The advantages of heat dissipation dc cooling fan, and performance

Today the continuous development of the electronics industry, many electronic products are more and more widely used, the demand is also increasing. Such as heat dissipation dc cooling fan, radiator dc cooling fan exactly what are the advantages to merchants favor and sought after? Wen ling chi car air conditioning technicians, here to introduce the advantage and function of heat dissipation dc cooling fan, radiator dc cooling fan advantages: 1, low cost of inverter, the inverter capacity low continue to run when the current inverter, rating is rectangular wave peak, induction motor need to sine wave current, direct current motor need rectangular wave current. Inverter to continue running when the current rating of generally refers to the effective value of the sine wave. To adhere to the inverter's ability to control the motor current and dc voltage inverter and motor should be enough difference between induced electromotive force. In this case, if the assumption of dc motor and induction motor current peak is equal, is 33% higher than that of the former power output than the latter, that is to say, the same rectifier/inverter to drive more than 33% higher than that of induction motor output power brushless dc motor. 2, high power factor is far higher than that of induction motor, the power factor because of the dc motor excitation magnetic field does not need power grid reactive current. Dc motor can be run on 1 power factor, it is highly advantageous to small power motor. Motor and induction motor has higher efficiency when compared with not only the rated load and power factor, and has more advantages in light load. 3, low loss, high efficiency, eliminate the loss of induction motor excitation current, permanent magnet dc motor work in synchronous operation mode at the same time, because of the permanent magnet excitation. To eliminate the switch frequency of the induction motor rotor core loss. These two aspects makes the running efficiency of permanent magnet dc motor is far higher than that of induction motor, small capacity motor efficiency is more obvious. 4, control performance is good, simple control dc fan speed regulation control is not only simple, compared with induction motor variable frequency speed regulation, and has better performance of speed adjustment. These advantages and characteristics of the heat dissipation dc cooling fan can be very good to use in its electronics industry, machinery and equipment. Because of its small convenient wait for a reason and also make its application more widely. The above is the advantage and function of heat dissipation dc cooling fan, more related knowledge, can ask our technical personnel.
