| High Light | High rigidity H Type Finned Tubes ，Finned Tubes For Heat Exchangers ，High rigidity heat exchanger finned tube | ||
The fins are arranged in parallel and symmetrical, and the cross-section is shaped like the letter "H". Usually, two longitudinal fins are fixed on both sides of the base tube by high-frequency welding or mechanical pressing.
Typical parameters: fin height 15-30 mm, thickness 1.5-3 mm, spacing 20-50 mm.
Core advantages:
High rigidity: The H-shaped structure enhances anti-deformation ability and is suitable for high flow rate (>30 m/s) or particle-containing media.
Easy to clean: The straight channel reduces ash accumulation and is suitable for flue gas waste heat recovery systems (such as coal-fired boilers).
Two sets of H-shaped fins are integrated on a single base tube to form a "double H" cross-section, or the heat transfer area is increased through a cross-fin design.
Typical parameters: fin height 10–25 mm, thickness 1.0–2.5 mm, spacing 15–40 mm (staggered arrangement).
Core advantages:
Heat transfer doubled: The double-fin structure increases the heat transfer area by 40–60% compared to the single H-type.
Turbulence optimization: Cross-fins disturb the fluid and increase the Nusselt number (Nu) by 10–15%.
✦H-type fin tube: with anti-scouring and low maintenance as the core, it is suitable for high dust and high flow rate industrial scenes.
✦Double H-type finned tube: With the advantages of efficient heat transfer and compact design, it is suitable for chemical and energy systems with high heat load and limited space.
When selecting, it is necessary to comprehensively evaluate the medium characteristics (corrosiveness, dust content), thermal parameters (temperature, pressure, flow rate) and life cycle cost. If necessary, composite fins (such as H-type + spiral fins) can be customized to balance performance and economic benefits.
Power industry:
Coal-fired boiler air preheater (APH), resistant to fly ash erosion.
Gas turbine waste heat boiler (HRSG) medium pressure evaporation section.
Metallurgical industry:
Blast furnace gas waste heat recovery, medium dust content ＞50 g/Nm³.
