Description

Technology Field

[0001] The present invention relates to a press device for manufacturing a heat sink, and more specifically, to a press device for manufacturing a heat sink that allows for the convenient connection of individually manufactured heat dissipation plates and heat dissipation fin members by forming a compression catch portion at the end of the coupling projection when the lifting striking portion descends by the operation of the cylinder portion while the seating support portion supports a heat dissipation plate and a heat dissipation fin member fitted into the coupling projection portion. Background Technology

[0003] Generally, a heat sink is installed in products that require heat dissipation to enable effective heat dissipation.

[0004] These heat sinks are applied to various products in industries such as LED lighting, semiconductor manufacturing equipment, computers, electronics, machinery, and the automotive sector to prevent heat-induced damage and ensure stable operation.

[0005] Such a heatsink is configured with a heatsink body on which a product requiring heat dissipation is mounted, and multiple heat dissipation fins positioned on the side of the heatsink body opposite to where the product is mounted, thereby rapidly dissipating heat generated by the product through heat exchange with the air.

[0006] Most of these heatsinks are manufactured by extrusion or casting and have a structure in which a heat sink body and multiple heat dissipation fins are integrally formed.

[0007] However, since conventional heat sinks have the heat plate and heat fins formed as a single unit, it is very difficult to reduce the thickness and spacing of the multiple heat fins. Furthermore, if the number of heat fins is reduced, it not only degrades heat dissipation performance but also presents the problem of being difficult to lighten the overall weight.

[0008] In addition, conventional heat sinks are manufactured by extrusion or casting, and since the molds must be designed to be complex to form multiple heat dissipation fins, as well as molds must be produced separately in shapes corresponding to each product, there is a problem of reduced workability due to high production costs and time.

[0009] Therefore, there is a need to improve this.

[0010] A related background technology is Korean Published Patent Application No. 10-2024-0016878 (February 6, 2024. Title: Heatsink structure and method for manufacturing the same). The problem to be solved

[0012] The present invention was created out of the aforementioned necessity, and aims to provide a press device for manufacturing a heat sink that can easily connect a heat dissipation plate and a heat dissipation fin member, each manufactured individually, by forming a compression catch portion at the end of the coupling projection when the lifting striking portion descends by the operation of the cylinder portion while the mounting support portion supports the heat dissipation plate and the heat dissipation fin member fitted into the coupling projection portion. means of solving the problem

[0015] The above-described mounting support member is characterized by including a mounting jig fixedly installed on the lower plate of the workbench to support the heat dissipation plate so as to be mounted thereon, and an upright support member connected to the mounting jig to support the heat dissipation plate so that the heat dissipation plate is positioned upright.

[0016] The portion of the heat dissipation plate that is seated on the seating jig has a plurality of recessed grooves corresponding to the coupling protrusions formed therein, and the seating jig has fitting protrusions formed therein that are fitted into each of the recessed grooves when the heat dissipation plate is seated therein.

[0017] The above-described standing support member is characterized by having a plurality of receiving spaces formed to accommodate each of the above-described heat dissipation fin members in a partitionable manner.

[0018] The above lifting striking member is characterized by including a lifting jig that is fixedly fitted to the end of the rod and a striking member that is fixedly installed on the lower side of the lifting jig and strikes the coupling projection by passing through the receiving space so that the compression catch portion is formed on the coupling projection.

Specific details for implementing the invention

[0023] Hereinafter, an embodiment of a press device for manufacturing a heat sink according to the present invention will be described with reference to the attached drawings. In this process, the thickness of the lines or the size of the components shown in the drawings may be exaggerated for clarity and convenience of explanation.

[0024] Furthermore, the terms described below are defined in consideration of their functions in the present invention, and these may vary depending on the intent or practice of the user or operator. Therefore, the definitions of these terms should be based on the content throughout this specification.

[0026] FIG. 1 is a perspective view illustrating a press device for manufacturing a heat sink according to one embodiment of the present invention, FIG. 2 is an exploded perspective view illustrating a press device for manufacturing a heat sink according to one embodiment of the present invention, FIG. 3 is a front view illustrating a press device for manufacturing a heat sink according to one embodiment of the present invention, and FIG. 4 is an operation diagram illustrating the operating state of a lifting striking part in a press device for manufacturing a heat sink according to one embodiment of the present invention.

[0028] As illustrated in FIGS. 1 to 4, a press device for manufacturing a heat sink according to one embodiment of the present invention includes a workbench (10), a seating support part (20), a cylinder part (30), and a lifting striking part (40).

[0029] The workbench (10) provides a space in which the mounting jig (20) and the cylinder part (30) are installed so as to be operable.

[0030] The work table (10) includes a lower plate (11) that can fixably support a seating jig (20), an upper plate (12) spaced apart from the lower plate (11) and can fixably support a cylinder part (30), and a plurality of connecting poles (13) provided between the lower plate (11) and the upper plate (12) to connect the lower plate (11) and the upper plate (12).

[0031] At this time, a through hole (12a) is formed in the center of the upper plate (12) so that the rod (31) of the cylinder part (30) can move axially.

[0032] And, the mounting support member (20) is provided on the workbench (10) and supports a heat dissipation plate (100) having a plurality of coupling protrusions (110) formed thereon, and a plurality of heat dissipation fin members (200) that are mounted upright on the heat dissipation plate (100) while being fitted into the coupling protrusions (110).

[0033] Here, the heat dissipation plate (100) is formed in a flat plate shape with a constant thickness, and a plurality of connecting protrusions (110) are formed to protrude at regular intervals along the horizontal and vertical directions of the heat dissipation plate (100).

