Description

Technical Field

[0001] This invention relates to the field of memory module testing technology, and in particular to a memory module aging test apparatus and method. Background Technology

[0002] As a core storage component of computers and various electronic devices, the performance and reliability of memory modules directly affect the stability and data security of the entire system. Under the modern trend of high density and high speed design, memory modules generate significant heat during operation. Their core chips are extremely sensitive to temperature. Sustained high temperature or uneven temperature can cause timing errors, performance degradation, and even physical damage. Therefore, aging tests on memory modules before they leave the factory, which involve running them continuously at full load under simulated harsh high-temperature environments, have become a key process for screening out early failure products and ensuring long-term reliability. Currently, commonly used memory module aging test equipment usually consists of a high-temperature test chamber and a built-in test motherboard.

[0003] Existing memory module aging test devices still have some problems during use. For example, the heat dissipation structure of these devices often relies on simple built-in fans and fixed air ducts, resulting in an unreasonable heat dissipation layout and poor temperature uniformity. The existing air duct design and airflow organization methods are insufficient to handle densely packed memory module arrays. Airflow cannot penetrate all test units evenly, easily forming obvious hot and cold spots inside the device. This uneven heat dissipation causes memory modules in different locations to experience varying thermal stresses, affecting the accuracy and consistency of aging screening. Furthermore, under prolonged high-temperature environments, the memory module material itself may release trace amounts of volatile organic compounds and particles. Existing heat dissipation structures only focus on airflow circulation... Cooling causes harmful substances to continuously circulate and accumulate in the closed air duct. These pollutants may recondense when they pass over high-temperature surfaces with the airflow, adhering to memory module contacts or circuits, increasing contact resistance, and even causing corrosion. This results in low thermal management efficiency and does not conform to the trend of intensive heat dissipation design. To maintain the purity of the test environment, the common practice is to directly introduce a large amount of external fresh air and heat it. The corresponding cooling and ventilation system consumes a lot of energy. If the internal air recirculation ratio is increased to save energy, it will exacerbate the above-mentioned problems of uneven temperature field and pollution accumulation. Existing devices lack integrated design for waste heat recovery and air state regeneration at the heat dissipation structure level. They fail to effectively utilize the waste heat discharged during the heat dissipation process for air intake pretreatment, making it difficult to achieve intensive energy utilization while ensuring cooling and ventilation effects. Summary of the Invention

[0004] The purpose of this invention is to provide a memory module aging test device and method. By using a heat dissipation mechanism and a heat recovery mechanism in combination, the invention solves the problems of existing memory module aging test devices, which rely heavily on simple built-in fans and fixed air ducts for heat dissipation, resulting in unreasonable heat dissipation structure layout, poor temperature uniformity, and failure to effectively utilize the waste heat discharged during the heat dissipation process for air intake pretreatment, making it difficult to achieve intensive energy utilization while ensuring cooling and ventilation effects.

[0011] Preferably, a heating wire is fixedly connected inside the heating box, a filter tube is provided on one side of the test box, the filter tube is filled with filter medium, a connecting pipe is connected to one side of the bottom of the recovery box, the other end of the connecting pipe is connected to the heating box, and a recovery pipe is provided inside the recovery box.

[0012] Preferably, the airflow delivery assembly includes a delivery pipe disposed inside the test chamber, a plurality of nozzles opened at the top of the delivery pipe, and an air supply pipe connected to one side of the delivery pipe.

[0013] Preferably, the power adjustment assembly includes a second driving bevel gear fixedly connected to the other side of the electromagnetic clutch, a second driven bevel gear meshing with the second driving bevel gear, a spindle movably connected to the bottom of the recycling bin via a bearing, a reduction gear fixedly connected to the surface of the spindle, a transmission gear meshing with the reduction gear, and a transmission shaft fixedly connected inside the transmission gear.

