1. A system, comprising:
a cooling cell including a cooling element configured to undergo vibrational motion to draw air into an entrance of the cooling cell and provide a stream of hot air from the cooling cell, the stream of hot air being heated by a heat from a heat-generating structure, the stream of hot air having a first temperature after exiting the cooling cell; and
an egress passageway through which the stream of hot air passes toward an egress, the stream of hot air developing a first pressure in the egress passageway such that cool air is drawn into the egress passageway through at least one inlet, the cool air mixing with the hot air such that a mixture of the hot air and the cool air outside the egress has a second temperature less than the first temperature, wherein the cooling element and the at least one inlet of the egress passageway are configured such that the cooling element drives the hot air at a first flow rate and the cool air has a second flow rate greater than the first flow rate.
