2. Description of the Related Art In recent years, in electronic devices such as servers, for example, high performance and miniaturization (space saving) have been remarkable. As electronic devices have become smaller, the degree of freedom in installation has increased.

[0003]

In the above-mentioned prior art, it is necessary to take sufficient measures for heat dissipation as the size of electronic equipment is reduced. This is because, in the case of an electronic device having a large volume, natural heat radiation is sufficiently performed because the surface area of the housing is large, but it is difficult to perform sufficient heat radiation with a small electronic device.

[0004] For example, it is conceivable to increase the size of the vents (intake and exhaust) for sufficient heat radiation. However, in such a case, there is a possibility that foreign matter may enter the electronic device. Therefore, the size of the ventilation hole cannot be made larger than necessary. Also, as miniaturization progresses,
Since the restrictions on the installation location of the electronic device and the like are reduced, a plurality of electronic devices can be arranged side by side on a shelf, for example. However, in such a case, there is a problem that the vent of the electronic device is blocked, and the heat radiation efficiency is further reduced.

[0005] Therefore, an object to be solved by the present invention is to provide an electronic device having a high heat dissipation efficiency, particularly in a miniaturized electronic device, in which a sufficient ventilation hole can be secured regardless of how the electronic device is installed. It is to provide a housing.
