Abstract

A fan module is disclosed. The fan module includes a base, at least one first side coupled to the base, and a plurality of fans coupled to the base. The plurality of fans are configured to substantially disperse thermal energy away from one or more electronic components in an enclosure to maintain a current temperature of the one or more electronic components below a critical temperature. The fan module further includes a connector mounted on the at least one first side and coupled to provide power to the plurality of fans. When one of the plurality of fans ceases to operate, the remaining fans in the plurality of fans continue to substantially disperse thermal energy away from the one or more electronic components while maintaining the current temperature below the critical temperature.

Claims

1. A fan module, comprising:

a base;

at least one first side coupled to the base;

a plurality of fans coupled to the base, the plurality of fans configured to substantially disperse thermal energy away from one or more electronic components in an enclosure to maintain a current temperature of the one or more electronic components below a critical temperature;

a connector mounted on the at least one first side and coupled to provide power to the plurality of fans; and

wherein when one of the plurality of fans ceases to operate, the remaining fans in the plurality of fans continue to substantially disperse thermal energy away from the one or more electronic components while maintaining the current temperature below the critical temperature.

2. The fan module of claim 1, and further comprising at least one second side.

3. The fan module of claim 2, wherein the at least one second side comprises a plurality of openings, each opening associated with at least one of the plurality of fans to enable air flow from the fan to flow towards the one or more electronic components.

4. The fan module of claim 1, wherein the critical temperature does not exceed a prescribed component temperature operating range.

5. The fan module of claim 1, wherein the enclosure comprises a diagonstic indicator to indicate when one of the plurality of fans ceases to operate.

6. The fan module of claim 1, wherein the plurality of fans are operatively connected in parallel.

7. The fan module of claim 1, wherein the plurality of fans are variable-speed fans that operate at one or more fan speeds depending on the number of fans currently operable in the fan module.

8. The fan module of claim 1, wherein the plurality of fans are variable-speed fans that operate at one or more fan speeds depending on the temperature level recorded by the temperature sensor.

9. The fan module of claim 1, wherein the connector comprises a floating connection for the plurality of fans within the at least one first side.

10. The fan module of claim 9, wherein the floating connection is a floating blind-mate connection that mates with an internal connector in the enclosure as the base advances into the enclosure.

23. A method for maintaining component temperature in an electronic device, the method comprising:

substantially dispersing thermal energy away from one or more components in the electronic device with at least a portion of a cooling assembly;

if a portion of the cooling assembly ceases to operate;

notifying an operator that the cooling assembly requires replacement, and

continuing to operate the cooling assembly while the portion of the cooling assembly is inoperable; and

while the electronic device continues to function, replacing at least the failed portion of the cooling assembly before the component temperature exceeds a critical temperature.

24. The method of claim 23, and further comprising automatically activating the cooling assembly based on a prescribed temperature threshold level.

25. The method of claim 23, and further comprising monitoring the cooling assembly for potential failures.

26. The method of claim 23, wherein substantially dispersing thermal energy away from the one or more components comprises directing a plurality of fans in the cooling assembly at the one or more components.

27. The method of claim 23, wherein notifying the operator that the cooling assembly requires replacement comprises activating a diagnostic indicator on the electronic device.
