Papua New Guinea DR rolled copper aluminum finned tube

Papua New GuineaBimetallic finned tube
- Product Description
-
1. Overview
The processing technology of copper-aluminum composite finned tube is first processed into a bimetallic composite tube by aluminum sheet and copper tube, and then mechanically cold-rolled. Using the physical characteristics of the aluminum tube, the copper tube is made as the core of the pipe, and the fin tube is closely combined with the cold-rolled aluminum fin.
2. production process
Copper-aluminum composite finned tube refers to copper tube, aluminum tube after composite-composite generally refers to a certain specification of aluminum tube sleeve on the outside of the copper tube according to the specifications of the required finned tube, and then rolled on the rolling mill.
3. features
Copper-aluminum composite finned tube radiator is widely used in heating engineering wet cooling, easy to remove the condensation water on the outer surface of the fin, in dry heating and other heat exchange occasions is not easy to form dust and scale. Copper aluminum finned tube heat dissipation material selection of high quality copper, in the manufacture of high temperature welding process. The thermal conductivity of copper is 0.17-0.6W/(m · ℃), which is much higher than other metals. At the same time, copper also has good corrosion resistance, so it can effectively resist the corrosion of acid, alkali, organic solvents and other substances when used. Due to the high thermal conductivity of copper, when welding on its surface, a large convective air channel can be formed and heat can be quickly transferred to every tiny molecule in the air, so as to improve the heat dissipation and even improve the thermal comfort. Using special treatment method on the surface of the radiator after welding can effectively inhibit the thermal resistance of the finned tube radiator itself and reduce the heat loss. Therefore, in actual use, its heat dissipation is many times higher than that of traditional steel heat sinks or aluminum heat pipes. Copper-aluminum composite finned tube has the advantages of tight bonding, low thermal resistance, good heat transfer performance, high strength, low flow loss, strong corrosion resistance, not easy to deform under long-term cold and hot conditions, and long working life. When used under the same working conditions, the thermal conductivity is large, the thermal conductivity is good, the area is small, and the appearance is beautiful.
4. Application Areas
Copper-aluminum composite finned tubes are generally used in the air heat exchange of gas outside the liquid tube inside the tube. The liquid in the tube is generally water, a mixed solution of water, and a cooling medium such as ethylene glycol. In the case of using copper pipe as the base pipe, avoid the medium in the pipe can not go steam and heat transfer oil. Excessive pressure or high temperature will lead to deformation and cracking of the pipe, easy to leak and easy to bend.
