[0031] This disclosure aims to address the problems of existing high-temperature aging test cabinets, which typically involve arraying placement trays inside and placing test items within these trays. However, existing trays are often simply fixed inside the cabinet, leading to insecure placement and affecting test results. Furthermore, the trays remain too hot after testing, hindering immediate removal and impacting testing efficiency. Therefore, this disclosure proposes a high-precision high-temperature aging test cabinet. This cabinet utilizes heating wires within the heating chamber for efficient heat generation, combined with a heat insulation plate to reduce heat loss, a heat dissipation plate to ensure uniform temperature within the chamber, and a heat dissipation component to assist in temperature control and equipment cooling. The overall design improves test accuracy and reliability, providing a stable high-temperature environment for the test components, facilitating accurate performance evaluation and meeting diverse aging test requirements. Moreover, the coordinated action of the limiting plate, placement trays, fixing rods, and fixing arms ensures stable component positioning during high-temperature aging testing, preventing displacement caused by vibration or temperature changes from affecting test results. Meanwhile, in conjunction with the sliding door and fixing sleeve, it facilitates the quick installation and removal of components, improving testing efficiency, ensuring a smooth testing process, and enhancing the practicality and ease of operation of the test cabinet. Furthermore, the access handle, combined with the fixing tray, magnetic blocks, and magnetic grooves, allows for the secure attachment and removal of components, simplifying operation and effectively preventing component damage. The specially designed magnetic structure precisely fits the placement tray, ensuring a stable and reliable retrieval process. In addition, the fixing slot on one side of the sliding door facilitates the storage and retrieval device, optimizing the operating process and making it convenient for personnel to use.

[0032] like Figures 1 to 7 As shown, a high-precision high-temperature aging test cabinet includes a test cabinet body 1, a heating device 2, a fixing device 3, and a storage and retrieval device 4. The heating device 2 is installed around the test cabinet body 1 and is used to heat the inside of the test cabinet body 1 to complete the test. The fixing device 3 is installed inside the test cabinet body 1 and is used to fix the component to be tested, so as to cooperate with the test cabinet for testing. The storage and retrieval device 4 is installed on one side of the fixing device 3 and is used to remove the component after testing.

[0033] The heating wire 22 within the heating chamber 21 efficiently generates heat, while the heat insulation plate 23 reduces heat loss. The heat distribution plate 24 ensures uniform temperature within the chamber, and the heat dissipation component 25 assists in temperature control and equipment cooling. The overall design enhances testing accuracy and reliability, providing a stable high-temperature environment for the components under test, facilitating accurate performance evaluation and meeting diverse aging test requirements. Furthermore, the synergistic action of the limiting plate 31, placement tray 32, fixing rod 33, and fixing arm 34 ensures stable component positioning during high-temperature aging tests, preventing displacement caused by vibration or temperature changes from affecting test results. Simultaneously, its cooperation with the sliding door 11 and fixing sleeve 12 facilitates rapid component installation and removal, improving testing efficiency, ensuring a smooth testing process, and enhancing the practicality and ease of operation of the test cabinet. Additionally, the access handle 41, combined with the fixing tray 42, magnetic block 43, and magnetic groove 44, securely attracts and removes components, simplifying operation and effectively preventing component damage. The specially designed magnetic structure precisely fits the placement tray 32, ensuring a stable and reliable retrieval process. In addition, the fixed groove 13 on one side of the sliding door 11 facilitates the storage and retrieval device 4, optimizes the operation process, and makes it convenient for personnel to use.

[0034] like Figure 2 As shown, the heating device 2 includes a heating chamber 21, a heating wire 22, a heat insulation plate 23, a heat equalization plate 24, and a heat dissipation assembly 25. The heating chamber 21 is installed inside the test cabinet body 1 and is used to store the heating device 2. The heating wire 22 is installed inside the heating chamber 21 and is used to generate heat. The heat insulation plate 23 is installed on the outside of the heating chamber 21 and is used to insulate heat and prevent the outside of the test cabinet body 1 from overheating. The heat equalization plate 24 is installed on the inside of the heating chamber 21 and is used to evenly distribute heat, thereby ensuring that the component under test is heated evenly. The heat dissipation assembly 25 is installed inside the test cabinet body 1 and is used to dissipate heat using air ducts.

