Selecting what materials that are used in a heat exchanger is an important part of the design. The Materials need to be heat conductive whilst withstanding any corrosive properties of the mediums involved. Some materials will break down or get dirty faster than others, so upkeep and durability is very important.
Conductive metals
Good Heat exchangers rely on conductive metals such as aluminium and copper, which are popular choices. However, they’re only suitable for applications up to a specific temperature and where the fluids involved won’t react with the metals.
While conductive metals are common, ceramics or specially designed plastic polymers are a better alternative in some applications.
Fluids
The fluids used in the process are an important element. Heat exchangers for use with more corrosive fluids such as acids, chlorinated salt water and other chemicals are important as if these are going to be used, we have to carefully consider the appropriate materials to prevent corrosion.
Air
Air is also commonly used in heat exchanger systems. It has a low thermal conductivity and, therefore, often works well with an extended surface heat exchanger such as our UniAir Aluminium Cooler as well as UniFin Finned Heat Exchanger.
