[0034] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0035] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0036] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0037] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0038] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0039] According to one embodiment of the present application, an energy storage system is provided. Figures 1 to 5 As shown, the energy storage system includes a cabinet 1 and an air conditioner 2, wherein the air conditioner 2 is embedded in the cabinet 1, and a portion of the air conditioner 2 protrudes from the outer surface of the cabinet 1. A drain port 21 is provided at the portion of the air conditioner 2 protruding from the outer surface. Water in the air conditioner 2 can be directly discharged from the drain port 21 without providing a drainage pipeline in the cabinet 1, thereby preventing water from leaking into the cabinet 1.

[0040] In this example, the air conditioner 2 is embedded in the cabinet 1, and part of the air conditioner 2 protrudes from the outer surface of the cabinet 1. A drain port 21 is provided on the protruding part of the air conditioner 2, and water in the air conditioner 2 can be directly discharged through the drain port 21. The drain port 21 is located outside the cabinet 1, thereby preventing water from leaking into the cabinet 1 and improving the waterproof level of the cabinet 1. The protruding part of the air conditioner 2 in this article refers to the part of the air conditioner 2 protruding from the outer surface of the cabinet 1.

[0041] The interior of the cabinet 1 is suitable for accommodating energy storage devices such as lithium batteries. The air conditioning device 2 is installed on the side wall of the cabinet 1 and can dissipate heat from the batteries in the cabinet 1. When the air conditioning device 2 is in operation, air conditioning condensation water will be generated. For example, the air intake of the compressor, the air intake pipeline of the refrigeration system, the evaporator, the water pump, the water pipe, etc. have low temperatures. The surfaces of these low-temperature components may come into contact with wet air to produce condensation water. Alternatively, since the air conditioning device 2 needs to exchange heat with outdoor air during refrigeration, the air inlet 231 and the air outlet 232 of the air conditioning device 2 are connected to the outside world. Therefore, rainwater may enter the interior of the air conditioning device 2 when it rains. Alternatively, for liquid-cooled air conditioners, coolant leakage may occur during use. Due to leakage of pipe joints, leakage of pipe seals, attenuation of clamp torque, damage to pipes, leakage of water pumps, etc., there is a small probability of leakage.

[0042] The air conditioning condensed water, rainwater entering the air conditioning device 2, or liquid leakage inside the air conditioning device 2 can all be discharged from the air conditioning device 2 in a timely manner from the drain port 21. The present application arranges the air conditioning device 2 to protrude partially from the outer surface of the cabinet 1, and arranges the drain port 21 on the protruding portion, so that the drain port 21 is located outside the cabinet 1, thereby avoiding water leakage caused by drilling holes in the side wall of the cabinet 1 to arrange a drain pipe, resulting in insulation degradation, short circuit and other problems, and the energy storage system of the present application is safer and more reliable.

[0043] like Figure 2 As shown, in this example, the drain port 21 includes a circular hole or a square hole. For example, it can be a rectangular hole, a pentagonal hole, etc., or it can also be a circular hole, an elliptical hole or other irregularly shaped through holes. Of course, the specific shape of the drain port 21 can be determined by those skilled in the art according to actual conditions, and is not specifically limited here.

[0044] like Figure 2 As shown, in this example, the air conditioner 2 is provided with a plurality of drain ports 21 at intervals. When the amount of water inside the air conditioner 2 is large, the drainage efficiency can be improved by providing a plurality of drain ports 21, thereby preventing water from accumulating at the bottom of the air conditioner 2. Alternatively, when some of the drain ports 21 are blocked, other drain ports 21 can still function as drainage ports, thereby improving the reliability of the drain ports 21.

[0045] For example, the number of drain outlets 21 may be one, two, three or four, etc., and those skilled in the art may determine the number according to actual conditions, and no specific limitation is made herein.

