Frequency converter with internal environment automatic adjusting function and working method thereof

Abstract

The invention discloses a frequency converter with an internal environment automatic adjusting function and a working method thereof. The frequency converter comprises a cabinet body, and the cabinetbody is divided into an upper layer and a lower layer, wherein each layer is provided with a door; the upper cabinet body comprises a compressor, a first expansion valve, a humidifier, a radiator, a liquid storage tank, a second expansion valve, a drainage pipe, a third expansion valve, a display screen, a control button and an input and output terminal; the lower cabinet body comprises a filtering evaporator, a drainage pipe, a first throttling valve, a first heat absorption pipe, a frequency converter body, a second throttling valve, a second heat absorption pipe, a controller body, a thirdexpansion valve, a temperature sensor, a humidity sensor, a box body, a heat preservation layer and universal wheels. According to the frequency converter, the expansion valves are accurately adjustedthrough the controller body, a refrigerant conducts heat in the drainage pipe in order, so that the frequency converter body and the controller body can keep the temperature in a proper range, the heat conducted out by the refrigerant is used for providing heating energy for the humidifier, and the energy utilization rate is increased.

Description

technical field [0001] The invention relates to the field of frequency converters, in particular to a frequency converter with an internal environment automatic adjustment function and a working method thereof. Background technique [0002] The rapid development of modern power technology and computer control technology has promoted the technological revolution of electric transmission. In the field of modern industry, frequency converter is one of the important electrical appliances widely used. It is a key component of energy-saving control link and plays a role in power conversion and amplification Function, long-term operation will lead to increased heat, if not dissipated in time, it will affect the performance of each device, therefore, it is necessary to set up an environmental control device to maintain a stable working environment for the inverter. [0003] Existing frequency converters usually adopt air-cooling or liquid-cooling methods for temperature control. Air...

AI Technical Summary

Problems solved by technology

[0003] Existing frequency converters usually adopt air-cooling or liquid-cooling methods for temperature control. Air-cooling heat dissipation will bring a lot of dust, and the heat dissipation efficiency often depends on the heat dissipation area of ​​the heat sink itself. In the frequency converter, the heat dissipation of the heat sink The area is limited, and the volume of the heat sink is relatively large, which will occupy the design space of other devices and cause inconvenience in installation and maintenance. For water-cooled heat dissipation, the temperature of electronic components is often too high due to the excessive heat dissipation power of the refrigerant. Low, condensation and other phenomena will eventually lead to the failure of the whole machine, and the utilization efficiency of heat is relatively low during use, which consumes more energy, and it is impossible to comprehensively adjust the internal environment of the inverter
