Description

Technical Field

[0001] The embodiments of this utility model relate to the field of environmental testing equipment technology, and in particular to a three-chamber temperature shock environmental test chamber with a rotating air duct and air plate structure, used to simulate environments with rapid changes in high and low temperatures, and to test the reliability of products in industries such as electronics, automobiles, aerospace, and new energy. It is especially suitable for heavy-load samples, wired or power supply test scenarios. Background Technology

[0002] Traditional three-chamber temperature shock test chambers generally adopt a vertical layout, with a high-temperature zone at the top, a middle testing zone, and a low-temperature zone at the bottom. However, this layout has some core drawbacks:

[0003] From the perspective of space and load-bearing capacity, vertical structures are difficult to expand into large testing areas. When heavy-duty samples (such as large industrial equipment, commercial vehicle battery packs, and large-size circuit boards) are moved in, they are easily restricted by height and load-bearing structure, resulting in difficulties in sample loading and high risks to equipment load.

[0004] In terms of site adaptability, due to the high height of the equipment (usually ≥4m), the requirements for the floor height and load-bearing capacity of the installation site are strict, making it difficult for small and medium-sized enterprises or old factories to deploy it.

[0005] In terms of testing scenarios, the frequent movement of the sample stage in a vertical layout makes it easy for cables to become tangled and pulled during wired tests, such as monitoring internal signals of the sample or providing continuous power, which can compromise the stability of the test.

[0006] Although existing technologies have attempted to optimize the structure, they have not solved the coordination issues of horizontal space utilization, heavy load adaptation, and wired testing compatibility. Utility Model Content

[0043] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0044] The first embodiment of this utility model relates to a rotating structure 4 for an air duct baffle, such as... Figure 1 and Figure 4 As shown, it includes:

[0045] In this embodiment, a dual-axis linkage rotating structure 41 is provided on the air duct air plate rotating structure 4;

[0046] A cylinder transmission system 42 is connected to one side of the dual-axis linkage rotary structure 41; the cylinder transmission system 42 drives the dual-axis linkage rotary structure 41 to operate and switch the dual-axis linkage rotary structure 41 on and off, ensuring that the rotation response time of the air vane 413 is ≤1.5s. The rapid opening and closing and precise control of the rotatable air vane 413, compared with the traditional platform translation structure, shortens the temperature conversion time by 20%, and the airflow introduction is more rapid and uniform, the temperature uniformity control is more superior, and the temperature shock efficiency is improved.

[0047] In this embodiment, a cylinder transmission system 42 is connected to one side of the dual-axis linkage rotary structure 41. The cylinder transmission system 42 drives the dual-axis linkage rotary structure 41 to operate and switch the dual-axis linkage rotary structure 41 on and off, ensuring that the rotation response time of the air vane 413 is ≤1.5s. The rapid opening and closing and precise control of the rotatable air vane 413, compared with the traditional platform translation structure, shortens the temperature conversion time by 20%, and the airflow introduction is faster and more uniform, the temperature uniformity control is better, and the temperature shock efficiency is improved, solving the technical problem of slow air vane rotation response time in the prior art.

[0048] To achieve the above-mentioned technical effects, such as Figure 1 and Figure 4 As shown, the cylinder transmission system 42 includes:

[0049] A base 421 is provided on the cylinder transmission system 42. The base 421 serves as a structural support, capable of bearing the weight of the cylinder 422 and preventing vibration and displacement.

[0050] A cylinder 422 is movably connected to the base 421 by a pin 423. The cylinder 422 can quickly drive the wind vane 413 to rotate, with a rapid response.

[0051] A piston connecting block 424 is fixedly connected to the other side of the cylinder 422. The piston connecting block 424 plays the role of power transmission.

[0052] The piston connecting block 424 is movably connected to the connecting block 411 via the pin 425. This movable connection allows the piston connecting block 424 to flexibly drive the connecting block 411 to rotate, enabling the air vane 413 to be precisely positioned at different angles, thus meeting the requirements of the temperature shock test for rapid and accurate temperature conversion.

