Description

Technical Field

[0001] This invention relates to an integrated air-cooled radiator performance testing device, belonging to the technical field of testing devices. Background Technology

[0002] With the rapid development of electronic technology, electronic devices are continuously evolving towards miniaturization, high frequency, high integration, and high performance. During this process, the heat generated by electronic devices increases significantly. If heat cannot be dissipated in time, it will seriously affect their performance and lifespan. Therefore, heat sinks, as the core component for heat dissipation in electronic devices, have become crucial for ensuring their normal operation. To accurately determine whether a heat sink can achieve the expected heat dissipation effect, systematic testing is essential. Through testing, the heat dissipation capacity of the heat sink in real-world application scenarios can be effectively verified, providing reliable data support for the stable operation of electronic devices and further promoting the in-depth development and application of electronic devices in high-performance fields. To address this, the industry has developed relevant testing devices. For example, Chinese invention patent CN106323663A discloses a radiator testing platform and system, specifically including a support plate for supporting the radiator, two parallel side plates, a fan assembly, and at least one cover plate. The support plate is fixed between the two side plates; the cover plate is fixed between the two side plates, and the support plate, side plates, and cover plate form an accommodating space for accommodating the radiator; the fan assembly is installed at the ends of the two side plates for dissipating heat from the radiator; the cover plate has a hollow portion for placing the heat-generating device and for covering the radiator. This testing device places the heat-generating unit directly above the radiator to test its heat dissipation performance. However, because the two are in complete contact, the heat from the heat-generating unit may not be effectively conducted to the radiator, leading to testing errors and preventing an effective test of the radiator's performance.

[0006] The aforementioned integrated air-cooled radiator performance testing device includes a variable diameter tube between the mixing mechanism and the stabilizing mechanism; a humidity sensor is provided on the testing platform, with the sensor's probe extending into the variable diameter tube.

[0007] The aforementioned integrated air-cooled radiator performance testing device includes a second body, which contains multiple sets of first mixing units and multiple sets of second mixing units, arranged sequentially and at intervals.

[0008] The aforementioned integrated air-cooled radiator performance testing device comprises a first mixing unit consisting of multiple layers of first guide groups, with adjacent first guide groups arranged vertically; each first guide group consists of multiple equidistantly distributed first guide plates, the wide surface of which is inclined on a horizontal plane, with the first guide plate in the middle region being the longest and gradually shortening towards both sides; the second mixing unit consists of multiple layers of second guide groups, with adjacent second guide groups arranged vertically; each second guide group consists of multiple equidistantly distributed fourth guide plates, the wide surface of which is inclined on a vertical plane, with the fourth guide plate in the middle being the longest and gradually shortening towards both sides.

[0009] The aforementioned integrated air-cooled radiator performance testing device forms a first gas channel between the first guide plates in the same first guide group; the first gas channels of adjacent first guide groups flow perpendicularly to each other and are interconnected; a second gas channel is formed between the fourth guide plates in the same second guide group; the second gas channels of adjacent second guide groups flow perpendicularly to each other and are interconnected; the first gas channel is connected to the second gas channel whose end is located on the same horizontal plane.

[0011] The aforementioned integrated air-cooled radiator performance testing device includes a first heat dissipation substrate, on which multiple inner fin units are linearly distributed. Each inner fin unit is composed of multiple inner fin blocks. The inner fin blocks are oriented and have through slots inside, the orientation of which is consistent with the arrangement direction of the inner fins. The adjacent inner fin blocks are staggered and spaced apart by one, and are located in the same vertical plane.

