Description

Technical Field

[0001] This invention specifically relates to a rapid testing system and method for the thermal performance of heat pipe radiators, belonging to the field of air-cooled phase change heat dissipation technology. Background Technology

[0002] With the continuous development of power electronics technology, the problem of heat dissipation for electronic components with high heat flux density has become increasingly prominent. Traditional air-cooling technology can no longer meet the needs of use. The air-cooling route of combining phase change heat pipes with finned heat sinks has been increasingly promoted and applied in new energy products such as energy storage due to its advantages of high heat exchange efficiency and relatively low cost. The addition of heat pipes has improved the overall heat dissipation capacity, but it has also introduced new potential failure risks. In particular, heat sinks that take into account the heat dissipation of multiple components have put forward higher requirements for the thermal performance management of heat pipe heat sinks. Therefore, it is particularly important to inspect the condition of heat pipes and heat sinks. When unscreened or with unreasonable screening methods, defective heat pipe heat sinks enter the use stage, which has a huge impact on the stability of subsequent applications. At the same time, with the large-scale use of heat pipe heat sinks, the efficiency of inspection has also become very important. There is a clear demand for automated inspection, online judgment of inspection results, and intelligent analysis of fault causes.

[0003] Patent CN117816565B discloses a method and equipment for detecting the temperature rise of heat pipe radiators. By placing the heat pipe radiator in an air duct simulating its working environment, accurate data can be obtained, ensuring the performance of the heat pipe radiator. However, this only simulates the cooling environment; the condition of the heat pipes is not effectively tested and determined. For radiators with multiple heat pipes, the test results cannot accurately reflect the actual condition of the radiator, posing a risk of defective radiators being mistakenly judged as qualified and entering the market. This patent uses a flipping testing table and a lifting trolley to clamp, flip, and transport the heat pipe radiators, reducing the labor intensity of testing personnel and shortening the testing time. However, the overall testing method is limited to the flexible handling of mechanical operations, with a low degree of automation and intelligence. For large-scale testing, the workload remains significant, and the testing efficiency is low.

[0004] Patent CN119714956A discloses a heat pipe radiator testing device, which solves the problem of low testing accuracy and poor reliability caused by poor coordination of the testing mechanism when testing specific heat pipes of heat pipe radiators with a large number of heat pipes and complex arrangement. Both patents CN117816565B and CN117816565A attempt to solve the problem of radiator thermal performance testing by optimizing the mechanical structure, but the overall testing methods have not been significantly improved and cannot solve the current predicament.

[0005] Patent CN117816565B discloses a heat exchanger tube testing and sorting device. This invention adopts an integrated structure, which can continuously and automatically test, print labels, and sort silicon carbide tubes, achieving integrated operation and improving production efficiency. However, the test results and accuracy only meet the requirements for heat pipe consistency screening. Patent CN221593966U discloses a heat pipe performance testing device. This device uses an induction coil to heat the heat pipe to be tested, eliminating the need for manual testing. It has a simple structure and achieves the purpose of intelligent testing. Like patent CN117816565B, both technical routes limit the test object to individual heat pipes, and the application principle of the testing equipment limits the universality of the test object material. Neither of the two patented technical solutions has the conditions for direct application in the testing of heat pipe radiators and the performance of heat pipes on their surfaces. Summary of the Invention

Under the action of the sensor limiting assembly, the pressure plate moves closer to the heat pipe condenser end of the heat pipe radiator, descends through the second pneumatic linkage mechanism, and abuts against the pressure plate, so that the heat pipe condenser end temperature monitoring sensor is attached to the condenser end of the heat pipe radiator to monitor its temperature.

[0024] In the first technical solution mentioned above, the second pneumatic linkage mechanism includes a second cylinder and an end plate. The second cylinder is electrically connected to the connection end corresponding to the electrical control device. The piston end of the second cylinder is provided with an end plate that can abut against or separate from the press plate.

The two ends of the limiting guide rail are respectively connected to the piston of the third cylinder through a connecting plate, and the pressing plate is provided in the limiting guide rail.

