Industrial finned heat exchangers | Customized finned tube radiators for power plants | The more finned tubes, the better the effect?


Finned tube radiators are widely used in life and industry. Many laymen know the importance of finned tubes in radiators. So some people think that the more finned tubes, the better the effect. So is it true? the answer is negative. The finned tubes in the finned tube radiator are arranged according to a certain scientific design, more or less will affect its performance. Let us analyze the reason next.


First of all: in terms of process difficulty, if the finned tubes are arranged too densely, the process will increase considerable difficulty. The cost is something that many companies are unwilling to bear. Because this virtually increases the cost on the product. At present, the price of finned tube radiators is very transparent. With the continuous expansion of the market, the number of enterprises of the same type continues to increase. After the cost increases, market sales will inevitably cause great difficulties, which will affect the development of the enterprise.


Second: From the perspective of cleaning and maintenance, if the finned tubes are too densely arranged. As we all know, this is very easy to accumulate dust. The key is that it is difficult to clean the dust itself. If the density increases, it will be even more difficult to clean the dust. All aspects of maintenance cause difficulties, but also affect the service life of the finned tubes, causing unnecessary losses to the enterprise.


Finally: If the finned tubes increase, the heat transfer area increases. The heat transfer will increase, but it will be discounted. If the height is increased, the efficiency of the fins will be lower, and the economy of increasing the fins will decrease instead.

Finned tube radiators are currently the most widely used heat exchange equipment in industry. It is a cold and heat exchanger that adds fins to the heat exchange tube to increase the heat dissipation area. Among them, the steel-aluminum composite tube (radiator) is composed of a wound-type steel-aluminum composite finned tube and a rolled-sheet type steel-aluminum composite finned tube. It takes advantage of the pressure resistance of steel pipes and the efficient thermal conductivity of aluminum, and is compounded on a special machine tool. The advantages of steel-aluminum composite tube radiators are irreplaceable by other types of finned tube radiators.


The finned tube radiator is used for heating and cooling the air, its structure is compact, and the unit heat exchange area is large. At present, it has been widely used in textile, printing and dyeing, petroleum, chemical industry, drying, electric power and other fields.
