Referring to fig. 3, the control unit 16 is connected to the sensing unit 15 and the first pump 102, and the control unit 16 is shown as a Programmable Logic Controller (PLC) in this embodiment, but is not limited thereto, and may be a Digital Signal Controller (DSC), a Digital Signal Processor (DSP) or a Microcontroller (MCU) in specific implementation. The control unit 16 compares the sensing signal with a preset ph range to generate a comparison result, and transmits the comparison result to an external interface 30, where the external interface 30 is represented as a monitoring system in this embodiment, and the external interface 30 is connected to the control unit 16 in a wireless transmission or wired transmission manner to receive the comparison result transmitted by the control unit 16. Wherein the predetermined pH range is preferably set to a pH of 1 to a pH of 14, for example, 5 to a pH of 6.5. In an embodiment, the external interface 30 may also be a display, a light emitting device set, an intelligent mobile device or a speaker, and the operation status of the liquid-cooled heat dissipation system 1 can be known in real time by displaying information, emitting a warning sound (or warning sound) or emitting a warning light source (or warning light) through the external interface 30.
Therefore, when the control unit 16 compares a PH value (e.g., PH7) of the sensing signal with a first predetermined PH value (e.g., PH6.5) in the predetermined PH range, if the PH value (e.g., PH7) of the sensing signal is greater than the first predetermined PH value (e.g., PH6.5) to generate the comparison result as a safe state, the external interface 30 is enabled to display the comparison result according to the comparison result transmitted by the control unit 16 through a display (not shown), so that a user can know that the current PH value of the water quality in the liquid cooling heat dissipation system 1 is in the safe state according to the comparison result information displayed by the display, thereby achieving the effect of monitoring the water quality in real time.
When the control unit 16 compares the PH value of the sensing signal with the first predetermined PH value (e.g., PH6.5) and the second predetermined PH value (e.g., PH6.0) in the predetermined PH range, if the PH value (e.g., PH6.3) of the sensing signal is smaller than the first predetermined PH value (e.g., PH6.5) and larger than the second predetermined PH value (e.g., PH6.0), the comparison result is a first alert state (e.g., yellow alert state), the external interface 30 is made to display through the display according to the comparison result transmitted by the control unit 16, so that the user can know that the current PH value of the water in the liquid cooling heat dissipation system 1 is in the first alert state from the comparison result information displayed by the display.

When the control unit 16 compares the PH value (e.g. PH4.9) of the sensing signal with the third predetermined PH value (e.g. PH5.0) in the predetermined PH range, if the PH value (e.g. PH4.9) of the sensing signal is smaller than the third predetermined PH value (e.g. PH5.0) to generate a comparison result as a shutdown state, the external interface 30 sends a shutdown signal to the control unit 16 of the liquid cooling heat dissipation system 1 while displaying the comparison result transmitted by the control unit 16, and the control unit 16 controls, for example, the first pump 102 to stop operating according to the shutdown signal, so that the user can know that the current PH value of the water quality in the liquid cooling heat dissipation system 1 is in the shutdown state from the comparison result information displayed by the display.
In one embodiment, the cabinet 60 and the external water supply device 40 may be two liquid-cooled heat dissipation systems 1 such as a chilled water host, wherein one of the liquid-cooled heat dissipation systems 1 is used as a backup, and when the currently operating liquid-cooled heat dissipation system 1 receives a shutdown signal sent by the external interface 30 to stop operating, the external interface 30 sends a start signal to control the other liquid-cooled heat dissipation system 1 to start operating, so as to continuously perform water-cooled circulation heat dissipation on the IT device of the cabinet 60. In another embodiment, the external interface 30 may also send operation information (e.g., comparison result information) of the liquid cooling heat dissipation system 1 corresponding to the dedicated machine room to an intelligent mobile device (e.g., a mobile phone or a tablet) of a remote user in a manner of short message, e-mail, APP information or communication software, so that the user can know the operation status of the liquid cooling heat dissipation system 1 of the cabinet 60 in each machine room in real time.
The liquid-cooled heat dissipation system 1 can exchange heat with liquid, automatically monitor the operation condition (including automatically monitoring the pH value of water) in the liquid-cooled heat dissipation system 1 and automatically send reminding or warning information, so the liquid-cooled heat dissipation system can be called an intelligent liquid-to-liquid heat exchange system (LTLCDU).

Therefore, the liquid-cooled heat dissipation system 1 can exchange heat with gas through liquid, and can automatically monitor the operation condition in the liquid-cooled heat dissipation system 1 and automatically send reminding or warning information, so that the liquid-cooled heat dissipation system can be called an intelligent liquid-to-gas heat exchange system (LTACDU).