[0053] To achieve the above-mentioned technical effects, such as Figure 1 and Figure 4 As shown, the dual-axis linkage rotary structure 41 includes:

[0054] On the other side of the piston connecting block 424, the connecting block 411 is movably connected by a pin 425. This movable connection allows the piston connecting block 424 to flexibly drive the connecting block 411 to rotate, so that the air plate 413 can be accurately positioned at different angles, meeting the requirements of the temperature shock test for rapid and accurate temperature conversion.

[0055] The other end of the connecting block 411 is fixedly connected to the rotating shaft 412. When the first fan 6 and the second fan 7 are running, the connecting block 411 will transmit power to the rotating shaft 412. The rotating shaft will start to rotate under the action of power, thereby driving the air plate 413 connected to the rotating shaft 412 to rotate. The rotating shaft 412 can also provide a fixed central axis for the rotation of the air plate 413. The fixed connection between the connecting block 411 and the rotating shaft 412 makes the air plate 413 move around the central axis during rotation, avoiding the air plate 413 from shaking or deviating during rotation, and ensuring the accuracy and stability of the air plate rotation.

[0056] The rotating shaft 412 fixes the connecting block 411 to the air plate 413. The air plate 413 can flexibly change the flow direction of the airflow in the air duct 5 according to the test requirements. When a high-temperature impact test is required, the air plate 413 rotates to allow the hot airflow in the high-temperature zone 1 to smoothly enter the intermediate test zone 3; while when a low-temperature impact test is required, the air plate 413 guides the cold airflow in the low-temperature zone 2 to the intermediate test zone 3, ensuring that the intermediate test zone 3 can accurately simulate different temperature environments.

[0057] Silicone rubber sealing strip 414 is inlaid around the periphery of the air plate 413. The rotating fit design of the air plate 413, together with the silicone rubber sealing strip 414, can effectively reduce the air leakage rate, improve the sealing performance and reliability, and also reduce the mechanical wear of the air plate 413 during the translation process, thus extending the service life of the equipment.

[0058] To achieve the above-mentioned technical effects, such as Figure 1 , Figure 3 and Figure 4 As shown, the air deflector 413 is hinged to the housing 10 via slewing bearings on both sides. These bearings provide a stable and flexible rotation support point for the air deflector 413, allowing it to rotate smoothly within the air duct 5. The slewing bearings also enable the air deflector to easily switch airflow directions between the high-temperature zone 1, the intermediate test zone 3, and the low-temperature zone 2, achieving rapid and accurate temperature conversion. Furthermore, utilizing the characteristics of the slewing bearings, the air deflector 413 can precisely adjust the rotation angle to control the volume of hot and cold air flowing into the intermediate test zone 3, improving the accuracy of the test results.

[0059] The second embodiment of this utility model relates to a three-chamber temperature shock environment test chamber with a rotating air duct and air plate structure, such as... Figure 1 and Figure 2 As shown, it includes:

[0060] The air duct and air plate rotating structure 4 is vertically installed in the high temperature zone 1. When the internal circulation is in progress, when the air plate 413 rotates to fit with the intermediate test zone 3, it is sealed by the silicone rubber sealing strip 414 (compression rate 25%, temperature resistance -80℃-200℃). At this time, the high temperature zone 1 or the low temperature zone 2 forms an independent internal circulation. The internal circulation mode stores energy in advance. Combined with the precise airflow control in the external circulation stage, the energy consumption is reduced by 15%-20% compared with similar equipment, which reduces energy consumption. The first fan 6 and the second fan 7 drive the airflow through the electric heating tube 11 or the cascade refrigeration system 9 and then continuously circulate in the closed space to quickly stabilize the internal temperature of the temperature zone.

