Description

Technical Field

[0001] The utility model relates to the technical field of frequency converter installation, in particular to a frequency converter installation structure. Background Art

[0002] A frequency converter (VFD) is a power electronic device primarily used to regulate and control the speed of an electric motor. It adjusts the motor's operating speed by varying the power supply frequency, achieving precise control of the motor. VFDs offer energy savings, a wide speed regulation range, high starting torque, and stable operation. They are widely used in industrial production, elevators, air conditioners, water pumps, fans, and other fields.

[0003] During the actual installation of the inverter, we may encounter some common problems. If these problems are not solved in time, they may cause delays in the installation process and even affect the normal operation of the inverter.

[0004] When installing an inverter, we first need to ensure that it fits perfectly with the intended mounting surface. However, sometimes we find that the screw holes are not positioned accurately. This may be due to a discrepancy between the design drawings and the actual mounting surface, or due to insufficient machining precision. If the screw holes are not positioned accurately, the inverter may not be installed correctly, resulting in wiring difficulties or the device not being fixed in the correct position, which in turn affects the inverter's heat dissipation and overall stability.

[0005] Another common problem is screw hole damage, which can manifest as an oversized hole diameter or damaged hole walls. Oversized holes can prevent the bolt from being securely fastened, while damaged hole walls can prevent the bolt from tightening properly or even cause further damage during the tightening process. This damage can be caused by improper use of installation tools, accidental impact during installation, or defects in the material itself. Damaged screw holes not only make it difficult to secure the inverter but can also affect its long-term stable operation, as an unstable connection can cause vibration and noise, and even lead to poor electrical contact.

[0006] The main purpose of the utility model is to provide a frequency converter installation structure, which can effectively solve the problems raised in the background technology.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A frequency converter installation structure includes a frequency converter housing and a control button, wherein the control button is located at the front end of the frequency converter housing;

[0009] Side frames are provided on both sides of the rear end of the inverter housing, and recessed grooves are provided at the ends of the two side frames. First mounting holes are provided on the walls of the recessed grooves, and bolts are inserted into the first mounting holes to fix the inverter.

The connection between the heat conducting sheet and the heat dissipating fins is coated with thermal grease, and the connection between the heat dissipating fins and the inverter housing is coated with sealant.

[0013] As a further preferred embodiment of the present invention, the U-shaped movable frame is mounted in a storage cavity formed by the heat dissipation fins and the side frame, and the upper end of the U-shaped movable frame in the stored state is flush with the surface of the side frame and the inverter housing;

[0014] As a further preferred embodiment of the present invention, the embedded limit block is connected to the U-shaped movable frame by bolts, and the edge of the embedded limit block is designed to be arc-shaped.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In this utility model, by providing a first mounting hole in the recessed groove of the side frame, the stability and reliability of the inverter during installation are ensured. The first mounting hole and the second mounting hole have the same diameter, allowing users to select different mounting holes for fixing according to actual needs, simplifying the installation process and improving the applicability and convenience of the inverter.

[0018] Furthermore, by forming a cavity between the two side frames and installing multiple cooling fins, the heat dissipation area is increased, helping to improve the inverter's heat dissipation efficiency. Sealant is applied to the connection between the cooling fins and the inverter housing to ensure a good seal, preventing dust and moisture from entering and protecting the inverter's internal components. Thermal grease is applied to the connection between the cooling fins and the heat conducting plate to improve heat conduction efficiency, helping to more effectively transfer heat from the inverter interior to the external environment.

[0019] Furthermore, when stored, the upper end of the U-shaped movable frame is flush with the side frame and the inverter housing, giving the inverter a clean and space-saving appearance.

The curved edges of the embedded limit blocks facilitate user operation and adjustment, increasing the convenience of installation and adjustment. This design not only improves the performance and reliability of the inverter but also takes into account the actual needs of users, making the product more user-friendly and practical.

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1 - Figure 4 The figure shows an inverter mounting structure designed to provide an inverter that is easy to install and has good heat dissipation. The structure includes an inverter housing 1, control buttons 2, and a series of components for mounting and heat dissipation. The control buttons 2 are located at the front of the inverter housing 1 for easy user operation.

[0027] Side frames 3 are provided on either side of the rear end of the inverter housing 1. These frames not only provide support but also feature recessed grooves 4 at their ends. First mounting holes 5 are defined in the walls of these recessed grooves 4, allowing bolts to be inserted into these holes to secure the inverter. This design ensures the inverter's stability and reliability during installation.

[0028] A cavity is formed between the two side frames 3, in which a plurality of heat dissipation fins 6 are provided. These heat dissipation fins 6 not only increase the heat dissipation area, but also help improve the heat dissipation efficiency of the inverter. A clamping cavity 7 is formed between two adjacent heat dissipation fins 6, which provides installation space for the U-shaped movable frame 10. The inner end of the U-shaped movable frame 10 is connected to an embedded limit block 9, and the opposing heat dissipation fin 6 is provided with a limit slide 8 adapted to the embedded limit block 9. By moving the embedded limit block 9 up and down along the limit slide 8, the pull-up distance of the U-shaped movable frame 10 can be adjusted, thereby achieving an expansion of the number of mounting holes and a change in position.

[0029] The inverter housing 1 and side frames 3 are integrally designed, with two side frames 3 symmetrically positioned at the rear end of the inverter housing 1. The side frames 3 have a U-shaped cross-section, which is both aesthetically pleasing and provides excellent structural strength. Multiple heat sink fins 6 are evenly spaced at the rear end of the inverter housing 1.

The connection between the heat sink fins and the inverter housing 1 is coated with thermal grease to improve heat transfer efficiency, while the connection between the heat sink fins 6 and the inverter housing 1 is coated with sealant to ensure a good seal.

[0030] The U-shaped movable frame 10 is mounted within the storage cavity formed by the heat sink fins 6 and the side frame 3. When stowed, the upper end of the U-shaped movable frame 10 is flush with the side frame 3 and the inverter housing 1, creating a clean, space-saving appearance. The embedded stopper 9 is bolted to the U-shaped movable frame 10. Its curved edge facilitates user operation and adjustment.

[0031] The first mounting hole 5 and the second mounting hole 11 have the same diameter and are both screw holes. This design allows for flexibility during inverter installation, allowing users to select different mounting hole locations for mounting according to their needs. This design not only simplifies the installation process but also improves the inverter's usability and convenience.

This can achieve the expansion of the number of mounting holes and the change of their positions. Use bolts to insert into the first mounting hole 5 or the second mounting hole 11 to fix the inverter. Ensure the stability and reliability of the inverter during installation. Confirm that the inverter housing 1 and the side frames 3 are of an integrated design, and the two side frames 3 are symmetrically distributed at the rear end of the inverter housing 1 .

[0033] Ensure that multiple heat sink fins 6 are evenly distributed at the rear end of the inverter housing 1 and extend through the inverter housing 1 to the inner cavity of the inverter housing 1. Confirm that the heat sink fins 6 are connected to the heat conducting plate in the inner cavity of the inverter housing 1. Apply thermal grease at the connection between the heat sink fins 6 and the heat conducting plate to improve the heat conduction efficiency. Apply sealant at the connection between the heat sink fins 6 and the inverter housing 1 to ensure good sealing performance. Ensure that the upper end of the U-shaped movable frame 10 is flush with the surface of the side frame 3 and the inverter housing 1 in the storage state. Ensure that the edge of the embedded limit block 9 is designed to be arc-shaped for easy user operation and adjustment. The installation of the inverter can be completed, and the U-shaped movable frame 10 can be adjusted as needed to increase the number of mounting holes and change the position.
