Description

Technical Field

[0001] This utility model relates to the technical field of thermal aging test chambers, specifically to an intelligent thermal aging test chamber. Background Technology

[0002] Intelligent thermal aging test chambers are intelligent devices used to simulate high-temperature environments and test the heat resistance of materials or products. They simulate aging environments through high-temperature and hot air circulation systems to test the performance changes of materials at high temperatures. They are widely used in electronics and electrical appliances: testing the stability of chips, circuit boards, etc. in high-temperature environments; automotive and aerospace: evaluating the heat resistance of engine components and spacecraft electronic equipment; new energy: testing the high-temperature performance of lithium batteries and solar panels; and materials research.

[0003] Traditional intelligent thermal aging test chambers consume a lot of electricity due to long-term high-temperature operation. The temperature of the incoming gas is inconsistent with the temperature inside the chamber, which can easily cause sudden temperature changes and affect the test results. In addition, the temperature is often changed by adjusting the heating tube, which is inefficient. Therefore, we propose an intelligent thermal aging test chamber. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide an intelligent thermal aging test chamber. The chamber uses a temperature controller to adjust the temperature of the heating tube and the preheating tube, which can control the temperature of the incoming air to prevent temperature changes from affecting the test results. Furthermore, it can be adjusted according to the specifications of the parts, thereby increasing the practicality of the device and effectively solving the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intelligent thermal aging test chamber, comprising a chamber body and a temperature control unit;

[0006] Box body: A door is hinged to the front side, and a transparent window is installed on the surface of the door. A placement groove is opened on the front side of the box body. An electric telescopic rod is fixed inside the placement groove. A locking frame that slides with the placement groove is fixed on the top surface of the electric telescopic rod. The locking frame is engaged with the locking groove on the rear side of the door. A heat dissipation hole is opened on the rear side of the box body. An adjustment unit is provided inside the box body.

[0007] Temperature control unit: includes heating element and temperature controller. The heating element is fixed on the left and right sides inside the box, and the temperature controller is fixed on the left side of the box.

[0008] It also includes a touch screen, which is installed on the front side of the housing. The input end of the heating tube is electrically connected to the output end of the temperature controller. The input end of the electric telescopic rod and the temperature controller are electrically connected to the output end of the touch screen. The input end of the touch screen is electrically connected to the output end of an external power supply.

[0009] The temperature controller is activated to control the heating element to regulate the temperature inside the chamber, while the electric telescopic rod is activated to insert the locking bracket into the locking groove to secure the chamber door, preventing accidental opening during testing that could affect the test results and cause safety issues.

[0010] Furthermore, the temperature control unit also includes a motor, a lead screw, an adjusting groove, a baffle plate, a negative pressure fan, and a base. The adjusting groove is located on the rear side of the chamber, and the lead screw is rotatably mounted inside the adjusting groove. The motor is fixed to the rear side of the top surface of the chamber, and the output shaft of the motor is connected to the top of the lead screw. The baffle plate is slidably mounted inside the adjusting groove, and the screw hole in the middle of the baffle plate is threadedly connected to the lead screw. There are two bases, fixed to the bottom of the rear side of the chamber, one on the left and one on the right. A negative pressure fan is placed inside the base. The input ends of the motor and the negative pressure fan are electrically connected to the output end of the control panel. Starting the motor drives the lead screw to rotate, which in turn raises the baffle plate to open the heat dissipation holes. The negative pressure fan can then quickly cool the inside of the chamber to meet different test conditions.

[0011] Furthermore, the temperature control unit also includes a preheating chamber, a preheating tube, a linear motor, and an exhaust duct. The preheating chamber is fixed to the top surface of the chamber. There are two linear motors, one on the left and one on the right, fixed to the rear side inside the chamber. The front side of the linear motor's actuator is connected to the end of the exhaust duct. The air outlet of the preheating chamber is connected to the air inlet of the exhaust duct. The preheating tube is fixed inside the preheating chamber. The input end of the preheating tube is electrically connected to the output end of the temperature controller. The input end of the linear motor is electrically connected to the output end of the touch screen. The preheating tube inside the preheating chamber can preheat the incoming air and activate the linear motor to drive the exhaust duct to rise and fall, so as to make the heat distribution more even and solve the problem of large temperature changes caused by the direct entry of cold air affecting the test.

[0012] Furthermore, the adjustment unit includes a rotating wheel, a screw, a limiting block, a shelf, a rotating table, and a main motor. Limiting blocks are fixed to both sides of the shelf, and these blocks are slidably connected to limiting grooves inside the housing. The rotating wheel is mounted on the top surface of the housing, and a screw is fixed to the bottom end of the rotating wheel. The screw is threadedly connected to a screw hole on the surface of the shelf. A main motor is fixed to the bottom surface of the shelf, and the output shaft of the main motor is connected to the center of the bottom surface of the rotating table. The rotating table is located in a groove on the top surface of the shelf. The input end of the main motor is electrically connected to the output end of the control panel. Rotating the rotating wheel drives the screw to rotate, thus adjusting the height of the shelf. Starting the main motor drives the rotating table to rotate. This allows for the placement or rotation of parts of different specifications according to different test conditions, effectively improving the accuracy of the test and increasing the practicality of the device.

[0013] Furthermore, it also includes a bracket and an infrared thermal imager. The bracket is fixed to the top surface inside the box, and the infrared thermal imager is rotatably connected inside the bracket. The output end of the infrared thermal imager is electrically connected to the input end of the touch screen. The infrared thermal imager can detect the deformation process of the parts in real time, thereby judging the test results.

[0014] Furthermore, it also includes a temperature sensor, which is installed on the front side of the cabinet door. The output of the temperature sensor is electrically connected to the input of the control panel. The temperature sensor can detect the temperature inside the cabinet and automatically adjust the temperature according to the usage.

[0018] 3. The height of the placement plate is adjusted by rotating the screw driven by rotating the wheel. The main motor is started to drive the rotary table to rotate. This allows for the placement or rotation of parts of different specifications according to different test conditions, thereby effectively improving the accuracy of the test and increasing the practicality of the device.