[0061] The air duct and fan plate rotating structure 4 is horizontally installed in the low-temperature zone 2. When a temperature shock is required, one fan plate 413 quickly rotates and opens (rotation angle 90°, opening time ≤1.5s), while the other fan plate 413 closes instantly. The heat or cold energy pre-stored in the high-temperature zone 1 or the low-temperature zone 2 is rapidly introduced into the intermediate test zone 3 in the form of high-speed airflow through the large-diameter air duct 5. After the fan plate 413 opens, the system automatically switches to external circulation mode. The airflow introduced into the intermediate test zone 3 flows back to the high-temperature zone through the other side of the test zone air duct 5, forming a stable external circulation test to achieve rapid temperature shock of the sample (temperature transition time ≤10s).

[0062] An intermediate test area 3 is set between the high temperature zone 1 and the low temperature zone 2. The high temperature zone 1, the low temperature zone 2 and the intermediate test area 3 form a box 10. The intermediate test area 3 is used to place the sample to be tested and provides a relatively closed and safe environment.

[0063] A first fan 6 is installed in the high-temperature zone 1. The first fan 6 can quickly switch the temperature and, together with the air plate 413, ensure uniform temperature and improve heat exchange efficiency.

[0064] A second fan 7 is installed in the low-temperature zone 2. The second fan 7 can promote the uniform distribution of cooling capacity, accelerate the temperature reduction rate, and realize airflow switching, which helps to maintain the stability and efficiency of the cascade refrigeration system 9 and ensure that the low-temperature zone 2 can continuously provide a stable low-temperature environment.

[0065] An air duct 5 is set inside the three-chamber temperature shock environment test chamber with a rotating air duct and air plate structure. The air duct 5 provides a clear flow path for the hot air and cold air generated in the high temperature zone 1 and the low temperature zone 2.

[0066] The three-chamber temperature shock environment test chamber with a rotating air duct and air plate structure is arranged horizontally; the high temperature zone 1 and the low temperature zone 2 are symmetrically arranged on both sides of the three-chamber temperature shock environment test chamber with a rotating air duct and air plate structure to construct an independent temperature environment for conducting temperature shock environment tests.

[0067] In this embodiment, the three-chamber temperature shock environment test chamber with a rotating air duct and air plate structure is horizontally arranged. The high-temperature zone 1 and the low-temperature zone 2 are symmetrically arranged on both sides of the three-chamber temperature shock environment test chamber with the rotating air duct and air plate structure to construct an independent temperature environment for temperature shock environment testing. This solves the technical problems in the prior art, such as the difficulty in expanding the test area with a vertical structure, the difficulty in loading samples due to height and load-bearing structure constraints when moving heavy samples, the high equipment height, the stringent requirements for the floor height and load-bearing capacity of the installation site, the difficulty in deploying in small and medium-sized enterprises or old factories, and the frequent movement of the sample stage under the vertical layout, which leads to the easy tangling and pulling of cables during wired testing, thus compromising the stability of the test.

[0068] To achieve the above-mentioned technical effects, such as Figure 1 As shown, the high-temperature zone 1 and the low-temperature zone 2 are independently temperature controlled; the temperature of the high-temperature zone 1 is ≤200℃, and the temperature of the low-temperature zone 2 is ≥-70℃, which meets the requirements of high and low temperature sources for temperature shock.

[0069] To achieve the above-mentioned technical effects, such as Figure 1 As shown, several temperature sensors 15 are installed in the air duct 5. The temperature sensors 15 can monitor the airflow temperature in each area, capture dynamic temperature changes, and provide detailed temperature data for the experiment. The temperature sensors 15 can also dynamically adjust the rotation speed of the air vane 413, the speed of the first fan 6 and the second fan 7, and the heating / cooling power to ensure efficient and stable temperature shock process.

[0070] To achieve the above-mentioned technical effects, such as Figure 1 As shown, an electric heating tube 11 is installed in the high-temperature zone 1; the electric heating tube 11 adopts a finned heat dissipation structure to improve heat exchange efficiency; a cascade refrigeration system 9 is installed in the low-temperature zone 2, which is composed of high-temperature stage and low-temperature stage compressors working together to ensure sufficient cooling capacity under the condition of -70℃.

