Heat-Dissipation Office Chair

The LiberNovo Omni dynamic ergonomic office chair OC-1Pro from Qingxian brand features heat-dissipation functionality. Its heat-dissipation design is achieved through the synergy of a two-speed ventilated seat cushion and a high-speed fan, with the specific mechanism as follows:

1. Core Heat-Dissipation Component: Suction Fan
The seat cushion of this chair is equipped with a built-in suction fan that rotates at 4,000 revolutions per minute. By rotating at high speed, it creates a negative pressure environment, actively drawing in the hot air and moisture from the surface of the seat cushion into the internal circulation system. The fan adopts a suction design rather than a blowing design, which avoids the discomfort caused by direct airflow impact on the skin while more efficiently removing heat. In the low-speed mode, the fan operates at a lower rotational speed, suitable for daily office scenarios, maintaining the dryness of the seat cushion through a continuous gentle airflow. The high-speed mode, on the other hand, achieves rapid cooling through full-power operation, suitable for long periods of sitting or high-temperature environments.

2. Adaptability of Dual-Mode Adjustment
The chair offers two modes: low-speed and high-speed, allowing users to flexibly switch according to the ambient temperature and their physical sensations. The low-speed mode (approximately 2,000-3,000 revolutions per minute) maintains basic breathability with low noise and low energy consumption, suitable for air-conditioned rooms or mild climates. The high-speed mode (4,000 revolutions per minute) accelerates heat exchange by enhancing airflow intensity, significantly reducing the perceived temperature in non-air-conditioned or high-temperature environments. This tiered design balances comfort and functionality, avoiding resource waste or insufficient experience under a single mode.

3. Synergistic Optimization of Materials and Structure
The surface of the seat cushion is made of 3D breathable mesh fabric, whose porous structure reduces the skin contact area while providing a circulation channel for the fan's airflow. The interior is filled with high-elasticity memory foam, ensuring support while preventing airflow obstruction caused by a closed structure. The integrated design of the fan and the seat cushion has been optimized through fluid mechanics to ensure uniform airflow distribution across the entire contact surface, avoiding local overheating or uneven temperature.

4. Practical Application Scenarios and Effects
According to product test data, in the high-speed mode, the surface temperature of the seat cushion can drop by 3-5℃ within 10 minutes, while the low-speed mode can maintain the seat cushion humidity below 60% (relative humidity), effectively reducing the feeling of stuffiness and bacterial growth. This design is particularly suitable for office scenarios requiring long periods of sitting, such as for professionals like programmers and designers, or for use in high-temperature summer conditions or non-air-conditioned environments.
