[0072] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0073] In the application of using liquid cooling technology to dissipate heat for servers, as the coolant is used for a longer time, impurities such as scale, rust, and silicate deposits may appear in the coolant. Therefore, it is necessary to remove the impurities in the coolant. Usually, in traditional technology, impurities are removed by adding a composite agent to the coolant to remove impurities. However, this method cannot completely remove all impurities in the coolant; or, the coolant is replaced. However, this method is relatively expensive. In view of this, the present application proposes a coolant treatment device to improve the flexibility of the coolant treatment method.

[0074] In an exemplary embodiment, Figure 1 As shown, a coolant treatment device is provided, comprising:

[0075] The purification component 10 has a first end connected to a liquid inlet of the coolant treatment device.

[0076] The filter assembly 20 has a first end connected to the second end of the purification assembly 10 , and a second end connected to the liquid outlet of the coolant treatment device.

[0077] The controller 30 is connected to the purification component 10 and the filtering component 20 respectively. The controller 30 is used to control the purification component 10 to purify the coolant entering the coolant treatment device from the liquid inlet, and / or control the filtering component 20 to filter the coolant.

[0078] The coolant treatment device is a treatment device for purifying and / or filtering the coolant to remove impurities from the coolant. The liquid inlet refers to the entrance for the external coolant to enter the coolant treatment device. The liquid outlet refers to the outlet for discharging the treated coolant from the coolant treatment device. It is understood that the liquid inlet and the liquid outlet of the coolant treatment device can be connected to the secondary side pipeline of the liquid cooling system function respectively to treat the coolant in the secondary side pipeline.

[0079] Wherein, the purification component 10 refers to a processing component that uses physical or chemical methods to filter out impurities in the coolant to improve the purity of the coolant. Optionally, the purification component 10 can perform physical purification treatment, or the purification component 10 can also perform chemical treatment. In this embodiment, the purification component 10 can be set in the coolant treatment device, and the first end of the purification component 10 is connected to the liquid inlet of the coolant treatment device to purify the coolant entering through the liquid inlet. It should be noted that when the current carrying rate of ions in the coolant is greater than the preset conductivity threshold, the purification component 10 can be used to purify the coolant.

[0080] The filter component 20 refers to a processing component that purifies the coolant using a physical method. In this embodiment, the filter component 20 can be set in the coolant processing device, and the first end of the filter component 20 can be connected to the second end of the purification component 10, and the second end of the filter component 20 can be connected to the liquid outlet, so that the coolant entering through the purification component 10 can be filtered and the filtered coolant can be discharged through the liquid outlet. It should be noted that when the proportion of impurities in the coolant exceeds the preset impurity threshold, the filter component 20 can be used to filter the coolant.

[0081] In the process of purifying the coolant using the purification component 10 and / or filtering the coolant using the filtering component 20, the purification component 10 and the filtering component 20 can be controlled by the controller 30, so as to realize the automatic processing of the coolant. In this embodiment, the controller 30 can be connected to the purification component 10 and the filtering component 20 respectively. When the carrying rate of ions in the coolant is greater than a preset threshold, the purification component 10 can be controlled by the controller 30 to purify the coolant, and / or, when the proportion of impurities in the coolant exceeds a preset threshold, the filtering component 20 can be controlled by the controller 30 to filter the coolant.

[0082] As a possible implementation, the controller 30 may control the purification component 10 and the filtering component 20 to process the coolant at the same time, or the controller 30 may control the purification component 10 to purify the coolant and control the filtering component 20 to stop filtering the coolant, or the controller 30 may control the purification component 10 to stop purifying the coolant and control the filtering component 20 to filter the coolant.

[0083] The above-mentioned coolant treatment device includes a purification component, a filtering component and a controller. The first end of the purification component is connected to the liquid inlet of the coolant treatment device, the first end of the filtering component is connected to the second end of the purification component, the second end of the filtering component is connected to the liquid outlet of the coolant treatment device, and the controller is connected to the purification component and the filtering component respectively. The controller is used to control the purification component to purify the coolant entering the coolant treatment device from the liquid inlet, and / or control the filtering component to filter the coolant. Since the purification component and the filtering component are integrated in the coolant treatment device, and the purification component and / or the filtering component are filtered by the controller, the coolant entering the coolant treatment device can be purified and / or filtered, so that the coolant treatment device can be used to achieve multiple treatments of the coolant, and the coolant treatment device can be used to improve the flexibility of the coolant treatment method.

