Abstract

The invention discloses a frequency converter. The frequency converter comprises a box body shell (1); a plurality of component modules which are modularly designed and detachably mounted are arrangedin a box body cavity of the box body shell (1); and the plurality of the component modules are arranged in sequence in the up-down direction in the box body cavity and are arranged in a layered modein the front-back direction. According to the frequency converter, the modular and layered structure design modes are adopted, so that the structure in the box body cavity can be more compact and ordered, meanwhile the frequency converter is convenient to mount and maintain, and the internal heat dissipation effect is better.

Description

technical field [0001] The present invention relates to the field of frequency converters, in particular to a frequency converter. Background technique [0002] Existing frequency converters have complex structures, large volumes, low assembly efficiency, and high cost of the complete machine. At the same time, since most frequency converters use air-cooled heat dissipation, the heat dissipation effect is poor and the noise is large. Contents of the invention [0003] The object of the present invention is to provide a frequency converter with compact structure, good heat dissipation effect and low cost. [0004] In order to achieve the above object, the present invention provides a frequency converter, which includes a box shell, and a plurality of detachable component modules with a modular design are built in the box cavity of the box shell. The device modules are arranged sequentially along the up-down direction in the box cavity and layered along the front-rear direc...
