Shell and tube heat exchanger double-threaded tube heat exchanger cyclone heat exchanger dual profile of the turbulent (turbulent) heat exchanger is based on a traditional shell and tube heat exchanger on the application of enhanced heat transfer theory and tubes of peaks and valleys unique design, the heat exchanger performance has been a major breakthrough. It inherits the column tube heat exchanger strong, durable, safe, and reliable, but also overcome its poor heat transfer capability, easy scaling and other characteristics. Dual profile of the heat exchanger Features: 1. High double bellows Heat Exchanger double bellows heat exchanger is to rely on a unique heat transfer components - Corrugated Tube to achieve. Special section tube wave crest and trough design, the fluid flow inside and outside the tube cross-section due to the continuous mutation stark turbulence, even in the case of a small flow rate of the fluid in the inner and outer tube can form a strong disturbance, greatly improving the double lines heat transfer coefficient tube heat exchanger, the heat transfer coefficient higher than conventional tube heat exchanger 2-3 times. 2. Double bellows non-fouling heat exchanger is not blocked does not scale, smooth operation. Dual profile in the course of their work, on the one hand inside and outside of the media has always been a highly turbulent state, making medium scale difficult to deposit solid particles; on the other hand by the media impact of temperature, wave-section tube will produce a small amount of axial stretching deformation, It will follow the curvature of the inner and outer tube frequent changes, since the linear expansion coefficient of the scale layer and the wave tube sections vary widely, it will have a greater pull-off force between the dirt and the heat transfer tube, even if there will be so calm scale rupture automatically fall off, so that the dual profile of the heat exchanger remain durable and efficient heat transfer performance. At the same pipeline channel large, low pressure drop, energy-saving effect is obvious, there was no congestion. Special structural shapes 3. Two bellows heat exchanger has automatic compensation function dual profile to make it in the heated, can effectively reduce the thermal stress, no need to increase the expansion joint is provided to simplify the product structure, improved product Reliability.
