Abstract

An integrated frequency converter comprises a chassis and a frequency converter device arranged in the chassis, wherein, a mounting cavity is arranged in the chassis, each frequency converter device is mounted on the inner side wall of the mounting cavity, a heat dissipation component for cooling the frequency converter device is arranged on the chassis, and the heat dissipation cooling air of theheat dissipation component penetrates the mounting cavity. The integrated frequency converter has the advantages of small volume, good heat dissipation effect, high operation reliability and the like.

Description

technical field [0001] The invention relates to the technical field of frequency converters, in particular to an integrated frequency converter. Background technique [0002] Inverter is a power control device that uses frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's working power supply. It mainly provides the required power supply voltage according to the actual needs of the motor, thereby achieving energy saving and speed regulation. the goal of. [0003] The existing frequency converter case is usually divided into multiple cavities, and each frequency converter device is arranged in the corresponding cavity according to the functional requirements. The layout of the internal components of the chassis is complex, resulting in a large volume and high cost of the chassis, and the components of the inverters are installed in different chambers, making it difficult to replace and maintain componen...
