Server

A server, comprising:

• a chassis, a backplane with a ventilation opening, a rear board, a first air ducting apparatus, a third air ducting apparatus, and a first fan module, wherein:
• the backplane, the rear board, the first air ducting apparatus, and the first fan module are located in the chassis;
• the backplane is located in the middle of the chassis, and the rear board is connected to a rear side of the backplane in a pluggable manner;
• the first fan module is disposed side by side with the rear board along a horizontal direction, and is connected to the rear side of the backplane in a pluggable manner;
• the first fan module comprises:
• a fan and a second air ducting apparatus;
• and through rotation of the fan and cooperation between the second air ducting apparatus and the first air ducting apparatus, air that enters from the front of the backplane through the ventilation opening on the backplane turns towards the rear board and then flows out of the chassis after passing through the first fan module, so as to dissipate heat of a component on the rear board;
• and
• the third air ducting apparatus is disposed inside the chassis and located on one side of the first fan module, the third air ducting apparatus comprising an elastic apparatus to cause the third air ducting apparatus to spring up after the first fan module is removed from the chassis, the third air ducting apparatus being positioned, after the first fan module is removed, to direct air that enters from the front of the backplane to turn towards the rear board, so as to dissipate the heat of the component on the rear board.
