Abstract

A self-protection device of water-cooled heat dissipation system, applicable to a computer, includes a circulation route for a suitable amount of coolant flowing therein along a water tank, a pump and a heat exchanger; and a control module, electrically connected between the water-cooled heat dissipation system and a power supply of the computer system, for detecting whether if the water-cooled heat dissipation system is at a normal state. The control signal of the control module is to allow the computer turning on when the water-cooled heat dissipation system is checked normal. Otherwise, the power supply of the computer is stopped and an alarm is generated when the water-cooled heat dissipation system is abnormal.

Claims

1. A self-protection device of water-cooled heat dissipation system, applicable to a computer, for cooling heat-generating elements, comprising:

a circulation route, having a suitable coolant flowing therein, and connecting at least a tank, a pump and a heat exchanger; and

a control module, electrically connecting to the circulation route and a power supply of the computer for detecting if the water-cooled heat dissipation system is normal and outputting a correspondent signal to the power supply.

2. The self-protection device of water-cooled heat dissipation system according to claim 1 wherein the computer is one chosen from server and desktop computers.

3. The self-protection device of water-cooled heat dissipation system according to claim 1 wherein the control module comprises a flow detector for detecting coolant flowing rate and/or flowing volume in the circulation route.

4. The self-protection device of water-cooled heat dissipation system according to claim 1 wherein the control module comprises a level detector for detecting the reservoir of the coolant on the tank.

5. The self-protection device of water-cooled heat dissipation system according to claim 1 wherein the control module comprises a temperature detector for detecting temperature of the coolant.

6. The self-protection device of water-cooled heat dissipation system according to claim 1 wherein the water-cooled heat dissipation system further comprises a fan;

the control module comprises a tachometer for detecting revolution speed of the fan.

7. The self-protection device of water-cooled heat dissipation system according to claim 1 wherein the control module comprises a liquid crystal display (LCD) to show information of the water-cooled heat dissipation system and warnings.
