Description

Technical Field

[0001] This invention relates to the field of cooling water circulation machine performance testing technology, specifically to a dynamic control device for multiple parameters of circulating fluid. Background Technology

[0002] Cooling water circulators are widely used in laser equipment, medical devices, semiconductor manufacturing, and laboratory instruments. Their function is to provide a constant-temperature, constant-flow, and constant-pressure circulating cooling medium for heat-generating equipment, ensuring stable operation of the main equipment. After manufacturing, cooling water circulators must undergo rigorous performance testing, verifying key parameters such as outlet water temperature, flow rate, pressure, temperature stability, and cooling capacity to confirm that the overall performance indicators meet factory requirements.

[0003] Currently, the industry commonly uses manual testing methods for the performance testing of cooling water circulators. Testers follow a testing procedure, using decentralized testing tools such as thermometers, flow meters, and pressure gauges to manually record data under different operating conditions. The test results are then manually compared and calculated to determine whether the product is qualified. However, the existing testing method has the following technical drawbacks:

[0004] 1. The testing process is highly dependent on manual operation, resulting in low efficiency. A single device typically needs to undergo repeated tests at multiple set temperature points and under different load conditions. Testers need to frequently switch testing tools, manually adjust operating conditions, and record data. Testing a single device takes a long time, making it difficult to meet the testing cycle requirements of large-scale production.

[0005] 2. Test accuracy and consistency are difficult to guarantee. Because the testing tools are independent and lack a unified data acquisition and synchronization mechanism, human error exists in the timing of key parameter readings, load switching, and response times. Furthermore, manual reading, transcription, and calculation processes are prone to introducing errors, resulting in poor consistency of test results between different testers and different batches, making it difficult to achieve accurate and reproducible evaluation of the overall machine performance.

[0006] To improve testing efficiency, some existing technologies have introduced automated testing systems. However, these systems typically only collect and record a single parameter (such as temperature) and cannot simultaneously and dynamically coordinate the temperature, flow rate, pressure, and heat load of the circulating fluid. When simulating the actual operating conditions of a cooling water circulator, it is often necessary to simultaneously change multiple boundary conditions (such as set temperature, system resistance, and heat load). Existing testing equipment lacks the ability to adjust for the coupled changes of multiple parameters in real time, making it difficult to realistically simulate the dynamic response characteristics of the equipment under varying operating conditions. This results in discrepancies between factory test results and actual performance. Summary of the Invention

[0027] Example 1

[0028] like Figure 1 As shown, a circulating fluid multi-parameter dynamic control device according to a first aspect embodiment of the present invention includes an inlet pipe 10, an outlet pipe 11, a heater 6, an inlet temperature and pressure measuring mechanism, an outlet temperature and pressure measuring mechanism, a flow regulating mechanism, and a controller. One end of the inlet pipe 10 is provided with an inlet port 1, and the other end of the inlet pipe 10 is connected to the inlet port of the heater 6; one end of the outlet pipe 11 is provided with an outlet port 9, and the other end of the outlet pipe 11 is connected to the outlet port of the heater 6.

[0029] The inlet temperature and pressure measuring mechanism and the flow regulating mechanism are both installed on the inlet pipe 10, and the outlet temperature and pressure measuring mechanism is installed on the outlet pipe 11. The heater 6, the inlet temperature and pressure measuring mechanism, the outlet temperature and pressure measuring mechanism, and the flow regulating mechanism are all connected to the controller.

[0030] The controller can automatically adjust the flow rate from high to low through the flow regulation mechanism, and then monitor the inlet pressure, outlet pressure and circulating fluid flow rate to automatically plot the cooling water circulation machine pump performance curve; the controller can calculate the cooling power of the cooling water circulation machine by monitoring the inlet temperature, outlet temperature and circulating fluid flow rate and using the time-heating method.

[0031] In this embodiment, it should be noted that the controller includes a data acquisition module, a data processing module, and a control output module. The data acquisition module is used to acquire the detection signals from the inlet liquid temperature and pressure measuring mechanism, the outlet liquid temperature and pressure measuring mechanism, and the flow regulating mechanism. The data processing module is used to generate pump performance curves and cooling power data based on the detection signals. The control output module is used to output regulation commands to the flow regulating mechanism and the heater.

[0032] In addition, the controller is equipped with a display screen and a data export interface. The display screen is used to show key parameters such as temperature, pressure, and flow rate in real time, as well as the generated performance curves. The data export interface can be a USB interface, which is used to export test data to external devices for easy data storage, analysis and traceability.

[0033] The technical effects achieved in this embodiment are as follows: by integrating data acquisition, processing and control functions through the controller, the coordinated regulation of circulating fluid temperature, pressure, flow rate and heat load is realized. It can automatically complete the drawing of pump performance curves and the calculation of cooling power, which significantly improves the automation level and data accuracy of the testing process, reduces the errors and time consumption caused by manual intervention, and provides an efficient and reliable testing platform for the performance testing of cooling water circulators.

[0034] Example 2

[0035] like Figure 1 As shown in the figure, another circulating fluid multi-parameter dynamic control device provided in this embodiment has the same structure as in embodiment 1. Only the different parts are described below.

