Abstract

A thermally managed power source (201) is provided herein which comprises a first battery module (203), and a first synthetic jet ejector (215) disposed on a surface of said first battery module and being adapted to direct a plurality of synthetic jets along a surface (211) of said first battery module.

Claims

1. A battery charger, comprising:

a base having a synthetic jet ejector disposed therein;

a platform supported on said base; and

a charging station incorporated into said platform, said charging station having a first major surface which is adapted to receive and charge at least one battery;

wherein said base has a planar surface for supporting said battery charger on a substrate, wherein said platform is disposed at an angle to said planar surface, wherein said charging station is powered by electrical circuitry disposed in said base, and wherein said synthetic jet ejector is adapted to direct a plurality of synthetic jets along a surface of said base.

2. The battery charger of claim 1, wherein said first major surface is spaced apart from said base.

3. The battery charger of claim 1, wherein said angle is within the range of about 15°

to about 75°

.

4. The battery charger of claim 1, wherein said angle is within the range of about 30°

to about 60°

.

5. The battery charger of claim 1, wherein said charging station has a first major surface which is adapted to receive and charge a plurality of batteries.

6. The battery charger of claim 5, wherein said first major surface is open to the ambient environment.

7. The battery charger of claim 1, wherein said base is supported on a plate, and wherein said plate has a plurality of apertures therein.

8. The battery charger of claim 7, wherein said plurality of apertures are in fluidic communication with a synthetic jet actuator.

9. The battery charger of claim 7, wherein said synthetic jet ejector is adapted to direct a plurality of synthetic jets along a surface of said base which is perpendicular to said base plate.

10. The battery charger of claim 7, wherein said plurality of apertures are spaced apart from the surface of said base.

11. The battery charger of claim 10, wherein said plate has a first portion which is covered by said base and a second portion which is not covered by said base, and wherein said plurality of apertures are disposed in said second portion of said plate.

12. The battery charger of claim 1, in combination with a battery, wherein said battery is disposed on said first major surface.

13. The battery charger of claim 1, in combination with a plurality of batteries, wherein said plurality of batteries are disposed on said first major surface.

14. The battery charger of claim 13, wherein said batteries are arranged in parallel on said first major surface.

15. The battery charger of claim 1, wherein said platform has a second major surface, and wherein said first and second major surfaces of said platform are opposing surfaces.
