Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and in particular to an integrated energy storage device. Background Technology

[0002] As photovoltaic power generation systems occupy an increasingly larger share of energy supply, the randomness, intermittency, and volatility of independent photovoltaic power generation will inevitably affect the safe and stable operation of the system. In order to ensure the safety, stability, and power quality of microgrid systems that include photovoltaics, it is necessary to equip photovoltaic power generation with a certain amount of energy storage. Therefore, most systems are equipped with an energy storage device for simultaneous use.

[0003] However, existing energy storage devices generally only have a few ventilation holes on the bottom box for heat dissipation. Once used for a long time, due to their complex internal structure, heat can easily accumulate, which is not conducive to heat dissipation and will affect their service life to some extent, which is quite troublesome.

[0034] By setting a straight-through air duct 5 in the bottom box 1, and cooperating with an air inlet 6 and an air outlet 7, when dissipating heat, the airflow enters the straight-through air duct 5 from the air inlet 6 and flows out of the air outlet 7, which can form a straight airflow in the control motherboard module 2 with fewer bends, a shorter airflow path, high heat dissipation efficiency, and reduced noise, making it practical and convenient.

[0035] In this embodiment, the energy storage battery module 2, the control motherboard module 3, and the inverter module 4 are all conventional structures in the prior art, and are simply applied, so they are not described in detail.

[0036] In this embodiment, the energy storage battery module 2 can also be configured with a BMS battery management system to achieve rapid disconnection of various faults. The BMS battery management system is a conventional system in the prior art and is simply applied, so it is not described in detail.

[0037] Furthermore, the air inlet 6 includes an air inlet cavity 61 opened on the side wall of the bottom box 1, and a plurality of air inlet holes 62 through the bottom wall of the air inlet cavity 61.

[0038] Furthermore, a dustproof net 8 is also installed on the air inlet cavity 61.

[0039] Specifically, a plurality of slots 610 are provided on one side wall of the air inlet cavity 61, and a plugging protrusion 80 is provided on one side of the dustproof net 8, which can be inserted into the slot 610 accordingly. A connecting post 611 is also provided in the air inlet cavity 61. One end of the dustproof net 8 is inserted into the slot 610 through the plugging protrusion 80, and the other end is connected to the connecting post 611 by a screw.

[0040] During installation, fill the air inlet cavity 61 with dustproof cotton, then insert the plug protrusion 80 on the dustproof mesh 8 into the slot 610, then flip it over and press it down to embed it into the air inlet cavity 61 and press the dustproof cotton tightly, and finally connect it to the connecting post 611 with screws.

[0041] By using dustproof net 8 and dustproof cotton, external sand and dust are prevented from entering the bottom box 1 through air inlet 6, protecting the control motherboard module 3. It can achieve heat dissipation through airflow while keeping sand and dust out, which is practical and convenient.

[0042] Furthermore, several cooling fans 70 are installed inside the straight-through air duct 5 near the air outlet 7.

[0043] By setting up several cooling fans 70, airflow is accelerated, and a directional airflow direction of air inlet 6 → straight-through air duct 5 → air outlet 7 can be formed in the bottom box 1, which is practical and convenient and greatly improves heat dissipation performance.

[0044] Furthermore, a display screen 9 is also embedded in the cover plate 10. The display screen 9 is electrically connected to the control motherboard module 3.

[0050] Furthermore, the inverter module 4 includes a mounting bracket 41 connected to the base box 1 and an inverter 42 mounted on the mounting bracket 41.

[0051] In this embodiment, the inverter 42 is a conventional structure in the prior art, and is simply applied, so it is not described in detail.

[0052] Furthermore, a wall-mounting assembly 105 is also provided on the rear wall of the base box 1. Through the design of the wall-mounting assembly 105, the base box 1 can be hung on the wall, saving space, optimizing the layout of the usage scenario, and improving space utilization.

[0053] In summary, the embodiments of this application, by setting a straight-through air duct 5 in the bottom box 1 and cooperating with the air inlet 6 and air outlet 7, allow airflow to enter the straight-through air duct 5 from the air inlet 6 and flow out of the air outlet 7 during heat dissipation. This can form a straight airflow in the control motherboard module 2, with fewer bends, a shorter airflow path, high heat dissipation efficiency, and reduced noise, making it practical and convenient.

[0054] Meanwhile, the dustproof net 8 and dustproof cotton prevent external sand and dust from entering the bottom box 1 through the air inlet 6, protecting the control motherboard module 3. It can achieve heat dissipation through airflow while keeping sand and dust out, which is practical and convenient.

[0055] Furthermore, the design of the wall-mounted component 105 allows the base box 1 to be mounted on the wall, saving space, optimizing the layout of usage scenarios, and improving space utilization.