[0084] Based on the above embodiments, in one embodiment, Figure 2 As shown, the purification component 10 comprises:

[0085] The conductivity sensor 101 has a first end connected to the liquid inlet.

[0086] The purification device 102 has a first end connected to the second end of the conductivity sensor 101 , and a second end of the purification device 102 is connected to a first end of the filter assembly 20 .

[0087] The controller 30 is connected to the purification device 102 and the conductivity sensor 101 respectively. The controller 30 is specifically used to control the conductivity sensor 101 to measure the conductivity of the coolant, and control the purification device 102 to purify the coolant according to the conductivity.

[0088] Among them, the conductivity sensor 101 is a detection device for measuring the conductivity in the coolant, that is, detecting the ion concentration in the coolant to obtain the concentration and conductivity of the ions in the coolant. For example, the degree of contamination of the coolant can be determined by measuring the concentration of different ions in the coolant. In this embodiment, the conductivity sensor 101 is connected to the controller 30, and the conductivity measured by the conductivity sensor 101 can be sent to the controller 30 to monitor the conductivity in the coolant. It can be understood that the greater the ion concentration in the coolant, the stronger the conductivity. The appropriate conductivity can ensure that the ion concentration in the coolant is moderate, thereby avoiding the problem of electrochemical corrosion caused by excessive or low ion concentration. Moreover, the high conductivity coolant may cause more energy to be lost in the form of heat energy, affecting the cooling effect. Therefore, if the conductivity in the coolant is relatively high, it is necessary to filter out the ions in the coolant.

[0089] The purification device 102 is a device used for purifying the coolant in the purification component 10. In this embodiment, the first end of the purification device 102 is connected to the second end of the conductivity sensor 101, the second end of the purification device 102 is connected to the second end of the filter component 20, and the controller 30 is connected to the purification device 102 and the conductivity sensor 101 respectively. When the conductivity of the coolant is relatively high, the purification device 102 can be used to purify the coolant detected by the conductivity sensor 101 to remove more ions in the coolant.

[0090] In this embodiment, the controller 30 can control the conductivity sensor 101 to measure the conductivity in the coolant and obtain the measured conductivity in real time, then compare the conductivity with a preset conductivity threshold, and control the purification device 102 to purify the coolant according to the comparison result. For example, if the comparison result indicates that the conductivity is too high, the purification device 102 can be controlled to purify the coolant, and if the comparison result indicates that the conductivity is moderate, the purification device 102 can be controlled to stop purifying the coolant.

[0091] In this embodiment, the purification component includes a conductivity sensor and a purification device. The first end of the conductivity sensor is connected to the liquid inlet, the first end of the purification device is connected to the second end of the conductivity sensor, the second end of the purification device is connected to the first end of the filtering component, and the controller is connected to the purification device and the conductivity sensor, respectively. The controller controls the conductivity sensor to measure the conductivity of the coolant, and can control the purification device to purify the coolant according to the conductivity, thereby realizing automatic purification of the coolant, and further using the coolant device can improve the flexibility of the coolant treatment method.

[0092] Based on the above embodiments, in one embodiment, Figure 3 As shown, the purification device 102 comprises:

[0093] The first solenoid valve 1021 has a first end connected to the second end of the conductivity sensor 101 .

[0094] The deionization resin tank 1022 has a first end connected to the second end of the first solenoid valve 1021 , and a second end connected to the first end of the filter assembly 20 .

[0095] The second solenoid valve 1024 , wherein the first end of the second solenoid valve 1024 is connected to the second end of the conductivity sensor 101 , and the second end of the second solenoid valve 1024 is connected to the first end of the filter assembly 20 .

[0096] The controller 30 is connected to the first solenoid valve 1021 and the second solenoid valve 1024 respectively. The controller 30 is specifically used to control the first solenoid valve 1021 to be turned on and the second solenoid valve 1024 to be turned off when the conductivity is higher than a preset conductivity threshold, so that the coolant enters the deionized resin tank 1022.

[0097] The deionizing resin tank 1022 is used to remove anions and cations in the coolant to purify the coolant.

