Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation of an energy storage box, and in particular to a fan used for an energy storage box. Background Art

[0002] The energy storage box is a box for storing multiple battery clusters. In order for the battery cluster to work stably in the box, the heat generated by the battery cluster needs to be discharged. At present, the commonly used heat dissipation method for energy storage boxes is to install a fan on the side of the energy storage box to dissipate heat from the inside of the energy storage box. Since the fan needs to exchange the outside air with the air in the energy storage box, dust will accumulate inside the fan. When too much dust accumulates, it will affect the use of the fan and reduce the air exchange efficiency. At this time, the inside of the fan needs to be cleaned manually.

[0003] However, the motor inside the existing fan is usually installed in the fan by screws. When cleaning the inside of the fan, the motor needs to be disassembled. For this purpose, it is necessary to find a suitable tool to loosen the screws, which is time-consuming. In addition, the internal space of the fan is relatively narrow, making cleaning very inconvenient, which greatly reduces the cleaning efficiency. Utility Model Content

After the buckle 7 completely leaves the clamping groove 14, the upper shell cover 2 can be removed, so that the shell is separated into the upper shell cover 2 and the lower shell cover 3, which is convenient for cleaning the interior of the fan and improves the cleaning efficiency; and after the upper shell is removed, the positioning block 28 lacks the pressing block 31 for pressing it, and the motor 1 can be taken out from the placement groove 16 without using tools, saving time;

[0032] After the fan is cleaned, the fan housing needs to be assembled. First, align the positioning hole 30 of the positioning block 28 with the positioning column 29 of the limit block 15 until the motor 1 is placed in the placement groove 16 of the limit block 15. Then align the upper shell cover 2 with the lower shell cover 3 and place it, and put the buckle 7 into the groove 13. Then push the upper shell cover 2 to move the undercut 6 toward the lower shell cover 3. The inclined surface of the undercut 6 will push the positioning plate 11 to move upward until the positioning groove 13 of the undercut 6 is 0 is completely located below the positioning plate 11, the positioning plate 11 is pulled into the positioning groove 10 by the elastic pulling force of the spring 25, so that the undercut is positioned and fixed, and the buckle 7 is now engaged in the clamping groove 14, and the undercut 6 and the buckle 7 are fixed by the positioning plate 11 and the clamping groove 14 respectively, so that the upper shell cover 2 is fixed on the lower shell cover 3, and the assembly of the shell is completed, and finally the filter screen plate 18 is aligned with the through hole 22 and inserted until the bottom of the filter screen plate 18 slides into the slot 19.
