Air coolers with external finned heating tubes utilize high-efficiency heat exchange coils and an optimized fin structure, significantly improving heat transfer efficiency on the air side. By wrapping metal fins around conventional electric heating tubes, the finned heating tubes significantly increase the heat dissipation area, increasing heat dissipation efficiency by 2-3.5 times compared to traditional bare tubes. This also reduces heat loss, improving heating speed and thermal efficiency. The heating tubes are made of high-quality stainless steel, offering excellent corrosion resistance and a long service life. These air coolers are suitable for a variety of industrial applications, such as air conditioning, ovens, and spray painting.
