They are called electronic products because early products primarily used vacuum tubes as their basic components.

[0003] Electronic products generally require heat dissipation through heat sinks. However, the heat sink devices used for electronic products on the market are not convenient for heat dissipation, and are cumbersome to operate and have poor practicality. Summary of the Invention

[0004] The object of the present invention is to provide a heat sink for electronic products to solve the above technical problems.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A heat sink for electronic products comprises a heat sink assembly, wherein a bottom box is provided on the top surface of the heat sink assembly, and a plurality of circulation components are evenly arranged in the bottom box. The bottom box is open on the bottom surface, and the bottom box is fixedly connected to the top surface of the heat sink assembly. A plurality of connecting tubes are evenly fixed on the top surface of the bottom box, and a cooling box is provided on the top end of the plurality of connecting tubes. The top end of each of the connecting tubes passes through the bottom surface of the cooling box and is connected and fixedly connected to the cooling box. A pair of symmetrical return pipes are provided on the top surface of the cooling box, and the bottom end of each of the return pipes passes through the top surface of the cooling box and is connected and fixedly connected to the cooling box. An arc pipe is provided between the top ends of the two return pipes, and the top end of each of the return pipes passes through the bottom surface of the arc pipe and is connected and fixedly connected to the bottom surface of the arc pipe.

[0007] Preferably, the heat sink assembly is provided with a film layer, a graphite layer, a brass layer, and an adhesive layer in sequence from top to bottom, the top surface of the adhesive layer is fixed with a brass layer, the top surface of the brass layer is fixed with a graphite layer, and the top surface of the graphite layer is fixed with a film layer.

[0008] Preferably, a number of L-shaped circulation pipes are evenly arranged between the arc-shaped pipe and the bottom box, the top end of each L-shaped circulation pipe passes through the top surface of the arc-shaped pipe and is connected and fixedly connected to the arc-shaped pipe, and the bottom end of each L-shaped circulation pipe passes through the top surface of the bottom box and is connected and fixedly connected to the bottom box.

[0009] Preferably, a water inlet pipe is provided on the left side of the cooling box, the right end of the water inlet pipe passes through the left side of the cooling box and is connected and fixed to the cooling box, and a threaded sealing cover is provided on the threaded sleeve of the left port of the water inlet pipe.

[0010] Preferably, the circulation assembly includes a circulation cylinder and a fixed cylinder. The circulation cylinder is open at the top and bottom. The bottom end of the circulation cylinder is fixedly connected to the top surface of the heat sink assembly. A heat expansion rubber is inserted into the circulation cylinder. A piston is provided in contact with the top end of the heat expansion rubber. The fixed cylinder passes through the top surface of the bottom box and is fixedly connected to the bottom box. A sliding rod is slidably provided in the fixed cylinder. A limit block is fixed on the top surface of the sliding rod.

[0014] The beneficial effects of the present invention are:

[0015] 1. The present invention injects alcohol into the cooling box. Since the cooling box is connected to the connecting cylinder, the alcohol flows into the connecting cylinder. When the heat sink assembly is heated, the heat expansion rubber expands due to heat transfer, driving the piston to rise and fall along the circulation cylinder, thereby driving the sliding rod to rise and fall, thereby driving the coarse sliding rod to slide along the sliding hole, facilitating the lifting of the fine sliding rod. Since the diameter of the coarse sliding rod is larger than that of the fine sliding rod, the alcohol in the connecting cylinder is driven to enter the bottom box through the sliding hole, thereby facilitating physical cooling of the heat sink assembly.

[0016] 2. The present invention has several L-shaped circulation pipes evenly spaced between the arc-shaped pipe and the bottom box. Each L-shaped circulation pipe has two ends connected and affixed to the arc-shaped pipe and the bottom box, respectively. The alcohol, which has evaporated due to heat, enters the arc-shaped pipe through the L-shaped circulation pipes. A pair of return pipes are fixedly connected to the top surface of the cooling box, each of which is connected and affixed to the arc-shaped pipes. This drives the evaporated alcohol into the return pipes and then into the cooling box, thus facilitating recycling and increasing the practicality of the device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without making any creative work are all within the scope of protection of the present invention.

[0023] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0024] Example

[0025] like Figure 1-4As shown, a heat sink for electronic products includes a heat sink assembly 22. The heat sink assembly 22 is provided with a film layer 8, a graphite layer 9, a brass layer 10, and an adhesive layer 4 from top to bottom. The top surface of the adhesive layer 4 is fixed with the brass layer 10, the top surface of the brass layer 10 is fixed with the graphite layer 9, and the top surface of the graphite layer 9 is fixed with the film layer 8. A bottom box 7 is provided on the top surface of the heat sink assembly 22, and several circulation components are evenly arranged in the bottom box 7. The bottom box 7 is open on the bottom surface, and the bottom box 7 is fixedly connected to the top surface of the heat sink assembly 22. Several connecting tubes 18 are evenly fixed on the top surface of the bottom box 7, and a cooling box 3 is provided on the top end of the several connecting tubes 18. The top end of each connecting tube 18 passes through the bottom surface of the cooling box 3 and is connected and fixedly connected to the cooling box 3. A water inlet pipe 13 is provided on the left side surface of the cooling box 3, and the right end of the water inlet pipe 13 passes through the left side surface of the cooling box 3 and is connected and fixedly connected to the cooling box 3. A threaded sealing cover 12 is provided on the threaded sleeve of the left port of the water inlet pipe 13. A pair of symmetrical return pipes 2 are provided on the top surface of the cooling box 3. The bottom end of each return pipe 2 passes through the top surface of the cooling box 3 and is connected and fixed to the cooling box 3. An arc tube 1 is provided between the top ends of the two return pipes 2. The top end of each return pipe 2 passes through the bottom surface of the arc tube 1 and is connected and fixed to the bottom surface of the arc tube 1.

