FIN TUBE HEAT EXCHANGER

摘要

PURPOSE: A fin-tube heat exchanger is provided to ensure smooth heat exchange at the fins located in the downstream side of a pipe because bent surfaces gather the flow of fluid to the downstream side. CONSTITUTION: A fin-tube heat exchanger(100) comprises a pipe(10) in which fluid flows and a plurality of fins(20) formed of metal plates and vertically arranged on the pipe. Heat exchange is made between the fluid flowing inside the pipe and the fluid passing by the outside of the fins. Each fin has a first bent surface(30) on an edge and a second bent surface(40) which is separate from the first bent surface.
