There are significant differences in structure, working principle and effect between the blowing type and the suction type of car seat ventilation. The following is a detailed analysis of the structural differences and effect comparison between the two:
1. Structural differences
Blowing type:
The structure is relatively simple, suitable for seats with simple ventilation area structure, A-side shape without too many grooves or other special shapes.
The working principle is that the fan generates airflow, blows it into the 3D fabric layer through the ventilation duct, and then passes through the 3D fabric layer, heating pad, and leather cover in turn to achieve the ventilation function.
Suction type:
The structure is relatively complex, suitable for seats with complex ventilation structure, too many grooves or other special leather shapes.
The working principle is that the fan generates airflow and blows it into the 3D fabric layer, and then blows the airflow to the heating pad and cover through the ventilation duct designed on the foam. At the same time, the air is sucked from the seat surface and discharged from the bottom of the seat.
2. Effect comparison
Blowing type:
Advantages: The cooling effect is more direct, and the driver and passengers can directly feel the existence of ventilation, similar to the effect of blowing a fan in summer.
Disadvantages: The air blows directly to the human body, which is not good for human health, especially the seat ventilation with air conditioning, which is easy to cause back pain. For women with special physiological cycles, it may also cause more serious damage.
Application: Blowing is widely used in low-end and mid-range models, and most of the seat ventilation modified later also adopts blowing.
Suction type:
Advantages: The air volume is softer, and the air flows through the skin surface of the driver and passengers, taking away heat and sweat. The driver and passengers can feel cool but will not be blown by the wind. In addition, the structure is more complex and the cost is higher, which is usually used in mid-to-high-end models.
Disadvantages: The effect is not obvious when you just sit on it. It takes a period of operation for the overall temperature in the car to drop, and the feeling will be better. In addition, if you sit on it when you sweat a lot, there may be sweat stains on the backrest when you get off the car.
Application: The suction method is widely used in mid-to-high-end models. In order to provide a better driving experience, some models even use both blowing and suction methods at the same time. Blowing is used to quickly cool down at low air volume, and suction is used to ensure the softness of ventilation at high air volume.
In summary, blowing and suction have their own advantages and disadvantages, suitable for different models and driving needs. When choosing, consumers can weigh according to their actual needs and budget.
