Description

Technical Field

[0001] This utility model relates to the field of electronic equipment cleaning technology, and in particular to a cleaning device for immersion liquid-cooled servers. Background Technology

[0002] A single-phase immersion liquid-cooled server is a heat dissipation system that completely immerses the server hardware in a non-conductive coolant. The coolant remains in a liquid state at all times, absorbing and transferring heat to achieve efficient heat dissipation, reduce energy consumption, and extend equipment life. By completely immersing the server hardware in a non-conductive coolant, the high thermal conductivity of the liquid enables efficient heat dissipation and energy saving.

[0003] Currently, the most common cleaning technology for single-phase immersion liquid-cooled servers involves removing the entire server from the coolant and treating the coolant using traditional methods such as ultrasonic cleaning, filtration, or simple chemical cleaning. However, most of these cleaning methods have the following problems:

[0004] Incomplete cleaning: For some oil stains that are in close contact with electronic components and are firmly attached, as well as special organic metabolites produced by electronic components during long-term operation, ultrasonic cleaning and ordinary filtration methods are difficult to completely remove them in single-phase synthetic oil coolant. This may result in the heat dissipation effect and the reliability of electronic components still being affected after cleaning.

[0005] Cleaning agents are costly and can cause environmental pollution: When using chemical cleaning agents, it is often impossible to accurately control the amount and composition of the cleaning agent, which can easily lead to overuse of the cleaning agent. This not only increases the cleaning cost, but may also cause environmental pollution due to cleaning agent residue. In addition, some cleaning agents have poor compatibility with single-phase synthetic oil coolants, which may affect the performance of the coolant.

[0006] Ineffective recycling of cleaning agents: Cleaning agents used for cleaning usually require large-scale discharge or complex treatment before they can be reused, resulting in resource waste and increased processing costs.

[0007] Therefore, this utility model proposes an immersion liquid-cooled server cleaning device to solve the problems existing in the prior art. Utility Model Content

[0008] To address the aforementioned problems, the purpose of this invention is to propose an immersion liquid-cooled server cleaning device that solves the issues of incomplete cleaning, high cost of cleaning agents that easily cause environmental pollution, and the inability to effectively recycle and reuse cleaning agents.

[0009] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: an immersion liquid-cooled server cleaning device, including a cleaning tank, an ultrasonic cleaning component fixed on the inner side wall of the cleaning tank, a PLC controller fixed on the outer side wall of the cleaning tank, a cleaning agent adding pipe, a cleaning fluid injection pipe and a cleaning fluid discharging pipe connected to the side wall of the cleaning tank away from the ultrasonic cleaning component, a cleaning agent adding system connected to the end of the cleaning agent adding pipe away from the cleaning tank, and a cleaning fluid circulation system connected between the cleaning fluid injection pipe and the cleaning fluid discharging pipe.

[0010] A further improvement is that the cleaning agent addition system includes a heater and a precision metering pump, the heater and the cleaning agent addition pipe are connected, and the precision metering pump is connected to the heater through a cleaning agent input pipe.

[0011] A further improvement is that the precision metering pump is connected to an external cleaning agent storage device, and a first temperature sensor electrically connected to the heater is installed on the cleaning agent input pipe.

[0012] A further improvement is that the cleaning fluid circulation system includes a filter, a cleaning agent recovery device, a cleaning fluid storage tank, and a circulation pump connected in sequence between the cleaning fluid injection pipe and the cleaning fluid discharge pipe, wherein the cleaning fluid storage tank stores the cleaning fluid.

[0013] A further improvement is that the filter is connected to the cleaning fluid discharge pipe, and the circulation pump is connected to the cleaning fluid injection pipe.

[0014] A further improvement is that the filter and the cleaning agent recovery device are connected through a first circulation pipe, the cleaning agent recovery device and the cleaning fluid storage tank are connected through a second circulation pipe, and the cleaning fluid storage tank and the circulation pump are connected through a third circulation pipe.

[0015] A further improvement is that a flow sensor and a second temperature sensor are installed on the cleaning fluid injection pipe, and both the flow sensor and the second temperature sensor are electrically connected to the PLC controller.

