[0039] The publication of this application provides many different embodiments or examples to realize different structures of the application. To simplify the publication of this application, the configuration and installation in a particular embodiment are described below. Of course, these are merely examples and are not intended to be limiting to the application. In addition, the application allows for the repetition of reference figures and / or reference letters in different embodiments, and these reference figures and / or reference letters are for simplification and clarification purposes and do not themselves imply relationships between the various embodiments and / or installations discussed.

[0040] The embodiments of this application are described in detail below, and examples of these embodiments are illustrated. Throughout this description, any identical or similar designations represent identical or similar components or parts having identical or similar functions. The embodiments described below with reference to the drawings are illustrative and are used solely for interpreting this application and should not be understood as limiting it.

[0041] As shown in Figure 1-4, the present invention discloses an energy storage power supply 100. The energy storage power supply 100 comprises a housing 10, a battery module 20, an inverter 30, and a blower 40. The housing 10 has a mounting cavity 11, and a heat dissipation structure 12 is formed in the housing 10. The battery module 20 is mounted inside the mounting cavity 11. The inverter 30 is mounted inside the mounting cavity 11 and is thermally coupled to the heat dissipation structure 12, and is also electrically connected to the battery module 20. The blower 40 is mounted on the outside of the housing 10, and the flowing air generated by the blower 40 blows through the heat dissipation structure 12.

[0042] What can be understood is that, because the battery module 20 has a large thermal capacity and relatively low heat generation, it can be cooled by natural heat dissipation. However, because the inverter 30 generates a large amount of heat, it is necessary to cool it using the heat dissipation structure 12 formed on the housing 10 in combination with the blower 40. As the heat generated during the operation of the inverter 30 is conducted onto the heat dissipation structure 12, the heat is dissipated to the outside via the blower 40, thereby lowering the temperature of the inverter 30 and ensuring the cooling effect of the energy storage power supply.

[0043] In other words, the energy storage power supply 100 according to the present invention utilizes the casing 10 as a support and also as a heat dissipator, eliminating the need to add or install a heat dissipator. This reduces the overall height and volume of the energy storage power supply 100 and achieves high protection for the inverter 30.

[0044] The housing 10 of this invention may be made of a metal material, and an energy storage power supply 100 manufactured in this manner will be more robust and durable.

[0045] Through thermal coupling between the inverter 30 and the heat dissipation structure 12, the inverter 30 becomes connected to the heat dissipation structure 12 either through direct heat conduction or through indirect heat conduction via an intermediary connecting member.

[0046] The electrical connection between the inverter 30 and the battery module 20 can be either a direct or indirect connection. For example, the battery module 20 may be indirectly connected to the inverter 30 via a battery protection board. The battery protection board can provide protection against overvoltage, overtemperature, overcurrent, etc., and can also interrupt the electrical connection between the battery and the outside.

[0047] As described above, by forming a heat dissipation structure 12 in the housing 10 of the energy storage power supply 100 according to the present invention, and by thermally coupling the inverter 30 with the heat dissipation structure 12, and by attaching a blower 40 to the outside of the housing 10, and by the technical means that the flowing air generated by the blower 40 blows through the heat dissipation structure 12, the present invention provides a superior heat dissipation effect of the inverter 30 compared to natural heat dissipation methods, and also reduces the weight of the inverter 30. The introduction of the blower 40 improves heat dissipation efficiency, and in addition, the housing 10 performs both heat dissipation and support functions, saving internal space and manufacturing costs of the energy storage power supply 100.

[0048] As shown in Figure 4, in some implementations, the heat dissipation structure 12 has a plurality of heat dissipation fins 121, and the plurality of heat dissipation fins 121 are installed on the bottom 101, side 102 and / or top 103 of the housing 10.

[0049] Specifically, the installation of multiple heat dissipation fins 121 on the bottom 101, side 102 and / or top 103 of the housing 10 includes the following configurations: 1. Multiple heat dissipation fins 121 are installed at one of the following locations on the bottom 101, side 102 and top 103 of the housing 10. 2. Multiple heat dissipation fins 121 are installed at two of the following locations on the bottom 101, side 102 and top 103 of the housing 10. 3. Multiple heat dissipation fins 121 are all installed on the bottom 101, side 102 and top 103 of the housing 10.

[0050] As shown in Figure 4, when multiple heat dissipation fins 121 are installed on the bottom 101 of the housing 10 of the energy storage power supply 100, the entire energy storage power supply 100 looks more aesthetically pleasing. In addition, because multiple heat dissipation fins 121 are installed on the bottom 101 of the housing 10 of the energy storage power supply 100, it is not easy for a user to touch the heat dissipation fins 121 and cause burns when lifting the energy storage power supply 100.

