Working Principle
Finned tube heat exchangers 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 in the surface of 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.
