Backflow prevention device and server system using the same
A backflow prevention device includes at least one channeled body and at least one moving part. The at least one channeled body includes at least one first opening and at least one second opening. Each of the at least one channeled body gradually enlarges from each of the at least one first opening to each of the at least one second opening. Each of the at least one moving part is movably disposed in each of the at least one channeled body. A size of the moving part is less than a size of the second opening. When an airflow back flows from the second opening to the first opening, the airflow drives the moving part to enable the moving part to block the first opening. A server system is also disclosed.
