Copper Low Finned Tube Extruded Type For Air Conditioning Units

Overview

copper low finned tube is a type of heat exchanger component used in various industrial applications, particularly in systems that require efficient heat transfer. It consists of a copper tube with spiral fins attached to its exterior. The purpose of the fins is to increase the surface area of the tube, which in turn enhances the heat transfer between the tube and the surrounding air or fluid.

Copper Material:

• Copper is chosen for its high thermal conductivity, making it an excellent material for heat exchangers. It helps in efficient heat transfer, which is critical in applications such as air conditioning, refrigeration, and heating systems.

• Copper is a highly versatile material used in many industries due to its excellent conductivity, corrosion resistance, and malleability. It comes in various grades depending on the desired properties, such as strength, thermal conductivity, and formability. Here are some of the most common copper grades:

1. C11000 (Electrolytic Tough Pitch Copper - ETP Copper)

• Properties: This is the most common grade of copper, often used in electrical wiring and components. It has excellent electrical and thermal conductivity.
• Applications: Electrical conductors, power cables, heat exchangers, and electronic components.
• Key Features: High electrical conductivity, moderate strength, good formability, and excellent corrosion resistance.

2. C10100 (Oxygen-Free Copper - OFC)

• Properties: This grade of copper is refined to be free of oxygen, which improves its conductivity and makes it ideal for high-performance electrical applications.
• Applications: Used in high-end audio cables, connectors, and some electronic applications where purity is critical.
• Key Features: Exceptional electrical and thermal conductivity, very low oxygen content, and higher resistance to corrosion.

3. C12200 (Oxygen-Free High Conductivity Copper - OFHC)

• Properties: This is another high-purity copper grade with very low oxygen content, but it’s even purer than C10100. It has superior conductivity and resistance to corrosion.
• Applications: Used in the manufacture of high-quality electrical conductors, high-performance heat exchangers, and in industries where maximum conductivity is needed.
• Key Features: Extremely high electrical conductivity and corrosion resistance.

Extruded:

• The term extruded refers to the manufacturing process where the copper tube is formed by forcing it through a mold or die to create a specific shape. In this case, it typically results in a tube with fins or grooves.

Low-Finned:

• The low finned design refers to fins that are attached or formed on the outside of the tube but are smaller and less spaced out compared to standard finned tubes. These fins increase the surface area of the tube, allowing for better heat dissipation without taking up as much space or adding as much weight as high-fin designs. They are typically placed in specific patterns to optimize airflow and heat exchange.

Advantages of Low Finned Tubes:

1. Enhanced Heat Transfer: The fin design increases the surface area, which improves the heat transfer efficiency.
2. Compact Design: Low fins allow for efficient cooling or heating in a compact space.
3. Corrosion Resistance: Copper’s natural resistance to corrosion makes these tubes durable and reliable in harsh environments.
4. Energy Efficiency: These tubes are often used in heat exchangers and radiators, where efficiency is critical for energy savings.

Applications:

• Air Conditioning and Refrigeration: Used in coils for air conditioning units, cooling systems, and evaporators.
• Heat Exchangers: Applied in various industrial and automotive heat exchangers where space and heat dissipation are a concern.
• Automotive: Used in radiators, intercoolers, and oil coolers.
• Plumbing: Sometimes used in specialized heating systems or thermally efficient plumbing systems.
