Prediction Model of the Direct Solar Vacuum Tube

Article Preview

Abstract:

Based on the heat transfer, the prediction model of the direct solar vacuum tube was studied, the concept of local heat loss coefficient was put forward, through the temperature distribution model of metal pipe and fin, the calculation method of average heat loss coefficient was obtained, the calculation accuracy of performance was improved. The results were compared with dates of Abdul Waheed Badar et al, error is less than 7.15%, the calculation accuracy of model meets the requirements. The impact of various factors on the performance of the collector tube was studied.