[0098] Among them, the deionized resin tank 1022 is a device for removing anions and cations in the coolant. The deionized resin tank 1022 is filled with ion exchange resin. The ion exchange resin can selectively adsorb anions and cations in the coolant. For example, the cations in the resin (such as hydrogen ions) are exchanged with the cations in the coolant (such as calcium and magnesium ions), and the anions in the resin (such as hydroxide) are exchanged with the anions in the coolant (such as sulfate). Therefore, the anions and cations in the coolant can be removed by ion exchange technology. In this embodiment, the purification device 102 may include one or more deionized resin tanks 1022. For example, two deionized resin tanks 1022 can be set to improve the purification efficiency. Optionally, the deionized resin tank 1022 can also be replaced with an RO membrane or EDI equipment.

[0099] It can be understood that in order to save the use cost of the deionization resin tank 1022 and improve the efficiency of coolant treatment, the deionization resin tank 1022 can be used for purification treatment when the conductivity in the coolant is higher than the preset conductivity threshold, and the deionization resin tank 1022 can be stopped for purification treatment when the conductivity in the coolant is not higher than the preset conductivity threshold.

[0100] In this embodiment, a first solenoid valve 1021 and a second solenoid valve 1024 may be provided in the coolant treatment device, and the first solenoid valve 1021 is connected to the second end of the conductivity sensor 101, the first end of the second solenoid valve 1024 is connected to the second end of the conductivity sensor 101, and the first solenoid valve 1021 and the second solenoid valve 1024 are respectively connected to the controller 30. When the controller 30 detects that the conductivity measured by the conductivity sensor 101 is higher than a preset conductivity threshold, the first solenoid valve 1021 may be controlled to be turned on, and the second solenoid valve 1024 may be controlled to be turned off, so that the coolant can enter the deionized resin tank 1022, and then the coolant is purified by the deionized resin tank 1022. The preset conductivity threshold may be set according to the purification requirements of the coolant in the actual cooling operation.

[0101] It can be understood that if the controller 30 monitors that the conductivity measured by the conductivity sensor 101 is not higher than the preset conductivity threshold, the first solenoid valve 1021 is controlled to be closed, and the second solenoid valve 1024 is controlled to be turned on, so that the coolant cannot enter the ion resin tank, and the deionization resin tank 1022 is stopped from being used to purify the coolant.

[0102] Therefore, by setting the first solenoid valve 1021 and combining it with the measured conductivity, the coolant can be purified or stopped quickly and conveniently, thereby improving the flexibility of using the coolant treatment device for coolant treatment.

[0103] As a possible implementation, please continue to refer to Figure 3 The purification device 102 also includes a fine filter tube 1023, a first end of the fine filter tube 1023 is connected to the second end of the deionized resin tank 1022, and a second end of the fine filter tube 1023 is connected to the first end of the filter assembly 20; the fine filter tube 1023 is used to filter the coolant purified by the deionized resin tank 1022.

[0104] It is understandable that after the coolant is processed by the deionized resin tank 1022, the resin particles in the deionized resin tank 1022 may flow into the coolant processing device along with the coolant. Therefore, a fine filter tube 1023 may be provided after the deionized resin tank 1022 as a safety filter for the deionized resin tank 1022 to intercept the resin particles flowing out of the deionized resin tank 1022.

[0105] In this embodiment, the first end of the fine filter tube 1023 can be connected to the second end of the deionized resin tank 1022, and the second end of the fine filter tube 1023 can be connected to the first end of the filter assembly 20, so as to filter the coolant after purification by the deionized resin tank 1022, thereby intercepting the resin particles flowing out of the deionized resin tank 1022.

[0106] In this embodiment, the purification equipment includes a first solenoid valve, a deionization resin tank, and a second solenoid valve. The first end of the first solenoid valve is connected to the second end of the conductivity sensor, the first end of the deionization resin tank is connected to the second end of the first solenoid valve, the second end of the deionization resin tank is connected to the first end of the filter component, the first end of the second solenoid valve is connected to the second end of the conductivity sensor, and the second end of the second solenoid valve is connected to the first end of the filter component. A controller is connected to the first solenoid valve and the second solenoid valve. When the conductivity is higher than a preset conductivity threshold, the controller controls the first solenoid valve to be turned on and the second solenoid valve to be turned off, so that the coolant enters the deionization resin tank, so that the anions and cations in the coolant can be removed through the deionization resin tank, so as to avoid excessive concentration of anions and cations in the coolant, which affects the cooling effect, and realizes purification of the coolant.

