Description

Technical Field

[0001] The present invention relates to the technical field of water flow rate testing of water cooling plates, and particularly relates to a water flow rate testing process and device for water cooling plates. Background Technique

[0002] In modern industry, a water cooling plate, also known as a liquid cooling plate or a water cooling cooler, is an efficient cooling device widely used in fields such as electronic products, computers, industrial equipment, and medical equipment. A water cooling plate is an element that exchanges heat through liquid cooling. The principle is to form flow channels inside a metal plate. Electronic components are installed on the surface of the plate. The coolant enters from the plate inlet and exits from the outlet, taking away the heat generated by the components. Common processes for forming the flow channels of water cooling plates include friction welding, vacuum brazing, buried copper tubes, deep hole drilling, etc. The performance of the water cooling plate directly affects its cooling effect, and the water flow rate is one of the key factors affecting the performance of the water cooling plate. Therefore, developing an accurate and efficient water flow rate testing process for water cooling plates is of great significance for ensuring product quality.

[0003] There is a currently authorized publication number CN114269117A for a water cooling plate, which includes a base plate and an upper cover. The base plate includes a plate body; a first guide groove formed on the upper surface of the plate body, with a first liquid inlet and a first liquid outlet respectively provided on two opposite groove walls. A first cooling area is provided in the first guide groove. The first cooling area is provided with a plurality of parallel and spaced first rib plates, and a first flow channel is formed between adjacent two first rib plates. The two ends of the first flow channel are respectively communicated with the first liquid inlet and the first liquid outlet; a second guide groove is provided on the side of the first cooling area in the first guide groove, with a second liquid outlet and a second liquid inlet close to the first liquid inlet respectively provided on two opposite groove walls. The second liquid inlet, the second liquid outlet, the first liquid inlet, and the first liquid outlet all overlap; a second cooling area is provided in the second guide groove. The second cooling area is provided with a plurality of parallel and spaced second rib plates, and a second flow channel is formed between adjacent two second rib plates. The two ends of the second flow channel are respectively communicated with the second liquid inlet and the second liquid outlet. However, this cooling plate has not been tested by a testing device. The cooling plate needs to be tested and then optimized before it can be used.

[0004] Therefore, the present invention proposes a water flow rate testing process and device for water cooling plates to observe the use effect of the testing device to solve such problems. Summary of the Invention

[0005] To achieve the above object, the present invention proposes a water flow rate testing process and device for water cooling plates, including the following steps: Step 1. Preparation stage: Fix the water cooling plate to be tested on the test bench and connect the water pipe and the sensor; Step 2. Initialization setting: Set the test parameters, including the inlet water pressure, flow rate range, and test time; Step 3. Start the test: Start the water pump, adjust the control module to make water pass through the water-cooled plate, and monitor the changes in water flow and pressure in real time; Step 4. Data recording: Use a data acquisition system to record various data during the test process; Step 5. Result analysis: Calculate the water flow and pressure loss of the water-cooled plate based on the recorded data and evaluate its performance.

[0006] In one example, in the said Step 1, the water-cooled plate is composed of an upper cover plate, a lower cover plate and an internal flow channel. The upper cover plate and the lower cover plate are made of aluminum alloy or copper alloy materials, which have good thermal conductivity and mechanical strength. The internal flow channel is formed by micro-hole processing technology to ensure the smoothness and uniformity of the water flow channel.

[0007] In one example, the sensors include a water flow sensor and a pressure sensor. The water flow sensor is used to measure the water flow into and out of the water-cooled plate, and the pressure sensor is used to monitor the water pressure at the inlet and outlet of the water-cooled plate. The data acquisition system records and analyzes the test data, and the control module adjusts the water flow state according to the preset parameters.

[0008] On the other hand, the present application also provides a water flow test device for a water-cooled plate, including an upper cover. A heat-conducting boss is fixedly connected to the top surface of the upper cover. A substrate body is movably connected to the bottom of the upper cover. A circular hole is formed in the middle of the substrate body. A first guide groove section is fixedly connected to one side of the middle of the substrate body, and a second guide groove section is fixedly connected to the other side of the middle of the substrate body.

