Description

Technical Field

[0001] The utility model relates to the technical field of switches, in particular to a heat dissipation device for a computer network switch. Background Art

[0002] A computer network switch is a device that expands a network and provides more connection ports in a sub-network to connect more computers.

[0003] Currently, computer network switches will generate a lot of heat during long-term operation. Since the heat dissipation device inside the switch cannot completely discharge the heat generated inside the body, it will cause damage to the internal components after long-term operation.

[0004] A computer network switch heat dissipation device is disclosed in a patent document with publication number CN214102183U. The device places the switch on the surface of the radiator, rotates the threaded rod, and moves forward after the thread inside the fixed block rotates, thereby driving the fixed plate to move forward to fit the switch, so that the switch is fixed between the two fixed plates and fixed on the surface of the radiator, thereby utilizing the radiator to dissipate heat from the outside of the switch.

[0005] However, the heat dissipation device of the computer network switch can only dissipate heat outside the switch, and a large amount of heat inside the switch cannot be discharged in time, resulting in poor heat dissipation effect. Utility Model Content

[0006] The purpose of the utility model is to provide a heat dissipation device for a computer network switch to solve the problems raised in the above background technology.

[0007] To achieve the above purpose, the utility model provides the following technical solutions: a computer network switch heat dissipation device, including a switch and an interface opened on the front of the switch, a through slot is opened on one side of the switch, and a heat dissipation device is arranged inside the through slot.

[0008] The heat dissipation device comprises a flow mechanism and a circulation mechanism, and the interior of the through slot is divided into a flow cavity and an upper and lower part of the heat dissipation cavity.

[0009] The flow mechanism includes a partition plate 1, a push plate and a curved plate. The partition plate 1 is fixedly installed on the bottom of the inner wall of the flow chamber, the push plate is slidably connected to the upper surface of the partition plate 1, and the curved plate is fixedly connected to both ends of the push plate.

[0010] The circulation mechanism includes partition plate 2, a baffle, a fan, a telescopic spring, a slide plate and a magnetic plate. The partition plate 2 is fixedly installed on the bottom of the inner wall of the through slot. The baffle and the fan are respectively fixedly installed on the two ends of the through slot. The telescopic spring is fixedly connected to one side of the baffle. The slide plate is fixedly connected to the end of the telescopic spring away from the baffle. The magnetic plate is fixedly connected to the top of the slide plate.

[0011] Preferably, there are two partition plates 1, which are separated by partition plate 2 in the middle, a magnet is installed inside the push plate, and the contact part between partition plate 1 and partition plate 2 is coated with sealant.

[0012] Preferably, a slide groove is provided on the upper surface of the switch, a metal heat sink is fixedly connected to the interior of the slide groove, and the bottom of the metal heat sink extends to the interior of the flow cavity and contacts with the coolant.

[0013] Preferably, the fan is electrically connected to an internal power supply of the switch, the telescopic spring is a light spring, and the magnetic plate is made of a strong magnetic block.

[0014] Preferably, a protective plate in contact with the metal heat sink is fixedly mounted on the top of the switch, and the protective plate can be in contact with the metal heat sink to accelerate heat transfer.

[0015] Preferably, balance boards are fixedly mounted on both sides of the switch, and an LED light is fixedly mounted on the top of the switch. The LED light can emit light at night to prevent collisions due to poor visibility at night.

[0016] Preferably, a mounting frame is fixedly connected to the bottom of the switch, a bolt hole is provided on the surface of the mounting frame, and a reinforcing rib is fixedly connected to one side of the mounting frame. The bolt hole facilitates the connection and fixation of the mounting frame to the wall, and the reinforcing rib can enhance the bearing capacity of the mounting frame.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. In the heat dissipation device for computer network switches, the magnetic plate attracts the push plate to slide inside the flow cavity, thereby driving the curved plates on both sides to move and push the coolant to flow. After the coolant contacts the metal heat sink, it transfers heat to the metal heat sink. Because one side of the metal heat sink contacts the air, the effect of rapid heat dissipation can be achieved.

[0019] 2. After the telescopic spring is stretched to the maximum elongation, the heat dissipation device of the computer network switch will shrink under the action of its own restoring force, and at the same time pull the magnetic plate to reset, thereby attracting the push plate to slide in the opposite direction inside the flow cavity. Under the action of the thrust caused by the fan and the restoring force of the telescopic spring itself, the push plate will make a small range of reciprocating movement inside the flow cavity, thereby continuously pushing the coolant to flow and contact with the metal heat sink, further enhancing the heat dissipation effect.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-Figure 7 , the utility model provides a technical solution:

[0030] Embodiment 1:

[0031] A heat dissipation device for a computer network switch comprises a switch 1 and an interface 2 provided on the front of the switch 1, wherein a through slot 4 is provided on one side of the switch 1, and a heat dissipation device is provided inside the through slot 4.

