Description

Technical Field

[0001] This utility model relates to the field of heat dissipation equipment technology, and more specifically, to a snap-fit ​​splicing cold-forged heat sink. Background Technology

[0002] As electronic devices and mechanical power equipment continue to develop towards higher performance, the heat generated during their operation increases dramatically, and the performance requirements for heat dissipation equipment become increasingly stringent. Heat sinks are a common type of heat dissipation equipment. There are many types of heat sinks, and finned heat sinks are a common one. They are formed by inserting and installing heat dissipation fins and heat dissipation base plates to form a whole.

[0003] In existing plug-in type heat sinks, when the heat dissipation fins and heat dissipation base plate are installed by plugging them together, the heat dissipation fins are usually inserted vertically into the pre-set rectangular slots on the top of the heat dissipation base plate to complete the assembly. Although this method can achieve the assembly of the two, the contact area between the heat dissipation fins and the heat dissipation base plate is limited, which seriously restricts the heat conduction effect and thus reduces the overall heat dissipation performance. In view of this, we propose a plug-in splicing cold forged heat sink. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a snap-fit ​​splicing cold-forged heat sink to solve the technical problem of poor heat conduction between the heat sink fins and the heat sink substrate in the current plug-in heat sink.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a snap-fit ​​splicing cold-forged heat sink, including a heat sink base plate, a plurality of equidistant heat sink fins arranged at the bottom of the heat sink base plate, a plurality of first dovetail slots equidistantly opened at the top of the heat sink base plate, and the first dovetail slots are open at both ends, a second dovetail insert is arranged in the center of the bottom of the first dovetail slot, the second dovetail insert is arranged with positioning structures at both ends, the first dovetail insert is arranged at the bottom of the heat sink fins, the second dovetail slot is arranged in the center of the bottom of the first dovetail insert, the first dovetail insert is inserted into the first dovetail slot, and the second dovetail insert is inserted into the second dovetail slot;

[0006] The second dovetail insert includes a dovetail strip and a dovetail end. The dovetail end is symmetrically arranged at both ends of the dovetail strip. The outer end of the dovetail end is narrow and the inner end is wide. The cross-sectional dimension of the inner end of the dovetail end is the same as the cross-sectional dimension of the dovetail strip. The top and bottom of the dovetail end are flush with the top and bottom of the dovetail strip. The two sides of the dovetail end are arranged in a V-shape. The cross-sectional dimension of the second dovetail slot is the same as the cross-sectional dimension of the outer end of the dovetail end.

[0007] Preferably, the dovetail end is located outside the first dovetail slot, the second dovetail insert has slots at both ends, the top of the slots is open, and the positioning structure is arranged inside the slots.

[0008] Preferably, the positioning structure includes a spring and a positioning block, the positioning block is slidably arranged in the slot, the spring is arranged at the bottom of the slot, and the top of the spring is connected to the bottom of the positioning block.

[0009] Preferably, the positioning block is L-shaped, and an insert is arranged on the side of the top of the positioning block facing the dovetail strip. Insert holes are opened at both ends of the bottom of the second dovetail slot, and the insert holes correspond to the insert blocks.

[0010] Preferably, symmetrical sliding grooves are provided on both sides of the slot, and protrusions are symmetrically arranged on both sides of the positioning block, with the protrusions located inside the sliding grooves.

[0011] Preferably, a rectangular rod is movably arranged on the side of the positioning block facing away from the insertion block, and a fixing plate is horizontally arranged at the outer end of the rectangular rod. The two ends of the fixing plate facing the positioning block are symmetrically arranged with protrusions. The two ends of the second dovetail insert are provided with positioning grooves corresponding to the protrusions, and the positioning grooves are connected to the groove openings.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model designs several sets of equidistant first dovetail slots on the heat dissipation substrate. A second dovetail insert is arranged at the bottom of each first dovetail slot. A first dovetail insert is also arranged at the bottom of the heat dissipation fins, with a second dovetail slot at its bottom. Therefore, during the splicing and installation of the heat dissipation fins and the heat dissipation substrate, the first dovetail insert of the heat dissipation fin is inserted from the side into the first dovetail slot of the heat dissipation substrate. At this time, the second dovetail insert in the first dovetail slot is inserted into the second dovetail slot of the first dovetail insert. The positioning structure then positions the heat dissipation fins, thus achieving a snap-fit ​​splicing between the heat dissipation fins and the heat dissipation substrate. The double dovetail snap-fit ​​design, compared to the traditional vertical insertion of rectangular slots, greatly increases the contact area between the heat dissipation fins and the heat dissipation substrate, thereby significantly improving the heat conduction effect and ensuring overall heat dissipation performance. This solves the technical problem of poor heat conduction between the heat dissipation fins and the heat dissipation substrate in current snap-fit ​​splicing cold-forged heat sinks. Therefore, this utility model has the advantage of better heat conduction.

