Dongguan Wanhang Electronics Technology Co, Ltd. is a professional motor cooling fan supplier. We provide DC Micro Fans, DC Micro Blowers, mini centrifugal fan and so on. Want to know more? Please contact us. WHEE is a certified DC Centrifugal Blower/DC centrifugal fan China manufacturer in China. The sizes of centrifugal blowers for sale and centrifugal flow fan range from 40-130mm. The rotor of the blower is checked for static and dynamic balance. The finished product runs smoothly and has minimal vibration. Compared with axial cooler, centrifugal ones create high-pressure and steady airflow. The DC centrifugal blower manual is converted into mechanical energy through direct current, which drives the wind wheel to rotate. The air inlet and outlet are in vertical wind direction, constantly compressing the air, making it produce a large amount of air for blowing. If you would like to know all different types of fans and blowers available for sale, please contact us for a free Centrifugal fan catalogue/centrifugal blower catalogue with price listed. If there is any question holding you off buying a centrifugal fan, we are here for you always.

Dongguan Wanhang Electronics Technology Co, Ltd. is a professional cooling fan manufacturer. We provide DC Micro Fans, axial fan propeller, dc axial compact fan, axial fan for ventilation, cooler axial, DC Micro Blowers, dc brushless cooling fan and so on. Want to know more? Please contact us. If you want to buy one, we will give you the axial fan static pressure and axial fans specifications. WHEE manufactures certified DC China axial fan . The range is from 40-120mm. The core materials for axial flow fan/clooer are all imported, waterproof and dustproof grade IP56, intelligent control design such as PWM and temperature control, etc. Configuration of industrial axial fans run quitely. For moving large volumes of air, axial cooling fun is ideal. Design of compact axial fans saves installation space. Compared with centrifugal funs and blowers, axial fans have higher operating speed, require a low power input for operation, and the airflows they create are of low pressure. Axial Fans Standards Temperature 25℃ and relative humidity 60% shall be the standard if no doubt arises in the judgment. However, it is permitted that tests are conducted in the environment of temperature 5~35℃, relative humidity 45 ~ 85%. Insulation resistance: At least 10 MΩ at 500VDC between the internal stator and both lead wires. Dielectric strength: Applied a 500VAC for 1.0 minute or 600VAC for 2 seconds between housing and both lead wires. In accordance with the Restriction of Hazardous Substances(ROHS)Directive, WHEE DC cooling fans have complied with law and discipline not to employ the forbidden substances, and restrict the allowable concentration of some limited substances deliberately in our components. Axial Fans FAQs How Long Is Your Axial Fans Wire Length? Wire length and the terminal can be customized according to your requirements, default wire length is 200mm. What Kind Of Function Can We Choose For Axial Fans? Auto-restart, Speed detection, Stoppage Alarm, Waterproof, PWM function, Temperature control. The commonly used functions are as follows: PWM speed regulation function: PWM is a kind of frequency conversion speed regulation, namely pulse width regulation. By adjusting the pulse width on the fundamental wave, the voltage and frequency of the sine waves can be adjusted, so as to adjust the speed of the motor. FG speed measurement function: Depending on the temperature change, the hall element generates pulses and then detects the pulse frequency to measure the speed. Every turn of the fan, the internal detection circuit will send 2 pulse signals from the speed measuring line (usually yellow) to the counting circuit on the motherboard. The speed measuring chip of the motherboard only needs to calculate how many pulse signals it receives per second or per minute to realize the speed measuring RD alarm function: RD signal, whose function is to output low level when the fan is running, and high level when the fan is not running. By detecting this signal, the CPU can know whether the fan is running normally. TC temperature control function: According to the CPU load and temperature adjust the speed, low load low temperature can reduce the speed, reduce noise, prolong the life of the fan, high load high temperature automatically increase the speed, conducive to heat dissipation. How Long is WHEE Axial Fans MTTF? The different bearing type has different MTTF. Two ball bearings can last up to 50,000hrs; F.D. The bearing can last up to 40,000hrs; Sleeve bearing can last up to 30,000hrs when operated at 40℃ and 45 ~ 85% relative humidity of the specified voltage rating.

Please contact us. WHEE has an independent research and development team that solves and optimizes cooling solutions from complete systems, so besides a variety of cooling fan for sale, we also offer quality cooling fan accessories . WHEE has accumulated experience in designing cooling fan accessories and modules over the years. The cooling modules are mainly made by hardware mold development, metal stamping, CNC processing, welding and assembly. Accessories FAQs What is a Thermal module? Thermal Module is designed for use in systems/devices/equipment. And other modules for heat dissipation. Now they refer to the heat dissipation devices of laptop computers and then to the heat dissipation devices of desktop computers and projectors using heat conduits. What are the mechanisms of the Thermal module? We adopt the Heat exchange concept of RHE(Remote Heat Exchanger) to solve the problem of the system waste Heat. Therefore, the Heat Exchanger of the all-in- one machine is basically composed of three parts, namely, Heat conduction section, Heat Exchanger section and elastic locking mechanism, plus some attached pieces. The heat pipe plays the role of rapid heat conduction in the heat conduction section, and the fan provides the airflow needed for forced convection in the heat dissipation section, which is the technical core of the heat conduction section and the heat dissipation section respectively. How about the performance of Thermal Module? Thermal Module is a kind of efficient heat dissipation device, which has unique heat dissipation characteristics. That is, it has high thermal conductivity, and the axial distribution of temperature between the evaporation section and the cooling section is uniform and basically equal. The heat resistance of the radiator is determined by the thermal conductivity of the material and the effective area within the volume. When the volume of solid aluminum or copper radiator reaches 0.006m, increasing its volume and area cannot significantly reduce the thermal resistance. For discrete semiconductor devices with two-sided heat dissipation, the heat resistance of air-cooled all-copper or all-aluminum radiators can only reach 0.04℃/W. The Thermal Module can reach 0.01℃/W. Under the condition of natural convection cooling, the performance of the heat pipe radiator can be improved more than ten times that of a solid radiator.
