【摘要】 针对高速电吹风的噪声和换热技术问题，对KF-K9系列11万转超高转速电吹风的风道结构进行了设计。通过将电吹风风道的进风口设置成圆弧状扩口结构，采用高速导风通道换热设计，增加倒转自动清洁功能，有效实现了降噪和高效换热。测试结果表明：KF-K9系列11万转超高转速电吹风最高风速可达24 m/s,噪声控制在82.5 dB以下，出风温度最高达到117℃,具有较好的性能指标。更多还原

【Abstract】 Aiming at the noise and heat transfer technical problems of high-speed hair dryer, the air duct structure of KF-K9 series 110 000 rpm ultra-high speed hair dryer is designed. By setting the air inlet of the electric air duct into an arc-shaped expansion structure, this design adopts the heat transfer design of the high-speed air guide channel, increases the reverse automatic cleaning function, and effectively realizes the noise reduction and efficient heat transfer. The test results show that the maximum wind speed of KF-K9 series 110 000 rpm ultra-high speed hair dryer can reach 24 m/s, the noise is controlled below 82.5 dB, and the highest outlet temperature is 117 ℃, which has a good performance index.更多还原
