[0002] Variable frequency drives (VFDs), as important power control devices, are widely used in industrial automation, motor drives, and energy management. Their main function is to precisely control motor speed and output power by adjusting the power supply frequency, thereby improving equipment operating efficiency and reducing energy consumption. However, in practical applications, the installation and maintenance of VFDs often face numerous challenges. Traditional VFDs typically employ an integrated design, resulting in a complex structure and large size, requiring significant time and manpower for fixing, wiring, and debugging during installation. Furthermore, existing VFDs are mostly assembled in a fixed structure, lacking modular design, making disassembly, replacement, and maintenance cumbersome, especially in space-constrained scenarios or those requiring frequent adjustments.

[0003] Meanwhile, existing frequency converters typically require specialized tools and skilled technicians for installation, which not only increases installation costs but also prolongs the time it takes for the equipment to be put into use. Especially in special application scenarios, such as temporary projects or emergency replacement needs, the installation efficiency of traditional frequency converters is insufficient to meet actual requirements. Therefore, designing a frequency converter that is easy to install, disassemble, and maintain has become a pressing technical challenge. This invention aims to provide a simple and easy-to-operate frequency converter solution through a modular and assembly-based design concept, significantly improving installation efficiency and reducing maintenance difficulty.

Detailed Implementation

[0023] This utility model provides an easy-to-install modular frequency converter, which solves the problems of complex installation and difficult maintenance of traditional frequency converters through modular design and innovative installation structure, while improving heat dissipation efficiency and operational safety. The following is in conjunction with the appendix... Figure 1 To be continued Figure 3The specific embodiments of this utility model are described in detail with reference to the component numbers marked in the accompanying drawings.

[0024] like Figure 1 As shown, the modular frequency converter of this utility model includes a modular frame 1, a heat dissipation assembly 2, and an electrical connection assembly 3. The modular frame 1, as the core support structure of the entire frequency converter, is designed with ease of installation and expandability in mind. The modular frame 1 consists of a main housing 11, a pair of slide rails 12, several positioning pins 13, a pair of latches 14, and a back plate 15. The main housing 11 is a rectangular box structure with ventilation slots on both its left and right side walls to enhance airflow and aid heat dissipation. The slide rails 12 are symmetrically arranged on the inner side walls of the main housing 11 near the top and bottom ends. Several positioning pins 13 are evenly distributed on the inner side walls of the slide rails 12, which are used to fix the positions of the heat dissipation assembly 2 and the electrical connection assembly 3. The latches 14 are symmetrically arranged on the front side walls of the main housing 11 near the top and bottom ends, and are used to cooperate with the back plate 15 to achieve quick disassembly and installation. The back plate 15 is detachably connected to the rear side wall of the main housing 11 via the latch 14. The back plate 15 is provided with mounting holes, and the user can fix the back plate 15 to the wall or equipment surface with bolts to complete the installation of the entire frequency converter.

[0025] The heat dissipation component 2 is designed to improve the heat dissipation performance of the inverter and prevent dust from entering the main housing 11. For example... Figure 3 As shown, the heat dissipation assembly 2 includes a heat sink 21, several heat-conducting columns 22, a pair of fans 23, a pair of filters 24, and a pair of clips 25. The heat sink 21 has a rectangular plate structure, with its outer side wall fitting against the side wall of the main housing 11 to ensure efficient heat transfer to the external environment. One end of each heat-conducting column 22 is fixed to the inner side wall of the heat sink 21, and the other end extends into the inner side of the main housing 11. The heat-conducting columns 22 are made of high thermal conductivity material and are fixedly connected to the heat sink 21 by welding to ensure that heat can be quickly conducted from the inside of the main housing 11 to the heat sink 21. The fans 23 are symmetrically embedded in the middle of the heat sink 21. The fans 23 are connected to the control circuit inside the main housing 11 via wires. Their start and stop are controlled by a temperature sensor inside the main housing 11. When the internal temperature exceeds a set threshold, the fans 23 automatically start to accelerate airflow. The filters 24 cover the outside of the fans 23 and are used to filter dust and impurities in the air entering the main housing 11, thereby extending the service life of the equipment. Clips 25 are symmetrically arranged at the upper and lower ends of the heat sink 21. The clips 25 cooperate with the slide rail 12 to enable quick assembly and disassembly of the heat sink 21. In addition, a sealing gasket is provided between the heat sink 21 and the main housing 11 to prevent dust from entering the interior of the main housing 11, thereby further improving the protective performance of the equipment.

