[0054] Taking computers, mobile phones, hard drives, network cards, monitors, chargers and other electronic products as examples, due to the large number of components, the manufacturing and assembly process is complex, and after the electronic products are produced, there may be many potential problems, and during use, the electronic products may be used in a high temperature environment. Therefore, before the electronic products are put into use, aging test needs to be carried out to screen out defective products to ensure that the products meet the reliability requirements.

[0055] In the traditional way, the electronic products are usually placed in an aging room for testing. The aging room, also known as a burn-in room, is a device that simulates a high-temperature, harsh environment test for high-performance electronic products. By controlling the environmental temperature in the aging room, the situation of the electronic products working continuously for a long time in a relatively harsh high-temperature environment is simulated to verify the reliability of the electronic products in the harsh high-temperature environment. Among them, through aging test, defective products with poor performance and reliability that do not meet the requirements can be screened out.

[0056] However, the traditional aging room occupies a large space, which occupies the limited land resources of the factory. Moreover, since the space of the aging room is large, it is relatively difficult to keep the environmental temperature stable, and there is a time delay in adjusting the environmental temperature, which is low in efficiency. Among them, the environmental temperature of such a large space as the aging room is generally adjusted and controlled by a central air conditioner, which is high in energy consumption and is not conducive to energy saving and emission reduction.

[0057] In addition, after the aging room is established, it becomes a fixed place and cannot be moved, which does not have the adjustability of production. Moreover, the environmental temperature in the aging room is consistent everywhere, which cannot adapt to the needs of different products requiring different aging temperatures, and the flexibility is poor.

[0058] To address this issue, this embodiment provides an automatic temperature-controlled aging device. This device features an aging chamber within a temperature-controlled enclosure, and an air duct within that chamber. Electronic products are placed within the installation area of ​​the air duct, and the aging temperature is provided by the heat generated by the electronic products themselves during operation. The device automatically adjusts the ambient temperature within the aging chamber to ensure a stable and controllable aging environment for the electronic products. This automatic temperature-controlled aging device offers automatic temperature control, is small in size, highly flexible, practical, and energy-efficient.

[0059] Figure 1 This is an external structural diagram of the automatic temperature-controlled aging device provided in an embodiment of the present invention; Figure 2 This is an internal structural diagram of the automatic temperature-controlled aging device provided in an embodiment of the present invention; Figure 3 for Figure 2 The diagram shows the structure of an assembled electronic product. Figure 4 for Figure 1 A longitudinal sectional view; Figure 5 for Figure 3 Top view after the cover plate has been removed; Figure 6 for Figure 1 The front view.

[0060] Reference Figure 1 and Figure 2 As shown, the automatic temperature-controlled aging device 1 (hereinafter referred to as the aging device) provided in this embodiment includes a temperature control chamber 100, which includes a chamber body 110 and a cover plate 120. The top of the chamber body 110 is open. For example, the chamber body 110 can be an integrally formed structure, which includes a bottom wall and side walls surrounding the bottom wall. One end of the side wall is connected to the bottom wall, and the end of the side wall away from the bottom wall forms the top opening of the chamber body 110. The cover plate 120 covers the top opening of the chamber body 110 to close the space inside the chamber body 110.

[0061] In one specific implementation, the cover plate 120 can be hinged to the top of the box 110. For example, one side of the cover plate 120 is connected to the top of the corresponding side plate of the box 110 via a hinge. When the cover plate 120 is flipped, the hinge between the cover plate 120 and the box 110 rotates and changes angle to open or close the temperature control box 100.

[0062] Alternatively, the cover plate 120 can also be connected to the top of the housing 110 by means of snap-fit, locking, or other methods.

[0063] Reference Figure 3 As shown, after opening the cover 120, the electronic product 2 to be tested can be placed inside the chamber 110. Then, the cover 120 is closed again, so that the electronic product 2 is in a relatively sealed environment, and the ambient temperature inside the temperature control chamber 100 is maintained to meet the aging test requirements of the electronic product 2.

[0064] Specifically, in combination with Figure 2 and Figure 4 As shown in the figure, the temperature control box 100 is provided with an aging chamber 130 and an electric control chamber 140, and the aging chamber 130 and the electric control chamber 140 are separated by a partition plate 113. The electronic product 2 is installed in the aging chamber 130, and the environmental temperature in the aging chamber 130 is controlled to test the aging performance of the electronic product 2. The control panel 500 is installed in the electric control chamber 140, and the environmental temperature in the aging chamber 130 is controlled and adjusted by the control panel 500 to meet the aging temperature requirements of the electronic product 2.

