The double-tube heat exchanger is an energy-efficient heat exchange device. It has the characteristics of high heat transfer coefficient, strong automatic descaling ability, safe and reliable operation, and has good comprehensive economic performance. It is a substitute for traditional tube heat exchangers. According to different heat media, the double-tube heat exchanger is divided into steam-water heat exchange and water-water heat exchange. It is divided into vertical and horizontal type from the installation type. It is convenient to use, complete in model, and can be specially designed according to specific conditions. It is a new type of enhanced heat transfer energy efficient heat exchange equipment.

Main features of double-tube heat exchanger â–  Double-tube heat exchanger has good anti-scaling performance: on the one hand, due to the smooth surface of the component, the fluid turbulence is sufficient, the fouling condition is destroyed, the generation of dirt is reduced, and the ripple is formed on the other hand. The tube can have slight elastic deformation under the impact of temperature difference, so it can destroy the already formed dirt. â–  The heat transfer coefficient of the double-tube heat exchanger is high: the special shape of the corrugated heat exchange tube allows the internal and external flow medium to be in a turbulent state. The boundary layer of the medium is destroyed, and the heat transfer coefficient inside and outside the tube is improved. The BHIII type further improves the shape and arrangement of the corrugations, improves the heat transfer coefficient outside the tube, and makes the heat transfer coefficient inside and outside the tube more matching, thereby again increasing the total heat transfer coefficient. Under normal conditions, the total heat transfer coefficient can reach 2.5 to 3.5 times that of a conventional light pipe heat exchanger. â–  Double-tube heat exchanger has strong anti-corrosion ability: due to high heat transfer coefficient, less material used, high corrugation strength and thin material, the heat exchange tube material is much less than ordinary tube. In this way, the heat exchange tube can be manufactured by using a material with good corrosion resistance, such as stainless steel and titanium, without increasing the cost, thereby improving the corrosion resistance of the component. â–  Double-tube heat exchanger energy saving, water saving, power saving: It has significant power saving and material saving effect in the closed loop system, and has significant energy saving and water discharge in the open loop system. â–  Double-tube heat exchanger has a simple structure: Since the bellows has moderate elasticity, it can compensate for thermal shock, so the compensation device can be eliminated and the structure is simplified!
