Description

Technical Field

[0001] This utility model relates to the technical field of heat dissipation devices for network equipment, and in particular to a detachable multi-channel heat dissipation device for computer network equipment. Background Technology

[0002] Computer network equipment is a specialized hardware device used to connect various servers, PCs, application terminals, and other nodes to form an information and communication network. It includes information network equipment, communication network equipment, and network security equipment. Common network equipment includes switches, routers, firewalls, bridges, hubs, gateways, VPN servers, network interface cards (NICs), wireless access points (WAPs), modems, 5G base stations, optical transceivers, fiber optic transceivers, and optical cables. However, network equipment generates a lot of heat during operation. If these devices are placed in a concentrated manner, the heat is not easily dissipated, which can easily lead to heat accumulation and localized temperature increases, thus affecting the use of the network equipment.

[0003] Therefore, existing server racks generally increase the distance between network devices to allow heat to be better dispersed into the air. However, this structure can accommodate fewer network devices, so multiple server racks are needed to arrange the network devices, which requires a large amount of space. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a compact, detachable multi-channel heat dissipation device that can simultaneously dissipate heat from multiple computer network devices.

[0005] The technical solution adopted by this utility model is as follows: This utility model includes a base, the base having a heat dissipation cavity, and air inlets communicating with the heat dissipation cavity on both sides of the base; two sets of heat dissipation components, each heat dissipation component communicating with a corresponding air inlet; each heat dissipation component including a heat dissipation seat detachably connected to the base, several heat dissipation fans fixedly connected to the heat dissipation seat, and a flow equalization plate guided and connected to the heat dissipation seat; an air outlet connected to the air inlet is formed on the upper part of the heat dissipation seat; a buffer cavity for reducing airflow speed is formed on the inner side of the heat dissipation seat; and a mounting frame detachably connected to the upper part of the base.

[0006] Furthermore, the heat sink has several mounting ports at equal intervals on the side away from the air outlet, and each mounting port is fixedly connected to the corresponding heat sink fan. Several baffles are equally spaced in the buffer cavity, and each baffle is located on one side of the corresponding mounting port. A partition plate is formed between two adjacent mounting ports to prevent airflow turbulence.

[0007] Furthermore, the left and right side walls of the buffer cavity are provided with sliders that cooperate with the flow equalization plate. The sliders are located between the air outlet and the baffle plate. The upper surface of the heat sink is formed with a slot that cooperates with the flow equalization plate.

[0008] Furthermore, the cooling fan includes a drive fan fixedly connected to the heat sink, a fixed frame fixedly connected to one side of the drive fan, and a plurality of cooling fins equally spaced within the fixed frame. The upper part of the fixed frame forms two connecting pipes for connecting refrigerant, and the connecting pipes are connected to the cooling fins.

[0009] Furthermore, a heat insulation plate is provided between each pair of adjacent cooling fins.

[0010] Furthermore, the flow equalization plate has a plurality of flow equalization holes for airflow to pass through, and a handle is formed on the upper part of the flow equalization plate.

[0011] Furthermore, the lower surface of the mounting frame is provided with a plurality of fixing brackets for supporting network devices at equal intervals, and each fixing bracket is provided with a ventilation hole at its bottom. The upper surface of the mounting frame is provided with a positioning block for positioning the network device on the side corresponding to the opening of the corresponding fixing bracket. Limiting blocks are formed on both sides of the mounting frame to cooperate with the upper guide of the base.

[0012] Furthermore, guide blocks are formed on both sides of the base, and the guide blocks have openings for guiding and connecting the heat sink. A first magnetic element is disposed in the opening.

[0013] Furthermore, two connecting blocks are provided below the heat sink, and a positioning post is formed in each connecting block. Each positioning post is guided and engaged with the corresponding opening. A second magnetic element is provided between the two positioning posts to magnetically engage with the first magnetic element.

[0014] The beneficial effects of this utility model are as follows: The base of this utility model is connected to heat dissipation components on both sides. Cold air enters the heat dissipation cavity from both sides from top to bottom, thereby removing the heat generated by the network equipment, reducing environmental problems in the operation of the network equipment, and providing operational stability. The heat dissipation components adopt a drive fan and condenser fin structure. After the external air is drawn in by the drive fan, the condenser fins absorb the heat in the air, making the air temperature entering the buffer cavity lower than the room temperature. Inside the buffer cavity, a baffle plate is set at the output end of the heat dissipation fan. The airflow blown out by the heat dissipation fan collides with the baffle plate, reducing the airflow speed. The inclined angle structure of the baffle plate is used to guide the airflow into the direction of the flow equalization plate, avoiding the formation of reverse airflow after the airflow collides with the baffle plate, which would affect the airflow efficiency.

