Study on the applied properties of the filling foam based on the intake and exhaust device
The structure composition of the intake and exhaust device and the molding process of filled foam are introduced briefly.The heat-shielding performance of the filling foam of intake and exhaust device is simulated by using the thermodynamic module in ANSYS Workbench.The thermal insulation and water-absorbed rate of foam filled samples are carried out.The simulation and actual measurement results show that the Heat-insula-tion characteristic of filled foam is remarkable,and it can insulate the exhaust pipe from 180℃to the intake pipe not more than 61℃.Under the 0.05 MPa pressure for 24 h,the maximum water absorption rate is 0.72%,meeting the requirements for the heat-insulation characteristic and water-absorbed rate,releasing risks,and laying a certain theoretical support for its application.
