— Introduction to 3-D Finned Tube
The groundbreaking three-dimensional inner finned tube, invented by our Chairman and Senior Engineer, Wang Diancan was honored with the Eureka Invention Gold Award at the 39th Brussels World Expo. Representing a new frontier in reinforced heat exchange pipe fittings, this innovation surpasses all existing domestic and international internal reinforced heat exchange pipe fittings in heat transfer performance.
Engineered for superior heat transfer within air tubes, our 3D inner finned tube achieves up to 5.8 times the heat transfer of conventional light tubes under identical operating conditions. For fluids with high Prandtl numbers, its enhanced heat transfer ratio can even surpass this figure. In condensation and boiling heat transfer scenarios, the efficiency of our finned tubes is 3-5 times and 2-5 times higher, respectively, than that of bare tubes under similar conditions.
Our range of mass-produced enhanced heat transfer tubes includes the 3D inner finned tube, 3D outer finned tube, double-sided 3D tube, and variable density 3D inner finned tube. Additionally, we can customize three-dimensional inner finned tubes and outer finned tubes, threaded tubes, flat tubes, and harmonica tubes to meet specific customer requirements.
The principal mechanisms driving enhanced unidirectional fluid convective heat transfer through our three-dimensional inner finned tubes include:
· Expanded heat exchange area
· Turbulence augmentation caused by rib disturbance sources
· Reduction in thermal boundary layer thickness due to fluid acceleration near ribbed walls
· Small equivalent diameter of the three-dimensional inner rib tube
· High heat transfer coefficient resulting from fluid lateral erosion of three-dimensional ribs
· Periodic vibration of fluid inside the pipe
· Roughening of the inner tube wall during three-dimensional rib processing
Our three-dimensional finned tube heat exchangers have been successfully implemented in over 30 enterprises across various industries, delivering exceptional results. With an annual processing capacity of 1000 tons, we offer energy-saving technology transformations, design and manufacturing of various 3D inner finned tube heat exchangers, and processing of 3D finned tubes with customer-supplied materials.
Join us in harnessing the potential of three-dimensional finned tube technology for enhanced heat transfer across diverse industries. We are committed to providing unparalleled service and support to our valued customers.