[0030] like Figures 1 to 7As shown, in this embodiment, the present invention includes a base 1, the base 1 having a heat dissipation cavity 11, and air inlets 12 communicating with the heat dissipation cavity 11 on both sides of the base 1, two sets of heat dissipation components 2, each heat dissipation component 2 communicating with a corresponding air inlet 12, each heat dissipation component 2 including a heat dissipation seat 21 detachably connected to the base 1, a plurality of heat dissipation fans 22 fixedly connected to the heat dissipation seat 21, and a flow equalization plate 23 guiding and connected to the heat dissipation seat 21, an air outlet 24 connected to the air inlet 12 being formed on the upper part of the heat dissipation seat 21, a buffer cavity 25 for reducing airflow speed being formed on the inner side of the heat dissipation seat 21, and a mounting frame 3 detachably connected to the upper part of the base 1.

[0031] Specifically, the upper edge of the base 1 is provided with multiple grooves. When the mounting frame 3 is inserted, it is quickly positioned by the limiting block 34 cooperating with the grooves. The air inlet 12 forms a slot that is positioned and cooperates with the air outlet 24, so that the base 1 and the heat dissipation component 2 can be tightly fitted to reduce the leakage of cold air and improve the cooling effect. One side of the base 1 is provided with an outlet for discharging hot air, and the other side of the base 1 is provided with a cable hole for connecting the connection line.

[0032] The base 1 is connected to heat dissipation components 2 on both sides. Cold air enters the heat dissipation cavity 11 from both sides from top to bottom, thereby removing the heat generated by the network equipment, reducing environmental problems during network equipment operation, and providing operational stability. The heat dissipation components 2 adopt a drive fan 221 and a condenser fin structure. After the external air is drawn in by the drive fan 221, the condenser fins absorb the heat in the air, making the air temperature entering the buffer cavity 25 lower than the room temperature. Inside the buffer cavity 25, the airflow blown out by the heat dissipation fan 22 is blown by a baffle 27 set at the output end of the heat dissipation fan 22, which reduces the airflow speed. The inclined angle structure of the baffle 27 is used to guide the airflow into the direction of the flow equalization plate 23, avoiding the formation of reverse airflow after the airflow hits the baffle 27, which would affect the airflow efficiency.

[0033] like Figures 4 to 7 As shown, in this embodiment, the heat sink 21 has a plurality of mounting ports 26 at equal intervals on the side away from the air outlet 24. Each mounting port 26 is fixedly connected to the corresponding heat sink 22. A plurality of baffles 27 are arranged at equal intervals in the buffer cavity 25. Each baffle 27 is arranged on one side of the corresponding mounting port 26. A partition plate 28 is formed between two adjacent mounting ports 26 to prevent airflow turbulence.

[0034] Specifically, the baffle 27 has an inclined surface on the side near the cooling fan 22. The inclined surface is used to guide the airflow blown out by the cooling fan 22 toward the direction of the flow equalization plate 23, reduce airflow accumulation, and improve airflow efficiency. The partition plate 28 is used to separate the airflow of the two cooling fans 22, reducing the occurrence of gas turbulence caused by airflow collision.

[0035] like Figures 6 to 7 As shown, in this embodiment, the left and right side walls of the buffer cavity 25 are provided with sliders 29 that guide and cooperate with the flow equalization plate 23. The sliders 29 are disposed between the air outlet 24 and the baffle plate 27. The upper surface of the heat sink 21 is formed with a slot that guides and cooperates with the flow equalization plate 23.

[0036] Specifically, slider 29 is used to guide the flow equalization plate 23 into place, improving installation efficiency.

[0037] like Figure 8 As shown, in this embodiment, the cooling fan 22 includes a drive fan 221 fixedly connected to the heat sink 21, a fixed frame 222 fixedly connected to one side of the drive fan 221, and a plurality of cooling fins 223 equally spaced within the fixed frame 222. The upper part of the fixed frame 222 forms two connecting pipes 225 for connecting refrigerant, and the connecting pipes 225 are connected to the cooling fins 223.

