Description

Technical Field

[0001] This utility model relates to the field of computer heat dissipation mechanisms, and in particular to a computer heat dissipation mechanism with a detachable fan. Background Technology

[0002] Existing computer fans generally include a housing and fan blades located in its pivot space, thereby enabling the guidance and stable output of fluid.

[0003] However, existing heat dissipation towers are generally rectangular in shape, although other shapes are not excluded. In actual manufacturing, rectangular structures can reduce material waste, while angular structures can also provide the intended aesthetics of the heat dissipation tower.

[0004] In existing designs, a heatsink typically includes a heat pipe, a heatsink that encloses the heat pipe, and a heatsink plate located at the condenser end of the heat pipe (the heatsink plate extends outward on both sides of the heatsink and is equipped with screws, and a computer fan is usually installed above the screws). When the heatsink plate needs to be installed on the CPU, the casing usually needs to be disassembled to avoid interference when tightening the screws to fix it to both sides of the CPU.

[0005] However, in actual installation, it was found that when the internal space of the chassis is small, the installation of the fan housing is more troublesome, that is, it requires alignment and stable fixation, which affects the user experience. Utility Model Content

[0006] The main purpose of this invention is to propose a computer cooling mechanism with a detachable fan, which aims to improve the existing fan structure by using a modular design for the bracket and fan blades to create clearance space around the fan blades, reducing or avoiding interference when the screw is turned, thus facilitating installation. Once the screw is turned to a stable position, the outer frame can be installed on the heat sink or bracket. Its structure is simple and stable.

[0007] To achieve the above objectives, this utility model proposes a computer cooling mechanism with a detachable fan, comprising:

[0008] A heat dissipation assembly, comprising a heat dissipation tower composed of several heat dissipation fins;

[0009] The support is flat and can be detachably installed on the wall of the heat dissipation tower. The support is pivotally mounted with fan blades.

[0010] The outer frame is detachably installed on the heat dissipation component or bracket. The outer frame is provided with an air vent, which is arranged opposite to the fan blade.

[0011] The bracket and fan blades are designed as a modular unit, creating clearance space around the fan blades (meaning the bracket can be installed on the heat sink without screwing in the screws), reducing or avoiding interference when screwing in the screws, thus facilitating installation. Once the screws are screwed in place, the outer frame can be installed on the heat sink or bracket. The structure is simple and stable. Attached Figure Description

[0029] like Figures 1 to 5 As shown, a computer cooling mechanism with a detachable fan includes:

[0030] The heat dissipation component is a heat dissipation tower composed of several heat dissipation fins (and of course, heat pipes, heat dissipation plates, and other structures).

[0031] Support 2, which is flat and can be detachably installed on the wall of heat dissipation tower 1, and fan blades 3 are pivotally mounted on support 2;

[0032] The outer frame 4 is detachably installed on the heat dissipation assembly and encloses the fan blade 3 therein. The outer frame 4 can partially enclose the heat dissipation tower 1. The outer frame 4 is provided with an air vent 40, which is arranged opposite to the fan blade 3.

[0033] The bracket and fan blades are designed as a modular unit, creating clearance space around the fan blades to reduce or avoid interference when the screw is tightened, thus facilitating installation. Once the screw is tightened to a stable position, the outer frame can be installed on the heat sink or bracket. The structure is simple and stable.

[0034] In the actual design, the existing fan frame 4 structure is improved, which makes the structure of the fan blade 3 simpler and thus has a larger flow area, which can achieve heat dissipation of the entire heat tower 1 and reduce the fluid blind zone.

[0035] At the same time, the outer frame 4 not only directs the fluid in a predetermined direction but also enhances the overall aesthetics of the heat dissipation tower 1.

[0036] For example, the heat dissipation tower 1 can be configured as a light guide structure or have a predetermined pattern or logo set according to actual needs, thereby meeting the needs of different buyers while satisfying the performance of the heat dissipation mechanism, and thus reducing production costs.

[0037] Specifically, the bracket 2 is located on the side or top wall of the heat dissipation assembly, and the corresponding outer frame 4 is also installed above or to the side of the heat dissipation tower 1, thereby achieving the coverage of the heat dissipation tower 1.

[0038] In this embodiment of the utility model, the outer frame 4 includes a front panel 41 and a surrounding panel 42 extending rearward from the front panel 41, and the air vent 40 is located at the position of the front panel 41.

[0039] Specifically, the lower enclosure 42 is provided with a clearance groove 44, and the rear end of the enclosure 42 is a through channel 43, thereby achieving clearance of the heat pipe assembly. Of course, the through channel 43 can also be set in the lower wall position, wherein the through channel 43 is preferably connected to the air vent 40.

[0040] In this embodiment of the utility model, the outer frame 4 is a light guide structure and has a predetermined pattern or logo, thereby improving the overall aesthetics of the heat dissipation mechanism.

[0041] Specifically, the side panels 42 on both sides have buckles that abut against the rear wall of the heat sink 1, thereby enabling the installation of the outer frame 4.

[0042] In this embodiment of the utility model, the front wall of the bracket 2 is provided with a plurality of first magnetic elements 51, and the inner side of the front plate 41 is provided with a second magnetic element 52 that cooperates with the first magnetic elements 51, thereby realizing the quick installation of the outer frame 4.

[0043] Of course, in specific embodiments, both snap-fit ​​and / or magnetic components can be used together.

[0044] Specifically, the bracket 2 is provided with buckles 6 on both sides. One end of the buckle 6 is connected to the bracket 2, and the other end is locked to the side of the heat dissipation tower 1, thereby realizing the installation of the bracket 2.

[0045] The corresponding outer frame 4 can also cover the pull tab 6 and the card slot 61, thereby improving the overall aesthetics of the heat dissipation mechanism.

[0046] The pull tab 6 can be made of wire, making installation easier.

[0047] In this embodiment of the utility model, the heat dissipation tower 1 has slots 61 extending through its height on both sides, and the other end of the pull buckle 6 has a locking part 62 that cooperates with the slots 61.

[0048] Specifically, the bracket 2 includes a main body 20 and support arms 21 extending from the main body 20 in four directions. The support arms are provided with through holes 63 for connecting with the buckle 6 to reduce its thickness. The support arms can reduce the area they block.
