A rack server center includes servers, an air conditioning system for bringing cooling air to the rack server, and an air exhaust system located outside the rack server. The air exhaust system includes an exhaust fan, branch pipes, controlling valves, and a main pipe. Each branch pipe is connected with a corresponding server via a corresponding controlling valve. The branch pipes are connected with an inlet of the exhaust fan. The main pipe is connected with an outlet of the exhaust fan. The exhaust fan is configured for exhausting heated air generated by the servers out of the rack server via the branch pipes. Each server is configured for controlling the amount of the heated air entering a corresponding branch pipe by controlling the controlling valve connected with the corresponding branch pipe. |
