Description

Technical Field

[0001] This invention belongs to the technical field of phase change condenser plates, and more specifically, it relates to a dual-channel phase change cold plate condensation performance testing device. Background Technology

[0002] As a core component in the field of heat dissipation and heat exchange, phase change cold plates are widely used in various temperature control and heat dissipation equipment. Their condensation heat dissipation performance and flow rate stability directly determine the overall heat dissipation effect and operational reliability. Therefore, before leaving the factory, it is necessary to use a special testing device to accurately test their condensation performance and flow rate heat dissipation effect to ensure the product's pass rate.

[0003] Currently, existing phase change cold plate condensation performance testing devices have many technical defects in actual use. Most existing testing equipment adopts a single water circuit testing structure, which cannot achieve dual-channel synchronous comparison testing, resulting in low testing efficiency. In addition, the overall operating condition control structure of the equipment is simple, which cannot monitor the inlet flow, outlet flow, and pipeline pressure of the test water circuit in real time. The test parameter acquisition dimension is single, making it difficult to ensure the uniformity of test conditions, resulting in poor integrity and standardization of cold plate condensation performance test data.

[0004] Meanwhile, the water circulation system of traditional testing devices lacks an effective pressure and flow stabilization structure. During the testing process, the water pressure fluctuates greatly and the flow rate decreases significantly. Under long-term continuous testing conditions, the stability of the operating conditions is insufficient, which can easily cause deviations in multiple sets of test data. This makes it impossible to guarantee the consistency of batch cold plate testing and to accurately reproduce the condensation and heat dissipation performance of the cold plate under actual working conditions.

[0005] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a dual-channel phase change cold plate condensation performance testing device in order to achieve a more practical and valuable purpose. Summary of the Invention

The layout is neat and the pipeline routing is clear. It can effectively avoid the vibration and heat interference of the condensation equipment operation to the upper test environment, ensure the stability of the internal working conditions of the test tube chamber 13, and facilitate the later equipment inspection and maintenance, thereby improving the overall operational stability and maintenance convenience of the equipment.

[0053] Preferred options are shown in the appendix. Figure 4 To be continued Figure 7 The liquid storage assembly 2 includes a condensate storage tank 21. From left to right, the condensate storage tank 21 is equipped with a condensate drain pipe 48, a second inlet sleeve 23, a third inlet sleeve 24, a first inlet sleeve 22, and an inlet sleeve assembly 25.

The end of the inlet metering valve 36 is fixedly connected to the condensation device 4. A pressure transmitter 34 is fixedly installed on the pipe of each of the first test connectors 31. The two sets of first test connectors 31 and two sets of second test connectors 32 form a dual-channel independent test structure, which can simultaneously connect to two sets of condensation test plates 37 for synchronous comparative testing, significantly improving testing efficiency. Combined with the pressure transmitter 34 and the inlet / drain metering valves, pressure and flow parameters are monitored in real time, enabling real-time quantitative acquisition of pressure and flow data. This ensures that each set of test data is traceable and comparable, effectively improving detection accuracy and equipment versatility.

[0055] Preferred options are shown in the appendix. Figure 1 To be continued Figure 6 The condensation device 4 includes a pressurizing pump 43, a gas storage tank 41, and an atomizing condenser device 47. The gas storage tank 41 and the atomizing condenser device 47 are installed side by side. The pressurizing pump 43 is fixedly installed behind the gas storage tank 41. A pressurizing pipe 44 is fixedly connected to the outside of the atomizing condenser device 47. The pressurizing pipe 44 is fixedly connected to the liquid inlet metering valve 36. A flow metering valve 35 is provided between the liquid inlet metering valve 36 and the atomizing condenser device 47. A condensation test plate 37 is fixedly connected to the first test connector 31 and the second test connector 32. The gas storage tank 41, the pressurizing pump 43, and the atomizing condenser device 47 form a complete constant temperature, pressurization, and cooling closed-loop system, which can simulate the full working environment of the cold plate under the conditions of heating, pressurization, heat dissipation, and cooling. With the help of multiple flow metering valves, the circulating flow data can be collected in real time and accurately, which can truly restore the actual heat dissipation and flow performance of the condensation test plate 37, avoid the detection deviation caused by single working condition testing, and greatly improve the authenticity and reliability of the test.

