Novel frequency converter

Abstract

The presenti nvention provides a novel frequency converter. An outer enclosure is convexly arranged on the bottom plate of the frequency converter body, the plurality of heat dissipation through holes are formed in the bottom plate, and the inner enclosure consistent with the outer enclosure in height is convexly arranged on the edges of the heat dissipation through holes, so that a plurality of heat dissipation cavities can be formed by combining the outer enclosure and the inner enclosure; and the peripheral baffle is provided with a plurality of exhaust holes communicated with the heat dissipation cavity, so that the surface of the heat dissipation device can be exposed in the air to the maximum extent, the self-heat dissipation area is increased, the heat dissipation speed is improved, heat backflow is effectively reduced, and dust in the external environment can be prevented from entering the frequency converter. Besides, a multi-surface radiating fin structure is adopted, a plurality of first radiating fins are arranged on the top plate of the radiator, and a plurality of second radiating fins are arranged on the side plates, so that the radiator can form a good chimney effect during self-radiating, the radiating efficiency is greatly improved, the sealing effect is excellent, the service life of the frequency converter is effectively prolonged, and the use cost of a user is reduced.

Description

technical field [0001] The invention relates to the technical field of frequency converters, in particular to a novel frequency converter. Background technique [0002] The frequency converter is a power control device that uses frequency conversion technology and microelectronics technology to control the AC motor by changing the frequency of the motor's working power supply. With the continuous improvement of industrial automation, frequency converters have also been widely used. [0003] When the frequency converter is working, it will generate a certain amount of heat, which will affect the normal operation of the frequency converter. In order to make the work of the frequency converter more stable, it is often necessary to cool down the frequency converter; and with the rapid development of high-power converter technology , the heat dissipation requirements of the inverter are getting higher and higher. [0004] In the inverter industry, due to dust in the environment...
