Stainless Steel Tube Heat Exchanger for 500KW Dry Cooler

Stainless Steel Tube Heat Exchanger for 500KW Dry Cooler

The coils used in dry coolers usually have the following characteristics and requirements:

Material selection: commonly used materials include copper, aluminium and stainless steel. Copper has good thermal conductivity, but the cost is relatively high; aluminium is more economical, lightweight and has better thermal conductivity; stainless steel has excellent corrosion resistance.

Pipe diameter and wall thickness: the choice of pipe diameter and wall thickness depends on the working pressure, flow rate and heat transfer requirements. Smaller tube diameter can increase the heat transfer area per unit volume, but will increase the flow resistance; thicker wall can withstand higher pressure.

Surface treatment: In order to enhance the heat transfer effect, the surface of the coil may undergo special treatment, such as adding fins, coating treatment to improve the radiation heat transfer.

Manufacturing process: Good manufacturing process can ensure the sealing and reliability of the coil and reduce the risk of leakage.

Corrosion resistance: Since the dry cooler may be operated in different environments, the coil needs to have certain corrosion resistance to prolong the service life.