[0056] Preferred options are shown in the appendix. Figure 4 To be continued Figure 10The pressurizing pump 43 includes a drive motor 431, a pressurizing shell 432, and a crushing and grinding shell 434. The front end of the drive motor 431 is equipped with the pressurizing shell 432, and the rear end of the drive motor 431 is equipped with the crushing and grinding shell 434.

An air inlet metering valve 26 is fixedly installed between the drain pipe 42 and the third liquid inlet sleeve 24. The water outlet pipe 46 is connected to the first liquid inlet sleeve 22. The pressurizing pump 43 adopts an integrated front and rear dual-section structure. The front end is responsible for pressurizing and delivering water, and the rear end is responsible for crushing and grinding dirt. A single motor synchronously drives two sets of functional structures. The equipment has high integration, compact structure, and low energy consumption. With the help of the air inlet metering valve 26, the air inlet pressurization can be precisely controlled to stabilize the high-pressure environment of the pipeline, making the water pressurization more uniform and controllable, and providing a stable power foundation for subsequent dirt crushing and circulation.

[0057] Preferred options are shown in the appendix. Figure 9 To be continued Figure 10 The liquid inlet sleeve assembly 25 includes a liquid inlet sleeve 251 and an intercepting drain pipe 252. One end of the liquid inlet sleeve 251 is fixedly connected to the water outlet of the condensate storage tank 21.

The shaft is fixedly connected, and the other end of the drive motor 431 is fixedly connected to a pressure impeller 433. The pressure impeller 433 is set inside the pressure housing 432. The liquid inlet sleeve assembly 25 integrates suction, circulation, dirt interception, and sewage discharge functions. The scale is broken down and refined by the high-speed rotation of the crushing blades 435, and the impurities are then intercepted by the dirt interception block 253. Finally, the sewage is discharged through the drain valve 254. The circulating water can be continuously purified without disassembling the machine or affecting normal testing. This fundamentally solves the defects of traditional equipment such as scale accumulation, pipe blockage, flow attenuation, and data drift during long-term operation, and ensures long-term high-precision and stable operation of the equipment.

[0058] Preferred options are shown in the appendix. Figure 11 To be continued Figure 12The condensate storage tank 21 includes a storage tank 211, which has an internal cavity. Several sets of condenser tubes 215 are fixedly installed inside the cavity. An annular groove 214 is provided between the condenser tubes 215 and the inner wall of the storage tank 211. The condenser tubes 215 divide the interior of the storage tank 211 into an inlet chamber and a drain chamber. The inlet chamber is filled with a filter plate 217, and the drain chamber has a drain cavity 212. The storage tank 211 adopts a cavity partitioning structure design, separating the inlet and outlet chambers through the condenser tubes 215. With the filter plate 217 in the inlet chamber, large particles of impurities can be intercepted in advance, preventing impurities from entering the condenser tubes 215 and causing wear and blockage. The annular groove 214 provides a stable sliding track for the internal moving cleaning structure, effectively taking into account water filtration, pressure stabilization and buffering, and dynamic self-cleaning functions, greatly improving the cleanliness of the water circuit and the stability of operation.

[0059] Preferred options are shown in the appendix. Figure 11 To be continued Figure 12 The annular groove 214 and the water inlet chamber are internally connected to the first liquid inlet sleeve 22, the second liquid inlet sleeve 23 and the third liquid inlet sleeve 24. A tension spring 216 is movably installed inside the condenser tube 215.

Multiple sets of sleeves are interconnected with the annular groove 214 to ensure uniform water flow and consistent pressure transmission. Through the water pressure adaptive expansion and contraction characteristics of the tension spring 216, the internal pressure back plate assembly 213 can be automatically driven to slide back and forth according to the pressure change in the tank, realizing fully automatic and adaptive tube wall scraping and cleaning without additional electrical control drive. The structure has strong linkage and high degree of automation, and continuously keeps the inner wall of the condenser tube 215 clean and unobstructed.

