The energy storage converter cabinet with a wall-mounted energy storage box includes: an outer shell 1, a plurality of partitions 4, a ventilation pipe 6, a cabinet door 2 and a plurality of air outlet pipes 3. A door opening is provided on one side of the outer shell 1.

A plurality of air outlet pipes 3 are fixed on the inner side of the cabinet door 2 in sequence and are connected to the ventilation pipe 6, and the air outlet pipes 3 correspond to the partitions 4 one by one and block the gap between the cabinet door 2 and the partitions 4; a plurality of ventilation holes 9 are provided on the ventilation pipe 6, and the ventilation holes 9 are used to cool the corresponding space.

[0029] The beneficial effect of the energy storage converter cabinet with a wall-mounted energy storage box provided by the utility model is that: compared with the prior art, the energy storage converter cabinet with a wall-mounted energy storage box provided by the utility model has a door opening on the outer shell 1, and a plurality of partitions 4 are detachably connected to the inner wall of the outer shell 1, and the energy storage unit is installed on the partition 4. A ventilation pipe 6 is hinged on the outer side surface of the outer shell 1, and the ventilation pipe 6 is located on one side of the door opening. A cabinet door 2 is fixed on the ventilation pipe 6, and the outer shell 1, the plurality of partitions 4 and the cabinet door 2 are enclosed as a plurality of spaces. A plurality of air outlet pipes 3 are fixed on the inner side surface of the cabinet door 2 and are connected to the air outlet pipe 6, and the air outlet pipe 3 blocks the gap between the cabinet door 2 and the partition 4.

[0030] In actual application, a plurality of air vents 9 are provided on the air outlet pipe 3, and the air outlet holes are connected to the space, so as to realize cooling of the energy storage units in each space. In the present application, the air outlet pipe 3 is integrated with the cabinet door 2, and the inner cavity of the shell 1 is divided into a plurality of spaces. Therefore, on the basis of improving the level of integration, the cooling treatment of each energy storage unit is realized, the service life of the energy storage unit is guaranteed, and the structure of the whole device is relatively simple.

[0031] The energy storage converter can control the charging and discharging process of the battery, perform AC / DC conversion, and directly supply power to the AC load when there is no power grid. The box-type energy storage converter is also called an energy storage box. For easy management, multiple energy storage boxes will be placed in the cabinet for use. Therefore, an energy storage converter cabinet is required.

[0032] Household wall-mounted energy storage boxes are usually used alone as household low-power energy storage devices. However, for most households, the utilization rate of wall-mounted energy storage boxes is low. In order to increase the utilization rate of wall-mounted energy storage boxes, it is considered to form a comprehensive energy storage based on multiple low-power wall-mounted energy storage boxes in parallel, so as to meet the household low-power needs while also meeting the industrial high-power energy storage needs. However, directly connecting the wall-mounted energy storage boxes in parallel will take up a large space. Therefore, the method of concentrating multiple wall-mounted energy storage boxes in the same shell 1 to form an energy storage inverter cabinet by wall-mounting is more popular. However, this wall-mounting method has low utilization rate of the internal space of the shell 1, which will waste a lot of cabinet space and cause the size of the shell 1 to be larger, and it is not conducive to heat dissipation. Especially for containers with great market potential, the space utilization rate and heat dissipation of the energy storage inverter cabinet used are the key factors determining its market prospects.

[0033] In some embodiments of the energy storage converter cabinet with a wall-mounted energy storage box provided in the present application, a plurality of U-shaped grooves are provided on the inner wall of the housing 1, and the partition 4 is plugged into and matched with the U-shaped grooves.

A card plate is installed along the length direction of the wiring groove, and the card plate is plugged into the inner wall of the housing 1. The card plate abuts against the plurality of connecting wires in the wiring groove, in order to ensure that the connecting wires can be stably positioned in the wiring groove.
