Abstract

Claims (35)

1. A thermal management system, comprising:

a substrate;

a synthetic jet ejector; and

a vibration isolation element adapted to releasably engage said synthetic jet ejector and said substrate;

wherein said vibration isolation element comprises a flexible beam having a first pair of protrusions adapted to releasably engage said substrate, and a second pair of protrusions adapted to releasably engage said synthetic jet ejector.

2. The thermal management system of claim 1 , wherein said synthetic jet ejector is equipped with at least one slot, and wherein vibration isolation element is equipped with at least one member that releasably engages said slot.

3. The thermal management system of claim 1 , wherein said vibration isolation element comprises a base having first and second protrusions extending therefrom, and wherein said first and second protrusions engage first and second slots, respectively, which are provided in said synthetic jet ejector.

4. The thermal management system of claim 3 , wherein said base is attached to said substrate by way of at least one fastener.

5. The thermal management system of claim 3 , wherein said base is attached to said substrate by way of at least one grommet.

6. The thermal management system of claim 5 , wherein said at least one grommet comprises a head which is in contact with said base.

7. The thermal management system of claim 1 , wherein said substrate comprises a heat sink.

8. The thermal management system of claim 7 , wherein said heat sink comprises a base having a plurality of fins attached thereto.

9. The thermal management system of claim 8 , wherein said vibration isolation element is adapted to orient said synthetic jet ejector with respect to said heat sink such that the synthetic jet ejector produces a synthetic jet whose longitudinal axis is directed between said plurality of fins.

10. The thermal management system of claim 1 , wherein said substrate is equipped with first and second forked elements which releasably engage said second pair of protrusions.

11. The thermal management system of claim 10 , wherein each of said second pair of protrusions comprises a cylindrical element connected to said beam by way of a neck.

12. The thermal management system of claim 11 , wherein said neck is cylindrical and has a smaller diameter than said cylindrical element.

13. The thermal management system of claim 1 , wherein said synthetic jet ejector comprises an upper portion and a lower portion, wherein said second pair of protrusions comprises a first protrusion adapted to releasably engage a first aperture disposed in said upper portion, and wherein said second pair of protrusions further comprises a second protrusion adapted to releasably engage a second aperture disposed in said lower portion.

14. The thermal management system of claim 13 , wherein each of said protrusions in said second pair of protrusions has an essentially elliptical cross-section.

15. The thermal management system of claim 1 , wherein said synthetic jet ejector comprises an upper portion and a lower portion, and wherein said beam is equipped with first and second longitudinal grooves which are adapted to mate with said upper and said lower portions, respectively.

16. The thermal management system of claim 15 , wherein said flexible beam contains a flat face which abuts each of said first and second longitudinal grooves.

17. A thermal management system, comprising:

a substrate;

a synthetic jet ejector housing comprising top and bottom portions; and

a vibration isolation element adapted to releasably engage each of said top and bottom portions and said substrate;

wherein each of said top and bottom portions contains a tab having a slot therein, and wherein said vibration isolation element is equipped with a first set of protrusions adapted to releasably engage the slot in the tabs of each of said top and bottom portions.

18. The thermal management system of claim 17 , wherein each of the members of said first set of protrusions are complimentary in shape to the slot in the tabs of each of said top and bottom portions.

19. The thermal management system of claim 18 , wherein said vibration isolation element further comprises a longitudinal beam, and wherein said first set of protrusions are mounted on said beam.

20. The thermal management system of claim 19 , wherein the first set of protrusions comprises first and second members which are mounted on opposing sides of said beam.

21. The thermal management system of claim 17 , wherein said vibration isolation element is further equipped with a second set of protrusions, and wherein said substrate is equipped with first and second forked elements which releasably engage said second set of protrusions.

22. The thermal management system of claim 21 , wherein each of said first set of protrusions comprises a cylindrical element connected to said beam by way of a neck.

23. The thermal management system of claim 22 , wherein said neck is cylindrical and has a smaller diameter than said cylindrical element.

24. The thermal management system of claim 19 , wherein said synthetic jet ejector comprises an upper portion and a lower portion, and wherein said beam is equipped with first and second longitudinal grooves adapted to mate with said upper and said lower portions, respectively.

25. The thermal management system of claim 24 , wherein said beam contains a flat face which abuts each of said first and second longitudinal grooves.

26. The thermal management system of claim 1 , wherein said synthetic jet ejector comprises (a) a housing having an orifice defined therein, and (b) a diaphragm in fluidic communication with said orifice.

27. The thermal management system of claim 17 , wherein said synthetic jet ejector comprises (a) a housing having an orifice defined therein, and (b) a diaphragm in fluidic communication with said orifice.
