| Abstract: | The thermal performance of the conical cavity-type receiver for solar energy collecting system are investigated by experimental data and numerical models.The proportion of diversified heat losses and the entire thermal efficiency in different temperatures are calculated based on the numerical models.The relationship between the heat power and the cavity receiver's efficiency is obtained by the experimental data.The experimental results show that the thermal performance of the conical cavity-type receiver is considerably steady and the thermal efficiency is up to 85%. |

| Keywords: | solar energy thermal performance cavity receiver thermal efficiency |
