Description

Technical Field

[0001] This invention relates to the field of heat dissipation equipment technology, and more specifically, to a system and method for online monitoring and maintenance of filters. Background Technology

[0002] With the advancement of information technology, artificial intelligence has become an indispensable part of social development, and data centers, as its physical carriers, play a crucial role. The Cooling Distribution Unit (CDU), as the cooling distribution unit of the data center, plays a vital role in the normal operation of the data center. Currently, the anomaly detection of the data center CDU system is crucial for the normal operation of the entire data center. Traditional CDUs have redundant water pump designs, with one pump connected to a set of piping and filters, such as... Figure 1 As shown. The filter can filter impurities during the operation of the secondary water circuit. The filter is equipped with butterfly valves or other valves at both ends. The function of the valves is to cut off the water circuit and replace the filter screen when the filter needs maintenance.

[0003] However, the monitoring and maintenance of traditional CDU internal filters have the following problems:

[0004] 1. The filter status cannot be monitored online, making it difficult to accurately determine the blockage status of impurities in the water circuit;

[0005] 2. During filter maintenance, manual operation of valves is required to replace the filter screen; someone must be on duty.

[0006] 3. The dual-redundant design of the water pump is designed to maintain the filter. The two water circuits are independent, which cannot make good use of the water pump resources. Summary of the Invention

[0007] To address the shortcomings of existing technologies, the present invention aims to provide a system and method for online monitoring and maintenance of filters, thereby improving the reliability of liquid cooling systems by adding pressure monitoring at both ends of the filter and online maintenance measures.

[0008] To solve the above problems, the technical solution of the present invention is as follows:

[0009] A system for online monitoring and maintenance of a filter includes a filter, a monitoring system, and a control system. The monitoring system includes pressure sensors installed at both ends of the filter to collect pressure data on both sides. Under normal operating conditions, the pressure sensors at both ends will detect a value. The control system monitors the filter's status based on the change in the pressure difference between the two sides of the filter. If the pressure difference detected by the pressure sensors is normal, monitoring continues; if the pressure difference detected by the pressure sensors is abnormal, the control system controls a three-way solenoid valve to switch the water path, thereby achieving online monitoring and maintenance of the filter's status.

[0010] Preferably, the three-way solenoid valve is a one-inlet, two-outlet type, with the two outlets corresponding to two filter pipelines respectively. When the control system determines that the filter is clogged and needs maintenance, it controls the opening and closing of the three-way solenoid valve to switch to another water path.

[0011] Preferably, both water pumps output water to the same circulation pipeline, and the two water pumps can work simultaneously or one pump can work at a time.

[0012] Furthermore, the present invention also provides a method for online monitoring and maintenance of a filter, comprising the following steps:

[0013] Pressure data at both ends of the filter is collected in real time using a pressure sensor;

[0014] The collected pressure data from both ends of the filter is transmitted to the control system, which monitors the filter's status based on the change in the pressure difference between the two ends of the filter.

[0015] If the data is normal, continue monitoring; if the data is abnormal, control the three-way solenoid valve to switch the water path.

[0016] Prior to this, the step of transmitting the collected pressure data from both ends of the filter to the control system, and the control system monitoring the filter status based on the change in the difference between the pressure data from both ends of the filter, specifically includes: if the filter becomes clogged, the readings of the pressure sensors at both ends will change, and the control system monitoring the filter status based on the change in the difference between the pressure readings on both sides of the filter.

[0017] Prior to this, in the step of continuing monitoring if the data is normal and controlling the three-way solenoid valve to switch the water path if the data is abnormal, the three-way solenoid valve is a one-inlet, two-outlet type, with the two outlets corresponding to two filter pipelines respectively. When the control system determines that the filter is clogged and needs maintenance, it controls the opening and closing of the three-way solenoid valve to switch to another water path, thereby realizing the function of online maintenance of the filter water path.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. Improve the reliability of the liquid cooling system by adding pressure monitoring at both ends of the filter and implementing online maintenance measures.

[0020] 2. Reduce operation and maintenance costs and improve the visibility of liquid cooling system components.

[0021] 3. The water pump is more flexible in operation and maintenance, and has a wider range of flow rate applications. Attached Figure Description

[0028] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0029] Specifically, this invention provides a system for online monitoring and maintenance of filters, which can monitor the filter status online and maintain water circuit switching online, such as... Figure 2 and Figure 3 As shown, the system includes a filter, a monitoring system, and a control system. The monitoring system includes pressure sensors installed at both ends of the filter to collect the pressure on both sides of the filter. Under normal filter operation, the pressure sensors at both ends will monitor a value. If the filter becomes clogged, the pressure sensor readings will change, and the pressure sensor data will be transmitted back to the control system in real time. The control system monitors the filter's status based on the change in the pressure difference data on both sides of the filter, thereby achieving online monitoring of the filter's status.

[0030] If the pressure difference detected by the pressure sensor is normal, monitoring continues; if the pressure difference detected by the pressure sensor is abnormal, the control system controls the three-way solenoid valve to switch the water path, specifically as follows: Figure 3 As shown, water from two water pumps flows to a three-way solenoid valve. This valve is a one-inlet, two-outlet type, with each outlet corresponding to a different filter pipeline. When the control system determines that the filter is clogged and requires maintenance, it controls the opening and closing of the three-way solenoid valve to switch to another water path, thus realizing the function of online maintenance of the filter water path.

[0031] In addition, the present invention optimizes the water circuit, with two water pumps outputting water to the same circulation pipeline. Compared with the traditional technical solution where one water pump corresponds to one circulation pipeline and only one water pump works during operation, the present invention allows two water pumps to work simultaneously or individually, making it more adaptable to different scenarios and unaffected by filter maintenance time, allowing for easy switching at any time.

[0032] Furthermore, the present invention also provides a method for online monitoring and maintenance of filters, such as... Figure 4 and Figure 5 As shown, the method includes the following steps:

[0033] S1: Real-time pressure data at both ends of the filter is collected via a pressure sensor;

[0034] Specifically, a pressure sensor is installed at both ends of the filter to collect pressure data at both ends of the filter in real time.

[0035] S2: The collected pressure data at both ends of the filter is transmitted to the control system, which monitors the status of the filter based on the change in the difference between the pressure data at both ends of the filter.

[0036] Specifically, if the filter becomes clogged, the pressure sensor readings at both ends will change, and the control system can monitor the filter's status based on the change in the difference between the pressure readings on both sides of the filter.

[0037] S3: If the data is normal, continue monitoring; if the data is abnormal, control the three-way solenoid valve to switch the water path.

[0038] Specifically, if the pressure difference detected by the pressure sensor is normal, monitoring continues; if the pressure difference detected by the pressure sensor is abnormal, the three-way solenoid valve is controlled to switch the water path. The three-way solenoid valve is a one-inlet, two-outlet type, with the two outlets corresponding to two filter pipelines respectively. When the control system determines that the filter is clogged and needs maintenance, it controls the opening and closing of the three-way solenoid valve to switch to another water path, thereby realizing the function of online maintenance of the filter water path.

[0039] Specific embodiments of the present invention have been described above. It should be understood that the present invention is not limited to the specific embodiments described above, and those skilled in the art can make various changes or modifications within the scope of the claims, which do not affect the essence of the present invention. Unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.