[0065] Among them, the aging temperature of the electronic product 2 refers to the environmental temperature that meets the reliability requirements of the electronic product 2. For example, for an electronic product 2 that needs to work reliably and stably at an environmental temperature of 40℃, its aging temperature is 40℃, at this time, the environmental temperature in the aging chamber 130 should be adjusted to 40℃, and the electronic product 2 is installed in the aging chamber 130 to work continuously and stably for 48h, which indicates that the electronic product 2 can work reliably and stably at the aging temperature of 40℃.

[0066] In addition, the electronic product 2 can be connected to the control panel 500 through the electric connection line, or the electronic product 2 can be plugged on the control panel 500 to realize the electrical connection between the electronic product 2 and the control panel 500, and the working of the electronic product 2 is controlled by the control panel 500.

[0067] In the process of aging test of the electronic product 2, because the environmental temperature in the aging chamber 130 is high, and the control panel 500 has high requirements for the environmental temperature, it will also generate heat during work. If the environmental temperature is too high, it is not conducive to the heat dissipation of the components on the control panel 500, which will affect the stability and reliability of the control panel 500, and even damage the control panel 500, causing it to work.

[0068] To this end, the embodiment separates the aging chamber 130 and the electric control chamber 140 in the temperature control box 100, and isolates the control panel 500 in the electric control chamber 140. The environmental temperature in the electric control chamber 140 is not affected by the aging chamber 130, and the control panel 500 is in a normal temperature environment in the electric control chamber 140, which can ensure the normal and stable work of the control panel 500.

[0069] And, in order to dissipate the heat generated by the control panel 500 in time, the box wall of the box body 110 is also provided with a heat dissipation port 114, and the heat dissipation port 114 is located in the area where the electric control chamber 140 is located. The electric control chamber 140 communicates with the external environment through the heat dissipation port 114, and the heat generated by the control panel 500 is taken away through the convection with the external air, so as to ensure the reliability of the control panel 500.

[0070] In order to rationalize the layout of the temperature control box 100, refer toFigure 4 As shown, in the embodiment, the aging chamber 130 and the electric control chamber 140 can be separated along the height direction of the temperature control box 100. The partition plate 113 is connected to the inner side wall of the box body 110 and is located between the cover plate 120 and the bottom wall of the box body 110 to separate the box body 110 into the aging chamber 130 and the electric control chamber 140 arranged in the upper and lower positions along the height direction. In this way, the electric control chamber 140 does not occupy additional planar space, the overall planar size of the temperature control box 100 is small, the temperature control box 100 occupies a small space and has high flexibility.

[0071] As shown, in the embodiment, the aging chamber 130 and the electric control chamber 140 can be separated along the height direction of the temperature control box 100. The partition plate 113 is connected to the inner side wall of the box body 110 and is located between the cover plate 120 and the bottom wall of the box body 110 to separate the box body 110 into the aging chamber 130 and the electric control chamber 140 arranged in the upper and lower positions along the height direction. In this way, the electric control chamber 140 does not occupy additional planar space, the overall planar size of the temperature control box 100 is small, the temperature control box 100 occupies a small space and has high flexibility.

[0072] For the case that the size of the control board 500 is small, for example, in some other embodiments, the control board 500 can be arranged in a narrow strip shape. At this time, the electric control chamber 140 can be arranged horizontally and parallel to the aging chamber 130. In this way, the overall height of the temperature control box 100 is small, and the narrow electric control chamber 140 can be matched with the narrow strip-shaped control board 500, and the electric control chamber 140 has little effect on the horizontal size of the temperature control box 100.

[0073] In addition, referring to Figure 5 As shown, the aging device 1 of the embodiment is also provided with a power supply 600, for example, a rechargeable secondary battery. The control board 500 in the electric control chamber 140 is electrically connected to the power supply 600. When the temperature control box 100 is electrically connected to an external power supply, the current of the external power supply is transmitted to the control board 500 through the power supply 600. When the power supply 600 itself has sufficient power, the temperature control box 100 can also not be connected to an external power supply, and the power supply 600 discharges to provide current for the control board 500.

[0074] The power supply 600 also generates heat during the charging and discharging process. To ensure the stability of the power supply 600, the power supply 600 should be isolated from the aging chamber 130. For example, the power supply 600 can be arranged together with the control panel 500 in the electric control chamber 140, so that the control panel 500 and the power supply 600 are electrically connected. Alternatively, for the characteristics of the control panel 500 being thin and the power supply 600 being block-shaped, a separate power distribution chamber 150 can be arranged for the power supply 600, and the power supply 600 is installed in the power distribution chamber 150.