[0012] The aforementioned integrated air-cooled radiator performance testing device includes a second heat dissipation base plate, on which multiple fourth guide plates are horizontally arranged, and an air-cooling channel is formed between the fourth guide plates, the second heat dissipation base plate, and the fourth body.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In this invention, the two sides of the fourth body in the workpiece testing mechanism are connected to a flow stabilizing mechanism and an air outlet pipe, respectively. A regulated power supply heats the evaporation section of the workpiece testing mechanism via a heating element, simulating the heating of a heat source. Then, a controllable air temperature supply mechanism is activated, controlling the airflow speed and temperature and delivering the air to a mixing mechanism. This mixing mechanism turbulently mixes the airflow during its flow, homogenizing the airflow temperature. The airflow with a stable temperature is then delivered to the flow stabilizing mechanism, which rectifies the airflow to ensure a smooth and directional flow. The working fluid flows through the condensation section of the workpiece testing mechanism, allowing direct contact between the working fluid in the evaporation section and the heating tube. This causes the working fluid to vaporize and rise into the condensation chamber, where it contacts the inner fins of the heat sink. The inner fins conduct heat to the outer fins, cooling the working fluid. The cooled and liquefied working fluid then flows back into the evaporation chamber. A first thermocouple temperature measuring network detects the temperature of the airflow entering the workpiece testing mechanism, a second thermocouple temperature measuring network detects the temperature of the airflow after it passes through the mechanism, and a third thermocouple temperature measuring network detects the temperature of the working fluid. These data are collected, processed, and analyzed to assess the heat transfer performance of the workpiece testing mechanism. Therefore, this invention achieves accurate evaluation of the heat transfer performance of a radiator through simulation of actual thermal load environments, precise cooling airflow control, and multi-faceted temperature monitoring, offering the advantage of high measurement accuracy.

[0015] 2. In this invention, after the airflow enters the mixing mechanism, it will sequentially circulate through the first mixing unit and the second mixing unit. When entering the first mixing unit, the airflow flows along the first gas channel formed by the first guide plate. At the same time, because the flow directions of the first gas channels of adjacent first guide groups are perpendicular to each other and connected, the high-temperature airflow and the low-temperature airflow collide during the flow, so that the two are fully mixed. Then, it enters the second gas channel of the second mixing unit. In the second gas channel, the airflow continues to flow and collide. During the process of sequentially circulating through the first mixing unit and the second mixing unit, the flow direction of the airflow is forced to change repeatedly, further making the high-temperature airflow and the low-temperature airflow fully mixed, thereby greatly reducing the temperature difference of the airflow and achieving a high degree of uniformity of the outlet air temperature.

[0016] 3. In this invention, the flow stabilization mechanism consists of an array of vertically and horizontally staggered guide plates, forming a gridded flow stabilization channel. When airflow enters, the vertical second guide plate first divides the turbulent airflow into multiple vertical airflow bundles, suppressing lateral disturbances; subsequently, the horizontally positioned third guide plate further directs the airflow to the horizontal direction, and the densely arranged flow stabilization channel homogenizes the airflow velocity. This orthogonal grid structure forces the airflow to move along the channel axis when passing through, eliminating airflow rotation and pulsation. At the same time, the smooth surface of the guide plates reduces frictional resistance, ultimately allowing the airflow to flow parallel and uniformly through the heat sink under test in a laminar state, ensuring the stability and accuracy of heat exchange conditions during the test.

