Description

Technical Field

[0001] This application relates to the field of withdrawable switchgear technology, and more specifically to a heat-dissipating low-voltage withdrawable switchgear. Background Technology

[0002] Low-voltage withdrawable switchgear is a type of power distribution equipment widely used in power plants, petrochemical, metallurgical, and light textile industries. Its average temperature within 24 hours must not exceed +35℃. However, existing low-voltage withdrawable switchgear has poor heat dissipation, and prolonged high-temperature operation can easily affect its working efficiency and service life.

[0003] In view of this, the inventor has designed a heat-dissipating low-voltage withdrawable switch cabinet. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a heat-dissipating low-voltage withdrawable switch cabinet. Its advantages are that it can monitor the temperature inside the cabinet and drawers at all times, and when the temperature inside the cabinet and drawers is too high, it can cool down the cabinet and drawers by compressing airflow. The compressed cold air then cools down the inside of the cabinet and drawers, thereby achieving intelligent control and efficient cooling.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat-dissipating low-voltage withdrawable switch cabinet, comprising a cabinet body and a drawer. An air inlet and an air outlet are respectively provided at the lower and upper rear ends of the cabinet body. An air guide port is provided at the rear of the drawer, and an overflow port is provided on the side of the drawer. A dustproof cooling device connected to the air inlet is provided inside the cabinet body. A main air guide pipe and a heat dissipation main pipe are provided at the air outlet of the dustproof cooling device. Several secondary air guide pipes connected to corresponding air guide ports are provided on the main air guide pipe. A compression cooling device is provided at each of the secondary air guide pipes. A draft fan is provided on both the air outlet and the overflow port. Several heat dissipation components and compression cooling devices are arranged sequentially from bottom to top inside the cabinet body. Temperature sensors are provided on both the cabinet body and the drawer. A controller is provided inside the cabinet body.

[0006] By adopting the above technical solution, when the temperature sensors located on the cabinet and drawers detect that the temperature is too high, the controller controls the dustproof cooling device to operate, so that the outside air is quickly drawn in from the air inlet, and after dustproof treatment, strong air is delivered from the main air guide pipe and the heat dissipation main pipe. The exhaust fans located on the air outlet and the overflow vent also operate under the control of the controller. The strong air in the main air guide pipe enters the air guide vent through each secondary air guide pipe, and is compressed and cooled by the air compression cooling device on the secondary air guide pipe. The hot air in the drawer is exhausted to the outside through the exhaust fan of the overflow vent, which can effectively cool the inside of the drawer quickly. The strong air in the heat dissipation main pipe blows into the cabinet and passes through several arranged heat dissipation components and compression cooling devices from bottom to top. The hot air in the cabinet is exhausted to the outside through the exhaust fan of the air outlet, which can effectively cool the inside of the cabinet quickly.

[0007] In summary, the above-mentioned system monitors temperature using temperature sensors and controllers, and uses controllers, dustproof cooling devices, main air ducts, main heat dissipation ducts, secondary air ducts, and exhaust fans to circulate and exhaust hot air from inside the drawers and cabinets. Furthermore, compression cooling devices and heat dissipation components accelerate the cooling of the drawers and cabinets, thereby achieving the purpose of intelligent control and efficient cooling.

[0008] The present invention is further configured as follows: the dustproof cooling device includes a dustproof duct installed on the cabinet and connected to the air inlet, a dustproof net installed at the end of the dustproof duct near the air inlet, a honeycomb activated carbon dust adsorption component installed at the end of the dustproof duct away from the air inlet, and a powerful blower installed at the end of the dustproof duct near the honeycomb activated carbon dust adsorption component.

[0009] By adopting the above technical solution, when the dustproof cooling device draws air through the air inlet, the controller issues a command to the powerful blower, causing the powerful blower to operate and draw the air outside the air inlet into the dustproof duct. The outside air is drawn into the dustproof duct by the suction of the powerful blower, forming a strong airflow. Then, after being cleaned by the dustproof net and the honeycomb activated carbon dust adsorption component, it flows through the corresponding air guide tube and heat dissipation tube, thereby cooling the drawer and cabinet.

[0010] The present invention is further configured such that: the compression cooling device includes a support frame and a plurality of bucket-shaped compression pipes disposed on the same plane as the support frame, wherein the end of the bucket-shaped compression pipe with a larger opening is the air inlet end and the end of the bucket-shaped compression pipe with a smaller opening is the air outlet end.

[0011] By adopting the above technical solution, when the airflow enters rapidly from the larger end of the bucket-shaped compression pipe and flows out from the smaller end of its opening, the airflow can be cooled by compression, thereby quickly cooling the inside of the drawer and cabinet.

[0012] The present invention is further configured such that the plurality of bucket-shaped compression tubes on the support frame are provided in two layers.

[0013] By adopting the above technical solution, the support frame has two layers of bucket-shaped compression tubes, which can further increase the cooling effect.

[0014] The present invention is further configured such that the heat dissipation component is a plurality of heat dissipation grilles at the junction with the surface of the cabinet.

[0015] By adopting the above technical solution, the heat dissipation grille can absorb the heat of the electronic components inside the cabinet and cool it down with cold air, which greatly accelerates the cooling of the cabinet.

[0016] The present invention is further configured such that dustproof nets are provided on both the air outlet and the overflow outlet.

[0017] In summary, this utility model has the following advantages:

[0018] 1. Temperature sensors and controllers monitor the temperature, and the controller, dustproof cooling device, main air duct, main heat dissipation duct, secondary air duct, and exhaust fan circulate and exhaust the hot air inside the drawers and cabinets. The compression cooling device and heat dissipation components accelerate the cooling of the drawers and cabinets, thereby achieving intelligent control and efficient cooling.

