小型离心风扇通过蜗壳导流实现较高风压，可克服一定风道阻力，适合短距离集中送风。
Small centrifugal fans achieve high static pressure through volute guidance, overcoming certain duct resistance and suitable for short-distance concentrated air supply.
体积紧凑，可嵌入车载设备、手持吸尘器等移动设备，在有限空间内提供稳定风压输出，广泛应用于汽车空调、医疗设备、小型加湿器等场景，兼顾风压与便携性。
Compact in size, they can be embedded in mobile devices such as vehicle equipment and handheld vacuums, providing stable static pressure output in limited spaces. Widely used in car air conditioners, medical equipment, small humidifiers, etc., balancing static pressure and portability.