[0014] A method for using a memory module aging test device includes the following steps:

[0015] S1: The staff first correctly inserts the memory module to be tested into the test board, and then precisely embeds the test board into the limiting groove of the support block on the inner wall of the test chamber through the limiting block at its bottom, completing the installation and positioning. All the connecting wires of the test board are led out through the cable through hole on the side wall of the test box and sealed with elastic sealing rings. Then, they are connected to the computer placed on the external support plate. After the preparation is completed, all the boxes are closed and the test program is started through the computer. The system first checks the status of each sensor and actuator, then the drive mechanism starts, the dual-axis motor runs, and the power of its right output shaft is transmitted through the multi-stage gear reduction in the power adjustment component, which finally drives the rotating box in the dehumidification component to start rotating slowly. At the same time, the fan component starts. The first fan draws the outside air into the dehumidification area of ​​the recovery box after the initial filtration of the dust removal screen. The second fan introduces the dehumidified air into the heating box, heats it through the heating wire, and then delivers it to the delivery pipe. The third fan starts to extract the original air in the test chamber and starts the gas replacement process.

[0016] S2: The computer-controlled electromagnetic clutch engages, enabling the power to be transmitted from the left output shaft of the dual-axis motor. The power is transmitted through the electromagnetic clutch, the second driving bevel gear, and the second driven bevel gear, ultimately driving the reciprocating screw to rotate. Through the helical transmission pair formed by the reciprocating screw and the reciprocating sleeve, the rotational motion is converted into linear motion, driving the extension box, which is fixed to the reciprocating sleeve, to move smoothly up and down in the test chamber along the direction of the first slide rod and the second slide rod. During the up and down reciprocating motion, the driving gear and the toothed plate continuously mesh, forcing the driving gear to rotate. The rotational power is decelerated and reversed once through the worm and worm wheel pair, and then reversed a second time through the first driving bevel gear and the first driven bevel gear, ultimately driving the rotating tube of the disturbance component to rotate around its own axis. The nozzle installed on the rotating tube, under this composite motion trajectory, dynamically and sweepingly sprays hot air from the airflow delivery component to all corners of the test chamber, breaking the static thermal stratification and quickly homogenizing the temperature field between the memory module arrays.

[0017] S3: While the heat is being uniformly heated, the complete heat recovery and air handling cycle operate synchronously. The second fan draws preheated dry air into the heating chamber, where it is precisely heated to the set test temperature by the heating wire. This high-temperature clean air is divided into two paths. The main path enters the U-shaped delivery pipe and is evenly sprayed upwards from the nozzle at the top, establishing a stable high-temperature environment at the bottom of the test chamber. The auxiliary path, through the air supply pipe and a rotary joint, is leak-free delivered to the continuously rotating tube undergoing compound motion, providing an air source for dynamic spraying. After the heating function is completed, the air, carrying trace amounts of volatiles released from the memory module, is drawn out of the test chamber by the third fan. This waste heat air first passes through the filter pipe. The filter media adsorbs and traps volatile organic compounds and particles to complete the purification. The purified hot air enters the recovery pipe in the recovery box and exchanges heat with the cold dry air from the dehumidification area to achieve waste heat recovery. Subsequently, this air is guided to the spray plate of the regeneration component and finally sprayed downward from the nozzle onto the saturated dehumidifying medium in the regeneration station in the rotating box, causing it to desorb and regenerate, restoring its moisture absorption capacity. The high-humidity waste gas generated during regeneration is directly discharged from the workshop through the exhaust pipe, while the dry air that has completed the heat exchange and been preheated enters the heating box through the connecting pipe for final heating, thus forming a closed-loop energy-saving air handling system that integrates heating, utilization, purification, waste heat recovery, and media regeneration.

