Different wind speeds affect gangue thermoelectric conversion efficiency

Abstract

Abstract The wind speed of the external environment has a significant impact on the spontaneous combustion of coal Gangue Mountain, and there are different impacts on the hot spot conversion of waste heat through heat pipes and temperature difference power generation devices. To study the change rule, this paper first from the analysis of the test area environment, heat pipe cooling analysis, temperature difference power generation device for thermoelectric conversion analysis, and different wind speed cases on the thermoelectric conversion efficiency of the impact of research. Comsol software is utilized to map the changes in temperature at different wind speeds, thus affecting the thermoelectric conversion. Through the study, it is shown that the thermoelectric conversion efficiency presents a trend of change with the wind speed of the first increase and then decrease.
