Finned radiators are the most widely used heat exchange equipment in gas and liquid heat exchangers. It achieves the purpose of enhancing heat transfer by adding fins to the ordinary base tube. The base pipe can be steel pipe; stainless steel pipe; copper pipe and so on. The fins can also use steel belt; stainless steel belt, copper belt, aluminum belt and so on.

The fin heat exchanger is mainly used for air heating in the drying system. It is the main equipment in the hot air device. The heat medium used in the radiator can be steam or hot water, or heat transfer oil. The working pressure of steam is generally not more than 0.8Mpa , The temperature of the hot air is below 170°C.
