AI Technical Summary
Traditional automotive air conditioning condensers have a simple internal flow channel structure in their flat tubes, which makes it easy for the refrigerant to form a laminar flow, resulting in insufficient heat exchange and affecting heat dissipation efficiency and structural stability.
The tube body is made of aluminum alloy, combined with a zinc-nickel alloy transition layer and a zinc spray layer. It features spiral guide ridges and arc-shaped strips, an elliptical flow cavity, and an isosceles trapezoidal sealing structure at the joints to enhance corrosion resistance and heat exchange efficiency.
It significantly improves the heat exchange efficiency between the refrigerant and the tube body, extends the service life of the flat tube, enhances structural stability and sealing reliability, and improves the overall heat dissipation performance of the condenser.
