Computer main case capable of improving dustproof effect

Abstract

The invention discloses a computer main case capable of improving dustproof effect. The computer main case capable of improving dustproof effect comprises a case, wherein an upper end of the case is opening, a rectangular cover board is arranged over the case, four first threaded rods are respectively fixed on four top ends at the upper end of the case, the upper ends of the four first threaded rods respectively pass through four round fixing holes on the cover board, the upper ends of the four first threaded rods are respectively in threaded connection with the four first nuts, the four firstnuts are all located above the cover board, four support devices are evenly fixed at the lower surface of the case, a dust filtering device prevents dust from entering into the case, when temperaturein the case is always too high, a user makes a control value be conducted, compressed air in a compressed air tank enters into the case via the control valve, the compressed air expands and absorbs heat, thus, temperature in the case is reduced, a draught fan blows air to realize heat dissipation and the compressed air in the compressed air tank expands and absorbs heat, thus, heat dissipation effect of the case is guaranteed.

Description

technical field [0001] The invention relates to the technical field of chassis, in particular to a main computer chassis with improved dust-proof effect. Background technique [0002] As a part of computer accessories, the main function of the chassis is to place and fix various computer accessories, and play a supporting and protective role. In addition, the computer chassis has an important role in shielding electromagnetic radiation. In order to increase the heat dissipation efficiency of computer components, traditional chassis often have cooling holes on the side of the chassis, which is passive cooling and has low heat dissipation efficiency. However, dust enters the box through the cooling holes and affects computer components, requiring frequent cleaning. ; Dust enters the box, and a large amount of dust will stick to the fan blades of the cooling fan, which needs to be cleaned frequently. Contents of the invention [0003] The technical problem to be solved by th...
