Difference between extruded aluminum fin tube and wound aluminum fin tube
The main difference between extruded aluminum fin tube and wound aluminum fin tube lies in their processing technology and heat transfer performance.
Extruded aluminum fin tube adopts the form of base tube sleeve aluminum tube, and the fins are formed by machine extrusion, so that the base of the fin fits tightly with the outer wall of the tube, thus having a high heat transfer coefficient and excellent heat transfer performance.
This process is suitable for occasions with high requirements for heat transfer efficiency, such as applications requiring efficient heat exchange.
Wound aluminum fin tube is made in the form of base tube wrapped with steel strip, and the steel strip can be made of copper, aluminum, carbon steel, stainless steel, etc.
The fins of this process are not completely fitted with the outer wall of the base tube, but are forced to stand upright on the surface of the base tube, so the heat transfer coefficient is slightly lower.
The advantage of wound fin tubes is that they are applicable to a variety of types and can be used in occasions with high quality requirements, but their heat transfer efficiency is relatively low.
Extruded aluminum fin tubes achieve a close combination of fins and base tubes through the extrusion process, providing higher heat transfer efficiency and are suitable for application scenarios with strict requirements on heat transfer efficiency.
Wound aluminum fin tubes are achieved through the winding process. Although they have a wide range of applications, they are slightly inferior to extruded aluminum fin tubes in terms of heat transfer performance.
