摘要：

在自行建立的太阳能腔式吸热器热性能实验台上,研究热流密度、入口工质水体积流量、风速等参数对腔式吸热器热性能的影响.结果表明：太阳能模拟器的热流密度整体上呈高斯分布,吸热管的轴向壁温差可以高达50 ℃；正对太阳能模拟器的#5号吸热管出口水温升最高,可达40 ℃.吸热器的热损失随热流量的增大、入口流量的减小及风速的增大而增大,且热流量因素的影响最大；腔式吸热器具有较高的热效率,正向平衡计算热效率大于85%,且正、反向能量平衡的计算热效率偏差在3%以内.
Abstract:

The influence of some parameters were investigated, such as heat flux density, inlet flow and wind speed on the thermal performance of the cavity receiver on the test-bed constructed by ourselves. Results show that the heat flux density coming from the solar simulator follows Gaussian distribution on the whole. The temperature difference of receiver tube wall along the axial direction can reach to 50 ℃. The outlet water temperature rise of No. 5 receiver tube facing the solar simulator can rise to 40℃. The heat loss of the cavity receiver increases along with the increase of heat flux, the decrease of the inlet flow and the increase of wind speed, and the influence of the heat flux is the largest. The cavity receiver has high thermal efficiency, which can be above 85% through positive balance calculation. The deviation between the positive and reverse balance calculation is within 3%.
