Spiral threaded tube heat exchanger is a new type of high-efficiency and energy-saving heat exchange equipment introduced in recent years. It completely breaks through the design concept of traditional shell and tube heat exchangers, with significant changes in material selection, structural form, and external volume compared to traditional shell and tube heat exchangers. Multiple technological innovations have made this heat exchanger significantly surpass traditional shell and tube heat exchangers in terms of appearance and performance, changing the characteristics of simple structure, large volume, rough appearance, and low efficiency of traditional heat exchangers. It is an updated product of traditional heat exchangers.
The spiral threaded tube heat exchanger consists of a core and a shell. The core is mainly composed of heat exchange tubes, while the shell is composed of a cylinder and a head. The upper and lower heads each have two openings, and the center of the opening on the same head is 90 degrees; deg; Angle, allowing all heat exchangers to participate in heat exchange without dead zones.
（1） Spiral threaded tube heat exchanger has high heat efficiency and saves more energy (steam)
The unique reverse winding and spiral rising coil structure inside exchanges heat in a countercurrent manner, allowing steam to fully condense in the heat exchange tube bundle without the need for secondary heat exchange, thus saving a large amount of steam;
（2） The spiral threaded tube heat exchanger is made of all stainless steel welding and is resistant to high temperature and high pressure Due to the fact that the heat exchange tube bundle and shell of the spiral threaded tube heat exchanger are all made of stainless steel material, with a uniform coefficient of expansion, it has a high pressure resistance of 1.6 MPa and a high temperature resistance of 400 ℃, and will not cause deformation of the heat exchanger due to unstable pressure and temperature; No need for temperature and pressure reduction devices.
（3） Spiral threaded tube heat exchanger has a compact structure, easy installation, and small footprint Spiral threaded tube heat exchanger has a small volume, saving infrastructure investment; Lightweight and easy to install, the equipment can be directly connected to pipelines, reducing installation costs.
（4） Spiral threaded tube heat exchanger has a long service life The spiral threaded tube heat exchanger utilizes the OWEN turbulent vibration frequency criterion principle and adopts a small gap design for the heat exchange tube bundle, effectively eliminating the phenomenon of turbulent vibration and extending the service life of the heat exchanger.
（5） Spiral threaded tube heat exchanger has a low tendency for scaling and low maintenance costs The unique internal structure, surface treatment process, and counterflow heat transfer of the two side media of the spiral threaded tube heat exchanger ensure self-cleaning function and low fouling tendency while improving the comprehensive heat transfer coefficient. Chemical descaling can be used to clean the heat exchanger, which is time-saving, labor-saving, cost-effective, and effective.
（6） Spiral threaded tube heat exchanger is energy-saving and environmentally friendly Spiral threaded tube heat exchanger: The heat medium flows through the tube side, and the refrigerant flows through the shell side. The heat exchanger shell does not require insulation Technical advantage
; At present, the technology update speed of the domestic heat exchange equipment industry is slow, and the product replacement cycle is long. Manufacturers generally invest low in technology research and development, and most manufacturers imitate each other in their products, resulting in a prominent phenomenon of product homogenization.
The characteristics of spiral threaded tube heat exchangers come from their ultra-high heat transfer coefficient, which can generally be 2-3 times that of traditional shell and tube heat exchangers, while also having good energy-saving effects. Compared with traditional shell and tube heat exchangers, they can save more than 10% of energy.
The exterior of the spiral threaded tube heat exchanger has also changed the crude image of traditional heat exchangers. The shell, from the cylinder to the flange, is made of stainless steel material, and the outer surface of the heat exchanger is polished with a mirror finish, greatly improving its aesthetics.
The advantage of spiral threaded tube heat exchangers also comes from their volume and weight being only a fraction of traditional shell and tube heat exchangers, and the installation process no longer requires complex lifting tools and equipment, which can be completed manually.
This heat exchanger is not suitable for low steam source pressure and water/water heat exchange conditions due to high tube side resistance.
