Description

Technical Field

[0001] This utility model belongs to the technical field of high temperature aging test equipment, specifically relating to a high temperature aging chamber. Background Technology

[0002] With the development of science and technology and the increasingly widespread application of new materials, higher requirements are being placed on the durability, stability, and reliability of materials and products. In the field of materials science and engineering, high-temperature aging testing is an important evaluation method used to simulate the long-term performance changes of materials or products under high-temperature environments. A high-temperature aging chamber is one of the key pieces of equipment for conducting such tests; it can simulate various extreme temperature conditions to evaluate the performance of materials or products under these conditions.

[0003] Traditional high-temperature aging chambers, such as Chinese Patent Application No. 202311064906.5 (publication date: May 17, 2024), disclose a hot air internal circulation mechanism for aging equipment and an LCD aging device, belonging to the field of LCD aging equipment technology. It includes a heating chamber, an air supply cabinet, and an aging chamber. The air supply cabinet is installed on top of the heating chamber, and the aging chamber is installed on top of the air supply cabinet. A hot air internal circulation component is provided between the heating chamber, air supply cabinet, and aging chamber to improve the heating efficiency inside the aging chamber and reduce heating energy consumption. The heating chamber in this structure provides the heat source for the entire aging equipment, and the hot air internal circulation component enables the hot air to circulate within the aging chamber. During the heating process, the driven component can rotate the positioned LCD display to improve the heating uniformity of the LCD display. Simultaneously, the hot air in the aging chamber is drawn back into the heating chamber by a circulating fan group for reheating. The hot air, which already has residual heat, reduces the energy consumption required for heating.

[0004] The above literature mainly uses a heating device at the bottom to heat the air and then sends the heated air into the heating chamber through a blower. However, it cannot reduce the temperature of the aging chamber, making it difficult to cool down the chamber. In addition, since it only sends hot air into the chamber from the bottom, it causes uneven heating of the inner and outer sides and the top of the aging chamber. Utility Model Content

[0005] The purpose of this invention is to provide a high-temperature aging chamber that can facilitate cooling of the aging chamber and ensure uniform heating.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-temperature aging chamber includes: a base; a heating seat fixedly connected to the upper end of the base, a vertical rod fixedly connected to the upper end of the heating seat, and two or more evenly distributed brackets fixedly connected to the circumferential surface of the vertical rod; an aging inner shell fixedly connected to the upper end of the heating seat, the aging inner shell being disposed on the outer periphery of the vertical rod; an aging outer shell fixedly connected to the upper end of the base, the aging outer shell being disposed on the outer side of the aging inner shell; a heating circulation mechanism being disposed between the aging inner shell and the aging outer shell; the heating circulation mechanism includes a heating tube and a heat dissipation assembly, the heating tube being fixedly connected to the upper end of the heating seat and covering the outer side of the aging inner shell, the heat dissipation assembly being disposed on the aging outer shell, a protective shell being disposed on the outer side of the aging outer shell, and a heat dissipation vent being disposed on the protective shell, the heat dissipation vent being connected to the heat dissipation assembly.

[0008] The above setup generates heat by placing a heating seat on the base, and then creates a thermal space on the outer periphery of the aging inner shell by placing heating tubes on the outer wall of the aging inner shell. This allows the bottom and top outer periphery of the space inside the aging inner shell to be heated more reliably. When the temperature is relatively high, the fan installed on the aging outer shell is activated to carry the air out of the aging outer shell, thereby accelerating the air circulation and preventing the temperature inside the aging inner shell from becoming too high and damaging the test items.

[0009] Furthermore, the heating cycle mechanism also includes a copper sheet, which is fixedly connected to the outer side of the aging shell, and a heat dissipation component is connected to the copper sheet.

[0010] The above setup uses copper plates to concentrate heat before it is dissipated through the heat dissipation components, thus ensuring reliable heat dissipation.

[0011] Furthermore, the heat dissipation component includes a cooling fan, which is fixedly connected to the side end of the copper sheet, and the aging housing is provided with mounting holes that match the cooling fan.

[0012] The above setup ensures reliable installation by installing a cooling fan on the aged casing.

