Description

Heat sink unit

The present invention relates to a heat dissipating unit buckle, and more particularly to a heat dissipating unit clip which can provide an operation assembly and facilitate the stable mounting of the heat sink on the electronic component.

With the rapid development of the electronic information industry, the processing power of electronic components such as central processing units has been continuously increased, resulting in an increase in the amount of heat generated. In order to dissipate the heat, the industry usually adopts a metal with heat collecting, heat transfer and heat dissipation functions. heat sink. In order to quickly and fully dissipate its heat, the heat sink needs to be fixed to the heat-generating electronic components and kept in close contact, and a heat sink fixing device is required for this purpose.

The conventional heat sink fixing device is mainly disposed on a fixing seat by a heat sink, and then the plurality of screw members are sequentially screwed through the heat sink and the fixing seat through a hand tool (such as a screwdriver or a hexagonal plate), so that the The screw member has to fix the heat sink on the fixing seat, so that the bottom of the heat sink is closely attached to the opposite heating element (such as the central processing unit). Therefore, if the user does not have any hand tools at hand, the heat sink cannot be mounted on the fixed seat or removed from the fixed seat, resulting in poor convenience in operation and assembly. In addition, due to the different force applied by the screw lock of the manual mode, it is easy to cause the lock to be too tight to damage the heat sink itself, or the lock is too loose, which may cause the radiator to loosen.

Accordingly, in order to effectively solve the above problems, the main object of the present invention is to provide a heat dissipating unit clip which can be easily assembled and assembled and fastened.

Another object of the present invention is to provide a heat sink that can be stably attached to a motherboard without the need of a borrowing tool, and the heat sink is closely attached to at least one electronic component (or a heat source) disposed on the motherboard. Cooling unit clips.

In order to achieve the above object, the present invention provides a heat dissipating unit buckle for mounting on a motherboard for combining at least one heat source. The heat sink unit includes a heat sink, a first elastic pressing member, and a second elastic pressing member, the first and second elastic pressing members are respectively disposed on the upper side of the main board, and the first elastic pressing member corresponds to the second elastic pressing member, and the first and second The elastic pressing member is respectively provided with a first protruding block and a second protruding block opposite to the first protruding block, and the heat sink further includes a plurality of heat dissipation fins, a first fastening component and a second fastening component. The first and second fastening members are respectively disposed on opposite sides of the heat sink, and the first and second fastening members respectively correspond to the first and second convex portions. The first and second elastic pressing members are elastically deformed against the pressing or unscrewing with or without pressing against the other side of the heat sink, so that the heat sink can be Stabilizing or loosening the motherboard, so the design of the heat sink unit of the present invention is effective To facilitate assembly operation and effect are stable engagement.

The following is an actual implementation to illustrate:

Please refer to the 4th and 5th drawings, and refer to the 2A and 3B diagrams. When the user mounts the heat sink 31 on the electronic component 51 of the motherboard 5, the first and second buckles of the heat sink 31 are used. After the pieces 33 and 35 respectively correspond to the first and second bumps 21a and 21b of the first and second elastic pressing members 2a and 2b on the main board 5, the first and second buckle portions 334 and 354 are then first. The two buckle ends 3341, 3541 are placed in contact with the first and second hook portions 211a, 211b, and then the first and second fingers are passed through the finger of the user's single hand (or the fingers of both hands). The shank ends 3310 and 3510 are biased downwardly to move the first and second connecting ends 3311 and 3511 away from the corresponding first and second recessed holes 3336 and 3536. 334, 354 and the first and second bumps 21a, 21b hooked (or buckled) are displaced upward with the first and second connecting ends 3311, 3511, at this time, the first and second pressing portions 23a 23b is pulled up by the first and second bumps 21a, 21b and moved upwards away from the upper side of the motherboard 5 (Fig. 5A) until the first and second connecting ends 3311, 3511 are respectively moved. Above the first and second rotating shafts 34, 36, and the first and second handle ends 3310, 3510 respectively adjacent to the first and second bumps 21a, 21b, the first and second fastening members 33, 35 will The elastic reaction force is applied to the heat sink 31 by the elastic reaction force of the first and second pressing portions 23a and 23b, and the first and second elastic portions 24a and 24b follow the first and second pressing portions 23a. After the 23b is pulled up (or displaced upward) and elastically deformed against the bottom surface of the base 32 (Fig. 5A), the heat sink 31 can be engaged with the fixing member 2 (Fig. 5), and The center of the bottom surface of the base 32 of the heat sink 31 can be closely attached to the opposite electronic component 51.

If the heat sink 31 is to be disassembled at this time, the first and second handle ends 3310 and 3510 are biased upward by the finger of the user's single hand (or the fingers of both hands), so that the first And the two connecting ends 3311, 3511 are respectively moved downwards corresponding to the first and second recessed holes 3336, 3536, and the first and second fastening portions 334, 354 are hooked (or buckled) with the first, The two bumps 21a, 21b are gradually released as the first and second connecting ends 3311, 3511 are displaced downward, and the first and second pressing portions 23a, 23b also follow the first and second convex portions.

Therefore, the design of the heat dissipating unit clip 1 of the present invention effectively eliminates the need to fix the heat sink 31 by other hand tools (such as a screwdriver or a wrench), thereby achieving the convenience of operation and assembly, and the fastening effect, and saving. The effect of assembly time.

Referring to Figure 8, there is shown an exploded perspective view of a second preferred embodiment of the present invention. The structure and the connection relationship of the preferred embodiment are the same as those of the first preferred embodiment. Therefore, the difference between the two is that the heat dissipating unit buckle 1 further includes a fixing member 4, The fixing member 4 is formed of a metal material (such as an aluminum alloy material or a white iron material), and the fixing member 4 has an opening 43 which is opened at the center of the fixing member 4 and is bare. Empty, and the fixing member 4 is described as the following two aspects: wherein the first aspect, as shown in Figures 8, 8A, 8B, the fixing member 4 is disposed on the motherboard 5 and the first and second Between the elastic pressing members 2a, 2b, that is, the first and second elastic pressing members 2a, 2b are respectively disposed on the opposite branches 41 of the fixing member 4 via the opening 43, and the fixing member 4 The electronic component 51 on the motherboard 5 is framed, and the electronic component 51 is located in the opening 43, so that the electronic component 51 is closely attached to the center of the other side corresponding to the heat sink 3.

In the second aspect, referring to FIG. 9 , the fixing member 4 is disposed on the lower side of the motherboard 5 , and the opposite branches 41 of the fixing member 4 correspond to the first board and the second board via the motherboard 5 . The elastic pressing members 2a, 2b are sequentially threaded through the plurality of screw members 44 to pass through the two opposite portions 41 of the fixing member 4 and the first and second elastic pressing members 2a, 2b. Two fixing portions 25a, 25b.

Therefore, the fixing member 4 is disposed between the main board 5 and the first and second elastic pressing members 2a, 2b or on the lower side of the main board 5, so as to effectively enhance (or increase) the overall structural strength. effect.
