The safety and stability of the energy storage batteries during operation are guaranteed by the coordinated use of various control and monitoring components in the battery plug-in box. During use, the battery plug-in box needs to be inserted into the battery plug-in box socket set on the corresponding electrical cabinet. The battery box generates a lot of heat during early charging and discharging, which needs to be dissipated outward in a timely manner.

The cooling system is installed within the box body and includes an air inlet and a deflector. The air inlet is used to introduce cold air and is located on the side wall at the rear of the box body. The air inlet includes several transverse air inlets near the bottom of the box body and several longitudinal air inlets away from the bottom of the box body. The deflector is arranged parallel to the bottom surface of the box body and divides the space within the box body into upper and lower flow channels.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-5 The utility model provides a technical solution: an electrical cabinet for circulating cooling of an energy storage battery plug-in box, comprising an electrical cabinet body 1, an electrical cabinet door 2, a heat dissipation slot 3, a blowing device 4, a cooling pipe 5, a cooling device 6, a limiting mechanism 7, a dustproof net 8, a mounting plate 9, a side plate 10, a mounting slot 11, a fixing column 12, a support block 13, an auxiliary rod 14, a fixing plate 15 and a fixing slot 16.

[0029] When using this energy storage battery box to cool the electrical cabinet, Figure 1 、 Figure 2 and Figure 5 As shown, an electrical cabinet door 2 is installed on the front side of the electrical cabinet body 1, and heat dissipation slots 3 are opened on the left and right sides of the electrical cabinet body 1, and a blowing device 4 is fixedly installed on both sides of the electrical cabinet body 1. At the same time, the blowing device 4, cooling pipe 5 and dustproof net 8 are staggered on the left and right sides of the electrical cabinet body 1. When the battery box is in the charging and discharging state, a large amount of heat is generated. At this time, the blowing device 4 and the cooling device 6 are started, and the interior of the electrical cabinet body 1 is blown by the blowing device 4. At the same time, the cooling pipe 5 is connected to the cooling device 6, and the cooling device 6 circulates and cools the coolant inside the cooling pipe 5. The air blown out of the blowing device 4 is circulated and cooled through the cooling pipe 5, thereby accelerating the heat inside the electrical cabinet body 1 to be dissipated outward through the electrical cabinet door 2, thereby achieving a better heat dissipation effect. Moreover, the cooling pipe 5 is curved in the electrical cabinet body 1, thereby increasing the contact area with the air blown out by the blowing device 4, thereby improving the actual cooling efficiency;

[0030] Moreover, in the actual heat dissipation process, the dustproof net 8 is set, the dustproof net 8 is fixedly connected to the middle of the mounting plate 9, and the dustproof net 8 is respectively arranged on both sides of the electrical cabinet body 1, thereby preventing the external dust from being brought into the electrical cabinet body 1 during the ventilation and heat dissipation process and adhering to the equipment inside the electrical cabinet body 1 to cause dust accumulation, and the dustproof effect is good. Moreover, when there is too much dust on the dustproof net 8, such as Figure 1 、 Figure 3 and Figure 4As shown, the limiting mechanism 7 includes a fixing column 12 fixedly connected to the outer side of the upper end of the mounting plate 9, a support block 13 fixedly connected to the side of the side plate 10, an auxiliary rod 14 hingedly connected to the middle of the support block 13, a fixing plate 15 for connection, and a fixing slot 16 opened in the middle of the fixing plate 15;

[0031] By flipping the fixing plate 15, the fixing plate 15 drives the auxiliary rod 14 and the support block 13 to rotate. At this time, the torsion spring at the connection between the auxiliary rod 14 and the support block 13 is deformed, and the fixing column 12 is pulled out of the fixing groove 16, thereby loosening the limit on the fixing column 12, and then pulling the fixing column 12 upward, the fixing column 12 is moved out of the mounting groove 11, and the fixing column 12 drives the mounting plate 9 to move upward, so that the mounting plate 9 is disengaged from the side plate 10, thereby facilitating the disassembly and cleaning of the dustproof net 8, preventing the dustproof net 8 from being blocked by dust during long-term use, and maintaining smooth ventilation and heat dissipation.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
