Description

Technical Field

[0001] The present application belongs to the field of energy storage equipment, and specifically relates to an air duct drainage device for an energy storage cabinet. Background Art

[0002] Energy storage cabinets are electrical cabinets used to store electrical energy. Several battery modules are installed inside the energy storage cabinets to store electrical energy generated by solar energy, wind energy, etc. or directly store electrical energy. They play an important role in energy storage in the industrial and household fields. When conventional electricity faces unexpected accidents, power outages, or power grid repairs, the energy storage cabinets can quickly activate battery modules as backup power sources to ensure the continuity and stability of industrial production and household electricity use.

[0003] When the energy storage cabinet is supplying power, the battery module will generate a large amount of heat energy. If the heat energy cannot be effectively dissipated, the temperature inside the energy storage cabinet will rise sharply, affecting the normal use of the energy storage cabinet and even causing a fire. In winter, the energy storage cabinet located outdoors will drop to below zero with the ambient temperature. Too low a temperature inside the cabinet will reduce the conversion efficiency of the battery module. Therefore, in order to keep the battery module of the energy storage cabinet in normal working condition, it is very important to maintain the temperature inside the energy storage cabinet within a certain temperature range.

[0004] In order to maintain the temperature inside the energy storage cabinet, an industrial air conditioner can be installed on the outer box of the energy storage cabinet, and an air inlet is set on the cabinet body of the energy storage cabinet. The air outlet of the air conditioner is connected to the air inlet. According to the monitored temperature inside the energy storage cabinet, the air conditioner cools the inside of the energy storage cabinet with cold air and heats the inside of the energy storage cabinet with hot air, so that the temperature inside the energy storage cabinet is maintained within a suitable working temperature range. However, since the battery modules inside the energy storage cabinet are densely distributed, the cold and hot air of the air conditioner cannot be evenly blown to each battery module, resulting in poor temperature uniformity of the battery modules at different positions in the cabinet.

The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0027] like Figure 1 As shown, the present application discloses an energy storage cabinet air duct drainage device, including a drainage top plate 1 and a plurality of drainage side plates 2, the drainage side plates 2 are distributed along the periphery of the drainage top plate 1 and the cavity formed by the plurality of drainage side plates 2 is trumpet-shaped, so that the cross-sectional area of ​​the cavity surrounded by the drainage side plates 2 gradually increases in the direction away from the drainage top plate 1, and a plurality of drainage grooves 3 are distributed on the drainage top plate 1, and a plurality of drainage grooves 3 are distributed on the drainage side plates 2. The drainage grooves 3 on the top drainage plate 1 and the side drainage plates 2 are on different planes, so that the cold and hot air blown in from the air inlet of the air conditioner converge and flow in different directions after passing through the drainage grooves 3 on the air duct drainage device, causing air disturbance, better mixing of cold and hot air, and making the battery modules at different positions reach uniform temperature faster.

[0028] The drainage top plate 1 and the drainage side plates 2 are integrally processed and formed into an air duct drainage device of the energy storage cabinet. The integral molding process reduces the processing steps and reduces the processing difficulty of the air duct drainage device.

[0029] It should be noted that the drainage grooves 3 distributed on the drainage top plate 1 and the drainage side plates 2 include strip drainage grooves, arc-shaped drainage grooves and wave-shaped drainage grooves. The above-mentioned drainage grooves of different shapes can all divert the cold and hot air blown in from the air inlet of the air conditioner, and the above-mentioned drainage grooves 3 of different shapes can be used in combination on the drainage top plate 1 and the drainage side plates 2, respectively, so that the airflow passing through the drainage grooves of different shapes forms turbulence, thereby intensifying the mixing of the cold and hot air of the air conditioner in the cabinet.

[0030] like Figure 1 and Figure 2 As shown, in some embodiments, the drainage top plate 1 is a rectangular drainage top plate, and the drainage side plate 2 connected to the rectangular drainage top plate is a trapezoidal drainage side plate. Two groups of drainage grooves 3 of different shapes are distributed on the rectangular drainage top plate, one group of drainage grooves is an arc-shaped drainage groove, and the other group of drainage grooves is a strip-shaped drainage groove. The combined use of the arc-shaped drainage groove and the strip-shaped drainage groove makes the airflow form turbulence, which intensifies the mixing of the cold and hot air of the air conditioner in the cabinet. The drainage grooves 3 on the trapezoidal drainage side plate are equidistantly distributed.

[0031] In other embodiments, the drainage top plate 1 is an elliptical drainage top plate, and the drainage side plate 2 connected to the elliptical drainage top plate is a fan-shaped drainage side plate. The fan-shaped drainage side plate has no turning surface, and the drainage grooves 3 are evenly distributed in a radial shape from the periphery of the elliptical drainage top plate to the outermost edge of the fan-shaped drainage side plate. More drainage grooves 3 can be arranged to make the cold and hot airflows of the air conditioner more evenly dispersed.

[0032] The energy storage cabinet air duct drainage device also includes two fixing plates 4, which are relatively connected to the outermost ends of the drainage side plates 2. Figure 2 As shown, the fixing plate 4 is connected to the outermost ends of the opposite trapezoidal drainage side plates 2; in other embodiments, the fixing plate 4 is connected to the outermost ends of the fan-shaped drainage side plates that are the farthest apart.

[0033] The fixing plate 4 is evenly provided with fixing holes 5 , and the fixing holes 5 are provided with fixing bolts for fixing the fixing plate 4 at the air inlet of the energy storage cabinet.

[0034] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
