In the solar chimney solar collector plates are used for heating up the ambient air. Increase in the temperature of the air inside the chimney increases the efficiency. Thus the solar absorber selected plays an important role in the efficiency of the solar chimney. In this paper the heat transfer analysis is done for solar absorbers like aluminium, copper and copper chromium alloy using ANSYS.The fluid dynamics analysis helps us to select the optimum sollr absorber. the analysis of various solar collector plates ,the nodal temperature of the copper chromium plate is compared with the copper and aluminium plates. The heat transfer and thermal conductivity of the copper chromium plate is compared with copper and aluminium plates
