Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, specifically to an outdoor power distribution cabinet that facilitates heat dissipation. Background Technology

[0002] Distribution cabinets are important electrical devices in power systems used for power distribution, control and protection. They are typically composed of cabinets, switching elements (such as circuit breakers and contactors), protection devices (fuses and residual current devices), and measuring instruments. They can realize functions such as circuit on / off control, overload protection, and short circuit protection, and are widely used in factory workshops, commercial buildings, residential buildings and other scenarios.

[0003] The power distribution cabinet contains various electronic components, which generate heat when they are working. Traditional power distribution cabinets can only passively dissipate the heat through the ventilation openings on both sides. The heat dissipation inside the power distribution cabinet is relatively slow. It can still work normally indoors or in a cool environment. However, for power distribution cabinets installed outdoors, the high temperature during summer can easily cause the electronic components to overheat. This can lead to unstable operation or even direct damage to the electronic components, which needs further development and improvement. Utility Model Content

[0004] The purpose of this utility model is to provide an outdoor power distribution cabinet that facilitates heat dissipation, thereby solving the problem that traditional power distribution cabinets have poor heat dissipation and are prone to damage to the electronic components installed inside.

The air outlets and the output end of the fan are connected to the inside of the wind box. An air distribution plate is provided inside the wind box. A semiconductor cooling chip is provided on the side of the air distribution plate away from the air outlets.

[0006] Furthermore, a moisture-proof base is provided at the bottom of the supporting base plate. The moisture-proof base includes a supporting column fixedly connected to the supporting base plate and a moisture-proof board disposed at the bottom of the supporting column. The moisture-proof board is made of anti-corrosion and waterproof material.

[0007] Furthermore, an arc-shaped protective guide plate is provided on the top of the power distribution cabinet body.

[0008] Furthermore, a water guide plate is inclined downward on the outer surface of the power distribution cabinet body corresponding to the top position of the exhaust port, and water baffles are provided between the two ends of the water guide plate and the power distribution cabinet body.

[0013] Furthermore, the temperature sensor, the ventilation fan, the blower, and the drive motor in the linear transmission mechanism are all electrically connected to the control module.

[0014] Compared with existing technologies, the advantages of this utility model are as follows: This utility model has a reasonable design, simple and stable structure, and strong practicality; it innovatively adopts a convection ventilation structure with horizontal side air intake and vertical single-side air exhaust. Through the layout design of the ventilation fan and exhaust port, a three-dimensional air circulation path is constructed through the installation area of ​​electronic components, which greatly improves the contact efficiency between airflow and heat-generating elements and accelerates heat dissipation; the temperature sensor integrated in the support mounting plate can accurately monitor the temperature of each area in real time.

The control module 9 is provided. A fan 10 is installed on the top of the support base plate 1 on one side of the distribution cabinet body 2. A lifting support mounting plate 11 is provided between the support mounting plate 5 and the ventilation fan 8. The two ends of the lifting support mounting plate 11 are slidably connected to the inner surfaces of the two sides of the distribution cabinet body 2 in the vertical direction. A wind box 12 is provided on the side of the lifting support mounting plate 11 closest to the support mounting plate 5.

An air distribution plate is provided inside the wind box 12. A semiconductor cooling chip is provided on the side of the air distribution plate away from the air outlets 13.

[0024] A moisture-proof base is provided at the bottom of the support base plate 1.

The moisture-proof board is made of anti-corrosion and waterproof material, which can effectively isolate ground moisture and water accumulation from the corrosion of the distribution cabinet body 2, so as to protect the electronic components inside the cabinet from moisture damage. An arc-shaped protective guide plate 14 is provided on the top of the distribution cabinet body 2 to guide rainwater, leaves, snow and other debris, so as to prevent the accumulation of foreign objects on the top of the distribution cabinet body 2. The outer surface of the distribution cabinet body 2 is corresponding to the row of... A water guide plate 15 is inclined downward at the top of the air vent 7. Water baffles are installed between the two ends of the water guide plate 15 and the main body 2 of the distribution cabinet. The inclined water guide plate 15, together with the water baffles at both ends, forms a "rainproof eaves" structure, which can effectively prevent rainwater from flowing back into the main body 2 of the distribution cabinet from the air vent 7, while not affecting the airflow of the exhaust duct. The fan 10 is a centrifugal variable frequency fan, used to control different operating frequencies of the fan 10 based on the data monitored by the temperature sensor 6. The lifting support mounting plate 11 has two ends respectively... The cabinet has a slider, and the inner wall of the distribution cabinet body 2 is vertically equipped with guide rails. The lifting support mounting plate 11 is slidably connected to the inner surfaces of the two sides of the distribution cabinet body 2 through the structure of the slider and the guide rails, so that the lifting support mounting plate 11 can be lifted and lowered smoothly. A linear transmission mechanism 16 is set between the bottom of one end of the lifting support mounting plate 11 and the inner surface of the side of the distribution cabinet body 2. The linear transmission mechanism 16 is a transmission structure in which the drive motor is equipped with a transmission gear and a transmission rack to realize the automatic lifting and lowering of the lifting support mounting plate 11. The hot end of the semiconductor cooling chip is set on the outside of the distribution cabinet body 2, and the cold end of the semiconductor cooling chip is set inside the air box 12, which avoids the heat of the hot end of the semiconductor cooling chip from accumulating in the cabinet and improves the cooling efficiency. The temperature sensor 6, the ventilation fan 8, the fan 10 and the drive motor in the linear transmission mechanism 16 are all electrically connected to the control module 9, so as to receive the data transmitted by the temperature sensor 6 and control the working status of the drive motor in the ventilation fan 8, the fan 10 and the linear transmission mechanism 16.

[0025] Working principle:

[0026] When the electronic components inside the power distribution cabinet are working normally, the ventilation fan actively draws air into the cabinet and exhausts it through the exhaust vent, forming a three-dimensional convection path that runs through the support mounting plate area. This replaces the air inside the power distribution cabinet and also removes the heat generated by the electronic components during normal operation. Temperature sensors on each support mounting plate monitor the temperature of the corresponding area in real time and transmit the data to the control module.

[0027] When the control module determines that the temperature in a certain area is abnormal (such as exceeding the preset threshold), it immediately activates the linear transmission mechanism (the drive motor engages with a gear and rack) to drive the lifting support mounting plate to slide vertically along the guide rail, accurately positioning the air box to the high-temperature area. At this time, the centrifugal variable frequency fan adjusts its speed according to the temperature data, pressurizing the external air into the air box. After being cooled by the cold end of the internal semiconductor cooling chip and the air distribution plate evens the airflow, the air is directionally blown through the air outlet to the heating element to achieve targeted cooling.