[0017] 4. In this invention, by changing the number of the first mixing unit, the number of the second mixing unit, the number of the first guide group, the number of the second guide group, and the number of the second guide plate and the third guide plate in the flow stabilizing unit, the heat transfer performance test of workpiece testing mechanisms of various specifications and different structures can be adapted. At the same time, the mixing mechanism can be connected to multiple flow stabilizing mechanisms through the variable diameter pipe, so that the heat transfer performance test of multiple workpiece testing mechanisms can be performed simultaneously.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0028] Example: An integrated air-cooled radiator performance testing device, configured as follows Figure 1-8 As shown, the system includes a test platform 1, on which a controllable air temperature supply mechanism 2 is installed. The outlet of the controllable air temperature supply mechanism 2 is connected via a pipe to a mixing mechanism 3 located above the test platform 1. The outlet of the mixing mechanism 3 is connected to a flow stabilizing mechanism 4, and the outlet of the flow stabilizing mechanism 4 is connected to a workpiece testing mechanism 5. The outlet of the workpiece testing mechanism 5 is connected to an outlet pipe 6. The outlet of the flow stabilizing mechanism 4 is equipped with a first thermocouple temperature measuring mesh 7, made of T-type thermocouple material, which can accurately measure the airflow temperature entering the workpiece testing mechanism 5. The inlet of the outlet pipe 6 is equipped with a second thermocouple temperature measuring mesh 8, also made of T-type thermocouple material, used to monitor the airflow temperature after passing through the workpiece testing mechanism 5. Figure 3 As shown, the workpiece testing mechanism 5 includes an evaporation section 50 and a condensation section 51, with the condensation section 51 positioned above the evaporation section 50; Figure 4As shown, the evaporation section 50 includes a first platform 52, which contains an evaporation chamber 53. A heating tube 54 is located at the bottom of the evaporation chamber 53. The first platform 52 has an inlet and an outlet on its side for adding or discharging working fluid into or out of the evaporation chamber 53. The condensation section 51 includes a fourth platform 55, which contains multiple condensing plates 66. Each condensing plate 66 contains a condensation chamber 67, the inner wall of which is covered with heat dissipation inner fins 56. Heat dissipation outer fins 57 are wrapped around the outside of the condensing plates 66, forming a cooling channel 58 between the heat dissipation outer fins 57 and the fourth platform 55. The lower end of the condensation chamber 67 is connected to the evaporation chamber 53. A third thermocouple temperature measuring network 59 is located on the rear side of the first platform 52. The third thermocouple temperature measuring network 59 also uses T-type thermocouple material, and its probe extends into the evaporation chamber 53. The test platform 1 is equipped with a thermal imager located in front of the workpiece testing mechanism 5. The thermal imager is used to capture the temperature changes of various parts of the workpiece testing mechanism 5. The two sides of the fourth body 55 in the workpiece testing mechanism 5 are connected to the flow stabilizing mechanism 4 and the air outlet duct 6, respectively. The heating tube 54 heats the evaporation section 50 of the workpiece testing mechanism 5 through a regulated power supply to simulate the heating of a heat source. Then, the controllable air temperature supply mechanism 2 is activated. The controllable air temperature supply mechanism 2 controls the air speed and air temperature and sends the air to the mixing mechanism 3. The mixing mechanism 3 can turbulently mix the air during the flow process, so that the airflow temperature is uniform. Then, the airflow with stable temperature is delivered to the flow stabilizing mechanism 4. The flow stabilizing mechanism 4 rectifies the airflow to ensure that it flows through the workpiece testing mechanism in a smooth and directional manner. The condensation section 51 of the test mechanism 5 allows the working fluid in the evaporation section 50 to directly contact the heating tube 54, causing the working fluid to vaporize and rise into the condensation chamber 67 and contact the inner heat dissipation fins 56. The inner heat dissipation fins 56 conduct heat to the outer heat dissipation fins 57, causing the working fluid to cool down. The cooled working fluid liquefies and flows back into the evaporation chamber 53. The first thermocouple temperature measuring network 7 detects the airflow temperature entering the workpiece test mechanism 5, the second thermocouple temperature measuring network 8 detects the airflow temperature after passing through the workpiece test mechanism 5, and the third thermocouple temperature measuring network 59 detects the temperature of the working fluid. These data are collected and processed to analyze the heat transfer performance of the workpiece test mechanism 5.

[0029] Preferably, such as Figure 1As shown, the controllable air temperature supply mechanism 2 includes a constant temperature reaction cabinet 20 and a fan 21 installed below the test platform 1. The constant temperature reaction cabinet 20 is a conventional component that can be obtained commercially. It mainly heats or cools the circulating liquid in the pipeline through a built-in heating tube and a compressor, and then makes it flow in a closed loop through a built-in circulating pump. The fan 21 is equipped with a flow valve on the pipeline connected to the outside. The flow valve is used to detect the air volume entering the system. The air outlet of the fan 21 is connected to a gas-liquid heat exchanger 22 through a pipeline. The gas-liquid heat exchanger 22 is a conventional component that can be obtained commercially. It has a liquid passage pipe and a gas passage pipe inside, which are close to each other but isolated from each other, so that the circulating liquid heated by the constant temperature reaction cabinet 20 can heat or cool the air blown out by the fan 21. The inlet and outlet of the gas-liquid heat exchanger 22 are connected to the constant temperature reaction cabinet 20 through pipelines. The air outlet of the gas-liquid heat exchanger 22 is connected to the air inlet of the mixing mechanism 3 through a pipeline. The test platform 1 is equipped with a control panel and a working condition host. The control panel is used to control the fan speed 21, the heating temperature of the heating element 56, and the heat exchange temperature of the constant temperature reaction chamber 20. The working condition host is used to detect various data during the test. Furthermore, the test platform 1 is equipped with a monitor and an operating keyboard and mouse. The various parameters received by the working condition host are displayed on the monitor, and the working condition host can be operated by the keyboard and mouse. The controllable air temperature supply mechanism 2 delivers air to the gas-liquid heat exchanger 22 through the fan 21. The heat exchange temperature of the gas-liquid heat exchanger is controlled by the constant temperature reaction chamber 20, thereby controlling the air temperature entering the flow stabilizing mechanism 4. This allows the constant temperature reaction chamber 20 to adjust different air temperatures, simulating the heat transfer performance test of the radiator under different real-world conditions.

