A Review on Experimental Analysis of Solar Water Heater Using Pulsating Heat Pipe

Solar energy is a very large, inexhaustible source of energy with two main distinct advantages as follows; the first one is unlike fossil fuels and nuclear power, it is an environmentally clean source of energy and secondly it is free and available in lump in almost all the parts of world. Solar energy, on other hand shows promise of becoming a dependable energy source without a new requirement of highly technical and specialized nature for its wide spread utilization. This solar energy are used for solar water heater in domestic and industrial purpose. Pulsating heat pipe is a fast responding, flexible and high performance thermal conducting device. Our intention behind writing this review paper is that the use of pulsating heat pipe in solar water heater to improvement the efficiency of solar absorbing collector plate. Review of previous work based on experimental and theoretical studies have established the advantages of pulsating heat pipe in solar water heater.