[0016] The beneficial effects of this utility model are as follows: This utility model includes a cleaning tank that combines three cleaning technologies: ultrasonic cleaning, circulating filtration, and chemical cleaning. It can comprehensively and effectively remove dust, impurities, oil stains, and special organic metabolites generated by electronic components from single-phase immersion liquid-cooled servers, greatly improving the server's heat dissipation performance and the reliability of electronic components, extending the server's service life, and efficiently recycling the cleaning fluid, reducing the amount of cleaning fluid used and the frequency of replacement, significantly reducing the server's maintenance costs. At the same time, it reduces the amount of cleaning agent emitted, reducing the risk of environmental pollution, and meeting the requirements of environmental protection and sustainable development. In addition, the automated operation of the entire cleaning process reduces manual intervention, improves cleaning efficiency and operational safety, and reduces the risk caused by human error.

Detailed Implementation

[0019] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0020] according to Figure 1As shown, this embodiment provides an immersion liquid-cooled server cleaning device, including a cleaning tank 1 for accommodating the immersion liquid-cooled server to be cleaned and an ultrasonic cleaning assembly 2 fixed to the inner wall of the cleaning tank 1. The cleaning tank 1 is made of a corrosion-resistant material compatible with single-phase synthetic oil coolant and cleaning agents, ensuring that it will not chemically react with the cleaning fluid during the cleaning process, affecting the cleaning effect and equipment safety. The ultrasonic cleaning assembly 2 can generate ultrasonic waves of specific frequency and intensity, causing the cleaning fluid to produce a cavitation effect under the action of ultrasonic waves, enhancing the cleaning effect on contaminants on the surface and in the gaps of electronic components. Especially for oil stains and metabolites that are difficult to remove using traditional filtration and circulation methods, ultrasonic cleaning can play a very good auxiliary cleaning role. The outer wall of the cleaning tank 1 is fixed with a device for controlling the cleaning process. The PLC controller 3 sets the operating parameters. The PLC controller 3 presets different cleaning programs and automatically controls parameters such as the flow rate of the cleaning fluid circulation system, the amount of cleaning agent added, the ultrasonic power, and the cleaning time according to parameters such as the degree of contamination of the server and the type of coolant, so as to realize the automated cleaning process. The side wall of the cleaning tank 1 away from the ultrasonic cleaning component 2 is connected to a cleaning agent adding pipe 4 for injecting cleaning agent into the cleaning tank 1, a cleaning fluid injecting pipe 5 for injecting cleaning liquid into the cleaning tank 1, and a cleaning fluid discharging pipe 6 for discharging the cleaning liquid in the cleaning tank 1. The end of the cleaning agent adding pipe 4 away from the cleaning tank 1 is connected to a cleaning agent adding system for supplying cleaning agent to the cleaning tank 1. A cleaning fluid circulation system for recycling the cleaning liquid is connected between the cleaning fluid injecting pipe 5 and the cleaning fluid discharging pipe 6.

[0021] The cleaning agent addition system consists of a heater 7 and a precision metering pump 8. The heater 7 is connected to the end of the cleaning agent addition pipe 4 away from the cleaning tank 1. A cleaning agent input pipe 9 is connected between the precision metering pump 8 and the heater 7. The heater 7 can heat the cleaning agent to a suitable temperature range, thereby improving cleaning efficiency and reducing cleaning time.

[0022] The precision metering pump 8 is connected to an external cleaning agent storage device. According to the degree of contamination and cleaning needs, the precision metering pump 8 adds an appropriate amount of cleaning agent from the external cleaning agent storage device to the cleaning tank 1 and into the cleaning liquid circulation system. A first temperature sensor 10, which is electrically connected to the heater 7, is installed on the cleaning agent input pipe 9 to monitor the temperature of the injected cleaning agent in real time.

