Description

server

The present invention relates to a server, and more particularly to a server having an air hood.

As the number of electronic components in the server increases, the thermal energy generated by the electronic components also increases dramatically. Therefore, it is necessary to increase the number of fans in the fan module in the server. However, when a single fan in the fan module fails and needs to be replaced, it is necessary to pull the fan module out of the server's main chassis. However, once the fan module is pulled out of the main chassis, the fan module and the main chassis must have a gap, which causes the airflow to flow back and the airflow cannot flow into the mainframe of the server, thereby causing the electronic components in the main chassis. Component heat dissipation is abnormal and affects the normal operation of electronic components.

Therefore, it is necessary to solve the problem that the fan module causes airflow backflow due to the interval generated when the autonomous chassis is pulled out without affecting the normal operation of the electronic component.

The invention provides a server for solving the problem of lowering the heat dissipation efficiency caused by the return flow of the air when the fan module needs to be replaced.

A server according to an embodiment of the invention includes a main box and a wind Fan module and a windshield. The main chassis has a top plate and a bottom plate, and a first side plate and a second side plate. The first side plate and the second side plate are interposed between the top plate and the bottom plate, and the top plate, the bottom plate, the first side plate and the second side plate are formed. A space for accommodation. The fan module can be disposed in the accommodating space. The fan module has a storage position stored in the main chassis, and an extraction position in which the autonomous chassis is drawn out to maintain a gap with the main chassis. The air hood is movably disposed in the main chassis. When the fan module is displaced from the storage position to the extraction position, the air hood is displaced from the main chassis to the outside of the main chassis to shield the gap between the fan module and the main chassis.

According to the server disclosed in the present invention, the fan module is movably disposed in the accommodating space of the main chassis, and the fan module is self-contained by the presence of the air hood that is movably disposed in the main chassis. When the storage position is displaced to the extracted position, the air hood can be displaced from the main box to the outside of the main box by the linkage of the fan module, thereby shielding the gap between the fan module and the main box when the fan needs to be replaced. In this way, the shielding of the air hood can greatly reduce the chance of airflow flowing out of the gap between the main box and the fan module, thereby increasing the flow of air into the main box and achieving good heat dissipation of the electronic components in the server. .