[0030] Preferably, such as Figure 1 and 2 As shown, a variable diameter pipe 9 is provided between the mixing mechanism 3 and the stabilizing mechanism 4; a humidity sensor 10 is provided on the test platform 1. In this embodiment, the humidity sensor 10 is a humidity sensor of model SHT35-DIS-B. The detection end of the humidity sensor 10 extends into the variable diameter pipe 9. The humidity sensor 10 detects the humidity of the airflow, thereby calculating the fog point and preventing fogging inside the gas-liquid heat exchanger 22. Furthermore, the variable diameter pipe 9 has one air inlet and multiple air outlets, so that the air outlet end of the variable diameter pipe 9 can be connected to multiple stabilizing mechanisms 4 and workpiece testing mechanisms 5, thereby enabling simultaneous testing of the heat transfer performance of multiple workpiece testing mechanisms 5. At the same time, the variable diameter pipe 9 can change its size to adapt to workpiece testing mechanisms 5 with different structural sizes.

[0031] Preferably, such as Figure 7As shown, the mixing mechanism 3 includes a second platform 30, within which multiple sets of first mixing units 31 and multiple sets of second mixing units 34 are arranged sequentially at intervals. The number of first mixing units 31 and second mixing units 34 can be adjusted according to requirements. In this embodiment, there are two sets of each type of mixing unit. Simultaneously, the number of first guide groups 32 in the first mixing unit 31, the number of second guide groups 35 in the second mixing unit 34, the number of first guide plates 33 in the first guide group 32, and the number of fourth guide plates 36 in the second guide group 35 can be adjusted according to requirements, thereby accommodating workpiece testing mechanisms 5 of different sizes. In this embodiment, the first mixing unit 31 is composed of eight layers of first guide groups 32, which are vertically arranged between adjacent first guide groups 32; the first guide group 32 is composed of seventeen equidistant first guide plates 33, the wide surface of the first guide plate 33 is inclined on the horizontal plane, the first guide plate 33 located in the middle area is the longest and gradually shortens to both sides; the second mixing unit 34 is composed of sixteen layers of second guide groups 35, which are vertically arranged between adjacent second guide groups 35; the second guide group 35 is composed of eleven equidistant fourth guide plates 36, the wide surface of the fourth guide plate 36 is inclined on the vertical plane, the fourth guide plate 36 located in the middle is the longest and gradually shortens to both sides. A first gas channel 37 is formed between the first guide plates 33 within the same first guide group 32; the first gas channels 37 of adjacent first guide groups 32 flow perpendicularly to each other and are interconnected; a second gas channel 38 is formed between the fourth guide plates 36 within the same second guide group 35; the second gas channels 38 of adjacent second guide groups 35 flow perpendicularly to each other and are interconnected; the first gas channel 37 is connected to the second gas channel 38 whose ends are located on the same horizontal plane. After the airflow enters the mixing mechanism 3, it will cycle through the first mixing unit 31 and the second mixing unit 34 in sequence. When entering the first mixing unit 31, the airflow flows along the first gas channel 37 formed by the first guide plate 33. At the same time, because the flow directions of the first gas channels 37 of the adjacent first guide group 32 are perpendicular to each other and connected, the high-temperature airflow and the low-temperature airflow collide during the flow, so that the two are fully mixed. Then it enters the second gas channel 38 of the second mixing unit 34. In the second gas channel 38, the airflow continues to flow and collide. During the process of cycling through the first mixing unit 31 and the second mixing unit 34 in sequence, the flow direction of the airflow is forced to change repeatedly, which further makes the high-temperature airflow and the low-temperature airflow fully mixed, thereby greatly reducing the temperature difference of the airflow and achieving a high degree of uniformity of the outlet air temperature.