[0018] S4: Throughout the aging test, a network of temperature and humidity sensors distributed throughout the test chamber, heating chamber, recovery chamber, and key airflow pipelines continuously operates, monitoring environmental parameters at each key node in real time and feeding the data back to the computer control system. The system uses intelligent algorithms to dynamically adjust the speed of the dual-axis motor, the on / off state of the electromagnetic clutch, the airflow of each fan, and the power of the heating wire. The temperature in the core area of ​​the test chamber remains stable at the set target value. The rotary dehumidifier maintains a constant low speed rotation under the drive of the power adjustment component, ensuring that the moisture absorption and regeneration process is continuous and stable. When the preset aging test time ends, the computer controls the heating to stop and stops the drive mechanism and fan components. The staff can then open the chamber door and remove the completed memory module and test board. Through collaborative innovation in dynamic heat equalization, closed-loop air treatment, and intelligent drive distribution, the entire device achieves high uniformity, high cleanliness, and low energy consumption in the high-temperature aging test environment.

[0019] The beneficial effects of this invention are as follows: the heat equalization mechanism and the heat recovery mechanism are driven by a dual-axis motor and an electromagnetic clutch respectively. The reciprocating screw drives the extension box to move up and down reciprocally. Through the meshing transmission of the toothed plate and the drive gear, the rotating tube rotates simultaneously during the movement. The nozzle forms a composite sweeping airflow. Combined with the continuous rotation of the rotating box, dehumidification and regeneration are synchronized, forming a closed-loop air treatment. This achieves dynamic and uniform distribution of hot air in the test chamber, effectively eliminating temperature stratification. At the same time, the energy consumption is significantly reduced through waste heat recovery and medium regeneration, ensuring high uniformity, high cleanliness and low energy consumption operation of the high-temperature aging test environment.

The disturbance assembly 57 includes a rotating tube 571 fixedly connected to the bottom of the first driven bevel gear 565, several nozzles 572 connected to the side wall of the rotating tube 571, and a rotary joint 573 connected to the bottom of the rotating tube 571. The rotating tube 571 is hollow and is movably connected to the bottom of the extension box 55 through bearings, thereby being supported and achieving smooth rotation. Through the setting of the heat equalization mechanism 5, the simulated high-temperature hot air is evenly distributed into the test chamber 2. Inside the test box 1 A heat recovery mechanism 6 is provided, which includes a fan assembly 61 located on one side of the test chamber 1. The fan assembly 61 includes a first fan 611 fixedly connected to the bottom of the recovery box 62, a second fan 612 fixedly connected to the top of the heating box 65, and a third fan 613 fixedly connected to one side of the test chamber 1.

The recovery box 62 is fixedly connected inside the test chamber 1, and a dehumidification assembly 63 is located inside the recovery box 62. The dehumidification assembly 63 includes a rotating box 631 located inside the recovery box 62.A partition plate 632 is fixedly connected inside the rotating box 631. The rotating box 631 contains a dehumidifying medium and has a vent hole at its bottom. A regeneration assembly 64 is installed inside the recycling box 62. The regeneration assembly 64 includes a regeneration box 641 fixedly connected inside the recycling box 62, a regeneration groove 642 inside the regeneration box 641, a spray plate 643 fixedly connected inside the regeneration box 641, and several nozzles 644 communicating with the bottom of the spray plate 643. Half of the rotating box 631 is located in the regeneration groove 642, and the bottom of the nozzles 644 extends into the regeneration groove 642. A heating chamber 65 is connected to one side of the test chamber 1, and an airflow delivery assembly 66 is installed inside the test chamber 2. The airflow delivery assembly 66 includes a delivery pipe 661 installed inside the test chamber 2, several nozzles 662 opened at the top of the delivery pipe 661, and an air supply pipe 663 connected to one side of the delivery pipe 661. The air outlet of the second fan 612 is connected to the delivery pipe 661. The delivery pipe 661 is U-shaped and installed at the bottom of the test chamber 2. The other end of the air supply pipe 663 is connected to the rotary joint 573. Temperature and humidity sensors are installed inside the test chamber 2, the heating chamber 65, and the recovery box 62, as well as in the airflow pipes connecting the various components. The instrument is used to monitor temperature and humidity information. Through the heat recovery mechanism 6, hot air is supplied to the test chamber 2 and recycled. A drive mechanism 7 is installed inside the test chamber 1. The drive mechanism 7 includes a dual-axis motor 71 fixedly connected inside the test chamber 1, an electromagnetic clutch 72 fixedly connected to the output end of the dual-axis motor 71, and a power adjustment assembly 73 located at the output end of the dual-axis motor 71. The power adjustment assembly 73 includes a second driving bevel gear 731 fixedly connected to the other side of the electromagnetic clutch 72, and a second driven bevel gear 732 meshing with the second driving bevel gear 731, which is movably connected to the test chamber 2 via bearings. The recycling bin 62 has a spindle 733 at the bottom, a reduction gear 734 fixedly connected to the surface of the spindle 733, a transmission gear 735 meshing with the reduction gear 734, and a transmission shaft 736 fixedly connected inside the transmission gear 735. There are two second driving bevel gears 731 and two second driven bevel gears 732. A reciprocating screw 521 is fixedly connected to the left second driven bevel gear 732, and the transmission shaft 736 is fixedly connected to the right second driven bevel gear 732. The top of the spindle 733 is fixedly connected to the bottom of the rotating box 631. The drive mechanism 7 provides driving force for the heat equalization mechanism 5 and the heat recovery mechanism 6.