[0013] Furthermore, a cover plate is connected to the upper end of the aging inner shell and the aging outer shell. The outer side of the cover plate covers the outer side of the aging outer shell and forms a sealed space. A handle is fixedly connected to the upper end of the cover plate.

[0014] The above setup, by creating a sealed space between the cover plate and the aged outer shell, ensures the reliability of the seal.

[0015] Furthermore, a controller is fixedly connected to the upper end of the cover plate, and the bottom of the cover plate is connected to the upright.

[0016] The above settings, by connecting the cover plate to the column, ensure the reliability of the column installation, and by setting up a controller, facilitate convenient control.

[0017] Furthermore, the aging shell has two or more protective shells spaced apart along the outer peripheral wall direction, and a reinforcing plate is provided between two adjacent protective shells, with the reinforcing plate extending along the height direction of the aging shell.

[0018] The above design strengthens the aging shell by adding a protective shell, while also facilitating the formation of heat dissipation holes. Furthermore, the addition of a reinforcing plate further prevents the aging shell from deforming due to thermal expansion and contraction.

[0019] Furthermore, the reinforcing plate has a triangular structure at its top and bottom.

[0020] The above setup, due to the higher temperature at the bottom of the aging shell, makes it more likely to deform, thus requiring a thicker reinforcing plate at the bottom.

[0021] Furthermore, the height of the aged inner shell and the aged outer shell are equal.

[0022] The above settings facilitate matching with the cover. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1

[0033] Please see Figure 1-6 The present invention provides the following technical solution:

[0034] A high-temperature aging chamber includes: a base 1; a heating seat 2 is fixedly connected to the upper end of the base 1.

[0035] A vertical rod 3 is fixedly connected to the upper end of the heating base 2, and multiple evenly distributed hangers 4 are fixedly connected to the circumferential surface of the vertical rod 3.

[0036] The upper end of the heated base 2 is connected to an aging inner shell 6, which includes a honeycomb structure 601.

[0037] An aging shell 7 is fixedly connected to the upper end of the base 1; the aging shell 7 is located on the outside of the aging inner shell 6.

[0038] A heating circulation mechanism is provided between the aging inner shell 6 and the aging outer shell 7. The heating circulation mechanism includes a copper sheet 9, a heating tube 5 and a heat dissipation component. The copper sheet 9 is connected to the outer end of the aging outer shell 7 by bolt thread. The bottom of the heating tube 5 is fixedly connected to the upper end of the heating base 2, and the heating tube 5 covers the outer surface of the aging inner shell 6.

[0039] In a specific embodiment of this utility model, the base 1 serves as the basic support structure for the entire device, supporting all other components. The heating seat 2 is fixedly connected to the upper end of the base 1, serving as the base platform for the heating area. One end of a vertical rod 3 is fixedly connected to the upper end of the heating seat 2, supporting the hanging brackets 4. The vertical rod 3 is fixed to the upper end of the heating seat 2, and multiple evenly distributed hanging brackets 4 are fixedly connected to its circumferential surface. The hanging brackets 4 are used to suspend the sample to be tested, ensuring that the sample is heated evenly during the heating process.

[0040] The aging inner shell 6 is connected to the upper end of the heating base 2 and is set on the outer peripheral wall of the upright 3 to form a heating cavity. The aging inner shell 6 contains a honeycomb structure 601 and is made of a material with good heat transfer effect. This structure can increase the heat exchange area and improve heating efficiency. The aging outer shell 7 is fixedly connected to the upper end of the base 1 and surrounds the aging inner shell 6. The aging outer shell 7 is made of a heat-insulating material to play a role in heat preservation and heat insulation, reducing heat loss.

[0041] like Figure 4 As shown, the heating circulation mechanism includes a copper plate 9, a heating tube 5, and a heat dissipation assembly. The heat dissipation assembly includes a cooling fan 8 and a heat dissipation port 12. The copper plate 9 is bolted to the side of the aging outer shell 7. The heating tube 5 is fixedly connected to the upper end of the heating base 2 and covers the outer wall of the aging inner shell 6. The heating tube 5 is responsible for generating heat, while the heat dissipation assembly is used to regulate the temperature and prevent overheating. The cooling fan 8 is fixedly connected to the side of the copper plate 9 and is responsible for removing heat from the copper plate 9.

