Frequency converter shell convenient for heat dissipation of frequency converter

Abstract

The invention relates to the technical field of frequency converters, and particularly relates to a frequency converter shell convenient for heat dissipation of a frequency converter. The frequency converter shell comprises a shell covering the outer side of the frequency converter body. At least one side surface of the interior of the shell is provided with a liquid storage chamber laying and extending along the surface. A cavity is arranged inside the liquid storage chamber. The liquid storage chamber is provided with a pipeline which is integrated with the liquid storage chamber and extendsout of the shell. The liquid storage chamber is partially filled with a heat absorbing medium capable of absorbing heat and gasifying within the set temperature. A sealed liquefaction chamber is connected directly above the shell through a fixed column integrated with the shell. A cooling device for cooling gas after heat adsorbing and gasifying of the liquid of the heat absorbing medium in the liquid storage chamber is connected with the liquefaction chamber. The liquefaction chamber is sealed and communicated with the pipeline through the connecting pipe having the integral structure with the liquefaction chamber so that the problems of poor heat dissipation effect and dust liquefaction chamber caused by using the heat dissipation holes for heat dissipation of the frequency converter inthe prior art can be solved. The frequency converter shell has good prospect in the technical field of the frequency converter.

Description

technical field [0001] The invention belongs to the technical field of frequency converters, and in particular relates to a frequency converter casing which facilitates heat dissipation of the frequency converter. Background technique [0002] Inverter is applied to more and more places, because the core circuit module of the inverter body has the characteristics of high integration, high frequency, high voltage, high speed, etc., the loss of power devices in the main circuit will generate heat, resulting in serious heat generation during operation , affecting the working effect of the inverter. Traditional inverters only have heat dissipation windows on their shells. When the inverter works for a long time and generates a lot of heat, it cannot dissipate heat in time, which will affect the service life of the inverter itself. The opening of the heat dissipation window will also allow the dust in the air to enter the inverter. Once it is adsorbed on the inverter body, it wi...