[0037] By setting the moving component 52, the output power of one end of the dual-axis motor 71 can be transmitted to the reciprocating screw 521. Then, using the helical transmission pair between the reciprocating screw 521 and the reciprocating sleeve 522, the rotational motion is converted into continuous up-and-down reciprocating movement of the reciprocating sleeve 522 and the extension box 55 fixed thereto along the direction of the first slide bar 524. During this movement, the toothed plate 53 fixed on the extension box 55 will continuously mesh with the drive gear 54, thereby transferring some kinetic energy to the transmission component 56. Finally, the disturbance component 57 is driven to rotate continuously while moving up and down, thus completing the directional and uniform spraying of hot air into the test chamber 2. Through the setting of the transmission component 56, during the up-and-down reciprocating movement of the extension box 55, the drive gear 54 meshes with the toothed plate 53... Under meshing action, the rotational power is transmitted to the rotating rod 563 via the worm gear 561 and worm wheel 562 pair, realizing the first-stage reduction and transmission direction conversion. Then, through the meshing of the first driving bevel gear 564 and the first driven bevel gear 565, a second direction conversion is performed, and finally the rotational power is reliably transmitted to the disturbance component 57, driving it to rotate continuously. With the setting of the disturbance component 57, while the extension box 55 drives its overall up-and-down reciprocating movement, the rotating tube 571 receives power from the transmission component 56 and continuously rotates around its own axis. The nozzle 572 installed on it performs a compound motion accordingly, thereby continuously and evenly spraying hot air into various areas within the test chamber 2. The rotary joint 573 is the key sealing part for this component to achieve continuous air supply. The rotating ring is fixedly connected to the bottom of the rotating tube 571 and rotates with it. The stationary ring is fixed to the bottom of the extension box 55 by a mounting flange and is connected to the air supply pipe 663 in the air supply assembly 66. The two are dynamically sealed by a high-performance axial mechanical seal to ensure that hot air can be delivered to the rotating nozzle 572 without leakage under the combined motion of continuous rotation and up-and-down reciprocating motion. The first fan 611 is used to introduce and blow external air to the dehumidification assembly 63 for dehumidification. The second fan 612 is used to introduce the dehumidified and preheated external air into the heating box 65 for heating and to deliver the heated air to the air supply assembly 66. The third fan 613 is used to remove the hot air used in the test chamber 2. The hot air is drawn out and transported to the recovery box 62 for waste heat recovery. Finally, the recovered hot air is sent to the dehumidification component 63 for regeneration of the desiccant, thus forming a continuous and energy-saving air handling cycle. Through the dehumidification component 63, the partition plate 632 divides the desiccant into four groups. During use, the rotating box 631 rotates continuously and slowly, allowing dehumidification and regeneration to occur simultaneously. External air first flows through the dry desiccant area for dehumidification, and then this area rotates with the rotating box 631 to the regeneration station for regeneration. Through the regeneration component 64, when the regeneration component 64 is working, the waste hot air from the test chamber 2 drawn out by the third fan 613 is transported through the recovery pipe 20, first exchanging heat with the dehumidified cold air to preheat the latter.The remaining hot air enters the spray plate 643 and is finally sprayed downwards by the nozzle 644 into the dehumidifying medium area located in the regeneration groove 642, achieving dehumidification and regeneration. This process can effectively restore the performance of the dehumidifying medium and extend its service life. Through the airflow conveying component 66, the second fan 612 sends the hot air heated by the heating box 65 into the U-shaped conveying pipe 661, which is sprayed upwards through the evenly distributed nozzles 662 at its top, thereby forming a uniform and stable basic temperature field at the bottom of the test chamber 2, achieving comprehensive and uniform heating of the memory module. Some of the hot air is diverted through the air supply pipe 663 on one side of the conveying pipe 661 and continuously delivered to the rotating pipe 571 through the rotary joint 573, providing a dynamic hot air source for the disturbance component 57, causing it to rotate and spray during its up-and-down reciprocating movement, enhancing the disturbance and mixing of the airflow in the chamber, and improving the local heat dissipation efficiency. Temperature uniformity is ensured by the power adjustment component 73, which allows for flexible switching and distribution of the output power of the dual-axis motor 71 through the on / off switching of the electromagnetic clutch 72. When the electromagnetic clutch 72 is engaged, the power from the left output shaft of the dual-axis motor 71 is transmitted via the electromagnetic clutch 72 to the left second driving bevel gear 731, driving the left second driven bevel gear 732 and its connected reciprocating screw 521 to rotate, thus driving the extension box 55 to reciprocate up and down. Simultaneously, the power from the right output shaft of the dual-axis motor 71 is transmitted sequentially via the right second driving bevel gear 731, the second driven bevel gear 732, the drive shaft 736, the drive gear 735, and the reduction gear 734 to the spindle 733, ultimately driving the rotating box 631 to rotate slowly. This multi-stage gear transmission achieves the required speed reduction and torque increase, ensuring that the rotating box 631 operates continuously at a suitable speed. Example 2

