Finned Tube Heat Exchanger Overview

Finned Tube Heat Exchanger Overview

Finned tube heat exchanger is a kind of heat transfer equipment used 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 and so on. The fins can also be made of steel strips, stainless steel strips, copper strips, aluminium strips and so on. Finned heat exchanger is mainly used for drying system air heating, is the main equipment in the hot air device, radiator using the hot medium can be steam or hot water, can also be used for thermal oil, steam working pressure is generally not more than 0.8Mpa, the temperature of the hot air in the 150 ℃ below.

Mainly by the air flow between the three rows of side-by-side spiral finned tube bundles, SRZ-type heat dissipation finned tube bundles of the processing process is anti-0.5 * 10 mm steel strip with mechanical winding method, wound in 18 mm seamless steel tube, and then hot-dip galvanised, can also be made of stainless steel tube and stainless steel belt made of all stainless steel heat, SRL-type radiator is a finned radiator rolled with steel tubes and aluminium bands, the unit length of the SRL type heat sinks are finned heat sinks rolled with steel tubes and aluminium strips, with a larger heat dissipation area per unit length than SRZ type. SEMEM finned heat exchanger due to the use of mechanical winding, cooling fins and heat pipe contact surface is large and tight, heat transfer performance is good, stable, air through the resistance is small, steam or hot water flow through the steel tube, the heat through the tightly wound in the steel tube on the fins to pass through the fins of the air to achieve the role of heating and cooling air.