[0046] Alternatively, the plurality of drain ports 21 are arranged in an array, and the size of each drain port 21 is set to be relatively small, so as to prevent foreign objects such as external insects or leaves from entering the air conditioning device 2 through the drain port 21, thereby blocking the drain port 21 or damaging the internal parts of the air conditioning device 2. Of course, the specific arrangement of the drain port 21 can be determined by those skilled in the art according to actual conditions, and is not specifically limited here.

[0047] In an example, Figure 2 As shown, the drain port 21 is located at the bottom end of the air conditioner 2. The drain port 21 is arranged at the bottom end of the air conditioner 2, that is, the drain port 21 is arranged at the bottom end of the portion of the air conditioner 2 protruding from the outer surface. Thus, the water in the air conditioner 2 can be discharged in time to avoid water accumulation.

[0048] In this example, the air conditioning device 2 can be embedded in the side wall of the cabinet 1, the air conditioning device 2 partially protrudes from the side wall of the cabinet 1, and a drainage port 21 is provided at the lower end of the protruding portion.

[0049] Or, in one example, Figure 2 and Figure 4 As shown, the cabinet 1 includes a cabinet door 11, and the air conditioner 2 is embedded in the cabinet door 11, and the air conditioner 2 partially protrudes from the outer surface of the cabinet door 11. The air conditioner 2 is installed on the cabinet door 11 for easy operation and installation.

[0050] like Figure 2 As shown, the cabinet door 11 is suitable for sealing the internal accommodating cavity of the cabinet body 1. The air conditioning device 2 can be embedded in the cabinet door 11, and partially protrudes from the outer surface of the cabinet door 11. When installing or removing the air conditioning device 2, the cabinet door 11 can be rotated to open for easy operation, saving time and effort.

[0051] In an example, Figures 3 to 5 As shown, the cabinet door 11 is provided with a mounting portion 111 penetrating in the thickness direction, and the air conditioning device 2 is passed through the mounting portion 111 and fixed to the inner wall of the mounting portion 111. The air conditioning device 2 is installed on the cabinet door 11 and penetrates the cabinet door 11. The control device can be opened together with the cabinet door 11. When the cabinet door 11 is opened, the air conditioning device 2 can be conveniently maintained on one side of the inner surface of the cabinet door 11, so there is no need to disassemble the entire air conditioning device 2, saving time and effort.

[0052] like Figure 3 and Figure 5As shown, in this example, the mounting portion 111 can be a mounting hole provided through the cabinet door 11 in the thickness direction, and the air conditioner 2 is fixed to the inner wall of the mounting hole. The air conditioner 2 can protrude from one end of the mounting hole, that is, from the outer surface of the cabinet door 11. A drain port 21 is provided at the lower end of the protruding portion of the air conditioner 2.

[0053] In this example, the air conditioner 2 can be fastened to the cabinet door 11 by fasteners such as screws or bolts. Alternatively, the air conditioner 2 can also be fastened to the cabinet door 11 by bonding or clamping. Alternatively, bolts are embedded in the inner side of the cabinet door 11, and the air conditioner is hung on the embedded bolts. Of course, the fixing method of the air conditioner 2 can be determined by those skilled in the art according to actual conditions, and no specific limitation is made here.

[0054] In one example, a seal is provided between the air conditioning device 2 and the mounting portion 111 to improve the waterproof performance of the cabinet door 11 .

[0055] For example, along the circumference of the air-conditioning device 2, a circle of sealing material is arranged at a position close to the inner wall of the air-conditioning device 2 and the mounting portion 111 to seal the gap between the air-conditioning device 2 and the cabinet door 11, thereby preventing water leakage from the gap between the air-conditioning device 2 and the cabinet door 11 and improving the waterproofness of the cabinet door 11.

[0056] The sealing member may be a rubber or plastic sealing ring, etc., and those skilled in the art may determine the sealing member based on actual conditions, and no specific limitation is made here.