[0075] In combination with Figure 4 and Figure 5 As a specific embodiment, the temperature control box 100 is divided into an aging chamber 130, an electric control chamber 140, and a power distribution chamber 150. Along the height direction of the temperature control box 100, the aging chamber 130 and the electric control chamber 140 are arranged vertically. Along the width direction of the temperature control box 100, the power distribution chamber 150 is arranged laterally between the aging chamber 130 and the electric control chamber 140.

[0076] Specifically, a vertical partition plate can be arranged vertically on the bottom wall of the box body 110, the vertical partition plate extends along the length direction of the box body 110 to both ends of the box body 110, and the box body 110 is divided into a power distribution chamber 150 on one side and a space on the other side along the width direction. In the space on the other side, a horizontal partition plate is arranged between the cover plate 120 and the bottom wall of the box body 110, the edge of the horizontal partition plate is connected with the vertical partition plate and the inner side wall of the box body 110, and the space on the other side is divided into an aging chamber 130 on the upper part and an electric control chamber 140 on the lower part.

[0077] In combination with Figure 1 and Figure 5 For the stable working condition of the power supply 600, the power distribution chamber 150 can be arranged as a closed chamber, and heat dissipation holes (not shown in the figure) can be arranged on the side wall or the bottom wall of the box body 110 corresponding to the position of the power distribution chamber 150 to meet the heat dissipation needs of the power supply 600. The top of the box body 110 corresponding to the area of the aging chamber 130 is open, and the cover plate 120 is arranged on the opening of the aging chamber 130.

[0078] The aging device 1 of the present embodiment can be used for aging test by installing electronic products 2 in the aging chamber 130 of the temperature control box 100. The temperature control box 100 has a small volume and is easy to move, and can be placed near the electronic products 2 to be aged. Different products can be placed in different temperature control boxes 100 for aging test according to different aging temperature requirements.

[0079] The structure and layout of the aging chamber 130 will be described in detail below.

[0080] Referring to Figure 1 and Figure 2 As shown in the drawings, the air inlet part 101 and the air outlet part 102 are arranged on the wall of the temperature control box 100, and both of them are communicated with the aging cavity 130. The air duct 131 is arranged in the aging cavity 130, and the mounting area 131a is arranged in the air duct 131. The electronic product 2 is mounted in the air duct 131, and the two ends of the air duct 131 in the extension direction are the air inlet end and the air outlet end respectively. The outside air enters the aging cavity 130 from the air inlet part 101, and the air in the aging cavity 130 enters the air duct 131 from the air inlet end. After the airflow blows through the electronic product 2 in the air duct 131, it flows out from the air outlet end of the air duct 131, and then can flow out to the outside of the temperature control box 100 through the air outlet part 102.

[0081] In actual application, according to the actual size of the electronic product 2, only one electronic product 2 can be placed in the mounting area 131a of the air duct 131; or, as shown in Figure 3 , multiple electronic products 2 can be placed side by side in the air duct 131. In this way, multiple electronic products 2 can be subjected to aging test to improve the test efficiency. When multiple electronic products 2 are placed, the electronic products 2 should be arranged along the width direction of the air duct 131 to ensure that the airflow in the air duct 131 can flow through each electronic product 2 at the same time, so as to avoid that the electronic products 2 hinder the flow of the airflow.

[0082] As shown in Figure 3 and Figure 5 , the air inlet fan 200, the air outlet fan 300 and the temperature sensor 400 are further arranged in the aging cavity 130, and the air outlet fan 300 and the temperature sensor 400 are electrically connected with the control panel 500 in the control cavity 140. The air inlet fan 200 is arranged at the air inlet end of the air duct 131, and the air outlet fan 300 is arranged close to the air outlet end of the air duct 131. The temperature sensor 400 is arranged in the air duct 131, and is used to detect the temperature in the air duct 131. In this way, the ambient temperature of the electronic product 2 can be accurately determined.

[0083] During the working process of the electronic product 2, heat is generated by itself. The heat generated by the electronic product 2 exchanges with the air in the surrounding environment, so that the air around the electronic product 2 is heated, and thus the electronic product 2 is in a high-temperature environment. If the heat continuously accumulates in the aging cavity 130, the electronic product 2 will be in an excessively high ambient temperature, which will cause damage to the electronic product 2. Therefore, by arranging the air inlet part 101 and the air outlet part 102 on the wall of the temperature control box 100, the aging cavity 130 is communicated with the external environment, so that the heat in the aging cavity 130 can be discharged, and the temperature in the aging cavity 130 can be maintained within a safe range.

