1. What is a finned tube coil
As a basic heat exchange equipment, the fin built-in heat exchange coil is composed of a base pipe and a plate-fin type that is welded on the base pipe by spiral welding. Especially designed finned tubes produced by coiling.
2. What are the types?
From the material, it is divided into copper-fin built-in heat exchange coil, aluminum-fin built-in heat exchange plate, stainless steel plate-fin heat exchange coil, and from the appearance design to single-sided spiral coil and double-layer spiral coil. Fin built-in coils play an important role in convection equipment.
3. What are the outstanding advantages of finned tube coils compared to finned straight tubes?
The structure is simple, the standardization level is high, and the heat transfer effect is good.
Compared with the straight tube with built-in fin, the plate-fin coil has a higher energy consumption under the condition of the same consumption of metal materials.
From the direct view, it belongs to the sub-enhancement of heat transfer, but in essence, the total heat transfer area is enlarged.
At the same time, the development of heat transfer index has been produced, and the goal of secondary heat transfer enhancement has been achieved.
Its characteristic is that it can effectively increase the heat transfer area and expand the heat transfer index, and it is relatively easy to manufacture and ensure the stability of the operation.
