The cold plate of a liquid-cooled server is a key component in the liquid-cooled server system, which is used to directly guide the liquid coolant to the heat source for efficient heat transfer and dissipation. During the production process of the cold plate of the liquid-cooled server, a series of strict tests are required to ensure its performance and quality.

[0003] Currently, the testing device can only perform single liquid drainage, drying, nitrogen filling or pressure maintaining tests, resulting in inconvenience and low efficiency in the testing process. And the testing device usually adopts a one-to-one configuration method, that is, one testing device can only correspond to one cold plate of the liquid-cooled server for testing. This configuration method limits the flexibility and scalability of the testing device.

[0025] To make the objectives, technical solutions, and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following descriptions, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0026] As Figures 1-3 shown, the present invention proposes a liquid drainage, drying, nitrogen filling, and pressure maintaining test equipment, including the main body 1 of the test equipment;

[0027] In this embodiment, an air pressure inlet 2 and a nitrogen inlet 3 are provided at the top of the main body 1 of the test equipment, and an air outlet end is provided at the bottom of the main body 1 of the test equipment.

[0028] In this embodiment, the air pressure inlet 2 is connected to an air pressure inlet heating system. The air pressure inlet heating system includes a first check valve, a first electromagnetic two-way valve, an air pressure heater, a first three-way ball valve, and an air compressor. The air compressor is connected to the first three-way ball valve, the first three-way ball valve is connected to the air pressure heater, the air pressure heater is connected to the first electromagnetic two-way valve, the first electromagnetic two-way valve is connected to the first check valve, and the first check valve is connected to the air pressure inlet 2.

[0029] In this embodiment, the nitrogen inlet 3 is connected to a nitrogen inlet system. The nitrogen inlet system includes a second check valve, a second electromagnetic two-way valve, and a nitrogen generator. The nitrogen generator is connected to the second electromagnetic two-way valve, the second electromagnetic two-way valve is connected to the second check valve, and the second check valve is connected to the air pressure inlet 2.

[0030] In this embodiment, the air outlet is connected to the liquid drainage system. The liquid drainage system includes a second three-way ball valve, a third three-way ball valve, a negative pressure gauge, a sensor pipeline, a humidity and temperature sensor, and a third electromagnetic two-way valve. The third electromagnetic two-way valve is connected to the sensor pipeline. The humidity and temperature sensor is installed on the inner wall of the sensor pipeline. The sensor pipeline is connected to the third three-way ball valve. The third three-way ball valve is respectively connected to the second three-way ball valve and the negative pressure gauge. The second three-way ball valve is connected to the air outlet at the bottom of the test equipment body 1, and the second three-way ball valve is connected to the first three-way ball valve.

[0031] It should be noted that: The product is placed into the test equipment body 1, and then air is sent into the test equipment body 1 through an air compressor in sequence through a first three-way ball valve, an air compressor heater, a first solenoid two-way valve, and a first check valve. The liquid inside the cold plate is dried by high-pressure gas. When the gas passes through the air compressor heater, the pure water in the product cavity is blown out. At the same time, the air enters the second three-way ball valve through the first three-way ball valve to drive the second three-way ball valve to open the air outlet end, ensuring the smooth discharge of the liquid. During this process, the liquid discharge time can be set, and the current setting is 60 seconds. To prevent gas backflow, a first check valve is added to the air inlet end to ensure that the gas only enters and does not exit. This step effectively removes the liquid inside the cold plate and provides a clean environment for subsequent operations. After the liquid discharge is completed, the equipment enters the drying stage. The air compressor heater starts and heats up to the specified temperature to start the drying process. The third three-way ball valve opens the sensor pipeline, and the drying parameters are detected in real time through a humidity-temperature sensor. The drying process is divided into three stages: start drying, drying process, and drying end; in the start drying stage, the humidity is detected to ensure the correct connection of the cold plate and prevent the situation of not connected or wrongly connected. The drying process continues until the humidity detected continuously for 10 times is less than 10%, indicating that the drying is qualified. After the drying end, the high-temperature and high-pressure gas supply is stopped, and the humidity is continuously detected to be less than 10% for 3 times to ensure thorough drying. The drying process not only removes the residual moisture but also ensures the drying effect through temperature control, providing a dry environment for the subsequent nitrogen filling process; after the drying is completed, the equipment enters the nitrogen filling stage. First, the air in the product cavity is discharged by opening the third solenoid two-way valve. The nitrogen filling process is divided into three stages: evacuating pressure, injecting nitrogen pressure, and maintaining pressure. In the evacuating pressure stage, nitrogen is injected into the test equipment body 1 through a nitrogen generator to discharge the air inside the cold plate and ensure that there is no residual air in the cavity. Then, in the injecting nitrogen pressure stage, the air outlet end is closed and nitrogen is continuously injected to make the pressure in the cavity reach the set standard range ([200, 220) KPa) and maintain for a certain time to ensure sufficient nitrogen filling. Finally, in the maintaining pressure stage, the air inlet end is closed and maintained for a certain time to test whether the deviation of the pressure value is within the allowable range (injecting nitrogen pressure ± 3%). The nitrogen filling process not only provides nitrogen protection for the product but also ensures the accuracy and stability of nitrogen filling through pressure control. This structure can complete all necessary test steps of liquid discharge drying, nitrogen filling, and pressure holding at one time without replacing or connecting multiple devices, thus significantly improving the test efficiency.

[0032] In a specific embodiment, the third solenoid two-way valve is connected to a silencer. The silencer provided can play a role in noise reduction.

[0033] In a specific embodiment, the test equipment body 1 is connected to an early warning system, which is used to display the operating status of the current test equipment body 1, enabling the operator to handle equipment abnormalities in a timely and effective manner. The early warning system includes a cloud, an early warning module, a data acquisition module, and a data analysis module; the data acquisition module is used to collect various data during the cold plate test. The data acquisition module is connected to the cloud and transmits the collected data to the cloud. The data analysis module is connected to the data acquisition module and is used to analyze the various index data collected by the data acquisition module. The data analysis module is connected to the cloud and transmits the analyzed data to the cloud. The cloud is connected to the early warning module, and the cloud manages the analyzed data. Once an abnormality is detected, an abnormal signal is transmitted to the early warning module, and an alarm is issued through the early warning module.

[0034] It should be noted that: through the set early warning system, the operating status of the equipment can be monitored in real time. Once any abnormality or parameter deviating from the normal operating range is detected, the system will immediately issue an alarm. Detecting faults in a timely manner can reduce the risk of equipment damage and avoid possible downtime; the operator can quickly understand the abnormal status of the equipment through the early warning system and immediately take necessary measures. This rapid response ability can minimize the production interruption time and ensure the continuity and stability of the production process.
