Heat pipe solar collectors: A Review

Abstract

Abstract In today’s world, the consumption of energy is quickly growing, and the exhaustion of non-renewable energy sources poses a significant risk to the entire human race. The importance of renewable energy sources emerged as a result of this, and solar energy is currently considered to be among the most promising and significant sources of clean and renewable energy. There has been a significant amount of work done in the field of solar radiation harvesting in order to make the most of it. This was accomplished by substituting the standard solar collectors, which are lacking in certain elements of performance and have a lower efficiency, with a modified solar collector that is superior to the normal collectors. Among the many modifications that can be made to the solar collector, the heat pipe is particularly significant. This review will present a variety of studies on the modification of heat pipe solar collectors (HPSCs) construction and integration within the systems, as well as an analysis of the performance enhancements that were made to it. Additionally, we provide a wide range of applications that make use of solar collectors that are shaped like heat pipes. In conclusion, we offered some suggestions for potential developments in the field of heat pipe solar collectors with regard to future trends.
