Description

Technical Field

[0001] The invention relates to the technical field of frequency converter heat dissipation, in particular to a heat dissipation mechanism of a frequency converter. Background Art

[0002] The frequency converter is an electric power control device that applies frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's working power supply. The frequency converter is mainly composed of rectification (AC to DC), filtering, inversion (DC to AC), braking unit, drive unit, detection unit, microprocessor unit, etc. The frequency converter adjusts the output power voltage and frequency by the opening and closing of the internal IGBT, and provides the required power supply voltage according to the actual needs of the motor, thereby achieving the purpose of energy saving and speed regulation. In addition, the frequency converter also has many protection functions, such as over-current, over-voltage, overload protection, etc. With the continuous improvement of industrial automation, frequency converters have also been widely used.

[0003] Publication No. CN203377773U discloses a frequency converter heat dissipation structure, including an upper shell, a lower shell, a frequency converter circuit board, a radiator and a cooling fan, wherein vents are arranged on opposite sides of the upper shell and the lower shell, and the radiator includes a heat conducting plate and a plurality of heat sinks arranged on one side of the heat conducting plate; the frequency converter circuit board is installed on the lower shell through the radiator, and there is a gap between the two sides of the radiator and the two sides of the lower shell, and the frequency converter circuit board and the heat sink are respectively located in the upper shell and the lower shell; the heat sinks are arranged in parallel to form an air duct between two adjacent heat sinks, and the two ends of the air duct correspond to the two vents on the lower shell respectively; the cooling fan is installed at the vent on one side of the lower shell, and the cooling fan and the heat sink at least partially overlap. Although the heat dissipation structure is simple and has good heat dissipation effect, it can effectively ensure the stable operation of the inverter, improve the reliability of the inverter, and thus extend the service life of the inverter. However, the fan in the heat dissipation structure blows air from one side to dissipate heat, so that the heat dissipation effect of the modules near the fan is acceptable. However, the heat dissipation effect will gradually weaken in the direction away from the fan, and the heat dissipation effect is not obvious. Moreover, since the air outlet of the fan is in a rotating state for a long time, external dust will enter the interior of the inverter through the air outlet, thereby causing damage to the electrical components inside the inverter. Due to the importance of the inverter, it needs to be inspected and maintained regularly. The existing inverter is usually installed by bolts, and it is time-consuming and laborious to remove the bolts. Therefore, we propose a heat dissipation mechanism for the inverter.
