Abstract
A cooling system for light emitting diodes (LEDs) is provided that may comprise acoustic baffle members, a micro-channel heatsink that includes fins adjacent to the LEDs, and a fluid flow generator adjacent to the micro-channel heatsink that directs a fluid in a flow direction. The fluid flow generator may include an input to receive the fluid and an exit to exhaust the fluid, which may contact a surface area of the fins. The sound emitted by the fluid flow generator may be substantially cancelled by the acoustic baffle members, which may reflect the sound to a source location as reflected sound waves defined by a substantially inverted phase.
