Description

Technical Field

[0001] The utility model relates to the technical field of energy storage equipment, and in particular to a waterproof case for a mobile energy storage equipment and the mobile energy storage equipment. Background Art

[0002] At present, with the widespread application of renewable energy and the increasing demand for energy independence in households, the market demand for household energy storage equipment is also growing. However, existing household energy storage equipment has some shortcomings in terms of waterproof performance. Basically, the top of the energy storage cabinet is set as a sealed top, and a slope is set on the top to prevent water accumulation. Since some household energy storage equipment must have mesh holes on the top for heat dissipation, the solution of setting a slope on the top cannot be waterproof, resulting in water easily entering the interior of the device, affecting the normal use and service life of the device.

[0003] Therefore, how to design a waterproof chassis for mobile energy storage equipment that can achieve waterproofness while opening a heat dissipation mesh hole on the top of the device to ensure that water does not enter the interior of the device has become a problem that needs to be solved urgently. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art or related technology.

[0005] To this end, a first aspect of the utility model provides a waterproof chassis for a mobile energy storage device.

[0006] A second aspect of the utility model provides a mobile energy storage device.

[0007] In view of this, the first aspect of the utility model proposes a waterproof chassis for a mobile energy storage device, comprising: a shell; a drainage hole, arranged on the side wall of the shell; a water guide assembly, arranged on the inner wall of the shell and connected to the drainage hole; a heat sink, arranged inside the shell and located between the top of the shell and the water guide assembly, the heat sink is used for heat dissipation and is constructed to be able to guide water into the water guide assembly.

[0008] The utility model provides a waterproof case for a mobile energy storage device, comprising a housing, a drain hole, a water guide assembly and a heat sink. The heat sink can dissipate heat, and the heat sink is also constructed to be able to guide water into the water guide assembly. The drain hole is arranged on the side wall of the housing, and the water guide assembly is arranged on the inner side wall of the housing and is connected to the drain hole, so that the water can be drained to the drain hole through the water guide assembly. The heat sink is arranged in the housing and is located between the top of the housing and the water guide assembly, so that the water can be drained into the water guide assembly through the heat sink, and then the drainage function is realized through the water guide assembly. By arranging the heat sink between the top of the housing and the water guide assembly, not only can the heat sink be used for drainage, but also because the heat sink is arranged close to the top and can contact with water, it is also conducive to improving the heat dissipation effect of the heat sink. Specifically, when the heat sink is used for heat dissipation, the circuit assembly inside the housing and the parts that need to be dissipated can be arranged on the side of the heat sink away from the top of the housing, so that heat dissipation can be achieved and rainwater can be prevented from eroding the circuit assembly and the parts that need to be dissipated. It is understandable that some devices in the related art must have heat dissipation holes on the top, so when it rains, rainwater will enter the inside of the device through the heat dissipation holes, causing the device to short-circuit or be damaged. Therefore, the present application sets a water guide component on the side wall inside the shell and uses a heat sink for drainage, so that the rainwater entering the inside of the device can be guided and discharged, thereby avoiding the problem of rainwater affecting the device.

[0009] The mobile energy storage device may include an inverter and a battery module, and the heat sink is used to dissipate heat from the inverter and the battery module.

[0010] The waterproof case for mobile energy storage equipment provided by the utility model may also have the following additional technical features:

[0011] In some technical solutions, the water guide component can be optionally arranged relative to the heat dissipation holes arranged on the top of the housing, so that the water guide component can be arranged in a targeted manner to improve the drainage effect of the water guide component.

[0012] In some technical solutions, optionally, the heat sink includes: a plurality of heat sink fins, any two adjacent heat sink fins form a drainage portion, and the drainage portion is used to guide water into the water guide assembly.

[0013] In this technical solution, the heat dissipation effect of the heat sink can be improved by providing the heat dissipation fins, and the heat dissipation fins also form a drainage portion for drainage, further improving the heat dissipation effect of the heat sink. It is understandable that when water flows in the drainage portion, it will take away part of the heat of the heat sink, thus improving the heat dissipation effect of the heat sink.

[0014] In some technical solutions, optionally, the drainage portion may be in the form of a drainage groove, and the drainage groove may be formed by heat dissipation fins of a heat dissipation element.

[0015] In some technical schemes, optionally, the water guide component includes: a flow guide member, which is arranged on the inner wall of the shell; a flow baffle member, which is arranged on the flow guide member or the heat sink; and a water guide groove, which is surrounded by the flow guide member, the flow baffle member and the inner wall of the shell and is connected to the drainage hole.

