I. Product Introduction:

The corrugated tube heat exchanger is a new type of high - efficiency heat transfer and energy - saving heat exchange equipment, also known as a bellows heat exchanger or a turbulent flow heat exchanger. It is named according to the shape of the bellows or the form of fluid flow.

The corrugated tube heat exchanger is based on the traditional shell - and - tube heat exchanger. By applying the enhanced heat transfer theory and the unique design of the peaks and valleys of the heat exchange tubes, the performance of the heat exchanger has made a significant breakthrough. It inherits the advantages of the shell - and - tube heat exchanger such as being sturdy, durable, safe, and reliable. At the same time, it overcomes the shortcomings of poor heat transfer capacity and easy fouling. When the medium flows through the corrugated tube, obvious disturbances are generated inside and outside the tube, blocking the thickening of the boundary layer, strengthening heat transfer, and improving the heat transfer efficiency. The special structural shape of the corrugated tube can generate low - frequency micro - vibrations under the action of the medium, which has a strong self - cleaning effect and is not easy to foul. Moreover, it has an automatic thermal stress compensation function and does not require the addition of expansion joints. The characteristics of the corrugated tube heat exchanger, such as high thermal efficiency, small size, stable performance, safety, and reliability, make it widely used in urban central heating, power plants, petroleum, chemical industry, light industry, pharmaceutical industry, and the hot water supply and heating systems of civil buildings.

II. Performance Characteristics:

1. High Heat Transfer Efficiency

The corrugated tube heat exchanger is achieved by relying on a unique heat transfer element - the corrugated tube. The special design of the peaks and valleys of the corrugated tube causes the fluid to form a strong turbulent flow due to the continuous sudden changes in the cross - section inside and outside the tube during fluid flow. Even when the flow velocity is very small, strong disturbances can be formed both inside and outside the tube, greatly increasing the heat transfer coefficient of the heat exchange tube. Its heat transfer coefficient is 2 - 3 times higher than that of the traditional tube heat exchanger.

2. No Fouling, Blockage, or Scaling, and Stable Operation

During the working process of the corrugated tube, on the one hand, the media inside and outside the tube are always in a highly turbulent state, making it difficult for solid particles in the media to deposit and scale. On the other hand, affected by the temperature difference of the media, the corrugated tube will produce a small amount of axial expansion and contraction deformation, and the curvature inside and outside the tube will change frequently. Since the linear expansion coefficients of the scale layer and the corrugated tube are very different, a large pulling force will be generated between the dirt and the heat exchange tube. Even if there is scale deposition, it will crack and fall off automatically, so that the heat exchanger can always maintain a long - lasting and high - efficiency heat transfer performance. At the same time, the pipeline channel is large, the pressure drop is small, the energy - saving effect is obvious, and there is no blockage problem.

3. With Automatic Compensation Function

The special structural shape of the corrugated tube can effectively reduce the thermal stress when heated, eliminating the need for expansion joints. This simplifies the product structure and improves the reliability of the product.

4. Reliable, Safe, and Sturdy

This product has a short sealing perimeter. The existence of peaks and valleys enhances its axial expansion and contraction ability, effectively reducing the temperature difference stress and enabling it to adapt to large changes in temperature difference and pressure. Therefore, there will be no leakage phenomenon caused by the rupture of the tube mouth. The unique connection process between the baffle and the corrugated tube extends the service life of the heat exchanger.
