[0002] A router is a gateway device whose main functions are to realize information transfer, network interconnection, data processing, network management, etc. An antenna is installed on the router shell to realize signal transmission. A signal processing unit is installed on the circuit board inside the shell, which will generate heat during use. Therefore, a heat dissipation structure is set on the router shell to prevent the circuit board from being damaged by high temperature.

[0003] In actual use, most existing routers have grid-type or multi-hole (both open) heat dissipation ports reserved on the casing to ensure that the heat inside the casing is discharged and prevent the circuit board from being damaged in a high temperature environment. However, the heat dissipation ports with open structures are prone to external dust entering the router casing. Long-term use will cause a lot of dust to accumulate on the circuit board, which in turn hinders the normal heat dissipation of the circuit board and significantly reduces its service life.

[0004] In view of this, the present application proposes a router with a cooling structure that can effectively dissipate heat and prevent dust. Summary of the invention

[0005] The utility model aims to solve the problem in the background technology that dust easily enters the inside of the router from the heat dissipation port and causes dust accumulation on the surface of the circuit board, and proposes a router with a cooling structure that can effectively dissipate heat and prevent dust.

[0027] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments. Example

[0028] like Figure 1-Figure 4 As shown, the utility model proposes a router with a cooling structure, including a shell 1, a heat dissipation cover 2 is fixedly installed on the top of the shell 1, a partition 21 is provided on the heat dissipation cover 2, and a groove structure is formed above the partition 21. A plurality of hollow heat sinks 3 are fixedly inserted on the partition 21, and a heat dissipation opening 33 is provided at the bottom of the hollow heat sink 3, so that the heat in the shell 1 can enter the hollow heat sink 3, and the heat dissipation openings 31 opened on both sides of the top of the hollow heat sink 3 can be used as openings for heat dissipation; a V-shaped dustproof net 34 is fixedly installed inside the hollow heat sink 3, and the V-shaped dustproof net 34 is inverted and its two ends away from each other are fixed to the corresponding heat dissipation openings. At the position below 31, an inclined dustproof net structure is adopted, which is beneficial for dust on the surface of the V-shaped dustproof net 34 to slide downward; a heat dissipation bracket 6 is fixedly installed at the bottom of the shell 1, and the heat dissipation bracket 6 is provided with an air inlet channel 62, which can allow air outside the router to enter the shell 1, and the air at normal temperature or low temperature forms convection with the high-temperature air inside the shell 1, so that the hot air is transported upward, and the efficiency of hot air being discharged outward from the hollow heat sink 3 is accelerated; a circuit board 7 is fixedly installed in the shell 1, and the circuit board 7 is arranged at a position between the hollow heat sink 3 and the heat dissipation bracket 6 to ensure the heat dissipation of the circuit board 7, and a dustproof net structure is also installed inside the heat dissipation bracket 6, which improves the dustproof effect of the router.

[0029] Furthermore, the top of the hollow heat sink 3 is arranged in the groove structure at the top of the heat sink cover 2, and a magnetic dustproof net 5 is installed at the notch of the above-mentioned groove structure. The magnetic dustproof net 5 is erected on the top of a number of hollow heat sinks 3 and is magnetically attracted thereto, thereby preventing a large amount of dust from falling into the groove structure, reducing the probability of dust entering the hollow heat sink 3 from the heat dissipation port 31, and enhancing the dustproof effect of the router.

[0030] Secondly, a positioning plate 32 is fixedly installed on the outer wall of the hollow heat sink 3, the top of the hollow heat sink 3 passes through the hole drilled on the partition 21, and then the positioning plate 32 is fixed to the lower surface of the partition 21, ensuring that the hollow heat sink 3 can be firmly installed on the heat dissipation cover 2; an antenna 4 is fixedly installed on the outer shell 1, and the antenna 4 can transmit network signals. A bracket 11 is fixedly installed inside the outer shell 1, and the two ends of the circuit board 7 that are far away from each other are mounted on the top of the bracket 11 and fixed with bolts, ensuring that the circuit board 7 can be firmly installed inside the outer shell 1.

[0031] Furthermore, a built-in dustproof net 61 is fixedly installed inside the heat dissipation bracket 6, and the dustproof net structure is arranged above the air inlet channel 62. When the outside air enters the interior of the shell 1 from the air inlet channel 62, the above-mentioned built-in dustproof net 61 can intercept a large amount of dust, thereby reducing the probability of dust entering the interior of the shell 1; a dust collecting hopper 63 is provided inside the heat dissipation bracket 6, and the dust collecting hopper 63 is connected to the air inlet channel 62 and is arranged below the built-in dustproof net 61. A bottom cover 64 is snap-fitted and installed at the bottom end of the heat dissipation bracket 6. The dust intercepted by the built-in dustproof net 61 falls into the dust collecting hopper 63 and is finally collected in the bottom cover 64. The dust can be cleaned by opening the bottom cover 64, and the operation is convenient.

[0032] In this embodiment, first, when the router is in use, various electrical components on the circuit board 7 will generate heat, and then high-temperature hot air will be formed in the shell 1. At this time, the air outside the shell 1 is lower in temperature than the high-temperature hot air in the shell 1, and can be regarded as normal temperature or low-temperature air. When the outside air enters the shell 1 from the air inlet channel 62, it convects with the high-temperature hot air in the shell 1, so that the high-temperature hot air is quickly transported upward, and then the high-temperature hot air in the shell 1 is quickly discharged along the hollow heat sink 3, thereby enhancing the heat dissipation performance of the router. By accelerating the heat dissipation, the router can play the function of active cooling, preventing the circuit board 7 from being damaged in a high-temperature environment.

[0033] Since the air inlet channel 62 and the heat dissipation port 31 on the hollow heat sink 3 are both open structures, if dust enters the housing 1 from the open structure, the dust will cover the surface of the circuit board 7. In order to prevent the dust from covering and affecting the normal heat dissipation of the circuit board 7, the present application installs an inverted V-shaped dustproof net 34 in the hollow heat sink 3, which can intercept external dust. Even if a small amount of dust covers the outer surface of the V-shaped dustproof net 34, this part of the dust can slide down along the inclined surface of the V-shaped dustproof net 34, so that the dust is concentrated in the groove structure at the top of the partition 21; the built-in dustproof net 61 installed inside the heat dissipation bracket 6 can intercept the dust entering from the outside and reduce the probability of dust entering the housing 1. The intercepted dust is concentrated in the bottom cover 64, and the bottom cover 64 can be removed to clean the dust; the present application installs dustproof nets at the air inlet and the heat exhaust port. Under the premise of ensuring the heat dissipation of the router, it can reduce the probability of dust entering the housing 1, avoid a large amount of dust covering the surface of the circuit board 7, and prevent the dustproof circuit board 7 from being able to dissipate heat normally, thereby effectively improving the service life of the router.

[0034] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
