[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 conjunction with the specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, 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 server pressure-holding test device, including the main body 1 of the test device;

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

[0028] In this embodiment, the air compressor air inlet 2 is connected to an air compressor air inlet heating system. The air compressor air inlet heating system includes a first check valve, a first electromagnetic two-way valve, an air compressor 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 compressor heater, the air compressor 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 compressor air 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 compressor air 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: put the product into the test equipment body 1, and then use the air compressor to guide the air through the No. 1 three-way ball valve, air compressor heater, No. 1 electromagnetic two-way valve and No. 1 check valve to the test equipment body 1, and use the high-pressure gas to blow the liquid inside the cold plate dry. 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 passes through the No. 1 three-way ball valve and enters the No. 2 three-way ball valve to drive the No. 2 three-way ball valve to open the outlet end to ensure that the liquid is discharged smoothly. In this process, the drainage time can be set, and the current setting is 60 seconds. In order to prevent gas reflux, a No. 1 check valve is added to the air inlet end to ensure that the gas The liquid only goes in but not out. This step effectively removes the liquid inside the cold plate and provides a clean environment for subsequent operations. After the drainage is completed, the equipment enters the drying stage. The air compressor heater starts and heats to the specified temperature to start the drying process. The No. 3 three-way ball valve opens the sensor pipeline and the drying parameters are detected in real time through the wet temperature sensor. The drying process is divided into three stages: start drying, drying process and end of drying. In the start drying stage, the humidity is detected to ensure that the cold plate is correctly connected and prevent the situation of no connection or wrong connection. The drying process continues until the humidity detected for 10 consecutive times is less than 10%, indicating that the drying meets the standard. After the completion, stop introducing high-temperature and high-pressure gas, and continuously detect the humidity for 3 times to be less than 10% to ensure thorough drying. The drying process not only removes 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 No. 3 electromagnetic two-way valve. The nitrogen filling process is divided into three stages: emptying pressure, nitrogen injection pressure and maintaining pressure. In the emptying pressure stage, nitrogen is injected into the test equipment body 1 through a nitrogen generator to discharge the air in the cold plate to ensure that there is no residual air in the cavity. Then, in the nitrogen injection pressure In the first stage, the air outlet is closed and nitrogen is continuously injected to make the pressure in the cavity reach the set standard range ([200, 220) KPa) and maintain it for a certain period of time to ensure that the nitrogen is fully filled. Finally, in the pressure maintaining stage, the air inlet is closed and maintained for a certain period of time to test whether the pressure value deviation is within the allowable range (nitrogen injection 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 drainage drying, nitrogen filling and pressure maintenance at one time without replacing or connecting multiple devices, thereby significantly improving the test efficiency.

[0032] In a specific embodiment, the No. 3 electromagnetic two-way valve is connected to a muffler, which can reduce noise.

[0033] In a specific embodiment, the test equipment body 1 is connected to an early warning system, which is used to display the operating state 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 state 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; operators can quickly understand the abnormal state of the equipment through the early warning system and immediately take necessary measures. This rapid response ability can minimize the time of production interruption and ensure the continuity and stability of the production process.

[0035] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
