Abstract

The invention discloses a frequency converter. At least four cavities are formed in a chassis; the first cavity is provided with an AC wire incoming unit; the second cavity is provided with a DC wireincoming unit; the third cavity is provided with an AC filter unit; the fourth cavity is provided with a converter unit; the first side plate of the third cavity is provided with a first fan; a vent hole is formed in the second side plate; the first fan is used for extracting hot air in the third cavity; the back side of the fourth cavity is provided with a refrigerant heat transfer system; and the refrigerant heat transfer system is used for conducting heat in the fourth cavity outside the fourth cavity. According to the frequency converter provided in the invention, through optimizing the internal layout and the installation of the frequency converter, reliable heat radiation of the frequency converter can thus be ensured, and thus the frequency converter has a simple structure and is easy to manufacture and install.

Description

technical field [0001] The present invention relates to the technical field of frequency converters, in particular to a frequency converter. Background technique [0002] The main circuit of the inverter is AC-DC-AC. The inverter unit in the main circuit will invert the received DC power into three-phase AC power with adjustable frequency and voltage, so as to supply power to the AC variable frequency motor to meet the needs of the motor. Require. Due to the unreasonable installation layout of the existing high-power inverters such as converter modules and reactors, it is easy to cause the problem of poor heat dissipation in the whole cabinet, which will seriously affect the life of the devices and reduce the reliability. Contents of the invention [0003] In order to solve the above problems, the present invention provides a frequency converter, the chassis of the frequency converter is formed with at least four cavities, the first cavity is provided with an AC incoming ...
