DETAILED DESCRIPTION

[0024] See also Figure 1-Figure 7 , an overheating prevention component for switch cabinet equipment, comprising a jetting member 1 arranged inside the switch cabinet, one end of the jetting member 1 extending to the outside of the switch cabinet and fixedly connected to a shunt pipe 2, and one side of the shunt pipe 2 is fixedly connected to a cooling box 4:

[0025] Furthermore, the cooling box 4 includes a first box body 401, one side of the first box body 401 is fixedly connected to one side of the switch cabinet, a condenser 402 is fixedly connected inside the first box body 401, an air intake pipe 403 is fixedly connected to the top of the condenser 402, one end of the air intake pipe 403 extends to the top of the first box body 401 and is fixedly connected to the top of the diversion pipe 2, an exhaust pipe 404 is fixedly connected to the bottom of the condenser 402, one end of the exhaust pipe 404 extends to the outside of the first box body 401 and is fixedly connected to the filter box 5.

[0026] When the temperature inside the switch cabinet is too high, the operator can start the fan 502, and the fan 502 introduces the air in the environment into the outlet pipe 503 and transports it to the inside of the second box 501. The first filter plate 504 and the second filter plate 505 arranged inside the second box 501 can filter the air, and the gas filtered by the first filter plate 504 and the second filter plate 505 enters the inside of the condenser pipe 402 along the exhaust pipe 404. The operator can pre-fix the liquid inlet pipe of the first box 401 with the output end of the external circulating cooling device, and fix the liquid outlet pipe with the input end of the external circulating cooling device, so as to facilitate the inside of the first box 401. The coolant is continuously delivered. When the gas passes through the condenser 402, the coolant inside the first box 401 can cool the air. The cooled gas is delivered to the inside of the shunt pipe 2 along the air inlet pipe 403. The cold air delivered to the inside of the shunt pipe 2 can be delivered to the inside of the jet pipe 101 along the multiple connecting pipes 103 and blown to the heating electrical components inside the switch cabinet through the nozzle 102, so as to cool down the electrical components inside the switch cabinet in time. The equipment combines multiple functions such as gas circulation, heat exchange and air purification, realizes effective heat dissipation and environmental cleaning inside the switch cabinet, and helps to improve the stability of equipment operation and extend the service life of the equipment.

[0027] Furthermore, the jet component 1 includes a jet pipe 101 arranged inside the switch cabinet, a plurality of nozzles 102 are fixedly connected to one side of the jet pipe 101, a plurality of connecting pipes 103 are fixedly connected to the rear side of the jet pipe 101, and one end of the connecting pipe 103 extends to the outside of the switch cabinet and is fixedly connected to one side of the diversion pipe 2.

[0028] The cold air can be introduced into the jet pipe 101 through the connecting pipe 103, and then dispersedly sprayed out through the nozzle 102 to form an effective air circulation system. The nozzle 102 is distributed at a specific angle and layout, which can evenly spray the cold air to the heating parts inside the switch cabinet to enhance the heat dissipation effect. At the same time, it can also promote the circulation of air in the cabinet and reduce the generation of local hot spots.

[0029] Furthermore, a fixing plate 104 is fixedly connected to the top and bottom of the jet pipe 101, and the fixing plate 104 is fixedly connected to one side of the inner wall of the switch cabinet. The front and rear end surfaces of the shunt pipe 2 are fixedly connected to a first mounting frame 3, and the first mounting frame 3 is fixedly connected to one side of the switch cabinet.

[0030] The fixing plate 104 is tightly fixed to one side of the inner wall of the switch cabinet, which not only ensures that the jet pipe 101 will not be displaced or loosened due to gas pressure or vibration during operation, but also facilitates the precise arrangement of the positions of the jet pipe 101 and its nozzle 102, so that they can be directed to the key heating area according to the best design scheme, ensuring the optimization of the heat dissipation effect.

[0031] Furthermore, the filter box 5 includes a second box body 501, one side of the second box body 501 is fixedly connected to one side of the first box body 401, the top of the second box body 501 is fixedly connected to a fan 502, the air outlet end of the fan 502 is fixedly connected to an air outlet pipe 503, and one end of the air outlet pipe 503 is fixedly connected to the top of the second box body 501.

[0032] This device combines the fan 502 and the filter medium, which accelerates the flow rate of the gas on the one hand, and effectively filters out dust, moisture and other harmful substances in the gas on the other hand, ensuring that the gas returning to the inside of the switch cabinet is both cool and clean, which is of great significance to the efficient and stable operation of electrical equipment and to extending the life of the equipment.

[0033] Furthermore, the second mounting bracket 6 is fixedly connected to the front and rear sides of the surface of the first box body 401 , a protective door 506 is rotatably connected to one side of the second box body 501 , and a handle 507 is fixedly connected to one side of the protective door 506 .

[0034] The second mounting frame 6 enhances the overall structural stability and bearing capacity of the first box body 401, ensuring that it remains stable during installation and operation. The operator can conveniently check, maintain or clean the interior by opening and closing the protective door 506. A handle 507 is also fixedly connected to one side of the protective door 506. This humanized design enables the operator to easily operate the protective door 506, thereby improving the convenience and safety of equipment use.

[0035] Furthermore, a first filter plate 504 and a second filter plate 505 are fixedly connected inside the second box body 501 , and a mesh diameter of the first filter plate 504 is greater than a mesh diameter of the second filter plate 505 .

[0036] The first filter plate 504 is usually used to capture and filter out larger particles or impurities, because its mesh is coarse, allowing most of the gas to pass freely while blocking larger particles. The second filter plate 505 provides a more refined filtering level, and its smaller mesh diameter can capture small particles that the first filter plate 504 fails to intercept, and even some tiny water droplets or oil mist, to ensure that the gas that is finally discharged or circulated back to the switch cabinet reaches the ideal cleanliness.

[0037] Furthermore, the top and bottom of the first box body 401 are respectively fixedly connected with a liquid inlet pipe and a liquid outlet pipe.

[0038] In this process, the cooling liquid enters the first box body 401 through the liquid inlet pipe, and cools down the high-temperature gas around the condenser 402 through heat exchange. The heated liquid then flows out through the liquid outlet pipe and enters the circulating cooling equipment to be cooled again. This closed-loop cooling system has the advantages of high efficiency and energy saving, and can continuously provide cooling effect for the switch cabinet, effectively preventing failures of internal electrical equipment caused by overheating, and ensuring the stable operation of power equipment.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
