DC Fans are essential parts of any electrical system, specifically when they are used in automotive applications to help cool and reduce noise levels. As technology advances, more efficient and versatile DC fan designs have been developed, such as the RER175-42/18/2TDMLP. This fan is specifically designed for higher voltage applications and combines both forced-air and pulse-width modulation (PWM) technology. Here we will discuss the application field and working principles of this fan.Application Fields: The RER175-42/18/2TDMLP is a high-power, high-reliability DC fan, specifically designed to be used in automotive applications to help reduce noise levels and increase cooling efficiency. It can also be used in the industrial field, such as in water-cooling applications. This fan is ideal for vehicles, including electric and select hybrid vehicles, that require a higher fan speed than the traditional 24V models. As such, the RER175-42/18/2TDMLP is well suited for vehicles such as SUVs, vans, and light trucks.Working Principle: The RER175-42/18/2TDMLP combines both forced-air and pulse-width modulation (PWM) technology. PWM technology is a form of AC/DC modulation that increases the fan’s ability to maintain a consistent speed by cycling power to the fan on a duty cycle. For example, in a 24-volt system, this fan can be operated at the rated speed by cycling power on for 6 milliseconds and then off for 6 milliseconds. This allows for an incredibly efficient and precise speed control over the fan’s operating range. This means that the fan can be easily and accurately controlled to maintain the desired temperature in any application.The forced-air technique takes advantage of an internal air-movement chamber to create a “cross-flow” of air that allows more air to be delivered faster and more efficiently. This helps to improve both the fan’s cooling effect and its energy efficiency. This fan can also be run in either push- or pull-type configurations, further increasing its versatility in different application scenarios.Conclusion: The RER175-42/18/2TDMLP DC fan has been designed with automotive applications in mind and can be used to effectively improve noise reduction and cooling efficiencies in these systems. It also has a wide range of possible applications, including industrial water cooling systems. Its combination of forced-air and PWM technology increases its efficiency and allows for more precise control over its speed range. The RER175-42/18/2TDMLP DC fan is an ideal choice for those looking for a reliable and efficient fan for their automotive and industrial applications.
