Shenyang small-diameter copper aluminum finned tube is a type of heat exchange component. In order to improve heat transfer efficiency, fins are usually added to the surface of the heat exchange tube to increase the outer surface area (or inner surface area) of the heat exchange tube, thereby achieving the goal of improving heat transfer efficiency. This type of heat exchange tube.
Single and bimetallic finned tubes:
Our company can provide over a hundred commonly used specifications of single, bimetallic rolled finned tubes and various special specification sheets to our customers. Bimetallic rolled finned tube. Copper and aluminum rolled finned tubes are made by rolling copper or aluminum tubes as a whole, with no contact thermal resistance, high strength, heat resistance to shock and mechanical vibration, good thermal expansion performance, and considerable expansion heat transfer surface. Heat exchangers made of this finned tube have better performance than those made of string or wound plate heat exchangers. Widely used as heating, drying, condensing, and cooling equipment in the process of petroleum, chemical, metallurgical, textile, electromechanical, light industry, pharmaceutical and other industries.
The overall rolled fins are smooth and free of burrs, wrinkles, and easy to clean. When wet cooling is used in heating and air conditioning projects, condensed water on the outer surface of the fins is easily removed, and dust and scale are not easily formed in drying, heating, and other heat exchange situations.
The aluminum rolled finned tubes and copper rolled finned tubes produced by our factory have undergone anodizing treatment on their surfaces, resulting in a beautiful and elegant color that can effectively prevent surface corrosion.
Shenyang small caliber copper aluminum finned tube manufacturer introduces the process principle (taking copper aluminum as an example):
Rolled on specialized copper or aluminum tubes using specialized machine tools, it has no contact thermal resistance, high strength, resistance to thermal and mechanical vibrations, good thermal expansion performance, and a considerable expansion heat transfer surface. It is corrosion-resistant, easy to clean, and has a beautiful appearance. The heat exchanger made of this type of finned tube has a considerable expanded heat transfer area, and the effect is better than that of the series or wound plate heat exchanger. The product is suitable for working environments with hot air temperatures below 250 degrees Celsius
Specification range:
Tube thickness: 1mm-10mm Fin tube length: ≤ 23m Fin height: 1mm-30mm Fin thickness: 0.3mm-4.0mm Fin spacing: 2.0mm-5mm
