Piezoelectric radiator
Piezoelectric radiator uses the principle of inverse piezoelectric effect of piezoelectric ceramics to give a certain voltage to the piezoelectric vibrator, so that the piezoelectric vibrator produces deformation. Through the deformation of the vibrator, the deformation of the cooling cavity is driven, so as to form air pressure. After the air pressure is generated, the flow of gas in the cooling cavity will be increased, so as to achieve the purpose of heat dissipation.
The main features are as follows:
1) Small size;
2) Light weight;
3) High air pressure;
4) Easy to integrate and carry;
5) Strong anti-interference ability.
Size: 20 * 20 * 1.85mm, light weight: ≤ 2.0g
Application: mainly used in electronic information system components such as heat sink.