[0035] The heating chamber 21 is installed inside the test cabinet body 1, providing stable support and independent space for the heating components, facilitating centralized heat management. Heating wires 22 are installed inside the heating chamber 21 as the heat source, efficiently generating heat. The outer heat insulation plate 23 effectively prevents heat from diffusing to the outside, avoiding overheating of the test cabinet exterior, ensuring operational safety, and reducing energy consumption. The inner heat-dissipating plate 24 evenly distributes heat, ensuring uniform heating of the component under test during testing, improving test accuracy and reliability. The heat dissipation component 25 achieves precise heat dissipation through an air duct design, effectively regulating the internal temperature of the chamber, preventing equipment damage due to overheating, and extending its service life.

[0036] like Figures 1 to 4As shown, the heat dissipation component 25 includes a heat dissipation duct 251, heat dissipation holes 252, a heat dissipation fan 253, and an air outlet 254. The heat dissipation duct 251 is located between the test cabinet body 1 and the heating device 2, and is used to allow air to flow and thus dissipate heat. The heat dissipation holes 252 are arrayed inside the heat dissipation duct 251, and are used to allow air to enter the heat dissipation duct 251 to achieve heat exchange. A heat dissipation fan 253 is installed at one end of the heat dissipation hole 252, and is used to drive air into the heat dissipation duct 251. An air outlet 254 is provided at the other end of the heat dissipation duct 251, and is used to exhaust the air after heat exchange.

[0037] During operation, the cooling motor starts, drawing air through the cooling holes 252 into the cooling duct 251. The air then exchanges heat with the heating chamber and flows out from the outlet 254. The cooling duct 251, located between the test cabinet body 1 and the heating device 2, provides an efficient channel for heat exchange. The array of cooling holes 252 within the duct evenly introduces external air, ensuring thorough heat exchange with the hot air. A cooling fan 253, installed at one end of the cooling holes 252, actively drives the airflow to ensure efficient heat dissipation, while the outlet 254 at the other end smoothly exhausts the hot air that has undergone heat exchange. This forms a complete cooling cycle, effectively reducing the internal temperature of the test cabinet, preventing overheating, extending the equipment's lifespan, ensuring the stability of the testing process and the reliability of component performance, and meeting the stringent temperature control requirements of high-precision aging tests.

[0038] like Figure 4 As shown, the air outlet 254 is arranged at an upward angle. This upward arrangement primarily directs the hot air after heat exchange upwards, thus preventing injury to operators. This design cleverly utilizes the natural upward movement of hot air, avoiding the risk of burns that could occur if hot air were directly discharged downwards or horizontally, significantly improving the safety of the equipment. Simultaneously, the upward-angled air outlet 254 also helps hot air quickly diffuse into the surrounding environment, further improving heat dissipation efficiency and ensuring the temperature stability and reliability of the test cabinet during long-term operation.

[0039] like Figure 5 and Figure 7As shown, the fixing device 3 includes a limiting plate 31, a placement tray 32, a fixing rod 33, and a fixing arm 34. The limiting plate 31 is symmetrically installed in the heating cavity 21 and is used to limit the placement tray 32. The placement tray 32 is placed on the limiting plate 31 and is used to hold the component to be tested. The fixing rod 33 is provided on the limiting plate 31 for fixing and fixing the fixing arm 34. The fixing rod 33 is a hollow structure, and the fixing arm 34 is coaxially arranged inside the fixing rod 33. The fixing arm 34 is used to insert into the fixing rod 33 to fix the placement tray 32. The fixing arm 34 is fixedly connected to the placement tray 32.

[0040] During operation, the operator first pulls the placement tray 32 out of the limiting plate 31 and places the component to be tested inside. Then, the placement tray 32 is pushed into the limiting plate 31. At this time, the fixing arm 34 slides inside the fixing rod 33 to limit the placement tray 32.

