Upgrade your thermal management with our Lightweight High Efficiency Aluminum Microchannel Multi Port Flat Tube – also known as parallel flow aluminum tube or microchannel heat exchanger tube. This multi port extruded tube is the core component for automotive radiators, A/C condensers, and EV battery cooling systems.
Precision extruded as a seamless one‑piece structure, it integrates multiple parallel microchannels that dramatically improve refrigerant/coolant flow and heat exchange. Whether you manufacture automotive condenser tubes, battery liquid cooling plate tubes, or industrial heat exchangers, this lightweight heat transfer tube delivers higher efficiency, lighter weight, and uncompromising reliability. Fully compatible with R134a, CO₂, and other refrigerants.
Lightweight Champion
30–50% lighter than traditional copper heat exchangers – reduces vehicle energy consumption and extends EV range. A true lightweight heat transfer tube for modern electric vehicles.
40%+ Higher Heat Transfer
Microchannel design maximizes surface area per unit volume, delivering superior cooling and heating performance. Ideal for EV battery cooling tube applications.
Eco & Energy Saving
Works with low‑GWP refrigerants, cuts refrigerant charge, and lowers system operating costs.
Built to Last
Seamless extrusion – no welds, no weak points. Exceptional vibration, corrosion, and fatigue resistance. Made from AA3003 extruded flat tube alloy or high‑strength 6xxx series.
Tailor‑Made
Custom port count, dimensions, channel shape (rectangular / triangular), and surface treatment. Your ideal custom microchannel tube solution.
