Abstract

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