BACKGROUND OF THE INVENTION

1. Fields of the Invention

The present invention relates to a heat dissipation device, and more particularly, to a warning system for a water-cooling heat dissipation device.

2. Descriptions of Related Art

The conventional warning system for a water-cooling heat dissipation device known to applicant is connected to the water source and water tank in series connection by a circulation pipe. The warning system further includes an illumination adjustment member, a light detection member, a circuit judgement member, a light emitting member and a warning member. The light emitting member emits a light beam which passes through a passage in which the illumination adjustment member is installed. The light beam reaches the light detection member located on one end of the passage, and a voltage value is therefore generated by the light beam received. The voltage value is compared with a standard voltage value to judge that the water-cooling heat dissipation device is operated normally or not.

The warning system activates the warning member go generates warning sound when the liquid stops to flow or the volume of the liquid is less than a pre-set value. However, there are multiple factors affecting eh fluid volume, such as the change of pressure, the change of temperature and scale attached to the pipe. Leakage is another factor that reduces the volume of the liquid, the liquid pressure and increases temperature. In other words, the users are not able to figure out the change in the internal circulation of the liquid.

When the users receive the warning sound due to the change of the liquid volume, it is too late to check out what exactly happens in time. The high temperature can damage the device in short time.

The present invention intends to provide a warning system for a water-cooling heat dissipation device which allows the users to check the device by multiple values to eliminate the shortcomings mentioned above.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring toFIGS. 1 to 6, the water-cooling heat dissipation device10of the present invention is installed in a case200having a transparent panel, and the water-cooling heat dissipation device10comprises a water tank11, a water source12, a pump13, a pressure detector14and a circulation pipe15. The circulation pipe15is connected to the water tank11, the water source12and the pump13. The water tank11includes at least one outlet/inlet111, and the pressure detector14is connected to the at least one outlet/inlet111and seals the at least one outlet/inlet111. The water source12is connected to a heat source20(CPUs or GPUs of a computer) to absorb heat from the heat source20. The pump13drives liquid between the water tank11and the water source12to dissipate heat. The pressure detector14detects the liquid in the water tank11and generates a pressure signal141.

A warning device30is connected to the circulation pipe15between the water tank11and the water source12. The warning device30includes a temperature detection unit31, a volume detection unit32, a receiving unit33, a processing unit34, a display unit35and a buzzer36. The temperature detection unit31detects the temperature of the liquid in the circulation pipe15to generate a temperature signal311. The volume detection unit32detects the speed of the liquid in the circulation pipe15to generate a volume signal321. The receiving unit33is wirelessly and electrically connected to the pressure detector14and receives the pressure signal141. The processing unit34includes a pre-set temperature value341, a pre-set volume value342and a pre-set pressure value343built therein. The pre-set temperature value341, the pre-set volume value342and the pre-set pressure value343are obtained after the system is operated stably for a period of time. The processing unit34receives and calculates the temperature signal311, the volume signal321and the pressure signal141to obtain a temperature calculation value, a volume calculation value and a pressure calculation value (not shown). The temperature calculation value, the volume calculation value and the pressure calculation value are respectively compared with the pre-set temperature value341, the pre-set volume value342and the pre-set pressure value343. When the temperature calculation value is larger than the pre-set temperature value341, the processing unit34sends the temperature calculation value to the display unit35and activates the buzzer36to buzz. When the volume calculation value is smaller than the pre-set volume value342, the processing unit34sends the volume calculation value to the display unit35and activates the buzzer36to buzz. When the pressure calculation value is smaller than the pre-set pressure value343, the processing unit34sends the pressure calculation value to the display unit35and activates the buzzer36to buzz.

That is to say, the processing unit34activates the buzzer36when either one of the factors as follows is detected, the factors are that the temperature calculation value is larger than the pre-set temperature value341, the volume calculation value is smaller than the pre-set volume value342, and the pressure calculation value is smaller than the pre-set pressure value343. The abnormal situations can be early found and fixed by the multiple factors mentioned above. Therefore, the heat source20can be stopped or operated to reduce the temperature thereof to protect the heat source20from being damaged by high temperature.

As shown inFIGS. 1 to 7, the processing unit34uses the temperature calculation values of the past 240 seconds to form a temperature curve3111along the axis, and the temperature curve3111is sent to the display unit35which alternatively displays the temperature curve3111and the latest temperature calculation value to acknowledge the users about the change of temperature for the past 240 seconds. Furthermore, the warning device30includes a warning light37which is electrically connected to the processing unit34. The warning light37is located opposite to the display unit35. When the temperature calculation value is larger than the pre-set temperature value341, the processing unit34sends the temperature calculation value to the display unit35and lights up the warning light37, as shown inFIG. 7. When the volume calculation value is smaller than the pre-set volume value342, the processing unit34sends the volume calculation value to the display unit35and lights up the warning light37. When the pressure calculation value is smaller than the pre-set pressure value343, the processing unit34sends the pressure calculation value to the display unit35and lights up the warning light37. When the temperature calculation value is smaller than the pre-set temperature value341, the display unit355is stopped to display. When the volume calculation value is larger than the pre-set volume value342, the display unit355is stopped to display. When the pressure calculation value is larger than the pre-set pressure value343, the display unit355is stopped to display. When the temperature calculation value is smaller than the pre-set temperature value341, the buzzer36is stopped to buzz. When the volume calculation value is larger than the pre-set volume value342, the buzzer36is stopped to buzz. When the pressure calculation value is larger than the pre-set pressure value343, the buzzer36is stopped to buzz. The pump13is located in the water tank11.

As shown inFIGS. 1-3 and 8, the processing unit34includes a pressure test value344built therein. The pressure detector14includes a one-way air inlet142through which pressurized air is introduced. The processing unit34calculates the pressure signal141after air is introduced from the one-way air inlet142to obtain the pressure calculation value, and the pressure calculation value is sent to the display unit35which displays the pressure calculation value. The processing unit34stops the pressurized air from entering via the one-way air inlet142when the buzzer36is activated to buzz due to that the pressure calculation value is larger than the pressure test value344. The processing unit34compares the pressure calculation value that is obtained by calculating the pressure signal141after 15 seconds from cancelation to the air introduced from the one-way air inlet142, with the pressure test value344. When the pressure calculation value is smaller than the pressure test value344more than 0.05 kg/cm2, the buzzer36is activated to buzz to provide a leakage warning.

The water-cooling heat dissipation device of the present invention effectively protects the heat source20from being damaged due to operation under high temperature. The life of the heat source20can last longer.
