Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, specifically to outdoor photovoltaic energy storage electrical equipment. Background Technology

[0002] The power system is a unified whole consisting of power generation, power supply (transmission, transformation, and distribution), power consumption facilities, and secondary facilities such as regulation and control, relay protection and safety automatic devices, metering devices, dispatch automation, and power communication required to ensure its normal operation. Power consumption equipment is one of the components of the power system.

[0003] Currently, electrical equipment enclosures are typically equipped with ventilation openings to allow for air circulation and heat dissipation. While this achieves air circulation and heat dissipation, the ventilation openings, which are close to the ground, are prone to water, dust, and insects entering the enclosure, causing damage to the electrical equipment inside. Furthermore, the air entering the enclosure through the ventilation openings cannot circulate throughout the entire space, resulting in incomplete heat dissipation. Utility Model Content

[0010] Preferably, the bottom of the electrical box is provided with a base, and the base on opposite sides of the electrical box is provided with mounting holes.

[0011] Preferably, the top and bottom of the inner side of the flow port are provided with air guide plates, and the air guide plates are arranged in a trumpet shape.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This outdoor photovoltaic energy storage device achieves air circulation and heat dissipation inside and outside the power box through the air intake and exhaust mechanisms installed on the power box. The air intake box is located at the upper end of one side of the power box, and the air exhaust box is located at the top of the power box.

[0023] like Figures 1 to 4 As shown, the outdoor photovoltaic energy storage device in this embodiment includes an electrical box 1. A door 11 is hinged on one side of the electrical box 1. An air inlet mechanism is connected to the upper part of the electrical box 1 on the side away from the door 11. A heat-conducting plate 4 is provided inside the electrical box 1 on the side away from the door 11. A ventilation channel 41 is formed between the side of the electrical box 1 near the air inlet mechanism and the heat-conducting plate 4. A flow outlet 42 is provided at the lower end of the heat-conducting plate 4. An air outlet mechanism is connected to the top of the electrical box 1. A shielding plate 5 is provided on the top of the electrical box 1 via a support frame 6. A solar panel 7 is fixed to the top of the shielding plate 5 with bolts, enabling air circulation and heat dissipation inside and outside the electrical box 1. The heat dissipation airflow flows from bottom to top throughout the entire interior of the electrical box 1, resulting in a wide and comprehensive heat dissipation area. The air inlet and outlet of the electrical box 1 are far from the ground, and the shielding plate 5 protects the air inlet and outlet, preventing damage caused by water, dust, or insects entering the outdoor electrical equipment.

[0024] Specifically, the air intake mechanism includes an air intake box 2, an air intake filter 21, and a dehumidifying plate 22. The air intake box 2 is connected to the upper end of the electrical box 1 on the side of the heat conduction plate 4 away from the box door 11. The air intake box 2 is equipped with an air intake filter 21 on the side of the air intake box 2 away from the electrical box 1. The air intake filter 21 is equipped with a dehumidifying plate 22 on the side of the air intake box 2 close to the electrical box 1. The air intake filter 21 and the dehumidifying plate 22 are both fixedly installed inside the air intake box 2 by bolts. The low-temperature air from outside enters the air flow channel 41 between the heat conduction plate 4 and the electrical box 1 after being dusted by the air intake filter 21 and dehumidified by the dehumidifying plate 22.

[0025] Furthermore, the air outlet mechanism includes an air outlet box 3, a fan 31, and an air outlet 32. The air outlet box 3 is connected to the middle of the top of the electrical box 1. The fan 31 is installed inside the air outlet box 3. The air outlet 32 ​​is provided on the side of the air outlet box 3 near the box door 11. The air outlet box 3 is located at the bottom of the baffle plate 5. Under the action of the fan 31 inside the air outlet box 3, the high temperature air inside the electrical box 1 is discharged through the air outlet 32 ​​on the air outlet box 3, and the low temperature air outside enters the electrical box 1 through the air inlet box 2 and the air inlet mechanism.

[0026] Furthermore, the inner wall of the air outlet box 3 is provided with sound insulation cotton 33, and the air outlet 32 ​​is provided with an air filter. The sound insulation cotton 33 is used to insulate the fan 31 running inside the air outlet box 3, and the air filter is used to protect the air outlet 32 ​​from dust.

[0027] Furthermore, the shield 5 is arranged in a V-shape. The lower end of one side of the shield 5 is inclined downward and extends to the outer side above the door 11, while the lower end of the other side of the shield 5 is inclined downward and extends to the outer side above the air inlet box 2, which can shield and protect the air outlet box 3, the air inlet box 2, and the door 11.

[0028] Furthermore, the bottom of the electrical box 1 is provided with a base 12, and mounting holes are provided on the base 12 on opposite sides of the electrical box 1, making the electrical box 1 easy to install.

[0029] Furthermore, air guide plates 43 are provided at the top and bottom of the inner side of the flow port 42. The air guide plates 43 are arranged in a trumpet shape. The air guide plates 43 guide the airflow flowing through the flow port 42. The guided airflow flows more concentratedly into the lower end of the electrical box 1. The airflow has a larger area of ​​flow in the lower end of the electrical box 1, and then the airflow rises and dissipates heat from the lower end of the electrical box 1.

[0030] The usage method of this embodiment is as follows: By fixing the base 12, the electrical box 1 is fixedly installed outdoors. Under the action of the fan 31 in the air outlet box 3, the high-temperature air inside the electrical box 1 is discharged from the air outlet 32 ​​on the air outlet box 3. The low-temperature air outside enters the air flow channel 41 between the heat conduction plate 4 and the electrical box 1 after passing through the air inlet filter 21 for dust removal and the dehumidification plate 22 for dehumidification in the air inlet box 2. The low-temperature heat dissipation airflow flows from top to bottom in the air flow channel 41, and enters the interior of the electrical box 1 through the flow port 42 at the bottom of the heat conduction plate 4 and the air guide plate 43. That is, the low-temperature heat dissipation airflow entering from the high position is guided by the air flow channel 41 and then enters the interior of the electrical box 1 from the low position. The airflow inside the electrical box 1 flows from bottom to top, achieving air circulation and heat dissipation between the inside and outside of the electrical box 1. The heat dissipation airflow flows from bottom to top throughout the entire interior of the electrical box 1, with a wide heat dissipation circulation area and comprehensive heat dissipation. The air inlet box 2 is located at the upper end of one side of the electrical box 1, and the air outlet box 3 is located at the top of the electrical box 1. Combined with the baffle plate 5 set on the top of the electrical box 1 by the support frame 6, the lower end of one side of the baffle plate 5 is inclined downward and extends to the outer side above the box door 11, and the lower end of the other side of the baffle plate 5 is inclined downward and extends to the outer side above the air inlet box 2. The air inlet and air outlet 32 ​​on the electrical box 1 are far away from the ground. The baffle plate 5 blocks and protects the air inlet and air outlet 32 ​​to prevent damage caused by water, dust, and insects entering the electrical equipment outdoors.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