[0107] Based on the above embodiments, in one embodiment, Figure 4 As shown, the filter assembly 20 comprises:

[0108] A turbidity detection device 201, wherein a first end of the turbidity detection device 201 is connected to a second end of the purification component 10;

[0110] The controller 30 is connected to the filtering device 202 and the turbidity detection device 201 respectively. The controller 30 is specifically used to control the turbidity detection device 201 to measure the turbidity value of the coolant, and control the filtering device 202 to filter the coolant according to the turbidity value.

[0111] Among them, the turbidity detection device 201 is a detection device for measuring the turbidity of the coolant, for example, it can measure the turbidity of suspended matter or dissolved matter in the coolant. Optionally, the turbidity detection device 201 can be a turbidity meter, a turbidity meter, a turbidity meter and other equipment. It can be understood that if the turbidity of the coolant is high, the suspended matter or sediment will hinder the flow of the coolant, increase the flow resistance, and thus reduce the operating efficiency of the cooling equipment; moreover, the high turbidity coolant will aggravate the corrosion and wear of the cooling equipment. Therefore, if the turbidity value of the coolant is relatively high, it is necessary to filter out the impurities in the coolant.

[0112] The filter device 202 is a device in the filter assembly 20 for filtering the coolant. In this embodiment, the first end of the filter device 202 is connected to the second end of the turbidity detection device 201, the second end of the filter device 202 is connected to the liquid outlet, and the controller 30 is connected to the filter device 202 and the turbidity detection device 201 respectively. When the turbidity value measured by the turbidity detection device 201 is relatively high, the filter device 202 can be controlled by the controller 30 to filter the coolant detected by the turbidity detection device 201 to remove impurities in the coolant.

[0113] In this embodiment, the controller 30 can control the turbidity detection device 201 to measure the content of impurities in the coolant, and obtain the measured turbidity value in real time, then compare the turbidity value with the preset turbidity value threshold, and control the filter device 202 to filter the coolant according to the comparison result. For example, if the comparison result indicates that the turbidity value is too high, the filter device 202 can be controlled to filter the coolant, and if the comparison result indicates that the turbidity value is moderate, the filter device 202 can be controlled to stop filtering the coolant.

[0114] In this embodiment, the filtering component includes a turbidity detection device and a filtering device. The first end of the turbidity detection device is connected to the second end of the purification component, the first end of the filtering device is connected to the second end of the turbidity detection device, the second end of the filtering device is connected to the liquid outlet, and the controller is connected to the filtering device and the turbidity detection device respectively. The controller controls the turbidity detection device to measure the turbidity value of the coolant, and can control the filtering device to filter the coolant according to the turbidity value, thereby realizing automatic filtering of the coolant, and further using the coolant device can improve the flexibility of the coolant treatment method.

[0115] Based on the above embodiments, in one embodiment, Figure 5 As shown, the filtering device 202 comprises:

[0116] A third solenoid valve 2021 , wherein a first end of the third solenoid valve 2021 is connected to a second end of the turbidity detection device 201 .

[0118] The fourth solenoid valve 2023 , the first end of the fourth solenoid valve 2023 is connected to the second end of the turbidity detection device 201 , and the second end of the fourth solenoid valve 2023 is connected to the liquid outlet.

[0119] The controller 30 is connected to the third solenoid valve 2021 and the fourth solenoid valve 2023 respectively. The controller 30 is specifically used to control the third solenoid valve 2021 to be turned on and the fourth solenoid valve 2023 to be turned off when the turbidity value is higher than the preset turbidity value threshold, so that the coolant enters the ultrafiltration tube 2022.

[0120] The ultrafiltration tube 2022 is used to filter bacteria in the coolant to filter the coolant.

