In order to solve the problem of gas poor flow uniformity in the intercooler,the non-uniform cooling tube was pro-posed.The intercooler of non-uniform cooling tube was designed and the flow uniformity was studied based on the computation-al fluid dynamics(CFD).The results show that,without changing the air chamber of intercooler,the use of non-uniform cool-ing tube can effectively improve the flow uniformity in the intercooler.Compared with the traditional intercooler,the uniformi-ty coefficient of improved intercooler increases by 2.45%-3.51%and the pressure drop increases by about 7%.
