However, high-performance hardware configuration and continuous data processing capabilities are often accompanied by a significant increase in heat generation. Traditional heat dissipation solutions, such as relying solely on fan cooling or natural convection, can no longer meet the heat dissipation requirements of modern fiber optic switches in high-density, high-load application environments. This will not only cause equipment overheating and performance degradation, but in severe cases it may even cause system crashes, affecting the stability and reliability of network services. Utility Model Content

[0006] The heat dissipation structure also includes a heat collecting plate, heat dissipation fins, a special-shaped water pipe, a liquid inlet and a liquid outlet. The heat collecting plate is fixedly mounted on the back of the heat dissipation plate, a plurality of heat dissipation fins are fixedly connected to one side of the heat collecting plate, the special-shaped water pipe is arranged on the other side of the heat collecting plate, the liquid inlet is opened at one end of the special-shaped water pipe, and the liquid outlet is located at the other end of the special-shaped water pipe.

[0007] Furthermore, the wall of the special-shaped water pipe penetrates the side of the heat dissipation fin, and the special-shaped water pipe is made of copper.

[0008] Furthermore, one end of the liquid inlet and the liquid outlet penetrates the outer wall of the heat dissipation fixing frame, and the outer ends of the liquid inlet and the liquid outlet are opened outside the heat dissipation fixing frame.

[0009] Furthermore, a built-in heat absorbing plate is fixedly mounted on one side of the heat dissipation fixing frame, and the built-in heat absorbing plate passes into the interior of the optical fiber switch.

[0010] Furthermore, a plurality of slots are provided on one side of the heat collecting plate, and insulating bushings are fixedly mounted in the slots.

[0011] Furthermore, the insulating bushing is fitted inside the slot, and the insulating bushing is made of insulating plastic material.

[0012] Furthermore, a switching plug is provided at one end of the optical fiber switch.

[0013] Beneficial effects of the utility model:

[0014] The utility model discloses that by integrating a heat sink on the top of the heat dissipation fixed frame and assembling a high-efficiency heat dissipation component, the heat collector and the heat dissipation fin design are combined to achieve rapid heat conduction and dissipation, greatly improve the heat dissipation efficiency, effectively control the operating temperature of the equipment, and ensure the stable operation of the optical fiber switch under high load conditions. At the same time, a liquid cooling circulation mechanism consisting of special-shaped water pipes is introduced, and the excellent thermal conductivity of copper is used to quickly transfer the heat collected by the heat collector to the circulating liquid, and then connected to the external cooling system through the liquid inlet and outlet, forming a closed-loop heat dissipation, which greatly improves the heat dissipation rate and heat dissipation effect.

DETAILED DESCRIPTION

[0024] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0025] See also Figure 1-Figure 5 In this embodiment: a heat dissipation structure of an optical fiber switch includes a heat dissipation fixing frame 1 arranged on the top of the optical fiber switch 5, a heat dissipation plate 2 is fixedly mounted inside the heat dissipation fixing frame 1, and a heat dissipation member 201 is provided on one side of the heat dissipation plate 2;

[0026] The heat dissipation structure also includes a heat collecting plate 3, heat dissipation fins 301, a special-shaped water pipe 303, a liquid inlet 304 and a liquid outlet 305. The heat collecting plate 3 is fixedly assembled on the back of the heat dissipation plate 2, and a plurality of heat dissipation fins 301 are fixedly connected to one side of the heat collecting plate 3. The special-shaped water pipe 303 is arranged on the other side of the heat collecting plate 3. The liquid inlet 304 is opened at one end of the special-shaped water pipe 303, and the liquid outlet 305 is located at the other end of the special-shaped water pipe 303.

[0027] It should be noted that the heat dissipation fixing frame 1 is made of lightweight and high-strength materials such as aluminum alloy and is fixed to the top of the optical fiber switch 5. A heat sink 2 is precisely installed inside the frame. The heat sink 2 is usually made of a high thermal conductivity metal such as copper or aluminum to ensure good thermal conductivity. A heat sink 201 is installed on one side of the heat sink 2. The heat sink 201 is preferably a copper heat sink to enhance air convection and accelerate heat dissipation. The heat collecting plate 3 is close to the back of the heat collecting plate 2 and is fixed by fasteners or welding. The heat collecting plate 3 also uses a high thermal conductivity material to collect and transfer the heat transferred from the inside of the optical fiber switch 5. The heat dissipation fins 301 are vertically fixed to one side of the heat collecting plate 3 to increase the surface area and optimize the heat radiation and convection effects. And the heat dissipation fins 301 are preferably set to have a special geometric shape to improve the heat exchange efficiency when air flows.

