Corrugated Tube for Heat Exchanger

Corrugated tubes are commonly used in heat exchangers due to their enhanced heat transfer capabilities. The corrugated design, characterized by a series of ridges and valleys along the length of the tube, enhances turbulence and disrupts laminar flow, resulting in improved heat transfer performance. Here are some key points about corrugated tubes for heat exchangers:

Heat Transfer Enhancement: The corrugated structure of the tube creates turbulence and enhances heat transfer by increasing the surface area available for heat exchange. The ridges and valleys disrupt the boundary layer, reducing thermal resistance and promoting better heat transfer efficiency.

Increased Fluid Velocity: The corrugated geometry induces fluid flow acceleration and enhances the velocity of the fluid passing through the tube. This increased velocity helps in preventing fouling and scaling deposition on the tube surface, ensuring better heat transfer performance over time.

Compact Design: Corrugated tubes enable the design of more compact and efficient heat exchangers. The increased heat transfer coefficient allows for a smaller heat exchanger footprint, reducing space requirements and overall costs.

Resistance to Thermal Stress: The corrugated structure provides additional rigidity and strength to the tube, making it more resistant to thermal stress and pressure fluctuations. This feature is especially beneficial in high-temperature or high-pressure applications.

Versatility: Corrugated tubes can be manufactured from various materials such as stainless steel, copper, or aluminum, depending on the specific requirements of the heat exchanger. The material selection depends on factors like temperature, pressure, corrosion resistance, and cost considerations.
