Description

TECHNICAL FIELD

[0001] The utility model relates to new energy storage technical field, concretely relates to a new energy storage machine case convenient for heat dissipation. BACKGROUND

[0002] Energy storage equipment is mainly divided into power storage and heat storage, and provides power and heat energy for external equipment. The outer layer of the energy storage equipment is a machine case, which is used to protect the energy storage equipment. When the energy storage equipment is working, a large amount of heat will be released. In order to dissipate the heat, various air vents are opened on the machine case of the energy storage equipment to dissipate the heat.

[0003] For example, the utility model patent with publication (announcement) number CN214507647U and the name of "a machine case for energy storage equipment" discloses "a box body, a box cover is arranged on the upper side of the box body, the two side walls in the width direction of the box cover are both extended downward and closely attached to the outer wall of the box body, the two side walls in the length direction of the box body are both provided with a heat dissipation hole, and a heat dissipation fan is embedded in each heat dissipation hole. The heat dissipation fan is connected with a thermal switch used for opening and closing the heat dissipation fan, and the two side walls in the length direction of the box cover are both connected with a baffle downward, and there is a gap between the baffle and the outer wall of the box body." By opening the heat dissipation hole on the two side walls in the length direction of the box body and arranging the heat dissipation fan in the heat dissipation hole, the heat generated by the energy storage equipment in the box body can be quickly discharged. By arranging the box cover on the upper side of the box body, and closely attaching the two side walls in the width direction of the box cover to the outer wall of the box body, and connecting the two side walls in the length direction of the box cover with the baffle downward, the baffle can cover the heat dissipation fan, which reduces the probability of water or other impurities entering the box body from the heat dissipation fan, thereby ensuring the cleanliness and dryness of the energy storage equipment in the box body. The hot air discharged by the heat dissipation fan escapes from the gap between the baffle and the side wall of the box body, thereby ensuring the normal heat dissipation of the box body.

[0004] However, the above-mentioned machine case has the following problems in actual application. The baffle covers the heat dissipation fan, which greatly limits the heat dissipation effect.
