Thermal characterization of fan-heat sink systems in miniature axial fan and micro blower airflow

Abstract

In portable electronics, the thermal management system must be optimized to attain the highest performance in the given space and under the given constraints. The greater the number of fins, the higher the surface area will be, thus aiding forced convection. However, by increasing the number of fins within the same available space, the performance of the fans or blowers will be degraded. The primary goal of the paper is to determine the optimization point for several different fan-heat sink combinations. The secondary goal is to find a theoretical methodology that will simulate the natural phenomena, thus obtaining the ability to optimize the system without experimentation.