[0057] In this example, sealant may be sprayed at the position of the seal along the direction of the seal, thereby further improving the waterproof performance of the cabinet door 11 .

[0058] In this example, if Figure 4 and Figure 5 As shown, the mounting portion 111 can be a rectangular hole, the outer shell 23 of the air-conditioning device 2 is a rectangular parallelepiped structure as a whole, and the size of the rectangular hole corresponds to the size of the rectangular parallelepiped, so that the air-conditioning device 2 can be stably installed in the mounting portion 111, and the gap between the air-conditioning device 2 and the inner wall of the mounting portion 111 can be easily sealed.

[0059] Of course, the mounting portion 111 may also be in other shapes, such as a circular hole, an elliptical hole or other irregularly shaped holes, etc. The shape of the mounting portion 111 may be adapted to the structure of the housing 23 of the air conditioning device 2. Those skilled in the art may determine the shape according to actual conditions, and no specific limitation is made here.

[0060] Alternatively, the mounting portion 111 may also be a mounting groove structure provided on the cabinet door 11 , and the air conditioning device 2 is embedded and installed in the mounting groove, and a portion of the air conditioning device 2 protrudes from the outer surface of the cabinet door 11 .

[0061] In one example, the protrusion length of the air conditioner 2 from the cabinet 1 is 5mm to 60mm. The air conditioner 2 partially protrudes from the outer surface of the cabinet 1, and the protrusion length of the air conditioner 2 is 5mm to 60mm, which can not only set the drain port 21 at the protruding part, but also avoid excessive protrusion and low space utilization. In addition, the air conditioner 2 is protruded from the cabinet 1, which can also ensure that the air conditioner 2 is at a safe distance from the battery inside the cabinet 1.

[0062] For example, the protruding length of the air-conditioning device 2 from the cabinet 1 can be 5mm, 10mm, 20mm, 30mm, 50mm or 60mm, etc., which can be set according to factors such as the thickness of the air-conditioning device 2, or the protruding length of the air-conditioning device 2 can be set to correspond to the size of the drain outlet 21.

[0063] Of course, the protruding length of the air conditioning device 2 from the outer surface of the cabinet 1 can be determined by those skilled in the art according to actual conditions, and no specific limitation is made here.

[0064] In an example, Figure 2 and Figure 3 As shown, the air conditioner 2 includes a bottom plate 22, and the bottom plate 22 partially protrudes from the outer surface of the cabinet 1, and the drain port 21 is located at the protruding portion of the bottom plate 22. The drain port 21 is arranged on the bottom plate 22 so that the water inside the air conditioner 2 can be discharged in time to avoid water accumulation inside the air conditioner 2.

[0065] In this example, if Figure 2 and Figure 3 As shown, the bottom plate 22 is located at the bottom of the air-conditioning device 2, and the water in the air-conditioning device 2 will directly flow down the bottom plate 22. The drain port 21 is set on the bottom plate 22, so that the water inside the air-conditioning device 2 can be discharged in time to avoid water accumulation inside the air-conditioning device 2.

[0066] In an example, Figure 3 As shown, the bottom plate 22 has a first end and a second end opposite to each other, the first end protrudes from the outer surface of the cabinet 1, the second end is located inside the cabinet 1, and the inner surface of the bottom plate 22 gradually rises from the first end to the second end. The inner surface of the bottom plate 22 is the surface located inside the air conditioning device 2. The inner surface of the bottom plate 22 gradually rises from the first end to the second end, so that water at the second end can flow smoothly to the first end, which is convenient for water to flow out from the drain port 21, so as to avoid water accumulation inside the air conditioning device 2.

[0067] like Figure 3As shown, the bottom plate 22 partially protrudes from the outer surface of the cabinet 1, and a drain port 21 is provided at the protruding portion. Let one end of the bottom plate 22 protruding from the cabinet 1 be the first end, and the other end opposite to the first end be the second end, that is, the second end is located in the cabinet 1. That is, from the first end to the second end of the bottom plate 22, the inner surface of the bottom plate 22 gradually rises, and the drain port 21 is located near the first end, so that water can flow out from the drain port 21 to avoid water accumulation at the bottom of the air conditioner 2.