[0026] To achieve the above objectives, the second technical solution of the present invention is: a test method for rapid detection of the thermal performance of a heat pipe radiator, the innovation of which lies in: including the aforementioned rapid detection system for the thermal performance of a heat pipe radiator, and the specific test steps are as follows:

[0032] Conversely, based on the difference ΔT between the two... 0-N_actual|N=(1~N) The electrical control device performs a logical judgment against the acceptable range value; if ΔT 0-N Not meeting the acceptable range (ΔT) min ΔT max If the value is 0, the test will fail.

[0033] In the second technical solution mentioned above, in step a, based on the heat dissipation of the heat pipe radiator under test and the installation requirements of the electronic components, the rated pressure force P0 and heating power Q0 required by the simulated heating device are determined, and based on the operating characteristics of the heat pipe radiator under test and the electronic components, the acceptable fluctuation range (P0, Q0, Q0, Q0) of the two parameters is determined. min P max ), (Qmin Q max Based on the thermal characteristics of the heat pipe radiator under test and the heating power Q0, determine the evaporator end temperature T of the heat pipe. hot With respect to the condenser end temperature T cold and the permissible limit T of the usage environment hot_max T cold_min .

[0034] In the second technical solution mentioned above, in step b, if the fluctuation range of each monitored temperature is within ±0.5℃ after 1 to 2 minutes, it is considered that the test operation is stable and the test is qualified.

Detailed Implementation

[0069] The present invention will be further described below with reference to the accompanying drawings and the given embodiments, but is not limited thereto.

[0070] Example 1

[0076] The condenser end temperature monitoring mechanism 15 is mounted on the main body 11 and is located close to the condenser end of the heat pipe radiator to be tested.

[0077] The heat pipe condenser end temperature monitoring sensor 16 is attached to the surface of the radiator condenser end temperature monitoring mechanism 15. Under the action of the radiator condenser end temperature monitoring mechanism 15, the heat pipe condenser end temperature monitoring sensor 16 monitors the condenser end temperature of the heat pipe radiator.

The heat pipe evaporator end temperature monitoring sensor 14 and the heat pipe condenser end temperature monitoring sensor 16 are electrically connected to the corresponding connection terminals of the data acquisition unit. The data acquisition unit receives the data sent by the temperature monitoring sensors, processes it, and sends it to the CPU. The first cylinder, the second cylinder, and the third cylinder are electrically connected to the corresponding connection terminals of the cylinder control module. The resistance heating block 132 is electrically connected to the corresponding connection terminal of the CPU.

[0080] Furthermore, the operating parameters of the rapid thermal performance detection unit 1 are input through the human-machine interface of the electrical control device 2. The CPU collects the actual operating monitoring values ​​of all parameters (including data sent by the temperature monitoring sensor, the actual pressure value applied by each cylinder, and the actual heat power applied by the resistance heating block), and performs logical judgment processing with the parameter values ​​set in the CPU beforehand, and outputs the test validity and the thermal performance qualification information of the heat pipe radiator under test.

[0081] Furthermore, such as Figure 3 As shown, to make the main structure simpler and more compact, and to facilitate adaptation to different types and specifications of heat pipe radiators, the main body 11 is a frame structure, which includes a fixed crossbeam frame 111, a workbench 112, and a movable gantry frame 113. The fixed crossbeam frame 111 is fixedly connected to the workbench 112 and is located at the bottom of the workbench 112. The movable gantry frame 113 is adjustablely mounted on the workbench 112 and is detachably connected to it.

[0082] The heat pipe radiator under test is mounted on the heat dissipation module 12 on the workbench 112, and the simulated heating device 13 and the radiator condenser end temperature monitoring mechanism 15 are both fixed on the mobile gantry frame 113.

[0084] Furthermore, such as Figure 3 As shown, in order to facilitate support of the workbench and facilitate transportation, the fixed crossbeam frame 111 is composed of multiple crossbeams, and the multiple crossbeams are evenly distributed at the bottom of the workbench 112.

