The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

In order to simplify the disclosure of the present disclosure, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present disclosure. In addition, the present disclosure may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0036] The energy storage system according to an embodiment of the present disclosure is described below with reference to FIG1 to FIG5 .

[0037] As shown in FIG. 1 and FIG. 5 , the energy storage system according to an embodiment of the present disclosure includes: a cabinet 1 and an air conditioning device 2 .

[0038] Air conditioner 2 is mounted on cabinet 1, with a portion of air conditioner 2 protruding from the outer surface of cabinet 1. A drain port 21 is provided on the portion of air conditioner 2 protruding from the outer surface. Water within air conditioner 2 can be drained directly from drain port 21, eliminating the need for drainage piping within cabinet 1 and preventing water from leaking into cabinet 1.

[0039] In this embodiment, 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 on the protruding portion of the air conditioner 2, through which water in the air conditioner 2 can be directly discharged. 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 portion of the air conditioner 2 herein refers to the portion of the air conditioner 2 that protrudes from the outer surface of the cabinet 1.

[0040] 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 pipe of the refrigeration system, the evaporator, the water pump, the water pipe, etc. are at a low temperature. The surfaces of these low-temperature components may come into contact with wet air and thus generate condensation water. Alternatively, since the air conditioning device 2 needs to exchange heat with the outdoor air during cooling, 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. There is a small probability of leakage due to leakage of pipe joints, leakage of pipe seals, attenuation of clamp torque, damage to pipes, leakage of water pumps, etc.

[0041] The aforementioned air conditioning condensate, rainwater entering the air conditioning unit 2, or liquid leakage from the air conditioning unit 2 can all be promptly and smoothly discharged from the air conditioning unit 2 through the drain port 21. By providing a portion of the air conditioning unit 2 protruding from the outer surface of the cabinet 1 and providing the drain port 21 on the protruding portion, so that the drain port 21 is located outside the cabinet 1, the present disclosure can avoid leakage caused by drilling holes in the side wall of the cabinet 1 to install a drain pipe, which can lead to problems such as insulation degradation and short circuits. The energy storage system of the present disclosure is safer and more reliable.

[0042] As shown in FIG2 , in this embodiment, the drain outlet 21 comprises a circular or square hole. For example, it may be a rectangular hole, a pentagonal hole, or a circular hole, an elliptical hole, or other irregularly shaped through-hole. Of course, the specific shape of the drain outlet 21 can be determined by those skilled in the art based on actual circumstances and is not specifically limited here.

[0043] As shown in Figure 2, in this embodiment, the air conditioner 2 is provided with multiple drain outlets 21 at intervals. When the amount of water inside the air conditioner 2 is large, the provision of multiple drain outlets 21 can improve drainage efficiency and prevent water from accumulating at the bottom of the air conditioner 2. Alternatively, if some drain outlets 21 are blocked, the remaining drain outlets 21 can still function, thereby improving the reliability of the drain outlets 21.

[0044] For example, the number of drain outlets 21 may be one, two, three or four, and those skilled in the art may determine the number based on actual conditions, which is not specifically limited here.

[0045] Alternatively, multiple drain openings 21 are arranged in an array, with each drain opening 21 being relatively small to prevent foreign matter such as insects or leaves from entering the air conditioning unit 2 through the drain opening 21, thereby blocking the drain opening 21 or damaging internal components of the air conditioning unit 2. Of course, the specific arrangement of the drain openings 21 can be determined by those skilled in the art based on actual circumstances and is not specifically limited herein.

[0046] In some embodiments, as shown in FIG2 , a drain port 21 is located at the bottom end of the air conditioning unit 2. Disposing the drain port 21 at the bottom end of the air conditioning unit 2, that is, at the bottom end of the portion of the air conditioning unit 2 that protrudes from the outer surface, allows water in the air conditioning unit 2 to be drained promptly, preventing water accumulation.

[0047] In this embodiment, the air conditioning device 2 can be embedded in the side wall of the cabinet 1, with the air conditioning device 2 partially protruding from the side wall of the cabinet 1, and a drain outlet 21 is provided at the lower end of the protruding portion.

[0048] Alternatively, in some embodiments, as shown in Figures 2 and 4, the cabinet 1 includes a cabinet door 11, and the air conditioning device 2 is embedded in the cabinet door 11, and the air conditioning device 2 partially protrudes from the outer surface of the cabinet door 11. The air conditioning device 2 is installed in the cabinet door 11 for easy operation and installation.

[0049] As shown in Figure 2, cabinet door 11 is adapted to seal the internal accommodating cavity of cabinet body 1. Air conditioning unit 2 can be embedded in cabinet door 11, with a portion protruding from the outer surface of cabinet door 11. When installing or removing the air conditioning unit 2, cabinet door 11 can be rotated open for easier operation, saving time and effort.

