Abstract: The application of waterway system in passenger cars mainly includes cooling and heating. Aiming at large and medium-sized rear mounted passenger cars, this paper expounds and analyzes the structural layout of waterway system, cooling subsystem and heating subsystem of the whole car, so as to solve the influence of gas generated in the two subsystems on engine cooling and heating efficiency of the car, the corresponding gas purification design schemes are put forward.