[0023] The cleaning fluid circulation system consists of a filter 11, a cleaning agent recovery device 12, a cleaning fluid storage tank 13, and a circulation pump 14, which are connected sequentially between the cleaning fluid injection pipe 5 and the cleaning fluid discharge pipe 6. The cleaning fluid storage tank 13 is used to store the cleaning fluid. The circulation pump 14 is responsible for transporting the cleaning fluid from the cleaning fluid storage tank 13 to the cleaning tank 1 and circulating the cleaning fluid between the cleaning tank 1 and the filter 11 to continuously remove contaminants. The filter 11 adopts a multi-stage filtration structure, which can effectively filter out contaminants of different particle sizes such as dust, impurities, oil, and metabolites. The cleaning agent recovery device 12 uses specific separation technology (membrane separation or adsorption separation) to recover reusable cleaning fluid components from the used cleaning fluid. The recovered cleaning fluid can be returned to the cleaning fluid storage tank 13 for reuse, reducing the amount of cleaning fluid used and discharged.

[0024] The filter 11 is connected to the end of the cleaning fluid discharge pipe 6 away from the cleaning tank 1, and is used to introduce the cleaning fluid in the cleaning tank 1 into the filter 11 for filtration. The circulation pump 14 is connected to the end of the cleaning fluid injection pipe 5 away from the cleaning tank 1, and is used to introduce the cleaning fluid from the cleaning fluid storage tank 13 into the cleaning tank 1.

[0025] A first circulation pipe 15 is connected between the filter 11 and the cleaning agent recovery device 12 for introducing the filtered cleaning liquid into the cleaning agent recovery device 12. A second circulation pipe 16 is connected between the cleaning agent recovery device 12 and the cleaning liquid storage tank 13 for introducing the recovered cleaning liquid into the cleaning liquid storage tank 13. A third circulation pipe 17 is connected between the cleaning liquid storage tank 13 and the circulation pump 14 so as to pump the cleaning liquid in the cleaning liquid storage tank 13 into the cleaning tank 1.

[0026] The cleaning fluid injection pipe 5 is equipped with a flow sensor 18 for real-time monitoring of the flow rate of the cleaning fluid in the pipe and a second temperature sensor 19 for real-time monitoring of the temperature of the cleaning fluid in the pipe. Both the flow sensor 18 and the second temperature sensor 19 are electrically connected to the PLC controller 3 to transmit the monitored data back to the PLC controller 3 for display.

[0027] In actual use, the immersion liquid-cooled server cleaning device is pre-filled with cleaning fluid in the cleaning tank 1. The immersion liquid-cooled server to be cleaned is placed in the cleaning tank 1 to ensure that the immersion liquid-cooled server is completely submerged in the cleaning fluid. According to the usage time and degree of contamination of the immersion liquid-cooled server, the corresponding cleaning program is started by the PLC controller 3. The cleaning fluid circulation system starts to work. The circulation pump 14 delivers the cleaning fluid in the cleaning fluid storage tank 13 to the cleaning tank 1 through the cleaning fluid injection pipe 5, and circulates between the cleaning tank 1 and the filter 11.

[0028] Meanwhile, the cleaning agent addition system adds the cleaning agent into the cleaning tank 1 through the precision metering pump 8 according to the preset addition amount and ratio. During the cleaning agent addition process, the first temperature sensor 10 monitors the temperature of the cleaning agent and the heater 7 heats the cleaning agent to the preset temperature. During cleaning, the ultrasonic cleaning component 2 starts to work according to the set power and frequency, generating ultrasonic waves to clean the electronic components of the immersed liquid-cooled server. During the cleaning process, the flow sensor 18 and the second temperature sensor 19 monitor the temperature and flow of the cleaning liquid in the pipeline in real time, and transmit the sensor signals to the PLC controller 3 for display.

[0029] During the cleaning process, filter 11 continuously filters out contaminants from the cleaning fluid. After the cleaning fluid carrying contaminants passes through filter 11, the clean cleaning fluid returns to cleaning tank 1, forming a closed-loop cleaning cycle system. After cleaning for a certain period of time, PLC controller 3 stops the cleaning process according to a preset program. At this time, the cleaning fluid circulation system stops running. The cleaned cleaning fluid is transported through pipeline to cleaning agent recovery equipment 12 for cleaning agent recovery. The recovered cleaning fluid is returned to cleaning fluid storage tank 13 and can be reused in the next round of cleaning. The remaining waste liquid is discharged through a special waste liquid treatment pipeline for subsequent centralized treatment or recycling.
