Experimental analysis of thermal performance of solar collectors with different numbers of heat pipes versus a flow-through solar collector

This paper presents a comparative study of the experimental analysis of two heat pipe solar collectors with different numbers of heat pipes and a flow-through collector. For this purpose, three collectors were designed, constructed and tested side-by-side under various environmental conditions. In this study the three collectors selected were: first, a collector with six heat pipes, type(I); second, a collector with twelve heat pipes, Type (II);...