[0026] The electrical connection assembly 3 is designed to enable quick insertion and removal and precise positioning, thereby simplifying the installation and maintenance process of the terminals. As shown in the figure, the electrical connection assembly 3 includes a base 31, several terminals 32, a pair of elastic clips 33, a pair of guide rods 34, and a pair of limiting blocks 35. The base 31 is a rectangular plate structure that is movably inserted into the bottom of the main housing 11. The terminals 32 are evenly distributed on the upper surface of the base 31 for connecting external circuits. The elastic clips 33 are symmetrically arranged on the left and right side walls of the base 31. When the base 31 is inserted into the main housing 11, the elastic clips 33 are compressed and contracted. When the positioning pin 13 reaches the clip position, the elastic clips 33 pop out and cooperate with the positioning pin 13 to fix the base 31. The guide rods 34 are symmetrically arranged at the front and rear ends of the base 31. The guide rods 34 cooperate with the guide grooves at the bottom of the main housing 11 to ensure that the base 31 can maintain horizontal movement when inserted into the main housing 11, avoiding poor contact between the terminals 32 and the circuit inside the main housing 11. The limiting block 35 is fixedly installed at the end of the guide rod 34 to prevent the base 31 from detaching from the main housing 11, thereby improving the reliability of the installation.

[0027] In practical applications, the modular frequency converter of this invention offers significant ease of operation and adaptability. For example, in industrial automation scenarios, users need to install the frequency converter on the surface of equipment or on a wall. First, the user can fix the back plate 15 to the target position with bolts, and then connect the main housing 11 to the back plate 15 via the latch 14 to complete the installation of the modular frame 1. Next, the user can quickly install the heat dissipation component 2 onto the side wall of the main housing 11 using the clip 25 and the slide rail 12, ensuring that the heat dissipation plate 21 fits tightly against the main housing 11. Subsequently, the user inserts the base 31 of the electrical connection component 3 into the bottom of the main housing 11 along the guide groove, and the elastic clip 33 cooperates with the positioning pin 13 to fix the base 31. Finally, the user connects the external circuit to the terminal block 32 to complete the entire installation process of the frequency converter. Since all components adopt a modular design, users do not need to use additional tools when maintaining or replacing parts; they can quickly disassemble the relevant components by simply reversing the above steps.

[0028] The heat dissipation performance of this invention is significantly improved. During operation, the heat generated by the electronic components inside the main housing 11 is conducted to the heat sink 21 through the heat conduction column 22, and the heat sink 21 dissipates the heat to the external environment. When the internal temperature of the main housing 11 rises to a set threshold, the temperature sensor triggers the fan 23 to start, and the fan 23 accelerates airflow, further improving heat dissipation efficiency. The filter 24 effectively filters dust and impurities in the air entering the main housing 11, preventing dust accumulation from affecting equipment performance. In addition, the design of the sealing gasket ensures the seal between the heat sink 21 and the main housing 11, preventing dust from entering the interior of the main housing 11, thereby extending the service life of the equipment.

[0029] The electrical connection assembly 3 of this invention achieves quick insertion and removal and precise positioning through the design of the elastic clip 33 and the guide rod 34. During installation, the user only needs to insert the base 31 into the bottom of the main housing 11 along the guide groove, and the elastic clip 33 automatically engages with the positioning pin 13 to lock it in place, completing the installation without additional tools. The engagement of the guide rod 34 with the guide groove ensures that the base 31 moves horizontally during insertion, preventing poor contact between the wiring terminal 32 and the circuit inside the main housing 11. The design of the limiting block 35 further improves the reliability of installation, preventing the base 31 from detaching from the main housing 11 due to external forces.

[0030] In summary, this utility model's modular inverter solves the problems of complex installation and difficult maintenance associated with traditional inverters through its modular design and innovative installation structure, while simultaneously improving heat dissipation efficiency and operational safety. Its modular frame 1 design makes installation and disassembly more convenient, the high-efficiency heat dissipation structure of the heat dissipation component 2 significantly improves the equipment's heat dissipation performance, and the quick-plug and precise positioning design of the electrical connection component 3 greatly enhances operational convenience. This utility model is applicable to various application scenarios and has high practicality and promotional value.
