Description

Technical Field

[0001] The utility model relates to the technical field of desktop hosts, in particular to a desktop host rapid heat dissipation structure. Background Art

[0002] The chassis generally includes an outer shell, a bracket, various switches and indicator lights on the panel, etc. As a part of computer accessories, the chassis mainly plays the role of placing and fixing various computer accessories, and plays a supporting and protective role.

[0003] During the use of the computer, the processor and graphics card on the motherboard have always been components that generate relatively large amounts of heat. Especially when using the computer for entertainment activities such as playing games and watching videos, the heat generated by the graphics card will be significantly higher than usual. If the graphics card is not cooled in time, it may cause the graphics card or the computer motherboard to burn out. The cooling fans of the current host chassis are mostly set in fixed positions during use, which will result in poor cooling effects depending on the installation position. For this reason, we propose a fast cooling structure for desktop hosts. Utility Model Content
