The spiral threaded tube heat exchanger unit is a new type of heat exchange equipment introduced in recent years. Compared with traditional shell and tube heat exchangers, it has undergone significant changes in material selection, structural form, external volume, and other aspects. Multiple factors have improved the appearance and performance of traditional shell and tube heat exchangers, changing their characteristics of simple structure, large volume, rough appearance, and low efficiency. It is a replacement product for 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 opening on the same head is at 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 energy (steam)

The reverse winding and spiral rising coil structure exchanges heat in a countercurrent manner, allowing steam to condense in the heat exchange tube bundle without undergoing secondary heat exchange, thus saving a large amount of steam;

（2） The spiral threaded tube heat exchanger is welded entirely of stainless steel,

Due to the use of stainless steel material for the heat exchange tube bundle and shell of the spiral threaded tube heat exchanger, which has a uniform coefficient of expansion, it can withstand a pressure of 1.6 MPa and a temperature of 400 ℃, and will not cause deformation of the heat exchanger due to unstable pressure and temperature; Temperature and pressure reduction device.

（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） Use of spiral threaded tube heat exchanger

The spiral threaded tube heat exchanger utilizes the OWEN turbulent vibration frequency criterion principle and adopts a gap design for the heat transfer tube bundle to reduce turbulent vibration phenomena and increase the service life of the heat exchanger.

（5） Spiral threaded tube heat exchanger has a low tendency for scaling and low maintenance costs

Spiral threaded tube heat exchangers have different structures, surface treatment processes, and counter current heat transfer between the two sides of the medium. While increasing the comprehensive heat transfer coefficient, the heat exchanger has self-cleaning function and a low tendency to scale. Chemical descaling can be used to clean heat exchange, which is time-saving, labor-saving, and cost-effective.

（6） Spiral threaded tube heat exchanger

Spiral threaded tube heat exchanger, where the heat medium flows through the tube side and the refrigerant flows through the shell side, does not require insulation for the heat exchanger shell

At present, the heat exchange equipment industry has a slow pace and a long product replacement cycle. Manufacturers generally invest less in research and development, and most of them imitate each other in their products, resulting in a phenomenon of product homogenization.

The characteristic of spiral threaded tube heat exchanger comes from its heat transfer coefficient. It can generally be a traditional shell and tube heat exchanger, and has better performance. Compared with traditional shell and tube heat exchangers, it can save 10%.

The exterior of the spiral threaded tube heat exchanger has also changed the crude image of traditional heat exchangers. The shell is made of stainless steel material from the cylinder to the flange, and the outer surface of the heat exchanger is polished with a mirror finish, greatly increasing its aesthetic appeal.

The characteristics of spiral threaded tube heat exchanger also come from its volume and weight being a fraction of traditional shell and tube heat exchangers, and the installation process does not require complex lifting tools and equipment, which can be completed by humans.

This heat exchanger is not suitable for low steam source pressure and water/water heat exchange conditions due to high tube side resistance.

application area

The spiral threaded tube heat exchanger has good heat transfer performance in the field of steam water heat exchange, and is applied in HVAC and domestic hot water. It also shows performance in cryogenic devices and has been applied in the chemical industry.
