H-type finned tube heat exchanger elements are engineered to deliver exceptional heat transfer capabilities, boasting superior self-cleaning properties and the ability to efficiently recover waste heat during boiler renovations. The convective heat transfer coefficient directly correlates to fin pitch, while inversely related to fin height and width. Overall heat transfer efficiency hinges on fin efficiency, convective heat transfer coefficient, and finned ratio. Note that pressure drop escalates with increased fin height and width.
To maximize heat exchange efficiency and enhance surface heat transfer, H-type finned tubes have become increasingly popular in boilers and waste heat recovery applications. Originating from rectangle finned tubes, H-type finned tubes feature a unique groove structure on the fin surface, ensuring outstanding anti-wear and anti-fouling performance.
We tailor our products to meet customer specifications and situational requirements, designing and manufacturing H-fin tubes that are safe, reliable, and efficient. Zhangjiagang Hua Dong Boiler Co., Ltd. has established comprehensive quality assurance systems for stand-alone products. Our H-fin tubes exhibit high heat transfer efficiency, resist flue gas, and are optimized for compact spaces.
· For special cargos, such as those exceeding standard dimensions or weight, we choose frame boxes to facilitate easy handling.
· For regular goods, we use standard containers.
· Once the goods are loaded, we ensure they are thoroughly reinforced for secure transit.
With 38 years of extensive industry experience in research, development, and manufacturing, we possess ample production capacity.
