DC Fans and W2G115-AD17-13: Application Field and Working Principle

DC fans, also known as direct current fans, are powered by a direct current (DC) power source, such as batteries, solar cells, and fuel cells. Operating as blowers or exhaust fans, they are used to provide ventilation, reduce the temperature inside an enclosed area, and suck foreign particles or liquids out of the environment. DC fans are found in a variety of applications, including HVAC units, computers and audio/video equipment, refrigerators, and other household appliances, as well as robotics, aircraft, automotive and other industrial applications. The W2G115-AD17-13 is an axial-flow DC fan designed for industrial applications that require a high-strength, high-performance fan with a wide operating range. The fan features a double bearing system for increased life, low fan noise, and improved airflow characteristics. It is constructed with high-quality die-cast aluminum, and is designed to operate at temperatures between -40 degrees Celsius and +65 degrees Celsius. The W2G115-AD17-13 has a maximum airflow capacity of 75.7 CFM, at a static pressure of 1.38 inch-H2O, which makes it ideal for applications that require a high level of air movement without creating excessive noise.The working principle of the DC fan is based on the law of conservation of energy, which states that energy in a closed system must remain constant. When power is supplied to the fan, the voltage causes electrons in the DC motor to move from one coil to another, generating a magnetic field that causes the fan blades to rotate. This rotation reduces the pressure inside the fan, creating an area of low pressure. As the air inside the fan is drawn in by the lower pressure, it is forced outward into the higher pressure area, creating airflow. The speed of the DC fan is regulated using PWM (Pulse Width Modulation). When a PWM signal is applied to the fan, the duty cycle, or proportion of time that power is applied, is adjusted. As the duty cycle increases, the fan speed increases, and as it decreases the fan speed decreases. This allows for precise control of the fan speed, which can be used to help optimize performance, noise, and fan life.Overall, the W2G115-AD17-13 is an excellent choice for industrial applications that require high levels of air movement without generating excessive noise. It is constructed with high-quality materials and designed to operate in a wide range of temperatures, making it suitable for a variety of applications. Its use of a PWM signal for speed regulation allows for precise control, while its double bearing system helps ensure long life and enhanced airflow characteristics.
