摘要
本文有二部分:1.用对比实验法进一步证实了具有最小对流热损失的太阳能平板集热器的最佳间距约为6厘米。2.用集总热容实验法分项研究了蜂窝器的各项热性能,包括抑制红外辐射、抑制对流、遮拦太阳光及热容影响等。对纸、玻璃、铝箔制的几种形状和不同结构的蜂窝器做了比较实验,发现铝箔类的蜂窝器有较高的综合性能。
In this paper,the optimum air layer spacing of flat-plate solar colloctoor was experimentally studied and has got the result of about 6 cm.Besides,a new experimental technique named lumped-heat capacity-electric-heating method for measuring thermal performances of honeycomb was also described.Based on the new technique some kinds of honeycomb with different geometry and made of different materials were uu-der comparison.Experimental results shows that the performance of Alumininum foil honeycomb is better than that of glass one.It can be expected that the honeycomb made of anodized Aluminum foil shall give more better results.
