Description

TECHNICAL FIELD

[0001] The utility model relates to a heat dissipation mechanism related technical field, especially a fan system easy to disassemble and assemble. BACKGROUND

[0002] It is known that a computer system (Computer system) includes a server, a network switch, a desktop computer, an industrial computer, a game console, etc., and at least one heat dissipation device is necessarily equipped to assist the heat source (such as an electronic wafer or an electronic module) inside the casing to dissipate heat. Taking a CPU as an example, the heat dissipation device usually includes a heat conduction block, a heat sink including a plurality of fins and a base, and a CPU fan. When working normally, the heat conduction block conducts the heat generated by the heat source to the base of the heat sink, and then exchanges heat with air through the plurality of fins, thereby dissipating (discharging) heat to the air. And the CPU fan operates to flow hot air, increasing the heat dissipation speed.

[0003] In addition, a plurality of casing fans are also provided in the casing of the computer system to flow hot air out of the casing. Therefore, during the development stage of the computer system, mechanism engineers must set up corresponding fixing mechanisms in the casing according to a predetermined number of the casing fans. For example, a corresponding number of fixing pieces (or fixing structures) are set up in the casing, and each fixing piece has at least one screw hole.

[0004] In practice, the same casing may be applied to the manufacture of computer systems of multiple different specifications, and two computer systems of different specifications necessarily have different numbers or types of electronic wafers and / or electronic modules, so that two computer systems of different specifications will include different numbers of casing fans. In this case, since the positions of the fixing pieces (or fixing structures) in the casing are fixed and cannot be changed or adjusted, the internal space of the casing lacks flexible use flexibility.

[0005] In summary, the existing casing fan configuration method has practical application defects. Therefore, the inventors of the utility model have made great efforts to research and invent, and finally developed the utility model of a fan system easy to disassemble and assemble.
