Description

Technical Field

[0001] The present invention relates to the technical field of fixing a heat sink fan of a radiator, and in particular to a fixing buckle of a fan of a radiator and an assembly structure thereof. Background Art

[0002] There are two main types of radiators used for cooling and dissipating heat on processors today: air-cooled radiators and liquid-cooled radiators. For example, as shown in Taiwan Patent Publication TW200741169A, an air-cooled radiator uses a heat pipe to connect a cooling head and a heat dissipation fin, and a heat dissipation fan is installed on one side of the heat dissipation fin. As shown in Taiwan Patent Publication TW202347085A, a liquid-cooled radiator uses a liquid-cooled heat sink connected to a liquid-cooled head, and a heat dissipation fan is installed on one side of the liquid-cooled heat sink.

[0003] When the above cooling fan is installed on the cooling fins or liquid cooling radiator, the traditional assembly structure uses multiple screws to pass through the four screw holes of the cooling fan, and then screws are screwed into the screw holes of the cooling fins or liquid cooling radiator. Another assembly structure uses a clip to fix the cooling fan, and the structural style of the clip varies, including spring clip clips and steel wire clips. The conventional steel wire clip used to fix the cooling fan, such as shown in Chinese patent publication CN101351104A and patent announcement CN209343284U, fixes a cooling fan on the cooling fins through two steel wire clips, and the steel wire clip is directly buckled on the cooling fins or liquid cooling radiator. However, this conventional steel wire clip structure design cannot fix two cooling fans on both sides of the cooling fins or liquid cooling radiator. As long as the structure of the cooling fins or liquid cooling radiator changes, the conventional steel wire clip cannot be used. Therefore, how to solve this problem is the subject that the present invention actively overcomes. Summary of the invention

[0004] The main purpose of the present invention is to provide a fan fixing clip for a radiator and its assembly structure. Through the structural design of a first clip and a second clip formed by bending a metal strip as a whole, the first clip and the second clip are hooked and locked together to quickly fix two cooling fans on two sides of a radiator.

[0005] In order to achieve the above-mentioned object, the present invention provides a fan fixing clip for a heat sink, wherein a preferred technical solution thereof includes a first clip and a second clip, wherein:

[0006] The first buckle comprises a first straight bar and two first horizontal bars formed by bending a metal bar in one piece; a latching protrusion is bent at the middle of the first straight bar, and the latching protrusion protrudes in a direction opposite to or the same as the direction of the free end of the first horizontal bar; the fixed ends of the two first horizontal bars are connected to the upper and lower ends of the first straight bar, and the free ends of the two first horizontal bars are respectively bent into a first buckle portion, and the first buckle portion extends in the direction of the first straight bar;

[0007] The second buckle comprises a second straight bar and two second horizontal bars formed by bending another metal bar in one piece; the second straight bar is parallel to the first straight bar; the fixed ends of the two second horizontal bars are respectively bent into a U-shape to form a hook portion, the hook portion is connected to the upper and lower ends of the second straight bar, and the free ends of the two second horizontal bars are respectively bent into a second buckle portion, and the second buckle portion extends toward the direction of the second straight bar; and

[0008] The first buckle portion of the first buckle and the second buckle portion of the second buckle are used to respectively embed a cooling fan, so that the first straight bar of the first buckle can be hooked by the hook portion of the second buckle, and the latching protrusion of the first buckle can be latched on the inner side of the second straight bar, so that the first straight bar of the first buckle cannot be separated from the hook portion without external force.

[0009] In order to achieve the above object, the present invention proposes a fan fixing clip assembly structure of a heat sink, wherein a preferred technical solution includes a heat sink, a first heat dissipation fan, a second heat dissipation fan, and the above-mentioned two first clips and two second clips, wherein:

[0010] The radiator has a cooling head and a heat sink fixed on the cooling head; the first heat sink fan and the second heat sink fan are close to the front and rear surfaces of the heat sink, and the first heat sink fan and the second heat sink fan respectively have a shell and an axial flow fan blade arranged in the shell; four corners of the shell are respectively provided with a screw through hole;

[0011] The two first clips are arranged on both sides of the first cooling fan, and the upper and lower first buckle parts of each of the first clips are respectively embedded in the screw through-holes of the first cooling fan, so that the two first clips are located on both sides of the heat sink; the two second clips are arranged on both sides of the second cooling fan, and the upper and lower second buckle parts of each of the second clips are respectively embedded in the screw through-holes of the second cooling fan; and

[0012] The first straight bar of each first buckle is hooked by the upper and lower hooks of each second buckle, and the latching protrusion of each first buckle is latched on the inner side of the second straight bar. The first straight bar of the first buckle cannot be separated from the hook without external force, and the latching protrusion of the first buckle cannot be separated from the inner side of the second straight bar without external force.

