Production of Cooling Coils in Dry Coolers

Structure and Material

Basic Structure: Cooling coils are usually made of copper pipes or stainless - steel pipes, through which the fluid to be cooled, such as ethylene glycol solution or water, flows. The outer surface of the coil is often equipped with fins to increase the heat - dissipation area and improve the heat - exchange efficiency.

Common Materials: Copper has good thermal conductivity and is suitable for applications with high heat - exchange requirements; stainless - steel pipes have strong corrosion resistance and are suitable for harsh working environments, such as occasions with high humidity or corrosive gases.

Working Principle

When the hot fluid passes through the cooling coil, the heat is transferred from the fluid to the coil wall, and then from the wall to the fins and the surrounding air. At the same time, the fan forces the air to flow, so that the cold air continuously passes through the surface of the cooling coil to take away the heat, thus cooling the fluid.

Functions and Advantages

Core Function: Realize the heat exchange between the refrigerant and the air, and regulate the air temperature. It can cool the fluid to a lower temperature to meet the cooling needs of different processes.

Advantages in the Whole Machine: The use of cooling coils makes dry coolers save water and be environmentally friendly, as they do not require a large amount of cooling water. At the same time, it also has the advantages of stable operation, good cooling effect, and convenient installation.

Influence on the Performance of Dry Coolers

The design parameters of the cooling coil, such as the number of coil turns, tube diameter，and fin pitch, as well as the material and shape of the fins, will all have a significant impact on the heat - exchange efficiency and overall performance of the dry cooler. Optimizing these parameters can improve the cooling capacity and energy - saving effect of the dry cooler.
