COOLING SYSTEM, METHOD FOR DETECTING CLOGGING OF AIR FILTER AND SIGNAL TRANSMISSION APPARATUS |
摘要 |
A cooling system includes: a cooling fan configured to take in air through an air filter and to send the air to one or more electronic components; one or more first temperature detectors configured to detect temperatures of the one or more electronic components; a revolution controller configured to control a number of revolutions of the cooling fan on basis of the temperatures detected by the one or more first temperature detectors; and a clogging detector configured to, when the number of revolutions of the cooling fan controlled by the revolution controller is greater than a reference number of revolutions of the cooling fan that makes the temperature of the one or more electronic components less than upper-limit temperatures of the one or more electronic components, detect a clogging condition for the air filter. |