[0014] 2. The second dovetail insert of this utility model consists of a dovetail strip and a dovetail end. The dovetail end is narrow at the outer end and wide at the inner end. The cross-sectional dimensions of the inner end are the same as those of the dovetail strip. The top and bottom of the dovetail end are flush with the top and bottom of the dovetail strip. The two sides of the dovetail end are inclined in a V-shape. The cross-sectional dimensions of the second dovetail slot are the same as those of the outer end of the dovetail end. Therefore, when the second dovetail slot is inserted into the second dovetail insert, under the guidance of the inclined expansion surfaces of the dovetail end, the second dovetail slot will be expanded until the cross-section of the second dovetail slot is the same as that of the dovetail strip. At this time, the first dovetail insert is expanded simultaneously, so that the surface of the first dovetail insert and the surface of the first dovetail slot can make closer contact. This ensures the fixing effect of the double dovetail buckle and the sealing of the double dovetail buckle splice. Good sealing can further improve the heat conduction effect between the heat sink fins and the heat sink substrate. Attached Figure Description

[0023] like Figures 1 to 6As shown, the present invention relates to a snap-fit ​​splicing cold-forged radiator, including a heat dissipation base plate 1, a plurality of equidistant heat dissipation fins 2 arranged at the bottom of the heat dissipation base plate 1, a plurality of first dovetail slots 4 equidistantly opened at the top of the heat dissipation base plate 1, and the first dovetail slots 4 having openings at both ends, a second dovetail insert 6 arranged at the bottom center of the first dovetail slot 4, positioning structures 7 arranged at both ends of the second dovetail insert 6, a first dovetail insert 3 arranged at the bottom of the heat dissipation fins 2, a second dovetail slot 5 arranged at the bottom center of the first dovetail insert 3, the first dovetail insert 3 being inserted into the first dovetail slot 4, and the second dovetail insert 6 being inserted into the second dovetail slot 5;

[0024] When the heat sink fins 2 and the heat sink substrate 1 are spliced ​​and installed, the first dovetail insert 3 of the heat sink fins 2 is inserted from the side into the first dovetail slot 4 of the heat sink substrate 1. At this time, the second dovetail insert 6 in the first dovetail slot 4 will be inserted into the second dovetail slot 5 of the first dovetail insert 3. At this time, the positioning structure 7 positions the heat sink fins 2, thereby realizing the splicing of the heat sink fins 2 and the heat sink substrate 1. The double dovetail splicing form can greatly increase the contact area after the heat sink fins 2 and the heat sink substrate 1 are connected, compared with the traditional rectangular slot vertical insertion. This can greatly improve the heat conduction effect of the heat sink fins 2 and the heat sink substrate 1, and ensure the overall heat dissipation performance.