[0016] In this technical solution, the water guide assembly includes a flow guide, a flow baffle and a water guide groove. The flow baffle, the flow guide and the inner side wall of the shell together form a water guide groove, so that water can be guided to the drain hole through the water guide groove for discharge. Specifically, the flow baffle can be arranged on the flow guide, or on a heat sink arranged between the water guide assembly and the top of the shell, so that the flow guide and the flow baffle can form a water guide groove with the inner side wall of the shell, and water can be discharged from the drain hole through the water guide groove.

[0017] In some technical solutions, the flow guide includes ribs formed on the inner wall of the shell.

[0018] In some technical solutions, optionally, the waterproof chassis for the mobile energy storage device further includes: a mounting groove, which is arranged on the heat sink, and the baffle is arranged in the mounting groove.

[0019] In the technical solution, the waterproof case for the mobile energy storage device further includes a mounting groove. The mounting groove is arranged on the heat sink, so that the baffle can be arranged in the mounting groove. Specifically, the mounting groove is arranged on a side of the heat sink close to the water guide component, so that when the baffle is arranged in the mounting groove, the baffle and the guide can be surrounded by the inner side wall of the housing to form a water guide groove.

[0020] In some technical solutions, optionally, the flow blocking member is an elastic flow blocking member or a non-elastic flow blocking member.

[0021] In this technical solution, the baffle is an elastic baffle or a non-elastic baffle. The elastic baffle is elastic, so the sealing of the water guide groove formed by the elastic baffle is good, and the size of the formed water guide groove can also be adjusted, which improves the user's use requirements. The non-elastic baffle has a long service life and is relatively stable, so it can improve the water guiding effect of the water guide groove.

[0022] In some technical solutions, optionally, the water guiding component includes an annular water guiding component, and the annular water guiding component is arranged along the circumferential direction of the inner side wall of the shell.

[0023] In this technical solution, the water guide assembly includes an annular water guide assembly, and the annular water guide assembly is arranged along the circumferential direction of the inner side wall of the shell. It can be understood that the annular water guide assembly is similar to a hollow assembly in the shape of a flange, so that when the annular water guide assembly is arranged along the circumferential direction of the inner side wall of the shell, the middle part can flow out, so that other parts such as circuit components can be arranged in this part of the space, and a certain space is reserved for the arrangement of other parts.

[0024] In some technical solutions, optionally, the heat sink is disposed on the annular water guiding assembly, and a gap is provided between the heat sink and the inner side wall of the shell.

[0025] In this technical solution, the heat sink can be arranged on the annular water guide assembly, which facilitates the installation and fixation of the heat sink. At the same time, in order to further fix the heat sink, a certain gap can be reserved between the heat sink and the inner side wall of the shell, thereby facilitating the adjustment of the heat sink and improving the installation efficiency of the heat sink.

[0026] In some technical solutions, optionally, the waterproof chassis for the mobile energy storage device further includes: a sealing member, which is arranged in a partial area of ​​the gap.

[0027] In this technical solution, when a gap is left between the heat sink and the inner wall of the shell, it is convenient to install the heat sink, but some water will flow into the shell through the gap. Therefore, by setting a seal to seal part of the gap, water can be prevented from entering the shell. It is understandable that the heat sink does not set a seal in the area where the water guide assembly drains, but sets a seal in other areas, so as to ensure smooth drainage of the heat sink.

[0028] In some technical solutions, optionally, the heat sink is arranged inside the housing at an angle relative to a horizontal plane.

[0029] In this technical solution, the heat sink can be arranged inside the shell at an angle relative to the horizontal plane, so that one side of the drainage part is arranged close to the drainage hole, and the other side is arranged away from the drainage hole, and the height of the drainage part close to the drainage hole is lower than the height of the side away from the drainage hole. In this way, water can be drained more quickly to the area of ​​the water guide component close to the drainage hole through the drainage part, thereby increasing the drainage speed.

[0030] In some technical solutions, optionally, the inclination angle of the heat sink relative to the horizontal plane is greater than or equal to 0.2° and less than or equal to 3°.

[0031] In some technical solutions, optionally, the inclination angle of the heat sink is 0.5°.

[0032] In some technical solutions, optionally, the inclination angle of the heat sink is 0.8°.

