Study on the Influence of Heat Transfer Tube Type on Heat Transfer Performance of Automobile Radiator
In order to improve the heat transfer performance of automobile radiator,FLUENT software was used to simulate the fluid flow and heat transfer inside and outside the radiator tubes.The effects of the tube shape on the temperature field,velocity field,performance parameters and comprehensive performance of heat transfer enhancement were studied under the same flow area and working conditions.The results show that:under the same working conditions,compared with round tube,elliptical tube and flat tube,the waist tube has better heat transfer effect inside and outside the tube,and also leads to the increase of pres-sure drop.Through the comprehensive evaluation factor,it is found that the waist tube has better comprehensive performance inside and outside the tube than other heat dissipation tube.The research method has a certain guiding significance for the design of new heat sink and the development of single heat sink in the future.
