Description

Liquid cooling heat dissipation system capable of regulating and controlling water quality

Technical Field

The invention relates to a liquid cooling heat dissipation system, in particular to a liquid cooling heat dissipation system which can monitor the pH value of water quality so as to adjust and control the pH value of the water quality and can regulate and control the water quality.

Background

The advancement of technology can improve the convenience of human life, especially the operation of various data processing and internet networks at present, so that the electronic equipment with high-speed processing efficiency and large energy storage capacity is widely used in various enterprises.

The conventional existing structure of a chassis (cabinet) capable of accommodating various heating elements such as IT, communication, industry, transportation, etc. is described, the interior of the chassis (cabinet) is a closed accommodating space for accommodating a plurality of heating elements (such as a Central Processing Unit (CPU), a microprocessor, a chip, a single chip, or other units or devices generating heat sources due to electric drive, etc.), and a plurality of water-cooling heads are arranged in the accommodating space and attached to the heating elements, and a pipe group and a pump are used to bring a working fluid inside the chassis (cabinet) to a water discharge position, and the air in the accommodating space of the chassis (cabinet) is driven by a fan arranged inside the chassis (cabinet) so that the working fluid absorbing heat in the water discharge and the air inside the chassis (cabinet) perform a heat exchange effect to achieve a heat dissipation effect and reduce the temperature of the heating elements.

However, the heat dissipation cycle process is only to perform heat exchange heat dissipation inside the case (cabinet), a plurality of high-power cpus are disposed inside the case (cabinet), and the temperature of the water discharged through the water discharge and the fan disposed inside the case (cabinet) is relatively high, and further because the case (cabinet) is a closed space, the hot gas is retained inside the case (cabinet) and cannot be discharged, which is likely to cause vicious cycle of continuous decrease of the overall heat dissipation efficiency and failure of instant heat dissipation, resulting in poor heat dissipation effect and poor heat exchange efficiency. In addition, after the working fluid in the water cooling row is subjected to heat exchange for a period of time, the PH of the working fluid is gradually changed into peracid (i.e. the PH is too low to be below PH5.0, so that the tube body and the water cooling row are seriously corroded, and the service life of the whole body is reduced.

Therefore, how to solve the above-mentioned problems and disadvantages is a direction in which the inventors of the present invention and related manufacturers engaged in the industry need to research and improve.

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, regulate and control the pH value of water quality and automatically send reminding or warning messages, so the liquid-cooled heat dissipation system can be called as an intelligent liquid-to-gas heat exchange system (LTACDU).

Therefore, a user can display the measured temperature value by means of the display according to the temperature sensing signal transmitted by the control unit 16 received by the external interface 30, so that the user can timely transmit a control signal to the control unit 16 through the external interface 30, and the control unit 16 controls the water control valve 181 to control the water flow of the second liquid inlet 13 according to the control signal.

Therefore, through the design of the liquid cooling heat dissipation system 1, the effect of adjusting and controlling the water quality, prolonging the service life of the liquid cooling heat dissipation system and improving the heat exchange efficiency can be achieved by timely and manually or automatically adding chemicals to monitor the water quality (such as the pH value of the water quality), and the effects of warning and reminding, controlling the water flow of the working liquid, automatically supplementing water and monitoring the pressure of the system can be achieved.

The structure, connection relationship and efficacy of this embodiment are substantially the same as those of the first embodiment, and will not be described again, and the differences are: the sensing unit 15 is provided with at least one pressure sensor 152, and in this embodiment, the docking port 105 of the heat exchange unit 10 of the first embodiment is disposed on the first fluid pipeline 191 adjacent to the first fluid inlet 11 instead of the drug outlet 213 docked with the corresponding water quality control unit 21, so that the effect of uniformly mixing the drug with the high-temperature first working fluid 51 passing through the first fluid pipeline 191 adjacent to the first fluid inlet 11 can be effectively accelerated.

The pressure sensor 152 is disposed at a position through which the working fluid (such as the first and second working fluids 51, 52) passes to measure the pressure in the pipeline 193 in the liquid-cooled heat dissipation system 1, for example, the pressure sensor 152 is configured to sense at least one of the first fluid inlet 11 (or the second fluid inlet 13), the first fluid outlet 12 (or the second fluid outlet 14) and the plurality of first fluid pipelines 191 (or the second fluid pipelines 192) to obtain a pressure sensing signal, and in the pressure sensor 152 of this embodiment, two pressure sensors 152 are respectively disposed at a position adjacent to the second fluid pipeline 192 corresponding to the second fluid inlet 13 and at a position adjacent to the second fluid pipeline 192 corresponding to the second fluid outlet 14 to measure the pressure value of the low-temperature second working fluid 52 entering from the second fluid inlet 13 and the pressure value of the high-temperature second working fluid 52 discharged from the second fluid outlet 14, and transmits the pressure value to the control unit 16, so that the control unit 16 transmits the received pressure value to the external interface 30 (such as a monitoring system) for displaying, and a user can adjust or control the operation in the liquid-cooled heat dissipation system 1.

When at least one water level sensor 154 disposed in the reservoir 104 senses that the water level inside the reservoir 104 is lower than the set water amount, the water level sensor 154 transmits a water level sensing signal to the control unit 16, the control unit 16 controls a water control valve (not shown) on the water replenishing unit 20 to open, and the water replenishing unit 20 performs water replenishing (such as replenishing cooling liquid), until the water level sensor 154 detects that the water level inside the reservoir 104 has been replenished to reach the set water amount, the control unit 16 controls the water control valve on the water replenishing unit 20 to close to stop water replenishing, so as to achieve the effect of automatic water replenishing. In addition, in practical implementation of the present invention, since the water replenishing unit 20 can dilute (or increase) the acid-base concentration of the original first working fluid 51 during the automatic water replenishing process, the control unit 16 can compare the sensing signal transmitted by the ph sensor 151 with the predetermined ph range to generate a comparison result, so as to adjust and control the water quality adjusting unit 21 to send out the medicament to the reservoir 104 according to the comparison result, so that the first working fluid 51 replenished in the reservoir 104 reaches the predetermined ph range.