[0042] like Figure 3 As shown, the aging outer shell 7 has mounting holes 10, and a cooling fan 8 is installed in the mounting holes 10. A protective shell 11 is connected to the outer side of the aging outer shell 7 to protect the cooling fan 8 and prevent foreign objects from entering. A heat dissipation vent 12 is provided on the protective shell 11, and the heat dissipation vent 12 is connected to the cooling fan 8 to facilitate air circulation and help dissipate heat. A cover plate 14 is connected to the upper end of the aging inner shell 6 and the aging outer shell 7 to seal the heating cavity.

[0043] like Figure 3 As shown, a handle 15 is fixedly connected to the upper end of the cover plate 14 for easy opening and closing. A controller 16 is fixedly connected to the upper end of the cover plate 14, and the bottom of the cover plate 14 is connected to the upright 3. The controller 16 is used to control the working state of the heating tube 5 to achieve temperature control. The bottom of the cover plate 14 is provided with a downwardly extending covering edge 141, which covers the outer wall of the aging shell 7.

[0044] like Figure 1As shown, two or more protective shells 11 are spaced apart along the circumferential direction on the outer wall of the aging shell 7. A reinforcing plate 13 is provided between two protective shells 11. The reinforcing plate 13 protrudes outward on the outer surface of the aging shell 7. The cross-section of the reinforcing plate 13 is triangular to enhance the structural strength of the shell. In this embodiment, the protective shells 11 and the reinforcing plate 13 are made of heat-insulating material. When the sample needs to be subjected to high-temperature aging treatment, the sample is first suspended on the hanger 4, and then the cover plate 14 is closed. The heating tube 5 is started to begin the heating process. At the same time, the cooling fan 8 works to maintain a suitable temperature range. The temperature is set and monitored by the controller 16 to ensure that the test conditions meet the requirements. The controller 16 is only used to control the start of the fan and heating tube, set the temperature, and detect the temperature. The control principle of the controller 16 is existing technology and will not be described in detail here.

[0045] In this embodiment: the cooling fan 8 is fixedly connected to the side of the copper plate 9. The copper plate 9 is connected to the side of the aging chamber 7 by bolt threads. This design ensures that the cooling fan 8 can directly contact the copper plate 9, thereby quickly removing the heat from the copper plate 9. The protective shell 11 is connected to the side of the aging chamber 7 to protect the cooling fan 8 and prevent external foreign objects from entering the cooling system and causing damage. The heat dissipation vent 12 is opened at the side of the protective shell 11 to guide airflow, allowing the hot air exhausted by the cooling fan 8 to be smoothly discharged outside the aging chamber. The protective shell 11 matches the cooling fan 8, ensuring that the cooling fan 8 can effectively dissipate heat through the heat dissipation vent 12, while avoiding airflow short circuits or blockages. When the internal temperature of the aging chamber rises, the cooling fan 8 starts, carrying the heat on the copper plate 9 out of the aging chamber through airflow. The protective shell 11 not only protects the cooling fan 8 from external factors, but also guides airflow through its designed heat dissipation vent 12 to ensure the smooth progress of the heat dissipation process.

[0046] For details, please refer to Figure 1-6 The upper ends of the aging inner shell 6 and the aging outer shell 7 are connected to a cover plate 14, and a handle 15 is fixedly connected to the upper end of the cover plate 14.

[0047] In this embodiment, the cover plate 14 is connected to the upper end of the aging inner shell 6 and the aging outer shell 7. The cover plate design needs to consider both sealing and durability, and is usually made of high-temperature resistant and corrosion-resistant materials, such as stainless steel or special alloys. The size of the cover plate 14 should match the upper end of the aging inner shell 6 and the aging outer shell 7 to ensure a tight fit and prevent external air or moisture from entering the aging chamber and affecting the test results. The handle 15 is fixedly connected to the upper end of the cover plate 14. When it is necessary to open the aging chamber, the operator can easily lift the cover plate 14 by holding the handle 15, thereby exposing the space inside the aging inner shell 6, making it easy to put in or take out the test sample. After the test is completed, the cover plate 14 is closed again by holding the handle 15 to ensure that the inside of the aging chamber is sealed, providing a constant high-temperature environment for the test sample.