[0121] Among them, the ultrafiltration tube 2022 is a device for removing macromolecular substances such as bacteria, proteins, colloids, etc. in the coolant. Compared with traditional filters, the ultrafiltration tube 2022 has higher filtering accuracy and can effectively remove harmful substances in the coolant to ensure the purity and transparency of the coolant. In order to save the use cost of the ultrafiltration tube 2022 and improve the efficiency of coolant treatment, the ultrafiltration tube 2022 can be used for filtering when the turbidity value of impurities in the coolant is higher than the preset turbidity threshold, and the ultrafiltration tube 2022 can be stopped for filtering when the turbidity value of impurities in the coolant is not higher than the preset turbidity threshold.

[0122] In this embodiment, a third solenoid valve 2021 may be provided in the coolant treatment device, a first end of the third solenoid valve 2021 may be connected to a second end of the turbidity detection device 201, a first end of the fourth solenoid valve 2023 may be connected to a second end of the turbidity detection device 201, and the third solenoid valve 2021 and the fourth solenoid valve 2023 may be connected to the controller 30, respectively. When the controller 30 detects that the turbidity value measured by the turbidity detection device 201 is higher than a preset turbidity value threshold, the third solenoid valve 2021 may be controlled to be turned on, and the fourth solenoid valve 2023 may be controlled to be turned off, so that the coolant enters the ultrafiltration tube 2022, and then the coolant is filtered through the ultrafiltration tube 2022. The preset turbidity value threshold may be set according to the filtering and processing requirements of the coolant in the actual cooling operation.

[0123] It can be understood that if the controller 30 monitors that the turbidity value measured by the turbidity detection equipment 201 is not higher than the preset turbidity value threshold, the third solenoid valve 2021 is controlled to be closed, and the fourth solenoid valve 2023 is controlled to be turned on, so that the coolant cannot enter the ultrafiltration tube 2022, and the ultrafiltration tube 2022 is stopped from filtering the coolant.

[0124] Therefore, by setting the third solenoid valve 2021 and combining it with the measured turbidity value, the cooling liquid can be filtered or stopped quickly and conveniently, thereby improving the flexibility of using the cooling liquid treatment device for cooling liquid treatment.

[0125] In this embodiment, the filtering device includes a third solenoid valve, an ultrafiltration tube, and a fourth solenoid valve.

The controller is connected to the third solenoid valve and the fourth solenoid valve, respectively. When the turbidity value is higher than the preset turbidity value threshold, the controller controls the third solenoid valve to be turned on and the fourth solenoid valve to be closed, so that the coolant enters the ultrafiltration tube, so that the bacteria in the coolant can be filtered through the ultrafiltration tube, the filtering accuracy is improved, and the filtering treatment of the coolant is realized.

[0128] The controller 30 is specifically used to control the sterilization component 40 to sterilize the coolant, and control the purification component 10 to purify the sterilized coolant.

[0129] The sterilization component 40 is a device for eliminating bacteria in the coolant to inhibit bacterial reproduction. In this embodiment, the first end of the sterilization component 40 can be connected to the liquid inlet to sterilize the liquid entering from the liquid inlet, and the second end of the sterilization component 40 can be connected to the first end of the purification component 10 to reduce bacteria in the coolant entering the deionized resin tank 1022 in the purification component 10, thereby improving the efficiency of the purification process.

[0130] In this embodiment, the sterilization component 40 is also connected to the controller 30, and the controller 30 can control the operation of the sterilization component 40 to sterilize the coolant. The coolant after sterilization can be input into the purification component 10, and the controller 30 can control the purification component 10 to purify the coolant after sterilization.

[0131] As a possible implementation, the controller 30 can control the purification component 10, the filtering component 20 and the sterilizing component 40 to process the coolant at the same time, or the controller 30 can also control the purification component 10 to purify the coolant and control the filtering component 20 and the sterilizing component 40 to stop processing the coolant, or the controller 30 can also control the filtering component 20 to filter the coolant and control the purification component 10 and the sterilizing component 40 to stop processing the coolant, or the controller 30 can also control the sterilizing component 40 to sterilize the coolant and control the purification component 10 and the filtering component 20 to stop processing the coolant. It can be understood that when the controller 30 controls the purification component 10, the filtering component 20 and the sterilizing component 40 to process the coolant at the same time, the coolant processing device can be used to simultaneously realize the purification, filtering and sterilization of the coolant, so that a variety of coolant processing technologies are integrated in the coolant processing device, thereby improving the flexibility of the coolant processing method.

