Solar Collector Plate Collector plate 1 m wide, W=1 m Water tubes x insulation Radiation heat transfer in T Question: what will be the temperature distribution of the plate, T(x), if there is a constant radiation heat flux q” coming in. For simplicity, assume the temperature immediately below the water tube is constant, T(x=L)=T O . x=L=0.1(m) Water flow

Temperature Distribution Model the solar heat flux as continuous generation inside the plate: averge solar flux around noon time: q"= 700 W / m Assume it uniformly distributes inside the plate with thickness = 1 mm q = q / = 700000 W / m separation between tubes 2L = 2 cm, L = 10 cm Heat diffusion equation: T + q k = 0, k = 240 W / m K for Aluminum with boundary conditions: dT dx (x = 0) = 0, T(x = L) = T integrate twice to get T(x) = - q 2k Apply boundary conditions: A = 0, B = 40 + q 2k 2 3 2 O , , , ( ) ( ) δ ′′ = ° = - + + = + - = + 40 40 2 40 2 2 2 2 2 2 C d T dx q k x Ax B L T x q k L x 1458 3 0 01 2 .
