Shenyang purple copper inner fin tube is a type of reinforced heat transfer tube with discontinuous fin ribs. The mechanism of enhancing heat transfer in a needle fin tube heat exchanger is to expand the secondary heat transfer surface while continuously damaging the boundary layer of the fluid through fluid disturbance, thereby effectively improving the heat transfer coefficient K. Due to the continuous expansion surface of the needle fin tube and the use of the same material as the base tube, the contact thermal resistance is eliminated, thereby greatly improving the heat transfer coefficient. Needle finned tube heat exchange elements can be widely used in various heat exchangers, such as oil coolers, air coolers, ice machine coolers, air conditioning coolers, etc. At present, there are two main types: the Swedish Sunrod needle wing tube and the integral needle wing tube, which have been introduced in detail. And introduce the heat transfer mechanism, heat transfer model, heat transfer calculation, and comparison with ordinary smoke pipes of the needle wing 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.
Introduction to Shenyang Purple Copper Inner Wing Tube ManufacturerProcess principle (taking copper and 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
