Description

Technical Field

[0001] This invention relates to the field of power supply testing technology, specifically a high-frequency power switch aging test device capable of intelligent temperature control. Background Technology

[0002] Power switches need to undergo aging tests before leaving the factory. These tests are mainly used to simulate the long-term working environment of power switches under high temperature and high frequency switching conditions. The built-in intelligent temperature control system precisely adjusts the temperature of the test chamber to accelerate the exposure of potential defects in the device and evaluate its reliability and lifespan. Existing equipment usually adopts a forced airflow circulation design to ensure uniform temperature in the test chamber and supports simultaneous testing at multiple stations to improve aging screening efficiency.

[0003] However, when multiple power supplies are densely placed in the test chamber in existing equipment, the compact layout can easily cause the power supply casings to block each other, severely hindering the directional flow of heat dissipation airflow and forming local eddies or high-temperature dead zones. This not only affects the actual adjustment effect of the temperature control system, but also easily causes uneven temperature at each test position. Some power supplies may fail prematurely due to poor heat dissipation, directly affecting the accuracy and consistency of aging test results. Summary of the Invention

[0004] The purpose of this invention is to provide a high-frequency power switch aging test device with intelligent temperature control, so as to solve the problem in the prior art where the power supply casings block each other, forming local eddies or high-temperature dead zones, causing uneven temperatures at each test position, which affects the accuracy and consistency of aging test results.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A high-frequency power switch aging test device with intelligent temperature control is provided. The aging test device includes a chamber, which contains a temperature control mechanism, a sealing mechanism and a detection mechanism. A control box is provided on one side of the chamber.

[0007] The test chamber is located in the middle of the chamber, the airflow channel is located on the side of the chamber, and the exhaust channel is located on the top of the chamber.

[0008] The temperature control mechanism includes guide vanes, and the guide vanes are equipped with an adjustment unit;

[0009] The test chamber is equipped with a socket and an aging test plate. The airflow channel is equipped with a heating unit, a fan and a distribution unit. The distribution unit distributes the airflow into the test chamber, and the adjustment unit adjusts the angle of the guide vanes to control the temperature in a directional manner according to the results of the testing mechanism.

[0010] By setting multiple partitions inside the chamber, the test chamber is divided into multiple layers. Each partition has multiple sockets and aging test plates, allowing the testing equipment to test multiple high-frequency power switches simultaneously. The power switch input is inserted into the socket, and the power switch output is inserted into the aging test plate to perform aging tests. A temperature control mechanism controls the temperature inside the test chamber. A fan draws air in from the air inlet of the chamber and directs it into the airflow channel. The detection mechanism controls the distribution unit based on the temperature of each test chamber layer to distribute the airflow into each test chamber layer. Based on the temperature distribution of each test chamber layer detected by the detection mechanism, the adjustment unit changes the angle of the guide vanes, causing the airflow from the distribution unit to change direction after hitting the guide vanes, thus directing the airflow in a specific direction for temperature control and achieving intelligent temperature control. After passing through the test chamber, the airflow exits through the exhaust channel at the top of the chamber.

[0011] Furthermore, the adjustment unit includes an adjustment motor, and the output end of the adjustment motor is provided with a rotating rod;

[0012] Converging plates are provided on both sides of the guide vanes;

[0013] The rotating rod is connected to the guide vane, and the guide vane is equipped with a control unit, which controls the rotation of the two convergent plates.

[0014] By installing a rotating rod on the guide vane, with one end rotatably connected to the housing and the other end fixed to the regulating motor, the regulating motor can drive the guide vane to rotate along the axis of the rotating rod, thereby changing the angle of the guide vane. The airflow from the distribution unit changes direction after hitting the guide vane. By changing the angle of the guide vane, it can be directed to different directions, thus achieving directional temperature control. By setting rotatable converging plates on both sides of the guide vane, and controlling the rotation of the converging plates through the control unit on the guide vane, the linearly arranged guide vane and converging plates can form a regular V-shape or an inverted V-shape, further guiding the airflow to converge or diffuse to the surrounding area, thereby changing the width of the airflow and directing it to a designated location.