[0009] In one example, a liquid outlet and a liquid inlet are respectively formed in the front and rear sides of the middle of the substrate body. A water outlet pipe is movably connected to the inside of the liquid outlet, and a second sensor is fixedly connected to the outside of the water outlet pipe. A water inlet pipe is movably connected to the inside of the liquid inlet, and a first sensor is fixedly connected to the outside of the water inlet pipe. The groove wall of the liquid inlet is the liquid inlet groove wall, and the groove wall of the liquid outlet is the liquid outlet groove wall. The liquid inlet groove wall includes a first guide groove section inclined from the liquid inlet to the adjacent groove wall. The liquid outlet groove wall includes a second guide groove section inclined from the liquid outlet to the adjacent groove wall. The distance between the liquid inlet groove wall and the liquid outlet groove wall gradually decreases in the direction extending from the liquid inlet to the other side.

[0010] In one example, a third guide groove is fixedly connected to one side inside the substrate body, a second guide groove is fixedly connected to the other side inside the substrate body, and a first guide groove is fixedly connected to the middle inside the substrate body. A first guide groove section and a second guide groove section are respectively arranged on both sides of the first guide groove.

[0011] In one example, the upper cover includes: a plate body, a first guide groove formed on the upper surface of the plate body, a liquid inlet and a liquid outlet are respectively provided on two opposite groove walls of the first guide groove, and a plurality of parallel and spaced protruding first rib plates are provided on the groove bottom inside the first guide groove. A second guide groove is provided inside the first guide groove, and a plurality of parallel and spaced second rib plates are provided on the groove bottom inside the third guide groove, and a flow channel is formed between two adjacent second rib plates.

[0012] In one example, the openings of the first guiding groove section and the second guiding groove section are opposite, the liquid outlet and the liquid inlet are respectively located at two ends of the first guiding groove section and the second guiding groove section, and the first guide groove is located in the middle of the first guiding groove section and the second guiding groove section.

[0013] The water flow rate testing process and device for a water cooling plate proposed by the present invention can bring the following beneficial effects: 1. The testing device of the present invention adopts a double-station design and can simultaneously test two different types of water cooling plates. This design significantly improves the testing speed and reduces the time cost of a single test. It is particularly suitable for large-scale production or performance evaluation of various water cooling plates. At the same time, the structural design of the device allows for flexible adjustment and can adapt to water cooling plates of different sizes and types, enhancing the versatility and applicability of the testing device. A water pipe connector is used to connect the water inlet hole of the water cooling plate to the water source of the water pressure testing device to ensure good sealing at the connection.

[0014] 2. The testing device is equipped with a water flow sensor and a pressure sensor, which can monitor the water flow rate and pressure changes at the inlet and outlet of the water cooling plate in real time. Through the cooperation of an accurate data acquisition system and a control module, the testing process realizes automation and intelligence. This design not only improves the testing accuracy and repeatability but also ensures the reliability and accuracy of the testing data. The water outlet hole of the water cooling plate is connected to a water flow meter to measure the water flow rate.

[0015] 3. The internal structural design of the testing device, such as the inclined layout of the first guiding groove section and the second guiding groove section, and the rib plate design inside the guide groove, can effectively guide the flow of the cooling liquid, reduce the turbulence phenomenon, optimize the flow rate and flow distribution of the cooling liquid, provide a stable flow environment for the accurate measurement of the water flow rate, and make the test results better reflect the performance of the testing device under actual working conditions. The amount of water inlet can be adjusted according to the actual situation, and the water flow rate of the water cooling plate is tested by observing the water flow rate at the position of the water outlet hole.

Detailed implementation manners

[0022] In order to more clearly illustrate the overall concept of the present invention, the following will be described in detail by way of examples in conjunction with the drawings in the specification.

[0023] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0024] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality" means two or more, unless otherwise specifically defined.

[0025] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "coupled", "fixed", etc. shall be construed in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection, an electrical connection, or a communication connection; it may be directly connected, or indirectly connected through an intermediate medium, and may be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] In the present invention, unless otherwise clearly specified or limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. In the description of this specification, the description with reference to terms such as "one solution", "some solutions", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the solution or example are included in at least one solution or example of the present invention. In this specification, the schematic expressions of the above terms do not necessarily refer to the same solution or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more solutions or examples.

