Yuhong Group for Polysilicon Project

2026-04-15

In Polysilicon manufacturing, thermal management is critical for process stability and energy efficiency. The Bimetallic Extruded Fin Tube, featuring a 304L Stainless Steel Base Tube and Aluminum Fins, is the premium choice for Air-Cooled Heat Exchangers (ACHE) in these high-demand environments.

Superior Material Synergy: 304L SS and Aluminum
  • 304L Stainless Steel Base Tube:

    The low-carbon 304L SS offers exceptional resistance to intergranular corrosion from Trichlorosilane (TCS) and Hydrogen Chloride (HCl). It ensures zero contamination of metallic ions, maintaining the high purity required for electronic-grade polysilicon.

  • Extruded Aluminum Fins:

    Aluminum’s high thermal conductivity combined with an increased surface area ensures maximum heat transfer efficiency, reducing the overall footprint of the cooling system.

Why Choose Extruded Fin Technology?

Unlike traditional tension-wound fins, the Extruded Fin Tube is manufactured through a high-pressure cold-rolling process.

  • Zero Contact Thermal Resistance:

    The mechanical bond between the base tube and aluminum fin is permanent, ensuring consistent heat transfer throughout the equipment's lifespan.

  • Full Base Tube Protection:

    The aluminum sleeve completely covers the 304L base tube, shielding it from external atmospheric corrosion and oxidation.

  • High Mechanical Durability:

    These fins are rigid and resistant to high-pressure water cleaning, making them ideal for the harsh outdoor conditions of polysilicon plants in regions like Northwest China.
