“…And mostly the benefit of phase change, namely the latent heat of evaporation and high heat flux densities were attractive to the designers of heat transfer equipment. [1] The objective of this project is to fabricate and construct heat pipe solar collector with an absorber plate and to evaluate its efficiency via a distinct as well as unprecedented working method.…”

Solar collectors have always been radical tools in the theoretical field of mechanical engineering as well as for any relevant establishment. Owing to uplifting demand for renewable energy sources, the investment for solar collector use is augmenting. Apart from flat plate or regular types, hybrid heat pipe solar collector could be taken for a neoteric type of solar collector. This research work aimed at designing and setting up a hybrid heat pipe solar collector and to evaluate the efficiency. A hollow copper pipe was used as heat pipe whose bottom end was closed by brazing a tiny solid copper block. Later the copper pipe was filled with acetone as the working fluid of heat pipe and by a burner, the bottom end of the pipe was heating until the pipe was filled with the vapor of acetone and then top of the pipe was closed by soldering. All other heat pipes, made of the same approach, were assembled then to an absorber plate touching the heat pipes forming the entire layout of heat pipe solar collector. The structure was then examined in the month of November and December and provided peak efficiency of about 27.44%. The efficiency could be properly enhanced by further research and examination of the methodology of fabricating the heat pipes.