Cable through hole 12 is used for the centralized outflow of data and power connection harnesses of test board 3 to connect to external equipment. Elastic sealing ring 13 can be pressed and sealed after wire threading to effectively prevent leakage of temperature-controlled airflow inside the chamber and maintain the stability of the test environment. The support plate provides a dedicated support platform for the external test computer 4. The dust filter 11 filters the air entering from the outside to prevent external dust from entering.

Through the sliding pair formed by the second slider 14 and the second slide rod 15, a stable linear guide and support is provided on the side of extension box 55 away from the screw drive pair. This effectively restricts the degree of freedom of extension box 55 in reciprocating motion and ensures that it moves smoothly and stably up and down in the vertical direction, thereby enhancing the rigidity and reliability of the entire motion system. Example 3

[0040] Please see Figure 8 , Figures 11-13 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0041] Specifically, a sealing plate 17 is fixedly connected to the top of one side of the regeneration box 641. The sealing plate 17 is located on the top of the rotating box 631 on the other side, and the sealing plate 17 has a ventilation slot. Through the arrangement of the sealing plate 17 and the ventilation slot, the sealing plate 17 and the regeneration box 641 cooperate to divide the recycling box 62 into a relatively independent dehumidification area and a waste heat utilization area. The external air introduced by the first fan 611 is blown upward into the rotating box 631 through one side of the bottom, and dehumidified by the internal dehumidification medium. After being humidified, the air becomes dry and flows upward, eventually entering the waste heat utilization area through the ventilation channel for heat exchange. This effectively avoids mutual interference between the dehumidifying airflow and the regeneration airflow, ensuring independent and efficient operation of each process. A heating wire is fixedly connected inside the heating chamber 65. A filter tube 18 is installed on one side of the test chamber 1, filled with filter media. A connecting pipe 19 is connected to one side of the bottom of the recovery chamber 62, with the other end of the connecting pipe 19 connected to the heating chamber 65. A recovery pipe 20 is installed inside the recovery chamber 62 for filtration. One end of pipe 18 is connected to suction pipe 16, and the other end of filter pipe 18 is connected to recovery pipe 20. The other end of recovery pipe 20 is connected to spray plate 643. The bottom of regeneration box 641 is connected to an exhaust pipe, which is located at the bottom of regeneration groove 642 and extends to the outside of the workshop. Recovery pipe 20 is U-shaped and installed inside recovery box 62. Through the setting of heating wire, the preheated airflow is heated to the temperature required for testing. Filter pipe 18 is used to adsorb and filter trace amounts of volatile organic compounds and particulate matter released by electronic components such as memory modules during high-temperature testing to ensure the cleanliness of the exhaust airflow. Connecting pipe 19 is used to connect recovery box 62 and heating box 65. Recovery pipe 20 is used to exchange heat with the air in recovery box 62 to preheat the air and deliver the used hot air to spray plate 643 for reuse of residual heat. By extending the exhaust pipe, the high humidity air generated during the regeneration of dehumidifying medium is directly discharged to the outside of the workshop to avoid the accumulation of humid and hot gas in the testing area, thereby maintaining the stability of the environment around test box 1.

