Description
Technical Field
[0001] The utility model relates to the technical field of power distribution cabinets, in particular to an outdoor power distribution cabinet with good heat dissipation performance. Background Art
[0002] The JP cabinet is abbreviated as the power distribution cabinet, which is a general term for the motor control center. During the use of new energy power generation equipment, outdoor power distribution cabinets are required. Power distribution cabinets are used in places where the load is relatively dispersed and there are fewer circuits; motor control centers are used in places where the load is concentrated and there are more circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load.
[0003] At present, an outdoor air-cooled low-voltage power distribution cabinet, as described in the patent publication number CN212210248U, comprises: a cabinet body, a cabinet door movably connected to the front of the cabinet body, a door lock movably installed inside the cabinet door, a cabinet top fixedly connected to the top of the cabinet body, and a moisture-proof groove on one side of the front of the cabinet body.
[0004] With respect to the above-mentioned related technologies, the applicant believes that when an outdoor air-cooled low-voltage power distribution cabinet is working, air is attracted to the bottom from the air inlets on the inner walls on both sides through the cooling fan at the bottom of the main body, and the cooling fan blows air vertically to the upper structure for heat dissipation. This will cause the airflow coming in from the air inlet to collide with the rising airflow, making the internal air circulation more chaotic, resulting in low cooling efficiency of the cooling fan. Utility Model Content
[0005] The purpose of the utility model is to provide an outdoor power distribution cabinet with good heat dissipation performance to solve the problems raised in the above background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an outdoor power distribution cabinet with good heat dissipation, comprising a power distribution cabinet, an air inlet is opened on the outer wall of the power distribution cabinet, a heat dissipation fin is fixedly installed on the inner wall of the power distribution cabinet, a partition is fixedly installed on one side of the heat dissipation fin, a fan is fixedly installed on the outer wall of the power distribution cabinet, a dust cover is fixedly installed on the outer wall of the power distribution cabinet on the fan side, a ceiling is fixedly installed on the top of the power distribution cabinet, a solar panel is fixedly installed on the top of the ceiling, a battery is fixedly installed inside the ceiling, a controller is fixedly installed inside the ceiling, and a temperature sensor is fixedly installed on one side of the partition.
[0007] By adopting the above technical solution, most of the heat generated in the distribution cabinet is absorbed by the heat dissipation fins, and the temperature sensor transmits the internal temperature signal to the controller. The fan rotation is controlled to discharge the internal air outward, and negative pressure is generated inside to cause the air inlet to inhale air. The inhaled air can only flow through the gaps in the heat dissipation fins to one side of the partition and be discharged by the fan. The heat absorbed by the heat dissipation fins is transferred to the flowing airflow for discharge, thereby achieving the effect of efficient cooling.
[0008] Preferably, a smoke sensor is fixedly installed on the inner top of the power distribution cabinet, a spark sensor is fixedly installed on the inner top of the power distribution cabinet, and a wireless transmitter is fixedly installed inside the ceiling.
[0009] By adopting the above technical solution, internal electrical appliances can be monitored through smoke sensors and spark sensors. When a short circuit occurs and smoke and sparks are generated, the monitored signal will be sent to the computer by the wireless transmitter, so that the distribution station personnel can disconnect the power supply in time and send people to check, avoiding fire that causes economic losses and casualties.
[0010] Preferably, a fixing strip is fixedly mounted on the front side of the heat dissipation fin, and a dustproof net is fixedly mounted on the inner side of the air inlet.
[0011] By adopting the above technical solution, by installing fixing strips on the heat dissipation fins, the power distribution connection components can be fixed on the fixing strips. The heat emitted during operation can be quickly absorbed by the heat dissipation fins. When the air flows, more heat is taken away and the cooling is more obvious. At the same time, a dust net is installed to prevent the inhalation of outdoor dust and impurities from affecting internal components.
[0012] Preferably, the smoke sensor and the spark sensor are electrically connected to the controller, the controller is electrically connected to the wireless transmitter, the solar panel and the battery, and the antenna of the wireless transmitter is placed on the top of the ceiling.
[0013] By adopting the above technical solution, the monitoring signal is transmitted to the controller through the smoke sensor and the spark sensor, and the controller controls the wireless transmitter to transmit the signal to the computer, so that the distribution station can monitor the internal status in real time. At the same time, the solar panel generates electricity to charge the battery, which can provide power for the device without reconnecting the wires.
[0014] Preferably, the temperature sensor is electrically connected to the controller, and the controller is electrically connected to the fan.
[0015] By adopting the above technical solution, the temperature inside the distribution cabinet can be monitored by a temperature sensor, and the signal can be transmitted to the controller to control the fan to dissipate heat, thereby achieving intelligent control of heat dissipation and saving electricity.
[0016] Preferably, the fins of the heat dissipation fin plate are arranged horizontally, and one side of the gap of the heat dissipation fin plate is communicated with the partition plate.
[0017] By adopting the above technical solution, the heat dissipation fins passing through the transverse fins are the same as the partitions, and the inhaled air can only flow through the transverse fin gaps, so that the air can fully contact and take away the heat on the heat dissipation fins, thereby achieving the effect of efficient cooling.
[0018] Preferably, the partition is spaced apart from the inner wall of the power distribution cabinet and together with the fan forms an air intake structure.
[0019] By adopting the above technical solution, the air in the space separated by the partition can be discharged through the fan to generate negative pressure in the space, and the air can only be sucked in through the connection between the partition and the heat dissipation fins, so that there is only one air flow route, avoiding the problem of poor heat dissipation effect caused by collision of air flows in the prior art.
[0020] Compared with the prior art, the beneficial effects of the utility model are:
[0021] (1) The temperature sensor transmits the internal temperature signal to the controller, controls the fan to start and discharge the air outward, and generates negative pressure inside to cause the air inlet to inhale air. The inhaled air can only flow through the gap between the heat dissipation fins to the side of the partition and be discharged by the fan. The air flowing through the heat dissipation fins will absorb the heat on the fins, achieving the effect of internal air flow to remove heat and cool down. The internal heat dissipation air flow line is fixed and the air flow disorder will not occur, thereby improving the heat dissipation capacity of the distribution box;
[0022] (2) The internal electrical appliances are monitored through smoke sensors and spark sensors. If a short circuit occurs, smoke and sparks will be generated. The monitored signal can be transmitted to the controller, which controls the wireless transmitter to send it to the computer end, so that the distribution station personnel can disconnect the power supply of the line in time and send someone to check it out, avoiding fire that causes economic losses and casualties.