[0084] At the same time, the electronic product 2 needs to be subjected to aging test in the aging chamber 130, and thus, the aging chamber 130 needs to be maintained at a high aging environment temperature. In the embodiment, the heat generated by the electronic product 2 is used to provide the aging temperature environment, the air in the aging chamber 130 is caused to flow against the outside air by the air inlet fan 200 and the air outlet fan 300, the temperature in the aging chamber 130 is maintained at a suitable aging temperature, and no additional heat generating device needs to be arranged in the aging chamber 130 to provide the aging temperature environment, thereby saving energy.

[0085] The air inlet part 101 arranged on the wall of the temperature control box 100 can be an air inlet hole 101a, which is in communication with the aging chamber 130. As shown in Figure 1 and Figure 2 illustrated, a plurality of air inlet holes 101a can be arranged on the side wall of the box body 110 in a concentrated and spaced manner, and a plurality of air inlet holes 101a can also be arranged on the region of the cover plate 120 close to the air inlet end of the air duct 131 in a concentrated and spaced manner. In actual application, the air inlet holes 101a can be arranged only on the side wall of the box body 110 or the cover plate 120, or can be arranged on both the side wall of the box body 110 and the cover plate 120, and the embodiment does not make a specific limitation in this regard.

[0086] As to the air outlet part 102 arranged on the wall of the temperature control box 100, similar to the air inlet part 101, the air outlet part 102 can include a plurality of air outlet holes 102a arranged in a concentrated and spaced manner. Since the air flowing out of the air outlet end of the air duct 131 flows through the electronic product 2, the flowing-out air is hot air with a relatively high temperature, and in order to smoothly discharge the hot air, the air outlet holes 102a can be arranged in a concentrated manner on the cover plate 120 close to the air outlet end of the air duct 131.

[0087] In addition, the air outlet part 102 can also include an air outlet 102b arranged on the wall of the temperature control box 100, which corresponds to the air outlet surface of the air outlet fan 300, and the air flowing to the air outlet fan 300 can be discharged from the air outlet 102b.

[0088] As shown in Figure 5 In the embodiment, gaps are formed between the two ends of the air duct 131 and the inner side walls of the corresponding two sides of the temperature control box 100, i.e., a gap is formed between the air inlet end of the air duct 131 and the inner side wall of the corresponding side of the temperature control box 100, and a gap is also formed between the air outlet end of the air duct 131 and the inner side wall of the corresponding side of the temperature control box 100, a main air area is formed in the air duct 131, and a mixed air area is formed between the air duct 131 and the inner wall of the temperature control box 100. The air flowing out of the air outlet end of the air duct 131 can enter the mixed air area and mix with the air entering the aging chamber 130 from the outside, and the mixed air again enters the air duct 131 from the air inlet end of the air duct 131, thereby circulating.

[0089] in, Figure 5 The arrows in the diagram indicate the direction of airflow within the aging chamber 130. (Refer to...) Figure 5 As shown, the airflow entering the air duct 131 from the air inlet end of the air duct 131 is heated into hot air after passing through the electronic product 2. The hot air flows out from the air outlet end of the air duct 131. Part of the hot air can flow out to the outside environment from the air outlet 102 of the temperature control box 100, and the other part of the hot air flows to the mixing air zone and mixes with the airflow entering from the air inlet 101 of the temperature control box 100. The mixed airflow enters the air duct 131 from the air inlet end of the air duct 131, flows through the electronic product 2 along the air duct 131, and then flows out from the air outlet end of the air duct 131, thus circulating.

[0090] During this process, the ambient temperature inside the air duct 131 can be detected in real time by the temperature sensor 400, and the detected temperature value is fed back to the control board 500. The control board 500 adjusts and controls the speed of the exhaust fan 300 according to the detected temperature value so that the temperature inside the air duct 131 is maintained within a suitable aging temperature range.