[0042] The working principle of this invention is as follows: First, the operator correctly inserts the memory module to be tested into the test board 3, and then precisely embeds the test board 3 into the limiting groove 10 of the support block 8 on the inner wall of the test cavity 2 via the limiting block 9 at its bottom, completing the installation and positioning. All connecting wires of the test board 3 are led out through the cable through-hole 12 on the side wall of the test box 1 and sealed by the elastic sealing ring 13. Then, it is connected to the computer 4 placed on the external support plate. After preparation, all boxes are closed, and the test program is started through the computer 4. The system first self-checks the status of each sensor and actuator, and then drives the mechanism. 7. When started, the dual-shaft motor 71 operates, and the power of its right output shaft is transmitted through the multi-stage gear reduction in the power adjustment component 73, ultimately driving the rotating box 631 in the dehumidification component 63 to start rotating slowly. At the same time, the fan component 61 starts. The first fan 611 draws the outside air into the dehumidification area of ​​the recovery box 62 after preliminary filtration by the dust removal screen 11. The second fan 612 introduces the dehumidified air into the heating box 65, heats it through the heating wire, and then delivers it to the delivery pipe 661. The third fan 613 starts to extract the original air in the test chamber 2, starting the gas replacement process.

[0043] Computer 4 controls the engagement of electromagnetic clutch 72, enabling power transmission from the left output shaft of dual-shaft motor 71. Power is transmitted through electromagnetic clutch 72, second driving bevel gear 731, and second driven bevel gear 732, ultimately driving reciprocating screw 521 to rotate. Through the helical transmission pair formed by reciprocating screw 521 and reciprocating sleeve 522, the rotational motion is converted into linear motion, driving the extension box 55, which is fixed to reciprocating sleeve 522, to move smoothly up and down within test chamber 2 along the directions of first slide rod 524 and second slide rod 15. During this up-and-down reciprocating movement, the drive gear 54 and gear plate... 53 continues to mesh, forcing the drive gear 54 to rotate. The rotational power is decelerated and reversed once through the worm gear 561 and worm wheel 562 pair, and then reversed again through the first driving bevel gear 564 and the first driven bevel gear 565. Finally, it drives the rotating tube 571 of the disturbance component 57 to rotate around its own axis. Under this composite motion trajectory, the nozzle 572 installed on the rotating tube 571 sprays hot air from the airflow delivery component 66 into various corners of the test chamber 2 in a dynamic and sweeping manner, breaking the static thermal stratification and quickly homogenizing the temperature field between the memory module arrays.

