The seat ventilation of BMW 5 Series is to add a fan on the foam back of the seat cushion and backrest, and use the fan to suck air into the ventilation layer, and then the air flows upward from the surface of the ventilation layer through the heating pad to the surface of the seat cover (the seat cover is made of perforated leather), so that passengers can use the ventilation function to disperse the sweat on their hips and backs in hot weather, which brings comfort to passengers.
Bmw 5 series air conditioning system is mainly composed of air outlet device, special material for air permeable layer and patented air guide layer for pressure prevention, wind power adjustment and wire assembly device. By connecting the air conditioning system of the original vehicle, the front air guide device is connected to the corresponding forced mute fan to pressurize the cold air into the seat sponge, and then passes through the air guide layer with patented technology of front-end vehicle modification, and part of the pressurized cold air will be directly blown to the surface of the dermis through holes in the dermis, and the other part will be cooled in a large area inside the dermis through the air guide layer with patented technology. All details and technical treatment strictly test the practical experience of technicians.
In order to ensure the long-term tightness of seat ventilation, BMW 5 Series is equipped with a patented air guide layer device inside the seat ventilation. It is one of the three main components in the whole ventilation system, and it has 250,000 experiments of extrusion without deformation, which is directly related to the comfort of the modified seat and the leather fullness after long-term riding, ensuring uniform ventilation in a large area inside the whole seat!