[0050] In some embodiments, as shown in Figures 3 to 5 , the cabinet door 11 is provided with a mounting portion 111 extending through the cabinet door 11 in the thickness direction. The air conditioning unit 2 is inserted through the mounting portion 111 and fixed to the inner wall of the mounting portion 111. The air conditioning unit 2 is mounted on the cabinet door 11 and extends through the cabinet door 11. The control device can be opened along with the cabinet door 11. Opening the cabinet door 11 allows for convenient maintenance of the air conditioning unit 2 from one side of the inner surface of the cabinet door 11, eliminating the need to disassemble the entire air conditioning unit 2, saving time and effort.

[0051] As shown in Figures 3 and 5 , in this embodiment, the mounting portion 111 can be a mounting hole formed through the thickness of the cabinet door 11, with the air conditioner 2 secured 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 outlet 21 is provided at the lower end of the protruding portion of the air conditioner 2.

[0052] In this embodiment, the air conditioner 2 can be fastened to the cabinet door 11 using fasteners such as screws or bolts. Alternatively, the air conditioner 2 can be fastened to the cabinet door 11 by bonding or snapping. Alternatively, bolts can be embedded inside the cabinet door 11, and the air conditioner can be hung on the embedded bolts. Of course, the method for securing the air conditioner 2 can be determined by those skilled in the art based on actual circumstances and is not specifically limited here.

[0053] In some embodiments, 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 .

[0054] For example, along the circumference of the air-conditioning device 2, a circle of sealing material is provided 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.

[0055] The sealing member may be a rubber or plastic sealing ring, etc. Those skilled in the art may determine the sealing member according to the actual situation, and no specific limitation is made here.

[0056] In this embodiment, sealant may be sprayed at the position of the sealing member along the direction of the sealing member, thereby further improving the waterproof performance of the cabinet door 11 .

[0057] In this embodiment, as shown in Figures 4 and 5, 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 it is convenient to seal the gap between the air-conditioning device 2 and the inner wall of the mounting portion 111.

[0058] Of course, the mounting portion 111 may also be in other shapes, such as a circular hole, an elliptical hole, or a hole of other irregular shapes. 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.

[0059] Alternatively, the mounting portion 111 may be a mounting groove structure provided on the cabinet door 11 , and the air conditioning device 2 is embedded in the mounting groove, with a portion of the air conditioning device 2 protruding from the outer surface of the cabinet door 11 .

[0060] In some embodiments, the protrusion of the air conditioner 2 from the cabinet 1 is 5 mm to 60 mm. The air conditioner 2 partially protrudes from the outer surface of the cabinet 1, and the protrusion is 5 mm to 60 mm. This allows the drain outlet 21 to be located in the protruding portion while avoiding excessive protrusion that would result in low space utilization. Furthermore, positioning the air conditioner 2 protruding from the cabinet 1 ensures a safe distance between the air conditioner 2 and the batteries inside the cabinet 1.

[0061] For example, the protruding length of the air-conditioning device 2 from the cabinet body 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.

[0062] 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 is not specifically limited here.

[0063] In some embodiments, as shown in Figures 2 and 3, the air conditioning unit 2 includes a bottom plate 22, which partially protrudes from the outer surface of the cabinet 1, and a drain port 21 is located on the protruding portion of the bottom plate 22. The drain port 21 is provided on the bottom plate 22 so that water inside the air conditioning unit 2 can be drained out in a timely manner to avoid water accumulation inside the air conditioning unit 2.

[0064] In this embodiment, as shown in Figures 2 and 3, 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.

[0065] In some embodiments, as shown in FIG3 , the bottom plate 22 has opposing first and second ends. The first end protrudes from the exterior surface of the cabinet 1, while the second end is located within the cabinet 1. 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 unit 2. The inner surface of the bottom plate 22 gradually rises from the first end to the second end to allow water at the second end to flow smoothly toward the first end, thereby facilitating water outflow from the drain port 21 and preventing water accumulation within the air conditioning unit 2.

[0066] As shown in Figure 3, the bottom plate 22 partially protrudes from the outer surface of the cabinet 1, and a drain outlet 21 is provided in the protruding portion. The end of the bottom plate 22 protruding from the cabinet 1 is referred to as the first end, and the end opposite the first end is referred to as the second end, i.e., the second end is located within the cabinet 1. In other words, the inner surface of the bottom plate 22 gradually rises from the first end to the second end, and the drain outlet 21 is located near the first end, allowing water to flow out of the drain outlet 21 and preventing water from accumulating at the bottom of the air conditioner 2.

[0067] In some embodiments, as shown in FIG3 , 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 toward the drain port 21. The inclined surface is easy to process.

[0068] 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.

[0069] In some embodiments, as shown in FIG3 , the inner surface of the bottom plate 22 is angled with the horizontal plane at a range of 5° to 30°. Setting the bottom plate 22 at a 5° to 30° angle allows the bottom plate 22 to tilt toward the drain outlet 21, facilitating water flow toward the drain outlet 21 and thus meeting the drainage requirements of the present disclosure. This also avoids problems such as excessively large inclinations of the bottom plate 22, which could lead to installation inconvenience, or excessively large inclinations that could affect the internal space of the air conditioning unit 2.

[0070] As shown in FIG3 , in this example, the angle α between the inner surface of the bottom plate 22 and the horizontal plane is set to 5°≤α≤30°. For example, α can be 5°, 10°, 20°, 25°, or 30°, etc. Those skilled in the art can determine this according to actual circumstances, and this is not specifically limited here.

