Frequency converter integrated with air conditioning cooling

Abstract

The invention discloses a frequency converter integrated with air conditioning cooling. The frequency converter comprises a frequency converter body, an air conditioner body and a cabinet body. The cabinet body is internally provided with a first cavity for accommodating the frequency converter body and a second cavity for accommodating the air conditioner body, an air inlet and an air outlet aredisposed between the first cavity and the second cavity, the second cavity is internally provided with a fan assembly which is used for discharging air which enters into the second cavity from the first cavity via the air inlet and is cooled by the air conditioner body to the first cavity via the air outlet. The frequency converter integrated with air conditioning cooling has the advantages of simple structure, reasonable layout, self cooling and high cooling efficiency.

Description

technical field [0001] The invention mainly relates to the technical field of frequency conversion, in particular to a frequency converter integrated with air conditioning cooling. Background technique [0002] During the use of the frequency converter, its own inverter module, rectifier module and reactor and other key components will generate a lot of heat. At present, it is usually cooled by air cooling, water cooling or direct introduction of refrigerant from the main unit. [0003] Due to the large demand for cooling load and large air volume required by air-cooling technology, it is easy to cause the volume of the fan and the entire frequency converter to be too large, resulting in high noise of the whole machine; while water-cooling technology will cause circuit short circuit due to water leakage, resulting in electronic components The damage of the device; and the cooling method of directly passing the refrigerant into the heat-generating parts of the inverter from t...

[0003] Due to the large demand for cooling load and large air volume required by air-cooling technology, it is easy to cause the volume of the fan and the entire frequency converter to be too large, resulting in high noise of the whole machine; while water-cooling technology will cause circuit short circuit due to water leakage, resulting in electronic components The damage of the device; and the cooling method of directly passing the refrigerant into the heat-generating parts of the inverter from the main unit, because the refrigerant passed into the inverter is part of the main unit, the heat dissipation of the inverter under low-pressure differential and low-temperature conditions The stability becomes worse, and the inverter cannot be used independently from the main unit like the water-cooled inverter and the air-cooled inverter, which greatly limits the scope of use of the inverter
