Solar water heater , embossed platesAbstract
The sun is the source of all energies available on the earth. The major advantage of the solar
energy when compared to other alternative energies is that it is available in ample amount throughout the
year and the best application of it is for heating and energy generation purpose. The objective of present
work is to develop such solar water heater in which the absorber plate with various embossed shapes which
are likely circular, triangular and rectangular( square). Also in addition to this the cavity, that is developed
will be filled with various heat absorbing materials like Sand ,Salt and powdered form of glass. The thermal
performance of this solar water heater will be evaluated with the help of “K” type thermocouple with
appropriate location. The effect of various embossing shape on the performance of solar water with and
without using black-sand to enhance the performance of solar water heater.
