I. Working Principle
The working principle of the car seat ventilation bag backrest ventilation system is based on the air circulation principle. Specifically, the system installs fans (or called blowers) on the foam back of the seat backrest, using the fans to draw the air inside the cabin into the ventilation layer. Subsequently, the air flows out through the breathable holes on the surface of the ventilation layer (usually located on the surface of the seat cover, which is made of perforated leather material), forming a continuous airflow circulation, thereby achieving the ventilation function of the backrest. This process is similar to the working principle of an electric fan, but it is more refined and integrated into the seat interior.
II. Types
According to the different ways of air flow, seat ventilation systems are mainly divided into two types: blower type and suction type.
Blower type: Air is blown out from the inside of the seat directly to the passenger's back, providing a more obvious cooling effect. This type is more common in models priced around 200,000 yuan.
Suction type: The fan sucks out the hot air inside the seat. Although it operates relatively quietly, in some cases (such as when a passenger gets in the car after sweating profusely), it may leave sweat stains on the seat back. The suction type is more often seen in high-end models.
III. Technical Parameters
The technical parameters of the seat ventilation system vary by model and manufacturer, but typically include the following aspects:
Working Voltage: Generally between 10.5V and 15V or 22V and 28V, to adapt to the electrical systems of different vehicles.
Working Current and Power: The working current of a single pad is typically between 1.8A and 2.5A, and the working power is between 15W and 30W. These parameters determine the energy consumption and performance of the system.
Temperature Control: The system usually has a temperature control function to ensure that the ventilation effect is within an appropriate temperature range (such as 30℃ to 70℃).
Heating Delay: To protect the motor and extend its service life, there is a 5 to 10-second delay when starting the heating load.
Noise Level: The system generates relatively low noise during operation, typically between 20 and 35 decibels, to ensure that the passenger's riding experience is not disturbed.
IV. Market Prospects
With the continuous improvement of consumers' demands for car comfort and health, the automotive seat ventilation system, as an important configuration to enhance the driving experience, has a continuously growing market demand. According to industry research reports, the compound annual growth rate of the global automotive seat ventilation system market will reach 9.4% in the next few years, indicating a promising market prospect.
In the Chinese market, with the popularization of new energy vehicles and the continuous development of intelligent connected technologies, an increasing number of vehicle models are beginning to be equipped with seat ventilation systems. This not only enhances the competitiveness of vehicles but also meets consumers' demands for high-quality driving experiences. In the future, as technology continues to advance and costs further decrease, seat ventilation systems are expected to become standard features in more vehicle models.
