A Review on Experimental Validation of Heat Pipe Solar Collector for Water Heating

Now a day’s climate of growing energy needs and increasing environmental concern, alternatives to the use non -renewable polluting fossil fuels have be investigated. One such alternative is solar energy; water heating prime application energy. The problem faced by existing system periodic inspections, maintenance, time component may need repair or replacement also sufficient quantity hot not available during cloudy/rainy days. Hence overcome these , heat pipe concept which utilizes low boiling temperature fluid increase efficiency, objective present work efficiency heater using fluid. Key Words: Solar heater, pipe, (working fluid), thermosiphon.
