| Abstract: | In this paper the natural convective heat transfer in a rectangle cavity was discussed and the cavity has five discrete heat sources on the vertical wall. The numerical solution was given. The effects of the Rayleigh numbers and aspect ratio were analyzed. This analysis useful in treating the heat dissipation of electronic devices. |
