Problems solved by technology
The cooling methods mainly include water cooling and air cooling. In order to better cool and ensure the cooling effect, the existing two methods are used at the same time. If the water cooling method is used, after the heat exchange inside the inverter cabinet, It is easy to generate scale in the pipeline, which needs to be disassembled and cleaned, which is very inconvenient

The invention relates to the technical field of frequency converters, specifically to a double-cooling frequency converter. The cooling effect can be effectively ensured; no water scale is generated in a cooling pipe; and later-stage maintenance is convenient. The double-cooling frequency converter comprises a frequency converter cabinet body, wherein the double-cooling frequency converter is characterized in that an air cooling device and a liquid cooling pipe are arranged in the frequency converter cabinet body; the liquid cooling pipe passes through a power device; an inlet of the liquid cooling pipe communicates with a refrigerating fluid outlet of an external heat exchanger; the outlet of the liquid cooling pipe communicates with a refrigerating fluid inlet of the external heat exchanger through a refrigerating fluid recovery device; a refrigerating fluid is subjected to heat exchange cooling through a coolant of the external heat exchanger; and the external heat exchanger and the refrigerating fluid recovery device are arranged outside the frequency converter cabinet body.
Description
technical field [0001] The invention relates to the technical field of frequency converters, in particular to a dual cooling frequency converter. Background technique [0002] The built-in frequency conversion cabinet of large air-conditioning units, with the continuous increase of airborne power, but the relatively small installation size, how to remove the heat generated in the cabinet due to the operation process to the outside of the cabinet, is now the production of many frequency conversion cabinets. Manufacturers face challenges. The cooling methods mainly include water cooling and air cooling. In order to better cool and ensure the cooling effect, the existing two methods are used at the same time. If the water cooling method is used, after the heat exchange inside the inverter cabinet, It is easy to generate scale in the pipeline, and it needs to be disassembled for cleaning, which is very inconvenient. Contents of the invention [0003] In order to solve the ab...
