Composite fin fin tube, heat dissipation tube

Composite fin tube, also known as aluminum rolling pipe is made of aluminum pipe and other metal pipe overall rolling, no contact heat resistance, good heat transfer performance, high corrosion resistance, small flow loss, heat resistance to shock and mechanical vibration, the performance is good in thermal expansion, and has considerable expansion heat exchange surface, made of heat exchanger, effect ahead of string or winding, and other types of radiator.

Steel and aluminum composite fin pipe is a cooling pipe made of steel (or stainless steel) pipe and aluminum pipe composite before rolling the fin. Copper aluminum fin pipe is a composite copper pipe and aluminum pipe and then rolled out of the fin cooling pipe. It is widely used in the low-temperature difference heat transfer process.

Steel and aluminum composite pipe and copper and aluminum composite fin tube, the surface are anodized treatment, beautiful and generous color, and can effectively prevent surface corrosion.

The fin tube is a heat transfer element. In order to improve the heat transfer efficiency, usually on the surface of the heat exchange pipe through the fin, increase the outer area (or internal surface area) of the heat exchange pipe, so as to achieve the purpose of improving the heat exchange efficiency, such a heat exchange pipe. As a heat exchanger element, the fin tube works under the condition of high temperature flue gas for a long time. For example, the fin tube for boiler heat exchanger has a harsh environment, high temperature and high pressure and corrosive atmosphere, which requires that the fin tube should have a high performance index.