[0060] Preferred options are shown in the appendix. Figure 11 To be continued Figure 12The internally pressurized backplate assembly 213 includes a circular partition 2131.

The sealing plate and the internally pressurized backplate assembly 213... 3. An internal cavity is formed, and the swing spring 2133 is disposed in the cavity. The drain port 2132 is connected to the cavity. The internal pressure back plate assembly 213 achieves sealing and pressure stabilization through the sliding of the annular piston. It works with the sealing plate through the hole to achieve normal water flow and scale prevention and isolation. The circular partition 2131 structure forms a high-speed internal vortex. Combined with the elastic impact effect of the swing spring 2133 and the spherical swing component 2134, it can further break up and refine the detached scale, realizing the integrated self-cleaning function of "scraping scale-accumulating scale-breaking-draining". It completely solves the industry pain points of long-term scale accumulation in traditional testing devices, which leads to reduced flow rate, large testing error and high defect rate. It significantly improves the service life of the equipment and the accuracy of testing.

[0061] Specific usage of this invention:

[0062] When using this device, first install it in the testing laboratory, completing equipment fixation and basic debugging. Then, match and connect the device's inlet and outlet pipes to their corresponding interfaces, prioritizing the connection of the external inlet pipe to the gas storage tank 41, ensuring the sealing and stability of the pipe connection. After the pipe connection is complete, connect the device to the power supply and complete the setting of the test program and operating parameters through the built-in control system. After the program is set, precisely connect and fix the two sets of first test connectors 31 and two sets of second test connectors 32 inside the test chamber 13 to the condensation test plate 37 to be tested. After the connection is completed, press the device start button to start the flow rate and heat dissipation effect test of the condensation test plate 37. After the device starts running, the heating component inside the gas storage tank 41 starts working, maintaining a constant temperature for the stored water, and stabilizing the test water temperature within the standard test range of 40-50℃. This device adopts standardized installation and connection and programmed parameter setting, and with the constant temperature control structure of the gas storage tank, it can unify the working environment of each test group, effectively avoid test errors caused by pipeline leakage, pressure loss and water temperature fluctuation, and greatly improve the uniformity, accuracy and comparability of test data of multiple batches of condensation test plates, ensuring consistent working conditions of dual-channel tests.

[0063] During the formal testing process, the constant-temperature water inside the gas storage tank 41 is transported to the condensate storage tank 21 under the drive of the pressurization structure, completing the water buffering and pressure stabilization treatment. The pressure-stabilized water inside the condensate storage tank 21 flows sequentially into the first test connector 31, the condensation test plate 37, and the second test connector 32 to complete the heat exchange performance test with the condensation test plate 37. After the test, the water is transported to the atomizing condenser device 47 for rapid cooling, and the cooled water flows back into the gas storage tank 41, thus forming a closed-loop water circulation test system. The closed-loop circulating water circuit formed by the overall pipeline structure can realize uninterrupted continuous testing of the equipment without the need for frequent manual water replenishment and replacement, effectively improving testing efficiency; at the same time, the condensate storage tank 21 can buffer and stabilize the test water, avoiding sudden water pressure changes from impacting the test pipeline and the test plate, ensuring the water pressure stability of the dual-channel synchronous testing process, and adapting to the needs of dual-channel batch testing operations.