[0032] Preferably, such as Figure 8As shown, the flow stabilizing mechanism 4 includes a third platform 40, within which multiple vertically arranged second guide plates 41 are installed; multiple horizontally arranged third guide plates 42 are also installed within the third platform 40, intersecting with the second guide plates 41 to form a flow stabilizing channel 43. When airflow enters, the vertical second guide plates 41 first divide the turbulent airflow into multiple vertical airflow bundles, suppressing lateral disturbances; subsequently, the horizontally arranged third guide plates 42 further direct the airflow to the horizontal direction, and homogenize the airflow velocity through the densely arranged flow stabilizing channels 43. This orthogonal grid structure forces the airflow to move along the channel axis when passing through, eliminating airflow rotation and pulsation. At the same time, the smooth surface of the guide plates reduces frictional resistance, ultimately allowing the airflow to flow parallel and uniformly through the workpiece testing mechanism 5 in a laminar state, ensuring the stability and accuracy of heat exchange conditions during the testing process.

[0033] Preferably, such as Figure 5 and 6 As shown, the heat dissipation inner fin 56 includes a first heat dissipation substrate 60, on which multiple inner fin units 61 are linearly distributed. Each inner fin unit 61 is composed of multiple inner fin blocks 62. The inner fin blocks 62 are oriented in a certain direction and have through slots 63 inside, the orientation of which is consistent with the arrangement direction of the inner fins. Adjacent inner fin blocks 62 are staggered and spaced apart by one, and are located in the same vertical plane. As the heated and vaporized working fluid rises, it comes into contact with the inner fin blocks 62 and the first heat dissipation substrate 60 of the heat dissipation inner fin 56. Due to the through slots 63 on the inner fin blocks 62, the contact area between the inner fin blocks 62 and the working fluid is increased, accelerating the heat dissipation efficiency. The heat is then dissipated to the heat dissipation outer fin 57 through the inner fin blocks 62 and the first heat dissipation substrate 60, thereby achieving heat dissipation of the working fluid.

[0034] Preferably, such as Figure 4 As shown, the heat dissipation outer fin 57 includes a second heat dissipation substrate 64, on which a plurality of fourth guide plates 65 are horizontally arranged. A cooling channel 58 is formed between the fourth guide plates 65, the second heat dissipation substrate 64, and the fourth platform 55. The inner end face of the second heat dissipation substrate 64 receives heat conducted from the heat dissipation inner fin 56, and conducts the heat to the outer end face of the second heat dissipation substrate 64 and the fourth guide plates 36. The heat is then carried away by the airflow blown out from the flow stabilizing mechanism 4, thus completing the heat dissipation.

[0035] Working principle:

[0036] Installation: Install the workpiece testing mechanism 5 to be tested on the testing platform 1, and connect the two sides of the fourth body 55 to the flow stabilizing mechanism 4 and the air outlet pipe 6 respectively to complete the installation of the heat sink 58 to be tested.

[0037] Test: The heating tube 54 at the bottom of the evaporation chamber 53 is activated to heat the simulated heat source and heat the working fluid. The fan 21 draws ambient air into the gas-liquid heat exchanger 22, and the constant temperature reaction cabinet 20 controls the output of the target air temperature. Then, the airflow passes through the mixing mechanism 3 to achieve air temperature uniformity, and then flows through the heat exchanger 58 under test in a parallel and uniform manner through the flow stabilizing mechanism 4. At the same time, the first and second thermocouple temperature measuring networks monitor the inlet and outlet air temperatures respectively, and the third thermocouple temperature measuring network 55 collects the working fluid temperature in real time. All data during the test process are collected and processed by the operating host.
