Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown,

[0025] A cooling medium purification device for a cold plate system includes an inlet water main pipe 1, an inlet water monitoring pipe 2, an inlet water observation pipe 3, a reagent pipe 4, a dosing tank 5, a mixing tank 6, and an outlet water main pipe 7;

[0026] The main water inlet pipe 1, the water inlet monitoring pipe 2, and the mixing tank 6 are connected in sequence. The main water inlet pipe 1 is equipped with a water inlet on / off valve 101, and the water inlet monitoring pipe 2 is equipped with a turbidity meter 201, a pH meter 202, and a conductivity meter 203.

[0027] The main water inlet pipe 1, the water inlet observation pipe 3, and the mixing tank 6 are connected in sequence. The water inlet observation pipe 3 includes a water inlet observation straight pipe section 3.1. The water inlet observation straight pipe section 3.1 is provided with an observation front valve 301, an observation branch pipe 302, and an observation rear valve 303 arranged in sequence along the axial direction of the water inlet observation straight pipe section 3. One end of the observation branch pipe 302 is connected to the water inlet observation pipe 3. The other end of the observation branch pipe 302 is provided with a hanging plate cap 304 that is threadedly connected to the observation branch pipe 302. The hanging plate cap 304 is provided with an observation hanging plate 305. A vertically arranged drifting rod 306 is provided in the water inlet observation straight pipe section 3.1. The upper end of the drifting rod 306 is hinged to the observation hanging plate 305. The lower end of the drifting rod 306 is a limiting end. Two parallel limiting vertical plates 307 are provided in the water inlet observation straight pipe section 3.1. A limiting gap 307a is formed between the two limiting vertical plates 307, which allows the limiting end to enter.

[0028] The mixing tank 6 is connected to the water outlet main pipe 7, and the water outlet main pipe 7 is equipped with a water outlet on / off valve 701. The dosing tank 5, the chemical pipe 4 and the mixing tank 6 are connected in sequence, and the chemical pipe 4 is equipped with a dosing pump 401.

[0029] The dosing pump 401 can pre-add the chemicals from the dosing tank 5 into the mixing tank 6, which is pre-filled with deionized water. The chemicals in the dosing tank 5 can be commonly used chemicals in the field, such as hydrogen peroxide, dibromocyanoacetamide, alkyl dimethyl benzyl ammonium chloride, and benzalkonium chloride, to prevent the growth of biological slime and algae (the growth of biological slime and algae will have a negative impact on the turbidity, pH value, conductivity, etc. of the cooling medium).

[0030] When the detection device in the cold plate system (cold plate cooling system) detects that the parameters of the deionized water are not up to standard, the operator can connect the inlet pipe 1 of this invention to the outlet pipe of the cold plate system and the outlet pipe 7 of this invention to the inlet pipe of the cold plate system, using the pump built into the cold plate system to circulate the cooling medium (deionized water). The deionized water and reagents in the mixing tank 6 will enter the cold plate system pipeline through the outlet pipe 7, and the deionized water in the cold plate system pipeline will enter the inlet pipe 1. Part of the deionized water in the inlet pipe 1 enters the inlet monitoring pipe 2 and then enters the mixing tank 6, and the other part enters the inlet observation pipe 3 and then enters the mixing tank 6. The deionized water entering the inlet monitoring pipe 2 is monitored in real time by a turbidity meter 201, a pH meter 202, and a conductivity meter 203. Once the parameters are normal, the operation of this invention can be stopped. Then, this invention can be separated from the outlet and inlet pipes of the cold plate system, restoring the cooling circulation pipeline of the cold plate system. This invention can then be moved to other cold plate systems requiring cooling medium purification. The deionized water entering the inlet observation pipe 3 flows through the observation plate 305 hanging on the hanging plate cap 304. The observation plate 305 itself is existing technology. If necessary, an observation window can be opened on the inlet observation pipe 3 to visually observe changes on the hanging plate, assisting in determining if there is a problem with the cooling medium. The observation plate 305 can also be removed and tested using conventional instruments such as microscopes, spectrophotometers, and ATP bioluminescence detectors to assist in determining whether the cooling medium of the cold plate system is qualified. The specific method for removing the observation plate 305 is as follows: close the observation front valve 301 and the observation rear valve 303, rotate the plate cap 304 to separate it from the observation branch pipe 302 (the plate cap 304 is threadedly connected to the observation branch pipe 302), and then remove the plate cap 304 and the observation plate 305 (the plate cap 304 is equipped with the observation plate 305).

[0031] To prevent operators from removing the observation plate 305 without closing the relevant valves (if the plate cap 304 is rotated without closing the relevant valves, and the rotation is too large, the seal between the plate cap 304 and the observation branch pipe 302 will be broken, and the cooling medium will leak abnormally), this solution includes a drift rod 306 structure. When the relevant valves such as the observation front valve 301 and observation rear valve 303 are not closed, the liquid will continue to flow in the inlet observation straight pipe section 3.1, and the lower end (limiting end) of the drift rod 306 will drift with the liquid flow. The limiting end will be between the two limiting vertical plates 307 (within the limiting gap 307a). In this way, the limiting vertical plates 307 will prevent the drift rod 306 from rotating together with the observation plate 305 and the plate cap 304, thereby preventing abnormal leakage of the cooling medium between the plate cap 304 and the observation branch pipe 302 (serving as a protective limit).

