Components that collect and distribute refrigerant flow within condenser coils

Product Specifications

Technical details and manufacturing context for Headers/Distributors

Definition
Headers and distributors are critical components in condenser coils that manage refrigerant flow by collecting refrigerant from multiple tubes and distributing it evenly across the coil's circuiting system, ensuring optimal heat transfer efficiency and pressure balance throughout the heat exchange process.
Working Principle
Headers receive refrigerant from the compressor and distribute it to multiple parallel tubes in the condenser coil. Distributors ensure even flow distribution to prevent uneven cooling and maintain system efficiency. They work by creating pressure differentials that force refrigerant through multiple pathways while maintaining balanced flow rates.
Common Materials
Copper, Aluminum, Brass
Technical Parameters
  • Diameter and length specifications for header tubes and distributor connections (mm) Customizable
Components / BOM
  • Main Header Tube
    Primary collection and distribution channel for refrigerant
    Material: Copper or Aluminum
  • Distribution Outlets
    Branch connections to individual coil circuits
    Material: Brass or Copper
  • Connection Fittings
    Secure connections between header and coil tubes
    Material: Brass or Steel
  • Pressure Equalization Ports
    Maintain balanced pressure across distribution system
    Material: Copper or Brass
Engineering Reasoning
0.5-3.5 MPa (5-35 bar)
4.2 MPa (42 bar) internal pressure causing permanent deformation of distributor channels
Design Rationale: Plastic deformation due to yield strength exceedance of aluminum alloy 6061-T6 (276 MPa yield strength) under refrigerant pressure loading
Risk Mitigation (FMEA)
Trigger Refrigerant flow maldistribution exceeding 15% deviation from design distribution
Mode: Localized frost formation on downstream evaporator sections
Strategy: Integrate flow sensors with PID-controlled metering valves at each distributor outlet
Trigger Corrosion-induced pitting reaching 0.8 mm depth in distributor internal surfaces
Mode: Refrigerant leakage at 0.05 kg/s exceeding ASHRAE Standard 15 limits
Strategy: Apply 50 μm thick PTFE coating on all internal surfaces exposed to R-410A refrigerant
