Description

Technical Field

[0001] The utility model relates to an AC / DC integrated outdoor energy storage cabinet, in particular to a waterproof and dustproof AC / DC outdoor energy storage cabinet. Background Art

[0002] In the prior art, common outdoor AC / DC energy storage cabinets have an IPX6 protection rating for their battery compartment, liquid cooling unit, and high-voltage box, while the electrical compartment has an IP20 protection rating. The ventilation mesh holes in the electrical compartment are suitable for ventilation and heat dissipation of the liquid cooling unit. Currently, mainstream outdoor energy storage cabinets are typically integrated AC / DC outdoor cabinets, with the liquid cooling unit and PCS (converter) housed in the same electrical compartment. However, the PCS itself has an IP20 protection rating, which requires the electrical compartment to have an IPX4 or IPX5 protection rating. This means that the electrical compartment must be ventilated, dustproof, and waterproof, while also being quiet. Conventional louvered structures cannot meet these protection requirements. Utility Model Content

[0020] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0021] The utility model discloses a waterproof and dustproof AC and DC outdoor energy storage cabinet, combined with Figures 1 to 6 As shown, it includes a cabinet body 1, and a ventilation window assembly is provided on the cabinet body 1, and the ventilation window assembly includes a mesh plate 2, a first louver 3, a second louver 4 and a water receiving trough 5 arranged in sequence from the outside to the inside, the first louver 3 includes a plurality of first inverted Z-shaped louvers 30, and the plurality of first inverted Z-shaped louvers 30 are arranged at equal intervals from top to bottom, and the outer side slope of the first inverted Z-shaped louvers 30 faces obliquely upward, the second louver 4 includes a plurality of second inverted Z-shaped louvers 40, and the plurality of second inverted Z-shaped louvers 40 are arranged at equal intervals from top to bottom, and the outer side slope of the second inverted Z-shaped louvers 40 faces obliquely upward, the water receiving trough 5 is arranged below the first louvers 3 and the second louvers 4, and the water receiving trough 5 is evenly distributed with a plurality of drainage holes 50.

[0022] In the above structure, the ventilation window assembly provided on the cabinet body 1 can realize ventilation between the cabinet and the outside space. The mesh plate 2 is located on the outermost side to prevent flying insects and foreign objects from entering the cabinet. The first louvers 3 are located on the second layer, wherein the plurality of first inverted Z-shaped louvers 30 are arranged at equal intervals from top to bottom. Figure 5 and Figure 6 Because the outer side slope of the first inverted Z-shaped louver 30 faces obliquely upward, it plays a better role in water blocking and waterproofing. On this basis, the second louver 4 is used as the third layer structure of the ventilation window assembly, and multiple second inverted Z-shaped louvers 40 are arranged at equal intervals from top to bottom. Under the joint action of the mesh plate 2, the first louver 3 and the second louver 4, the ventilation window assembly not only achieves ventilation, but also has a higher insect and foreign body prevention and waterproof and dustproof effect, so the protection performance is better, thereby meeting the application requirements.

[0023] In addition, this embodiment provides the water receiving trough 5 and multiple drainage holes 50 below the first louver 3 and the second louver 4, so that the dripping water blocked by the first inverted Z-shaped louver 30 and the second inverted Z-shaped louver 40 can be discharged in time, thereby ensuring that the ventilation window assembly is in a dry state without residual water.

[0024] See Figure 3 、 Figure 5 and Figure 6 In this embodiment, the first inverted Z-shaped louvers 30 and the second inverted Z-shaped louvers 40 are aligned one-to-one. The first inverted Z-shaped louvers 30 and the second inverted Z-shaped louvers 40 in the first louver 3 and the second louver 4 are aligned front to back, and have the same shape and size. The combined effect of the first inverted Z-shaped louvers 30 and the second inverted Z-shaped louvers 40 effectively prevents splashing inside the water tank cabinet.

[0025] For the preferred structure of reverse Z-shaped louvers, please refer to Figure 4 In this embodiment, the first inverted Z-shaped louver 30 includes an inclined portion 300, and an upper vertical portion 301 and a lower vertical portion 302 disposed at the upper and lower ends of the inclined portion 300. Furthermore, a forward-bent portion 303 is formed at the upper end of the upper vertical portion 301. The angle between the bent portion 303 and the upper vertical portion 301 is 60°.

[0026] In the above structure, this embodiment preferably provides a forward-bending bent portion 303 at the upper end of the upper vertical portion 301. Specifically, the bent portion 303 is bent at a 60° angle relative to the upper vertical portion 301, tilting slightly downward. This bend 303 prevents water from splashing over the upper vertical portion 301 and into the cabinet, further enhancing the water-blocking and waterproofing effects. Furthermore, the second inverted Z-shaped louver 40 has the same shape as the first inverted Z-shaped louver 30. Based on this structural arrangement, the cabinet's waterproof rating meets IPX4 requirements.

[0027] In order to achieve in-and-out ventilation, in this embodiment, the cabinet body 1 includes an air inlet 10 and an air outlet 11, and the air inlet 10 and the air outlet 11 are both provided on the ventilation window assembly.

[0028] As a preferred method, see Figure 5 and Figure 6 The air inlet 10 is installed with the ventilation window assembly including polyurethane filter cotton 6, and the polyurethane filter cotton 6 is arranged on the side of the second venetian blind 4 facing away from the first venetian blind 3.

[0029] In actual application, filter cotton needs to be set for the air inlet 10, that is, the innermost polyurethane filter cotton 6 is used to further prevent dust. Since the air flow enters the cabinet through the air inlet 10, it is only necessary to set filter cotton at the air inlet 10, and there is no need to set filter cotton on the side of the air outlet 11.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the technical scope of the present invention should be included in the scope of protection of the present invention.
