The term "plurality" in the present application means greater than or equal to two, and may be, for example, but not limited to, two, three, four, five, six, seven, eight, etc.

Note that, the ventilation assembly 40 shields the air inlet 31: it will be appreciated that the orthographic projection of the air inlet 31 on the surface of the vent assembly 40 facing the door panel 30 falls within the scope of the surface of the vent assembly 40 facing the door panel 30; it will also be appreciated that the vent assembly 40 is oversized relative to the air inlet 31 along the plane of extension of the door panel 30 to cover the air inlet 31.

It should be noted that the included angle between the first blocking portion 412 and the gravity direction is an obtuse angle. In other words, the first blocking portion 412 bends from an end near the door panel 30 to an end away from the door panel 30 toward a direction away from the door panel 30 and away from the gravitational force. In other words, the first blocking portion 412 is upwardly disposed.

It will be appreciated that the first direction is also parallel to the plane of extension of the door panel 30.

Optionally, a door panel 30 is rotatably connected to the case 10. Specifically, the door panel 30 may be rotatably connected to the case 10 through a rotation shaft, a hinge, or the like.

Alternatively, the energy storage module 20 may include a plurality of energy storage monomers (not shown) arranged in an array, and the plurality of energy storage monomers may be electrically connected in parallel, series-parallel, or the like. The energy storage cells may be, but are not limited to, lithium ion secondary batteries, lithium ion primary batteries, lithium sulfur batteries, sodium lithium ion batteries, sodium ion batteries or magnesium ion batteries, energy storage batteries, and the like.

In the embodiment of the application, the ventilation assembly 40 is disposed on the inner side of the door panel 30 of the energy storage cabinet 100 facing the installation space 11, so that the ventilation assembly 40 can well prevent water drops or water drops outside the energy storage cabinet 100 from drifting into the energy storage cabinet 100 along with wind, and can well avoid water accumulation in the energy storage cabinet 100, so that the energy storage cabinet 100 can achieve the IP protection level.

The term "IP protection class" is a standard established by the International Electrotechnical Commission (IEC) for measuring the protection of electronic equipment against dust and water. The IP rating is typically composed of two digits, the first representing a dust rating and the second representing a water rating.

Optionally, the plurality of air inlets 31 are arranged according to a preset rule to form an air inlet area, the door panel 30 may have a plurality of air inlet areas arranged at intervals, and each air inlet area is correspondingly provided with a ventilation assembly 40; in other words, the door panel 30 may include a plurality of air intake assemblies, and the ventilation assemblies 40 are disposed in one-to-one correspondence with the air intake areas.

Referring again to FIG. 6, in some embodiments, the angle α between the guide 411 and the first stop 412 ranges from 120 to 160. Specifically, the angle α between the guide portion 411 and the first blocking portion 412 may be, but is not limited to, 120°、122°、124°、126°、128°、130°、132°、134°、136°、138°、140°、142°、144°、146°、148°、150°、152°、154°、156°、158°、160° or the like. If the angle α between the guide portion 411 and the first blocking portion 412 is too small, the inclination of the first blocking portion 412 is insufficient, and the blocking effect on the water droplets or the water drops is reduced, so that the water droplets or the water drops easily enter the energy storage cabinet 100; the angle α between the guide portion 411 and the first blocking portion 412 is too large, so that the wind resistance of the air inlet 31 is too large, ventilation is poor, and the air cooling and heat dissipation effects of the energy storage device are reduced. When the angle α between the guide portion 411 and the first blocking portion 412 is 120 ° or more and α or less than 160 °, wind resistance can be well reduced, heat dissipation to the energy storage device can be well performed, water drops, water vapor and the like can be well blocked, and water accumulation in the energy storage device can be reduced.

Optionally, the angle β between the first barrier 412 and the second barrier 413 ranges from 60 β to 89 °. Specifically, the angle β between the first blocking portion 412 and the second blocking portion 413 may be, but is not limited to, 60 °, 62 °, 64 °, 66 °, 68 °, 70 °, 72 °, 74 °, 75 °, 76 °, 78 °, 80 °, 82 °, 84 °, 85 °,89 °, and the like. The angle β between the first blocking portion 412 and the second blocking portion 413 is too small, so that the airflow flows relatively rapidly when flowing to the second blocking portion 413, the wind resistance is relatively large, the ventilation is relatively poor, and the heat dissipation effect of the energy storage cabinet 100 is reduced; the angle β between the first blocking portion 412 and the second blocking portion 413 is too large, so that water droplets or water drops easily pass through the ventilation assembly 40 and enter the energy storage cabinet 100, so that water is easily accumulated in the energy storage cabinet 100. When the angle β between the first blocking portion 412 and the second blocking portion 413 is 60 ° or more and β is or less than 89 °, wind resistance can be well reduced, heat dissipation to the energy storage device can be well performed, water drops, water vapor and the like can be well blocked, and water accumulation in the energy storage device can be reduced.