[0027] Please refer to Figures 1-4 , the present invention provides a water cooling plate, which includes an upper cover plate, a lower cover plate, and an internal flow channel. The upper cover plate and the lower cover plate are fixed by bolts, and the internal flow channel is formed by micro-hole processing technology to ensure the smoothness and uniformity of the water flow channel.

[0028] Test preparation, equipment connection: Uncover the side of the water cooling plate that needs to test the water flow rate to expose the inside, connect the water pipe to the water cooling plate, and pay attention to checking that the water pipe is normal and ensure that the connection is tight without leakage.

[0029] After connecting two water pipes with a water pipe connector, ensure that the connection is well sealed, and perform an inflation operation above the water cooling plate for subsequent detection of relevant information. At the same time, connect two display water pressure gauges, which are respectively installed at the water inlet and outlet positions, and connect the water outlet hole of the water cooling plate to the water flow meter to measure the water flow rate.

[0030] Test equipment preparation: Prepare a device for filling water, fill the water from the water source in the water pressure test device into the test system, and ensure that the air is connected to 5 products, and then perform a ventilation operation to check the relevant situation after ventilation.

[0031] Test the water pressure at 5 bar - 1.5 Mpa, the water flow rate at 6 liters per minute. The test duration may be affected by other factors, such as various parameter changes during the test, etc. There is a control switch for controlling the water flow size so that the water flow rate can be adjusted during the test.

[0032] For the preliminary test, first fill the water-cooled plate with water, then start ventilating, and observe the situation of relevant detection information streams. During this process, observe whether there are any abnormal plan-related situations in the follow-up. At the same time, control the water flow rate through the control switch. The size of the water inlet volume can be adjusted according to the actual situation. By observing the water flow rate at the water outlet hole position, test the water flow rate of the water-cooled plate, so as to observe the water flow situation of the water-cooled plate at different flow rates. For example, if the flow rate needs to reach 5.7 liters per minute and the pressure needs to reach 1.5 MPa, check whether the water-cooled plate can work normally and whether all parameters meet the requirements.

[0033] Measuring the water flow and related detections are separate and independent. The water flow part can be tested separately first to check whether the water flow rate can meet the requirements, reconfirm whether the water flow rate meets the expectations, and observe the change of the water flow rate in the operation of the control module, etc. It is also possible to test the air pressure part to see whether the air pressure-related situation meets the standards. Although this part may not be directly strongly related to the water flow rate test, it is a relevant process in the overall performance test of the water-cooled plate.

[0034] It is possible to have two workpieces tested at one station. One test station can test two pieces simultaneously, that is, there are two interfaces and two different types of workpieces can be tested at the same time. That is to say, this test process can adapt to the water flow rate tests of different types of workpieces and can be carried out simultaneously to improve the test efficiency. During the test, closely monitor the operating status of each device, such as the flowmeter, pressure gauge, etc., to ensure that their readings are normal and stable. If any abnormal situation is found, such as water leakage, abnormal pressure fluctuation, the flow rate cannot reach the requirement, etc., immediately stop the test, troubleshoot the problem and start the test again after solving it. The entire test process is preferably carried out in a suitable environment to avoid external factors interfering with the test results, such as staying away from vibration sources, high-temperature sources and other environments that may affect the water flow rate and related parameters.

[0035] In modern industrial production and scientific research fields, the accurate measurement of the water flow rate of the water-cooled plate plays a crucial role in ensuring the cooling performance and stable operation of the equipment. And there is a test device dedicated to the water flow rate test process of the water-cooled plate, and its unique design and structure provide a solid foundation for accurate measurement.