[0064] During the equipment cyclic testing, the drain pipe 42 and outlet pipe 46 at the front end of the pressurizing pump 43, together with the second inlet sleeve 23 and the third inlet sleeve 24, form a cyclic pressurizing loop, continuously providing high-pressure power to the water inside the condensate storage tank 21, ensuring that the water inside the tank remains under high-pressure testing conditions. Simultaneously, the pressure transmitter 34 mounted on the first test connector 31 monitors the pipeline pressure in real time, precisely controlling the water discharge flow rate. The inlet and outlet flow rates are collected and statistically analyzed in real time through the inlet metering valve 36, flow metering valve 35, and outlet metering valve 33, respectively. The collected flow and pressure data are transmitted in real time to the background control system for calculation and analysis, accurately detecting whether the cooling and flow performance of the condensate test plate 37 meets the standards at the time of factory shipment. The high-pressure cyclic loop constructed by the pressurizing pump can simulate the actual high-pressure working conditions of the phase change cold plate, improving the realism and accuracy of the test. Multiple sets of metering valves and pressure transmitters work together to achieve precise quantitative acquisition of test data, replacing traditional manual observation and testing methods, effectively reducing human error, and significantly improving the accuracy and pass rate of the condensate test plate's factory quality inspection.

[0065] Traditional testing devices of this type cannot automatically clean scale and deposits that accumulate in the condensate storage tank and pipelines during long-term operation. Long-term scale buildup narrows the pipe orifice diameter and increases water flow resistance, causing the test water flow rate to continuously slow down. This results in significant deviations in the flow rate and cooling data of the condensation test plate, with a continuously increasing test error. Consequently, the device cannot accurately reflect the actual condensation and heat dissipation performance of the cold plate, easily leading to the misclassification of good products as defective products and the failure to detect unqualified products, significantly increasing the false defect rate and the company's quality inspection costs.

[0066] During operation, the pressurizing pump 43 maintains a continuous pressurizing cycle. This constant high-pressure water flow continuously agitates the water inside the condensate storage tank 21, inhibiting the settling, adhesion, and growth of scale at its source, thus achieving initial scale control. Simultaneously, the drive motor 431 inside the pressurizing pump 43 synchronously drives the front-end pressurizing impeller 433 and the rear-end crushing blades 435 to rotate at high speed, constructing a high-intensity high-pressure water flow circulation system. The high-pressure water flow is rapidly introduced into the condensate storage tank 21 through the drain pipe 42 and the outlet pipe 46, further accelerating the water flow within the tank. This structure integrates pressurized water supply, water circulation agitation, and scale pretreatment functions into one unit, eliminating the need for additional auxiliary drive equipment. It is compact and consumes less energy. By continuously suppressing scale accumulation through dynamic water flow agitation, the device achieves all-weather dynamic scale prevention without affecting normal testing operations, continuously ensuring smooth water flow and alleviating the problem of decreased testing accuracy caused by long-term scale buildup.

[0067] During the high-speed rotation of the crushing blade 435, water and suspended impurities inside the condensate storage tank 21 are drawn in through the intercepting drain pipe 252, and the water is circulated through the inlet sleeve 251. Water continuously enters the storage tank 211, and high-pressure water flows into the condenser tube 215. Due to the blocking and flow-limiting effect of the internal pressure back plate assembly 213, the water pressure inside the storage tank 211 gradually increases, pushing the tension spring 216 to stretch and deform, and simultaneously driving the internal pressure back plate assembly 213 to slide smoothly to the rear end. During the reciprocating stretching and resetting process inside the condenser tube 215, the tension spring 216 continuously scrapes the inner wall of the condenser tube 215, peeling off the stubborn scale and hard dirt attached to the tube wall. At the same time, the reciprocating deformation of the spring can shake off the scale and impurities attached to it. The detached scale and impurities are collected and stored in the cavity between the internal pressure back plate assembly 213 and the sealing plate. The device utilizes its own water pressure changes to adaptively drive the scraping structure, eliminating the need for additional electrical control or manual operation. It can automatically adapt to different test pressure conditions, accurately removing stubborn scale from the pipe wall and solving the technical pain point that traditional equipment cannot clean scale adhering to the inner wall. At the same time, the sealing plate can isolate large impurities, preventing dirt from entering the test channel and interfering with the detection, so that the testing and descaling operations can be carried out simultaneously without interference.