[0132] In this embodiment, the coolant treatment device also includes a sterilization component, the first end of the sterilization component is connected to the liquid inlet, and the sterilization component is also connected to the controller. The controller can control the sterilization component to sterilize the coolant, and by connecting the second end of the sterilization component to the first end of the purification component, the purification component can be controlled to purify the coolant after sterilization, thereby sterilizing the coolant before the purification process, thereby improving the effect of the purification process.

[0133] In one embodiment, Figure 7 As shown, the sterilization assembly 40 comprises:

[0134] A fifth solenoid valve 401 , wherein a first end of the fifth solenoid valve 401 is connected to the liquid inlet, and a second end of the fifth solenoid valve 401 is connected to a first end of the purification component 10 .

[0135] The sixth solenoid valve 402 has a first end connected to the liquid inlet.

[0136] The sterilization lamp 403 has a first end connected to the second end of the sixth solenoid valve 402 , and a second end connected to the first end of the purification component 10 .

[0137] The controller 30 is connected to the fifth solenoid valve 401, the sixth solenoid valve 402 and the sterilization lamp 403 respectively. The controller 30 is specifically used to control the fifth solenoid valve 401 to be closed, the sixth solenoid valve 402 to be turned on, and the sterilization lamp 403 to be turned on to sterilize the coolant.

[0138] Among them, the sterilization lamp 403 is a device that uses ultraviolet radiation to kill bacteria, viruses and other microorganisms. For example, the sterilization lamp can be a UV sterilization lamp. In this embodiment, a fifth solenoid valve 401 can be set in the sterilization component 40, and the first end of the fifth solenoid valve 401 is connected to the liquid inlet, and the second end of the fifth solenoid valve 401 is connected to the purification component 10, and a sixth solenoid valve 402 is set, and the first end of the sixth solenoid valve 402 is connected to the liquid inlet, and the second end of the sixth solenoid valve 402 is connected to the first end of the sterilization lamp 403 included in the sterilization component 40. In this way, the fifth solenoid valve 401 can be controlled to be turned on or off by the controller 30, and the sixth solenoid valve 402 can be controlled to be turned on and off, so that the coolant input through the liquid inlet enters the purification component 10 or enters the sterilization component 40. Optionally, if the controller 30 controls the fifth solenoid valve 401 to be closed and controls the sixth solenoid valve 402 to be turned on, the coolant can be input into the sterilization component 40 from the liquid inlet, and the controller 30 can control the sterilization lamp 403 to turn on to sterilize the coolant.

[0139] As a possible implementation, if the controller 30 controls the fifth solenoid valve 401 to be turned on and controls the sixth solenoid valve 402 to be turned off, the coolant can be input from the liquid inlet to the purification component 10, and the controller 30 can control the purification component 10 to purify the coolant.

[0140] In this embodiment, the sterilization component includes a fifth solenoid valve, a sixth solenoid valve, and a sterilization lamp. The first end of the fifth solenoid valve is connected to the liquid inlet, the second end of the fifth solenoid valve is connected to the first end of the purification component, the first end of the sixth solenoid valve is connected to the liquid inlet, the first end of the sterilization lamp is connected to the second end of the sixth solenoid valve, and the second end of the sterilization lamp is connected to the first end of the purification component.

[0141] Based on the above embodiments, in one embodiment, Figure 8 As shown, the above-mentioned coolant treatment device also includes:

[0142] A circulation pump 50, wherein a first end of the circulation pump 50 is connected to the liquid inlet;

[0143] a seventh solenoid valve 60 , wherein a first end of the seventh solenoid valve 60 is connected to a second end of the circulation pump 50 ;

[0144] A first pressure sensor 70, wherein a first end of the first pressure sensor 70 is connected to a second end of the seventh solenoid valve 60, and a second end of the first pressure sensor 70 is connected to a first end of the purification component 10, and the first pressure sensor 70 is used to measure a first pressure value of the coolant entering from the liquid inlet;

[0145] A second pressure sensor 80, wherein a first end of the second pressure sensor 80 is connected to a second end of the filter assembly 20, and a second end of the second pressure sensor 80 is connected to the liquid outlet. The second pressure sensor 80 is used to measure a second pressure value of the coolant output by the purification assembly 10 and / or the coolant output by the filter assembly 20;

