Abstract
One embodiment of the cooling module is implemented as a device having a heat sink and an integrated synthetic jet actuator. The heat sink is configured to have a channel and a jet distribution system associated with the synthetic jet actuator directs fluid flow into the channel of the heat sink. In operation, the fluid flow of this embodiment of the cooling module comprises a synthetic jet stream and ambient fluid entrained into the channel by the synthetic jet stream. The fluid flowing through the channel serves to a wall of the heat sink channel.
Claims20
A cooling module, comprising:
- a heat sink having a channel;
- a synthetic jet actuator integrated with said heat sink, said synthetic jet actuator generating a fluid flow;
- and
- a jet distribution device associated with said synthetic jet actuator, said distribution device directing said fluid flow in the channel of said heat sink.
A method for cooling, comprising the steps of:
- providing a heat sink structure, said heat sink structure having a passage;
- generating a synthetic jet stream in said passage;
- entraining an ambient fluid into said passage due to the said synthetic jet stream such that a flow of ambient fluid is formed in said passage;
- and
- cooling a wall of said passage due to the flow of said ambient fluid.
A cooling device, comprising:
- a heat sink, said heat sink having a duct;
- a chamber integrated with said heat sink, said chamber defining a volume of fluid;
- an actuator for changing said volume of said chamber thereby causing a fluid to flow into and out of said chamber;
- and
- a fluid distributor connected to said chamber, said distributor having an orifice adjacent said duct such that a synthetic jet stream forms at said orifice and flows in said duct.
