Ingersoll Rand copper stainless steel inner finned tubes for compressor coolers are heat exchange elements used in air compressor cooling systems. They enhance heat transfer efficiency through copper or stainless steel fins, reducing oil temperature to ensure normal equipment operation.
What are Ingersoll Rand copper stainless steel inner finned tubes for compressor coolers?
Ingersoll Rand copper stainless steel inner finned tubes for compressor coolers are heat exchange elements that enhance heat transfer. By increasing the surface area, they improve heat exchange efficiency and are mainly used for post-cooling of compressor gases. Their core functions are reducing contact thermal resistance and providing corrosion and wear resistance.
Core Functions of Copper Stainless Steel Inner Finned Tubes
Heat Exchange: Utilizing copper or stainless steel fins to increase the heat exchange area, efficient heat exchange between oil and the cooling medium (such as water) is achieved, reducing oil temperature.

Copper and Stainless Steel Internal Finned Tube Material Characteristics:
Copper Fins: Excellent thermal conductivity (approximately 397 W/(m·K) for copper), suitable for general cooling needs.
Stainless Steel Fins: Strong corrosion resistance (e.g., 316L stainless steel resists chloride corrosion), suitable for high-temperature or corrosive environments.
Copper and Stainless Steel Internal Finned Tube Manufacturing Process and Structure
Fin Types:
Spiral Fins: Processed using high-frequency welding or mechanical winding processes, suitable for high-pressure and high-temperature applications.
Straight Fins: Simple structure, suitable for low-flow-rate conditions.
Tube Bundle Arrangement: A staggered layout improves heat exchange efficiency, while a straight arrangement reduces airflow resistance.
Copper and Stainless Steel Internal Finned Tube Application Scenarios
Air Compressor Oil Cooling: Reduces lubricating oil temperature and extends equipment life.
Industrial Heat Exchange: Adaptable to steam, high-temperature flue gas, and other media, meeting different pressure rating requirements (0.6-6.4 MPa). Key Selection Points for Copper and Stainless Steel Internal Finned Tubes
Material Selection: 316L stainless steel is preferred for chlorine-containing environments; 310S is selected for high-temperature applications.
Process Compatibility: Carbon steel base tubes commonly use high-frequency welding; for stainless steel fins, welding strength and temperature resistance must be considered.