[0036] In this embodiment, the liquid inlet temperature and pressure measuring mechanism is located near the liquid inlet port 1. The liquid inlet temperature and pressure measuring mechanism includes a liquid inlet temperature sensor 2 and a liquid inlet pressure sensor 3. Both the liquid inlet temperature sensor 2 and the liquid inlet pressure sensor 3 are located on the liquid inlet pipe 10, and both the liquid inlet temperature sensor 2 and the liquid inlet pressure sensor 3 are connected to the controller.

[0037] The liquid temperature and pressure measuring mechanism is located near the liquid outlet port 9. The liquid temperature and pressure measuring mechanism includes a liquid temperature sensor 7 and a liquid pressure sensor 8. Both the liquid temperature sensor 7 and the liquid pressure sensor 8 are located on the liquid outlet pipe 11 and are connected to the controller.

[0038] The flow regulation mechanism includes an electric valve 4 and a flow sensor 5. Both the electric valve 4 and the flow sensor 5 are installed on the inlet pipe 10. The electric valve 4 is preferably an electric ball valve, which has the characteristics of fast response speed and high regulation accuracy. Both the electric valve 4 and the flow sensor 5 are connected to the controller.

[0039] In this embodiment, it should be noted that the outlet of the cooling water circulator is connected to the inlet port 1. The inlet temperature and pressure are detected by the inlet temperature sensor 2 and the inlet pressure sensor 3. Then, the circulation flow is automatically controlled by the electric valve 4. The flow sensor 5 converts the flow into an electrical signal and transmits it to the controller for display and recording. The load power is controlled by the heater 6. After being heated by the heater 6, the circulating liquid flows to the outlet port 9. The outlet temperature and pressure are detected by the outlet temperature sensor 7 and the outlet pressure sensor 8. Finally, the liquid flows back to the return port of the cooling water circulator, completing the system circulation.

[0040] The system adjusts the input voltage of the heater through the voltage regulation module to precisely control the heating power of the heater 6, thereby achieving flexible adjustment of the load power; after the cooling water circulator is connected to the inlet port 1 and the outlet port 9, the cooling water circulator is set to run in the cooling mode. By setting the heating power of the heater 6, it forms a counter-test with the cooling capacity of the cooling water circulator, thereby accurately detecting the cooling power of the cooling water circulator under different operating conditions.

[0041] The system obtains the cooling rate by monitoring the inlet liquid temperature sensor 2, and quickly calculates the cooling power of the cooling water circulator using the time-temperature rise method, realizing the power scanning function at different operating points. Simultaneously, the system monitors the inlet liquid pressure and circulation flow rate in real time through the inlet liquid pressure sensor 3 and the flow sensor 5. It automatically adjusts the opening of the electric valve 4 from large to small by controlling it, recording the pressure and flow data at different opening degrees, and automatically plotting the pump performance curve of the cooling water circulator, thereby achieving automated testing of pump performance.

[0042] The technical effects achieved in this embodiment are as follows: By integrating a temperature sensor, a pressure sensor, an electric valve, and a flow sensor into the inlet pipe 10 and the outlet pipe 11 respectively, a complete circulating fluid parameter detection and control loop is constructed, realizing real-time monitoring and closed-loop control of inlet temperature, inlet pressure, outlet temperature, outlet pressure, and circulating flow rate. The system can automatically complete load power adjustment, cooling power detection, power scanning, and pump performance curve plotting, further improving the automation and accuracy of the test, and providing complete hardware support for multi-parameter testing of cooling water circulators.

[0043] Example 3

[0044] like Figure 1 As shown in the figure, another circulating fluid multi-parameter dynamic control device provided in this embodiment has the same structure as in embodiment 1. Only the different parts are described below.

[0045] In this embodiment, the ease of use, safety and testing accuracy of the device are further optimized. Specifically, both the liquid inlet port 1 and the liquid outlet port 9 adopt self-sealing quick-release connectors, which can automatically cut off the liquid path during disassembly and assembly to prevent circulating liquid leakage. At the same time, it is convenient to quickly connect and replace the cooling water circulator under test, effectively improving testing efficiency and operation convenience.

[0046] In this embodiment, it should be noted that the inlet pipe 10 and the outlet pipe 11 are respectively equipped with a pressure relief valve and an exhaust valve. The pressure relief valve is used to automatically release pressure when the system pressure is abnormal, protecting the safety of the testing device and the device under test. The exhaust valve is used to discharge residual gas in the circulation pipeline, ensuring stable flow of the circulating liquid and avoiding the influence of gas resistance on the test accuracy. In addition, both the inlet pipe 10 and the outlet pipe 11 are equipped with an insulation layer. The insulation layer is made of rubber-plastic insulation material or polyurethane foam material to reduce heat loss of the circulating liquid during transmission and improve the stability of temperature control and the accuracy of test results.

[0047] The technical effects achieved by this embodiment are as follows: the use of quick-release connectors enables rapid connection and replacement between the device under test and the testing device, significantly improving testing efficiency; the installation of pressure relief valves and exhaust valves enhances the safety and operational stability of the system; and the installation of an insulation layer on the outside of the pipeline effectively reduces heat loss, improves the stability of temperature control, and enhances the reliability of test data.

[0048] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.

[0049] The terms such as "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity of description and are not intended to limit the scope of the invention. Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.
