Abstract:A general model of cylindrical structure filled with linear metal cellular material is constructed to simulate a multi-tubular heat exchanger in this paper. Optimum design of cellular material distribution aims at maximization of heat dissipation rate while minimizing the prescribed flow pressure. Three-dimensional variation of temperature is considered. Five types of inner cell topology and various fluid nominal velocities are compared. We discuss in general the guideline for multitubular heat exchanger design to maximize heat dissipation efficiency based on insights from these optimization results. In the final part, a CPU cooler design is studied by our presented approach. © 2006 Springer.
