Extruded Aluminum Fins for Air Cooled Heat Exchanger

Extruded aluminum fins in air-cooled heat exchangers improve heat transfer efficiency mainly by enhancing thermal conductivity, increasing heat transfer area and optimizing fluid dynamics.

Extruded aluminum fins in air-cooled heat exchangers primarily improve heat transfer efficiency in the following ways:

Extruded aluminum fins enhance thermal conductivity

Aluminum has a high thermal conductivity, enabling rapid heat transfer. The extrusion process creates a tight bond between the fins and the base tube, reducing contact thermal resistance and ensuring efficient heat transfer to the air.

Extruded aluminum fins increase heat transfer area

The fin structure significantly increases the heat transfer surface area, shortening the heat transfer path between the air and the refrigerant, thereby improving air cooling efficiency.

Extruded aluminum fins optimize fluid dynamics

Rationally designed fin shape, spacing, and arrangement guide air flow, reduce dead zones, and extend air-fin contact time, further improving heat transfer efficiency.

Extruded aluminum fins are suitable for low-temperature operating conditions.

Aluminum is highly corrosion-resistant and can withstand moisture erosion in the humid environment of cold storage, ensuring long-term stable operation.
