Description

Technical Field

[0001] This utility model relates to the field of frequency converter installation technology, and specifically to a frequency converter installation device. Background Technology

[0002] Vector inverter technology is based on the DQ-axis theory. Its basic idea is to decompose the motor current into D-axis current and Q-axis current, where the D-axis current is the excitation current and the Q-axis current is the torque current. This allows for separate control of the excitation current and torque current of the AC motor, giving the AC motor control characteristics similar to those of a DC motor. It is an ideal control theory for AC motors, significantly improving their control characteristics. However, this control theory is no longer only applied to AC asynchronous motors; it is also widely used in DC variable frequency motors (BLDC, i.e., permanent magnet synchronous motors).

[0003] However, existing frequency converters are generally fixed using bolts and screw holes. While this method provides a secure hold, it is cumbersome and time-consuming when the converter needs to be disassembled and repaired. Furthermore, existing frequency converters have poor heat dissipation, resulting in low heat dissipation efficiency. This can easily damage the internal wiring, significantly impacting the operation of the vector frequency converter's circuitry and reducing its overall efficiency. Summary of the Invention

[0004] To address the existing technical problems, this utility model provides a frequency converter installation device, including a frequency converter body. The frequency converter body includes a cuboid shell, with elongated heat dissipation cavities on both the left and right sides of the shell, and a plurality of heat dissipation holes communicating with the interior of the shell on both the upper and lower sides of the shell. Each heat dissipation cavity is equipped with a phase change material that facilitates heat dissipation; Four support columns are fixedly installed at the bottom of the inverter body. A connecting plate is fixedly connected to the lower surface of the support columns. The connecting plate has a limit groove. A limit frame is placed in the limit groove. The lower end of the limit frame is connected to a base plate. A limit block is fixedly installed on the upper surface of the base plate. The limit block has a storage groove. A first spring is fixedly installed in the storage groove. A locking block is fixedly connected to the end of the first spring away from the storage groove.

[0005] A further embodiment is that the two heat dissipation cavities are respectively arranged vertically along the left and right sides of the housing, and the plurality of heat dissipation holes are arranged horizontally along the upper and lower sides of the housing.

[0006] A further option is that each of the two heat dissipation cavities is provided with a cover on the side away from the housing to seal the heat dissipation cavity.

[0007] A further embodiment is that the limiting frame has a through groove, and the limiting block is located in the through groove.

[0008] A further embodiment is that a support plate is fixedly installed on the upper surface of the base plate, a sliding rod is slidably connected to the support plate, a pressing plate is fixedly connected to one end of the sliding rod, and a push plate is fixedly connected to the other end of the sliding rod.

[0009] A further embodiment is that a second spring is coaxially mounted on the sliding rod, and the second spring is located between the support plate and the pressing plate.

[0010] A further option is that a shielding frame is fixedly installed on the upper surface of the base plate, and the shielding frame has a "U" shaped plate structure.

[0011] The beneficial effects of this utility model are:

[0012] This invention improves the heat dissipation performance of the inverter body by opening a heat dissipation cavity and several heat dissipation holes on the housing of the inverter body, and by cooperating the heat dissipation cavity and several heat dissipation holes.

[0013] This invention uses a first spring to eject the locking block from the storage slot, and the locking block then locks the limiting bracket and the limiting block together, thus securing the frequency converter. Additionally, pushing the pressing plate causes a pusher plate to push the locking block into the storage slot, allowing for the disassembly of the frequency converter. This enables rapid installation, securing, and disassembly of the frequency converter. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] like Figure 1-5 As shown, one embodiment of this utility model discloses a frequency converter installation device, including a frequency converter body 1. The frequency converter body 1 includes a cuboid shell. The left and right sides of the shell are provided with elongated heat dissipation cavities 20, and the upper and lower sides of the shell are provided with a plurality of heat dissipation holes 21 that communicate with the interior of the shell. The heat dissipation cavities 20 are provided with phase change materials that facilitate heat dissipation. Two heat dissipation cavities 20 are respectively arranged vertically along the left and right sides of the shell, and several heat dissipation holes 21 are arranged horizontally along the upper and lower sides of the shell.

