Finned Tube Radiator for Thermal Oil

Finned Tube Radiator for Thermal Oil

Structural Features

Base Tube Material: Primarily seamless steel pipes, stainless steel pipes, or carbon steel pipes such as carbon steel, SS304/316L stainless steel, etc., are used to ensure stable circulation of thermal oil under high-pressure and high-temperature conditions.

Fin Design: Fins are attached to the outer surface of the base tube via processes like high-frequency welding, winding, or rolling. Materials include aluminum, copper, and hydrophilic aluminum. High-frequency welded fins form a robust bond with the tube body, offering high-temperature resistance and vibration tolerance, making them suitable for thermal oil's high-temperature operating conditions.

Tube Bundle Arrangement: Typically arranged in cross-flow or parallel configurations to optimize fluid flow patterns, enhance turbulence, and reduce dust accumulation or scaling.

Working Principle

High-temperature thermal oil flows within the base tubes, transferring heat through the tube walls to the fins. The fins significantly increase the contact area with the surrounding fluid (e.g., air, cooling water), accelerating heat transfer. The heated fluid generates natural convection or forced convection driven by a fan, thereby achieving cooling or heating of the thermal oil.

Primary Functions

Heating Function: Serves as the primary heater by utilizing heat sources (e.g., coal, gas, electric heating) to heat the thermal oil. The heated oil then transfers heat through the finned tubes to process fluids, such as materials in chemical reactors or air in drying equipment.

Waste Heat Recovery: Utilizes residual heat from high-temperature thermal oil to heat other low-temperature fluids, improving the system's energy efficiency.

Cooling Function: When system temperature control is required, heat exchange occurs between the finned tubes and cooling water or air to prevent thermal oil overheating and decomposition.

Advantages & Features

High-Efficiency Heat Exchange: Compared to standard smooth-tube heat exchangers, fins increase heat transfer surface area by 3–10 times, boosting efficiency by 50%–80% for rapid heat transfer.

Stable & Reliable: Constructed from corrosion-resistant metals and reliable manufacturing processes, ensuring long-term operation under high-temperature, high-load conditions with minimal damage. Service life reaches 10–15 years.

High Adaptability: Customizable specifications, materials, and configurations to meet diverse industrial requirements based on process demands and site conditions.

Application Fields

Widely used in chemical, food, textile, dyeing, pharmaceutical, and other industries for processes such as chemical reactor heating, food processing drying, warehouse heating, and pharmaceutical drying.
