Floating coil radiator selected cantilevered floating coil of steam in the process of heating hot water, plus or minus the coil so that water coil surrounding the destruction of the layer of convective heat transfer. Greatly improving the heat transfer capacity, heat transfer coefficient K≥3000W / m ℃, while the role of water due to the erosion of the tube can be free-floating boom, swelling shrink freely, and thus easy to furring, if the long-term use, the accumulation of a small amount of scale by the expansion of the tube, it will be automatically de-scale, long-term use of heat capacity and therefore does not fall to good effect. Applications floating coil radiator can be widely used in industrial buildings such as chemicals, oil refining, shipbuilding and other factories and high-rise hotels, restaurants, office buildings, schools and research buildings, Yiyuan outpatient ward building heating, air conditioning, hot water supply systems and boiler room, heat station house, air conditioning room to do the structural characteristics of heat transfer equipment 1, the heat exchanger housing having ordinary steel and stainless steel plate two kinds of heat transfer tubes are copper. 2, the heat exchanger tube design pressure steam type 0.1-0.9MPa, water - water-≤1.6MPa; housing respectively with 0.6MPa, 1.0MPa, 1.6MPa three sizes, to pay attention to the selection of equipment and equipment heat performance to match. 3, due to the high heat transfer efficiency of the heat exchanger, the temperature regulator must be installed (ie thermostat) in the heat exchanger steam inlet piping to control the flow of steam and hot water temperature. 4, heat transport and installation, cranes and other lifting equipment must be used to prevent rolling, heat exchanger should be fixed with the base firmly to prevent vibration during operation, should stay out of the heat exchanger around the maintenance position. 5, using the new structure floating coil bundle, improved heat transfer capacity, while automatic descaling capacity increase; 6, the bundle can join the union, reducing the welding point, maintenance is more convenient; 7, compact structure, small size, small footprint