[0032] When the relevant valves such as the observation valve 301 and the observation valve 303 are closed, the liquid in the water inlet observation straight pipe section 3.1 gradually becomes still. Under the action of gravity, the drift rod 306 remains vertical, and the limiting vertical plate 307 no longer restricts the drift rod 306 from rotating together with the observation hanging plate 305 and the hanging plate cap 304. At this time, after the operator rotates the hanging plate cap 304 normally, the hanging plate cap 304 can be allowed to leave the observation branch pipe 302 together with the observation hanging plate 305 and the drift rod 306. After observation and testing are completed, the hanging cap 304 can be reinstalled on the observation branch pipe 302. It should be noted that after the hanging cap 304 is installed, once the relevant valves such as the observation front valve 301 and observation rear valve 303 are opened, the limiting end of the drift rod 306 should be able to enter the limiting gap 307a under the action of the liquid. Therefore, a simple method such as setting alignment marks on the hanging cap 304 and the observation branch pipe 302 can be used to allow the operator to quickly determine whether the hanging cap 304 is installed in place.

[0033] The observation branch pipe 302 is arranged vertically. A sealing ring 308 is provided on the hanging plate cap 304. The sealing ring 308 is in sealing contact with the observation branch pipe 302. A hanging plate connecting rod 309 is provided on the hanging plate cap 304. The observation hanging plate 305 is connected to the hanging plate cap 304 through the hanging plate connecting rod 309. A part of the observation hanging plate 305 is located inside the water inlet observation pipe 3.

[0034] The sealing ring 308 can further enhance the sealing effect, and the sealing ring 308 has a certain degree of elasticity, which can provide a certain degree of sealing redundancy.

[0035] The observation valve 301 is an on / off valve, and the observation valve 303 is a one-way valve. The liquid passes through the observation valve 301, the drift rod 306 and the observation valve 303 in sequence in the water inlet observation pipe 3.

[0036] The post-observation valve 303 is a one-way valve, which helps to eliminate backflow at the post-observation valve 303. The pre-observation valve 301 is used to control the flow of liquid at the inlet observation pipe 3. Once this is set up, before removing the observation bracket 305, only the pre-observation valve 301 needs to be closed, which is more convenient and safer.

[0037] The water inlet observation straight pipe section 3.1 is axially horizontal and parallel to the limiting vertical plate 307. The rotation center line of the drift rod 306 is horizontal and perpendicular to the limiting vertical plate 307. When the limiting end is within the limiting gap 307a, the distance between the limiting end and any limiting vertical plate 307 is less than 1.5 mm.

[0038] The small distance between the limiting end and the limiting vertical piece 307 effectively protects the limiting action. The slight allowance also means that the positioning of the hanging cap 304 does not need to be extremely precise, reducing the installation difficulty of the hanging cap 304.

[0039] The main water inlet pipe 1 is equipped with a front pressure gauge 102, a filter 103, a water flow switch 104 and a rear pressure gauge 105 arranged sequentially along the liquid flow direction inside the main water inlet pipe 1.

[0040] The filter 103 can assist in water purification and maintain water quality to a certain extent. The flow switch 104 is existing technology and is used for auxiliary detection. The pre-pressure gauge 102 and the post-pressure gauge 105 are used to detect the liquid pressure at the front end and the rear end of the filter 103.

[0041] The mixing tank 6 is equipped with a microcrystalline bypass water processor 601 and a drain pipe 602 connected to the mixing tank 6. The drain pipe 602 is equipped with a drain valve 603 and a flow meter 604.

[0042] Theoretically, this invention does not produce concentrated wastewater or other wastewater. However, considering the possibility of contamination from impurities, the drain pipe 602 can still function as a drain. The microcrystalline bypass water processor 601 is existing technology and can assist in descaling the cooling system.

[0043] It also includes a maintenance vehicle 8, which is equipped with an installation box 801. The water inlet main pipe 1, water inlet monitoring pipe 2, water inlet observation pipe 3, chemical pipe 4, chemical dosing tank 5, mixing tank 6 and water outlet main pipe 7 are all installed in the installation box 801. The installation box 801 is equipped with a water inlet quick connector 802 that connects to the water inlet main pipe 1 and a water outlet quick connector 803 that connects to the water outlet main pipe 7.

[0044] As mentioned earlier, "Once the parameters are normal, the operation of this utility model can be stopped. Then, this utility model can be separated from the water outlet and water inlet pipes of the cold plate system, restoring the cooling circulation pipeline of the cold plate system itself. This utility model can then be moved to other cold plate systems that require cooling medium purification." With the maintenance vehicle 8 structure, the aforementioned process can be completed more conveniently. The quick connector 802 for the water inlet pipe and the quick connector 803 for the water outlet pipe are existing technologies, allowing operators to easily connect or disconnect this utility model from the water outlet and water inlet pipes of the cold plate system.

[0045] The embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
