Abstract

In a method of thermal management, a temperature is sensed and compared with a first preset temperature. The lowest priority load is disabled in response to the temperature being equal to the first preset temperature.

Claims

1. A method of thermal management, comprising:

sensing a temperature;

comparing the temperature with a first preset temperature; and

disabling a lowest priority load in response to the temperature being equal to the first preset temperature.

2. The method according to claim 1, further comprising:

designating a second lowest priority load as the lowest priority load.

3. The method according to claim 2, further comprising:

sensing a second temperature;

comparing the second temperature with the first preset temperature; and

disabling the lowest priority load in response to the second temperature being equal or greater than the first preset temperature.

4. The method according to claim 1, further comprising:

comparing the temperature with a second preset temperature; and

enabling a highest priority load in response to the temperature being equal to or less than the second preset temperature.

5. The method according to claim 4, further comprising:

designating the previously second highest priority load as the highest priority load.

6. The method according to claim 4, further comprising:

sensing a second temperature;

comparing the second temperature with the second preset temperature; and

enabling the highest priority load in response to the second temperature being equal or less than the second preset temperature.

7. A system for thermal management, comprising:

a power supply;

a plurality of loads, each load connected to the power supply through an associated switch;

at least one temperature sensor; and

a controller configured to interface with the plurality of associated switches and at least one temperature sensor, wherein said controller is configured to enable and disable the plurality of loads based on a predetermined priority in response to data from the at least one temperature sensor.

8. The system according to claim 7, wherein the controller is configured to determine a temperature from the at least one temperature sensor and compare the temperature with a first preset temperature.

9. The system according to claim 8, wherein the controller is configured to disable the associated switch of a lowest priority load from the plurality of loads.

10. The system according to claim 9, wherein the controller is configured to determine a second temperature from the at least one temperature sensor and compare the second temperature with the first preset temperature.

11. The system according to claim 10, wherein the controller is configured to disable an associated switch of a second lowest priority load of the plurality of loads.

12. The system according to claim 7, wherein the controller is configured to determine a temperature from the at least one temperature sensor and compare the temperature with a second preset temperature.

13. The system according to claim 12, wherein the controller is configured to enable an associated switch of the highest priority load of the plurality of loads.

14. The system according to claim 13, wherein the controller is configured to sense a second temperature from the at least one temperature sensor and compare the second temperature with the second preset temperature.

15. The system according to claim 14, wherein the controller is configured to enable an associated switch with second highest priority load of the plurality of loads.