[0015] Furthermore, the control unit includes a control motor and two pulleys, and the output end of the control motor is equipped with a drive gear;

[0016] Two pulleys are connected to a driving gear and a clutch plate respectively. The two pulleys are equipped with a drive belt, and the other clutch plate is equipped with a driven gear. The driven gear meshes with the driving gear.

[0017] A control motor installed inside the guide vanes has a drive gear and a pulley mounted on its output axis. A driven gear is mounted on the rotating shaft of the clutch plate and guide vanes on one side, meshing with the drive gear. Another pulley is mounted on the rotating shaft of the clutch plate and guide vanes on the other side, and a transmission belt is fitted onto the two pulleys. When the control motor drives the drive gear and pulley on its output end to rotate, the drive gear drives the driven gear to rotate in the opposite direction, and the pulley drives the other pulley to rotate in the same direction through the transmission belt. This causes the two clutch plates to rotate in opposite directions, forming a V-shape or an inverted V-shape with the guide vanes.

[0018] Furthermore, the guide vanes are equipped with guide blocks;

[0019] The guide block has curved and flat surfaces;

[0020] The curved surface faces the direction of the driven gear.

[0021] By setting several guide blocks with the same orientation on the guide vane, the guide blocks have curved surfaces and flat surfaces. The curved surface of the guide block faces the driven gear. When the airflow reaches the end from the beginning of the curved surface and the flat surface at the same time, according to Bernoulli's principle, the air pressure on the curved surface side is less than the air pressure on the flat surface side, thus forming a pressure difference. This causes the airflow to flow towards the curved surface side, thereby causing the airflow to deflect towards the direction of flowing out of the test chamber. In turn, the airflow flows from the guide vane to the bottom and then flows towards the outlet.

[0022] Furthermore, the distribution unit includes a distribution box, an adjustment plate on the distribution box, a linear module on the distribution box, a moving end of the linear module connected to the adjustment plate, a guide plate on the distribution box, and a rotating motor on one side of the guide plate.

[0023] By installing a distribution box on one side of the air outlet of the test chamber on each layer, the airflow generated by the fan flows from the distribution box to the test chamber. By setting an adjustment plate at the inlet of the distribution box and a linear module on one side of the distribution box, the moving end of the linear module is fixed to the adjustment plate, so that the linear module can drive the adjustment plate to move, thereby changing the size of the distribution box inlet and thus changing the airflow into the test chamber. By setting a rotatable guide plate inside the distribution box and a rotating motor outside the distribution box on one side of the guide plate, the output end of the rotating motor is fixed to the rotating shaft of the guide plate, so that the rotating motor can drive the guide plate to rotate, thereby changing the direction of the airflow.

[0024] Furthermore, the heating unit includes a heating tube, and a heat-conducting plate is provided on the heating tube;

[0025] Heating strips are provided on the guide plate.

[0026] By installing a heat-conducting plate in front of the fan inlet, and installing heating tubes on the heat-conducting plate, the heating tubes are activated to heat the heat-conducting plate, thereby heating the airflow flowing through the heat-conducting plate and generating high-temperature airflow, which raises the temperature of the test chamber and simulates a high-temperature environment. By installing heating strips on the guide plate, the temperature of the airflow entering each layer of the test chamber can be further adjusted to achieve precise temperature control.

[0027] Furthermore, the detection mechanism includes a thermal imaging sensor, under which is a miniature wide-angle lens, and a shielding cover is installed outside the thermal imaging sensor.

[0028] By installing thermal imaging sensors in each test chamber and a miniature wide-angle lens below the thermal imaging sensors, the thermal imaging sensors can detect the temperature distribution of each test chamber. By installing a shield outside the thermal imaging sensors, interference from airflow is avoided.

[0029] Furthermore, the sealing mechanism includes an insulated door, and the box body and the connection between the insulated door;

[0030] Both the enclosure and the insulated door are equipped with sealing strips.

[0031] By installing an insulated door on the chamber, and with sealing strips on both the chamber and the insulated door, interference from the external environment can be avoided when the insulated door is closed, thus improving the accuracy of the test.

[0032] Furthermore, the control box is equipped with a display screen and an operation panel;

[0033] The insulated door is equipped with an observation window;

[0034] The enclosure is equipped with an alarm light.