[0032] The heat dissipation device comprises a flow mechanism and a circulation mechanism, and the interior of the through slot 4 is divided into two parts, namely, a flow cavity 401 and an upper and lower part of a heat dissipation cavity 405 .

[0033] The flow mechanism includes a partition 402, a push plate 403 and a curved plate 404. The partition 402 is fixedly installed at the bottom of the inner wall of the flow chamber 401. The push plate 403 is slidably connected to the upper surface of the partition 402. The curved plate 404 is fixedly connected to both ends of the push plate 403. The partition 402 is divided into two, which are separated by a partition 406 in the middle. A magnet is installed inside the push plate 403, and the contact part between the partition 402 and the partition 406 is coated with sealant.

[0034] The circulation mechanism includes a partition plate 2 406, a baffle 407, a fan 408, a telescopic spring 409, a slide plate 410 and a magnetic plate 411. The partition plate 2 406 is fixedly installed at the bottom of the inner wall of the through slot 4. The baffle 407 and the fan 408 are respectively fixedly installed at both ends of the through slot 4. The telescopic spring 409 is fixedly connected to one side of the baffle 407. The slide plate 410 is fixedly connected to the end of the telescopic spring 409 away from the baffle 407. The magnetic plate 411 is fixedly connected to the top of the slide plate 410. The interior of the flow chamber 401 is filled with a coolant, which is water. A slide groove is provided on the upper surface of the switch 1. A metal heat sink 412 is fixedly connected to the interior of the slide groove. The bottom of the metal heat sink 412 extends to the interior of the flow chamber 401 and contacts with the coolant. The fan 408 is connected to the switch 1. The internal power supply of machine 1 is electrically connected, the telescopic spring 409 is a lightweight spring, the magnetic plate 411 is made of a strong magnetic block, the magnetic plate 411 and the side close to the push plate 403 attract each other, and a protective plate 413 in contact with the metal heat sink 412 is fixedly installed on the top of the switch 1. After the telescopic spring 409 is stretched to the maximum elongation, it will shrink under the action of its own restoring force, and at the same time pull the magnetic plate 411 to reset, thereby attracting the push plate 403 to slide in the opposite direction inside the flow chamber 401. Under the thrust caused by the fan 408 and the restoring force of the telescopic spring 409 itself, the push plate 403 will make a small range of reciprocating movement inside the flow chamber 401, thereby continuously promoting the flow of coolant and contacting with the metal heat sink 412, further enhancing the heat dissipation effect.

[0035] Embodiment 2:

[0036] On the basis of the first embodiment, a balance board 3 is fixedly installed on both sides of the switch 1, and an LED lamp 5 is fixedly installed on the top of the switch 1. The balance board 3 can facilitate the placement of the switch 1 and prevent it from tipping over or being unstable. The LED lamp 5 is electrically connected to the internal power supply of the switch 1 and can emit light at night to prevent collisions due to poor visibility at night.

[0037] A mounting frame 6 is fixedly connected to the bottom of the switch 1 . Bolt holes are provided on the surface of the mounting frame 6 . A reinforcing rib 601 is fixedly connected to one side of the mounting frame 6 . The mounting frame 6 can conveniently fix the switch 1 .

[0038] Working principle: When the switch is working, the heat generated will be absorbed by the coolant. After the power is turned on, the fan 408 starts, and the fan 408 accelerates the air flow speed inside the heat dissipation cavity 405, so that the air blows the slide plate 410 to slide inside the heat dissipation cavity 405. During the sliding process, the slide plate 410 drives the magnetic plate 411 to slide to the side away from the fan 408, and at the same time stretches the telescopic spring 409. During the sliding process of the magnetic plate 411, because the magnetic plate 411 and the side close to the push plate 403 attract each other, the magnetic plate 411 will attract the push plate 403 to slide inside the flow cavity 401, thereby driving the curved plates 404 on both sides to move and promote the flow of coolant. After the coolant contacts the metal heat dissipation plate 412, it will transfer the heat to the metal heat dissipation plate 412. Because one side of the metal heat dissipation plate 412 is in contact with the air, the effect of rapid heat dissipation can be achieved.