Under the action of the sensor limiting assembly, the pressure plate 152 moves closer to the heat pipe condenser end of the heat pipe radiator, descends through the second pneumatic linkage mechanism 151, and abuts against the pressure plate 152, so that the heat pipe condenser end temperature monitoring sensor 16 is attached to the condenser end of the heat pipe radiator to monitor its temperature.

[0091] Furthermore, such as Figure 6 As shown, in order to facilitate the application of pressing force to the press plate through the pneumatic linkage mechanism, the second pneumatic linkage mechanism 151 includes a second cylinder 1511 and an end plate 1512.

At the same time, the press plate 152 is provided inside the limiting guide rail 154.

[0093] Example 2

[0094] like Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, a test method for rapid thermal performance testing of a heat pipe radiator includes the aforementioned rapid thermal performance testing system for heat pipe radiators. The specific test steps are as follows:

[0095] Step a, in the electrical control device 2, the rated pressure force P0 and heating power Q0 required by the simulated heating device 13, as well as the acceptable fluctuation range of the two parameters (P0, Q0, and Q0) are preset. min P max ), (Q min Q max ),

[0096] In the electrical control device 2, the rated pressure applied by the radiator condenser end temperature monitoring mechanism 15 and the acceptable fluctuation range are preset to P'0, (P ... min , P' max ),

[0097] The heat pipe evaporator temperature T is set in electrical control device 2. hot With respect to the condenser end temperature T cold and the permissible limit T of the usage environment hot_max T cold_min And the temperature difference ΔT0 between the two and its acceptable range (ΔT min ΔT max ),

[0098] Step b: Install the heat pipe radiator under test onto the heat dissipation module 12, and input the pressing force P of the simulated heating device 13 through the electrical control device 2. 0-N|N=(1~N) and heating power Q 0-M|M=(1~M) The pressing force P' of the radiator condenser end temperature monitoring mechanism 15 0-N|N=(1~N) Simultaneously collect the actual applied values ​​P of three parameters. actual-N|N=(1~N) Q actual-M|M=(1~M) 、P' actual-N|N=(1~N)It performs a logical comparison with the pre-set acceptable range of corresponding parameters, and simultaneously collects the actual temperature value T monitored at the heat pipe evaporator end. hot-N_actual|N=(1~N) The actual temperature value T measured at the condenser end of the radiator cold-N_actual|N=(1~N) ,

[0099] If all monitored temperature fluctuations are within ±0.5℃, the test is considered stable and qualified.

[0100] Conversely, based on the difference ΔT between the two... 0-N_actual|N=(1~N) The electrical control device 2 performs a logical judgment against the acceptable range value. If ΔT 0-N Not meeting the acceptable range (ΔT) min ΔT max If the test fails, the test is deemed unsuccessful. ΔT 0-N_actual|N=(1~N) and ΔT 0-N The references are the same, the stated ΔT 0-N_actual|N=(1~N) This refers to the sum of multiple measuring points. For example, if there are 10 measuring points, the measured temperatures at each of the 10 measuring points correspond to... T1 , T2...T9 , T10 .

[0101] Furthermore, in step a, based on the heat dissipation of the heat pipe radiator under test and the installation requirements of the electronic components, the rated pressure force P0 and heating power Q0 required by the simulated heating device are determined, and based on the operating characteristics of the heat pipe radiator under test and the electronic components, the acceptable fluctuation range (P0, Q0, Q0, Q0, Q0) of the two parameters is determined. min P max ), (Q min Q max Based on the thermal characteristics of the heat pipe radiator under test and the heating power Q0, determine the evaporator end temperature T of the heat pipe. hot With respect to the condenser end temperature T cold and the permissible limit T of the usage environment hot_max T cold_min .

[0102] Furthermore, in step b, if the fluctuation range of each monitored temperature is within ±0.5℃ after 1 to 2 minutes, it is considered that the test operation is stable and the test is qualified.

