The present invention relates to a heat dissipation device, and more particularly, to a warning system for a water-cooling heat dissipation device.
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.
The present invention relates to a water-cooling heat dissipation device and comprises a water tank, a water source, a pump, a pressure detector and a circulation pipe. The circulation pipe is connected to the water tank, the water source and the pump. The water tank includes at least one outlet/inlet. The pressure detector is connected to the at least one outlet/inlet and seals the at least one outlet/inlet. The water source is connected to a heat source to absorb heat from the heat source. The pump drives liquid between the water tank and the water source to dissipate heat. The pressure detector detects the liquid in the water tank and generates a pressure signal.
A warning device is connected to the circulation pipe between the water tank and the water source. The warning device includes a temperature detection unit, a volume detection unit, a receiving unit, a processing unit, a display unit and a buzzer. The temperature detection unit detects the temperature of the liquid in the circulation pipe to generate a temperature signal. The volume detection unit detects the speed of the liquid in the circulation pipe to generate a volume signal. The receiving unit is wirelessly and electrically connected to the pressure detector and receives the pressure signal. The processing unit includes a pre-set temperature value, a pre-set volume value and a pre-set pressure value built therein. The processing unit receives and calculates the temperature signal, the volume signal and the pressure signal to obtain a temperature calculation value, a volume calculation value and a pressure calculation value. The temperature calculation value, the volume calculation value and the pressure calculation value are respectively compared with the pre-set temperature value, the pre-set volume value and the pre-set pressure value.
When the temperature calculation value is larger than the pre-set temperature value, the processing unit sends the temperature calculation value to the display unit and activates the buzzer to buzz. When the volume calculation value is smaller than the pre-set volume value, the processing unit sends the volume calculation value to the display unit and activates the buzzer to buzz. When the pressure calculation value is smaller than the pre-set pressure value, the processing unit sends the pressure calculation value to the display unit and activates the buzzer to buzz.
The primary object of the present invention is to provide a warning system for a water-cooling heat dissipation device, wherein the temperature signal, the volume signal and the pressure signal are monitored to protect water-cooling heat dissipation device by high temperature.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
Referring to
A warning device 30 is connected to the circulation pipe 15 between the water tank 11 and the water source 12. The warning device 30 includes a temperature detection unit 31, a volume detection unit 32, a receiving unit 33, a processing unit 34, a display unit 35 and a buzzer 36. The temperature detection unit 31 detects the temperature of the liquid in the circulation pipe 15 to generate a temperature signal 311. The volume detection unit 32 detects the speed of the liquid in the circulation pipe 15 to generate a volume signal 321. The receiving unit 33 is wirelessly and electrically connected to the pressure detector 14 and receives the pressure signal 141. The processing unit 34 includes a pre-set temperature value 341, a pre-set volume value 342 and a pre-set pressure value 343 built therein. The pre-set temperature value 341, the pre-set volume value 342 and the pre-set pressure value 343 are obtained after the system is operated stably for a period of time. The processing unit 34 receives and calculates the temperature signal 311, the volume signal 321 and the pressure signal 141 to 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 value 341, the pre-set volume value 342 and the pre-set pressure value 343. When the temperature calculation value is larger than the pre-set temperature value 341, the processing unit 34 sends the temperature calculation value to the display unit 35 and activates the buzzer 36 to buzz. When the volume calculation value is smaller than the pre-set volume value 342, the processing unit 34 sends the volume calculation value to the display unit 35 and activates the buzzer 36 to buzz. When the pressure calculation value is smaller than the pre-set pressure value 343, the processing unit 34 sends the pressure calculation value to the display unit 35 and activates the buzzer 36 to buzz.
That is to say, the processing unit 34 activates the buzzer 36 when either one of the factors as follows is detected, the factors are that the temperature calculation value is larger than the pre-set temperature value 341, the volume calculation value is smaller than the pre-set volume value 342, and the pressure calculation value is smaller than the pre-set pressure value 343. The abnormal situations can be early found and fixed by the multiple factors mentioned above. Therefore, the heat source 20 can be stopped or operated to reduce the temperature thereof to protect the heat source 20 from being damaged by high temperature.