Fig. 7 is a schematic structural view of the first barrier 41 of the embodiment of fig. 5 from another perspective. Fig. 8 is a partial view of yet another view of the first baffle 41 of the fig. 5 embodiment of the present application. Fig. 9 is an enlarged view of a broken line box II in fig. 7.

Referring to fig. 7 to 9, in some embodiments, the first baffle 41 extends along a second direction (as shown by a double arrow B in fig. 7), the second blocking portion 413 has an end face 4131 facing away from the first blocking portion 412, and the second blocking portion 413 further has a plurality of notches 4132 arranged at intervals along the second direction, and the notches 4132 penetrate the end face 4131; in a second direction, at least a portion of the notch 4132 in a location away from the end face 4131 has a dimension that is greater than the dimension of the notch 4132 at the location of the end face 4131, wherein the first direction intersects the second direction.

It will be appreciated that the second direction is parallel to the plane of extension of the door panel 30. It is also understood that the second direction is the extending direction of the first barrier 41.

Optionally, in some embodiments, the first direction is perpendicular to the second direction, the second direction being perpendicular to the direction of gravity.

In this embodiment, by providing the notch 4132 at the end of the second blocking portion 413 facing away from the first blocking portion 412, and making the size of at least a portion of the position of the notch 4132 facing away from the end face 4131 larger than the size of the position of the notch 4132 on the end face 4131, the gas-liquid mixture (such as water vapor) blown into the first baffle 41 can use the coanda effect, when striking the second blocking portion 413 of the first baffle 41, the floating droplets are more likely to adhere to the notch 4132 of the second blocking portion 413, and the notch 4132 can enable the air flow to pass quickly, so that the droplets are adsorbed on the second blocking portion 413, thereby separating the gas from the liquid, and better avoiding the water drops or water drops in the gas-liquid mixture from entering the energy storage cabinet 100.

The Coanda Effect (Coanda Effect) is also known as Coanda Effect or Coanda Effect. The fluid (water flow or air flow) changes its tendency to flow with the convex object surface from deviating from the original flow direction. When there is surface friction (also known as fluid viscosity) between the fluid and the surface of the object over which it flows, the fluid will flow along the surface of the object as long as the curvature is not large.

Fig. 10 is an enlarged view of a dashed box III in fig. 8.

Referring to fig. 10, in some embodiments, the notch 4132 includes a first sub-notch 41321 and a second sub-notch 41322 that are in communication, the first sub-notch 41321 penetrates the end face 4131, and the first sub-notch 41321 is located on a side of the second sub-notch 41322 facing away from the end face 4131; in the second direction, the maximum width of the first sub-notch 41321 is greater than the maximum width of the second sub-notch 41322.

In this embodiment, the size of the first sub-notch 41321 is larger, when the gas-liquid mixture passes through the notch 4132, the liquid drop can be better absorbed by the side wall of the first sub-notch 41321, so as to achieve better gas-liquid separation effect, in addition, the first sub-notch 41321 can also enable the gas flow to pass through the notch 4132 more rapidly, so as to improve the heat dissipation effect of the energy storage cabinet 100. In addition, the second sub-notch 41322 penetrates through the end face 4131, so that air flow can be better combed, and when the air flow flows to one side of the second blocking portion 413 away from the door plate 30, collision is avoided to form vortex, the air inlet efficiency of the energy storage cabinet 100 is affected, and the heat dissipation effect of the energy storage cabinet 100 is reduced. Furthermore, along the second direction, the maximum width of the second sub-notch 41322 is smaller than that of the first sub-notch 41321, so that the absorption effect of the side wall of the second sub-notch 41322 on the liquid drops can be improved, the gas-liquid separation effect can be better improved, and the service life of the filter plate can be prolonged.

In a specific embodiment, the first sub-notch 41321 is rectangular, and the second sub-notch 41322 is circular arc; in other words, the notch 4132 is gourd-shaped, flask-shaped, or the like. Thus, the first baffle 41 has better gas-liquid separation effect, the notch 4132 can be easily processed, and the processing cost of the notch 4132 is better reduced.

