According to the official introduction of the Tigo9, its wireless charging module has a built-in cooling system, which can effectively reduce the heat generated during charging, ensuring charging safety and charging efficiency. At the same time, the rear of the body of the Tigo9 is also designed with a number of heat dissipation holes, which can accelerate the heat dissipation. These heat dissipation holes can not only provide ventilation and heat dissipation for the wireless charging module, but also provide good heat dissipation effect for the entire mobile phone, ensuring the stability and service life of the mobile phone. Therefore, it can be considered that the wireless charging heat dissipation hole of Tigo9 has cold air, which can effectively cool down.
According to the information I understand, the Tigo9 wireless charging heat dissipation hole is designed for heat dissipation, but there will be no cold wind blowing out. The design of the heat dissipation hole is mainly to improve the heat dissipation effect during wireless charging and prevent overheating from causing damage to the equipment. Usually, the heat dissipation hole will dissipate heat through natural convection or the built-in radiator, rather than by blowing out cold air. Therefore, the tiger 9 wireless charging heat dissipation hole will not have cold wind blowing out.
