power transistors dissipating

An array of power transistors dissipating a total of 25 W is to be cooled by mounting them on a 50-mm by 50-mm square aluminum plate. It can be assumed that the back side of the plate is insulated. While air surrounding the package is at 270C, the surface of the plate is not to exceed 770C for normal operation. You are to explore various mechanisms and design feasible solutions to satisfy this temperature requirement. Perform a quick calculation to justify disregarding the radiation. You may consider free versus forced convection, changing surface orientation and adding one or more fins. Discuss various design options considered and justify your final selection(s). Consider criteria such as cost, manufacturability, safety, reliability etc. at least qualitatively. Rank the feasible solutions in your conclusion of the report.
