| As a heat exchanger switching equipment, industrial heat transfer process is an important integral part of, according to the structure can be divided into plate heat exchangers, tube heat exchangers, heat exchanger and expansion renewable surface transducer heater (finned tube, plate-fin). Finned tube heat exchanger heat transfer area due to the large, compact structure, is widely used in various industrial applications. Finned tube heat exchanger is the gas-liquid heat exchange device purposes the most widely used one, through the installation of the fins on a regular base to achieve enhanced heat transfer tube. Factors affecting the finned tube heat exchanger has a lot of effects, such as the geometry of the fins, fin spacing, diameter, number and arrangement of pipe, material properties, etc., in which the fin geometry plays in the heat transfer process to an important role. Based on the flow and heat transfer characteristics of the circular openings finned tube air side of the finite element analysis, circular flat fins, fin four-hole symmetry, symmetrical fins eight holes in three models to simulate the use of water-air as the working fluid, which is calculated at different wind velocity field, temperature field and Nu number distribution. Using standard computational fluid dynamics software FLUENT provided k-ε two-equation model of a computing model as applied pressure correction SIMPLE algorithm to solve it. Analysis in the presence or absence of the local heat transfer coefficient spoiler hole finned tube surface distribution. Further the number, size and location of the factors affecting the performance of the air-side heat transfer spoiler holes.