[0036] The test device is mainly composed of an upper cover 1 and a substrate body 2. On the top surface of the upper cover 1, a heat-conducting boss 3 is firmly connected. The setting of the heat-conducting boss 3 can efficiently transfer heat to a specific area to simulate the heat conduction environment in actual work, making the test results more in line with the actual application scenario. The bottom of the upper cover 1 is movably connected to the substrate body 2. This connection design not only facilitates the assembly and disassembly of the device, which is convenient for subsequent maintenance and debugging, but also ensures the close cooperation between the two during the test. A round hole is opened in the middle of the substrate body 2, which may play a key role in the fluid circulation or structural stability of the entire device. At the same time, a first guiding groove section 11 is fixedly connected to one side of the middle of the substrate body 2, and a second guiding groove section 12 is fixedly connected to the other side. These two guiding groove sections provide a precise guiding path for the flow of the coolant, which is of great significance for the accuracy of subsequent flow measurement.

[0037] Delving deeper into the detailed structure of the device, an outlet 14 and an inlet 15 are respectively and carefully arranged on the front and back sides of the middle of the substrate body 2. An outlet pipe 10 is movably connected inside the outlet 14, and a second sensor 9 is fixedly installed outside the outlet pipe 10. Its function is to monitor the relevant parameters of the outflowing coolant in real time, such as flow rate, temperature, etc., providing key data support for subsequent data analysis. An inlet pipe 5 is movably connected inside the inlet 15, and a first sensor 4 is fixedly installed outside the inlet pipe 5. The first sensor 4 is responsible for monitoring the various parameters of the inflowing coolant. The groove wall of the inlet 15 is defined as the inlet groove wall, and the groove wall of the outlet 14 is the outlet groove wall. It is worth mentioning that the inlet groove wall includes a first guiding groove section 11 that slopes from the inlet 15 to the adjacent groove wall, and the outlet groove wall includes a second guiding groove section 12 that slopes from the outlet 14 to the adjacent groove wall. This unique inclined design cleverly guides the flow direction of the coolant, reducing the turbulent flow phenomenon of the fluid, enabling the coolant to flow in and out of the cooling area of the water-cooled plate more smoothly. Moreover, the distance between the inlet groove wall and the outlet groove wall gradually decreases from the inlet 15 towards the cooling area of the water-cooled plate, further optimizing the flow rate and flow distribution of the coolant, which helps to measure the water flow more accurately.

[0038] Looking at the internal structure of the substrate body 2, a third guiding groove 13 is fixedly connected to one side, a second guiding groove 7 is fixedly connected to the other side, and a first guiding groove 6 is fixedly connected in the middle. These three guiding grooves work together to provide sufficient cooling space for the coolant, effectively simulating the cooling process of the water-cooled plate in actual work. It should be noted that the first guiding groove section 11 and the second guiding groove section 12 are respectively arranged on both sides of the first guiding groove 6, which further strengthens the guidance of the coolant flow direction, ensuring that the coolant can flow evenly through the first guiding groove 6, so as to facilitate more efficient cooling of the water-cooled plate during actual work.

[0039] Focusing again on the structural characteristics of the upper cover 1, it mainly includes a plate body 8. A first guide groove 6 is formed on the upper surface of the plate body 8. The first guide groove 6 and the substrate body 2 together enclose a cavity, and the existence of the cavity provides the necessary space for the heat exchange between the coolant and the heat source. On two opposite groove walls of the first guide groove 6, a liquid inlet 15 and a liquid outlet 14 are respectively arranged, enabling the coolant to enter and exit the guide groove orderly. On the bottom of the first guide groove 6, multiple parallel and spaced protruding first rib plates are provided, and these rib plates greatly increase the contact area between the coolant and the guide groove wall, significantly improving the cooling efficiency during the operation of the water cooling plate. A second guide groove 7 is arranged in the first guide groove 6, and a first cooling area is located on the side of the second guide groove 7. This layout further optimizes the utilization of the cooling space during the operation of the water cooling plate. On the bottom of the third guide groove 13, multiple parallel and spaced second rib plates are provided, and flow channels are formed between adjacent two second rib plates. The coolant flows in these flow channels, further enhancing the cooling effect during the operation of the water cooling plate and at the same time providing a stable flow environment for accurately measuring the water flow rate.

