Custom Coil Tube Heaters from China Suppliers & Factory - Efficient Heat Exchangers for Easy Assembly & Maintenance
Description
The coil heater is a type of heat exchanger developed based on the introduction and absorption of international heat exchange products from the 1980s. This product is novel, easy to assemble, easy to maintain, and has good performance.
The heating element of this exchanger adopts a suspended floating coil structure. During the heating process, due to the centrifugal force of steam inside the coil, the coil bundle generates high-frequency vibration, which destroys laminar heat transfer and generates high heat transfer capacity.
High-frequency vibration destroys laminar heat transfer, yielding an exceptional heat transfer coefficient.
K ≥ 3000W/m² ℃The cantilever free end of the coil expands and shrinks freely, causing alkaline attachments to automatically leave the pipe wall.
Structural Features
The coil heater is also a boiler feedwater heating device. This heater replaces the bulky high-pressure water chamber and tube plate in the original "tubular" or "U-shaped tubular" heaters with two main pipes, greatly facilitating manufacturing and maintenance work, and reducing leakage points. In addition, due to the same material and small difference in wall thickness between the riser and heat exchange tube, their welding performance is significantly better than other types. In addition, the spiral tube has good elasticity and does not generate temperature difference stress, so the possibility of heat exchange tube joints cracking will be much lower than other types of heaters.
Due to the use of spiral tubes in the heat exchange tube, the high-pressure water inside the tube is always in a turbulent state without a stagnation layer. Therefore, its heat transfer efficiency is significantly higher than other types, and its efficiency can be improved by 10% compared to the "U-shaped tube" high-pressure heater. In addition, high-pressure water in turbulent state is less prone to scaling on the pipe wall, reducing thermal resistance and cleaning workload, which can extend the service life of the equipment and greatly improve the economic benefits of the user.