[0091] Taking the aging temperature requirement range of 40℃-45℃ for electronic product 2 as an example, during the aging test, the temperature sensor 400 detects the temperature inside the air duct 131 in real time and feeds back the detected temperature value to the control board 500. If the detected temperature value is higher than 45℃, the control board 500 controls the speed of the exhaust fan 300 to increase the amount of hot air discharged. Since the air pressure inside the aging chamber 130 is balanced with the external air pressure, more cold air enters the mixing air zone from the air inlet 101 of the temperature control box 100, mixes with the remaining hot air, and then enters the air duct 131, thus lowering the temperature inside the air duct 131. If the detected temperature value is lower than 40℃, the control board 500 controls the speed of the exhaust fan 300 to decrease, reducing the amount of hot air discharged. More hot air enters the air duct 131 from the mixing air zone, thus raising the temperature inside the air duct 131.

[0092] In some embodiments, the control board 500 can adjust not only the speed of the exhaust fan 300 but also the speed of the intake fan 200. In this case, the intake fan 200 can also be electrically connected to the control board 500. For example, when the temperature sensor 400 detects that the temperature inside the air duct 131 is higher than the aging temperature range of the electronic product 2, the control board 500 controls both the exhaust fan 300 and the intake fan 200 to increase their speed, thereby increasing the airflow into the aging chamber 130. Conversely, when the temperature sensor 400 detects that the temperature inside the air duct 131 is lower than the aging temperature range of the electronic product 2, the control board 500 controls both the exhaust fan 300 and the intake fan 200 to decrease their speed, thereby reducing the airflow into the aging chamber 130. This allows for rapid adjustment of the temperature inside the aging chamber 130, improving the temperature control efficiency of the aging device 1.

[0093] In the embodiment, the heat generated by the electronic product 2 itself provides the high-temperature environment in the air duct 131, and no additional heat generating device is needed to meet the aging temperature environment in the air duct 131. Moreover, the temperature sensor 400 detects the temperature value in the air duct 131 in real time, and the control board 500 controls the rotating speed of the exhaust fan 300 according to the detected temperature value, so that the air duct 131 can be maintained in a stable aging temperature environment.

[0094] Therefore, the aging device 1 of the embodiment has small volume and high flexibility, can save energy consumption, and can accurately control and adjust the aging temperature and keep the aging temperature stable.

[0095] In the embodiment, as shown in Figure 6 , the outer side wall of the temperature control box 100 facing the operator during testing is designed as an operation panel of the temperature control box 100, and the operation panel is provided with a power key 115 and a temperature display 116. The operator can start or stop the aging device 1 by pressing the power key 115. The temperature display 116 is used to display the temperature detected by the temperature sensor 400 in the aging chamber 130 in real time, so as to facilitate the operator to monitor the temperature in the aging chamber 130 in real time. In addition, the operation panel of the temperature control box 100 can also be provided with an indicator light 117, which is used to indicate the working state of the aging device 1.

[0096] In actual application, when the aging test of the electronic product 2 is performed, the electronic product 2 is placed in the aging chamber 130 of the temperature control box 100, and then the power key 115 is pressed to start the aging device 1. At this time, the intake fan 200 and the exhaust fan 300 can not work, and the heat generated by the electronic product 2 mainly accumulates in the aging chamber 130, so as to rapidly increase the temperature in the aging chamber 130. This process can be called a preheating process. When the temperature in the aging chamber 130 reaches a preset temperature, for example, the aging temperature of the electronic product 2, the control board 500 controls the intake fan 200 and the exhaust fan 300 to start, and controls the rotating speed of the exhaust fan 300 and / or the intake fan 200 according to the real-time temperature detected by the temperature sensor 400, so as to stabilize the temperature in the air duct 131 at the aging temperature.

[0097] For the setting of the air duct 131 in the aging chamber 130, refer to Figure 2 or Figure 3As shown, in the length direction of the temperature control box 100, the two ends of the aging cavity 130 extend to the two ends of the temperature control box 100, in order to reasonably utilize the space in the aging cavity 130, in the embodiment, the air duct 131 can extend along the length direction of the aging cavity 130, that is, the air duct 131 extends along the length direction of the temperature control box 100, the air inlet end and the air outlet end of the air duct 131 are respectively close to the two sides of the temperature control box 100 in the length direction, and there is a gap between the air inlet end and the air outlet end and the inner side wall of the two sides of the temperature control box 100, so as to form air circulation in the aging cavity 130.

[0098] The exhaust fan 300 is close to the inner side wall of the side of the air outlet end of the air duct 131 of the box body 110, so that the exhaust fan 300 is close to the air outlet end of the air duct 131, and the exhaust fan 300 is located in the air outlet area of the air outlet end of the air duct 131, and the air flow discharged from the air outlet end of the air duct 131 can flow smoothly to the exhaust fan 300.

