Abstract

The invention relates to the technical field of frequency converters, in particular to a frequency converter for realizing heat exchange. The frequency converter comprises a main shell, a base and a connecting frame positioned between the main shell and the base, wherein an electronic component is arranged between the connecting frame and the main shell; a radiator is arranged in the base, and a fan and a grating plate are arranged on the two sides of the radiator respectively; and the main shell is provided with a through hole used for up-down air circulation, the main shell is provided with a heat conduction plate, and the heat conduction plate covers the through hole. The main shell is provided with the through hole for vertical air circulation, and the heat conducting plate covers the through hole, so that heat exchange is realized.

Description

technical field [0001] The invention relates to the technical field of frequency converters, in particular to a frequency converter for realizing heat exchange. 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. Moreover, the internal space of the frequency converter is divided into two-layer cavities or three-layer cavities. One of the chambers is equipped with a radiator and a fan, mainly for cooling the capacitors of the circuit board and the back of the circuit board. Some electronic components are in another chamber, and this chamber is usually airtight. At the same time, the inventors have found through research that during the use of the frequency converter, some heat needs to be dissipated on the front of the circuit board, and the existing airtight chamber is difficult to achiev...