[0025] Specifically, the dovetail end 602 is located outside the first dovetail slot 4, and the second dovetail insert 6 has slots 603 at both ends, with the top of the slots 603 open. The positioning structure 7 is arranged inside the slots 603. The positioning structure 7 includes a spring 701 and a positioning block 702. The positioning block 702 is slidably arranged inside the slot 603, and the spring 701 is arranged at the bottom of the slot 603, with the top of the spring 701 connected to the bottom of the positioning block 702. The positioning block 702 is L-shaped, and an insert 703 is arranged on the side of the positioning block 702 facing the dovetail section 601. The bottom ends of the second dovetail slot 5 have insertion holes 501, which correspond to the insert 703. A rectangular rod 706 is movably arranged on the side of the positioning block 702 away from the insert 703, and a fixing plate 705 is horizontally arranged at the outer end of the rectangular rod 706. The fixing plate 705 faces the fixed rod 703. The two ends of one side of the positioning block 702 are symmetrically arranged with protrusions 707. The two ends of the second dovetail insert 6 are provided with positioning grooves 605 corresponding to the protrusions 707, and the positioning grooves 605 are connected to the slot opening 603. Before the heat dissipation fins 2 are inserted into the heat dissipation substrate 1, the positioning block 702 needs to be pressed into the slot opening 603, and then the fixing plate 705 is pushed so that the protrusions 707 of the fixing plate 705 are inserted into the positioning groove 605 to fix the positioning block 702. Then, after the heat dissipation fins 2 and the heat dissipation substrate 1 are spliced ​​together, the fixing plate 705 is pulled out so that the protrusions 707 of the fixing plate 705 are disengaged from the positioning groove 605. At this time, it rises and resets under the cooperation of the spring 701. At this time, the insert 703 of the positioning block 702 is inserted into the insertion hole 501, so as to further position the heat dissipation fins 2 and prevent the heat dissipation fins 2 from sliding on the heat dissipation substrate 1.

[0026] Furthermore, symmetrical sliding grooves 604 are provided on both sides inside the slot 603, and protrusions 704 are symmetrically arranged on both sides of the positioning block 702, with the protrusions 704 located inside the sliding grooves 604; with the cooperation of the sliding grooves 604 and the protrusions 704, the positioning block 702 can slide stably up and down inside the slot 603.

[0027] In an embodiment of this utility model, the second dovetail insert 6 includes a dovetail strip 601 and a dovetail end 602. The dovetail end 602 is symmetrically arranged at both ends of the dovetail strip 601. The dovetail end 602 is narrow at the outer end and wide at the inner end. The cross-sectional dimensions of the inner end of the dovetail end 602 are the same as those of the dovetail strip 601. The top and bottom of the dovetail end 602 are flush with the top and bottom of the dovetail strip 601. The two sides of the dovetail end 602 are arranged in a V-shape. The cross-sectional dimensions of the second dovetail slot 5 are the same as those of the outer end of the dovetail end 602.

[0028] When the second dovetail slot 5 is inserted into the second dovetail insert 6, guided by the V-shaped inclined expansion surfaces on both sides of the dovetail end 602, the second dovetail slot 5 will be expanded until the cross-section of the second dovetail slot 5 is the same as the cross-section of the dovetail strip 601. At this time, the first dovetail insert 3 is expanded simultaneously, so that the surface of the first dovetail insert 3 can make closer contact with the surface of the first dovetail slot 4. This ensures the fixing effect of the double dovetail buckle and the sealing of the double dovetail buckle splice. Good sealing can further improve the heat conduction effect between the heat sink fins 2 and the heat sink substrate 1.

[0029] Working principle: This embodiment provides a snap-fit ​​splicing cold forged heat sink. First, when the heat sink fins 2 and the heat sink base plate 1 are spliced ​​and installed, the first dovetail insert 3 of the heat sink fins 2 is inserted from the side into the first dovetail slot 4 of the heat sink base plate 1. At this time, the second dovetail insert 6 in the first dovetail slot 4 will be inserted into the second dovetail slot 5 of the first dovetail insert 3. At this time, the positioning structure 7 positions the heat sink fins 2, thereby realizing the snap-fit ​​splicing of the heat sink fins 2 and the heat sink base plate 1. The double dovetail snap-fit ​​form can greatly increase the contact area after the heat sink fins 2 and the heat sink base plate 1 are connected, compared with the traditional rectangular slot vertical insertion. This can greatly improve the heat conduction effect of the heat sink fins 2 and the heat sink base plate 1, and ensure the overall heat dissipation performance.

[0030] Secondly, when the second dovetail slot 5 is inserted into the second dovetail insert 6, under the guidance of the V-shaped inclined expansion surfaces on both sides of the dovetail end 602, the second dovetail slot 5 will be expanded until the cross-section of the second dovetail slot 5 is the same as the cross-section of the dovetail strip 601. At this time, the first dovetail insert 3 is expanded simultaneously, so that the surface of the first dovetail insert 3 can make closer contact with the surface of the first dovetail slot 4. This can ensure the fixing effect of the double dovetail buckle and the sealing of the double dovetail buckle splice. Good sealing can further improve the heat conduction effect between the heat sink fins 2 and the heat sink substrate 1.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