[0051] In addition, installing multiple heat dissipation fins 121 on the bottom 101 of the housing 10 of the energy storage power supply 100 also serves to prevent rainwater from entering the mounting cavity 11, resulting in a superior waterproofing effect. This prevents the circuit board 31 inside the inverter 30 from short-circuiting and breaking when moisture from the air enters the mounting cavity 11 during rainy or humid weather when the energy storage power supply 100 is used in an outdoor environment.

[0052] When multiple heat dissipation fins 121 are installed on the side 102 or top 103 of the housing 10 of the energy storage power supply 100, the electronic components in the mounting cavity 11 can dissipate heat from the side 102 and top 103 of the housing 10, allowing for greater diversification of heat dissipation methods and heat dissipation paths.

[0053] In some configurations, multiple heat dissipation fins 121 are arranged radially, and a mounting space 1201 is formed in the middle, and the blower 40 is mounted within the mounting space 1201.

[0054] Specifically, as shown in Figure 4, a first fastening member 41 may be installed on the blower 40, and a second fastening member 1211 that fits the first fastening member 41 may be installed on the heat dissipation fin 121. The first fastening member 41 fastens with the second fastening member 1211, thereby attaching the blower 40 to the center of the heat dissipation fin 121. There are no restrictions on whether the first fastening member 41 is a fastening column and the second fastening member 1211 is a fastening hole, or whether the first fastening member 41 is a fastening hole and the second fastening member 1211 is a fastening column.

[0055] The blower 40 is mounted on the outside of the housing 10, and the flowing air generated by the blower 40 blows through the heat dissipation structure 12, forming a heat dissipation path, thereby achieving a heat dissipation effect on the inverter 30 inside the mounting cavity 11. In other words, since one end of the multiple heat dissipation fins 121 surrounds the mounting space 1201, the blower 40 is mounted within the mounting space 1201, and as the blower 40 rotates, the heat dissipation airflow comes into contact with the heat dissipation fins 121 from all directions, which helps to enhance the heat dissipation effect on the heat dissipation fins 121.

[0056] Regardless of whether the multiple heat dissipation fins 121 are installed on the bottom 101, side 102, or top 103 of the housing 10, the blower 40 may be installed in the outer center of the housing 10, and the heat dissipation fins 121 may be arranged at intervals around the blower 40, thereby forming a shorter, more direct heat dissipation path, creating a larger heat dissipation area, and achieving a better heat dissipation effect.

[0057] As shown in Figure 5, in some implementations, the arrangement density of the heat dissipation fins 121 gradually changes from dense to sparse from the center to the outer periphery, and the arrangement height of the heat dissipation fins 121 gradually changes from low to high from the center to the outer periphery.

[0058] Specifically, when viewed from the middle internal area of ​​the heat dissipation fins 121, this area is close to the heat source and has a large heat output, so the heat dissipation fins 121 are designed to be densely packed. By arranging the heat dissipation fins 121 densely in this way, the heat dissipation area within the finite space is increased, thereby allowing heat to be absorbed and conducted more efficiently. Despite the high density of the heat dissipation fins 121, if the height of the heat dissipation fins 121 is relatively low, on the one hand, it ensures that the heat dissipation fins 121 are rationally arranged within the finite space, thereby preventing the heat dissipation fins 121 from being too high and occupying excessive space, thus not affecting the mounting and arrangement of other components. On the other hand, if the height of the heat dissipation fins 121 is relatively low, it helps to conduct heat to the outside more quickly, prevents heat from accumulating in the central internal area of ​​the heat dissipation fins 121, and is advantageous for heat to diffuse to the surrounding area outside the housing 10, resulting in a better heat dissipation effect.

[0059] In the central internal area and the area outside the heat dissipation fins 121 relative to them, the height of the heat dissipation fins 121 is greater. This is because the external space of the heat dissipation fins 121 is relatively wider, allowing the higher heat dissipation fins 121 to exchange heat better with the surrounding air, thereby increasing heat dissipation efficiency. In addition, the external heat dissipation fins 121 are relatively sparser, which reduces the overall weight of the heat dissipator while ensuring the heat dissipation effect. Sparsely arranging the heat dissipation fins 121 reduces the amount of material used, lowering costs, and also makes the heat dissipator lighter, easier to install and carry.

[0060] The angular range in which the inner and outer heat dissipation fins 121 gradually change from dense to sparse is (10°, 15°).

[0061] The energy storage power supply 100 according to this invention effectively enhances the uniform heat distribution effect through a design in which the heat dissipation fins 121 are densely packed and low on the inside and high and sparse on the outside. Heat generated from heat sources such as the inverter 30 is first rapidly absorbed and conducted to the densely packed heat dissipation fins 121 located in the central internal area of ​​the housing 10, and then gradually dissipated to the outside. Because the heat dissipation fins 121 in the outer area are high and sparse, better heat exchange with the air becomes possible, thereby uniformly dissipating heat to the surrounding environment and avoiding localized overheating.