In some embodiments, a maximum dimension L1 of the first sub-notch 41321 in the second direction ranges from 2mm L1 to 4mm. Specifically, in the second direction, the maximum dimension L1 of the first sub-notch 41321 may be, but is not limited to, 2.0mm, 2.2mm, 2.4mm, 2.6mm, 2.8mm, 3.0mm, 3.2mm, 3.4mm, 3.6mm, 3.8mm, 4mm, etc. In the second direction, if the maximum dimension L1 of the first sub-notch 41321 is too large, the capillary action of the first sub-notch 41321 is reduced, and when the air flow blows through the first sub-notch 41321, the liquid in the middle of the air flow is not adsorbed, and the adsorption capacity of the first sub-notch 41321 and the side wall thereof to the liquid drops in the air flow is reduced, so that the gas-liquid separation effect of the second blocking portion 413 is reduced; in the second direction, if the maximum dimension L1 of the first sub-notch 41321 is too small, the processing difficulty of the first sub-notch 41321 is increased, and the manufacturing cost of the ventilation assembly 40 is increased; in addition, the maximum dimension L1 of the first sub-notch 41321 is too small, which reduces the air intake efficiency and reduces the heat dissipation effect of the energy storage cabinet 100. When the maximum dimension L1 of the first sub-notch 41321 is 2mm less than or equal to L1 less than or equal to 4mm along the second direction, the first sub-notch 41321 may have a good capillary force, and when the air flow blows, the liquid entrained in the air flow is adsorbed on the side wall of the first sub-notch 41321, so that the liquid does not flow through one side of the first baffle 41 away from the door panel 30, thereby having a good gas-liquid separation effect, and simultaneously, the processing difficulty of the first sub-notch 41321 may be reduced, the manufacturing cost of the ventilation assembly 40 is reduced, and the air intake is relatively large, so that the energy storage cabinet 100 has a relatively good heat dissipation efficiency.

In some embodiments, the ratio L1/L2 of the maximum width L1 of the first sub-notch 41321 to the maximum width L2 of the second sub-notch 41322 along the second direction is in the range 1.8+.l1/l2+.3.

Specifically, in the second direction, the ratio L1/L2 of the maximum width L1 of the first sub-notch 41321 to the maximum width L2 of the second sub-notch 41322 may be, but is not limited to, 1.8, 2.0, 2.2, 2.4, 2.6, 2.8, 3.0, etc.

In this embodiment, the ratio L1/L2 of the maximum width L1 of the first sub-notch 41321 to the maximum width L2 of the second sub-notch 41322 is too small, so that the maximum width L1 of the first sub-notch 41321 may be too small or the maximum width L2 of the second sub-notch 41322 may be too large, when the maximum width L1 of the first sub-notch 41321 is too small, the processing difficulty of the first sub-notch 41321 is increased, the manufacturing cost of the ventilation assembly 40 is increased, and in addition, the maximum size L1 of the first sub-notch 41321 is too small, the air intake efficiency is reduced, and the heat dissipation effect of the energy storage cabinet 100 is reduced; when the maximum width L2 of the second sub-notch 41322 is too large, the adsorption of the second sub-notch 41322 on the droplets in the airflow is reduced, and the gas-liquid separation effect is reduced. If the ratio L1/L2 of the maximum width L1 of the first sub-notch 41321 to the maximum width L2 of the second sub-notch 41322 is too large, it is possible that the maximum width L1 of the first sub-notch 41321 is too large or that the maximum width L2 of the second sub-notch 41322 is too small, when the maximum width L1 of the first sub-notch 41321 is too large, the capillary action of the first sub-notch 41321 is reduced, when the air flow blows through the first sub-notch 41321, the liquid in the middle of the air flow is not absorbed, and the absorption capability of the first sub-notch 41321 and the side wall thereof on the liquid drops in the air flow is reduced, so that the gas-liquid separation effect of the second blocking portion 413 is reduced; when the maximum width L2 of the second sub-notch 41322 is too small, the airflow flows to the side of the second blocking portion 413 away from the door panel 30, clash easily occurs to form vortex, which affects the air intake efficiency of the energy storage cabinet 100 and reduces the heat dissipation effect of the energy storage cabinet 100. When the ratio L1/L2 of the maximum width L1 of the first sub-notch 41321 to the maximum width L2 of the second sub-notch 41322 is 1.8L 1/L2 is less than or equal to 3, the energy storage cabinet 100 has high air inlet efficiency, good heat dissipation effect, good gas-liquid separation effect of the first baffles 41, water accumulation in the energy storage cabinet 100 is reduced, and service life of the filter plate in the energy storage cabinet 100 is prolonged.

Fig. 11 is a schematic structural view of a first baffle 41 according to still another embodiment of the present application. Fig. 12 is an enlarged view of a dashed box IV in fig. 11. Fig. 13 is an enlarged view of a dashed box V in fig. 12.

Referring to fig. 11 to 13, in some embodiments, the first baffle 41 further includes a burr 414, the burr 414 is disposed at an end of the second blocking portion 413 facing away from the first blocking portion 412, and the burr 414 protrudes from the second blocking portion 413 toward a side of the second blocking portion 413 facing the door panel 30.

