[0002] Currently, liquid cooling technology faces numerous challenges, including factors such as temperature, vibration, dust, and humidity. These factors bring new changes to liquid cooling design and delivery, necessitate multi-indicator evaluation in the selection of heat transfer fluids, and impose stricter requirements on material compatibility. To ensure the professional advantages of the data center testing service platform's technical services, the supplier customizes liquid cooling dummy load products that can meet the different operating conditions of the simulated liquid cooling system, based on the provided technical requirements for liquid cooling testing dummy loads.

Adhering to the principles of green development, it aims to improve data center energy efficiency and reduce PUE, reflecting the data center development trend. This will enhance the utilization efficiency and stability of servers through improved high-efficiency cooling, allowing for more servers to be deployed within a given data center space. It will also improve computing efficiency. Summary of the Invention

[0019] Example:

[0020] like Figures 1-3 As shown, a liquid-cooled dummy load testing device includes a frame 17 with an upper plate and a lower plate. A residual current device (RCD) 1 is installed on the upper plate of the frame 17. The RCD 1 is mainly used to protect against electrical leakage faults in the equipment and to protect against fatal electric shocks. It has overload and short-circuit protection functions and can be used to protect the line or load from overload and short circuit. A multi-functional display screen 2 is installed on the upper plate of the frame 17 and is located to the side of the RCD 1. The multi-functional display screen 2 can display voltage, current, power, inlet and outlet temperatures, pressure, and flow rate in real time, intuitively presenting the equipment's operating status. The inlet and outlet temperature, pressure, and flow rate thresholds are automatically displayed. The system includes customizable settings, support for data curve display, historical data storage, recording of equipment operation history, one-click USB flash drive export of saved data, and USB flash drive data name with a unique identifier for each device for easy data backup and analysis. It also features real-time display of faults. Two first handling handles 3 are fixedly installed on either side of the upper plate of the frame 17 for equipment handling. An air circuit breaker 4 is installed on the upper plate of the frame 17, located below the residual current device 1. The air circuit breaker 4 is a switch that automatically disconnects when the current in the circuit exceeds the rated current. In addition to contacting and disconnecting circuits, it also protects against short circuits, severe overloads, and undervoltage in circuits or electrical equipment. The device is flexible in adjustment, allowing for power adjustment within the 1-30kW range, resulting in more accurate measurements. A buzzer 5 is mounted on the upper panel of frame 17; it flashes intermittently and sounds an alarm when a load failure occurs. There are three aviation plug power interfaces 6, designated A, B, and C, mounted on the upper panel of frame 17. These interfaces power the device; each is a separate phase with one interface per circuit, with circuit A supplying power to the secondary circuit. A power indicator light 7 is mounted on the upper panel of frame 17; the green indicator light illuminates when circuit A is powered. A USB interface 8 is located on the upper panel of frame 17 and is used for exporting historical data. The exported data name corresponds to the device number, facilitating data backup and analysis.

[0021] like Figure 3 As shown, the four casters 9 on the lower plate of frame 17 are used for equipment handling, reducing the burden on personnel. This allows for easy load handling by hand, resulting in short deployment time and convenience. A flow regulating valve 10 is installed on the lower plate of frame 17. This valve is an intuitive and simple flow regulation control device. During testing, the flow regulating valve 10 is used to set the flow rate. Under the action of water, the valve automatically eliminates flow deviations caused by residual pressure head and pressure fluctuations in the pipeline, maintaining the set flow rate regardless of system pressure changes. There are two balancing valves 11: one located above the inlet pipe and the other above the outlet pipe. When the balancing valve is working normally, the piston inside the valve automatically adjusts according to the pipeline flow rate, balancing the flow between branch pipes. However, manual adjustment is sometimes necessary. For example, if there are impurities inside the valve, it may affect automatic adjustment. In this case, the flow can be balanced by manually adjusting the small nozzle. To manually adjust the balancing valve, first open both valve nozzles, then adjust the inlet and outlet nozzles as needed. Manually rotating the valve nozzles changes the pipeline flow rate to achieve flow balance. After adjustment, simply close the two small nozzles; it can also be used to collect water samples.

[0022] like Figure 3 As shown, the stainless steel automatic air vent valve 12 is installed on the equipment pipeline and is used to remove air from the pipeline system; the liquid inlet 13 is located at the pipeline inlet, the pipe diameter of the liquid inlet 13 is DN25, and the chuck is 50.5mm; the second handling handle 14 is installed on the lower plate of the frame 17 and is used for equipment handling; the drain valve 15 is installed on the equipment pipeline and is used for equipment depressurization and drainage. After the equipment is stopped, it is used to fill the pipeline with nitrogen; the liquid outlet 16 is located at the pipeline outlet, the pipe diameter of the liquid outlet 16 is DN25, and the chuck is 50.5mm.

[0023] Working Principle: When the equipment is in operation, first, place the load inside the cabinet. Connect the equipment's inlet 13 and outlet 16 to the tested cooling system via red and blue EPDM tubing, ensuring all air is purged and there are no liquid leaks. Then, before connecting the power connector 6 (aviation plug), confirm all circuit breakers are in the open position. After confirming this, connect and power on connector A. Once the power indicator 7 illuminates and the buzzer 5 does not alarm, connect and power on connectors B and C. Set the upper limits for inlet and outlet temperature, pressure, and flow rate. The maximum upper limit for inlet and outlet temperature must not exceed 75℃, and the maximum upper limit for pressure must not exceed 1.0MPa. Turn on and run the cold source and water pump of the tested system, confirming that the equipment's inlet and outlet flow rate, temperature, pressure, and power are normal. If an alarm occurs during operation, promptly investigate the cause of the fault.

[0024] When adjusting the load, first close the leakage current device (RCD), then apply the load according to the test environment. When the load is de-energized, first disconnect the load in the appropriate range, then disconnect the RCD. It supports data curve display, historical data storage, recording of equipment operation history, and one-click USB data export. Exported data is named with a unique identifier for each device for easy data backup and analysis. It also supports one-click historical data clearing. After the equipment is shut down, disconnect the EPDM piping. If the equipment is not used for an extended period, flush it with high-purity water, then purge with nitrogen, dry, and seal with nitrogen pressure at 0.1 MPa.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
