Description

Technical Field

[0001] The utility model relates to the field of heat sinks, in particular to a heat sink convenient for assembly. Background Art

[0002] The CPU, whose full name is Central Processing Unit and is called the central processing unit in Chinese, is the core component of a computer system. It is responsible for executing program instructions, processing data, and controlling the operation of other devices in the computer system. In short, the CPU is the "brain" of the computer and is responsible for performing all computing and control tasks. When the CPU is working, it generates a large amount of heat, so it needs to be cooled by a CPU heat sink. The heat sink is a hardware component specifically designed to reduce the temperature of the CPU. Its main function is to effectively dissipate the heat generated by the CPU into the surrounding environment through heat transfer methods such as conduction, convection, and radiation, so as to keep the CPU operating within a relatively low and stable temperature range.

[0003] The existing heat sinks still have the following defects: The design of multiple fins is adopted to increase the heat dissipation area, form a convection path, quickly dissipate heat, promote the heat dissipation layer to absorb heat for heat dissipation, and at the same time increase the top surface, which can further increase the heat dissipation area and enhance the heat dissipation effect. Existing different models of CPUs require corresponding heat sinks with different areas. When it is necessary to enhance the heat dissipation effect, a heat sink with a larger area needs to be replaced. The heat sink is usually a whole structure, installed on the circuit board by fasteners such as screws, and then contacts the CPU through the heat sink to transfer heat and achieve the function of heat dissipation. Therefore, the lengths of the heat sinks required for different models of CPUs are different, and the areas are also different. The whole heat sink cannot be spliced, and heat sinks of multiple size models are required to meet the needs of different models of CPUs, which is very troublesome and inconvenient to assemble multiple heat sinks to increase their heat dissipation area and splice multiple heat sinks to meet the needs of different models of CPUs. Summary of the Utility Model

[0004] In order to overcome the deficiencies of the prior art solutions, the utility model provides a heat sink convenient for assembly, which can effectively solve the technical problem that the existing heat sinks are inconvenient for assembly.

[0005] The technical solution adopted by the utility model to solve its technical problems is: A heat sink convenient for assembly, including a fixing plate and a splicing plate. Heat dissipation plates are arranged on the top surfaces of the fixing plate and the splicing plate. Fixing grooves are opened on both sides of the fixing plate, and the fixing grooves extend along the fixing plate. Splicing strips are formed outward on both sides of the splicing plate, and the splicing strips are slidably connected with the fixing grooves. A recessed groove recessed into the splicing strip is opened on the top surface of the splicing strip, and a metal elastic sheet is fixedly arranged on the surface of the splicing strip, and the metal elastic sheet extends into the recessed groove.

[0006] Further, a plurality of fins are formed by extending the top surface of the heat dissipation plate outward, and the plurality of fins are arranged equidistantly.

[0007] Further, the length of the splicing strip is adapted to the length of the fixing groove.

[0008] Further, screw holes are provided on the top surfaces of the fixing plate, the splicing plate and the heat dissipation plate.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Such as Figures 1-4As shown in the figure, a heat sink that is easy to assemble includes a fixing plate 1 and a splicing plate 2. Heat dissipation plates 3 are provided on the top surfaces of both the fixing plate 1 and the splicing plate 2. Fixing grooves 6 are opened on both sides of the fixing plate 1, and the fixing grooves 6 extend along the fixing plate 1. Splicing strips 7 are formed outwardly on both sides of the splicing plate 2, and the splicing strips 7 are slidably connected to the fixing grooves 6. A recessed groove 8 that recesses into the interior of the splicing strip 7 is opened on the top surface of the splicing strip 7. A metal elastic sheet 9 is fixedly provided on the surface of the splicing strip 7, and the metal elastic sheet 9 extends into the recessed groove 8. A plurality of fins 4 extend outwardly from the top surface of the heat dissipation plate 3, and the plurality of fins 4 are arranged equidistantly, effectively increasing the heat dissipation area and thus improving the heat dissipation efficiency. The design of the fins 4 makes the air flow more smoothly, and the heat can be taken away faster. The length of the splicing strip 7 is adapted to the length of the fixing groove 6, and the length of the splicing strip 7 is adapted to the length of the fixing groove 6, ensuring that the splicing plate 2 can be accurately and stably inserted into the fixing groove 6, avoiding the assembly difficulty caused by size mismatch. Screw holes 5 are provided on the top surfaces of the fixing plate 1, the splicing plate 2, and the heat dissipation plate 3. Through fasteners such as screws, the heat sink can be firmly installed on the device or component that needs heat dissipation. Both the fixing groove 6 and the splicing strip 7 are in a T shape, and the T-shaped structure can provide a better guiding effect, enabling the splicing strip 7 to be accurately inserted into the fixing groove 6 without error.

[0019] In a heat sink that is easy to assemble according to this embodiment, by setting the structures of the fixing plate 1 and the splicing plate 2, where the fixing plate 1 is provided with fixing grooves 6 and the splicing plate 2 is provided with splicing strips 7 that match the fixing grooves 6, rapid and simple assembly of the heat sink is achieved. This not only improves the assembly efficiency but also reduces the assembly difficulty. During use, the fixing plate 1 and the splicing plate 2 are spliced, so that the splicing strips 7 on both sides of the splicing plate 2 slide into the fixing grooves 6 on both sides of the fixing plate 1, and the metal elastic sheets 9 on the top surface of the splicing strips 7 slide into the interior of the fixing grooves 6. Through the metal elastic sheets 9, the splicing strips 7 can be better engaged with the fixing grooves 6, which can prevent loosening between the fixing plate 1 and the splicing plate 2. After fixing, the heat dissipation plate 3 is placed on the top surfaces of the fixing plate 1 and the splicing plate 2, and by inserting long screws into the screw holes 5, the heat dissipation plate 3 is installed on the fixing plate 1 and the splicing plate 2, and the long screws penetrate through the fixing plate 1 and the splicing plate 2. Through the long screws, the entire heat sink is further installed on the device that needs heat dissipation. When different devices require heat sinks with different areas, it is convenient to assemble.