[0044] While the heat is being uniformly heated, the complete heat recovery and air handling cycle operate synchronously. The second fan 612 draws preheated dry air into the heating chamber 65, where it is precisely heated to the set test temperature by the heating wire. This high-temperature clean air is divided into two paths. The main path enters the U-shaped delivery pipe 661 and is evenly sprayed upwards from the nozzle 662 at its top, establishing a stable high-temperature environment at the bottom of the test chamber 2. The auxiliary path is delivered leak-free through the air supply pipe 663 and the rotary joint 573 to the continuously rotating pipe 571, which is undergoing compound motion, providing an air source for dynamic spraying. After the heating function is completed, the air, carrying trace amounts of volatiles released from the memory module, is drawn out of the test chamber 2 by the third fan 613. This waste heat air first passes through the filter pipe 1. 8. The filter medium adsorbs and traps volatile organic compounds and particles to complete the purification. The purified hot air enters the recovery pipe 20 in the recovery box 62 and exchanges heat with the cold dry air from the dehumidification area to achieve waste heat recovery. Subsequently, this air is guided to the spray plate 643 of the regeneration component 64 and finally sprayed downward from the nozzle 644 onto the saturated dehumidifying medium in the regeneration station in the rotating box 631 to desorb and regenerate it, restoring its moisture absorption capacity. The high-humidity waste gas generated during regeneration is directly discharged from the workshop through the exhaust pipe, while the dry air that has completed the heat exchange and been preheated enters the heating box 65 through the connecting pipe 19 for final heating, thus forming a closed-loop energy-saving air treatment system that integrates heating, utilization, purification, waste heat recovery, and medium regeneration.

[0045] Throughout the aging test, a network of temperature and humidity sensors distributed throughout the test chamber 2, heating chamber 65, recovery chamber 62, and key airflow pipelines continuously monitors environmental parameters at each key node in real time and feeds the data back to the computer 4 control system. The system dynamically adjusts the speed of the dual-axis motor 71, the on / off state of the electromagnetic clutch 72, the airflow of each fan, and the power of the heating wire through intelligent algorithms. The temperature in the core area of ​​the test chamber 2 remains stable at the set target value. The rotary dehumidifier maintains a constant low speed rotation under the drive of the power adjustment component 73, so that the moisture absorption and regeneration process can proceed continuously and stably. When the preset aging test time ends, the computer 4 controls the heating to stop and stops the drive mechanism 7 and the fan component 61. The staff can open the chamber door and take out the memory module and test board 3 that have completed the test. The entire device achieves high uniformity, high cleanliness, and low energy consumption operation of the high-temperature aging test environment through collaborative innovation in dynamic heat equalization, closed-loop air treatment, and intelligent drive distribution.