[0035] By installing a display screen on the control box, it is easy to monitor the status of the power switch during each test. By installing an operation panel, it is easy to adjust the test parameters at any time. By installing an observation window on the insulation door, it is easy for the operator to directly observe the situation inside the test chamber. By installing an alarm light on the box, when the control system detects a non-compliant power switch or detects that the temperature inside the test chamber is out of control, the control system will activate the alarm light to alert the operator.

[0036] Compared with the prior art, the beneficial effects of the present invention are:

[0037] 1. By adjusting the angle between the guide vanes and the two side convergence plates through the adjustment unit, the airflow can freely switch between the figure-eight diffusion mode and the inverted figure-eight convergence mode. Thus, based on the temperature distribution detected by the thermal imaging sensor, the coverage width and blowing angle of the airflow can be dynamically adjusted to achieve fixed-point temperature control of a single or local power switch, avoiding temperature control dead zones that could lead to temperature differences affecting the test results.

[0038] 2. By using guide blocks on the surface of the guide vanes and utilizing Bernoulli's principle to create a low-pressure zone on the curved side of the airflow, the main airflow is actively deflected towards the outlet of the test chamber. This allows the airflow to flow smoothly to the exhaust channel after controlling the temperature of the power switch, significantly reducing airflow resistance.

[0039] 3. By configuring an adjustable airflow distribution box for each test chamber independently, the equipment can adjust the total airflow and airflow direction entering each chamber in real time and independently according to the difference in total heat generation of each power switch. By setting heat conduction plates and heating pipes in the main air duct to heat the airflow, combined with the real-time detection of the testing mechanism, the airflow entering each chamber can be adjusted separately again through the set heating strips, avoiding temperature difference problems in multiple test chambers, realizing temperature difference control between layers, and improving the stability of the test.

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Example: Figures 1-5 As shown, the present invention provides a technical solution: a high-frequency power switch aging test device that can realize intelligent temperature control. The aging test device includes a chamber 1, and a temperature control mechanism 2, a sealing mechanism 3 and a detection mechanism 4 are provided inside the chamber 1. A control box 5 is provided on one side of the chamber 1.

[0051] The test chamber 11 is provided in the middle of the chamber 1, the airflow channel 12 is provided on the side of the chamber 1, and the exhaust channel 13 is provided on the top of the chamber 1;

[0052] The temperature control mechanism 2 includes a guide vane 21, and an adjustment unit 22 is provided on the guide vane 21;

[0053] The test chamber 11 is equipped with a socket 6 and an aging test plate 7. The airflow channel 12 is equipped with a heating unit 23, a fan 24 and a distribution unit 25. The distribution unit 25 distributes the airflow into the test chamber 11. The adjustment unit 22 adjusts the angle of the guide vane 21 according to the result of the detection mechanism 4 to control the temperature in a directional manner.

[0054] By setting multiple partitions inside the chamber 1, the test chamber 11 of the chamber 1 is divided into multiple layers. Multiple sockets 6 and aging test plates 7 are set on each layer of the partition, so that the test equipment can test multiple high-frequency power switches at the same time. By inserting the input end of the power switch into the socket 6 and the output end of the power switch into the aging test plate 7, the power switch is subjected to aging test. The temperature inside the test chamber 11 is controlled by the temperature control mechanism 2. The fan 24 draws in air from the air inlet of the chamber 1 and makes the air flow into the airflow channel 12. The detection mechanism 4 controls the distribution unit 25 according to the temperature of each layer of the test chamber 11, and then distributes the air flow into each layer of the test chamber 11. The detection mechanism 4 detects the temperature distribution of each layer of the test chamber 11 and controls the adjustment unit 22 to change the angle of the guide vane 21, so that the air flow from the distribution unit 25 changes direction after hitting the guide vane 21, so that the air flow is directed to a specified direction for temperature control, thereby achieving the effect of intelligent temperature control. After the air flow passes through the test chamber 11, it flows out through the exhaust channel 13 at the top of the chamber 1.

[0055] like Figure 5 and Figure 6 As shown, the adjustment unit 22 includes an adjustment motor 221, and the output end of the adjustment motor 221 is provided with a rotating rod 222;

[0056] Converging plates 26 are provided on both sides of the guide vane 21;

[0057] The rotating rod 222 is connected to the guide vane 21. The guide vane 21 is equipped with a control unit 223, which controls the rotation of the two convergent plates 26.

