1. Overview of design principles
The core part of the S-shaped tube heat exchanger is a heat exchanger core composed of a series of pipes bent into a specific shape. These pipes are usually arranged in a S-shaped to increase the flow length and contact area of the fluid in the pipe, thereby improving the heat exchange efficiency.

3. Classification
S-shaped tube heat exchangers can be divided into two categories according to their structural shape: immersed type and spray type S-shaped tube heat exchangers.
3.1.Immersed S-shaped tube heat exchanger: The S-shaped tube is immersed in a container containing liquid. When there is liquid in the S-shaped tube. In order to keep the entire tube full of liquid, the liquid should be fed in from the lower end of the coil and flow out from the upper end; when steam is passed into the coil, in order to avoid water hammer and blockage caused by the accumulation of cold liquid in the tube, steam should enter from the upper part and the condensate should be discharged from the lower end.
3.2.Spraying S-shaped heat exchanger: The heat transfer area of the spraying S-shaped heat exchanger is composed of a series of horizontally placed straight tubes arranged on the same vertical plane and C-shaped elbows connecting these straight tubes, and fixed on a steel frame. Above the topmost tube, a device for evenly spraying cooling water is installed. At the bottom of the heat exchanger, a water tank made of cement or steel plate is provided to collect and discharge the cooling water flowing down. During operation, the heat medium flows in the tube. In order to prevent the outer surface of the heat transfer tube from scaling and reducing the heat transfer effect, the final temperature of the cooling water should not be greater than 40~50℃.
4. Advantages
S-shaped tube heat exchangers play an important role in the industrial field. Its high efficiency heat energy conversion, stable operation, flexible application and easy maintenance make the S-shaped heat exchanger one of the important equipment in the industrial production process.
