MEMS based cooling systems having an integrated spout

A method, comprising:

• activating an active component to undergo vibrational motion, the vibrational motion of the active component transferring fluid from a high pressure region to an ambient pressure region via an egress, the vibrational motion inducing a pulsating pressure in the fluid, the active component being in a chamber having an inlet and the egress, a channel region receiving the fluid from the egress, at least a portion of the channel region adjacent to and extending along the chamber, a first portion of the channel region having a channel region dimension in a first direction, the vibrational motion of the active component drawing the fluid into the chamber through the inlet, driving the fluid out of the chamber through the egress, the vibrational motion of the active component inducing the pulsating pressure in the fluid in the channel region;
• wherein the fluid passes from the channel through a dissipation region extending at least one millimeter and not more than 5.5 millimeters beyond an outer edge of the chamber, at least a portion of the dissipation region having a dissipation region dimension in the first direction, the dissipation region dimension being greater than the channel region dimension, pulsations in the pulsating pressure are dissipated such that a pressure at a location where the fluid is introduced to the ambient does not pulsate and such that turbulence is reduced below a first turbulence at the location where the fluid is introduced to the ambient pressure region, the first turbulence being for a channel region exit of the heat transfer system in the absence of the dissipation region, the turbulence corresponding to a more laminar flow than the first turbulence;
• wherein at least part of the dissipation region is formed by a spout coupled with the chamber, a portion of the spout extending over a portion the chamber and over a second portion of the channel region.