[0058] By installing a rotating rod 222 on the guide vane 21, with one end of the rotating rod 222 rotatably connected to the housing 1 and the other end fixed to the regulating motor 221, the regulating motor 221 can drive the guide vane 21 to rotate along the axis of the rotating rod 222, thereby changing the angle of the guide vane 21. The airflow from the distribution unit 25 changes direction after hitting the guide vane 21. By changing the angle of the guide vane 21, it flows in different directions, thereby achieving directional temperature control. By setting rotatable converging plates 26 on both sides of the guide vane 21, and controlling the converging plates 26 to rotate through the control unit 223 on the guide vane 21, the linearly arranged guide vane 21 and converging plates 26 can form a regular V-shape or an inverted V-shape, further guiding the airflow to converge or diffuse to the surroundings, thereby changing the width of the airflow and directing it to a designated location.

[0059] like Figure 6 As shown, the control unit 223 includes a control motor 2231 and two pulleys 2233, and the output end of the control motor 2231 is provided with a drive gear 2232;

[0060] Two pulleys 2233 are respectively connected to a drive gear 2232 and a clutch plate 26. The two pulleys 2233 are provided with a drive belt 2234, and the other clutch plate 26 is provided with a driven gear 2235. The driven gear 2235 and the drive gear 2232 mesh.

[0061] The control motor 2231 installed inside the guide vane 21 has a drive gear 2232 and a pulley 2233 arranged along the output axis of the control motor 2231. A driven gear 2235 is arranged on the rotating shaft of the clutch plate 26 and the guide vane 21 on one side. The driven gear 2235 meshes with the drive gear 2232. Another pulley 2233 is arranged on the rotating shaft of the clutch plate 26 and the guide vane 21 on the other side. A transmission belt 2234 is sleeved on the two pulleys 2233. When the control motor 2231 drives the drive gear 2232 and the pulley 2233 on its output end to rotate, the drive gear 2232 drives the driven gear 2235 to rotate in the opposite direction. The pulley 2233 drives the other pulley 2233 to rotate in the same direction through the transmission belt 2234. This causes the two clutch plates 26 to rotate in opposite directions, so that they form a V-shape or an inverted V-shape with the guide vane 21.

[0062] like Figure 5 As shown, the guide vane 21 is provided with a guide block 27;

[0063] The guide block 27 is provided with a curved surface 271 and a flat surface 272;

[0064] The curved surface 271 faces the driven gear 2235.

[0065] By setting several guide blocks 27 with the same orientation on the guide vane 21, the guide block 27 has a curved surface 271 and a flat surface 272. The curved surface 271 of the guide block 27 faces the driven gear 2235. When the airflow reaches the end from the beginning of the curved surface 271 and the flat surface 272 at the same time, according to Bernoulli's principle, the air pressure on the side of the curved surface 271 is less than the air pressure on the side of the flat surface 272, thus forming a pressure difference, causing the airflow to flow towards the side of the curved surface 271, thereby causing the airflow to deflect towards the direction of flowing out of the test chamber 11, and then causing the airflow to flow from the guide vane 21 to the bottom and then flow towards the outlet.

[0066] like Figure 7 As shown, the distribution unit 25 includes a distribution box 251, an adjustment plate 252 on the distribution box 251, a linear module 253 on the distribution box 251, the moving end of the linear module 253 is connected to the adjustment plate 252, the distribution box 251 is provided with a guide plate 254, and a rotating motor 255 is provided on one side of the guide plate 254.

[0067] By installing a distribution box 251 on one side of the air outlet of the test chamber 11 on each layer, the airflow generated by the fan 24 flows from the distribution box 251 to the test chamber 11. By setting an adjustment plate 252 at the inlet of the distribution box 251, and by setting a linear module 253 on one side of the distribution box 251, with the moving end of the linear module 253 fixed to the adjustment plate 252, the linear module 253 can drive the adjustment plate 252 to move, thereby changing the size of the inlet of the distribution box 251 and thus changing the airflow into the test chamber 11. By setting a rotatable guide plate 254 inside the distribution box 251, and by setting a rotating motor 255 outside the distribution box 251 on one side of the guide plate 254, with the output end of the rotating motor 255 fixed to the rotating shaft of the guide plate 254, the rotating motor 255 can drive the guide plate 254 to rotate, thereby changing the direction of the airflow.