[0103] Furthermore, step b also includes a thermal performance test notification for the heat pipe radiator under test, specifically:

[0104] ①When P actual-N|N=(1~N) ≥P max or P' actual-N|N=(1~N) ≥P' maxThe electrical control device 2 displays the message: "Test invalid. The thermal performance rapid detection device has too much pressure. Please stop operation and adjust the input value."

[0105] ②When P actual-N|N=(1~N) ≤P min or P' actual-N|N=(1~N) ≤P' min The electrical control device 2 displays the message: "Test invalid. The thermal performance rapid detection device has insufficient pressing force. It is recommended to stop operation and check whether the pressing surface and pneumatic linkage mechanism are abnormal."

[0106] ③When P min <P actual-N|N=(1~N) <P min , P' min <P' actual-N|N=(1~N) <P' max Q actual-M|M=(1~M) ≥Q max The electrical control device 2 displays the message: "Test invalid. The simulated heating device is applying too much power. Please stop operation and adjust the input value."

[0107] ④ When P min <P actual-N|N=(1~N) <P min , P' min <P' actual-N|N=(1~N) <P' max Q actual-M|M=(1~M) ≤Q min The electrical control device 2 displays the message: "Test invalid. The power applied by the simulated heating device is too low. Please stop operation. It is recommended to check the electrical wiring and adjust the input value."

[0108] ⑤ When P min <P actual-N|N=(1~N) <P min , P' min <P' actual-N|N=(1~N) <P' max Q min <Q actual-M|M=(1~M) <Q max ΔT 0-N_actual|N=(1~N) ≥ΔT max The electrical control device 2 displays the message: "The equipment is operating normally, but the thermal performance of the radiator is unqualified. Please isolate the equipment and confirm the heat exchange capacity and structural dimensions of the radiator heat pipes."

[0109] ⑥ When P min <P actual-N|N=(1~N) <P min , P' min <P' actual-N|N=(1~N) <P' max Q min <Qactual-M|M=(1~M) <Q max ΔT 0-N_actual|N=(1~N) >>ΔT max The electrical control device 2 displays the message: "The equipment is operating normally, but the thermal performance of the radiator is unqualified. Please isolate the equipment and confirm whether the heat pipes of the radiator have failed."

[0110] Among them, when ΔT 0-N_actual|N=(1~N) >> ΔT max In the sixth case ΔT 0-N_actual|N=(1~N) The actual value is much higher than in case ⑤. ΔT 0-N_actual|N=(1~N) ≥ ΔT max The limit value at that time, for example, if set ΔT max= 5 ℃, In the sixth case ΔT 0-N_actual|N=(1~N) Temperatures of 20°C or even higher;

[0111] ⑦ When P min <P actual-N|N=(1~N) <P min , P' min <P' actual-N|N=(1~N) <P' max Q min <Q actual-M|M=(1~M) <Q max ΔT 0-N_actual|N=(1~N) ≤ΔT min T hot-N_actual|N=(1~N) ≥T hot_max The electrical control device 2 displays the message: "The equipment is operating normally, but the thermal performance of the radiator is unqualified. Please isolate the device and confirm whether there is serious poor contact between the radiator base and the heat pipe."

The thermal performance of the radiator is pending. It is suspected that the heat pipe has reached the boiling limit. It is recommended to retest."

[0113] The heat pipe contains a refrigerant. Before the test starts, the refrigerant is in a liquid state. After the test starts, the resistance heating block 132 of the simulated heating device 13 works, and the refrigerant undergoes a phase change, changing from a liquid state to a gaseous state and flowing towards both ends of the heat pipe. Under the cooling effect of the external air, the refrigerant changes from a gaseous state to a liquid state and flows back under the action of gravity or siphon force, repeating the cycle. When the heat pipe reaches the boiling limit, it means that due to the excessive heat of the test heating, the refrigerant inside the heat pipe changes from a liquid state to a gaseous state and forms a completely gaseous state, and the phase change cycle process cannot be formed, resulting in a cumulative decrease in heat transfer efficiency.

