Thermal management in optical and electronic devices

摘要

A thermal management system for electronic devices is provided. The thermal management system includes a plurality of synthetic jets provided in a stacked arrangement and separated by respective spacers within the stacked arrangement. The stack of synthetic jets may be used to facilitate airflow in the thermal management system, such as to facilitate air flow over a heat sink in one implementation.

主权项

1. An electronic device, comprising:
one or more heat generating electrical components; and a thermal management system, comprising:
a heat sink in thermal communication with the one or more heat generating electrical components;a stack assembly comprising:
a plurality of synthetic jet diaphragms; anda plurality of spacers, wherein each pair of synthetic jet diaphragms is separated by a respective spacer of the plurality of spacers to form a respective synthetic jet and wherein each spacer comprises an opening through which air is expelled during operation of the synthetic jet diaphragms,wherein a plurality of synthetic jets are defined by the plurality of synthetic jet diaphragms and the plurality of spacers such that each synthetic jet comprises a respective upper diaphragm and a respective lower diaphragm separated by a respective spacer and wherein each synthetic jet shares at least one diaphragm with an adjacent diaphragm.
