[0003] Existing network switches are all equipped with lightning arresters to ensure that the electronic components in the network switches are not damaged when struck by lightning. However, the existing lightning arresters do not have a heat dissipation effect and have limited protection capabilities when encountering high-voltage lightning strikes. The built-in heat dissipation device in the network switch will be disconnected and shut down after being struck by lightning. Its heat dissipation effect is limited, making it difficult to quickly achieve cooling. The electronic components may have their service life affected or even be damaged due to the residual heat from the short circuit.

The lightning arrester 2 is fixedly installed on one side of the switch housing 1, and the connection port 3 is provided on the switch housing 1. The upper end of the switch housing 1 is fixedly installed with the upper shell 4 by bolts, and the upper end of the upper shell 4 is fixedly connected to the coolant tank 1 5. The coolant A coolant tank body 2 7 is provided above the tank body 1 5 , and a heat insulation layer 6 is provided between the coolant tank body 1 5 and the coolant tank body 2 7 . A heat sink 14 is provided on the coolant tank body 1 5 , and a conduit 13 is fixedly connected to the heat sink 14 . A liquid outlet is provided at the lower end of the coolant tank body 2 7 , and a sealing ring 15 is fixedly installed on the liquid outlet of the coolant tank body 2 7 , and an aluminum sheet 16 is fixedly installed on the sealing ring 15 . The coolant tank body 1 5 , the heat insulation layer 6 , the coolant tank body 2 7 , the conduit 13 , the heat sink 14 , the sealing ring 15 and the aluminum sheet 16 together constitute an anti-overheating mechanism.

[0024] See also Figure 2 、 Figure 6 and Figure 7In this embodiment, one end of the heat sink 14 passes through the lower end of the coolant tank body 1 5 and contacts the heating element in the switch housing 1 . The coolant tank body 1 5 is provided with a liquid inlet. The conduit 13 passes through the liquid inlet of the coolant tank body 1 5 and contacts the aluminum sheet 16 at the lower end of the sealing ring 15 . The sealing ring 15 and the aluminum sheet 16 are both provided with holes for bolts to pass through. The liquid outlet of the coolant tank body 1 5 is provided with a threaded hole. The upper end of the coolant tank body 2 7 is threadedly connected to a cover 18. The liquid inlet on the coolant tank body 1 5 is adapted to be connected to the liquid outlet on the coolant tank body 2 7 . The coolant tank body 1 5 and the coolant tank body 2 7 are fixedly connected by a connecting plate 17 .

[0025] See also Figure 3 and Figure 5 In this embodiment, a side fixing seat 8 is fixedly connected to one side of the switch housing 1, and a carbon dioxide storage bottle 9 is provided on the side fixing seat 8. A connecting pipe 10 is provided at the upper end of the carbon dioxide storage bottle 9, and one end of the connecting pipe 10 is fixedly connected to a connector 11. The connector 11 is fixedly installed on the upper end of the coolant tank 2 7. A connecting pipe 2 12 is provided on one side of the carbon dioxide storage bottle 9, and one end of the connecting pipe 2 12 is fixedly connected to a connector 2 19. One end of the connector 2 19 passes through the switch housing 1, and an aluminum sheet 16 is fixedly installed on the connector 2 19 by bolts.

[0026] During use, the lightning arrester 2 is a prior art device. When the switch housing 1 is struck by lightning, it can effectively prevent damage to the electronic components in the switch housing 1. When encountering the above situation, the high voltage generated by the lightning strike is transmitted to the aluminum sheet 16 at the lower end of the outlet of the coolant tank 2 7 through the conduit 13. The aluminum sheet 16 is broken down by the high voltage, and the coolant in the coolant tank 2 7 flows into the coolant tank 1 5. After the coolant contacts the heat sink 14 in the coolant tank 1 5, the heat dissipation effect of the heat sink 14 is enhanced, so that the heat of the electronic components can be dissipated. The high-pressure gas in the carbon dioxide storage bottle 9 is quickly dispersed, and is injected into the coolant tank body 2 7 through the connecting pipe 10 and the connecting head 11. Under the action of pressure, the coolant in the coolant tank body 2 7 can be quickly discharged into the coolant tank body 1 5. The aluminum sheet 16 on one side of the connecting head 2 19 is in contact with the ground of the network switch and ruptures at the same time when struck by lightning. The carbon dioxide in the carbon dioxide storage bottle 9 enters the switch housing 1 through the connecting pipe 2 12, thereby reducing the oxygen concentration in the switch housing 1 and preventing the generation of open flames and causing fires.

[0027] Furthermore, after the aluminum sheet 16 is broken, the bolts on the connecting plate 17 and the upper shell 4 are removed, the coolant tank body 2 7 is removed from the coolant tank body 1 5, and a new aluminum sheet 16 is installed on the liquid outlet of the coolant tank body 2 7 by means of bolts. Subsequently, the liquid outlet of the coolant tank body 2 7 is aligned with the liquid inlet of the coolant tank body 1 5, and then the coolant tank body 2 7 is fixedly connected to the coolant tank body 1 5 by means of the connecting plate 17. The sealing cover 18 is opened to replenish the coolant in the coolant tank body 2 7, and a new aluminum sheet 16 is installed on the connector 2 19 by means of bolts. After completing the above steps, the reset of the overheating prevention mechanism is completed. The thermal insulation layer 6 is used to prevent the heat generated in the switch housing 1 from being transferred to the coolant tank body 2 7 during normal use of the network switch, so that when a lightning strike occurs, the coolant in the coolant tank body 2 7 becomes ineffective and cannot achieve a rapid cooling effect.

[0028] Through the above steps, the anti-overheating mechanism does not need power to start. When the circuit breaker is tripped by lightning, the anti-overheating mechanism can still start and operate. When the aluminum sheet 16 in the anti-overheating mechanism is punctured, the coolant in the coolant tank 2 7 can be quickly discharged under the pressurized action of the carbon dioxide storage bottle 9, thereby achieving rapid cooling. At the same time, carbon dioxide enters the switch housing 1, thereby reducing the oxygen concentration in the switch housing 1 and preventing the generation of open flames and thus causing fires. After the aluminum sheet 16 is ruptured, a new aluminum sheet 16 can be installed in the original place and coolant can be added again, thereby completing the reset of the anti-overheating mechanism. The reset cost of the mechanism is low and the operation is simple and convenient.

[0029] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the present invention.