[0028] In an optional embodiment: the wall of the special-shaped water pipe 303 penetrates the side of the heat dissipation fin 301, and the special-shaped water pipe 303 is made of copper.

[0029] It should be noted that the special-shaped water pipe 303 is made of copper. Due to the thermal conductivity of copper, the heat collected by the heat collecting plate can be quickly transferred. The water pipe wall is specially designed to penetrate part of the side of the heat dissipation fin 301, which not only tightly connects the two, but also increases the heat exchange interface, further improving the cooling efficiency. The two ends of the water pipe are respectively provided with a liquid inlet 304 and a liquid outlet 305 for the circulation of liquid in and out to achieve liquid cooling.

[0030] In an optional embodiment: one end of the liquid inlet 304 and the liquid outlet 305 both penetrate the outer wall of the heat dissipation fixing frame 1 , and the outer ends of the liquid inlet 304 and the liquid outlet 305 are opened outside the heat dissipation fixing frame 1 .

[0031] It should be noted that the liquid inlet 304 and the liquid outlet 305 are precisely processed so that they can penetrate the outer wall of the heat dissipation fixing frame 1, and an external port for convenient connection is set outside the frame to facilitate connection to an external cooling circulation system to achieve efficient liquid circulation heat dissipation.

[0032] In an optional embodiment: a built-in heat absorbing plate 101 is fixedly mounted on one side of the heat dissipation fixing frame 1 , and the built-in heat absorbing plate 101 penetrates into the interior of the optical fiber switch 5 .

[0033] It should be noted that a built-in heat absorbing plate 101 is fixedly installed on one side of the heat dissipation fixing frame 1. This heat absorbing plate goes deep into the fiber optic switch 5, directly contacts or is close to the heating element, and more directly absorbs and transfers heat to the external heat dissipation system to reduce internal heat accumulation.

[0034] In an optional embodiment: a plurality of slots 302 are provided on one side of the heat collecting plate 3, and an insulating bushing 4 is fixedly installed in the slot 302. The insulating bushing 4 is installed in the slot 302, and the insulating bushing 4 is made of insulating plastic material.

[0035] It should be noted that a plurality of slots 302 are preset on one side of the heat collecting plate 3, and an insulating bushing 4 is precisely installed in each slot to protect and isolate the electronic components that may be in contact with it to avoid the risk of short circuit. The insulating bushing is made of high temperature resistant and corrosion resistant insulating plastic material to ensure electrical safety while not hindering heat conduction.

[0036] In an optional embodiment: one end of the optical fiber switch 5 is provided with a switching plug 6. The optical fiber switch 5 is provided with a switching plug 6 at one end, which is convenient for quickly connecting or disconnecting the optical fiber line, installing, maintaining or upgrading the equipment, and ensuring the stability and security of signal transmission.

[0037] Working principle: The heat generated by the optical fiber switch 5 during operation is first collected by the built-in heat absorbing plate 101. Since the heat absorbing plate 101 is deep inside the switch and close to the heat source, it can quickly absorb and conduct the heat to the heat collecting plate 3 on the back. The heat collecting plate 3 uses its high thermal conductivity to evenly distribute the heat and further transfer it to the heat sink 2. The heat sink 201 assembled on the heat sink 2 dissipates the heat conducted by the heat sink 2 into the surrounding environment. The ambient air is effectively used as a cooling medium to initially reduce the system temperature. At the same time, the wall of the copper special-shaped water pipe 303 on the other side of the heat collecting plate 3 penetrates the heat sink fin 301. While the heat is being conducted, the internally circulating coolant such as special cooling water or coolant enters from the liquid inlet 304, flows through the inside of the special-shaped water pipe 303, absorbs the heat on the heat collecting plate 3 and the heat sink fin 301, and then is discharged through the liquid outlet 305 to complete a cycle. The high specific heat capacity characteristics of the liquid are fully utilized to achieve efficient heat energy transfer.

[0038] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
