对流给热系数测定实验装置的改进

Improvement of Experimental Equipment for Determination of Convective Heat Transfer Coefficient

在传热实验中,由于实验装置结构、测量方法、操作过程等不同,实验结果与理论值会产生偏差。为了让学生在掌握传热理论基础上,熟悉装置结构和操作过程,便于操作和数据采集,并树立节能意识,我们对实验装置进行改进,增强了学生的动手操作技能和计算机应用能力,达到了提高综合素质的目的。

Deviations between experimental results and theoretically calculated values always occur in heat transfer experiments due to the differences in equipment configurations, determination methods and oper- ation procedures. The heat transfer unit in our laboratory has therefore been improved. The aim for students is to understand the unit configuration and its operation process beneficial to their operation and data collection on the basis of their learning of the heat transfer principle, and to strengthen their con- sciousness for energy save and enhance their both experimental and computer operation skills and finally to promote their comprehensive quality.
