Abstract

In order to improve the efficiency of solar energy utilization in buildings, a solar pulsating heat pipe collector based on Fresnel concentrator is proposed, and the operation performance of the device is experimentally tested by using carbon nanotube-doped metal nanofluid as the heat transfer medium. Comparative studies show that the doped metal nanofluids exhibit better light-absorbing properties, and the higher the concentration, the better the light-absorbing properties. During the test period, the maximum temperature in the evaporation section of the collector was 119.5 ℃, and the average photothermal conversion rate of the device was the highest （69.4%） when the concentration was 0.015‰, which was 48.5% higher than that of hydrofluoroether. Appropriately reducing the liquid filling ratio of pulsating heat pipes is conducive to the improvement of solar energy conversion efficiency.
