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 multi-tubular 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.