[0013] The present invention provides a fan fixing clip of a radiator and its assembly structure. The first clip and the second clip can be hooked together and locked with each other, so that two cooling fans (first and second cooling fans) can be fixed to the front and back sides of the heat sink of the radiator. Furthermore, the present invention can prevent the first clip from being separated from the second clip through the structure of the second clip hooking the first clip and the structural design of the locking protrusion of the first clip locking on the inner side of the second straight bar, thereby ensuring that the clips fix the two cooling fans to the front and back sides of the radiator. The first clip and the second clip of the present invention are not buckled on the radiator, so changes in the structure of the radiator will not affect the functions of the first clip and the second clip.

[0052] The technical features, structures and other functions, purposes and effects of the present invention are described in detail as follows according to the accompanying drawings:

[0053] See also Figures 1 to 4 As shown, a fan fixing buckle of a radiator of the present invention is used to fix two cooling fans 30, 30' on the front and rear surfaces of a radiator 40. Figure 5 As shown, the first preferred embodiment includes a first buckle 10 and a second buckle 20, wherein:

[0054] The first buckle 10 is formed by bending a metal bar (such as a stainless steel bar) into a first straight bar 11 and two first horizontal bars 12. A latching protrusion 13 is bent in the middle of the first straight bar 11, and the latching protrusion 13 protrudes in the opposite direction of the free end of the first horizontal bar 12. The fixed ends of the two first horizontal bars 12 are integrally connected to the upper and lower ends of the first straight bar 11, and the free ends of the two first horizontal bars 12 are respectively bent into a first buckle portion 14, and the first buckle portion 14 extends toward the direction of the first straight bar 11. The latching protrusion 13 is a square protrusion (such as a square protrusion) formed by bending the first straight bar 11. Figure 5 As shown), U-shaped ridges or semicircular ridges (as shown Figure 7 as shown) or trapezoidal ridges (as Figure 8 ), which can be locked in the second buckle 20 (as shown) when combined. Figure 6 The first buckle portion 14 is a square body, a U-shaped body or a semicircular body formed by bending the free end of the first horizontal bar 12.

[0055] The second buckle 20 is formed by bending a metal bar (such as a stainless steel bar) into a second straight bar 21 and two second horizontal bars 22. The second straight bar 21 is parallel to the first straight bar 11 when assembled, and is used to clamp the latching protrusion 13 (such as the first buckle 10) of the first buckle 10. Figure 6 The two second horizontal bars 22 are shorter or equal in length to the first horizontal bar 12. The fixed ends of the two second horizontal bars 22 are respectively bent horizontally in a U-shape to form a hook portion 23. The hook portion 23 is preferably a U-shaped hook. The hook tip of the hook portion 23 is integrally connected to the upper and lower ends of the second straight bar 21. The free ends of the two second horizontal bars 22 are respectively bent into a second buckle portion 24. The second buckle portion 24 extends toward the direction of the second straight bar 21. The second buckle portion 24 is one of a square body, a U-shaped body or a semicircular body formed by bending the free end of the second horizontal bar 22.

[0056] Through the fan fixing clip design of the above radiator, refer to Figure 1 , Figure 5 and Figure 6As shown, the first buckle portion 14 of the first buckle 10 and the second buckle portion 24 of the second buckle 20 are used to be respectively embedded (inserted) into the screw through holes 33 of a cooling fan 30, 30', and then the first straight bar 11 at one end of the first buckle 10 can be turned over or adjusted to the outside of the second straight bar 21 of the second buckle 20, and then force is applied so that the upper and lower parts of the first straight bar 11 are hooked by the hook portion 23 of the second buckle 20 (as shown in FIG. Figure 1 , Figure 4 and Figure 6 The latching protrusion 13 of the first buckle 10 can also be adjusted by applying pressure from the outside of the second straight strip 21, so that the latching protrusion 13 is changed to latch on the inside of the second straight strip 21 (as shown in FIG. Figure 1 and Figure 6 As shown). Thus, the first straight strip 11 of the first fastener 10 cannot be separated from the hook portion 23 without external force, and the latching protrusion 13 of the first fastener 10 cannot be separated from the inner side of the second straight strip 21 without external force, so as to achieve the function of fixing the two cooling fans 30, 30' on the front and rear surfaces of the heat sink 42 of the radiator 40.

