Abstract

A pre-chilling heat sink driving device mainly improves the existing heat sink that simply uses the temperature change of a heat source of an electronic device as a parameter source to determine its rotary speed, and the present invention uses a parameter source that will affect the heat source to produce a temperature rise as the parameter source for accelerating the rotation of the heat sink if a temperature rise to the heat source of the electronic device is expected, and thus the invention normally maintains the heat source at a normal operating temperature to assure the operational performance.

Claims

1. A pre-chilling heat sink driving device, being applied to an electronic device having a heat source and a pair of heat sinks for lowering the temperature of said electronic device, and said electronic device including a drive circuit for controlling and lowering the temperature performance of said heat sink, characterized in that:

said drive circuit is coupled to a detection circuit, and said detection circuit obtains a detective signal from a parameter source that affects said heat source to produce a temperature rise, and said detective signal drives said detection circuit to output an acceleration signal or a deceleration signal to said drive circuit for controlling said heat sink to pre-chill and lower the temperature of said heat source in advance.

2. The pre-chilling heat sink driving device of claim 1, wherein said parameter source is a power source for supplying the electric power for the operation of said electronic device.

7. The pre-chilling heat sink driving device of claim 1, wherein said detective signal is an operation performance ratio signal of said heat source.

8. The pre-chilling heat sink driving device of claim 1, wherein said electronic device having a heat source and a pair of heat sinks for lowering the temperature of said electronic device is a power supply.

9. The pre-chilling heat sink driving device of claim 1, wherein said electronic device having a heat source and a pair of heat sinks for lowering the temperature of said electronic device is a computer system.

10. The pre-chilling heat sink driving device of claim 1, wherein said detection circuit or said drive circuit further detects said heat source for obtaining a temperature change signal.

11. The pre-chilling heat sink driving device of claim 1, wherein said drive circuit is controlled by a method comprising:

said heat sink maintaining a normal rotary speed or pausing its operation;

detecting whether the temperature of said heat source exceeds a temperature standard by pre-installing a temperature standard in said drive circuit for detecting said heat source;

if the temperature of said heat source is lower than said temperature standard, then said heat sink normally maintains a regular speed for its operation or stops operating to go to the next step;

if the temperature of said heat source is higher than said temperature standard, then said heat sink accelerates its rotary speed to lower the temperature or starts the operation of lowering the temperature; and

receiving a parameter change value by obtaining a parameter source that affects the temperature change of said heat source, and if the change value of a detective signal obtained from said parameter source increases, the rotary speed or initial operation of said heat sink suppresses the temperature rise of said heat source, and if said change value drops, then said heat sink maintains its current conditions and returns to a previous step for continuing its detection.

12. The pre-chilling heat sink driving device of claim 1, wherein said drive circuit is controlled by a method comprising:

said drive circuit obtaining a parameter source that affects the temperature change of said heat source if said heat sink maintains a normal rotary speed or pauses its operation;

said heat sink accelerating its rotary speed or starting the operation of suppressing the temperature rise of said heat source, if said parameter source detects an increase of said change value of a detective signal; and

said heat sink maintaining its current conditions and continuing its detection if said change value drops.
