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, external volume, and other aspects 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 update of traditional heat exchangers

product mix

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 forms a 90 ° angle, allowing the heat exchanger to participate in heat exchange without dead zones.

Advantage

（1） Spiral threaded tube heat exchanger has high thermal 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 can withstand a maximum pressure of 1.6 MPa and a maximum temperature 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 the minimum gap design of the heat transfer 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 scaling 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 with heat medium flowing through the tube side and refrigerant flowing through the shell side, the heat exchanger shell does not require insulation