[0099] In order to facilitate the exhaust fan 300 to discharge hot air smoothly, the air inlet surface of the exhaust fan 300 can face the inner bottom wall of the aging cavity 130, and the air outlet surface of the exhaust fan 300 faces the cover plate 120, and the exhaust port 102b is opened on the cover plate 120. The hot air discharged from the air outlet end of the air duct 131 is sucked into the exhaust fan 300 and discharged from the exhaust port 102b on the cover plate 120. At this time, the exhaust fan 300 can be installed on the inner side wall of the box body 110, and there is a gap between the air inlet surface of the exhaust fan 300 and the inner bottom wall of the aging cavity 130.

[0100] Alternatively, in the case that the exhaust fan 300 can smoothly suck the hot air discharged from the air outlet end of the air duct 131, the air inlet surface of the exhaust fan 300 can face the air outlet end of the air duct 131, and the air outlet surface of the exhaust fan 300 faces the inner side wall of the box body 110, and the exhaust port 102b is opened on the side wall of the box body 110.

[0101] In addition, referring to Figure 2 or Figure 3 As shown, in the embodiment, the two side walls of the temperature control box 100 in the length direction can be provided with observation windows 111, and the two observation windows 111 correspond to the two ends of the air duct 131 respectively, and the test personnel can observe the situation in the air duct 131 through the observation windows 111, so as to ensure that the electronic product 2 is in a stable working state, so as not to cause damage due to accident. At this time, the exhaust fan 300 can be arranged close to the corner of the temperature control box 100, and the exhaust fan 300 is located on the side of the air duct 131, so as not to block the visible area of the observation window 111.

[0102] In order to form cold and hot air circulation in the aging cavity 130, referring to Figure 2 or Figure 3As shown, along the width direction of the air duct 131, there should be a gap between at least one side of the air duct 131 and the cavity wall of the corresponding side of the aging cavity 130, and a mixed air area is formed between the air duct 131 and the cavity wall of the aging cavity 130. In this way, a backflow channel can be formed between the air outlet end of the air duct 131, the cavity wall of the aging cavity 130, and the air inlet end of the air duct 131. The hot air discharged from the air outlet end of the air duct 131 enters the mixed air area, mixes with the air flow entering the aging cavity 130 from the air inlet hole 101a provided on the cavity wall of the temperature control box 100, and then enters the air duct 131 from the air inlet end of the air duct 131.

[0103] To ensure air pressure balance on both sides of the air duct 131, taking the case where the air duct 131 extends along the length direction of the aging cavity 130 as an example, as an embodiment, the air duct 131 can be arranged at the middle of the aging cavity 130 in the width direction of the aging cavity 130, and there is a gap between the width direction of the air duct 131 and the cavity wall of the corresponding side of the aging cavity 130. Referring to Figure 5 As shown, the air flow discharged from the air outlet end of the air duct 131 flows along the extension direction of the air duct 131 from both sides of the air duct 131 to the air inlet end of the air duct 131, mixes with the air flow entering from the air inlet part 101 of the temperature control box 100, and then flows to the air inlet end of the air duct 131 and enters the air duct 131.

[0104] Referring to Figure 2 Or Figure 3 As shown, the air duct 131 includes a left air guide plate 1311 and a right air guide plate 1312, and the left air guide plate 1311 and the right air guide plate 1312 are both vertically arranged on the bottom wall of the aging cavity 130. The left air guide plate 1311 and the right air guide plate 1312 both extend along the extension direction of the air duct 131, and the left air guide plate 1311 and the right air guide plate 1312 are oppositely arranged. Taking the case where the air duct 131 extends along the length direction of the aging cavity 130 as an example, the left air guide plate 1311 and the right air guide plate 1312 can both extend along the length direction of the aging cavity 130 and oppositely arranged, and a main air area is formed between the left air guide plate 1311 and the right air guide plate 1312, and the electronic product 2 is installed in the area between the left air guide plate 1311 and the right air guide plate 1312.

[0105] For the case where the mixed air area is formed on both sides of the air duct 131, taking the case where the air duct 131 extends along the length direction of the aging cavity 130 as an example, the air duct 131 is located in the middle region of the width direction of the aging cavity 130, and there is a gap between the left air guide plate 1311 and the cavity wall of the corresponding side of the aging cavity 130, and there is a gap between the right air guide plate 1312 and the cavity wall of the corresponding side of the aging cavity 130.

[0106] If the air duct 131 is at a high height, and the air intake fan 200 is installed on the bottom wall of the air duct 131, the airflow blown out by the air intake fan 200 will mainly be concentrated in the lower part of the air duct 131, which may cause uneven airflow speed and inconsistent air volume in the upper and lower areas of the airflow passing through the electronic product 2.