[0068] In an example, Figure 3 As shown, the inner surface of the bottom plate 22 is an inclined surface. The inclined surface gradually slopes upward from the first end to the second end so that water can flow to the drain port 21. The inclined surface is easy to process.

[0069] Of course, the inner surface of the bottom plate 22 may also be an arc-shaped surface, etc. Those skilled in the art may determine it according to actual conditions, and no specific limitation is made here.

[0070] In an example, Figure 3 As shown, the angle between the inner surface of the bottom plate 22 and the horizontal plane is 5° to 30°. By setting the bottom plate 22 at an inclination angle of 5° to 30°, the bottom plate 22 can be tilted in the direction toward the drain port 21 so that water flows toward the drain port 21, that is, the drainage requirements of the present application can be met. It can also avoid problems such as the bottom plate 22 being too inclination angle, which leads to inconvenience during installation, or the inclination angle being too large, which affects the internal space of the air conditioning device 2.

[0071] like Figure 3 As shown, in this example, the angle between the inner surface of the bottom plate 22 and the horizontal plane is α, and α satisfies 5°≤α≤30°. For example, α can be 5°, 10°, 20°, 25° or 30°, etc., and those skilled in the art can determine it according to actual conditions, and no specific limitation is made here.

[0072] like Figure 3 As shown, in this example, the bottom plate 22 can be fixed to the air conditioner 2 in an inclined state as a whole. That is, the inner surface of the bottom plate 22 can be gradually raised from the first end to the second end.

[0073] Alternatively, in this example, the inner surface of the bottom plate 22 may be inclined, and the outer surface of the bottom plate 22 opposite to the inner surface may be horizontally arranged. That is, the inner surface of the bottom plate 22 may be inclined with a slope, and the slope may be inclined downward in the direction toward the drain port 21, so that water may flow smoothly toward the drain port 21. The outer surface of the bottom plate 22 may be horizontally arranged, so that the air conditioner 2 may be placed on the ground or on a table, etc., and when the air conditioner 2 is installed, it may also be convenient to fix the bottom of the air conditioner 2 to the inner wall of the installation portion 111.

[0074] Alternatively, in this example, the bottom plate 22 may be fixed to the air conditioner 2 in a horizontal state, and the inner wall of the mounting portion 111 corresponding to the bottom plate 22 may be tilted. When the air conditioner 2 is mounted on the mounting portion 111, the air conditioner 2 is kept tilted, so that the bottom plate 22 can be kept tilted, that is, the inner surface of the bottom plate 22 is kept tilted, and the bottom plate 22 can be tilted downward in the direction toward the drain port 21, so that water can flow smoothly to the drain port 21.

[0075] Of course, the specific setting of the inclination mode of the inner surface of the bottom plate 22 can be determined by those skilled in the art according to actual conditions, and no specific limitation is made here.

[0076] In one example, the energy storage system further includes a filter, which is installed on the air conditioning device 2 and covers the drain port 21. The filter covers the drain port 21, and water inside the air conditioning device 2 can flow out from the filter, while the filter can prevent foreign objects such as insects or leaves from entering the air conditioning device 2 from the drain port 21, thereby blocking the drain port 21 or damaging the internal parts of the air conditioning device 2.

[0077] In this example, the filter screen may be made of metal mesh, or non-metallic material, such as plastic mesh, etc. Of course, the filter screen may be determined by those skilled in the art according to actual conditions, and no specific limitation is made here.

[0078] Alternatively, in this example, the filter screen may also be a grille structure, by arranging a grille cover at one end of the drain outlet 21 .

