In the specifications of finned tube radiator, the application of steel aluminum finned tube radiator is more. Compared with other types of finned tube radiators, the main advantages are 3 points: the structural design of the steel-aluminum finned tube radiator is rigorous, including strength and heat exchange effect, which can ensure the safe operation of the equipment and meet the functions of users under different working conditions.

In the specifications of finned tube radiator, the application of steel aluminum finned tube radiator is more. Compared with other types of finned tube radiators, the main advantages are the following 3 points;

1: The structural design of the steel-aluminum finned tube radiator is rigorous, including strength and heat exchange effect, which can ensure the safe operation of the equipment and meet the functions of users under different working conditions.

2: As the main heat exchange element of the steel aluminum radiator, the finned tube has a considerable expansion area, high processing accuracy, smooth surface, and is not easy to wear, corrosion and aging. For the surface condensate has a good exclusion function, and not easy to accumulate dust.

3: The heat transfer performance of aluminum fins is also better than that of steel fins, and the sheet distance is smaller, and the unit heat exchange area is also large, so the use of steel aluminum fin tube radiator is more economical.

Steel aluminum finned tube radiator is a very mature heat exchange equipment, in the cold and heat medium and air for the occasion has been widely used.

Focus on hot spots

Characteristics and application fields of high frequency welding finned tube radiator

The base tube and the fin are firmly welded, the contact thermal resistance is small, the sheet distance is uniform, the wrinkle is small, it is not easy to accumulate dust, and the heat exchange efficiency is greatly improved. It is widely used in the waste heat recovery of heating furnaces, boilers, kilns, hot air furnaces and drying towers. Compared with traditional wound-tube air coolers, the outstanding advantages of high-frequency welded finned tube radiators are large heat dissipation area and cooling capacity. High, low air resistance, and its performance remains basically unchanged with the increase of service life.

How to buy SRZ finned tube radiator

The base tube of the traditional SRZ finned tube radiator is generally Φ 21*2 stainless steel or carbon steel tube, the height of the strip steel used for winding the sheet is 15mm, and the sheet distance is 5-8mm. The thickness of the sheet is generally 0.23-0.38mm.

Advantages of spiral high frequency welding finned tube

As a commonly used heat exchange element, high frequency welding finned tube needs to work for a long time under high temperature flue gas environment. For example, finned tubes used in boiler heat exchangers are used in harsh environments, high temperature and pressure, and corrosive environments. High-frequency welded finned tubes should have high-performance indicators, mainly including: corrosion resistance, wear resistance, low contact thermal resistance, high stability and anti-fouling ability.

Advantages of finned tube radiators

The finned tube radiator is not easy to ash. The cause of dust accumulation is the Karman vortex gap. Ash deposition will affect the flow of steam in the pipeline, and then affect the heat transfer efficiency of steam. After hot-dip galvanizing, the gap of the heat pipe is reduced, and it is not easy to form a dust accumulation angle, which affects the heat transfer efficiency. The integral finned tube radiator has stable performance and long service life. The thermal test has stable heat transfer performance and is suitable for various drying chambers and large and medium heating systems. The heat transfer efficiency is high, the corrosion resistance of the entire hot-dip galvanized layer is improved, and the service life is extended.

How to choose the material of finned tube radiator

The choice of finned tube radiator material determines the life of the heat exchanger and the cost of the equipment. When we choose the material according to the working conditions, we can choose the radiator with high cost performance, thereby reducing the production cost of the enterprise.