[0146] The controller 30 is also connected to the circulation pump 50, the seventh solenoid valve 60, the first pressure sensor 70 and the second pressure sensor 80 respectively. The controller 30 is also used to calculate the pressure difference between the first pressure value and the second pressure value, and when the pressure difference is less than a preset pressure difference threshold, control the circulation pump 50 to open, and increase the opening value of the seventh solenoid valve 60 to pump the coolant from the liquid inlet through the circulation pump 50, or, when the pressure difference is greater than or equal to the preset pressure difference threshold, control the circulation pump 50 to close, and reduce the opening value of the seventh solenoid valve 60 to stop pumping the coolant from the liquid inlet through the circulation pump 50.

[0147] The circulating pump 50 is a device for increasing the input power of the coolant input through the liquid inlet. The circulating pump 50 can increase the input amount of the coolant input from the liquid inlet. For example, the circulating pump 50 can be a variable frequency circulating water pump. It is understandable that in the process of purifying and / or filtering the coolant, if the flow rate of the coolant entering the purification component 10 or the filtering component 20 is small and cannot match the purification pressure difference of the purification component 10, or cannot match the filtering pressure difference of the filtering component 20, it is necessary to turn on the circulating pump 50 and adjust the opening value of the seventh solenoid valve 60 to the maximum value, so as to pump the coolant from the liquid inlet through the circulating pump 50 to increase the coolant in the coolant treatment device. In the process of pumping the coolant, the input amount of the input coolant is adjusted by the variable frequency function of the circulating pump 50. When the flow rate of the coolant increases to the adaptation value, or the coolant after purification and / or filtration meets the processing requirements, the circulation pump 50 can be turned off and the opening value of the seventh solenoid valve 60 can be reduced to reduce the input amount of the coolant.

[0148] In this embodiment, a first pressure sensor 70 and a second pressure sensor 80 may also be provided, wherein the first pressure sensor 70 may measure a first pressure value of the coolant entering from the liquid inlet, and the second pressure sensor 80 may measure a second pressure value of the coolant outputted by the purification component 10 and / or the filter component 20, so that the first pressure value and the second pressure value may be obtained by the controller 30, and the pressure difference between the first pressure value and the second pressure value may be calculated, and then the pressure difference may be compared with the preset pressure difference threshold, and it may be determined whether to control the circulation pump 50 to be turned on and whether to adjust the opening value of the seventh solenoid valve 60 according to the comparison result. Optionally, if the pressure difference is less than the preset pressure difference threshold, the circulation pump 50 is controlled to be turned on, and the opening value of the seventh solenoid valve 60 is increased, so that the circulation pump 50 pumps the coolant from the liquid inlet; or, if the pressure difference is greater than or equal to the pressure difference threshold, the circulation pump 50 is controlled to be turned off, and the opening value of the seventh solenoid valve 60 is reduced, so that the circulation pump 50 stops pumping the coolant from the liquid inlet.

[0149] In this embodiment, the coolant treatment device also includes a circulation pump, a seventh solenoid valve, a first pressure sensor and a second pressure sensor. The first end of the circulation pump is connected to the liquid inlet, the first end of the seventh solenoid valve is connected to the second end of the circulation pump, the first end of the first pressure sensor is connected to the second end of the seventh solenoid valve, the second end of the first pressure sensor is connected to the first end of the purification component, the first end of the second pressure sensor is connected to the second end of the filtration component, and the second end of the second pressure sensor is connected to the liquid outlet. The controller is also connected to the circulation pump, the seventh solenoid valve, the first pressure sensor and the second pressure sensor, respectively. The controller can determine the first The pressure difference between the pressure value and the second pressure value can, when the pressure difference is less than a preset pressure difference threshold, control the circulation pump to turn on and increase the opening value of the seventh solenoid valve to pump coolant from the liquid inlet through the circulation pump, and can, when the pressure difference is greater than or equal to the preset pressure difference threshold, control the circulation pump to turn off and reduce the opening value of the seventh solenoid valve to stop pumping coolant from the liquid inlet through the circulation pump, thereby automatically controlling the input amount of coolant in the coolant treatment device to meet the input amount of coolant for purification treatment and / or filtration treatment, thereby improving the efficiency of purification treatment and / or filtration treatment.
