Description

TECHNICAL FIELD

[0001] The utility model relates to the relevant technical field of case fan, especially a fan system easy to disassemble and assemble. BACKGROUND

[0002] It is known that a computer system, including servers, network switches, desktop computers, industrial computers, game consoles, etc., must be equipped with at least one heat dissipation device to assist the heat source (such as electronic chips or electronic modules) inside the case in heat dissipation. Taking the CPU as an example, the heat dissipation device usually includes a heat-conducting block, a heat sink including a plurality of fins and a base, and a CPU fan. When working normally, the heat-conducting block conducts the heat generated by the heat source to the base of the heat sink, and then exchanges heat with the air through the plurality of fins, thereby dissipating (discharging) heat to the air. And the CPU fan operates to make the hot air flow, increasing the heat dissipation speed.

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

[0004] In practice, the same case may be applied to the manufacture of computer systems of multiple different specifications, and two computer systems of different specifications must have different numbers or types of electronic chips and / or electronic modules, so that two computer systems of different specifications will include different numbers of case fans. In this case, since the position of the fixing piece (or fixing structure) in the case is fixed and cannot be changed or adjusted, the internal space of the case lacks flexible use flexibility.

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

Particularly, the containing unit has N abutting structures, and the fixed and pulling-out unit has a first abutting structure, a second abutting structure and a stop structure. When the mounting rack is arranged in the containing unit, the first abutting structure abuts against the abutting structure, and the stop structure abuts against the stop column of the side edge of the mounting rack, thereby fixing the mounting rack without using any locking screw (column). Moreover, conversely, after the fixed and pulling-out unit is rotated by an angle, the abutting structure at the bottom of the fixed and pulling-out unit abuts against the outer surface of the side plate, thereby forming a reaction force to the fixed and pulling-out unit, so that the fixed and pulling-out unit can pull out the mounting rack from the first opening.

In short, the fixing structure includes the first fixing plate 11P1, the second fixing plate 11P2, the third fixing plate 11P3, and the fourth fixing plate 11P4.

[0184] It should be understood that the fan 12 typically has multiple wires, and these multiple wires are connected to a first electrical connector 15. Therefore, the mounting bracket 11 is further designed to include a cable management structure. Specifically, the mounting bracket 11 also includes a second connecting plate 115 and a support plate 116, wherein the second connecting plate 115 is connected to the second side of the second top plate 113 and has a second notch 1151. Furthermore, the support plate 116 is connected to the second top plate 113 via at least one connector (e.g., a spacer) and is located below the first notch 1131. In this design, the support plate 116, the notch 1131, and the second connecting plate 115 serve as the cable management structure, and the support plate 116 also supports the first electrical connector 15 such that the first electrical connector 15 is located within the second notch 1151.
