Customized Coaxial Heat Exchanger for High-Viscosity Oil-Based Materials

This coaxial heat exchanger was specifically designed to meet the unique requirements of a customer dealing with high-viscosity oil-based materials. These materials often present challenges such as slow flow rates, high pressure, and stringent heat exchange efficiency demands. The custom-designed coaxial heat exchanger offers the following advantages:

1. High Design Pressure and Wide Temperature Range

• Design Pressure: Capable of withstanding pressures up to 500 psi, far exceeding the limits of standard spiral plate heat exchangers.
• Temperature Range: Handles a temperature difference of nearly 200°C, ensuring stable operation even under extreme conditions.

2. Superior Heat Exchange Performance

Traditional double-pipe heat exchangers are prone to damage and inefficiencies due to significant flow velocity differences at both ends. This coaxial heat exchanger addresses these issues by optimizing the flow distribution, significantly improving heat exchange efficiency and extending equipment lifespan.

3. Exceptional Adaptability to High-Viscosity Fluids

High-viscosity oil-based materials require specialized flow channel designs to ensure efficient heat exchange at low flow rates. The coaxial heat exchanger achieves this through an innovative design tailored to the customer's specific needs.

4. Advantages Over Spiral Plate Heat Exchangers

Compared to spiral plate heat exchangers, this coaxial heat exchanger not only offers higher pressure resistance but also provides superior structural stability and ease of maintenance, making it an ideal solution for high-pressure, high-viscosity applications.

5. Internal Structure of the Coaxial Heat Exchanger

The coaxial heat exchanger consists of an inner and outer tube arranged coaxially, where hot and cold fluids flow through separate channels in a counterflow pattern for efficient heat exchange. To address high-viscosity fluids, the exchanger optimizes flow channels, adds turbulence-enhancing structures (such as helical fins), and increases flow velocity to improve heat transfer. Additionally, adjustable channel gaps ensure uniform flow and reduce resistance. The counterflow design maintains a high temperature difference, making this exchanger ideal for high-viscosity and fouling-prone applications in industries like food processing, chemicals, and pharmaceuticals.

6. coiled-type coaxial heat exchanger

In addition to tube-in-tube coaxial heat exchangers, there is also a coiled-type coaxial heat exchanger, commonly used in air conditioning systems, compressors, and pool heating applications. This type features a helical coil design, offering a compact structure, high heat exchange efficiency, and strong anti-fouling performance, making it ideal for space-limited applications that require efficient thermal management. We also manufacture this type of product and offer customization options. Feel free to contact us for inquiries.

Conclusion

This customized coaxial heat exchanger effectively addresses the challenges posed by high-viscosity oil-based materials, including slow flow rates, high pressure, and stringent efficiency requirements. It also overcomes the shortcomings of traditional heat exchangers, providing a durable, efficient, and reliable solution.