[0068] like Figure 3 and Figure 5 As shown, the heating unit 23 includes a heating tube 231, and a heat-conducting plate 232 is provided on the heating tube 231;

[0069] Heating strips 233 are provided on the guide plate 254.

[0070] By setting a heat-conducting plate 232 in front of the air inlet of the fan 24, and setting a heating tube 231 on the heat-conducting plate 232, the heating tube 231 is activated to heat the heat-conducting plate 232, thereby heating the airflow flowing through the heat-conducting plate 232, thereby generating a high-temperature airflow, raising the temperature of the test chamber 11, and simulating a high-temperature environment. By setting a heating strip 233 on the guide plate 254, the temperature of the airflow entering each layer of the test chamber 11 is further adjusted to achieve precise temperature control.

[0071] like Figure 8 As shown, the detection mechanism 4 includes a thermal imaging sensor 41, a miniature wide-angle lens 42 is provided under the thermal imaging sensor 41, and a shield 43 is provided outside the thermal imaging sensor 41.

[0072] By setting a thermal imaging sensor 41 in each test chamber 11, and a miniature wide-angle lens 42 under the thermal imaging sensor 41, the thermal imaging sensor 41 can detect the temperature distribution of each test chamber 11. By setting a shield 43 outside the thermal imaging sensor 41, interference from airflow is avoided.

[0073] like Figure 4 As shown, the sealing mechanism 3 includes an insulation door 31, and the box body 1 is connected to the insulation door 31;

[0074] Both the housing 1 and the insulated door 31 are equipped with sealing strips 32.

[0075] By setting an insulated door 31 on the chamber 1, and providing sealing strips 32 on both the chamber 1 and the insulated door 31, the insulated door 31 can prevent interference from the external environment to the test chamber 11 when closed, thereby improving the accuracy of the test.

[0076] like Figure 1 As shown, the control box 5 is equipped with a display screen 51 and an operation panel 52;

[0077] The insulated door 31 is equipped with an observation window 311;

[0078] An alarm light 8 is installed on the box 1.

[0079] By setting a display screen 51 on the control box 5, it is easy to monitor the status of the power switch during each test. By setting an operation panel 52, it is easy to adjust the test parameters at any time. By setting an observation window 311 on the insulation door 31, it is easy for the operator to directly observe the situation inside the test chamber 11. By setting an alarm light 8 on the box 1, when the control system of the control box 5 detects a non-compliant power switch or detects that the temperature inside the test chamber 11 is out of control, the control system controls the alarm light 8 to light up, thereby reminding the operator.

[0080] Working principle of the invention:

[0081] By inserting the power switch input terminal into socket 6 and the power switch output terminal into aging test plate 7, and closing the insulation door 31, the temperature distribution of each test chamber 11 is detected by thermal imaging sensors 41 installed in each test chamber 11. The thermal imaging sensors 41 transmit the temperature signal to the control system of control box 5. The control system controls the operation of each component. The linear module 253 on each distribution box 251 drives the adjustment plate 252 to move, changing the air inlet of the distribution box 251. The rotation motor 255 drives the guide plate 254 to rotate. The adjustment motor 221 drives the guide vane 21 to rotate along the axis of the rotating rod 222, thereby changing the angle of the guide vane 21. The control motor 2231 drives the drive gear. The rotation of pulleys 2232 and 2233 causes the drive gear 2232 to drive the driven gear 2235 to rotate in the opposite direction. The pulley 2233 drives another pulley 2233 to rotate in the same direction through the transmission belt 2234, thereby causing the two converging plates 26 to rotate in opposite directions, forming a V-shape or an inverted V-shape angle with the guide vanes 21. The fan 24 is started to draw airflow from the air inlet of the housing 1, and the heating tube 231 is started to heat the airflow. According to the temperature distribution detected by the thermal imaging sensor 41, the heating strip 233 on the guide plate 254 is started to further heat the airflow, thereby adjusting the temperature of the airflow for a second time and achieving precise control of the temperature of each test chamber 11.

[0082] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