[0019] 2. When the dustproof cooling device draws air through the air inlet, the controller issues a command to the powerful blower, causing the blower to operate and draw the air outside the air inlet into the dustproof duct. The outside air is drawn into the dustproof duct by the suction of the blower, forming a strong airflow. Then, after passing through the dustproof mesh and honeycomb activated carbon dust adsorption components for dust removal, it flows through the corresponding air guide pipe and heat dissipation pipe, thereby cooling the drawers and cabinets.

[0020] 3. When the airflow enters rapidly from the larger end of the funnel-shaped compressor pipe and flows out from the smaller end of its opening, the airflow is compressed and cooled, thus quickly cooling the inside of the drawer and cabinet. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] A type of heat-dissipating low-voltage withdrawable switchgear, such as Figure 1 , 2 As shown, the cabinet includes a cabinet body 1 and a drawer 2. The lower and upper rear ends of the cabinet body 1 are respectively provided with an air inlet 3 and an air outlet 4. The rear of the drawer 2 is provided with an air guide 5, and the side of the drawer 2 is provided with an air overflow 6. A dustproof cooling device connected to the air inlet 3 is installed inside the cabinet body 1. A main air guide 7 and a heat dissipation main 8 are installed on the air outlet of the dustproof cooling device. The opening of the heat dissipation main 8 faces the upper end of the cabinet body 1. Several secondary air guide pipes 9 connected to the corresponding air guide 5 are installed on the main air guide 7. A compression cooling device is installed at the secondary air guide pipes 9. A fan 10 is installed on both the air outlet 4 and the air overflow 6. Several heat dissipation components and compression cooling devices are arranged and installed from bottom to top inside the cabinet body 1. Temperature sensors 11 are installed on both the cabinet body 1 and the drawer 2. A controller 12 is installed inside the cabinet body 1. Dustproof screens 13 are installed on both the air outlet 4 and the air overflow 6.

[0026] like Figure 1 , 2 As shown, the dustproof cooling device includes a dustproof duct 14 installed on the cabinet 1 and connected to the air inlet, a dustproof net 13 installed at the end of the dustproof duct 14 near the air inlet, a honeycomb activated carbon dust adsorbent 15 installed at the end of the dustproof duct 14 away from the air inlet, and a powerful blower 16 installed at the end of the dustproof duct 14 near the honeycomb activated carbon dust adsorbent 15. When the dustproof cooling device draws air through the air inlet 3, the controller 12 issues a command to the powerful blower 16, causing the powerful blower 16 to operate and draw the air outside the air inlet 3 into the dustproof duct 14. The outside air forms a strong airflow through the suction of the powerful blower 16 and enters the dustproof duct 14. Then, after being dusted by the dustproof net 13 and the honeycomb activated carbon dust adsorbent 15, it flows through the corresponding air guide 7 and heat dissipation 8, thereby cooling the drawer 2 and the cabinet 1.

[0027] like Figure 1 , 2 As shown, the compression cooling device includes a support frame 17 and several funnel-shaped compression pipes 18 installed on the same plane as the support frame 17. The end of the funnel-shaped compression pipe 18 with a larger opening is the air inlet, and the end with a smaller opening is the air outlet. When the airflow rapidly enters from the larger end of the funnel-shaped compression pipe 18 and flows out from its smaller opening, the airflow is compressed and cooled, thereby rapidly cooling the inside of the drawer 2 and the cabinet 1.

[0028] Furthermore, the support frame 17 has several bucket-shaped compression tubes 18 arranged in two layers, which can further increase the cooling effect.

[0029] like Figure 1 , 2 As shown, the heat dissipation component consists of several heat dissipation grilles 19 that are in contact with the surface of the cabinet 1. The heat dissipation grilles 19 can absorb the heat of the electronic components inside the cabinet 1 and cool it down with cold air, which greatly accelerates the cooling of the inside of the cabinet 1.

[0030] The working process and beneficial effects of this utility model are as follows:

[0031] When the temperature sensor 11 located on the cabinet 1 and drawer 2 detects that the temperature is too high, the controller 12 controls the dustproof cooling device to operate, so that the outside air is quickly drawn in from the air inlet 3, and after dustproof treatment, strong air is delivered from the main air guide 7 and the heat dissipation main 8. The exhaust fan 10 located on the air outlet 4 and the overflow vent 6 also operates under the control of the controller 12. The strong air in the main air guide 7 enters the air guide vent 5 through each secondary air guide duct 9, and is compressed and cooled by the air compression cooling device on the secondary air guide duct 9. The hot air in the drawer 2 is exhausted to the outside through the exhaust fan 10 of the overflow vent 6, which can effectively cool the inside of the drawer 2 quickly. The strong air in the heat dissipation main 8 blows into the inside of the cabinet 1, and passes through several arranged heat dissipation components and compression cooling devices from bottom to top. The hot air in the cabinet 1 is exhausted to the outside through the exhaust fan 10 of the air outlet 4, which can effectively cool the inside of the cabinet 1 quickly.

[0032] In summary, the above-mentioned temperature sensor and controller 12 monitor the temperature, and the controller 12, dustproof cooling device, main air duct 7, heat dissipation main duct 8, secondary air duct 9, and exhaust fan 10 circulate and exhaust the hot air inside the drawer 2 and cabinet 1. The compression cooling device and heat dissipation components accelerate the cooling of the inside of the drawer 2 and cabinet 1, thereby achieving the purpose of intelligent control and efficient cooling.

Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