[0071] As shown in Fig. 3, in this embodiment, 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.

[0072] Alternatively, in this embodiment, the inner surface of the bottom plate 22 can be inclined, while the outer surface of the bottom plate 22, which is opposite the inner surface, is horizontal. Specifically, the inner surface of the bottom plate 22 is inclined, and the slope is downwardly inclined toward the drain outlet 21, which also allows water to flow smoothly toward the drain outlet 21. The horizontal outer surface of the bottom plate 22 facilitates placement of the air conditioner 2 on the floor or a tabletop, and also facilitates securing the bottom of the air conditioner 2 to the inner wall of the mounting portion 111 during installation.

[0073] Alternatively, in this embodiment, the bottom plate 22 may be fixed to the air conditioner 2 in a horizontal position, while 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 tilted, thereby maintaining the bottom plate 22 tilted. That is, the inner surface of the bottom plate 22 is tilted, and the bottom plate 22 is tilted downward toward the drain outlet 21, allowing water to flow smoothly toward the drain outlet 21.

[0074] Of course, the specific setting of the inclination of the inner surface of the bottom plate 22 can be determined by those skilled in the art according to actual conditions and is not specifically limited here.

[0075] In some embodiments, the energy storage system further includes a filter screen, which is mounted on the air conditioning unit 2 and covers the drain outlet 21. The filter screen covers the drain outlet 21, allowing water inside the air conditioning unit 2 to flow out through the filter screen. The filter screen also prevents foreign matter such as insects or leaves from entering the air conditioning unit 2 through the drain outlet 21, thereby blocking the drain outlet 21 or damaging internal components of the air conditioning unit 2.

[0076] In this embodiment, the filter screen can be made of metal mesh, or made of non-metallic material, such as plastic mesh, etc. Of course, those skilled in the art can determine the filter screen according to actual conditions, and no specific limitation is made here.

[0077] Alternatively, in this embodiment, the filter screen may also be a grille structure, by arranging a grille cover at one end of the drain outlet 21 .

[0078] In some embodiments, as shown in Figures 1 and 2, the air-conditioning device 2 includes a shell 23, which partially 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 on the lower side of the air outlet 232, and the air inlet 231 is connected to the drain outlet 21.

[0079] As shown in Figures 1 and 2, in this embodiment, the air conditioning device 2 includes a housing 23, the interior of which is suitable for assembling equipment such as a compressor and a condenser. The base plate 22 is mounted on the bottom of the housing 23. The housing 23 partially protrudes from the outer surface of the cabinet 1. The protruding portion of the housing 23 is provided with an air inlet 231 and an air outlet 232. The air inlet 231 and the air outlet 232 are for external circulation, that is, the air inlet 231 and the air outlet 232 can connect the housing 23 with the outside and are suitable for dissipating heat from the components inside the housing. The air inlet 231 and the air outlet 232 are arranged on the protruding portion to facilitate smooth air inflow and outflow, which is beneficial to heat dissipation.

[0080] For example, as shown in Figures 1 and 2, the air inlet 231 is located below the air outlet 232 and is connected to the drain outlet 21. That is, if the drain outlet 21 is blocked, water within the air conditioning unit 2 cannot be drained from the drain outlet 21. Alternatively, if the water flow within the air conditioning unit 2 is too large to be drained from the drain outlet 21 in a timely manner, if water accumulates at the air inlet 231, it can be drained from the air inlet 231 to avoid damaging the internal components of the air conditioning unit 2.

[0081] Furthermore, the air inlet 231 allows cooler air to enter, while the air outlet 232 allows hotter air to flow out. Since hot air generally flows upward, placing the air inlet 231 below the air outlet 232 prevents the hot air flowing out of the air outlet 232 from interfering with the air inlet 231, thereby affecting the heat dissipation effect.

[0082] In some embodiments, the air conditioning device 2 includes an outer shell 23, which partially protrudes from the outer surface of the cabinet. An air inlet 231 and an air outlet 232 are provided on the protruding part of the outer shell 23. The air outlet 232 is located on the lower side of the air inlet 231, and the air outlet 232 is connected to the drain outlet 21.

[0083] That is, the air outlet 232 may be provided below the air inlet 231 and 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.

[0084] In this embodiment, as shown in FIG1 , 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 may also have other shapes, such as circular, diamond, rectangular, or other irregular shapes. Those skilled in the art may determine the shape based on actual conditions, and no specific limitation is imposed herein.

[0085] In this embodiment, the air inlet 231 and the air outlet 232 are further provided with grilles, and grille covers are provided on 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.

[0086] 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 can determine them according to actual conditions and are not specifically limited here.

[0087] As shown in Figure 4, in this embodiment, the air conditioner 2 is further provided with a connection terminal 24 and a liquid filling port 25 located inside the cabinet door 11. When the cabinet door 11 is opened, the air conditioner 2 can be connected to a power source, etc., via the connection terminal 24. Coolant can be injected into the cooling pipes through the liquid filling port 25.