[0071] To achieve the above-mentioned technical effects, such as Figure 1 As shown, the intermediate test area 3 is fixed with a height of ≤0.5m above the ground, facilitating direct sample loading by forklifts, pallet jacks, and other handling equipment. Heavy-duty samples (load capacity ≥2000kg) can be easily moved in. The floor of the intermediate test area 3 is welded from stainless steel plates and covered with an anti-slip and wear-resistant coating to enhance load-bearing capacity and sample placement stability. A steel frame 16 and an anti-slip platform 8 are installed in the intermediate test area 3, with a load-bearing strength ≥5000kg / ㎡. Combined with the ultra-low height (≤0.5m) above the ground, forklifts can directly push heavy-duty samples into the chamber. The high-load-bearing test area and low platform design significantly increase the upper limit of the sample size that the equipment can test, meeting the testing requirements of large components. The steel frame 16 adopts a truss structure internally, and the stress distribution is optimized through finite element analysis to reduce the overall weight while ensuring structural strength.

[0072] To achieve the above-mentioned technical effects, such as Figure 1 and Figure 3 As shown, several first fans 6 are arranged on one side of the top surface of the housing 10, and several second fans 7 are arranged on the other side of the top surface of the housing 10.

[0073] The operation mode of this utility model is as follows: Figure 5 As shown, Figure 5 The airflow paths in the internal circulation mode and the temperature shock (external circulation) mode are illustrated. The temperature shock test procedure is as follows:

[0074] During the preparation phase, the external circulation fan is closed and the internal circulation fan is opened, meaning both fan panels are rotated to fit and seal against the middle test area. The high-temperature zone is heated to the target temperature (e.g., 150℃) and the low-temperature zone is cooled to the target temperature (e.g., -40℃). During this phase, each temperature zone operates independently in internal circulation until the temperature stabilizes. The system monitors the temperature of each zone in real time. When the temperature approaches the target value, the heating / cooling power is automatically adjusted, and the system enters the heat preservation phase.

[0075] During the testing phase, the sample is placed in the intermediate testing area. The control system issues a command, and one side air deflector (such as the high-temperature zone deflector) rapidly rotates and opens, while the low-temperature zone deflector instantly closes. The stored hot airflow from the high-temperature zone is then rapidly introduced into the intermediate testing area. After a set time, the high-temperature zone deflector closes, and the low-temperature zone deflector opens, allowing cold airflow into the intermediate testing area, completing one temperature shock cycle. The number of cycles, the duration of each stage, and the timing of the deflector actions can all be set through the control system program. During the temperature shock process, a wind speed sensor monitors the wind speed within the duct in real time. If the wind speed is abnormal, the system automatically adjusts the fan speed to ensure stable airflow. A temperature sensor collects temperature data from the testing area every 0.5 seconds, generating a temperature change curve for user analysis.

[0076] The cable is routed to the sample via a side channel in the testing area. This channel is equipped with sealing rubber components to ensure the chamber's airtightness. For high-current power supply tests, heat sinks are also installed within the channel to prevent the cable from overheating. A comprehensive cable management system supports long-term power-on testing and real-time data acquisition for electronic equipment.

[0077] During the heavy-load sample loading stage, a forklift is used to push the heavy-load sample (such as a 1.5t automotive battery pack) into the chamber along the ground track in the test area. The platform has a low ground clearance (≤0.5m), eliminating the need for additional lifting equipment and reducing loading time by more than 50%. Before loading, scratch-resistant and wear-resistant mats are laid on the test area floor to protect the sample and platform surface. A laser positioning system is used to ensure that the sample is accurately placed in the center of the test area. The high-load test area and low platform design significantly increase the upper limit of the sample size that the equipment can test, meeting the testing needs of large components.

[0078] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