[0114] ⑨ When P min <P actual-N|N=(1~N) <P min And P' min <P' actual-N|N=(1~N) <P' max Q min <Q actual-M|M=(1~M) <Q max ΔT min <ΔT 0-N_actual|N=(1~N) <ΔT max T hot-N_actual|N=(1~N) <T hot_max The electrical control device 2 displays the message: "The equipment is operating normally, the thermal performance of the radiator has been tested and is qualified. Please continue the process."

[0115] Furthermore, if the electrical control device 2 displays the message: "Equipment is operating normally, heat performance of the radiator is pending, heat pipe is suspected to have reached boiling limit, retesting is recommended," then the heating power should be immediately turned off and the device cooled to room temperature before retesting.

[0116] a) When Q min <Q actual-M|M=(1~M) <Q max ΔT 0-N_actual|N=(1~N) ≤ΔT min T hot-N_actual|N=(1~N) <T hot_max T cold-N_actual|N=(1~N) ≤T cold_min The electrical control device 2 displays the message: "Equipment is operating normally. The radiator retest is complete, but the performance is unqualified. Please isolate."

[0117] b) When Q min <Q actual-M|M=(1~M) <Q max ΔT 0-N_actual|N=(1~N) ≤ΔT min T hot-N_actual|N=(1~N) <T hot_max T cold-N_actual|N=(1~N) >T cold_minThe electrical control device 2 displays the message: "The equipment is operating normally. The retest of the heat sink is complete. The performance is considered qualified and can continue to be processed."

[0118] In summary, the beneficial effects of this invention are as follows:

[0119] 1. The detection system of the present invention is not only compact in structure and simple to install, but also convenient to operate and has high stability in operation;

[0120] 2. The detection system of the present invention adopts a modular frame structure, with a mobile gantry frame and a heat dissipation module installed on the heat pipe radiator to be tested. It is not only convenient for online adjustment and operation, but also can adapt to the testing needs of different types and specifications of radiators, making the detection highly versatile.

[0121] 3. The detection system of the present invention adopts an electronic control operation mode, which enables online input and one-click confirmation of the parameters that trigger the operation of the equipment. Before the test starts, the actual applied value is fed back and fine-tuned online to meet the allowable operating range of the heat pipe radiator under test, ensuring the effectiveness of the test and more closely resembling the actual working environment of the heat pipe radiator under test.

[0122] 4. The detection system of the present invention monitors and collects the operating parameters of all equipment and the heat sink under test in real time. The electrical control device performs logical operations on the monitored parameter information and gives the result of whether it is qualified or not. At the same time, the detection method can realize intelligent operation and predict the status of heat pipe heat sink and its surface heat pipe, so as to achieve the purpose of prompting information on the cause of abnormality, and achieve the purpose of efficient and accurate screening.

[0123] Therefore, this invention addresses the shortcomings of existing heat pipe radiator testing equipment, such as low intelligence in the operating mechanism, insufficient coverage of key parameters by the monitoring mechanism, and inadequate stability of the testing mechanism. These shortcomings prevent the equipment from fully reflecting the operating environment of the heat pipe radiator, leading to low accuracy in test results. Furthermore, the structure of the heat pipe testing equipment cannot fully simulate the working state of the heat pipes used in heat pipe radiators, and it cannot be directly applied to the thermal performance testing of heat pipe radiators. The technical solution provided by this invention enables the testing of heat pipe radiators and their thermal performance. It adopts a modular framework structure, introducing multiple testing modules, fully considering the influence of factors such as heat source power and pressure on the test results. It also takes into account the working state of similar heat pipes in different heat pipe arrangement schemes and their impact on the overall performance of the heat pipe radiator. The invention employs an electronically controlled operating mode and proposes a testing method, realizing online detection and result judgment, intelligent analysis of abnormal results, and comprehensively solving the need for automated testing. This improves both overall testing efficiency and detection accuracy.

[0124] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