[0034] Additionally, the heat dissipation fin member (200) is seated on the heat dissipation plate (100) to receive heat from the heat dissipation plate (10), and includes a seating portion (210) having a plurality of coupling holes (211) formed to be fitted into a coupling projection (110), and a heat dissipation wing portion (220) that is formed to extend orthogonally from both ends of the seating portion (210) to exchange heat with air.

[0035] Specifically, the mounting support member (20) includes a mounting jig (21) that is fixedly installed on the lower plate (11) of the workbench (10) to support the heat dissipation plate (100) so as to be mounted, and a standing support member (22) that is connected to the mounting jig (21) and supports the heat dissipation fin member (200) so that the heat dissipation fin member (200) is positioned upright.

[0036] At this time, in the portion of the heat dissipation plate (100) that is seated on the seating jig (21), a plurality of concave grooves (120) corresponding to the coupling protrusions (110) are formed by being recessed, and in the seating jig (21), a plurality of fitting protrusions (21a) are formed so as to be fitted into each of the concave grooves (120) when the heat dissipation plate (100) is seated.

[0037] Thus, when the heat dissipation plate (100) is placed on the seating jig (21) so that the concave groove (120) is fitted into the fitting projection (21a), the heat dissipation plate (100) can be prevented from moving on the seating jig (21) when the lifting striking part (40) strikes the coupling projection (110) in a way that allows it to be compressed, thereby improving the quality of the processing.

[0038] And, the standing support member (22) is formed such that a plurality of receiving spaces (22a) each receiving a heat dissipation fin member (200) can be partitioned.

[0039] At this time, the number of receiving spaces (22a) corresponds to the number of heat dissipation fin members (200) seated on the heat dissipation plate (100), and it is preferable that the width of the receiving spaces (22a) be formed to be the same width as the width of the heat dissipation fin members (200).

[0040] Thus, since the plurality of heat dissipation fin members (200) can be arranged to stand upright while partitioned by the receiving space (22a) when fitted into the coupling projection (110) of the heat dissipation plate (100), the alignment state can be stably maintained during the process in which the lifting striking part (40) strikes the coupling projection (110) in a way that allows it to be compressed, thereby preventing damage caused by pressure applied to the lifting striking part (40).

[0041] In addition, the cylinder part (30) is provided on the upper plate (12) of the work table (10) and is provided with a rod (31) that extends toward the seating support part (20). This cylinder part (30) performs the function of moving the lifting striking part (40) up and down through the extension of the rod (31).

[0042] That is, the lifting striking part (40) descends along the direction of protrusion of the rod (31) inside the work table (10) when the rod (31) protrudes from the cylinder part (30), and ascends along the direction of insertion of the rod (31) inside the work table (10) when the rod (31) is inserted into the cylinder part (30).

[0043] Meanwhile, the lifting striking part (40) is connected to the rod (31) of the cylinder part (30) and moves up and down on the inside of the work table (10), and when lowering, strikes the coupling protrusion part (110) in the axial direction to form a compression catch part (130) at the end of the coupling protrusion part (110).

[0044] Accordingly, the heat dissipation fin member (200) can be supported by being caught on the heat dissipation plate (100) by the compression catch portion (130) formed at the end of the coupling portion (110) while being fitted into the coupling portion (110), so that it can be connected to the heat dissipation plate (100) so as not to detach while receiving heat from the heat dissipation plate (100).

[0045] At this time, the lifting striking part (40) includes a lifting jig (41) that is fixedly fitted to the end of the rod (30) and a striking member (42) that is fixedly installed on the lower side of the lifting jig (41) and inserted into the heat dissipation wing part (22) to strike the connecting protrusion part (110) so that a compression catch portion (130) is formed on the connecting protrusion part (110).

[0046] Here, the striking member (42) includes a mounting part (42a) mounted on the lifting jig (41) and a plurality of deformation compression parts (42b) that are extended from the mounting part (42a) at regular intervals and deformably compress the coupling projection part (110).

[0047] That is, when the rod (31) is inserted into the interior of the cylinder part (30) and the lifting jig (41) and the striking member (42) rise simultaneously, the heat dissipation plate (100) can be placed on the seating jig (21) and then inserted into the coupling protrusion (110) of the heat dissipation plate (100) in the coupling hole part (211) of the plurality of heat dissipation fin members (200), or the heat dissipation plate (100) with the heat dissipation fin members (200) assembled can be removed from the seating jig (21).

[0048] Conversely, when the rod (31) protrudes from the cylinder portion (30) and the lifting jig (41) and the striking member (42) descend simultaneously, the deformed compression portion (42) of the striking member (42) is inserted into the heat dissipation fin member (200) received in the receiving space portion (22a) and presses the coupling projection portion (110). At this time, a compression catch portion (130) is formed at the end of the coupling projection portion (110) by the pressure of the deformed compression portion (42), thereby preventing the heat dissipation fin member (200) from detaching from the heat dissipation plate (100).

[0049] Accordingly, since the heat dissipation plate (100) and the heat dissipation fin member (200) can be easily connected to each other, the heat dissipation fin member (200) can be manufactured individually while minimizing its thickness, thereby reducing manufacturing costs and improving productivity.

[0051] Although the present invention has been described with reference to the embodiments illustrated in the drawings, this is merely illustrative, and those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible therefrom.

[0052] Therefore, the true technical scope of protection of the present invention should be determined by the following claims. Explanation of the symbols
