Fin tube heat exchanger is one of the most extensively researched types of heat exchangers. The most commonly used among them isSteel aluminum composite finned tube heat exchanger.
Steel aluminum composite finned tubes are the core components of heat exchangers, and their quality directly affects the performance of the heat exchanger
Steel aluminum composite finned tube heat exchangerThe performance advantages of the material
Various heat exchanger materials should be selected according to the different purposes and operating conditions of the heat exchanger. The commonly used materials currently include: pure aluminum, aluminum alloy, copper, brass, nickel, titanium, stainless steel, Inconel nickel alloy, etc. Among them, aluminum and aluminum alloys are the most commonly used.
The basic requirements for the base material of finned tube heat exchangers are: good brazing and formability, high mechanical strength, good corrosion resistance and thermal conductivity. Aluminum and aluminum alloys not only meet these requirements, but also have the characteristic of increasing ductility and tensile strength with decreasing temperature. Therefore, they have been widely used in compact heat exchangers around the world, especially in low-temperature ones
1) Aluminum has a low density and can achieve the strength of structural steel through alloying and heat treatment. Aluminum heat exchangers are used in various types of transportation vehicles, especially small cars, which will inevitably reduce their own weight and fuel consumption.
2) Aluminum has good corrosion resistance. The oxide generated by aluminum products under harsh conditions is non-toxic. Heat exchangers made of aluminum do not have to worry too much about being oxidized by air or liquid inside the tubes and becoming ineffective over time.
3) Aluminum has good thermal conductivity, especially suitable for heat sinks, evaporators and condensers used for heat exchange.
4) Aluminum has high yield strength, stamping resistance, and is easy to process and shape.
