本文对一种新型波纹表面冷却顶板进行了实验研究。将新型板的热通量和传热系数与平面板的参考值进行了比较。结果表明，新型平板冷却性能的提高是由于平板面积的增加和自然对流换热的增强。在典型工况下，新型板的冷却能力比参考板提高了26%~ 55%。此外，新型面板更能抵抗露点的风险，并通过与之配合的热泵实现更高的EER值。
In this paper a new type of cooling ceiling panel with corrugated surface has been studied experimentally. A heat flux and a heat transfer coefficient for the new type panel were compared with the reference values obtained for a panel of a flat surface. It was shown that increase of the new panel cooling performance results both from increase of its area and from enhancement of natural convection heat transfer. For typical operation conditions, the increase of the new type panel cooling capacity varies from 26 to 55%, in comparison with the reference panel. In addition, the new type panel is more resistant to the risk of dew point and enables the achievement of higher EER values by the heat pump cooperating with it.
