The Influence of Exciting Vibrational Force on the Performance of Evacuated Tube Heat Pipe Solar Collector

Abstract

Abstract In this research paper, it examined the effect of excitation vibration force on the thermal performance of the heat pipe evacuated tube solar collector (HPET-SC). The main target of this work is to predict the temperatures of the water when applied different values of excitation vibration force (frequency). In order to achieve these tasks, it was designed and implemented a new test rig (HPET-SC) from scratch, that containing the vibration unit to generate the excitation vibration force. We added a control board to regulate the magnitude of frequency of the excitation vibration force. The range of the vibration frequency is from 6 to 14 V. All results were compared with the reference case study (static case). All tests were done in Iraq during the winter season. It was found based on the obtained results, that the vibration has a influence on the performance of the heat pipe evacuated tube solar collector, especially when applied the vibration force with high frequency.
