Description

Technical Field

[0001] This utility model belongs to the field of test cabinet technology, and in particular relates to a quick-assembly MNS test platform cabinet. Background Technology

[0002] When conducting tests on power electronic equipment, the component under test (DUT) needs to be placed in a separate compartment, and its status during the test needs to be observed.

[0003] During test platform operation, heat dissipation design is required for heat-generating components. Power electronic components experience losses during operation, most of which are converted into heat. In practical applications, high-power devices, such as IGBTs, generate significant losses, typically manifesting as heat. To ensure proper component operation, the power dissipation must not exceed the maximum allowable power dissipation Ptot (rated 1660W, at 25°C), and the IGBT junction temperature Tvj must not exceed its maximum value Tvjmax (150°C). Therefore, the cabinet design must incorporate appropriate heat dissipation devices to conduct heat to the external environment. A search revealed patent application number 201721560962.8, which discloses a test platform cabinet structure based on the MNS cabinet type. The structure consists of a cabinet frame and cabinet panels. The cabinet is divided into multiple compartments by partitions. The cabinet is divided into front and rear parts. The front part of the cabinet, from top to bottom, consists of an IGBT compartment, a testing compartment, and a lower compartment. The lower compartment is divided into a power distribution compartment and a power electronic component compartment on the left and right. The rear part of the frame is a planar inductor compartment. The partitions separating the compartments are equipped with through holes. Each compartment is equipped with an independent cabinet door. The top of the cabinet is equipped with an air outlet, which corresponds to and is connected to the IGBT compartment. The cabinet panels and doors corresponding to the IGBT compartments are equipped with ventilation openings.

[0004] However, during actual use, the applicant found that its test platform cabinet is a monolithic structure that cannot be flexibly disassembled, and due to its large overall structure, it is inconvenient to transport and move it. In view of this, we propose an MNS test platform cabinet that can be quickly assembled. Utility Model Content

An observation window 4 is provided on the front door of the test control cabinet 2 for observing the status of the test components inside the test cabinet 3. Lower connecting seats 11 are symmetrically fixedly connected to the top of the test power cabinet 1, and connecting plugs are symmetrically opened on the top and bottom of the test control cabinet 2. Hole 21, the bottom of the test cabinet 3 is symmetrically and fixedly connected to the upper connecting seat 10, the two sides of the test control cabinet 2 are symmetrically and elastically connected to the U-shaped limit frame 7 by spring 9, the two sides of the test control cabinet 2 are symmetrically and fixedly provided with limit support plates 22, the middle of the front side of the U-shaped limit frame 7 is fixedly provided with a guide rod 71, the front end of the guide rod 71 moves through the limit support plate 22 and is fixedly provided with a limit circular plate 711, the spring 9 is sleeved on the guide rod 71 between the limit circular plate 711 and the limit support plate 22, the two U-shaped limit frames 7 are fixedly connected by a connecting beam 8, the middle of the connecting beam 8 is provided with a hand groove 81. The hand slot 81 is used for manual pulling of the connecting beam 8 to move the U-shaped limiting frame 7 backward. The two lower connecting seats 11 are limited in the two lower connecting holes 21 by the lower part of the U-shaped limiting frame 7. The front ends of the lower part of the two U-shaped limiting frames 7 are respectively inserted into the limiting slots opened on the two lower connecting seats 11. The two upper connecting seats 10 are limited in the two upper connecting holes 21 by the upper part of the U-shaped limiting frame 7. The front ends of the upper part of the two U-shaped limiting frames 7 are respectively inserted into the limiting slots opened on the two upper connecting seats 10. A control panel is fixedly installed on the cabinet door on the front side of the test control cabinet 2. 5. By manually pulling the U-shaped limit bracket 7 backward to compress the spring 9, the test control cabinet 2 is stacked on top of the test power cabinet 1, so that the lower connecting seat 11 is inserted into the lower connecting socket 21. Then, the test cabinet 3 is stacked on top of the test control cabinet 2, so that the upper connecting seat 10 is inserted into the upper connecting socket 21. Finally, under the elastic force of the spring 9, the U-shaped limit bracket 7 is driven to reset and move, limiting the upper connecting seat 10 and the lower connecting seat 11 in the connecting socket 21. This completes the rapid assembly of the MNS test platform cabinet, which is convenient to operate and easy to disassemble, transport and transfer.

[0023] An axial flow fan 12 is fixedly installed on the rear side of the test cabinet 3. An upper air inlet pipe 31 is also fixedly installed on the rear side of the test cabinet 3. The upper end of the upper air inlet pipe 31 is connected to the interior of the test cabinet 3, and the lower end of the upper air inlet pipe 31 is connected to the air supply end of the axial flow fan 12. A connecting branch pipe 311 is fixedly installed at the bottom of the air supply end of the axial flow fan 12. A lower air inlet pipe 23 is fixedly installed on the rear side of the test control cabinet 2. The upper end of the lower air inlet pipe 23 is connected to the lower end of the connecting branch pipe 311 through a connecting pipe 13, and the lower end of the lower air inlet pipe 23 is connected to the interior of the test control cabinet 2. Heat dissipation windows 14 are opened on both sides of the test control cabinet 2 and the test cabinet 3. By driving the axial flow fan 12 to rotate, air can be quickly supplied to the interior of the test cabinet 3 and the test control cabinet 2, and exhaust heat can be dissipated through the heat dissipation windows 14. This can effectively prevent the internal temperature of the test control cabinet 2 and the test cabinet 3 from becoming too high, and better ensure the smooth testing of the components inside the test cabinet 3.

[0024] Working Principle: In use, the test power cabinet 1 can be placed stably in the desired position. Then, the connecting beam 8 can be manually pulled backward to move the U-shaped limit frame 7 backward. The backward movement of the U-shaped limit frame 7 moves the guide rod 71 and the limiting plate 711 backward, compressing the spring 9 through the limiting plate 711, causing the front end of the U-shaped limit frame 7 to move away from the connecting socket 21. Next, the test control cabinet 2 is stacked on top of the test power cabinet 1, with the lower connecting seat 11 passing through the lower connecting socket 21, keeping the U-shaped limit frame 7 stationary. Then, the test cabinet 3 is stacked on top of the test control cabinet 2, with the upper connecting seat 10 passing through the two upper connecting sockets 21. Finally, the connecting beam 8 is released. At this point, under the elastic force of the spring 9, the U-shaped limit frame 7 can be moved backward. The front reset movement is completed, and the lower front end of the U-shaped limit frame 7 is inserted into the limit slot on the lower connecting seat 11, and the upper front end of the U-shaped limit frame 7 is inserted into the limit slot on the upper connecting seat 10. This completes the rapid assembly of the MNS test platform cabinet. During the testing of the components placed inside the test cabinet 3, the axial flow fan 12 can be driven to rotate through the control panel 5. The rotation of the axial flow fan 12 can deliver air into the test cabinet 3 and the test control cabinet 2 through the upper air inlet pipe 31 and the lower air inlet pipe 23, respectively. This allows the heat inside the test cabinet 3 and the test control cabinet 2 to be discharged through the heat dissipation window 14, thereby quickly dissipating heat inside the test cabinet 3 and the test control cabinet 2 and preventing the components inside the test cabinet 3 and the test control cabinet 2 from overheating due to operation.
