article is to optimize typical structure of solar energy collector on the basis of theoretical analysis and under the condition of natural convection flow. After the improvement of absorber plate, it took contrast tests to study heat transfer characteristics of solar energy collector. By analyzing thermal performance efficiency curve, we can know that the heat collecting effect of solar energy collector whose absorber plate added screen mesh and blackish green coating is optimal, it can achieve the purpose of strengthening heat transfer.
