Description

Technical Field

[0001] This utility model relates to the field of active power filter heat dissipation technology, and more specifically, to a novel module APF lower air duct structure. Background Technology

[0002] An APF, or Active Power Filter, is a new type of power electronic device used for dynamically suppressing harmonics and compensating for reactive power. It can quickly track and compensate for harmonics of different magnitudes and frequencies. The term "active" refers to its ability to dynamically track and compensate for harmonics, as opposed to passive LC filters that can only passively absorb harmonics of fixed frequencies and magnitudes. An APF can sample the load current, separate harmonics and reactive power, control and actively output the magnitude, frequency, and phase of the current, and respond quickly to cancel the corresponding current in the load, achieving dynamic tracking compensation. Furthermore, it can compensate for both harmonics and reactive power imbalances, functioning as a power device.

[0003] Currently, APF modules generally have a protective shell on the outside, and the module itself is usually installed to fit the bottom of the shell. This means that the heat dissipation airflow can only circulate and dissipate heat on the top surface of the module, while the temperature of the bottom of the module in contact with the shell is difficult to reduce, resulting in uneven heat dissipation. At the same time, air cooling is often accompanied by the problem of dust accumulation on the dustproof structure on the air intake side, and conventional disassembly and cleaning methods are inefficient and require shutdown. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a novel modular APF lower air duct structure to solve the above-mentioned background technical problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution;

[0006] A novel modular APF lower air duct structure includes a housing. Two bottom ventilation frames are fixedly installed inside the housing. A lower heat dissipation fin is fixedly connected to the top of the two bottom ventilation frames. An APF module is fixedly installed on the top of the lower heat dissipation fin, and an upper heat dissipation fin is fixedly connected to the top of the APF module. An air outlet is provided on the left side of the housing. A cooling fan is fixedly installed inside the housing. An air inlet is provided on the right side of the housing. Three dustproof mesh plates arranged in contact are inserted inside the air inlet. A locking component is fixedly installed on the housing, and the locking component presses and engages with the dustproof mesh plates.

[0007] As a further description of the above technical solution: the locking component includes a rotating screw, a movable frame and two rubber wheels. One end of the rotating screw passes through and is threaded to the inside of the housing. The end of the rotating screw is rotatably connected to the movable frame. The two rubber wheels are respectively installed to the right ends of the movable frame. The rubber wheels extend into the inside of the air inlet and contact the dustproof mesh plate on the left side.

[0008] As a further description of the above technical solution: the right end of the housing is provided with a crossbar integrally formed with the housing, and the end of the rotating screw is threadedly connected to the crossbar.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0022] Please see Figure 1-5 In this utility model, a novel modular APF lower air duct structure includes a housing 1. Two bottom ventilation frames 2 are fixedly installed inside the housing 1. A lower heat dissipation fin 3 is fixedly connected to the top between the two bottom ventilation frames 2. An APF module 4 is fixedly installed on the top of the lower heat dissipation fin 3. An upper heat dissipation fin 5 is fixedly connected to the top of the APF module 4. An air outlet 6 is opened on the left side of the housing 1. A cooling fan 7 is fixedly installed inside the housing 1. An air inlet 8 is opened on the right side of the housing 1. Three dustproof mesh plates 9 arranged in contact are inserted inside the air inlet 8. A locking member 10 is fixedly installed on the housing 1, and the locking member 10 presses and engages with the dustproof mesh plates 9.

[0023] In this invention, the housing 1 serves as the external main body, and the APF module 4 is fixedly installed on the bottom ventilation frame 2, suspending it between the housing 1 and the housing 1. When the equipment is running, the cooling fan 7 is activated to exhaust the internal hot air through the left air outlet 6, creating a negative pressure adsorption effect inside the housing 1. External cold air is then drawn into the housing 1 through the right air inlet 8. The external air is then diverted through the top and bottom of the APF module 4, achieving contact heat exchange between the upper and lower heat dissipation fins 5 and 3 on the APF module 4, carrying away heat and providing a more comprehensive contact area. As the equipment runs, dust accumulates on the right-side dustproof mesh plate 9, requiring cleaning. At this time, the rightmost dustproof mesh plate 9 is simply pulled out along the open side of the air inlet 8, and then the locking piece 10 is tightened to allow the remaining two dustproof mesh plates 9 to be inserted. The clamping mechanism ensures the equipment operates normally and facilitates loading and unloading. After cleaning, the dustproof mesh 9 is inserted into the leftmost position by loosening the locking piece 10, and then the locking piece 10 is tightened to relock the three dustproof meshes 9. This allows the device to achieve more sufficient contact between airflow and the module body, improving heat dissipation. At the same time, it enables flexible non-stop loading and unloading of the dustproof structure on the air inlet side, facilitating cleaning and switching. This solves the problems in the existing technology where the module itself is usually installed against the bottom surface of the shell, which means that the heat dissipation airflow can only circulate and dissipate heat on the upper surface of the module, while the temperature of the bottom of the module in contact with the shell is difficult to reduce, resulting in uneven heat dissipation. In addition, air cooling often results in dust accumulation on the dustproof structure on the air inlet side, and conventional disassembly and cleaning methods are inefficient and require shutdown.

[0024] Please see Figure 2 The locking component 10 includes a rotating screw 101, a movable frame 102, and two rubber wheels 103. One end of the rotating screw 101 passes through and is threaded to the inside of the housing 1. The end of the rotating screw 101 is rotatably connected to the movable frame 102. The two rubber wheels 103 are respectively installed at the right ends of the movable frame 102. The rubber wheels 103 extend into the inside of the air inlet 8 and contact the dustproof mesh plate 9 on the left side.

[0025] In this utility model, rotating the screw 101 drives the movable frame 102 to move synchronously, thereby driving the two rubber wheels 103 to move synchronously, pressing the dustproof mesh 9 to make it stable. When disassembling the dustproof mesh 9, simply loosen the screw. The operation is flexible and convenient.

[0026] Please see Figure 2 and Figure 4 The right end of the housing 1 is provided with a crossbar 11 integrally formed with the housing 1, and the end of the rotating screw 101 is threadedly connected to the crossbar 11.

[0027] In this invention, the crossbar 11 improves the installation and support effect of the rotating screw 101.

[0028] Please see Figure 2 The dustproof mesh plate 9 has two parallel guide grooves 91 on its left side, and the rubber wheel 103 extends into the interior of the guide grooves 91 and contacts the interior of the guide grooves.

[0029] In this invention, the guide groove 91 reduces resistance when the dustproof mesh plate 9 is pulled out and inserted, making the operation more flexible.

[0030] Please see Figure 5 The dustproof mesh plate 9 has a through groove 92 that fits with the crossbar 11, and an inner sealing gasket 93 is fixedly connected to the inner wall of the through groove 92.

[0031] In this invention, the dustproof mesh plate 9 and the crossbar 11 are fitted together by the through groove 92, and the inner sealing gasket 93 is used to prevent dust from entering through the gaps, thereby improving the dustproof effect.

[0032] Please see Figure 4 and Figure 5 Among them, the front side of the dustproof mesh plate 9 is fixedly connected with a handle strip 94.

[0033] In this utility model, the handle strip 94 makes it easy to pick up and put down the dustproof mesh plate 9, and facilitates operation.

[0034] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
