Large section multi-channel folding pipe is a special type of pipeline widely used in fields such as heat exchange and fluid transmission. Its structural characteristics are mainly reflected in section design, channel layout, folding form, and material combination, as follows:
1、 Large section design: Balancing flow and structural strength
Large cross-sectional size: usually refers to a pipeline with a larger cross-sectional area (such as a diameter or side length significantly larger than conventional pipelines), which can meet the transportation needs of high flow fluids (liquids or gases).
Strong structural stability: Large section designs are often combined with thickened pipe walls or reinforced support structures to resist fluid high pressure or external environmental pressure, avoiding pipeline deformation or rupture.
2、 Multi channel layout: efficient diversion and heat transfer
Parallel independent flow channels: The interior of the pipeline is divided into multiple independent small flow channels (ranging in number from a few to dozens), which may be circular, rectangular, flat, etc. Each flow channel can transport the same or different fluids.
Functional diversity:
Split flow conveying: Distribute fluid from a single inlet to multiple outlets to achieve uniform distribution (such as industrial water supply and air conditioning systems).
Heat exchange efficiency: When there is a temperature difference between fluids in different channels, the multi channel design increases the contact area and heat exchange efficiency (such as radiators and core components of heat exchangers).
Media isolation: It can simultaneously transport fluids with different properties (such as corrosiveness and large temperature differences) to avoid mixing or reaction.
3、 Folding form: combining compactness and expandability
Folding structure design: The entire pipeline is formed by folding, bending, or stacking, rather than the traditional straight tube shape. Common forms include U-shaped folding, serpentine folding, and stacked folding.
Core advantages:
Space saving: The folding form significantly shortens the length of the pipeline in the straight direction, allowing it to be arranged in limited spaces (such as car engine compartments and small heat exchange equipment).
Extended flow path: Folding increases the flow path of fluid inside the pipeline, prolongs heat transfer or reaction time, and improves efficiency.
Flexibility and cushioning: Partial folding structures have a certain degree of elasticity, which can alleviate thermal expansion and contraction stresses caused by fluid impact or temperature changes.
4、 Materials and Forming: Adapting to Structural Characteristics
Material selection: High thermal conductivity and strength materials (such as aluminum alloy, copper alloy, stainless steel, etc.) are often used, and some scenarios may use plastic or composite materials (for low-pressure and corrosion-resistant requirements).
Integrated molding: The separation and folding structure of the flow channel is usually integrated through processes such as extrusion, stamping, and welding to reduce interfaces, lower leakage risks, and ensure the accuracy of the flow channel dimensions.
5、 Strong adaptability: customization and multifunctional integration
Customizable channels and cross-sections: The number, size, distribution, folding angle, and number of layers of channels can be customized according to specific application scenarios to meet the needs of different flow rates, pressures, and heat transfer efficiencies.
Composite function integration: Some designs will add turbulence structures (such as protrusions and ripples) in the flow channel to further enhance turbulence effects and improve heat transfer or mixing efficiency.
