LOW-COST SOLAR WATER HEATER TO FUNCTION DURING SUN-OFF PERIOD USING PHASE CHANGE MATERIAL

The present invention discloses relates to low-cost solar water heater to function during sun-off period using phase change material. The objective of the present invention to provide overcomes the inadequacies of the prior art in using of phase change material in solar heater. The solar water heater capable to function during sun-off Period, the solar water heater comprises a flat plate collector assembly, a heat exchanger plate and a connecting assembly. The Flat plate collector Assembly comprises a heat exchanger plate, a heat collecting metal plate, a tubular heat exchanger, a plurality of metal pipe and an insulation iron box. The plurality of Metal pipe is used to cover the tubular heat exchanger & filled with a Phase changing material. The phase changing material is used to store latent heat during sunshine and release after sun off period.
