Description

A frequency converter with heat dissipation function Technical Field

[0001] This utility model relates to the field of frequency converter technology, specifically to a frequency converter with heat dissipation function. Background Technology

[0002] A frequency converter is a power control device that uses frequency conversion technology and microelectronics to control an AC motor by changing the frequency of the power supply. Frequency converters also provide the required power voltage according to the actual needs of the motor, thereby achieving energy saving and speed regulation.

[0003] This utility model, disclosed in Chinese Patent Publication No. CN219611591U, discloses a frequency converter with heat dissipation function, belonging to the field of frequency converter technology. It addresses the problems of existing frequency converters, which mostly rely solely on fans for heat dissipation, resulting in poor cooling performance. This leads to insufficient cooling of internal components and inadequate heat dissipation during operation. It also addresses the issue of existing frequency converters being bolted to equipment, making replacement inconvenient. The device includes a heat dissipation mechanism, an airflow mechanism, a dustproof mechanism, and a clamping mechanism. Activating a first motor drives the heat dissipation and airflow mechanisms, dissipating heat from the frequency converter. Simultaneously, with the assistance of a liquid cooling component, the airflow generated by the heat dissipation mechanism is converted into cool air, accelerating the heat dissipation effect. The combination of a first support plate, a sliding groove and slider, a second support plate, a threaded rod, and a clamping plate allows for the clamping and fixing of frequency converters of different specifications, while facilitating disassembly and replacement.

[0004] When implementing the above solution, the applicant discovered that the inverter with heat dissipation function cools down by cooperating with a fan and liquid cooling components. However, the fan and liquid cooling components are only located at the top of the inverter body, which leads to a higher temperature at the bottom of the inverter body, resulting in uneven heat dissipation. Based on this, the present invention designs an inverter with heat dissipation function to solve the above problems. Summary of the Invention

[0026] Please refer to Figures 1-4. A frequency converter with heat dissipation function includes: a working housing 1, with a top fan 2 and a bottom fan 3 respectively installed at the top and bottom of the inner cavity of the working housing 1; a rotation mechanism, located inside the working housing 1 and used to drive the rotation of the top fan 2, the rotation mechanism including a drive component and a passive component, the drive component being located inside the working housing 1 and used to drive the rotation of the passive component, the passive component being located outside the drive component and driving the rotation of the top fan 2; and a moving mechanism, located at the bottom of the rotation mechanism and used to move the position of the bottom fan 3.

[0027] The drive assembly includes a protective frame 4 mounted on one side of the working housing 1. A dual-axis motor 5 is installed inside the protective frame 4. A rotating rod 6 is mounted on one side of the output shaft of the dual-axis motor 5. A driving bevel gear 7 is mounted on the outer ring of the rotating rod 6. Multiple sets of driving bevel gears 7 are arranged horizontally. The passive assembly includes a support plate 8 installed inside the working housing 1. A passive rod 9 is rotatably connected inside the support plate 8. A driven bevel gear 10 is mounted on the outer ring of the passive rod 9. The driving bevel gears 7 and the driven bevel gears 10 mesh with each other. Multiple sets of driven bevel gears 10 are arranged horizontally. The top of the top fan 2 is connected to the bottom of the passive rod 9. Multiple sets of the passive rod 9 and the top fan 2 are arranged horizontally.

[0028] In this embodiment of the invention, when the temperature rises to a certain level, the top fan 2 and the bottom fan 3 start up to accelerate the air circulation inside the working box 1. The dual-axis motor 5 starts working and drives the active bevel gear 7 to rotate through the rotating rod 6. The active bevel gear 7 meshes with the driven bevel gear 10, thereby driving the passive rod 9 to rotate, which makes the top fan 2 rotate faster.

[0029] Please refer to Figures 1-4. The moving mechanism includes a first transmission roller 11 installed on the other side of the output shaft of the dual-axis motor 5, and a second transmission roller 12 installed on one side of the working housing 1. The first transmission roller 11 and the second transmission roller 12 are connected by a belt. A one-way lead screw 13 is installed on one side of the second transmission roller 12. A moving block 14 is threadedly connected to the outer ring of the one-way lead screw 13. The top of the moving block 14 is connected to the bottom of the bottom fan 3. A limit assembly is installed inside the working housing 1. The limit assembly includes two sets of limit rods 15 installed inside the working housing 1. The limit rods 15 are symmetrically distributed and are inserted inside the moving block 14.

[0030] A mounting plate 16 is installed between the top fan 2 and the bottom fan 3. The inverter body 17 is mounted on the top of the mounting plate 16. A temperature sensor 18 is installed inside the working housing 1. Ventilation holes 19 are provided at the top and bottom of the working housing 1. Heat dissipation holes 20 are provided on both sides of the working housing 1. Support blocks 21 are installed at the bottom of the working housing 1. Four sets of support blocks 21 are arranged in a rectangular array. A maintenance plate 22 is hinged to the front of the working housing 1.

[0031] In this embodiment of the utility model, the output shaft of the dual-axis motor 5 drives the unidirectional lead screw 13 to rotate through the first transmission roller 11 and the second transmission roller 12, so that the moving block 14 moves along the limit rod 15, thereby driving the position of the bottom fan 3 to move, so that the bottom fan 3 can better dissipate heat from the inverter body 17.

[0032] When using this inverter with heat dissipation function, first connect the external power supply, and the inverter body 17 on the mounting plate 16 starts working. The temperature sensor 18 inside the working chamber 1 monitors the heat generated by the inverter body 17 in real time. When the temperature rises to a certain level, the top fan 2 and the bottom fan 3 start, accelerating the air circulation inside the working chamber 1 and dissipating the generated heat. The dual-axis motor 5 starts working, driving the driving bevel gear 7 to rotate through the rotating rod 6. The driving bevel gear 7 meshes with the driven bevel gear 10, thereby driving the driven rod 9 to rotate, causing the top fan 2 to rotate faster and enhance the heat dissipation effect. At the same time, the output shaft of the dual-axis motor 5 drives the one-way lead screw 13 to rotate through the first transmission roller 11 and the second transmission roller 12, causing the moving block 14 to move along the limit rod 15, thereby moving the position of the bottom fan 3, so that the bottom fan 3 can better dissipate heat from the inverter body 17. The setting of ventilation holes 19 and heat dissipation holes 20 further improves the heat dissipation performance of the working chamber 1. The inspection panel 22 facilitates equipment maintenance, and the observation glass 23 allows for easy observation of the inside of the work box 1.
