[0002] The computer room distribution box is a device specially used to provide power to data centers, server rooms, etc. It is usually composed of power supplies, switches and sockets to meet the power needs of electronic equipment. The main purpose of the computer room distribution box is to ensure the stable power supply required for the normal operation of equipment and systems.

[0003] When the distribution box in the computer room is in use, the internal equipment will generate heat, so the inside of the distribution box needs to be cooled. During use, the existing heat dissipation device usually dissipates heat for the distribution box through heat dissipation holes in conjunction with a heat dissipation fan. However, the heat dissipation fan is usually fixedly installed inside the distribution box, and the heat dissipation position is relatively fixed, which can easily lead to the problem of high local temperature of the distribution box. In addition, dust will follow the cooling air into the distribution box during heat dissipation. The dust will not only cause the heat dissipation holes to be blocked, but also easily cause equipment short circuit damage.