[0038] Specifically, the drive fan 221 is an electric fan. A protective net is formed on the side of the drive fan 221 that is in contact with the external environment to prevent damage to the drive fan 221 caused by external collisions. The connecting pipe 225 is connected to the external refrigerant mechanism, and the cooling fins 223 are connected to the connecting pipe 225. The refrigerant pipe absorbs the heat from the cooling fins 223 and carries it to the refrigerant mechanism, so that the cooling fan 22 always blows out cold air below room temperature, resulting in high heat dissipation efficiency.

[0039] like Figure 9 As shown, in this embodiment, a heat insulation plate 224 is provided between each of the two adjacent cooling fins 223.

[0040] like Figure 11 As shown, in this embodiment, the flow equalization plate 23 is formed with a plurality of flow equalization holes 231 for airflow to pass through, and a handle 232 is formed on the upper part of the flow equalization plate 23.

[0041] Specifically, the flow equalization hole 231 is used to further reduce the flow speed of cold air, so that the cold air flows out from the outlet 24 at a low speed, and the cold air absorbs and carries away more heat.

[0042] like Figure 10As shown, in this embodiment, the lower surface of the mounting frame 3 is provided with a plurality of fixing frames 31 for supporting network devices at equal intervals. Each fixing frame 31 has a ventilation hole 32 at its bottom. The upper surface of the mounting frame 3 is provided with a positioning block 33 for positioning the network device on the side corresponding to the opening of the corresponding fixing frame 31. Limiting blocks 34 are formed on both sides of the mounting frame 3 to cooperate with the upper guide of the base 1.

[0043] Specifically, there is a gap between each pair of fixed brackets 31 for gas flow. When cold air flows out, it carries away heat from the gap and reduces the temperature inside the heat dissipation cavity 11. The positioning block 33 has a positioning groove. The positioning block 33 is used for guiding and positioning when network devices are placed in, thereby improving installation efficiency.

[0044] like Figure 3 As shown, in this embodiment, guide blocks 13 are formed on both sides of the base 1, and the guide blocks 13 are formed with openings 14 for guiding and connecting the heat sink 21. A first magnetic element 15 is provided in the openings 14.

[0045] Specifically, the design of guide block 13 and opening 14 simplifies the installation method of heat sink 21 and improves installation efficiency. The first magnetic component 15 cooperates with the second magnetic component 213 to improve connection stability.

[0046] like Figure 7 As shown, in this embodiment, two connecting blocks 211 are provided below the heat sink 21. Each connecting block 211 has a positioning post 212 formed therein. Each positioning post 212 is guided and engaged with the corresponding opening 14. A second magnetic element 213 is provided between the two positioning posts 212 and is magnetically engaged with the first magnetic element 15.

[0047] Specifically, the positioning post 212 is connected with the opening 14 to improve connection stability, facilitate daily installation and disassembly, and improve the efficiency of network equipment operation and maintenance.

[0048] The working principle of this utility model:

[0049] Before use, the staff fixes the network equipment on the mounting frame 3. The mounting frame 3 is fixed to the groove on the upper edge of the base 1 by the limiting component. Then the heat dissipation components 2 on both sides are installed. The positioning post 212 of the heat dissipation component 2 is guided and cooperated with the opening 14. The connecting block 211 is guided and connected with the guide block 13 to complete the fixation. The first magnetic component 15 and the second magnetic component 213 are magnetically attached to each other to improve the connection stability.

[0050] During heat dissipation, external air is drawn in by the drive fan 221, and the condenser fins absorb heat from the air, making the air temperature entering the buffer chamber 25 lower than the room temperature. Inside the buffer chamber 25, the airflow blown out by the fan 22 hits the baffle 27 at the output end of the cooling fan 22, reducing the airflow speed. The inclined angle structure of the baffle 27 is used to guide the airflow to flow towards the flow equalization plate 23. The cold air passes through the flow equalization plate 23, reducing the airflow speed, and enters the heat dissipation chamber 11 along the air outlet 24. The cold air covers the heat dissipation equipment from top to bottom, carries away heat from the gap between the two network devices, and reduces the temperature inside the heat dissipation chamber 11. The hot air flows out from the exhaust port on one side of the base 1.

[0051] Although the embodiments of this utility model are described with reference to actual solutions, they do not constitute a limitation on the meaning of this utility model. For those skilled in the art, modifications to the implementation schemes and combinations with other schemes based on this specification are obvious.
