Fin heat exchanger is the most widely used type of heat transfer equipment in gas and liquid heat exchangers. It achieves the purpose of enhanced heat transfer by adding fins to the common base tube. The base tube can be made of steel tube; stainless steel tube; copper tube, etc. The fins can also be made of steel strip; stainless steel strip, copper strip, aluminum strip, etc.

Fin heat exchanger is mainly used for air heating in the drying system, is the main equipment in the hot air device, the heat medium used in the radiator can be steam or hot water, but also available thermal oil, the working pressure of steam is generally not more than 0.8Mpa, the temperature of the hot air is below 150℃.

Fin heat exchanger features.

(1)High heat transfer efficiency, due to the disturbance of the fins on the fluid so that the boundary layer is constantly broken, and thus has a large heat transfer coefficient; at the same time, due to the spacer, fins are very thin, with high thermal conductivity, so that the fin heat exchanger can achieve high efficiency.

(2)Compact, because the fin heat exchanger has an extended secondary surface, making it possible to reach a specific surface area of 1000㎡/ m3.

(3)Lightweight, the reason is compact and mostly made of aluminum, now steel, copper, composite materials, etc. have also been mass produced.

(4)Adaptable, fin heat exchanger can be applied to: gas-gas, gas-liquid, liquid-liquid, heat transfer between various fluids and the phase change of the set state change of heat. Through the arrangement and combination of flow channels can adapt to: countercurrent, staggered flow, multi-stream, multi-stream and other different heat transfer working conditions. Through the combination of series, parallel and series-parallel connection between units can meet the heat transfer needs of large equipment. Industry can be stereotyped, mass production to reduce costs and expand interchangeability through building block combination.

(5)Strict manufacturing process requirements and complex process.

(6)Easy to block, not corrosion-resistant, cleaning and maintenance is very difficult, so it can only be used for heat transfer medium clean, non-corrosive, not easy to scale, not easy to deposit, not easy to block the occasion.
