Cooling fan as a key accessories, applied to a variety of fields, so the requirements of reliable quality, directly affect the service life of equipment, inverter cabinet cooling fan directly affect the performance of products, so what should be paid attention to when choosing? In the selection mainly consider the normal working temperature inside the cabinet, the highest ambient temperature outside the cabinet, find a temperature difference, fan ventilation rate, estimate the air capacity inside the cabinet. According to the protection level of the equipment, it is necessary to consider the function of dust-proof and moisture-proof. The general used equipment is mainly: Air Conditioner, Fan, heat exchanger, and the appropriate selection of different power equipment according to the size of the cabinet, according to the model of Dongxingyue as a reference can choose frequency converter fan 602524v high air volume, frequency converter fan 802524v high air volume, frequency converter fan 922524v high air volume, frequency converter fan 123824v high air volume, these models can be made of frequency converter cooling fan used. The above is Dongxingyue on the frequency converter Cabinet Cooling Fan selection of a simple introduction, a good frequency converter cooling fan is very important, not only to make the normal operation of the equipment, but also to extend its service life, work efficiency also increased, if you want to know more about the cooling fan knowledge can follow us.
