Component Specifications

Definition
Coil tubes are precision-engineered tubular components within evaporator systems that facilitate phase change heat transfer. They consist of serpentine or helical arrangements of metal tubing through which refrigerant flows, absorbing heat from the surrounding environment during evaporation. These tubes are engineered with specific geometries to maximize surface area contact and optimize thermal conductivity while maintaining structural integrity under varying pressure and temperature conditions.
Working Principle
Coil tubes operate on the principle of convective and conductive heat transfer. Refrigerant enters as a low-pressure liquid-vapor mixture, absorbing latent heat from the surrounding air or liquid medium as it evaporates within the tubes. The tube material's thermal conductivity, combined with optimized flow patterns and surface enhancements, maximizes heat absorption efficiency while maintaining proper refrigerant distribution throughout the evaporator system.
Materials
Typically copper (C12200, C10200) or aluminum alloys (3003, 6061) with internal grooving or enhanced surfaces. Copper offers superior thermal conductivity (385 W/m·K) and corrosion resistance, while aluminum provides lighter weight and cost advantages. Special applications may use stainless steel (304, 316) for corrosive environments.
Technical Parameters
  • Tube OD 3/8" to 5/8" (9.5mm to 15.9mm)
  • Surface Area 0.1-0.3 ft²/ft (0.03-0.09 m²/m)
  • Wall Thickness 0.016" to 0.035" (0.4mm to 0.9mm)
  • Temperature Range -40°F to 300°F (-40°C to 149°C)
  • Length per Circuit 10-50 ft (3-15 m)
  • Operating Pressure 150-500 psi (10-34 bar)
Standards
ISO 9303, ISO 9304, DIN 2391, ASTM B88

Frequently Asked Questions

What is the difference between copper and aluminum coil tubes?

Copper offers better thermal conductivity and corrosion resistance but is more expensive. Aluminum provides lighter weight and lower cost but requires larger surface areas for equivalent heat transfer. Material selection depends on application requirements, budget, and environmental conditions.

How often should coil tubes be inspected?

Industrial evaporator coil tubes should undergo visual inspection every 3-6 months and comprehensive testing annually. Frequency increases in corrosive environments or high-usage applications to prevent efficiency loss and catastrophic failures.

Can different coil tube materials be mixed in one system?

Generally not recommended due to galvanic corrosion risks. If mixing is unavoidable, proper isolation techniques and corrosion inhibitors must be implemented, following ASHRAE and manufacturer guidelines.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
