Spiral wound tube heat exchanger, also known as turbulent heat exchanger, double ribbed tube heat exchanger, spiral tube heat exchanger, or spiral threaded tube heat exchanger. Spiral wound tube heat exchanger is a type of heat exchange equipment developed based on the introduction of foreign heat exchange and current heat exchange equipment in China. The spiral wound tube heat exchanger made of stainless steel with high thermal conductivity, which combines internal and external threads, forms strong turbulence in the absence of fluid resistance, increasing the heat transfer coefficient inside and outside the tube.

1、 Product performance

1. Spiral wound tube heat exchanger has a high heat transfer coefficient: currently, the heat transfer coefficient can reach 14000w/㎡ in steam water heat exchange conditions ℃.

2. Spiral wound tube heat exchanger is not easy to scale: due to the 100 ° angle in the middle of the opening on the same head, the heat exchanger participates in heat transfer without dead zone; The double ribbed tube bundle drives the fluid to spiral flow, generating turbulence. Under the action of centrifugal force, the fluid has a strong scouring effect on the tube wall, making it less prone to scaling and saving maintenance costs in the later stage.

3. Spiral wound tube heat exchanger is not prone to leakage: using fully automatic welding method, the weld joint is tightly connected, the sealing cycle is long, and the thread of the heat exchange tube is similar to an expansion joint, with compensation ability. The heat exchanger has low thermal stress and is not prone to leakage.

4. Spiral wound tube heat exchanger has a small footprint: it has a large heat transfer area per unit volume, a high total heat transfer coefficient, and a small footprint, saving infrastructure costs.

5. Spiral wound tube heat exchanger is easy to install: there are two forms: vertical and horizontal, which are convenient for installation under different working conditions; Compact in size, no need for crane operation, manual installation is sufficient.

2、 Application Fields

1. Types of heat media

Spiral wound tube heat exchangers are mainly used for vapor-liquid and liquid-liquid heat exchange.

2. Product Usage

With the implementation of energy-saving and emission reduction policies by the country, the use of spiral wound tube heat exchangers has been adopted. The application of spiral wound tube heat exchangers greatly reduces waste emissions and utilizes waste for secondary use, saving production costs.

Spiral wound tube heat exchangers are suitable for chemical, heat treatment, petroleum, food, steel, metallurgy, automotive, power, building materials, textile industries, as well as heating and air conditioning refrigeration systems.
