With the development of modern industry, VFDs are increasingly widely used, especially in large factories, refrigeration systems, and automated control systems, where they play a crucial role.

[0003] Traditional inverter mounting frames are typically fixed designs, resulting in slow airflow inside the frame. This can easily lead to overheating of the inverter during prolonged operation, affecting its normal function. Furthermore, the installation and disassembly of traditional mounting frames are cumbersome, making maintenance and parts replacement inconvenient and resulting in long maintenance cycles. Therefore, a modular inverter mounting frame is proposed to address the aforementioned problems. Utility Model Content

[0026] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0027] Reference Figures 1-3 As shown, a modular inverter mounting frame includes a mounting base 1. A rear shell 2 is fixedly connected to the front end of the mounting base 1. A front shell 3 is hinged to the front end of the rear shell 2. Three evenly distributed locking blocks 301 are fixedly connected to the lower end of the front shell 3. Three evenly distributed elastic hooks 6 are fixedly connected to the lower end of the rear shell 2. The elastic hooks 6 are engaged inside the locking blocks 301. A fixed grille 7 is fixedly connected to the bottom inner side of the rear shell 2 through a heightening block. Ventilation slots 201 are provided through both the left and right ends of the rear shell 2. Fixed frames 4 are fixedly connected to the left and right ends of the rear shell 2 at the corresponding positions of the ventilation slots 201. A sliding groove 401 is provided at the upper end of the fixed frame 4. A fixed block 402 is slidably connected to the inner side of the sliding groove 401. A heat dissipation component 5 is provided inside the sliding groove 401.

[0028] Furthermore, the ventilation slot 201 is used to dissipate heat from the frequency converter, and the inner side of the fixed grille 7 is used to place the frequency converter. The inner dimensions of the fixed grille 7 are the same as the dimensions of the frequency converter to be installed. A certain gap is left between the fixed grille 7 and each inner wall of the rear shell 2, so that the air entering the interior of the rear shell 2 through the ventilation slot 201 can circulate better, thereby achieving a better heat dissipation effect.

[0029] Furthermore, the hinged design of the front housing 3 allows it to rotate and open, facilitating the placement and removal of the inverter. The center of the locking block 301 is hollow. When the front housing 3 is rotated to close, the locking block 301 will first squeeze the elastic hook 6 to deform. After the front housing 3 is completely closed, the elastic hook 6 will spring back and lock into the hollow structure of the locking block 301, thereby fixing the front housing 3.

[0030] Reference Figures 1-6 As shown, the heat dissipation assembly 5 includes a fixed seat 501 that is slidably connected inside the slide groove 401. A heat dissipation fan 502 is provided on the inner side of the fixed seat 501, and a filter screen 503 is provided on the outer side of the fixed seat 501.

[0031] Furthermore, the lower end of the fixing block 402 abuts against the upper end of the fixing seat 501. Both the fixing block 402 and the fixing frame 4 have a connecting hole 403 through them on their outer sides. The connecting hole 403 is threaded with a fixing screw 404. The fixing block 402 is used to limit and fix the fixing seat 501 to prevent it from shaking during use. By rotating and removing the fixing screw 404, it can be removed from the connecting hole 403, thereby allowing the fixing block 402 and the fixing seat 501 to be disassembled.

[0032] Furthermore, the output end of one of the cooling fans 502 faces the inside of the rear shell 2 to introduce external air into the interior of the rear shell 2, while the output end of the other cooling fan 502 faces the outside of the rear shell 2 to blow the air inside the rear shell 2 to the outside. The cooperation of the two cooling fans 502 can accelerate the airflow rate inside the rear shell 2 and significantly improve the heat dissipation effect.

[0033] Furthermore, mounting grooves 506 are provided at the four corners of the outer side of the mounting base 501. A first magnetic block 504 is fixedly connected inside the mounting groove 506. A second magnetic block 505 is fixedly connected to the side of the filter screen 503 near the mounting base 501 at the corresponding position of the first magnetic block 504. The second magnetic block 505 is inserted into the inside of the filter screen 503. The magnetic poles of the first magnetic block 504 and the second magnetic block 505 are opposite. The filter screen 503 is attracted to the outside of the mounting base 501 by the first magnetic block 504 and the second magnetic block 505.

[0034] Furthermore, the filter screen 503 is fixed to the outside of the mounting base 501 by magnetic attraction. When the filter screen 503 needs to be cleaned, only a certain external force needs to be applied so that the filter screen 503 overcomes the magnetic force of the two magnetic blocks, and the filter screen 503 can be quickly removed, which simplifies the installation and disassembly process of the filter screen 503 and facilitates maintenance.

[0035] Furthermore, the heat dissipation component 5 can be disassembled independently, and the filter 503 can be disassembled separately from the heat dissipation component 5. This allows for separate disassembly and replacement of the heat dissipation component 5 when it is damaged, making it more convenient.

[0036] Furthermore, a through slot 302 is provided at the front end of the front shell 3. The position of the through slot 302 corresponds to the plug-in panel of the frequency converter, which can provide a path for removing the plug-in panel when the front shell 3 is closed.

[0037] Furthermore, the front end of the front shell 3 is provided with an arc-shaped outlet 303 at the upper end of the through groove 302. The arc-shaped outlet 303 provides a force point that contacts the surface of the plug-in panel when the plug-in panel is removed, thus facilitating the removal of the plug-in panel.

[0038] Furthermore, the mounting base 1 has four through holes 101 at the front end corners. The mounting holes 101 are used to install threaded connectors. By aligning the mounting holes 101 with the reserved holes on the cabinet and fastening them with threaded connectors, the frequency converter can be installed in the cabinet.

[0039] Working principle: In use, first pull the front cover 3 outward to separate the locking block 301 from the elastic hook 6. At this time, the front cover 3 can be rotated and opened. After opening the front cover 3, place the frequency converter in the fixed grid 7 and align the plug-in panel with the direction of the front cover 3. Then close the front cover 3. Next, insert the fixing seat 501 into the slide groove 401 and press the fixing block 402 on the upper end of the fixing seat 501. At the same time, install the fixing screw 404 in the connection hole 403 to fix the fixing seat 501. After the fixing seat 501 is installed, connect the cooling fan 502 to the power supply to ensure that it can operate normally. Then align the fixing hole 101 with the reserved hole on the cabinet and tighten it with the threaded connector. Install the frequency converter in the cabinet. When the frequency converter is working normally, one cooling fan 502 introduces external air into the rear cover 2, and the other cooling fan 502 exhausts the air inside the rear cover 2, forming an air circulation. The two cooling fans 502 work together to enhance airflow and improve heat dissipation.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
