Finned tube advantage
Finned tube advantage 1. High efficiency and energy saving: its heat transfer coefficient is 3000~4500kcal/m2·°C·h, which is 3~5 times higher than the thermal efficiency of shell-and-tube heat exchanger.
Finned tube advantage 2. Compact structure: the plate heat exchanger plates are closely arranged. Compared with other heat exchanger types, the plate heat exchanger has less floor space and space occupation, and the plate heat exchanger with the same heat exchange capacity is only the tube. 1/5 of shell heat exchangers.
Finned tube advantage 3. Easy to clean and disassemble: The plate heat exchanger clamps the clamping plate by clamping bolts, so it is easy to disassemble and install, and can be opened and cleaned at any time. At the same time, due to the smooth surface, the turbulence is high and it is not easy to scale.
Finned tube advantage 4. Long service life: The plate heat exchanger is made of stainless steel or titanium alloy plate, which can resist various corrosive media. The rubber pad can be replaced at will, and it can be easily installed, disassembled and repaired.
Finned tube advantage 5. Adaptability: The plate heat exchanger plate is a separate component, which can be added or removed as required, in various forms; it can be applied to various different process requirements.
Finned tube advantage 6. Without liquid, the plate heat exchanger sealing groove is provided with a liquid discharge channel, and various media will not collide. Even if a leak occurs, the medium is always discharged outward.
There are many types of finned tubes, and new varieties are constantly emerging. Finned tubes are generally classified in the following aspects in applications:
According to the processing technology classification: 1. String tube (sleeve tube); 2. Tension winding fin tube; 3. Insert tube; 4. Overall rolling fin tube; 5. Cast fin tube; 6. Welding wing The tube tube, which is divided into: high-frequency welded finned tube, submerged arc welded finned tube and the like.
According to the shape of the fins: 1. square, rectangular, circular finned tube; 2. spiral finned tube; 3. corrugated finned tube; 4. zigzag finned tube; 5. needle finned tube; 6. Longitudinal finned tube; 7. Whole plate finned tube (plate fin).
Classified by material: 1. Copper, Al, Cu/Al finned tube; 2. Carbon steel, stainless steel, carbon steel/stainless steel finned tube; 3. Cast iron (cast steel) finned tube.
Classified by use: finned tube for air conditioning; finned tube for air cooling; boiler: finned tube for water wall, economizer, and air preheater; fin furnace for various furnaces, industrial furnace waste heat recovery; Special purpose finned tubes, etc.