[0033] In some technical solutions, optionally, the inclination angle of the heat sink is 1°.

[0034] In some technical solutions, optionally, the water guiding component is obliquely arranged on the inner wall of the shell, and the height of the water guiding component close to the drainage hole is lower than the height of the side away from the drainage hole.

[0035] In this technical solution, in order to further improve the drainage efficiency, the water guide component can be tilted on the inner wall of the shell so that the height of the water guide component close to the drainage hole is lower than the height of the side away from the drainage hole.

[0036] The second aspect of the utility model proposes a mobile energy storage device, including the waterproof chassis for mobile energy storage device in any technical solution of the first aspect; an inverter, located in the waterproof chassis for mobile energy storage device, and located on the side of the heat sink away from the top of the shell; a battery module, located in the waterproof chassis for mobile energy storage device, and located on the side of the heat sink away from the top of the shell.

[0037] According to the mobile energy storage device provided by the utility model, it includes a waterproof chassis for mobile energy storage equipment, an inverter and a battery module in any technical solution of the first aspect. The inverter is arranged on a side of the heat sink away from the top of the shell. That is, the inverter is located in the waterproof chassis for mobile energy storage equipment and is located below the heat sink. The battery module is arranged on a side of the heat sink away from the top of the shell. That is, the battery module is located in the waterproof chassis for mobile energy storage equipment and is located below the heat sink. Such an arrangement can not only use the heat sink to dissipate heat for the inverter and the battery module, but also because the inverter and the battery module are arranged below the heat sink, the heat sink can be used for water diversion to ensure that rainwater does not corrode the inverter and the battery module. Since the mobile energy storage device includes the waterproof chassis for mobile energy storage equipment in any technical solution of the first aspect, the mobile energy storage device has all the beneficial technical effects of the waterproof chassis for mobile energy storage equipment in any technical solution of the first aspect.

[0038] In some technical solutions, optionally, the mobile energy storage device includes a balcony photovoltaic energy storage device. The balcony photovoltaic energy storage device can be charged through photovoltaic panel photoelectric conversion and / or city electricity, and the balcony photovoltaic energy storage device can provide power to electrical equipment. The balcony photovoltaic energy storage device is relatively small and easy to carry and move. Users can move the location according to their power needs, for example, from the balcony to the garage or even outdoors.

DETAILED DESCRIPTION

[0055] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0056] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0057] Refer to the following Figures 1 to 12 The invention describes a waterproof case for a mobile energy storage device and a mobile energy storage device according to some embodiments of the invention.

[0058] According to an embodiment of the first aspect of the present utility model, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig.11 As shown, a waterproof case 10 for a mobile energy storage device is proposed, comprising a housing 1, a drainage hole 2, a water guide assembly 3 and a heat sink 4. The drainage hole 2 is arranged on the side wall of the housing 1; the water guide assembly 3 is arranged on the inner side wall of the housing 1 and communicated with the drainage hole 2; the heat sink 4 is arranged inside the housing 1 and located between the top of the housing 1 and the water guide assembly 3. The heat sink 4 is used for heat dissipation and is configured to guide water into the water guide assembly 3.

[0059] The utility model provides a waterproof chassis 10 for a mobile energy storage device, comprising a shell 1, a drain hole 2, a water guide component 3 and a heat sink 4. The heat sink 4 is capable of dissipating heat, and the heat sink 4 is also constructed as a structure capable of guiding water into the water guide component 3. The drain hole 2 is arranged on the side wall of the shell 1, and the water guide component 3 is arranged on the inner wall of the shell 1 and is connected to the drain hole 2, so that the water can be drained to the drain hole 2 through the water guide component 3. The heat sink 4 is arranged in the shell 1 and is located between the top of the shell 1 and the water guide component 3, so that the water can be drained into the water guide component 3 through the heat sink 4, and then the drainage function is realized through the water guide component 3. By arranging the heat sink 4 between the top of the shell 1 and the water guide component 3, not only can the heat sink 4 be used for drainage, but also because the heat sink 4 is arranged close to the top and can be in contact with water, it is also beneficial to improve the heat dissipation effect of the heat sink 4. Specifically, when the heat sink 4 is used for heat dissipation, the circuit components and parts that need heat dissipation inside the housing 1 can be arranged on the side of the heat sink 4 away from the top of the housing 1, so that heat dissipation can be achieved and rainwater can be prevented from corroding the circuit components and parts that need heat dissipation. It is understandable that some devices in the related art must have heat dissipation holes 61 on the top, so when it rains, rainwater will enter the interior of the device through the heat dissipation holes 61, causing the device to short-circuit or be damaged. Therefore, the present application sets a water guide component 3 on the side wall inside the housing 1 and uses the heat sink 4 for drainage, so that the rainwater entering the interior of the device can be guided and discharged, thereby avoiding the problem of rainwater affecting the device.