[0062] In addition, the design of the heat dissipation fins 121, which are densely packed and low on the inside and high and sparse on the outside, ensures heat dissipation performance while also achieving the goal of weight reduction, which contributes to the overall lightweight design of the inverter for a portable power supply with high protection.

[0063] In some implementations, the blower 40 is either a centrifugal blower or an axial flow blower.

[0064] Specifically, when an axial flow fan is in operation, the blades blow air in the same direction as the axis; in other words, the inlet direction is parallel to the outlet direction. Axial flow fans can typically provide a large airflow, helping to quickly remove heat from within the energy storage power supply 100 and achieve effective heat dissipation. Axial flow fans have a relatively simple structure and low manufacturing costs, making them highly cost-effective in use. Axial flow fans are applicable to heat dissipation in most energy storage power supplies and are particularly suitable for situations where rapid heat dissipation with a large airflow is required.

[0065] When a centrifugal fan operates, the blades blow air perpendicular to the axis (i.e., radially), meaning the inlet direction is perpendicular to the outlet direction. This allows centrifugal fans to generate high air pressure, which helps dissipate heat from within energy storage devices, particularly in situations where the heat dissipation path is long or heat dissipation resistance is high. By altering the flow direction within the cavity, centrifugal fans can expel air axially perpendicular to the axis, which is highly beneficial for certain heat dissipation designs. The fact that centrifugal fans typically produce less noise than axial fans under the same conditions of size and other comparable performance conditions helps improve the overall user experience of energy storage devices. Centrifugal fans are suitable for situations where airflow needs to be rotated 90 degrees for exhaust or where high air pressure is required for heat dissipation.

[0066] If the blower 40 is a centrifugal blower, the blowing direction of the centrifugal blower is perpendicular to the blowing direction, making it possible for the centrifugal blower to achieve effective airflow in a smaller space. This means that in the design of the energy storage power supply 100, the position and direction of the centrifugal blower can be positioned more flexibly to adapt to the internal space arrangement of the energy storage power supply 100. Therefore, by optimizing the arrangement and direction of the blowers, it is possible to utilize the finite space within the energy storage power supply more effectively. For example, by mounting the centrifugal blower on the side or top of the power supply unit, it is possible to avoid occupying excessive space at the front, back, or bottom of the energy storage power supply 100. This arrangement not only reduces the overall volume of the energy storage power supply 100 but also helps to lower its height, making the structure of the energy storage power supply 100 more compact and portable.

[0067] In other words, the characteristic of the centrifugal blower, where the blowing direction is perpendicular to the blowing direction, allows for more flexible use of space in the design of the energy storage power supply 100, thereby effectively reducing the overall volume and height of the energy storage power supply 100. This design not only improves the structural compactness and portability of the energy storage power supply 100, but also helps to increase the heat dissipation efficiency of the energy storage power supply 100 and extend its service life.

[0068] In addition, the blower 40 achieves an IP68 protection rating by vacuum plating the printed circuit board assembly inside the blower 40 through a resin injection method, giving the blower 40 extremely high dustproof and waterproof performance, making it adaptable to various harsh working environments and ensuring normal heat dissipation and operation of the energy storage power supply 100.

[0069] As shown in Figure 5, in some implementations, the heat dissipation structure 12 further has a protrusion 122, which is located within the mounting cavity 11 and fixed to the housing 10, and the protrusion 122 is thermally coupled to the power elements of the inverter 30.

[0070] What we can understand is that when two solid surfaces come into contact, factors such as surface roughness and gaps create an obstruction to heat conduction between the two solids, and this obstruction is called contact thermal resistance.

[0071] Because the contact area between the protrusion 122 and the power element 311 of the inverter 30 is relatively large, and the design of the protrusion 122 may help to reduce gaps and air, it is possible to reduce the contact thermal resistance between the inverter 30 and the housing 10. This means that the obstruction to heat conduction between the inverter 30 and the housing 10 is reduced, thereby improving the heat dissipation efficiency of the power element 311 of the inverter 30.

[0072] More specifically, referring to Figure 3, the power elements 311 of the inverter 30 include elements such as a transformer 3111 and an inductor 3112. The power elements 311, such as the transformer 3111 and the inductor 3112, are mounted as close as possible to the protrusion 122 on the housing 10. This serves to minimize the contact thermal resistance between the inverter 30 and the housing 10 using the protrusion 122.

[0073] Therefore, the present invention aims to reduce the contact thermal resistance between the inverter 30 and the housing 10 by allowing the protrusion 122 installed at the bottom of the mounting cavity 11 to make thermal coupling contact with the power element 311 of the inverter 30, thereby increasing the heat dissipation efficiency of the inverter 30 to the power element 311.

