Natural convection heat transfer from rectangular V-fins had been investigated numerically with different heat flux values (175, 350, 525, 700 and 875 Watt per square meter). Fin thickness (5) mm, fin high (18) mm, space between fin and other (10) mm, the heat sink base plate was heated by an attached maximum electric heater 2225 W/m2 with an identical size as the base plate. The mathematical model of the base plate and fins are solved numerically using an COMSOL (5.0) after describing the mesh model using the COMSOL (5.0) and assume the properties of air variation with film temperature. After find the numerical results make validation between numerical and the experimental results, where found good agreement between them. Empirical correlations for the overall Nusselt number versus average Rayleigh numbers for these configurations are obtained and compared to other correlations cited in the literature. The range of Rayleigh numbers, Nusselt number and base plate temperature, 1.7*107 to 12*107, (37°C to 83°C) and (25.6°C to 81.34°C).