[0048] For details, please refer to Figure 1-6 The upper end of the cover plate 14 is fixedly connected to the controller 16, and the bottom of the cover plate 14 is connected to the upright 3.

[0049] In this embodiment: the cover plate 14 is connected to the upper end of the aging inner shell 6 and the aging outer shell 7, and is used to seal the space between the aging inner shell 6 and the aging outer shell 7. The controller 16 is fixedly connected to the upper end of the cover plate 14. The bottom of the cover plate 14 is connected to the upright 3. This design allows the controller 16 to be firmly fixed on the cover plate 14 and facilitates the user to view and adjust parameters during operation. The upright 3 provides additional support for the cover plate 14, ensuring that it will not be displaced or damaged due to improper operation. When aging tests are required, the operator sets the required parameters such as temperature and time through the controller 16.

[0050] For details, please refer to Figure 1-6 The side end of the aging shell 7 is fixedly connected with a reinforcing plate 13, which has a triangular structure at the top and bottom.

[0051] In this embodiment, the reinforcing plate 13 is fixedly connected to the side of the aging shell 7. The reinforcing plate 13 is designed with a triangular structure at both ends, and its upper and lower ends are fixedly connected to the top and bottom of the aging shell 7, respectively. This triangular structure not only enhances the rigidity of the aging shell 7 but also provides some insulation, reducing heat loss through the sides. During the operation of the aging chamber, significant thermal stress is generated due to internal heating; the reinforcing plate 13 effectively disperses this stress, preventing deformation or damage to the aging shell 7.

[0052] For details, please refer to Figure 1-6 The heights of the aged inner shell 6 and the aged outer shell 7 are equal.

[0053] In this embodiment, the heights of the inner shell 6 and the aging outer shell 7 are optimized to be equal. This means that the top surface of the aging inner shell 6 and the top surface of the aging outer shell 7 are on the same horizontal line, forming a unified height standard. This design helps improve the overall coordination of the equipment. The consistent height of the aging inner shell 6 and the aging outer shell 7 ensures that when the cover plate 14 is installed, it can completely cover the upper ends of the aging inner shell 6 and the aging outer shell 7, providing a better sealing effect. At the same time, this design also helps improve the thermal insulation performance of the equipment and reduce heat loss. The equal height of the aging inner shell 6 and the aging outer shell 7 allows the equipment to maintain a consistent height during use, thereby ensuring uniform internal heating and preventing localized overheating or undercooling due to height differences.

[0054] The working principle and usage procedure of this utility model are as follows: First, ensure that the power supply to the aging chamber is connected and check that all electrical connections are secure and reliable. Confirm that there are no foreign objects between the inner aging shell 6 and the outer aging shell 7, and that the heights of the inner aging shell 6 and the outer aging shell 7 are equal. Ensure that the cover plate 14 can close smoothly. Open the cover plate 14 and lift it using the handle 15. Suspend the sample to be tested on the hanger 4 on the upright 3, ensuring sufficient gap between the samples so that the heat can be evenly distributed. Close the cover plate 14, ensuring a complete seal between the cover plate and the inner aging shell 6 and the outer aging shell 7. Set the operating parameters of the aging chamber, including the target temperature, running time, and any other necessary test conditions, through the controller 16. Start the heating program through the controller 16. At this time, heating... Heating tube 5 begins heating, transferring heat to the sample inside the aging chamber 6. Controller 16 monitors the temperature inside the aging chamber 6 in real time and adjusts the temperature via heating tube 5 and cooling fan 8 to ensure the preset test conditions are met. Once the temperature reaches the set value and stabilizes for a period of time, cooling fan 8 starts working, dissipating excess heat through copper plates 9. The protective shell 11 and heat dissipation vents 12 ensure airflow and aid in heat dissipation. After the test, controller 16 is turned off, power is disconnected, and the aging chamber is allowed to cool naturally to a safe temperature. After confirming that the inside of the aging chamber has completely cooled, cover 14 is opened, and the tested sample is carefully removed. Through the usage process provided in this embodiment, users can efficiently complete high-temperature aging tests, ensuring the consistency of test conditions and the reliability of results. Practical application shows that this aging chamber is reasonably designed, easy to operate, and can meet the aging test needs of various materials and components.
