Description

Filter magnetic attachment device

technical field

The utility model relates to a filter screen structure, in particular to a filter screen magnetic attachment device which is convenient for disassembly and installation.

Background technique

Generally, the cooling device of the mainframe computer blows the air through the rotation of the fan, causing the air flow to take away the heat generated by the mainframe computer, so that the mainframe computer can work normally, but the air contains a lot of dust and impurities that are not easy to see with the naked eye. There are many conductive substances. If such substances accumulate, it will easily cause the computer host to malfunction. Therefore, a filter is usually installed on the computer host, so that the air that is going to enter the computer host will first filter out dust and impurities through the filter to avoid air pollution. Dust and impurities in the computer accumulate inside the mainframe of the computer, affecting the normal use of the computer.
