[0005] Furthermore, the surface of the air guide cover is provided with a sound insulation layer.

[0006] Furthermore, the heat dissipation chamber is equipped with a PCS, UPS, and photovoltaic controller.

[0007] Furthermore, the angle between the air outlet's airflow direction and the air guide shroud's airflow direction is a right angle.

[0008] Furthermore, the cross-sectional shape of the air guide shroud is trapezoidal or semi-circular.

[0009] Furthermore, the side of the air guide shroud closest to the air inlet is provided with a partition along the vertical direction.

The side wall of the cabinet body 1 is provided with a cabinet door 11. The cabinet door 11 is provided with an air inlet 111 at the position corresponding to the closed chamber 4. The inner side of the air inlet 111 is covered with an air guide 12. When the cabinet door 11 is closed, the air guide 12 squeezes the sealing strip 21. The side wall of the heat dissipation chamber 3 away from the cabinet door 11 is provided with an air outlet 31. The angle between the air outlet 31 and the air guide 12 is an acute angle or a right angle.

[0024] As can be seen from the above description, the beneficial effects of this utility model are as follows: a low-noise energy storage cabinet, the heat dissipation chamber 3 is used to place electrical components, so only the heat dissipation noise of the heat dissipation chamber 3 needs to be considered. When the cabinet door 11 is closed, the sealing strip 21 is squeezed and deformed, completely separating the heat dissipation chamber 3 and the closed chamber 4. Due to the staggered design of the air inlet 111 and the air outlet 31, and the use of the air guide shroud 12 to change the air flow direction, on the one hand, the noise of the electrical components is prevented from being directly emitted outside the cabinet. The noise is deflected and emitted after being deflected by the air guide shroud 12, thus reducing the noise. On the other hand, it can also achieve rapid and effective heat dissipation.

[0025] In an optional embodiment, the surface of the air guide shroud 12 is provided with a sound insulation layer 121.

[0026] As can be seen from the above description, the sound insulation layer 121 plays a role in sound insulation and noise reduction.

[0027] In an optional embodiment, the heat dissipation chamber 3 is equipped with PCS32, UPS33 and photovoltaic controller 34.

[0028] In an optional embodiment, the angle between the air outlet 31's air outlet direction and the air guide shroud 12's air guide direction is a right angle.

[0029] As can be seen from the above description, the shape of the air guide shroud 12 causes the noise to bend 90° and then bend 90° again before being dissipated, thereby reducing noise.

[0030] In an optional embodiment, the cross-sectional shape of the air guide shroud 12 is trapezoidal or semi-circular.

[0031] As can be seen from the above description, the shape of the sealing strip 21 is adapted to the cross-sectional shape of the air guide shroud 12, and the two do not affect the opening and closing of the door when they come into contact.

[0032] In an optional embodiment, the side of the air guide shroud 12 near the air inlet 111 is provided with a partition 122 in the vertical direction.

[0033] As can be seen from the above description, the partition 122 separates the inner cavity of the air guide shroud 12, reducing the noise generated by the airflow and achieving a further noise reduction effect.

[0034] In an optional embodiment, the space between the air guide shroud 12 and the inner wall of the cabinet door 11 is divided into two or more air ducts 123 with the same cross-sectional area by a partition 122.

[0035] As can be seen from the above description, since the cross-sectional areas of the two air ducts 123 are equal, the airflow distribution is more uniform, and the consistency in pressure can further improve the noise reduction effect.

[0036] In an optional embodiment, two or more partitions 122 are arranged horizontally at intervals on the side of the air guide shroud 12 near the air inlet 111.

[0037] In an alternative embodiment, the surface of the partition 122 is provided with sound-absorbing cotton 124.

[0038] As can be seen from the above description, the silencing cotton 124 is designed to better reduce noise levels.

[0039] In an alternative embodiment, the partition 122 is wavy in shape.

[0040] As can be seen from the above description, the wave-shaped partition 122 is used to lengthen the propagation path in the morning through refraction, thereby reducing the noise level.

[0041] Please refer to Figures 1 to 5. Embodiment 1 of this utility model is as follows: A low-noise energy storage cabinet includes a cabinet body 1. The interior of the cabinet body 1 is divided into a heat dissipation chamber 3 and a closed chamber 4 by a shelf 2. The edge of the shelf 2 is provided with a sealing strip 21. The side wall of the cabinet body 1 is provided with a cabinet door 11. The cabinet door 11 is provided with an air inlet 111 at the position corresponding to the closed chamber 4. The inner side of the air inlet 111 is covered with a guide hood 12. When the cabinet door 11 is closed, the guide hood 12 squeezes the sealing strip 21. The interference between the sealing strip 21 and the cabinet door 11 is 7mm. The side wall of the heat dissipation chamber 3 away from the cabinet door 11 is provided with an air outlet 31. The angle between the air outlet 31 and the air guide hood 12 is an acute angle or a right angle.

[0042] The surface of the air guide shroud 12 is provided with a sound insulation layer 121. The heat dissipation chamber 3 houses a PCS 32, a UPS 33, and a photovoltaic controller 34. The angle between the air outlet 31's airflow direction and the air guide shroud 12's airflow direction is a right angle. The cross-sectional shape of the air guide shroud 12 is trapezoidal or semi-circular. A partition 122 is provided vertically on the side of the air guide shroud 12 near the air inlet 111. The space between the air guide shroud 12 and the inner wall of the cabinet door 11 is divided into two or more air ducts 123 with the same cross-sectional area by the partition 122. Two or more partitions 122 are spaced horizontally on the side of the air guide shroud 12 near the air inlet 111. The surface of the partition 122 is provided with sound-absorbing cotton 124. The partition 122 has a wavy shape.

[0043] In summary, the low-noise energy storage cabinet of this utility model has a heat dissipation chamber for housing electrical components. This way, only the heat dissipation noise of the heat dissipation chamber needs to be considered. When the cabinet door is closed, the sealing strip is squeezed and deformed, completely separating the heat dissipation chamber and the enclosed chamber. Due to the staggered design of the air inlet and outlet, and the use of the air guide hood to change the airflow direction, on the one hand, the noise of the electrical components is prevented from being directly emitted outside the cabinet. The noise is deflected by the air guide hood before being emitted, thus reducing the noise. On the other hand, it can also achieve rapid and effective heat dissipation.