[0057] See also Figures 1 to 4 As shown, based on the features of the first clip 10 and the second clip 20, the present invention further proposes a fan fixing clip assembly structure of a heat sink, wherein a preferred embodiment includes a heat sink 40, a first cooling fan 30, a second cooling fan 30', and the two first clips 10 and the two second clips 20, wherein:

[0058] The heat sink 40 has a cooling head 41 for attaching to the processor, and a heat sink 42 fixed to the cooling head 41. The first heat dissipation fan 30 and the second heat dissipation fan 30' are close to the front and rear surfaces of the heat sink 42. The first heat dissipation fan 30 and the second heat dissipation fan 30' respectively have a housing 31 and an axial flow fan blade 32 disposed in the housing 31, and the four corners of the housing 31 are respectively provided with a screw through hole 33. More specifically, the first heat dissipation fan 30 and the second heat dissipation fan 30' are of existing structures, which have two quadrilateral frames 311 located at both ends of the housing 31, and the four corners of each quadrilateral frame 311 are provided with the screw through hole 33.

[0059] Thus, the two first clips 10 are arranged on both sides of the first cooling fan 30, and the upper and lower first buckle portions 14 of each first clip 10 are respectively inserted into the screw through holes 33 of the first cooling fan 30, so that the two first clips 10 can be located on both sides of the heat sink 42. The two second clips 20 are arranged on both sides of the second cooling fan 30', and the upper and lower second buckle portions 24 of each second clip 20 are respectively inserted into the screw through holes 33 of the second cooling fan 30'.

[0060] By applying external force to flip or adjust, the first straight strip 11 of each first buckle 10 is hooked by the upper and lower hooks 23 of each second buckle 20, and the latching protrusion 13 of each first buckle 10 is adjusted to latch on the inner side of the second straight strip 21. In this way, the first straight strip 11 of the first buckle 10 cannot be separated from the hook 23 without external force, and the latching protrusion 13 of the first buckle 10 cannot be separated from the inner side of the second straight strip 21 without external force.

[0061] See also Figure 2 As shown, the radiator 40 of the present invention is preferably implemented as an integrated liquid cooling radiator, which has a cooling head 41, and the heat sink 42 is a liquid cooling radiator, which has a first liquid box 421, a second liquid box 422, a plurality of heat sink pipes 423 and a liquid pump 43. The interior of the first liquid box 421 is connected to the cooling head 41, the second liquid box 422 is located at a distance relative to the first liquid box 421, the heat sink pipe 423 is connected between the first liquid box 421 and the second liquid box 422, and the liquid pump 43 is arranged in the second liquid box 422, so that the liquid pump 43 is used to drive the liquid in the liquid cooling radiator to circulate through the cooling head 41 to cool the processor, and can transfer heat to the heat sink pipe 423, and the cold air blown by the two cooling fans 30, 30' dissipates heat.

[0062] See also Figures 9 to 13 As shown, it is the second preferred embodiment of the present invention, which also includes a first buckle 10 and a second buckle 20. Its structure is basically the same as the first preferred embodiment, except that: the latch protrusion 13 in the middle of the first straight bar 11 of the first buckle 10 is changed to protrude toward the free end of the first horizontal bar 12, and an operating protrusion 15 is bent at the first straight bar 11 between the latch protrusion 13 and the upper and lower first horizontal bars 12. The operating protrusion 15 is one of a square protrusion, a U-shaped protrusion, a semicircular protrusion or a trapezoidal protrusion formed by bending the first straight bar 11. Fig.10 and Fig.11 As shown, the operating protrusion 15 protrudes in a direction opposite to the free end direction of the first horizontal bar 12, and protrudes at a 45 degree angle with the first horizontal bar 12; or as Fig.12 and Fig.13 As shown, the operating protrusion 15 and the first horizontal bar 12 protrude at an angle of 90 degrees.

[0063] For reference Fig.10 and Fig.12As shown, when the first buckle 10 and the second buckle 20 are combined, the user can hold the operating protrusion 15 to apply force, so that the hook portion 23 of the second buckle 20 can be hooked on the first straight bar 11, but the latching protrusion 13 is opposite to the first preferred embodiment, so that the latching protrusion 13 is reversely latched on the inner side of the second straight bar 21 of the second buckle 20. At the same time, the operating protrusion 15 extends at a 45-degree or 90-degree angle to the free end of the second horizontal bar 22 of the second buckle 20, so as to facilitate the operation of the first buckle 10 and the second buckle 20 to engage or separate.

[0064] In summary, the fan fixing buckle and assembly structure of the radiator of the present invention are indeed practical and creative, and the application of its technical means is undoubtedly novel, and the effect is indeed consistent with the design purpose, which is considered to be a reasonable progress. For this reason, I have filed an invention patent application in accordance with the law, but I sincerely ask the Office to examine it in detail and grant the patent. I will be grateful.
