Description

  The present invention relates to a rack for electronic devices in which a plurality of electronic devices such as computers used as servers can be mounted, and in particular, it is excellent in space efficiency, and heat dissipation efficiency of each electronic device mounted close to the rack. The present invention relates to a rack for electronic equipment that does not adversely affect the equipment.

  In recent years, for example, in a computer such as a server, there has been a significant demand for downsizing as well as higher performance. In other words, the downsizing of computers contributes to space saving when a plurality of computers are arranged side by side, and has the advantage of increasing the degree of freedom of installation, and is an important factor in model selection. .

  On the other hand, when the computer is downsized, it is important to take measures against heat radiation in the computer casing. In other words, downsizing increases the obstacles to the air flow in the computer casing, so it is not possible to reduce the size of the server with a structure that cannot guarantee heat dissipation in the casing, especially in a server whose operation reliability is the first. .

Therefore, no matter how the electronic device such as a computer is installed, a casing of the electronic device is known in which a sufficient intake port and exhaust port can be secured and the internal heat dissipation efficiency is improved ( For example, see Patent Document 1).

  According to the technique described in Patent Document 1, the casing of the electronic device is a double structure composed of a main body of the casing and a cover that covers the main body. Etc. are mounted. A substantially circular air inlet for attaching a fan for cooling the inside of the main body is formed on one side of the main body, and a plurality of slit-shaped openings are provided on the other side opposite to the side. Side-by-side exhaust ports are formed.

  In addition, an intake port and an exhaust port are also formed in the upper cover and the lower cover constituting the cover. Since the outer shape of the cover is larger than the outer shape of the main body, when the main body is covered with the cover, openings are formed between the four corners of the cover and the main body. And this opening part also functions as an inlet port and an exhaust port.

  Furthermore, U-shaped leg portions are attached to the four portions of the cover, respectively. These four legs fix the upper and lower covers of the cover, but the four legs will block the air intake and exhaust of the cover no matter how the electronic device is installed. It is supposed not to be. Therefore, sufficient air intake and exhaust properties are always ensured, and the heat in the main body is efficiently radiated.

  As described above, according to the technique described in Patent Document 1, excellent heat dissipation efficiency can be obtained even if the housing of the electronic device is downsized. However, the technique described in Patent Document 1 is not necessarily sufficient in space efficiency when a plurality of electronic devices are arranged side by side.

  That is, the air intake and exhaust performance in the main body of the electronic device casing are ensured by the cover intake and exhaust openings and the four leg portions that prevent the cover intake and exhaust openings from being blocked. ing. For this reason, when a plurality of electronic devices are arranged side by side, an extra space is required by the width of the cover and the leg of adjacent electronic devices.
