[0037] Working principle: First, the memory module under test is securely installed in the memory slot cavity 210 below the upper and lower partition plates 207. It is electrically connected to the lower EMR motherboard to ensure electrical signal interaction during testing. When starting the test, the equipment is started via the power switch 106 on the sheet metal back cover 102 of the electrical box. The operation of the high-temperature cover switch 104 is controlled by the logic of the main control board 110, which starts the motor 208. The output shaft of the motor 208 drives the gear 209 to rotate through the connecting rod, which meshes with the rack fixed to the top of the high-temperature cover 213, driving the high-temperature cover 213 to slide smoothly out along the track at the bottom of the fixed plate, completely covering and sealing the memory slot cavity 210 and the heating box 217 below. The core testing space is then established. Subsequently, the aging test program is initiated. The main control board 110, based on a preset temperature curve, activates the PTC heating element 215 located inside the support 212 at the top of the high-temperature enclosure 213 by controlling the relay 109 mounted on the partition plate 107. Simultaneously, the exhaust fan 214 on the support 212 starts, forcibly blowing the heat generated by the PTC downwards, evenly flowing over the surface of the memory modules within the FR4 fiberglass-coated cavity. The hot airflow, blocked at the bottom of the cavity, naturally flows upwards back to the top area, forming a closed-loop hot air circulation. This active forced convection mode, combined with the excellent thermal insulation performance of the FR4 fiberglass-coated board, ensures the heat within the cavity is effectively controlled. The temperature is rapidly and evenly distributed, eliminating uneven heating and cooling. The temperature sensor on the temperature-sensing PCB 108 directly senses the area near the memory module's working area and feeds this real temperature signal back to the main control board 110. The main control board 110 compares this measurement value with the preset target aging temperature and dynamically adjusts the power of the PTC heating element 215 via the relay 109 based on the deviation value, forming a closed-loop precise temperature control system based on the temperature of the memory module itself. The upper and lower layer partition plates 207 and their sealing strips effectively prevent the heat from the upper high-temperature cavity from being transferred to the lower layer. When the temperature-sensing PCB 108 detects that the temperature near the memory module inside the high-temperature cover 213 is higher than the set value, the main control board 110... 0. The heat dissipation program is immediately started, and the motor 208 is controlled to run. Through the gear and rack transmission mechanism 209, the left and right baffles are driven to move outward synchronously and open. After the baffles are opened, the overheated air accumulated in the temperature cavity is quickly flowed to the reserved outer cavity space outside the temperature cavity through the open air outlet under the residual pressure of the internal circulating fan and natural convection. The outer cavity space of the electrical box exhausts the hot air through the heat dissipation port 103, the heat dissipation port 212 and the electrical box cooling fan 113. The lower water cooling fan 204, the lower cooling fan 203 and the heat dissipation hole 202 work together to provide necessary cooling for the server motherboard. The operating status of the equipment can be displayed by the lights on the indicator PCB board 216.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
