Introduction XF floating coil heat exchanger is a company based on flow-induced vibration and non-destructive mechanism based on the principle of heat transfer components specially designed. Internal drive components using original level hanging plate structure, the shell is set too cold baffle means and devices, heat transfer, cleaning effectiveness is greatly increased. The products are divided into hot - and (semi) displacement two categories, suitable for urban heat exchanger network field, chemical medium cooling, thermal waste heat recovery systems, HVAC, hot water supply, which has the following characteristics: 1, energy-saving effect of heat transfer element at low frequency induced vibration and prevent damage to the heat transfer element resonance and reduce noise, vibration and induce improve heat transfer components of the fluid velocity near the wall to enhance heat transfer efficiency to the enhanced heat transfer purposes. Set inside the shell deflector device to guide the flow of the heated fluid tortuous enhance heat transfer. In addition, the soda is also a heat exchanger condensate subcooling means, further cooling the condensate, to fully absorb the heating medium heat, increase heat transfer efficiency. 2, the heat quickly that the heat exchanger with high efficiency heat transfer performance and compact design that can be heated in the water heat exchanger to heat up quickly to meet user requirements. 3, easy to scale the level of heat transfer components unique hanging plate structure, the flow-induced vibration at high frequencies, so that the dirt off automatically, while a sudden change in wall temperature of the heat transfer element stress also produce changes, coupled vibration induced more accelerate the rate of soil erosion, so the letter series XFJ Tankless floating coil heat exchanger with automatic cleaning function. 4, less prone to leakage, safe and reliable XFJ Tankless floating coil heat exchanger traditional brazing process improvement for the use of bonding process, eliminate the brazing rupture, leakage situation HTM, and easy maintenance, greatly improve the reliability and service life of the equipment. 5, the device is compact, small size, small footprint Second, the floating coil heat exchanger overview of the Heat Exchanger Tube chosen cantilevered floating coil, the steam heating hot water in the process, so Coil tube bundle to produce a high frequency vibration, prompting the water coil surrounding the destruction of the layer of convective heat transfer. Greatly improving the heat transfer capacity, heat transfer coefficient K≥3000W / m2 ℃, and because the water in the scouring action of the coil so that the cantilever can float freely, ease of expansion and contraction, and therefore difficult to furring, if long-term use, the accumulation of a small amount scale, through the free expansion of the tube, will be able to automatically de-scale, long-term use of heat capacity and therefore does not fall to good effect. Applications of the heat exchanger can be widely used in industrial and civil construction, such as heating chemicals, oil refining, shipbuilding and other engineering and high-rise hotels, restaurants, office buildings, schools, research buildings, hospitals and outpatient wards and other buildings, air conditioning, hot water supply series heat transfer equipment to do the boiler room, heat station house, air conditioning room. Use of a heat exchanger shell has two kinds of ordinary steel and stainless steel, heat transfer tubes are copper. 2, the heat exchanger tube design pressure steam type 0.1-0.9MPa, water - water-≤1.6MPa; shell were supporting 0.6MPa, 1.0MPa, 1.6MPa three specifications. Pay attention to the heat source and device performance to match the selection of equipment. 3, due to the high efficiency of the heat transfer, you must install the thermostat (ie thermostat) in the heat exchanger steam inlet piping to control the flow of steam and hot water temperature. 4, the device has an automatic cleaning function, but in some corner, some may still not be off the scale, dirt once every six months should be clear, clear scale thermal shock method can be used, as follows: (1) First, put the net in the housing water (2) closed near the outlet (3) to open the intake valves and condensate valve, drain pipe memory of water, condensate and then close the valve, about 5-6 minutes suddenly closed inlet valve, open the cold water valve and discharge valve so that the heating pipe suddenly cooled, drain off the scale at the same time, 5-6 times in a row in addition to all of the net, the device continues to be put into operation. 5, the heat transport and installation, you must use cranes and other lifting equipment to prevent rolling, heat exchangers should be fixed firmly foundation to prevent vibration during operation, should stay out of the heat exchanger around the maintenance position.
