Inlet manifold integrated with intercooler

Abstract

The invention discloses an inlet manifold integrated with an intercooler. The inlet manifold comprises an inlet manifold body and the intercooler; a pressure stabilizing cavity is arranged on the inlet manifold body; the intercooler is integrated in the pressure stabilizing cavity; and the inlet manifold body further comprises an air inlet cavity communicating with the bottom face of the pressure stabilizing cavity and used for adjusting the air inlet direction and the boundary air space of the intercooler. As the appearance of the air inlet cavity of the inlet manifold integrated with the intercooler is optimized and the space of air of an edge and corner area of the intercooler is enlarged, air entering the air inlet cavity is prevented from being unevenly cooled when the boundary area space of the intercooler is small, the flowing direction of the air inlet face of the intercooler is adjusted, and accordingly flowing on the air inlet face of the intercooler is more even, and the temperature distribution evenness of the air outlet face of the intercooler is improved.

Description

technical field [0001] The invention belongs to the technical field of engine component design, and in particular relates to an intake manifold integrating an intercooler. Background technique [0002] At present, as supercharging technology is more and more applied to complete vehicles, the high-temperature and high-pressure air passing through the compressor needs to be cooled. The traditional intercooler cooling technology is to separate the intercooler from the intake system, and the compressor needs to be separated from the turbine. The outlet of the supercharger is cooled by the intercooler at the front end of the car, and then it is transported to the intake manifold through the pipeline. The pressure loss of the system increases, the possibility of reheating increases, the intake efficiency of the engine is reduced, and the response sensitivity of the entire system is relatively lagging, which affects the performance of the engine. Based on the problems caused by th...
