1. Equipment structure and working principle Core function: Roll low-height spiral fins or straight fins on the outer surface of metal tubes (such as copper tubes, aluminum tubes, stainless steel tubes, etc.) through mechanical processing.
Processing method: Usually cold rolling forming process is adopted to plastically deform the surface of the tube through high-precision molds or rollers to form a fin structure.
The fin height is generally low (usually 0.5-1.5mm) and the density is high, which is suitable for compact heat exchange
requirements.
Drive system: Hydraulic or servo motor drive is adopted to ensure stable and efficient processing.
2. Main features
Efficient heat exchange: By increasing the surface area of ​​the tube, the heat transfer efficiency is significantly improved, which is suitable for heat exchange scenarios that are sensitive to volume.
Material saving: Compared with traditional light tubes, low-fin tubes can achieve higher heat exchange performance at the same volume and reduce material costs.
Adaptability: It can process a variety of metal materials (copper, aluminum, titanium, carbon steel, stainless steel, etc.) and different tube diameters. Automation degree: Modern low-fin machines are mostly equipped with PLC control systems to achieve automatic feeding and molding integration.
3. Application areas
Refrigeration and air conditioning: heat exchange tubes for condensers and evaporators.
Chemical and energy: heat exchangers and coolers in petrochemicals and power plants.
Automotive industry: engine radiators, intercoolers, etc.
Food and medicine: low-temperature heat exchange equipment or heat exchange requirements in clean environments.
4. Equipment advantages
High precision: fin height and spacing are uniform to ensure stable heat exchange performance.
Low energy consumption: cold rolling process does not require heating, energy saving and environmental protection.
Long life: the formed fins are integrated with the base tube, which is corrosion-resistant and wear-resistant.
