AI Technical Summary
Technical Problem
Existing finned tubes have poor airflow guidance, resulting in poor heat transfer performance.
Method used
Spiral fins are connected to the surface of the tube, and multiple sets of airflow channels are punched at equal intervals on the surface of the fins. The depth of each set of airflow channels decreases radially, the arc length increases radially, the included angle is 30°, and the airflow channels are semi-circular to guide the airflow to the back of the heat exchange tube.
Benefits of technology
This reduces the stagnant area on the back of the heat exchange tubes, thereby increasing the effective usable area and heat transfer performance of the finned tubes.
