High-pressure and ultra-thin unit
As the design of modern electronics becomes increasingly smaller and higher performance, the heat generation density inside these devices continues to grow. Having an effective heat control method is becoming a critical issue. Forced air cooling is now a necessity, even for classes of devices where natural cooling was once considered sufficient.
Electronic products with large power consumption such as computers and stationary audio-visual systems commonly have either a heat dissipation unit, for example a heat sink or heat pipe, or an air-cooling unit like a motor fan (DC fan). However, there is a growing need for heat control for much smaller products where these cooling units cannot possibly be installed.
The most important feature of our microblower is its piezoelectric ceramic based drive system that allows for an extremely compact and thin unit. Using ultrasonic vibration of the piezoelectric ceramic material, the blower functions as an air pump discharging high pressure air from the unit.
While the microblower is much smaller than common air-cooling devices, with dimensions of 20 mm by 20 mm and a height of 1.85 mm (excluding the nozzle), it is capable of significant air discharges: 1,900 Pa (maximum static pressure at 15V p-p) and 1 liter per minute (at 15 V p-p and under 100 Pa back pressure). The microblower also offers lower power consumption than more common air-cooling devices, due to it ceramic based drive system.
