Abstract

A bi-directional fan device that is field replaceable within an electronic system is provided. The bi-directional fan device includes a fan unit that cools an electronic system when connected to a power source, and an electrical connector constructed at both ends of the fan unit to electrically connect to the power source.

First claim

The invention claimed is:

1. A bi-directional fan device comprising:
a fan unit configured to direct air via a body of the fan unit in a first direction;
a first electrical connector positioned at a first end of the body of the fan unit, wherein the first electrical connector is configured to electrically connect the fan unit to a power source in a first configuration; and
a second electrical connector positioned at a second end of the body of the fan unit opposite the first end, wherein the second electrical connector is configured to electrically connect the fan unit to the power source in a second configuration; and
a removable chassis, wherein, in the second configuration, the removable chassis is removably attached to the first end of the fan body and configured to prevent electrical connection with the first electrical connector.

2. The bi-directional fan device according to claim 1 , wherein at least a portion of the removable chassis is configured to allow air to pass therethrough.

3. The bi-directional fan device according to claim 1 , wherein the removable chassis further comprises a handle.

4. The bi-directional fan device according to claim 1 , wherein the removable chassis further comprises a mechanism configured to removably secure the chassis to the body of the fan unit.

5. The bi-directional fan device according to claim 1 , wherein the removable chassis further comprises a mechanism for providing a visual indication of the first direction in which air is directed by the fan unit.

6. The bi-directional fan device according to claim 5 , wherein the mechanism for providing the visual indication further comprises a colored pin.

7. The bi-directional fan device according to claim 1 , wherein the fan unit is configured to draw air through the removable chassis from the fan unit.

8. The bi-directional fan device according to claim 1 , wherein the fan unit is configured to direct air from the fan unit toward the removable chassis.

9. The bi-directional fan device according to claim 1 , wherein the body of the fan unit defines one or more holes configured to receive corresponding pins of the removable chassis.

10. The bi-directional fan device according to claim 9 , further comprising one or more springs sheathed along the corresponding pins of the removable chassis.

11. The bi-directional fan device according to claim 1 , wherein the first electrical connector and the second electrical connector are co-planar.

12. The bi-directional fan device according to claim 1 , wherein the first electrical connector is positioned in a plane that is substantially parallel with respect to a plane defined by the second electrical connector.

13. The bi-directional fan device according to claim 1 , wherein each of the first electrical connector and the second electrical connector defines a plurality of metallic contacts.

14. The bi-directional fan device according to claim 1 , wherein the removable chassis further comprises one or more anchors configured to maintain engagement between the fan unit and the removable chassis.

15. A bi-directional fan device comprising:
a fan unit configured to direct air via a body of the fan unit in a first direction;
a first electrical connector positioned at a first end of the body of the fan unit, wherein the first electrical connector is configured to electrically connect the fan unit to a power source in a first configuration; and
a second electrical connector positioned at a second end of the body of the fan unit opposite the first end, wherein the second electrical connector is configured to electrically connect the fan unit to the power source in a second configuration; and
a removable chassis, wherein, in the first configuration, the removable chassis is removably attached to the second end of the fan body and configured to prevent electrical connection with the second electrical connector.

16. The bi-directional fan device according to claim 15 , wherein at least a portion of the removable chassis is configured to allow air to pass therethrough.

17. The bi-directional fan device according to claim 15 , wherein the removable chassis further comprises a handle.

18. The bi-directional fan device according to claim 15 , wherein the removable chassis further comprises a mechanism configured to removably secure the chassis to the body of the fan unit.

19. The bi-directional fan device according to claim 15 , wherein the removable chassis further comprises a mechanism for providing a visual indication of the first direction in which air is directed by the fan unit.

20. The bi-directional fan device according to claim 19 , wherein the mechanism for providing the visual indication further comprises a colored pin.
