Description

server

The present invention relates to a server, and more particularly to a server for preventing backflow of air.

Generally, the electronic device includes a desktop computer, a notebook computer, a tablet computer, a personal digital assistant (PDA) or a server, and each of the electronic devices has a suitable safe operating temperature upper limit value. When the existing temperature of the electronic device exceeds the upper limit of the safe working temperature, the electronic device may cause irreversible damage, such as damage to the machine and internal components, and even more serious, even a fire. Therefore, each electronic device is equipped with a heat dissipating device, so that the electronic device can operate in an environment below the upper limit of the safe working temperature, thereby extending the working life of the electronic device.

In terms of servers, in order to have excellent performance of the server, multiple sets of electronic circuit devices are often arranged inside the server. However, the more electronic devices that are inserted into the narrow space of the server, the higher the temperature produced by the server during operation. Therefore, one side of the server usually has a plurality of sets of cooling fans arranged side by side, so that the internal heat energy of the server can be discharged out of the server through the cooling fan to maintain the servo operating in a safe working temperature environment. At this time, if all the cooling fans are damaged, it is reasonable to stop the server to prevent the server from being shut down due to the high temperature of the electronic circuit device. However, if only part of the cooling fan is damaged, the heat generated by the remaining fan can be taken away from the server by the wind generated by the remaining fan operation. However, due to the damage of the fan, the vent of the damaged fan is an open space and communicates with the inside of the casing and the outside of the casing, because the gas will take the shortest path, and the path of the gas flowing from the vent of the damaged fan to the vent of the running fan The path from the suction port to the vent of the running fan is shorter, so the cold air outside the server will enter the server through the vent of the damaged fan, and the running fan directly draws the outside cold air away from the servo. Outside the device. As a result, the outside cold air does not pass through the high temperature electronic circuit device. Therefore, even if some of the cooling fans continue to operate, the server will not cool down, which will also cause the server to generate a thermal crash. It is one of the first problems that designers should solve when designing a fan that does not allow outside cold air to enter directly from the vent of the damaged fan.

In view of the above problems, the present invention relates to a server for solving the problem that the outer boundary cold air of the prior art directly enters from the vent of the damaging fan.

A server according to an embodiment of the invention includes a casing, a first air extracting device, a first rotating frame and at least one first blocking piece. Wherein, the casing has at least one suction port and a first exhaust port. The first air suction device is disposed inside the casing and located at the first exhaust port. The first rotating frame is disposed outside the first exhaust port of the casing so as to be rotatable relative to the casing, and the rotating shaft of the first rotating frame faces the same direction as the first exhaust port, and the first rotating frame has a first The attaching member, when the casing is inclined, the weight of the first attaching member causes the first attaching member to pull the first rotating frame to rotate relative to the casing. The first flap is pivotally connected to the first rotating frame and located at the first exhaust port. When the first air extracting device is operated, a gas is generated by the air inlet and discharged by the first air outlet. The gas generated by the air device blows the first flap to pivot the first flap relative to the casing to expose the first exhaust port, and when the first air suction device stops operating, the first flap is stopped The gas is pushed and pulled by gravity to pivot relative to the casing to cover the first exhaust port.

According to the server disclosed in the above embodiment, the first flap is pivoted on the casing located at the first exhaust port, and when gas flows through the first exhaust port, the first flap is The gas blows and resists the effects of gravity, thereby pivoting relative to the casing to expose the first exhaust port. When the air suction device stops running or is damaged, the gas stops flowing through the first exhaust port, so that the first flap is pivoted relative to the casing to cover the first exhaust port by being stopped by the gas and being pulled by gravity. . At this time, the first flap can prevent outside cold air from flowing into the server from the first exhaust port, so that the outside cold air can flow from the air inlet, and the cold air passes through the electronic circuit device and exchanges heat to become hot air, hot air. The server is then discharged from the second exhaust port.

Wherein, when the first rotating frame 500 rotates relative to the first frame 161, the rotating shaft of the first rotating frame 500 and the first exhaust port 120 face in the same direction, so that the first rotating frame 500 is maintained in the same plane, and the first vent The shape of the 520 remains in the same position. That is, the first rotating frame 500 is rotated about the centroid of the first vent 520 and rotates relative to the first frame 160. The second rotating frame 600 also has a plurality of second protruding portions 630 and is disposed on the second sliding slot 171 of the second frame 170 in the same rotational relationship as the first rotating frame 500.

The effect is relative to the housing 100 pivoting to expose the first exhaust port 120 and the second exhaust port 130. Then, if the first air extracting device 300 is damaged and the gas flow path a is changed, the first air extracting device 300 stops the guiding gas from being discharged from the first exhaust port 120, and the gas is guided by the second air extracting device 400. The second exhaust port 130 is discharged. Therefore, the first flap 700 pivots relative to the casing 10 to cover the first exhaust port 120 by being stopped by the gas and being pulled by gravity. At this time, since the first exhaust port 120 is closed by the first flap 700 to prevent gas from flowing in from the first exhaust port 120, all of the gas can flow in through the intake port 110, and the electronic circuit is passed along the gas flow path a. After the device 200, it is discharged from the second exhaust port 130.