[0017] It should be noted that the phase change material used in this embodiment has a high heat storage density; and the phase change material is composed of organic and inorganic materials, with a phase change temperature of 40℃-70℃. The organic material can be saturated fatty acids or straight-chain alkanes, and the inorganic material can be expanded graphite. By placing a material with high heat storage density in the heat dissipation cavity for efficient heat conduction, the heat transfer performance of the heat dissipation cavity is significantly improved. The phase change material in the heat dissipation cavity has the advantages of uniform heat dissipation and good thermal conductivity.

[0018] When the internal temperature of the housing rises rapidly, the heat is transferred to the housing and then to the heat dissipation cavity. When the temperature exceeds 40℃-70℃, the phase change material absorbs heat, undergoes a solid-liquid phase change, and stores the heat, thereby achieving heat dissipation and cooling of the inverter body and preventing the internal temperature of the inverter body from continuing to rise. The phase change material in the heat dissipation cavity is made of existing materials and is not limited in this embodiment.

[0019] This embodiment improves the heat dissipation performance of the inverter body by opening a heat dissipation cavity and several heat dissipation holes on the housing of the inverter body and by cooperating the heat dissipation cavity and several heat dissipation holes.

[0020] Both heat dissipation chambers 20 are provided with a cover on the side away from the shell to seal the heat dissipation chamber 20.

[0021] This embodiment, through the above-described configuration, enables the two heat dissipation cavities to be sealed by two caps respectively, so that both heat dissipation cavities form a closed space, preventing the phase change material from overflowing to the outside of the shell when it undergoes a phase change.

[0022] Furthermore, in this embodiment, four support columns 30 are fixedly installed at the bottom of the inverter body 1. A connecting plate 31 is fixedly connected to the lower surface of the support columns 30. The connecting plate 31 has a limiting groove 32. A limiting frame 33 is placed in the limiting groove 32. The limiting frame 33 has a through groove 330. The lower end of the limiting frame 33 is connected to a base plate 34. A limiting block 35 is fixedly installed on the upper surface of the base plate 34. The limiting block 35 is located in the through groove 330. The limiting block 35 has a receiving groove 36. A first spring 37 is fixedly installed in the receiving groove 36. A locking block 38 is fixedly connected to the end of the first spring 37 away from the receiving groove 36.

[0023] This embodiment, through the above-described configuration, allows the limiting block to be inserted into the through slot, the first spring to eject the retaining block from the storage slot, and the retaining block to lock the limiting frame and the limiting block in place, thus completing the fixation. Pushing the pressing plate causes the push plate to push the retaining block back into the storage slot, completing the disassembly. This achieves quick installation, fixation, and disassembly of the frequency converter, and the installation, fixation, and disassembly operations are simple. In use, the base plate is fixedly connected to the position of the frequency converter to be fixed, and then the fixing and disassembly of the frequency converter are completed through the cooperation of the limiting block and the retaining block.

[0024] In this embodiment, a support plate 39 is fixedly installed on the upper surface of the base plate 34. A sliding rod 40 is slidably connected to the support plate 39. A pressing plate 41 is fixedly connected to one end of the sliding rod 40, and a push plate 42 is fixedly connected to the other end of the sliding rod 40.

[0025] This embodiment, through the above-described settings, enables the pusher plate to push the card into the storage slot by pushing the pressing plate, thus completing the disassembly operation.

[0026] In this embodiment, a second spring 43 is coaxially provided on the sliding rod 40, and the second spring 43 is located between the support plate 39 and the pressing plate 41.

[0027] This embodiment, through the above-described configuration, enables the second spring to reset the pressing plate, facilitating future use.

[0028] In this embodiment, a shielding frame 44 is fixedly installed on the upper surface of the base plate 34. The shielding frame 44 has a "U" shaped plate structure. The locking block 38, the support plate 39, the sliding rod 40, the pressing plate 41, the push plate 42, and the second spring 43 are located inside the shielding frame 44.

[0029] This embodiment achieves the goal of preventing the pressure plate from being contacted and pressed by setting a U-shaped shield.
