Inner Grooved Tube
China Inner Grooved Tube Supplier
China Inner Grooved Tube Supplier
As a China Inner Grooved Tube Supplier, our high-quality tubes are designed for superior heat transfer efficiency. Used extensively in HVAC, refrigeration, and industrial applications, they are produced with advanced techniques and strict quality control, ensuring they meet international standards while offering competitive pricing.
Technical Specification:
- Groove Design: The tube surface has continuous or intermittent spiral grooves, increasing the contact area and altering the refrigerant’s flow.
- Enhanced Heat Transfer: The heat transfer coefficient inside the tube is 1.5-2 times greater than that of a plain tube of the same specification.
- Refrigerant Flow: The refrigerant inside the tube cools water outside by its flow, improving the tube’s heat transfer capacity.
- Expanded Usage: The outer surface can be processed with corrugated spiral grooves for wider applications.
- Customizable Features: The tube can also have radial parallel grooves (spiral angle of zero) for radiator use, with customizable smooth sections at both ends and a maximum length of 7 meters.
Main Application:
- Commercial air conditioning heat exchangers
- Central air conditioning dry evaporators
- Electronic products
- Hot conduit radiators for solar energy devices

What Is Inner Grooved Tube?
Key Features of Inner Grooved Tubes
Increased Surface Area: The grooves increase the surface area available for heat exchange, allowing for more efficient transfer of heat between fluids.
Enhanced Heat Transfer: By promoting turbulence in the fluid flowing through the tube, inner grooved tubes can significantly improve the heat transfer coefficient compared to smooth bore tubes. This results in better thermal performance.
Material Options: Inner grooved tubes can be made from different materials, with copper and aluminum being the most common. Copper offers superior thermal conductivity and corrosion resistance, while aluminum is lighter and often more cost-effective.
Advantages of Inner Grooved Tubes
Space Efficiency: Their design allows for smaller and lighter heat exchangers, which can be beneficial in applications where space is limited.
Cost-Effectiveness: By improving heat transfer efficiency, these tubes can reduce energy costs and improve overall system performance.
Versatility: Inner grooved tubes can be tailored for specific applications by varying groove depth, shape, and spacing to meet different thermal and fluid flow requirements.
Applications of Inner Grooved Tubes
Air Conditioning Systems:
Widely used in evaporators and condensers, inner grooved tubes enhance the efficiency of heat exchangers in HVAC systems.
Refrigeration Units:
They are essential in refrigeration systems, where effective heat exchange is critical for maintaining desired temperatures.
