Abstract
Nowadays many electronic devices, such as LCD projector, computer servers, and air fresher etc. require reliable air cooling system to reduce the risk of electronics damage caused by overheating. The present invention disclosed an apparatus integrated with air flow sensor as an alarm apparatus for air flow clog detection. The major prior approach for air flow circulation failure detection is based on an indirect measurement method of temperature monitoring on surrounding environments, which method is suffering from the slow response and poor identification of real-time situation. The present invention will demonstrate the advantages by directly monitoring air flow over by indirectly monitoring the surrounding temperature as for the purpose of preventing air flow path clog.
