H-type finned tube heat exchanger elements excel in maintaining high heat transfer capacity, showcasing superior self-cleaning properties, and effectively recovering flue gas waste heat during boiler renovations. The convective heat transfer coefficient is directly proportional to fin pitch but inversely proportional to fin height and width. The overall heat transfer capacity is influenced by fin efficiency, the convective heat transfer coefficient, and the finned ratio. Note, however, that pressure drop increases with greater fin height and width.
In the pursuit of heightened heat exchange efficiency and expanded surface heat transfer, H-type finned tubes have become a staple in modern boilers and waste heat recovery systems. Originally derived from rectangular finned tubes, H-type finned tubes are distinguished by their unique grooved structure, which imparts exceptional anti-wear and anti-fouling performance.
Our products are customizable to meet specific customer requirements and situational demands. We specialize in designing and manufacturing secure, reliable, and efficient H-fin tubes. HD BOILER ensures top-notch product quality with a comprehensive assurance system. Our H-fin tubes boast high heat transfer efficiency, robust flue gas resistance, and are optimized for compact spaces.
· For special cargos, including overlength, overwidth, overheight, and overweight items, we utilize frame boxes for easier handling.
· For standard goods, ordinary containers are preferred.
· Post-loading, all goods are thoroughly reinforced to ensure secure transportation.
With 38 years of experience in research, development, and manufacturing, we offer robust production capacities and industry expertise.
