Have you also experienced such torment? Opening the car door after being exposed to the sun, the heat wave rushed in and the seats were scorching hot. Even though I reluctantly sat down and the air conditioning cooled my face, my buttocks and back, which were tightly pressed against the seat, were still hot and unbearable. It can be said that "the front is cool and the back is a sauna room".

Car seat fan

Install 'breathing lungs' on the seat

The ventilation system for car seats has emerged, and its effect is comparable to installing a breathing system on the seat, and the fan is undoubtedly its "lung" that can breathe.

The seat ventilation system directly dissipates heat from the source and quickly lowers the seat temperature. The built-in seat fan generates airflow, which is evenly discharged from the perforated leather surface through the air guide layer (blowing type) or extracts the humid and hot air from the back of the human body (suction type), accelerating the heat exchange and sweat evaporation between the human body and the seat contact surface, achieving the purpose of continuous cooling.

This configuration, which was once exclusive to luxury cars, is now rapidly sinking into more models with the wave of "internal competition" and new energy competition in the automotive industry, and is expected to become a "standard" for summer driving.

The quality of fan performance“

Determine user experience

The core of the seat ventilation system is the ventilation fan installed under the seat cushion and behind the foam surface of the backrest. The core parameters such as fan air volume, air pressure, and noise determine the cooling effect and directly affect the user experience.

Adequate air volume is the foundation for quickly removing heat, while sufficient static pressure ensures that the airflow can effectively penetrate the seat foam and clothing before acting on the body surface. Excellent noise control achieves low-noise operation. All of these require the seat ventilation fan to be able to operate in limited space and harsh working conditionsBalance noise, wind speed, and wind pressureAnd maintain long-term performance stability for tens of thousands of hours, which puts high demands on product technology and production processesThe requirements.

Four sided photoelectric fan

Reshaping the Cool Driving Experience

Four party photoelectric seat ventilation fans 10025, 11025 series, butterfly fans and other series of products, based on double ball bearing design, can achieve high wind pressure (and similar air volume) at low speed under the same conditions, with high air volume, high wind pressure, long life, low noise and other performance characteristics, committed to providing customized cool and comfortable driving experience for drivers and passengers.

For seats such as sports seats and high-performance electric seats, the companyButterfly shaped fanBy drawing in air from the axial air inlet and exerting centrifugal force, it is sent out from the radial annular air outlet to achieve "surrounding air outlet", with a maximum air volume of59m³/h(Fan speed 4600rpm, noise 54dbA). For complex high impedance seats such as zero gravity seats, the company adopts a dense thin blade design combined with centrifugal eddy current enhanced air ducts to break through the traditional fan wind pressure limit and achieve peak static pressure432Pa, can penetrate multiple layers of high-density filling material for zero gravity seats,Addressing the pain points of ventilation failure in high impedance seats.

At present, the company meets the needs of both suction and blowing through specific structural design with the same appearance, making it easy for platform applications. The products have been supplied in bulk to multiple domestic and foreign OEMs, meeting their rigorous testing and validation requirements for high and low temperature impact verification, high IP protection testing, salt spray testing, drop testing, and other tests.