As can be appreciated, the burrs 414 are spaced apart from the first blocking portions 412 at opposite ends of the second blocking portions 413, and the burrs 414 protrude or bend toward the same surface of the second blocking portions 413 as the first blocking portions 412.

Alternatively, the number of the burrs 414 is plural, and the plural burrs 414 are spaced apart along the second direction.

Optionally, two adjacent burrs 414 are spaced apart by the notch 4132; it will be appreciated that the notches 4132 extend through the burrs 414, and that the plurality of notches 4132 divide the elongated larger burrs 414 into a plurality of smaller sized burrs 414.

Optionally, the burr 414 of the present embodiment may be cut from the side of the second blocking portion 413 away from the door panel 30 to the side of the second blocking portion 413 facing the door panel 30 by controlling the cutting direction of the first blocking plate 41 when the first blocking plate 41 is cut, so that the burr 414 may be formed at one time in the cutting process of the first blocking plate 41, without adding an additional process, while improving the liquid blocking effect of the ventilation assembly 40, without increasing the manufacturing cost of the ventilation assembly 40.

In this embodiment, by disposing the burr 414 on the side of the second blocking portion 413 facing away from the first blocking portion 412, so that the side of the second blocking portion 413 facing away from the first blocking portion 412 is coarser and irregular, the burr 414 can further adsorb fine droplets in the gas-liquid mixture blown through the second blocking portion 413, thereby blocking the liquid on the side of the first baffle 41 facing the door panel 30, and improving the gas-liquid separation effect.

Referring to FIG. 13, in some embodiments, the height h of the burr 414 protruding from the second blocking portion 413 is in the range of 0.05 mm.ltoreq.h.ltoreq.0.2 mm. In other words, the height h of the burr 414 protruding from the surface of the second blocking portion 413 facing the door panel 30 ranges from 0.05 mm.ltoreq.h.ltoreq.0.2 mm. Specifically, the height h of the burr 414 protruding from the second blocking portion 413 may be, but is not limited to, 0.05mm, 0.06mm, 0.07mm, 0.1mm, 0.12mm, 0.14mm, 0.16mm, 0.18mm, 0.2mm, etc. In this embodiment, the height h of the burr 414 protruding from the second blocking portion 413 is too small, so that the burr 414 cannot achieve the effect of improving gas-liquid separation; the height h of the burr 414 protruding from the second blocking portion 413 is too large, so that the size of the burr 414 is too large to be formed in one step through a cutting process, and the burr 414 needs to be additionally manufactured, thereby increasing the manufacturing cost of the first baffle 41.

In some embodiments, the burr 414 gradually decreases in size from an end connecting the second blocking portion 413 to an end facing away from the second blocking portion 413. Optionally, the burr 414 is a tapered structure. Therefore, the end face 4131 of the second blocking portion 413, which deviates from the first blocking portion 412, is rougher, the gas-liquid separation effect of the first baffle 41 is better improved, the accumulated water in the energy storage cabinet 100 is reduced, the mildew probability of filter cotton is reduced, and the service life of the filter plate is prolonged.

The width w1 of the guide portion 411 directs the distance between the end of the guide portion 411 facing away from the first blocking portion 412 and the end of the guide portion 411 connecting the first blocking portion 412. The width w2 of the second blocking portion 413 refers to a distance between an end portion of the second blocking portion 413 connected to the first blocking portion 412 and an end portion of the second blocking portion 413 facing away from the first blocking portion 412.

Specifically, the ratio (w1+w2)/s of the sum of the width w1 of the guide portion 411 and the width w2 of the second blocking portion 413 to the distance s between two adjacent first blocking portions 412 along the first direction may be, but is not limited to, 0.8, 0.82, 0.84, 0.86, 0.88, 0.9, 0.92, 0.94, 0.96, 0.98, 1, etc.

In this embodiment, (w1+w2)/s is too small, so that rainwater easily passes through the ventilation assembly 40 and enters the energy storage cabinet 100, and the blocking effect of the ventilation assembly 40 on rainwater is reduced; if (w1+w2)/s is too large, the wind resistance of the ventilation assembly 40 is increased, and the ventilation capability of the ventilation assembly 40 is reduced, thereby reducing the heat dissipation effect of the energy storage cabinet 100. When (w1+w2)/s is less than or equal to 0.8 and less than or equal to 1, the ventilation assembly 40 can have higher water blocking and water isolating effects, so that the IP protection level of the ventilation assembly 40 is improved, and the phenomenon of hydrops or dropsy in the energy storage cabinet 100 is better avoided.