[0060] Among them, combined Figure 6 and Fig. 9 As shown, it shows that when rain drops on the heat sink 4 ( Figure 6 The arrow in the middle indicates the direction of rainwater dripping), and the flow direction on the heat sink 4 ( Fig. 9 Two types of arrows are used to indicate the direction of water flow), from Fig. 9 It can be seen that the water dripping on the heat sink 4 will flow in all directions and then gather in the water guide component 3, or it can also flow along the inner wall of the shell 1 to the drain hole 2 and finally be discharged through the drain hole 2.

[0061] In some embodiments, the water guide component 3 may be optionally arranged relative to the heat dissipation hole 61 arranged on the top of the housing 1. In this way, the water guide component 3 can be arranged in a targeted manner to improve the drainage effect of the water guide component 3.

[0062] In some embodiments, optionally, the drainage hole 2 includes a plurality of drainage holes 2, and the plurality of drainage holes 2 are arranged in a preset regular pattern, or the plurality of drainage holes 2 are arranged irregularly.

[0063] In some embodiments, optionally, the heat sink 4 includes: a plurality of heat sink fins 42 , any two adjacent heat sink fins 42 form a drainage portion 41 , and the drainage portion 41 is used to guide water into the water guide component 3 .

[0064] In this embodiment, the heat dissipation effect of the heat sink 4 can be improved by providing the heat dissipation fins 42, and the drainage portion 41 is formed by the heat dissipation fins 42 for drainage, thereby further improving the heat dissipation effect of the heat sink 4. It can be understood that when water flows in the drainage portion 41, it will take away part of the heat of the heat sink 4, thereby improving the heat dissipation effect of the heat sink 4.

[0065] In some embodiments, optionally, the drainage portion 41 may be in the form of a drainage groove 411 , and the drainage groove 411 may be formed by the heat dissipation fins 42 of the heat dissipation element 4 .

[0066] In some embodiments, optionally, the water guide assembly 3 includes: a flow guide member 31, which is arranged on the inner wall of the shell 1; a flow baffle member 32, which is arranged on the flow guide member 31 or on the heat sink 4; and a water guide groove, which is formed by the flow guide member 31, the flow baffle member 32 and the inner wall of the shell 1, and is connected to the drainage hole 2.

[0067] In this embodiment, the water guide assembly 3 includes a flow guide 31, a flow baffle 32 and a water guide groove. The flow baffle 32, the flow guide 31 and the inner side wall of the housing 1 together form a water guide groove, so that water can be guided to the drain hole 2 through the water guide groove for discharge. Specifically, the flow baffle 32 can be arranged on the flow guide 31, or on the heat sink 4 arranged between the water guide assembly 3 and the top of the housing 1, so that the flow guide 31 and the flow baffle 32 can form a water guide groove with the inner side wall of the housing 1, and water can be discharged from the drain hole 2 through the water guide groove.

[0068] In some embodiments, the guide member 31 includes ribs formed on the inner wall of the shell 1 .

[0069] In some embodiments, optionally, the waterproof case 10 for the mobile energy storage device further includes: a mounting groove 43 disposed on the heat sink 4 , and the baffle 32 is disposed in the mounting groove 43 .

[0070] In this embodiment, the waterproof case 10 for a mobile energy storage device further includes a mounting groove 43. The mounting groove 43 is provided on the heat sink 4, so that the baffle 32 can be provided in the mounting groove 43. Specifically, the mounting groove 43 is provided on a side of the heat sink 4 close to the water guide assembly 3, so that when the baffle 32 is provided in the mounting groove 43, a water guide groove can be formed by the baffle 32 and the guide 31 and the inner side wall of the housing 1.

[0071] In some embodiments, the flow blocking member 32 is optionally an elastic flow blocking member or a non-elastic flow blocking member.

