Paper Abstract

Precision flow pumps have been widely studied over the last three decades. They have been applied as essential components in thermal management solutions for cooling electronic devices offering better performance with low noise and low power consumption. In this work, a novel configuration of a miniature piezoelectrically actuated flow pump with the purpose of cooling a LED set inside a head light system for medical applications has been studied and it will be presented. The complete cycle of pump development was conducted. In the design step, the ANSYS finite element analysis software has been applied to simulate and study the fluid-structure interaction inside the pump, as well as the bimorph piezoelectric actuator behavior. In addition, an optimization process was carried out through Altair Hyperstudy software to find a set of parameter values that maximizes the pump performance measured in terms of flow rate. The prototype manufacturing was guided based on computational simulations. Flow characterization experimental tests were conducted, generating data that allows us to analyze the influence of frequency and amplitude parameters in the pump performance. Comparisons between numerical and experimental results were also made.