[0068] Unevenly sized scale and impurities accumulated inside the cavity will continuously collide and impact with the swing spring 2133 and spherical swing element 2134 at the end of the drain port 2132 as the water flows through it, thus initially breaking up large pieces of scale. Simultaneously, the circular baffle 2131, with its semi-circular top and flat bottom structure, allows the water flow inside the cavity to form a high-speed vortex, quickly discharging the scale and impurities from the drain port 2132. The discharged scale-containing water flows into the crushing and grinding shell 434 through the inlet sleeve 251. The high-speed rotating crushing blades 435 further refine and grind the blocky scale, completely pulverizing it into fine particles. As the refined scale and impurities flow through the inlet sleeve 251, they are precisely intercepted by the internal dirt interception block 253, causing the fine scale to remain suspended inside the interception drain pipe 252, effectively separating the impurities from the test water. Through a multi-stage descaling structure that combines hydraulic vortex, elastic impact, mechanical grinding, and impurity interception, scale can be refined and collected step by step, completely eliminating the problems of large scale clogging pipes and fine impurities causing disturbances during testing. This ensures the stability of water flow and the accuracy of test data, effectively reducing the frequency of equipment failures and the workload of daily maintenance.

[0069] After long-term continuous operation of the equipment, if the testing personnel find multiple sets of abnormal test data and determine that the equipment has serious scale buildup, they can open the drain valve 254 at the lower section of the inlet sleeve 251, while maintaining continuous water intake through the water inlet pipe of the air storage tank 41. Using external clean water, a reverse high-pressure flushing flow is formed to thoroughly backwash the entire circulating water system, condensate storage tank 21, condenser pipe 215, and all connecting sleeves, removing trapped and retained scale and impurities from the pipes, thus completing a thorough cleaning of the equipment. This reverse flushing structure is easy to operate, requires no disassembly, and can quickly complete the descaling and cleaning of the entire water system, efficiently restoring the equipment's water flow performance and testing accuracy. It significantly reduces equipment downtime and maintenance costs, effectively ensuring long-term, stable, and high-precision operation of the device, fundamentally solving the problems of large testing errors and high defect rate caused by scale buildup in traditional equipment.

[0070] This invention discloses a dual-channel phase change cold plate condensation performance testing device. By integrating a liquid storage component 2, a temperature measuring component 3, and a condensation device 4 within the main testing unit 1, and by equipping the temperature measuring component 3 with multiple sets of metering valves and pressure transmitters 34, it can achieve real-time synchronous monitoring and data statistics of the inlet and outlet flow rate and pressure of the test water circuit. This replaces the traditional single-parameter detection mode, effectively standardizes the test conditions, ensures the uniformity of the test conditions in the dual-channel cold plate testing process, and improves the integrity and standardization of condensation performance test data.

[0071] The present invention discloses a dual-channel phase change cold plate condensation performance testing device. Through the linkage of the pressurizing pump 43, the condensate storage tank 21 and the internal pressurizing backplate assembly 213, the pressurizing pump 43 continuously provides circulating high pressure power, and the internal pressurizing backplate assembly 213 has an adaptive sliding flow limiting effect to stabilize the internal water circulation pressure and flow state of the device. This avoids the defects of water circuit pressure fluctuation and flow attenuation in traditional testing equipment, effectively improves the overall operational stability of the device, and ensures the consistency of detection under long-term continuous testing conditions.

[0072] This invention discloses a dual-channel phase change cold plate condensation performance testing device. By incorporating a tension spring 216 and an internal pressure back plate assembly 213 with a swing impact structure inside the condensate storage tank 21, along with a crushing and grinding shell 434 at the rear end of the pressure pump 43 and a dirt interception structure in the liquid inlet sleeve assembly 25, an integrated self-cleaning system is formed, which integrates mechanical adaptive scraping, hydraulic vortex scale breaking, mechanical grinding refinement, and concentrated impurity interception. This system can automatically clean the pipes and tank of scale and impurities while the equipment is operating normally, thus preventing water blockage, abnormal flow rate, and test data deviation caused by scale buildup. It effectively reduces the probability of misjudgment in cold plate quality inspection, reduces the frequency of equipment disassembly and maintenance, and significantly improves the service life of the equipment and its long-term high-precision testing capabilities.
