Optimization of cooling fin structure of air-cooled oil-free scroll compressor
摘要
Abstract
In order to further improve the heat dissipation performance of oil-free scroll compressor air-cooled system,the profile,cross-section and size of the heat dissipation fins were optimized.On the basis of Bessel curve,a new fin profile was constructed,and the cross-section of the fin with good coo-ling effect was determined.Then the influence of each size of the fin on the heat dissipation was further studied by orthogonal test,and the optimal size combination was determined.The results show that the heat transfer performance of the fin profile based on the Bessel curve is better.Rectangular cross-section has better heat dissipation effect in current special heat dissipation structures.The significant order of influence on average temperature in solid domain is fin spacing,fin thickness,and the signifi-cant order of influence on inlet and outlet pressure drop is fin spacing,fin thickness.The optimal size combination is 3.0 mm for fin spacing and 3.5 mm for fin thickness obtained by orthogonal test.After optimization,the average temperature of scroll disk is reduced by 15.88%,significantly improving the heat dissipation performance of the air-cooled system,and providing a reference for the research of the heat dissipation fins of the air-cooled system of oil-free scroll compressor.关键词
