COIL-WOUND HEAT EXCHANGER

A coil-wound heat exchanger (CWHE) consists of one or more spirally wound tubes (coils) bundled together inside a shell. 

​

One fluid flows through the tubes (coiled around a central core), while another flows over the tubes in the shell.

Heat is transferred between the fluids through the tube walls.

The spiral design increases turbulence, enhancing heat transfer efficiency.

Key Features of Coil-Wound Heat Exchangers:


  • Compact Design – The coiled tube arrangement maximizes heat transfer surface area in a relatively small volume.

  • High Efficiency – The spiral winding enhances turbulence, improving heat transfer coefficients.

  • High-Pressure & Cryogenic Capability – Commonly used in LNG and industrial gas processing due to their ability to handle extreme temperatures and pressures.

  • Multi-Stream Operation – Can accommodate multiple fluid streams (e.g., natural gas, mixed refrigerants) in a single unit.

  • Robust Construction – Typically made from materials like stainless steel, aluminum, or nickel alloys for durability.