9. A method of using a memory module aging test device, based on the memory module aging test device according to claim 8, characterized in that, Includes the following steps: S1: The staff first correctly inserts the memory module to be tested into the test board (3), and then precisely embeds the test board (3) into the limiting groove (10) of the support block (8) on the inner wall of the test cavity (2) through the limiting block (9) at its bottom, thus completing the installation and positioning. All the connecting wires of the test board (3) are led out through the cable through hole (12) on the side wall of the test box (1) and sealed by the elastic sealing ring (13). Then, it is connected to the computer (4) placed on the external support plate. After the preparation work is completed, all the boxes are closed, and the test program is started through the computer (4). The system first checks the status of each sensor and actuator, and then the drive mechanism (7) is started. The dual-shaft motor (71) operates, and the power of its right output shaft is transmitted through the multi-stage gear reduction in the power adjustment component (73), which ultimately drives the rotating box (631) in the dehumidification component (63) to start rotating slowly. At the same time, the fan component (61) starts. The first fan (611) draws the outside air into the dehumidification area of ​​the recovery box (62) after the initial filtration of the dust removal net (11). The second fan (612) introduces the dehumidified air into the heating box (65), heats it through the heating wire, and then delivers it to the delivery pipe (661). The third fan (613) starts to extract the original air in the test chamber (2) and starts the gas replacement process. S2: The computer (4) controls the electromagnetic clutch (72) to engage, enabling the power of the output shaft on the left side of the dual-shaft motor (71) to be transmitted. The power is transmitted through the electromagnetic clutch (72), the second driving bevel gear (731), and the second driven bevel gear (732), ultimately driving the reciprocating screw (521) to rotate. Through the helical transmission pair formed by the reciprocating screw (521) and the reciprocating sleeve (522), the rotational motion is converted into linear motion, driving the extension box (55) fixed to the reciprocating sleeve (522) to move smoothly up and down in the test chamber (2) along the direction of the first slide rod (524) and the second slide rod (15). During the up and down reciprocating motion, the driving gear (521) is driven to rotate. 4) The continuous meshing with the toothed plate (53) forces the drive gear (54) to rotate. The rotational power is decelerated and reversed once through the worm gear (561) and worm wheel (562) pair, and then reversed again through the first active bevel gear (564) and the first driven bevel gear (565). Finally, the rotating tube (571) of the disturbance component (57) is driven to rotate around its own axis. The nozzle (572) installed on the rotating tube (571) sprays hot air from the airflow delivery component (66) into each corner of the test chamber (2) in a dynamic and sweeping manner under this composite motion trajectory, breaking the static thermal stratification and quickly homogenizing the temperature field between the memory strip arrays. S3: While the heat is being uniformly heated, the complete heat recovery and air treatment cycle are running synchronously. The second fan (612) draws the preheated dry air into the heating chamber (65), which is precisely heated to the set test temperature by the heating wire. This high-temperature clean air is divided into two paths. The main path enters the delivery pipe (661) and is evenly sprayed upward from the nozzle (662) at the top, establishing a stable basic high-temperature environment at the bottom of the test chamber (2). The auxiliary path is delivered through the air supply pipe (663) and through the rotary joint (573) without leakage to the rotating pipe (571) which is continuously performing compound motion, providing an air source for dynamic spraying. After the heating function is completed, the air, carrying trace amounts of volatiles released from the memory stick, is drawn out of the test chamber (2) under the action of the third fan (613). This waste heat air is first filtered. The filter medium in the tube (18) adsorbs and traps volatile organic compounds and particles to complete the purification. The purified hot air enters the recovery tube (20) in the recovery box (62) and exchanges heat with the cold dry air from the dehumidification area to realize the recovery of waste heat. Then, this air is introduced into the spray plate (643) of the regeneration component (64) and finally sprayed downward from the nozzle (644) onto the saturated dehumidifying medium in the regeneration station in the rotating box (631) to desorb and regenerate it and restore its moisture absorption capacity. The high-humidity waste gas generated by regeneration is directly discharged from the workshop through the external exhaust pipe. The dry air that has completed the heat exchange and been preheated enters the heating box (65) through the connecting pipe (19) for final heating, thereby forming a closed-loop energy-saving air treatment system that integrates heating, utilization, purification, waste heat recovery and medium regeneration. S4: Throughout the aging test, the temperature and humidity sensor network distributed throughout the test chamber (2), heating chamber (65), recycling chamber (62) and key airflow pipelines works continuously to monitor the environmental parameters of each key node in real time and feed the data back to the computer (4) control system. The system dynamically adjusts the speed of the dual-axis motor (71), the on / off state of the electromagnetic clutch (72), the air volume of each fan and the power of the heating wire through intelligent algorithms. The temperature of the core area of ​​the test chamber (2) remains stable at the set target value. The rotating dehumidifier maintains a constant low speed rotation under the drive of the power adjustment component (73), so that the moisture absorption and regeneration process is carried out continuously and stably. When the preset aging test time ends, the computer (4) controls the heating to stop and stops the drive mechanism (7) and the fan component (61). The staff opens the chamber door and takes out the memory stick and test board (3) that have completed the test.