A temperature sensor 12 is fixedly installed on one side of the partition 5. The model of the temperature sensor 12 may be RTT511M-A-4-6-050, which can monitor the internal temperature and transmit it to the controller 11 to control the heat dissipation of the fan 6.
[0032] See also Figures 1 to 3 A smoke sensor 14 is fixedly installed on the top of the power distribution cabinet 1. The model of the smoke sensor 14 may be RS485, which is used to monitor whether smoke is generated inside. A spark sensor 15 is fixedly installed on the top of the power distribution cabinet 1.

When a short circuit occurs to generate smoke and sparks, the monitored signal will be sent to the computer by the wireless transmitter 13, so that the power distribution station personnel can disconnect the power supply in time and send people to check, so as to avoid fire causing economic losses and deaths.
[0033] A fixing strip 16 is fixedly installed on the front of the heat dissipation fin 4, and the power distribution connection components are fixed on the fixing strip 16. The heat emitted during operation can be quickly absorbed by the heat dissipation fin 4. When the air flows, more heat is taken away and the cooling is more obvious. A dustproof net 3 is fixedly installed on the inner side of the air inlet 2. The dustproof net 3 is installed to prevent the inhalation of outdoor dust and impurities from affecting the internal components. The smoke sensor 14 and the spark sensor 15 are electrically connected to the controller 11, and the controller 11 is electrically connected to the wireless transmitter 13, the solar power generation panel 9 and the battery 10.

[0034] See also Figures 3 to 5 The temperature sensor 12 is electrically connected to the controller 11, and the controller 11 is electrically connected to the fan 6.

The heat dissipation fin 4 of the horizontal fin is the same as the partition 5.

[0035] Working principle: When in use, the solar panel 9 first generates electricity and charges the battery 10 for daily use of the heat dissipation device. When the temperature sensor 12 detects that the internal temperature is too high, it transmits a signal to the controller 11 to control the operation of the fan 6;
[0036] Secondly, when the fan 6 is working, it will exhaust the internal air to generate negative pressure, and inhale air through the air inlet 2. The air flows through the gaps of the heat dissipation fins 4 and absorbs the heat on the fins, reducing the internal heat to achieve cooling;
[0037] Finally, the flowing air will enter the compartment on one side of the partition 5 and be discharged by the fan 6, thereby achieving the effect of internal air flow exchange and cooling.
