Abstract
This paper describes cooling performance of miniature cooling fans and blowers. In recent years, several types of miniature devices that can generate cooling airflow into electronic equipment have been developed. These devices are enough thin and small and these are usable in high-density packaging electronic equipment such as laptop computers and portable devices. In this study, we are trying to evaluate an optimum selection of these devices in order to obtain higher cooling performance in high-density packaging electronic equipment by using these devices. In this report, we compared effectiveness of three types of the miniature fans and the piezoelectric micro blower mounted in the narrow flow passage from the viewpoint of cooling performance through heat transfer experiment.