[0026] Several L-shaped circulation pipes 6 are evenly arranged between the arc-shaped pipe 1 and the bottom box 7. The top end of each L-shaped circulation pipe 6 passes through the top surface of the arc-shaped pipe 1 and is connected and fixed to the arc-shaped pipe 1. The bottom end of each L-shaped circulation pipe 6 passes through the top surface of the bottom box 7 and is connected and fixed to the bottom box 7.

[0027] The circulation assembly includes a circulation cylinder 5 and a fixed cylinder 16. The circulation cylinder 5 is open at the top and bottom. A limit ring 14 is provided inside the top surface port of the circulation cylinder 5. The outer wall of the limit ring 14 is fixedly connected to the inner wall of the circulation cylinder 5. The limit ring 14 plays a good limiting role. The bottom end of the circulation cylinder 5 is fixedly connected to the top surface of the heat sink assembly 22. A thermal expansion rubber 11 is inserted into the circulation cylinder 5. The top of the thermal expansion rubber 11 is contacted with a piston 20. The fixed cylinder 16 passes through the top surface of the bottom box 7 and is fixed to the bottom box 7. The fixed cylinder 16 is located in the connecting cylinder 18. A slide rod 17 is slidably provided in the fixed cylinder 16. A limit block 21 is fixed to the top surface of the slide rod 17. The bottom end of the slide rod 17 is fixedly connected to the top of the piston 20.

[0028] A pair of symmetrical sliding holes are provided on either side of the fixed cylinder 16. A coarse sliding rod 15 slides in each sliding hole. A fine sliding rod 19 is fixed to the bottom end of each coarse sliding rod 15. The bottom end of each fine sliding rod 19 is fixed to the top end of the piston 20. The diameter of each coarse sliding rod 15 is larger than the diameter of the fine sliding rod 19.

[0029] Working principle: First, by rotating the threaded sealing cover 12 in the reverse direction, the threaded sealing cover 12 is driven to rotate along the water inlet pipe 13, so that the threaded sealing cover 12 leaves the water inlet pipe 13, and an appropriate amount of alcohol is injected into the cooling box 3 through the water inlet pipe 13. Then, the threaded sealing cover 12 is rotated in the forward direction, which drives the threaded sealing cover 12 to rotate along the water inlet pipe 13, so that the threaded sealing cover 12 blocks the water inlet pipe 13. Since the connecting tube 18 is connected and fixed to the water inlet pipe 13, the alcohol enters the connecting tube 18 through the cooling box 3;

[0030] Secondly, when the heat sink assembly 22 is heated, the heat expansion rubber 11 is expanded due to the heat transfer. As the heat expansion rubber 11 is heated and becomes larger, it drives the piston 20 to move up and down along the circulation tube 5, thereby driving the slide rod 17 to move up and down and slide along the fixed tube 16, thereby driving the coarse slide rod 15 to slide along the slide hole, facilitating the lifting and sliding of the fine slide rod 19. Since the diameter of the coarse slide rod 15 is larger than that of the fine slide rod 19, the alcohol in the connecting tube 18 is driven to enter the bottom box 7 through the slide hole, thereby facilitating the physical cooling operation of the heat sink assembly 22.

[0031] Finally, because alcohol absorbs heat and is prone to volatilization, several L-shaped circulation pipes 6 are evenly arranged between the arc tube 1 and the bottom box 7. The top of each L-shaped circulation pipe 6 penetrates the top surface of the arc tube 1, is connected to and fixedly connected to the arc tube 1, and the bottom of each L-shaped circulation pipe 6 penetrates the top surface of the bottom box 7, is connected to and fixedly connected to the bottom box 7. The alcohol that has evaporated due to heat enters the arc tube 1 through the L-shaped circulation pipe 6. Because the top surface of the cooling box 3 is provided with a pair of symmetrical return pipes 2, the bottom end of each return pipe 2 penetrates the top surface of the cooling box 3, is connected to and fixedly connected to the cooling box 3, and the arc tube 1 is arranged between the top ends of the two return pipes 2, and the top end of each return pipe 2 penetrates the bottom surface of the arc tube 1, is connected to and fixedly connected to the bottom surface of the arc tube 1. This drives the volatilized alcohol into the return pipes 2 and then into the cooling box 3, thereby facilitating recycling and increasing the practicality of the device.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
