Cooling Fan For Frequency Converter

Cooling fan for frequency converter

As a key component in various fields, the reliability of the quality of the cooling fan is very important, which will directly affect the service life of the supporting products and is closely related to the normal operation of our common machines. In the field of automation, fans also have a crucial impact on the performance and service life of products such as frequency converters due to their heat dissipation function. Choosing a professional and responsible fan supplier is even more crucial. For frequency converters that are indispensable for equipment control and speed regulation, natural heat dissipation is generally used for low-power frequency converters, and their usage environment should be well ventilated, free from easily adhering dust and floating objects. The application objects of this type of frequency converter are mostly household air conditioners, CNC machine tools, etc., with low power and relatively good usage environment. A large number of studies and practices have shown that the failure rate of frequency converters will increase with the increase of temperature, and the service life will decrease with the increase of temperature. If the ambient temperature increases by 10 ℃, the service life of frequency converters will be halved.

The heating of the frequency converter is generated by internal losses. The main circuit accounts for about 98% of the losses in various parts of the frequency converter, while the control circuit accounts for 2%. In order to ensure the normal and reliable operation of the frequency converter, it is necessary to heat the frequency converter. We usually use a fan for heat dissipation; The built-in fan of the frequency converter can take away the internal heat dissipation of the frequency converter box. A high-power frequency converter also needs to add a fan to the control cabinet, and the air duct of the control cabinet should be designed reasonably. All air intakes should be equipped with dust screens, and the exhaust should be smooth to avoid the formation of eddies in the cabinet and the accumulation of dust in fixed positions; Select the matching fan according to the ventilation volume specified in the inverter manual, and pay attention to shockproof issues when installing the fan.
