TP321(GOST9941 12X18H10T) Corrugated Fin Tube for Air Cooler Application
YUHONG'S Low Finned Tubes are a type of finned tube characterized by a continuous external fin, helically wound around the base tube with a relatively low height. The key features of low finned tubes are as follows:
- Increased Heat Transfer: The external fins of the low finned tube significantly augment heat transfer, facilitating efficient heat exchange between the fluid inside the tube and the surrounding environment.
- Compact Design: Low finned tubes boast a compact design and offer superior heat transfer capabilities compared to plain tubes, leading to smaller equipment sizes and a reduced overall footprint.
- Reduced Material Costs: By using low finned tubes, less material is required to achieve the same level of heat transfer performance, potentially lowering manufacturing costs.
- Corrosion Resistance: Low finned tubes are commonly crafted from corrosion-resistant materials such as copper or stainless steel, prolonging the tube's lifespan and decreasing maintenance expenses.
- Increased Efficiency: Thanks to the enhanced heat transfer from the external fin, low finned tubes can operate at higher efficiency and lower costs compared to plain tubes.

Characteristics of U Bending Low Finned Tubes
- Enhanced Heat Transfer Efficiency: The design of U bending low finned tubes facilitates efficient heat exchange between the fluid flowing inside the tubes and the surrounding air, maximizing the available surface area for heat transfer.
- Compact Design: The compact design achieved through the use of U-shaped bends makes these tubes well-suited for applications requiring a considerable surface area in confined spaces.
- Flexibility: U bending low finned tubes can be manufactured using various materials such as copper, aluminum, stainless steel, or carbon steel to accommodate different fluid properties and operating conditions.
- Customizable Fin Designs: The geometric shape (simple, serrated, wavy, etc.) and spacing of the fins attached to the tubes can be altered to maximize heat transfer performance according to specific application needs.
- Corrosion Resistance: These tubes exhibit excellent corrosion resistance based on the chosen construction materials, ensuring durability and prolonged lifespan in demanding operational environments.
- Enhanced Mechanical Performance: The stable structure of these tubes, stemming from the U-shaped bends, reduces the likelihood of deformation or damage during handling, installation, and use.
