摘要

A sun-tracking CPC(compound parabolic concentrator)heat pipe evacuated tube solar collector(ST-CPC-HPET-SC)with a concentration ratio of 2.3was set up

which integrated the CPC and suntracking technology into heat pipe evacuated tube collector through a simple crank-link mechanism.The heat collection performance of this ST-CPC-HPET-SC was experimentally tested under conditions of fixed

intermittent-tracking and continuous-tracking

respectively.The effect of tracking mode on heat collection time and efficiency was analyzed.Moreover

the heat efficiency was fitted and normalized

and its influencing factors were analyzed.The results showed that

the sun-tracking CPCs could improve thermal performance of the heat collector effectively

among which the simple intermittent type was preferred.Efficient working time of the ST-CPC-HPET-SC under tracking modes was 6hours

2times of that under the fixed condition.The daily average heat efficiency of the ST-CPC-HPET-SC under tracking conditions was 45%

about 16%higher than that under the fixed condition.The normalized fitting regression coefficients were both larger than 0.936

so the fitting process was reliable.Finally

the efficiency intercepts and heat loss coefficients of the ST-CPC-HPET-SC were obtained.This novel ST-CPC-HPET-SC can be applied in solar medium-temperature thermal utilization fields.
