Fin Copper Tube

What is the effect of fin density of finned copper tube on heat transfer performance?

As the core component of heat exchange equipment, finned copper tube is widely used in many fields such as air conditioning, refrigeration, heat exchanger, etc. The quality of its heat transfer performance directly affects the energy efficiency and operation stability of the equipment.
What is fin density?
Fin density usually refers to the number of fins on the finned copper tube per unit length, or the number of fins per meter of tube length. As an additional heat dissipation structure on the surface of the copper tube, the main function of the fin is to increase the heat transfer surface area and improve the heat transfer efficiency. The higher the fin density, the larger the heat transfer area per unit length, and the theoretical heat transfer performance is improved accordingly.
The effect of fin density on heat transfer performance
Increase the heat transfer area and improve the heat transfer efficiency
When the fin density increases, the effective heat transfer area on the outer surface of the copper tube increases, which is conducive to accelerating the heat exchange between the fluid and the fin surface, thereby improving the overall heat transfer coefficient. Zhejiang Jingliang Copper-Tube Products Co., Ltd relies on advanced precision rolling and drawing technology to achieve precise manufacturing of high-density fins, ensure that the fins are evenly distributed and undamaged, and maximize the heat exchange effect.
Balance between fluid resistance and fin density
Although high fin density brings a larger heat exchange area, it also increases the flow resistance of air or refrigerant, affecting the fluid flow rate and heat exchange efficiency. If the spacing between fins is too small, it is easy to cause fluid turbulence and pressure drop, which may offset the advantages brought by the increase in heat exchange area. When designing the fin density, Zhejiang Jingliang combines fluid dynamics simulation to optimize the fin arrangement to achieve the best balance between heat transfer and flow resistance.
Effect of fin structure on thermal conductivity
The fins of fin copper tubes must not only ensure density, but also consider the thickness, material and shape of the fins. Zhejiang Jingliang uses high-quality copper materials and ensures uniform fin thickness and excellent thermal conductivity through precision rolling technology, which improves the efficiency of heat transfer from the copper tube body to the fins and avoids the thermal bottleneck caused by too thin fins.
The relationship between corrosion resistance and fin density
The high-density fin structure is complex, easy to accumulate dust and scale, and affect the heat exchange efficiency. Zhejiang Jingliang combines years of production experience and uses surface treatment technology to improve the corrosion resistance and stain resistance of the fins, reduce maintenance frequency, and ensure long-term stable operation.

Zhejiang Jingliang uses automated production lines and intelligent manufacturing technology to achieve precise control of fin density and size, ensuring that the heat exchange performance of each copper tube is stable and consistent, meeting the stringent quality requirements of high-end refrigeration equipment.

Fin copper tube cleaning and maintenance methods and their impact on performance

The importance of fin copper tube cleaning
Fin copper tubes increase the heat exchange area through fins and improve heat exchange efficiency. However, during long-term operation, dust, oil, scale and corrosion products in the air will adhere to the surface of the fins or the inner wall of the tube, forming a dirt layer, hindering heat transfer, resulting in a decrease in heat exchange efficiency, and even affecting the safety of equipment operation.
Zhejiang Jingliang uses high-purity copper materials and advanced processing technology to make fin copper tubes have excellent corrosion resistance and mechanical strength, but any copper tube will still be affected by performance loss if it lacks proper cleaning during use. Therefore, reasonable and effective cleaning and maintenance are the key to ensuring the long-term and stable operation of fin copper tubes.
Fin copper tube cleaning method
Mechanical cleaning method
Use physical means such as brushes, steel wool or high-pressure gas to remove dust and loose dirt on the surface of the fins. Zhejiang Jingliang's fin design takes into account structural robustness and can withstand a certain degree of mechanical cleaning without damaging the fin structure. It is a common and economical cleaning method in daily maintenance.
Chemical cleaning method
For scaling or stubborn dirt in the tube, use appropriate acid and alkali solutions for chemical reaction removal. Zhejiang Jingliang strictly controls the chemical composition and surface treatment of copper materials to ensure excellent acid and alkali resistance, supports the safe use of a variety of cleaning agents, and minimizes the corrosion of copper tubes caused by chemical cleaning.
High-pressure water jet cleaning
Use high-pressure water flow to impact and remove sediments in the fin gap and pipeline. Zhejiang Jingliang's fins are arranged tightly and evenly, combined with a sturdy structural design, to ensure that this type of cleaning method can effectively remove dirt without damaging the fins and tube walls.
