Upon the structure of convective heat exchangers and their surroundings,a conjugate solution with different dimension for heat transfer and flow is proposed. Application of this method on a sodium pool of a fast breeder nuclear reactor and its surrounding architeture is presented. Numerical solution has verified the correctness and efficiency of this method.
