Dc cooling fan, cases belong to a small classification of radiator cooling fan, the advantage is that by the dc power supply, smaller, compared with other cooling fan high energy saving efficiency, and little vibration, low noise, long service life, so the application is very extensive in the middle of the life. Then the following [by possessing dc cooling fan manufacturer Chi automotive air conditioning 】 For everybody simple introduction of the function and operation principle of dc cooling fan. Operation principle of dc cooling fan, radiator dc cooling fan consists of motor stator and rotor of two parts, on the stator poles ( Winding type or permanent magnet) , the rotor winding, after electrify, also formed on the rotor magnetic field ( The magnetic poles) And an Angle between stator and rotor poles have, in the stator magnetic field ( N pole and S pole) Attract each other, is the motor rotation. Change the brush seat, can change the Angle of the rotor poles ( Assumptions in the stator pole to start edge Angle, the pole to the other side of the rotor, the rotor pole is pointing in the direction of the stator pole motor direction of rotation) Direction, so as to change the direction of rotation of the machine. Dc cooling fan application areas: 1. Household appliances, 【 Air conditioning, automotive, water dispensers, camera, routers, etc. ) 2. Medical instruments' High frequency electric knife, biochemical, immune, blood clotting, blood analysis instrument 】 。 3. The auto industry' Automotive air conditioning, engine, condenser 】 4. Stage lights' LED lamps and lanterns, shoot the light, bath bully, speakers, etc) 5. Electronic communications' Electrical box, cabinet, switches, frequency converter, ATM, etc. ) 6. Industrial environmental protection' Welding machine, environmental protection equipment, refrigeration equipment 】 Dc cooling fan performance standard parameters of air volume: how many cubic meters per minute to produce wind fan work, the unit for M3min or CFM wind pressure: when the fan work pressure, the unit for mmH2O noise: fan of voice at work, there are mainly the wind noise, electromagnetic noise, bearing noise. The unit for the dB - Life: A fan doesn't work, the speed is lower than 85% of the rated speed is considered due at the end of its life. Life generally refers to the average life of fan. The environment temperature; Refers to the location of the fan is working temperature, environment temperature on the life of the fan has a great influence. High temperature fan life expectancy, low temperature bearing grease is unable to work. Above is the function and operation principle of dc cooling fan, hope that through this article can help you, also because of the application of dc cooling fan field is very wide, so in the market demand is very big, when a large number of purchasing selection dc cooling fan brand merchants is a top priority, we wen ling chi automotive air conditioning co. , LTD is a professional research and development production of dc cooling fan, dc fan, brushless motor, axial flow turbine cooling fan cooling cooling fan brands. Radiator cooling fan industry leader, complete specifications, reasonable price, more than ten years of experience in Taiwan enterprise research and development, free proofing, directly or indirectly from free design cooling scheme. Considerate after-sales service, the sample quickly, if you have any requirements, welcome everybody to come to consult.