[0040] In addition, the openings of the first guide groove section 11 and the second guide groove section 12 are opposite. The liquid outlet 14 and the liquid inlet 15 are respectively located at both ends of the first guide groove section 11 and the second guide groove section 12, and the first guide groove 6 is located in the middle of the first guide groove section 11 and the second guide groove section 12. Such a layout design forms a scientific and reasonable coolant flow circulation path, enabling the coolant to flow orderly in the device, flowing in from the liquid inlet 15, flowing through the guide groove, and then flowing out from the liquid outlet 14. The whole process is smooth and efficient, providing a reliable guarantee for the practical application of the water flow rate of the water cooling plate.

[0041] The working principle of this patent is as follows: uncover the side of the water cooling plate that needs to test the water flow rate to expose the inside. When connecting the water pipe, ensure that the water pipe is normal and the connection is tight without water leakage. Conduct an inflation operation above the water cooling plate, and at the same time connect two display water pressure gauges, which are respectively installed at the water inlet and outlet positions. Prepare a device for filling water, pour water into the test system, and ensure that after connecting with 5 products, conduct a ventilation operation. The purpose of the ventilation operation is to check the operation of the entire test system after ventilation and check whether there is any blockage or other abnormal conditions. First, fill the water cooling plate with water, and then start ventilation and observe the situation of relevant detection information streams.

[0042] The measurement of water flow and related detections are separate and independent. The water flow part can be tested separately first. Check whether the water flow rate can meet the requirements, reconfirm whether the water flow rate meets the expectations, observe the change of the water flow rate in the operation of the control module, etc. It is also possible to test the air pressure part to see if the related air pressure conditions meet the standards. During the test process, closely monitor the operating status of each device, such as the flow meter, pressure gauge, etc., to ensure that their readings are normal and stable. If any abnormal situations are found, such as water leakage, abnormal pressure fluctuations, the flow rate not meeting the requirements, etc., the test should be stopped immediately, the problem should be investigated and solved, and then the test should be restarted.

[0043] The working principle of the test device: The test device is mainly composed of an upper cover 1 and a base plate body 2. The top surface of the upper cover 1 is connected with a heat conduction boss 3, which can efficiently transfer heat to a specific area, simulate the heat conduction environment in actual work, and make the test results more in line with the actual application scenario. The bottom of the upper cover 1 is movably connected to the base plate body 2, which is not only convenient for the assembly and disassembly of the device, facilitating subsequent maintenance and debugging, but also can ensure the close cooperation of the two during the test, guaranteeing the stability and accuracy of the test.

[0044] On the front and back sides of the middle part of the base plate body 2, a liquid outlet 14 and a liquid inlet 15 are respectively arranged. The inside of the liquid outlet 14 is movably connected with a water outlet pipe 10, and the inside of the liquid inlet 15 is movably connected with a water inlet pipe 5. This connection method enables the coolant to flow in and out of the test device smoothly, realizing the circulating flow of the coolant.

[0045] A second sensor 9 is fixedly installed outside the water outlet pipe 10 for real-time monitoring of relevant parameters of the outflowing coolant, such as flow rate, temperature, etc. A first sensor 4 is fixedly installed outside the water inlet pipe 5, responsible for monitoring various parameters of the inflowing coolant. By monitoring the parameters of the incoming and outgoing coolant through these two sensors, detailed data of the coolant during the entire test process can be obtained, providing key support for subsequent data analysis, so as to accurately evaluate the water flow performance of the water-cooled plate.

[0046] The openings of the first guide groove section 11 and the second guide groove section 12 are opposite. The liquid outlet 14 and the liquid inlet 15 are respectively located at both ends of the first guide groove section 11 and the second guide groove section 12, while the first guide groove 6 is located in the middle of the first guide groove section 11 and the second guide groove section 12. Such a layout design forms a scientific and reasonable coolant flow circulation path, enabling the coolant to flow orderly in the device. The coolant flowing in from the liquid inlet 15, under the guidance of the first guide groove section 11 and the second guide groove section 12, after passing through multiple guide grooves, then flows out from the liquid outlet 14. The whole process is smooth and efficient, providing a reliable cooling guarantee for the normal operation of the water-cooled plate.

[0047] Of course, the present invention may also have many other embodiments. Based on this embodiment, all other embodiments obtained by those of ordinary skill in the art without any creative work fall within the scope of protection of the present invention.
