Finned Tube Heat Exchanger
It is the main heat exchange to cool or heat the air . It can heat the air with high temperature water, steam or high temperature heat conduction oil, and cool the air with salt water or low temperature water.
Finned Tube is a kind of ribbed wall, many spiral heat exchange surface or threaded tube can also be regarded as finned tube. It plays a significant role in expanding the heat transfer area and promoting turbulence, both for single-phase and phase transition convection heat transfer. Finned tube heat exchanger structure is basically the same with general Shell And Tube Heat Exchanger , but with finned tube instead of flat tube as the heat transfer surface, because of heat transfer enhancement and compact structure, it can be made into a compact heat exchanger.
The Finned Tube Heat Exchanger includes Spiral wound type Air Heat Exchanger, Extruded type air heat exchanger, String type air heat exchanger, High frequency welding air heat exchanger,etc. There are many types of finned tube, we can select the suitable type based on the operating conditions and mediums` characteristics.
