Heat dissipation dc cooling fan and cooling today to tell you about differences between the cooling fan
Wenling city chi automotive air conditioning technology co. , LTD was founded in 2002 in wen ling, is a specialized research and development, production, sales, radiator cooling fan of high-tech enterprises. Produced dc cooling fans, ac cooling fan, blower, waterproof/dustproof cooling fan, EC conversion and the cooling fan, radiator dc cooling fan, car radiator cooling fan, mute radiator cooling fan, radiator cooling fan, turbo cooling fan, dc dc cooling fan, centrifugal fan, blower, air blower factory, new energy dc cooling fan, brushless motor, etc. , has been widely used in: communications equipment, UPS power supply, medical equipment, electric welding machine, industrial control equipment, household electrical appliances, air purification industry, automobile industry, projectors, beauty equipment, sports equipment, and other areas of the industry. About heat dissipation dc cooling fan and cooling differences between the cooling fan. Dc cooling of the cooling fan speed signal output from three pin plug, commonly three fuses in the yellow and black + 12 v power supply and grounding, respectively, of a different color line is the rotational speed signal output line. It should be noted that some three cooling dc cooling fan, the third root lead lead is not speed signal output line, but the speed control signal, through it to the dc cooling fan motor speed regulation control signal. So far, the mode of the cooling fan's own monitoring alarm sensor and speed sensor of two types, using alarm sensor can be in when the cooling fan speed falls below a certain threshold values give alarm signal, and the speed signal output, which can realize real-time monitoring of the cooling fan speed. Cooling dc cooling fan operation is based on the principle of the ampere right-hand rule, the electric current through a conductor, can produce a magnetic field around, if put the conductor at a fixed magnetic field, it will generate attraction or repulsion, caused by moving objects. In the inside of the blades to heat dc cooling fan, attached to a charge in advance of the magnetic rubber magnet. Around the silicon steel sheet, the axis part two sets of coil winding, and use hall sensor component as synchronous detection device, a group control circuit, the circuit make the job of two groups of coil turns of coil axis. Simple point, heat dissipation dc cooling fan is by dc voltage and electromagnetic induction, the electrical energy into mechanical thereby giving impetus to the rotation of the cooling fan blades to achieve the purpose of heat dissipation. Heat dissipation dc cooling fan is the use of dc power to run, the dc power supply voltage must be consistent with the working voltage of electric fan on. If a battery is a DC power supply, use it to drive DC cooling fan, in addition to the charge of also look at the battery voltage and the working voltage of the cooling fan is consistent, if inconsistent with the voltage into a DC/DC converter.