[0079] In an example, Figure 1 Shown and Figure 2 The air conditioning device 2 includes a shell 23, and a portion of the shell 23 protrudes from the outer surface of the cabinet 1. An air inlet 231 and an air outlet 232 are provided on the protruding portion of the shell 23. The air inlet 231 is located at the lower side of the air outlet 232, and the air inlet 231 is connected to the drain port 21.

[0080] like Figure 1 and Figure 2 As shown, in this example, the air conditioning device 2 includes a housing 23, and the interior of the housing 23 is suitable for assembling equipment such as a compressor and a condenser. The bottom plate 22 is installed at the bottom of the housing 23. The housing 23 partially protrudes from the outer surface of the cabinet 1. The protruding portion on the housing 23 is provided with an air inlet 231 and an air outlet 232, and the air inlet 231 and the air outlet 232 are external circulation, that is, the air inlet 231 and the air outlet 232 can connect the housing 23 with the outside, which is suitable for heat dissipation of the components in the housing. The air inlet 231 and the air outlet 232 are arranged on the protruding portion, so that the air inlet 231 and the air outlet 232 are smooth in air inlet and outlet, which is conducive to heat dissipation.

[0081] For example, Figure 1 and Figure 2 As shown, the air inlet 231 is located at the lower side of the air outlet 232, and the air inlet 231 is connected to the drain port 21. That is, when the drain port 21 is blocked, the water in the air conditioning device 2 cannot be discharged from the drain port 21. Alternatively, when the water flow in the air conditioning device 2 is too large and cannot be discharged from the drain port 21 in time, when the water accumulates at the position of the air inlet 231, the water can be discharged from the air inlet 231 to avoid damaging the internal parts of the air conditioning device 2.

[0082] Furthermore, the air inlet 231 enters with a relatively low temperature cold air, and the air outlet 232 flows out with a relatively high temperature hot air. Since hot air usually flows upward, the air inlet 231 is arranged below the air outlet 232 to prevent the hot air flowing out of the air outlet 232 from interfering with the air inlet 231, thereby affecting the heat dissipation effect.

[0083] In one example, the air conditioning device 2 includes an outer shell 23, which partially protrudes from the outer surface of the cabinet, and an air inlet 231 and an air outlet 232 are provided on the protruding portion of the outer shell 23. The air outlet 232 is located at the lower side of the air inlet 231, and the air outlet 232 is connected to the drain port 21.

[0084] That is, the air outlet 232 may be disposed below the air inlet 231, and the air outlet 232 is connected to the drain port 21. When water that cannot be discharged from the drain port 21 accumulates at the position of the air outlet 232, it can be discharged from the air outlet 232.

[0085] In this example, if Figure 1 As shown, the lower air inlet 231 is a hexagonal structure, and the upper air outlet 232 is a square structure. Of course, the air inlet 231 and the air outlet 232 can also be other shapes, such as circular, diamond, rectangular or other irregular shapes, etc. Those skilled in the art can determine according to actual conditions, and no specific limitation is made here.

[0086] In this example, the air inlet 231 and the air outlet 232 are also provided with grilles, and the grille covers are provided at the air inlet 231 and the air outlet 232. Alternatively, the grilles are installed on the inner walls of the air inlet 231 and the air outlet 232 to prevent external impurities such as insects or leaves from entering the interior of the air conditioning device 2 through the air inlet 231 and the air outlet 232.

[0087] The sizes of the air inlet 231 and the air outlet 232 only need to meet the requirements of smooth air inlet and outlet and facilitate heat dissipation. Those skilled in the art may determine the sizes based on actual conditions and are not specifically limited here.

[0088] like Figure 4As shown, in this example, the air conditioner 2 is further provided with a connection terminal 24 and a liquid injection port 25 at a position located inside the cabinet door 11. When the cabinet door 11 is opened, the air conditioner 2 can be connected to a power source through the connection terminal 24. Coolant can be injected into the cooling pipeline through the liquid injection port 25.

[0089] The above embodiments focus on the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.