[0107] In this regard, refer to Figure 2 or Figure 3 As shown, in some embodiments, the air duct 131 may further include an end plate 1313, which is also erected on the bottom wall of the aging chamber 130. The end plate 1313 is located at the air inlet end of the air duct 131, and its two sides are connected to the left air guide plate 1311 and the right air guide plate 1312, respectively. In this case, the air intake fan 200 can be installed on the end plate 1313, and the air intake surface of the air intake fan 200 is fixedly connected to the end plate 1313. In this way, there is no gap between the air intake fan 200 and the air duct 131, which ensures that the airflow accelerated by the air intake fan 200 flows into the air duct 131. Furthermore, the air outlet surface of the air intake fan 200 can face the electronic product 2, so that the airflow in the air duct 131 flows evenly through all parts of the electronic product 2.

[0108] An air inlet (not shown in the figure) is provided on the end plate 1313. An air intake fan 200 is installed at the air inlet, and the air outlet of the air intake fan 200 faces the air inlet. The airflow blown out from the air outlet of the air intake fan 200 enters the air duct 131 through the air inlet.

[0109] In practical applications, if the width of the air duct 131 is large, and a large electronic product 2 can be placed inside the air duct 131, or if multiple electronic products 2 can be placed side by side along the width of the air duct 131, two or more air inlets can be provided at intervals on the end plate 1313 along the width direction of the air duct 131. Each air inlet is equipped with an air intake fan 200 to ensure the uniformity of airflow in each area along the width direction of the air duct 131.

[0110] In addition, for cases where the air duct 131 is relatively high, at least two air intake fans 200 can be installed at intervals along the height direction of the air duct 131 to ensure the uniformity of airflow in each area along the height direction within the air duct 131. This will not be elaborated further.

[0111] Reference Figure 2 As shown, in some other embodiments, the air duct 131 may further include a base plate 1314, which is attached to the bottom wall of the aging chamber 130 and is located between the left guide plate 1311 and the right guide plate 1312. (Refer to...) Figure 3As shown, the electronic product 2 is placed on the bottom plate 1314, and the bottom plate 1314 can be provided with a clamping structure to limit the position of the electronic product 2, so that the electronic product 2 is firmly installed. Alternatively, the bottom plate 1314 can have good thermal conductivity, and the heat generated by the electronic product 2 is conducted to the bottom plate 1314 and dissipated in time through the bottom plate 1314, so as not to damage the electronic product 2 due to overheating.

[0112] In order to improve the uniformity of the airflow in the air duct 131, with reference to Figure 2 or Figure 3 As shown, in this embodiment, in addition to the installation area 131a for placing the electronic product 2, the air duct 131 is also provided with a flow uniformization area 131b, which is located on the air inlet side of the installation area 131a, that is, the flow uniformization area 131b is located between the installation area 131a and the air inlet end of the air duct 131. The flow uniformization area 131b is provided with a flow uniformization net 1315, and a plurality of mesh holes are uniformly and spacedly arranged on the flow uniformization net 1315. The airflow entering the air duct 131 passes through the mesh holes on the flow uniformization net 1315, so that the airflow flowing through each area of the installation area 131a is more uniform, ensuring that the air volume of each part of the electronic product 2 in the installation area 131a is the same, and ensuring the reliability of the aging test.

[0113] Among them, one flow uniformization net 1315 can be installed in the flow uniformization area 131b, or in order to make the airflow flowing through the installation area 131a more uniform, and improve the consistency of the air volume in each area of the installation area 131a, two or more flow uniformization nets 1315 can be spacedly arranged along the extension direction of the air duct 131.

[0114] For example, the two sides of the flow uniformization net 1315 can be fixedly connected with the left and right air deflectors 1311 and 1312 on the two sides by bonding, locking or the like. Alternatively, with reference to Figure 2 or Figure 3 As shown, the fixed part 1316 can be arranged in the flow uniformization area 131b of the air duct 131, and the facing surfaces of the left and right air deflectors 1311 and 1312 are both provided with the fixed part 1316. The fixed part 1316 can be, for example, a rubber part or a silicone part. By arranging a gap in the rubber part or the silicone part, the two sides of the flow uniformization net 1315 are clamped into the gap of the fixed part 1316, so as to fix the flow uniformization net 1315. In this way, the flow uniformization net 1315 is convenient to install and disassemble.

