Application of CFD Technology in the Optimization of Air Chamber Structure of Intercooler

Taking the air-cooled intercooler as the research object,the parameter geometric modeling of the inner cavity and internal stiff eners of the intercooler air chamber is made,and the geometric model is used to simulate the internal flow field of the three-dimensional simulation to calculate the intercooler,the internal flow resistance loss and the flow rate of each flat tube in the intercooler core body,thereby obtaining the pressure loss and flow balance of the entire intercooler.The research results show that the internal stiff eners in the air chamber of the intercooler will hinder the flow of fluid regardless of the arrangement,thereby increasing the flow resistance;arranging the stiff eners parallel to the flow direction has the best internal pressure drop;the angle of the stiff eners will aff ect the flow Internal flow balance.The size of the inner cavity of the air chamber of the intercooler will directly aff ect the internal pressure drop.The smaller the inner cavity,the higher the gas flow rate and the greater the pressure loss inside the air chamber;however,the reduction of the local cavity can increase the gas flow rate.In some intercooler designs,increasing the flow rate can improve the flow uniformity of the core.