[0072] In this embodiment, the baffle 32 is an elastic baffle or a non-elastic baffle. The elastic baffle has elasticity, so the sealing of the water guide groove formed by the elastic baffle is good, and the size of the formed water guide groove can also be adjusted, which improves the user's use requirements. The non-elastic baffle has a long service life and is relatively stable, so it can improve the water guiding effect of the water guide groove.

[0073] In some embodiments, optionally, the water guiding component 3 includes an annular water guiding component, and the annular water guiding component is arranged along the circumferential direction of the inner wall of the shell 1.

[0074] In this embodiment, the water guide component 3 includes an annular water guide component, which is arranged along the circumferential direction of the inner wall of the housing 1. It can be understood that the annular water guide component is similar to a hollow component in the shape of a flange, so that when the annular water guide component is arranged along the circumferential direction of the inner wall of the housing 1, the middle part can flow out, so that other parts such as circuit components can be arranged in this part of the space, and a certain space is reserved for the arrangement of other parts.

[0075] In some embodiments, optionally, the heat sink 4 is disposed on the annular water guiding assembly, and a gap is provided between the heat sink 4 and the inner wall of the housing 1 .

[0076] In this embodiment, the heat sink 4 can be arranged on the annular water guide assembly, which facilitates the installation and fixation of the heat sink 4. At the same time, in order to further fix the heat sink 4, a certain gap can be reserved between the heat sink 4 and the inner side wall of the housing 1, thereby facilitating the adjustment of the heat sink 4 and improving the installation efficiency of the heat sink 4.

[0077] In some embodiments, optionally, the heat sink 4 is fixedly mounted on the annular water guide assembly by bolts.

[0078] In some embodiments, optionally, Fig.10 As shown, the waterproof case 10 for the mobile energy storage device further includes: a sealing member 5, which is arranged in a partial area of ​​the gap.

[0079] In this embodiment, when a gap is left between the heat sink 4 and the inner wall of the housing 1, it is convenient to install the heat sink 4, but some water will flow into the interior of the housing 1 through the gap, so by setting a seal 5 to seal part of the gap, it is possible to prevent water from entering the interior of the housing 1. It can be understood that the heat sink 4 is not provided with a seal 5 in the area where the drainage portion 41 of the water guide assembly 3 is divided, and the seal 5 is provided in other areas, so as to ensure smooth drainage of the heat sink 4.

[0080] In some embodiments, optionally, the seal 5 comprises a rubber seal.

[0081] In some embodiments, optionally, the sealing member 5 is formed by applying sealing glue.

[0082] In some embodiments, optionally, the seal 5 comprises a rubber sealing strip.

[0083] In this embodiment, when the sealing member 5 is a rubber sealing strip, the sealing strip can not only achieve sealing to ensure that the heat sink 4 can drain water into the water guide component 3, but also the water can flow along the rubber sealing strip. When it flows to the end of the sealing strip, the water can be drained into the water guide component 3, thereby achieving further drainage.

[0084] In some embodiments, optionally, the heat sink 4 is disposed inside the housing 1 at an angle relative to a horizontal plane.

[0085] In this embodiment, the heat sink 4 can be arranged inside the shell 1 at an angle relative to the horizontal plane, so that one side of the drainage portion 41 is arranged close to the drainage hole 2, and the other side is arranged away from the drainage hole 2, and the height of the drainage portion 41 close to the drainage hole 2 is lower than the height of the side away from the drainage hole 2. In this way, water can be more quickly drained to the area of ​​the water guide component 3 close to the drainage hole 2 through the drainage portion 41, thereby increasing the drainage speed.

[0086] In some embodiments, optionally, the inclination angle of the heat sink 4 relative to the horizontal plane is greater than or equal to 0.2° and less than or equal to 3°.

[0087] In some embodiments, optionally, Figure 8 As shown, the inclination angle of the heat sink 4 is 0.5°.

[0088] In some embodiments, optionally, the inclination angle of the heat sink 4 is 0.8°.

[0089] In some embodiments, optionally, the inclination angle of the heat sink 4 is 1°.

[0090] In some embodiments, optionally, the water guiding component 3 is obliquely disposed on the inner wall of the shell 1 , and the height of the water guiding component 3 close to the drainage hole 2 is lower than the height of the water guiding component 3 away from the drainage hole 2 .

[0091] In this embodiment, in order to further improve the drainage efficiency, the water guide component 3 can be tilted on the inner wall of the shell 1 so that the height of the water guide component 3 close to the drainage hole 2 is lower than the height of the side away from the drainage hole 2.

