Industrial radiators (commonly known as finned radiators) are core heatexchange devices in industrial applications that use air as the heat transfermedium. By attaching fins to the surface of the base tubes, they expand the heattransfer area on the air side, enabling efficient heat exchange between gases andliquids/steam. Their key advantages lie in their compact structure, high heattransfer efficiency, and strong adaptability, making them widely used inheating/cooling processes across industries such as chemical, machinery, power,metallurgy, and HVAC
The core components of a radiator consist of base tubes, fins, tube boxes,and a frame. Using liquids (water, thermal oil, refrigerant) or steam flowing insidethe tubes as the heat medium, the fins on the outer surface enhance heat transferon the air side, thereby achieving air heating or cooling. The air-side heat transferarea is increased by 3 to 10 times compared to bare tubes.
