Abstract
A thermal management device (401) is provided which comprises a synthetic jet actuator (403) and a heat sink (405) comprising a fin (407). The fin has at least one interior channel (409) defined therein which has first and second openings that are in fluidic communication with each other. The synthetic jet actuator is adapted to direct a synthetic jet into said channel.
Claims20
A thermal management device, comprising:
- a synthetic jet actuator;
- and
- a heat sink comprising a plurality of fins, wherein any pair of adjacent fins has a space disposed between them;
- wherein each of said plurality of fins has first and second major surfaces, wherein each of said plurality of fins has defined in the interior thereof and between said first and second major surfaces a primary channel and a plurality of secondary channels, wherein said primary channel has a first opening which is in fluidic communication with said synthetic jet actuator, and wherein said primary channel is in fluidic communication with a space disposed between a pair of adjacent fins by way of said plurality of secondary channels.