[0041] The limiting plates 31 are symmetrically installed within the heating chamber 21, providing stable support and precise positioning for the placement tray 32. This ensures the placement tray 32 remains in place during testing, preventing displacement due to vibration or temperature changes. The placement tray 32 holds the components to be tested, and its cooperation with the limiting plates 31 facilitates the placement and removal of components. The ingenious combination of the fixing rod 33 and the fixing arm 34, utilizing the sliding mechanism of the fixing arm 34 inserted into the fixing rod 33, enables rapid fixing and release of the placement tray 32, ensuring simple, secure, and reliable operation.

[0042] like Figure 1 As shown, the test cabinet body 1 is provided with a movable door 11, which is used to control the opening and closing of the test cabinet body 1. An array of fixing sleeves 12 are installed on the movable door 11 for fixing. The fixing sleeves 12 are used to engage the placement tray 32 when the movable door 11 is closed, thereby further fixing the placement tray 32. The fixing sleeves 12 correspond to the position of the placement tray 32. The fixing sleeves 12 installed in the array on the movable door 11 correspond to the position of the placement tray 32. When the movable door 11 is closed, the placement tray 32 can be engaged in the fixing sleeves 12, thereby further fixing the placement tray 32, enhancing the stability of the placement tray 32 during the test, and preventing displacement of the placement tray 32 due to accidental vibrations or other factors, which would affect the test results.

[0043] like Figure 5 and Figure 7As shown, the access device 4 includes an access handle 41, a fixed tray 42, a magnetic block 43, and a magnetic groove 44. The fixed tray 42 is mounted on the access handle 41 to support the placement tray 32. The fixed tray 42 has a magnetic block 43 for adsorption, and the placement tray 32 has a magnetic groove 44 for engaging with the magnetic block 43. The magnetic block 43 engages with the magnetic groove 44 to fix the placement tray 32, allowing workers to remove the high-temperature placement tray 32. The magnetic block 43 precisely adsorbs into the magnetic groove 44 on the placement tray 32, and the fixed tray 42 firmly supports the placement tray 32, enabling workers to safely and conveniently remove the high-temperature placement tray 32, effectively avoiding direct contact with high-temperature components and reducing the risk of burns. Simultaneously, the stable engagement of the magnetic structure ensures stability during the retrieval process, preventing damage to components due to shaking, ensuring the integrity of the test components and the reliability of the test results, optimizing the operation process, and improving work efficiency.

[0044] like Figure 3 As shown, a fixed slot 13 for placing the storage and retrieval device 4 is provided on one side of the movable door 11. The fixed slot 13 provides a dedicated storage location for the storage and retrieval device 4, allowing it to be placed in an orderly manner when not in use, avoiding loss or damage caused by random placement, and improving the cleanliness and management efficiency of the equipment. On the other hand, the fixed slot 13 is located adjacent to the movable door 11, which makes it convenient for staff to quickly retrieve the storage and retrieval device 4 to remove components after testing, reducing the search and preparation time in the operation process, improving work efficiency, further optimizing the operation experience of the test cabinet, and enhancing the overall practicality of the equipment.

[0045] The overall working process is as follows: The operator operates the access handle 41 to contact the magnetic block 43 with the magnetic groove 44. At this time, the placement tray 32 is fixed with the fixed tray 42. After the operator places the component to be tested on the placement tray 32, the operator sends the placement tray 32 into the test cabinet body 1 and turns on the heating device 2 to start heating. At the same time, the cooling motor starts and drives the air to enter the cooling air duct 251 through the cooling hole 252. At this time, the air and the heating chamber complete heat exchange and flow out from the air outlet 254 to complete heat dissipation. After the test is completed, the operator operates the access handle 41 to contact the magnetic block 43 with the magnetic groove 44 and take out the high temperature placement tray 32.

[0046] Those skilled in the art should understand that this utility model is not limited to the above embodiments.