[0115] For the case of fixing the flow-equalizing net 1315 by means of the fixing part 1316 arranged on the inner side of the left and right air deflectors 1311 and 1312, since the fixing part 1316 occupies a certain thickness, in order to prevent it from hindering the air flow into the installation area 131a, the width of the flow-equalizing area 131b of the air duct 131 can be greater than the width of the installation area 131a, that is, the distance between the left and right air deflectors 1311 and 1312 in the flow-equalizing area 131b is large, and the left and right air deflectors 1311 and 1312 form a stepped part a between the flow-equalizing area 131b and the installation area 131a, and the fixing part 1316 is installed in the width area corresponding to the stepped part a.

[0116] In addition, the fixing part 1316 made of a flexible material such as rubber or silicone can be squeezed between the end plate 1313 and the stepped part a, and the fixing part 1316 is compressed and deformed by the force of the end plate 1313 and the stepped part a, so that the fixing part 1316 can firmly fix the flow-equalizing net 1315.

[0117] As for the left and right air deflectors 1311 and 1312 with the stepped part a, the left and right air deflectors 1311 and 1312 can be integrally formed by extrusion molding or injection molding, or the left and right air deflectors 1311 and 1312 can be sequentially connected by a plurality of flat pieces.

[0118] Since the flow-equalizing net 1315 is located in the air duct 131, the flow-equalizing net 1315 is arranged close to the installation area 131a, and the flow-equalizing net 1315 faces the electronic product 2 in the installation area 131a. Therefore, as shown in Figure 5 the temperature sensor 400 can be installed on the flow-equalizing net 1315. For the case of arranging two or more flow-equalizing nets 1315 in the flow-equalizing area 131b, the temperature sensor 400 can be arranged on the flow-equalizing net 1315 close to the installation area 131a, so that the temperature sensor 400 is closer to the electronic product 2 in the installation area 131a, and the accuracy of the detection result of the temperature sensor 400 can be improved.

[0119] In order to more accurately detect the ambient temperature of the electronic product 2, in the present embodiment, two or more temperature sensors 400 can be installed on the flow-equalizing net 1315, and the temperature sensors 400 can be arranged at intervals along the width direction of the air duct 131, for example, three temperature sensors 400 are arranged at intervals along the width direction of the air duct 131 on the flow-equalizing net 1315, and each temperature sensor 400 detects the temperature of a different area in the width direction of the air duct 131, so that the accuracy of temperature detection can be improved, and the temperature in the aging chamber 130 can be more accurately controlled.

[0120] In addition, as mentioned above, the electronic product 2 generates heat during operation, which causes the air around the electronic product 2 to be heated, and the main air area in the air duct 131 becomes a hot air area. The hot air tends to gather at a high position. In the case where the height of the electronic product 2 is lower than the height of the air duct 131, the hot air gathers at the top of the air duct 131, and the temperature of the air flow acting on the electronic product 2 cannot reach the required aging temperature.

[0121] To maintain the uniform temperature in the air duct 131 and the uniform flow rate of the air flow passing through the electronic product 2, the air duct 131 is provided with a plurality of air flow adjusting members 122, as shown in Figs. 1 and 2. Figure 2 or Figure 3 As an embodiment, the side surface of the cover body facing the cabinet 110 is further provided with a flexible air blocking member 121, for example, a foam. The air blocking member 121 extends into the air duct 131 and abuts against the surface of the electronic product 2. The gap between the electronic product 2 and the cover body is covered by the air blocking member 121, which prevents the hot air in the air duct 131 from flowing out from the gap above the electronic product 2 without passing through the electronic product 2, avoids air leakage of the air duct 131, ensures that the hot air in the air duct 131 effectively acts on the electronic product 2, and guarantees that the electronic product 2 is at a suitable aging temperature.

[0122] In addition, to improve the sealing of the aging chamber 130, the top end of the inner side wall of the aging chamber 130 is provided with an air blocking ring 112, which is tightly attached to the cover plate 120. In this way, air leakage of the aging chamber 130 through the gap between the aging chamber 130 and the cover plate 120 is prevented, the temperature in the aging chamber 130 is kept stable, and the stability and reliability of the aging test of the electronic product 2 are ensured.

[0123] It should be understood that the words indicating directions such as upper, lower, upper side, lower side, upper portion, lower portion, top, bottom, top end, bottom end, top end surface, bottom end surface, etc. in the embodiments are based on the positional relationship in the installation and use state of the device or equipment.

[0124] The embodiments or implementations in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other.

[0125] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or equivalently replace some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
