Inner Grooved Copper Tubes for Advanced Air-Conditioning & Refrigeration Systems

Inner Grooved Copper Tube – High Efficiency Copper Tube for Refrigeration Systems

The Inner Grooved Copper Tube is a high-performance copper tubing solution designed to enhance heat transfer efficiency in refrigeration and air-conditioning systems. By incorporating precision internal grooves along the tube’s inner surface, the tube increases the contact area between the refrigerant and the tube wall, improving thermal performance and system efficiency.

Manufactured using high-quality copper and engineered for modern HVAC and refrigeration applications, inner grooved copper tubes help improve cooling efficiency while supporting reliable heat exchange in evaporators and condensers.

Advanced Inner Groove Design

The inner grooved tube structure features specially designed micro-grooves along the inner surface of the tube. These grooves promote turbulence within the refrigerant flow, increasing the heat transfer coefficient and improving overall system performance.

The groove geometry includes several critical parameters such as outer diameter, groove depth, groove angle, helix angle, and number of teeth, which are precisely engineered to optimise heat transfer performance.

• Outer Diameter (D): Defines the external size of the copper tube
• Groove Depth (H): Determines the depth of the internal grooves
• Bottom Wall Thickness (TF): Thickness of the tube wall beneath the grooves
• Helix Angle: Controls the spiral orientation of the grooves
• Number of Teeth: Total number of internal groove profiles

High Thermal Performance

Inner grooved copper tubes significantly improve heat transfer efficiency compared to standard smooth copper tubes. The increased internal surface area and enhanced refrigerant turbulence allow refrigeration systems to operate with greater efficiency.

This improved heat transfer capability supports more efficient cooling, reduced energy consumption, and better overall system performance.

Applications

Inner grooved copper tubes are widely used in modern cooling and refrigeration systems where efficient heat exchange is critical.

• Air conditioning systems
• Refrigeration equipment
• Evaporators and condensers
