A finned tube heat exchanger is a kind of heat exchange equipment most widely used in gas and liquid. To achieve the purpose of strengthening heat transfer, the fins with horizontal and vertical are added to the surface of the base tube. Although there are many forms of physical structure, the basic structure is made up of parallel plate and assembled plate bundle consist of various forms of fins. It is generally made of aluminum alloy. So it has a compact structure, a high coefficient of heat transfer, and a heat transfer area per unit volume of is up to 2500 ~ 4000 m2/m3
A finned tube heat exchanger is applied and equipped with fins on one side to increase the heat transfer area, improve the degree of turbulence in the fluid and the convection heat transfer coefficient when two fluid convection heat transfer coefficient has a large difference.
