As is known, heat is inevitably generated inside the electronic device. The heat is a factor that hinders the operation between the components of the electronic device, and also damages the circuit components during the unauthorized heating at a high temperature.

In this field, the intake fan and the exhaust fan are respectively provided in the case of the electronic device to quickly discharge the heat generated in the electronic device to ensure a stable operating state, so that the outside air having relatively low temperature is introduced into the electronic device through the intake fan. By discharging a relatively hot bet out of the case through the exhaust fan, the internal temperature of the electronic device can be maintained at an appropriate temperature at all times.

However, the intake fan and the exhaust fan are installed in the installation hole formed to communicate with the inside and the outside of the case, there is a possibility that a large amount of foreign matter, including dust, moisture, etc. in the air into the electronic device.

The foreign matter contained in the air is a factor that inhibits the operation of the electronic circuit, such as temperature, dust and water, and is also a major factor in shortening the life of the electronic device.
