Double-piping tube heat exchange unit

Overview

SWSG series double-coiled tube heat exchange unit is another high-efficiency heat exchange equipment developed by our company's scientific research personnel based on the characteristics of double-coiled multidirectional creep. Its heat transfer coefficient can reach above 6000w / m2.K. ℃, The heat exchange effect is far superior to the same type of heat exchange equipment, and is 3 to 4 times that of other heat exchange equipment. It is made of copper tube with high thermal conductivity through special processing to form internal and external threads. When the internal and external fluid passes through the thread, it creates strong disturbances, avoiding the laminar flow of liquid along the tube wall and reducing the heat transfer effect of the tube wall. The thread has thermal compensation ability, can control scale formation and growth through thermal expansion and contraction, has anti-scale, self-scale cleaning ability, avoids heat island effect, prolongs the service life of the heat transfer tube, and enhances the heat transfer effect.

Traditional tube-and-tube heat exchangers do not disturb when liquid flows in straight-walled risers. According to the principle of fluid mechanics, liquids will form laminar flow on the straight-walled tubes. According to the laws of thermodynamics, laminar flow has a great effect on heat exchange. Large, the thermal conductivity of the tube is greatly reduced, affecting the heat transfer effect. In addition, the two walls are prone to cold and heat effects during heat exchange between the two media. The vertical wall risers will rupture after a long time, which affects the normal use of the heat exchanger. In addition, since the liquid flows in the vertical wall riser, there is no disturbance, and impurities in the fluid are easily deposited or scaled on the wall of the tube, which affects the heat exchange effect, and even generates a heat island effect, which accelerates the damage of the tube. The new-generation double-tube heat exchanger developed by our company absorbs and introduces advanced technologies at home and abroad, overcomes and avoids the above disadvantages, and is an environmentally friendly and energy-saving high-tech product. The double-tube heat exchanger makes the flow rate and direction of the liquid in the double-tube continuously change, and makes the liquid move in three dimensions, which greatly improves the heat exchange efficiency, avoids the deposition and growth of scale, and plays a self-cleaning role. In addition, the double-walled pipe is flexible, and has automatic compensation effect in places with large temperature and pressure differences. The stress on the tube sheet and the cylinder is small, and it has a strong ability to adapt to changes in working conditions. It is medium and low. Safe and reliable heat exchanger for pressure system.
