Features:：
Spiral wound heat exchangers are mainly composed of spiral wound tube bundles, shells, tube sheets, and spacers.Heat exchange tubes are typically wound in reverse on the central cylinder at a helix angle of 3°–20°.This forms a multi-layered, three-dimensional spiral channel.This structure increases the length of the heat exchange tubes.It can also maintain the pressure balance of the fluid in the shell side and the average heat energy distribution.
Product principle:
When the fluid flows in the spiral channel,This will generate a strong secondary circulation.This will disrupt the thermal boundary layer.The fluid near the wall swirls along the channel.Another portion of the fluid flows axially along the wall surface.Axial vortices are generated by the raised spiral grooves.This causes boundary layer stratification and disturbance, thereby accelerating heat transfer.
Performance advantages:
High heat exchange efficiency:
The unique structure results in excellent turbulence and a high heat transfer coefficient.Its heat exchange capacity is 3-7 times that of traditional heat exchangers, and its heat transfer coefficient can reach up to 14000W/m²℃.
Compact structure:
For the same heat exchange capacity, its volume is approximately 1/10 that of a traditional heat exchanger.It can save a lot of space resources.It is also lightweight and easy to install.
Strong resistance to staining:High flow rates and smooth pipe walls reduce fouling rates by 70%.The cleaning cycle is extended, and maintenance costs are reduced.
Stable operation:
The all-welded structure reduces the risk of leakage.The self-compensating thermal stress design of the tube bundle eliminates the risk of equipment damage caused by thermal stress.Long service life.
Spiral wound tube heat exchanger,Also known as spiral wound tube heat exchanger or spiral threaded tube heat exchanger,It is a high-efficiency industrial device used for vapor-liquid heat exchange.It primarily serves the fields of distillation reflux, waste heat recovery, HVAC systems, and chemical and food processing.