[0092] In some embodiments, optionally, the waterproof case 10 for the mobile energy storage device further includes: a top cover 6 disposed on the housing 1 , and a heat dissipation hole 61 is disposed on the top cover 6 .

[0093] In this embodiment, a top cover 6 may be provided on the housing 1, so that the components inside the housing 1 can be protected by the top cover 6. At the same time, heat dissipation holes 61 are provided on the top cover 6 to improve the heat dissipation effect.

[0094] like Fig.12 As shown, the second aspect of the utility model proposes a mobile energy storage device 100, including the waterproof case 10 for mobile energy storage equipment in any one embodiment of the first aspect; the inverter 20 is located in the waterproof case 10 for mobile energy storage equipment, and is located on the side of the heat sink 4 away from the top of the shell; the battery module 30 is located in the waterproof case 10 for mobile energy storage equipment, and is located on the side of the heat sink 4 away from the top of the shell.

[0095] According to the mobile energy storage device 100 provided by the utility model, it includes the waterproof case 10 for mobile energy storage equipment, the inverter 20 and the battery module 30 in any one embodiment of the first aspect. The inverter 20 is located in the waterproof case 10 for mobile energy storage equipment and is located below the heat sink 4, that is, the inverter 20 is arranged on the side of the heat sink 4 away from the top of the shell 1. The battery module 30 is located in the waterproof case 10 for mobile energy storage equipment and is located below the heat sink 4, that is, the battery module 30 is arranged on the side of the heat sink 4 away from the top of the shell 1. Such an arrangement can not only utilize the heat sink 4 to dissipate heat for the inverter 20 and the battery module 30, but also because the inverter 20 and the battery module 30 are arranged below the heat sink 4, the heat sink 4 can be used to block water and drain water, ensuring that rainwater does not corrode the inverter 20 and the battery module 30. Since the mobile energy storage device 100 includes the waterproof case 10 for mobile energy storage devices in any one of the embodiments of the first aspect, the mobile energy storage device 100 has all the beneficial technical effects of the waterproof case 10 for mobile energy storage devices in any one of the embodiments of the first aspect.

[0096] In some embodiments, the mobile energy storage device 100 may optionally include a balcony photovoltaic energy storage device. The balcony photovoltaic energy storage device may be charged through photovoltaic panel photoelectric conversion and / or city electricity, and the balcony photovoltaic energy storage device may provide power to electrical equipment. The balcony photovoltaic energy storage device is relatively small and easy to carry and move, and users may relocate the device according to their power needs, for example, from the balcony to the garage or even outdoors.

[0097] It is understandable that the reason why the present application sets a large-area heat sink 4 at the top is that:

[0098] The existing balcony photovoltaic energy storage device mainly includes a battery module 30, but does not include an inverter 20. The existing balcony photovoltaic energy storage device and the inverter 20 are separately set up independently, so the heat generated by the inverter 20 will not affect the battery module 30. Based on this, the existing balcony photovoltaic energy storage device does not require a large heat dissipation area to meet the heat dissipation requirements, and its heat dissipation member 4 is set around the balcony photovoltaic energy storage device to meet the heat dissipation requirements. However, the solution of the separate setting of the battery module 30 and the inverter 20 has disadvantages, such as complex wiring (the user needs to make additional wiring between the inverter 20 and the battery module 30) and a large installation area. Therefore, the present application provides an energy storage device with an integrated design of a battery module 30 and an inverter 20, that is, the inverter 20 and the battery module 30 are both set in the same chassis. For the user, there is no need to reconnect the wiring between the inverter 20 and the energy storage device, which simplifies the overall structure, and its occupied area is relatively small. However, since the battery module 30 and the inverter 20 are integrated, the heat generated by the inverter 20 is very high. Therefore, the integrated design of the inverter 20 and the battery module 30 has relatively high requirements for heat dissipation and requires a larger heat dissipation area. Therefore, the present application configures the entire top area as the heat sink 4, that is, the present application configures the heat sink 4 as follows: the side wall of the heat sink 4 is basically in contact with the inner wall of the shell, and only a gap is reserved for the installation of the heat sink 4, so that the area of ​​the heat sink 4 and the heat dissipation effect are maximized to improve the heat dissipation performance. However, in order to prevent rainwater from penetrating into the chassis through the heat sink 4 on the top and damaging the inverter 20 and the battery module 30, the present application provides a waterproof chassis for a mobile energy storage device.