[0074] As shown in Figure 6, in some implementations, a thermal conductive layer 123 is installed between the protrusion 122 and the power element 311, and the protrusion 122 is thermally coupled to the power element 311 of the inverter 30 via the thermal conductive layer 123.

[0075] Specifically, the thermal conductive layer 123 may be a thermal conductive structure made of thermal conductive layer material, thermal conductive gel, or other high thermal conductive material. There are no limitations to this.

[0076] Thus, the energy storage power supply 100 according to the present invention has a heat conductive layer between the protrusion 122 on the inside of the housing 10 and the power element 311, and the heat conductive layer is made of a flexible material, so that the power element 311 of the inverter 30 is in close contact with the protrusion 122, and the heat conduction between the inverter 30 and the protrusion 122 is accelerated, thereby promoting the conduction and dissipation of heat from the inverter 30 onto the housing 10.

[0077] In some implementations, the thermal conductive layer 123 is less than 1 mm thick, and the thermal conductivity of the thermal conductive layer 123 is greater than 3 W / M / K.

[0078] What can be understood is that the heat conduction layer 123 is too thick, which may reduce the heat conduction efficiency between the inverter 30 and the protrusion 122.

[0079] Therefore, by setting the thickness of the heat conduction layer 123 of the present invention to less than 1 mm and setting the thermal conductivity of the heat conduction layer 123 to 3 W / M / K or higher, the heat conduction efficiency between the inverter 30 and the protrusion 122 is ensured, thereby ensuring that the heat from power elements such as the circuit board of the inverter 30 is quickly conducted to the housing 10.

[0080] In other words, in this invention, a protrusion 122 is installed on the inside of the housing 10 within the mounting cavity 11, making it possible to reduce the thickness of the heat conduction layer 123, thereby optimizing the heat conduction efficiency between the inverter 30 and the housing 10.

[0081] As shown in Figure 1, in some implementations, the energy storage power supply 100 is further equipped with a support pad 50, and the support pad 50 is located on the bottom 101 of the housing 10, and the support pad 50 is used to contact the external support surface, thereby separating the bottom 101 of the housing 10 from the external support surface.

[0082] Specifically, by installing a support pad 50 on the bottom 101 of the housing 10, on the one hand, the heat dissipation structure 12 is not visible from the outside of the energy storage power supply 100, resulting in a neat appearance, and on the other hand, the drive airflow between the blower 40 and the heat dissipation structure 12 can circulate within a relatively sufficient space, thereby ensuring the heat dissipation efficiency of the heat dissipation structure 12 on the housing 10.

[0083] In addition, the energy storage power supply 100 according to this invention is supported by the support pad 50, making it difficult for people to touch the blower 40, thereby improving the safety of using the energy storage power supply 100.

[0084] It is optional to install four support pads 50. The four support pads 50 are located at each of the four corners of the housing 10, thereby ensuring that the energy storage power supply 100 is stably supported by the external support surface. Of course, in other embodiments of the present invention, the number of support pads 50 can be adjusted according to actual needs and is not limited to four.

[0085] As shown in Figure 2, in some implementations, the energy storage power supply 100 further comprises a first cover plate 60, which is fixedly attached to the outside of the housing 10 and covers the blower 40, and the first cover plate 60 is provided with ventilation holes 61.

[0086] In other words, the installation position of the first cover plate 60 corresponds to the installation position of the blower 40. When the blower 40 is attached to the bottom 101 of the housing 10, the first cover plate 60 is also attached to the bottom 101 of the housing 10. When the blower 40 is attached to the side 102 of the housing 10, the first cover plate 60 is also attached to the side 102 of the housing 10. When the blower 40 is attached to the top 103 of the housing 10, the first cover plate 60 is also attached to the top 103 of the housing 10.

[0087] In this invention, the first cover plate 60 is fixed to the outside of the housing 10 and covers the blower 40 and the heat dissipation fins 121, thereby preventing the blower 40 and the heat dissipation fins 121 from being exposed and protecting the blower 40. It is also possible to prevent the user from touching the heat dissipation fins 121 and getting burned when lifting the energy storage power supply 100. In addition, the first cover plate 60 also has a certain aesthetic effect. The first cover plate 60 can be fixed and attached to the outside of the housing 10 using screws or other components, and there are no limitations thereto.

[0088] In this invention, ventilation holes 61 are provided in the first cover plate 60, and under the operation of the blower 40, the heat generated in the inverter 30 can be dissipated to the outside through the ventilation holes 61 on the first cover plate 60, thereby conducting the heat from the inverter 30 to the housing 10 and achieving heat dissipation.

[0089] In some implementations, the first cover plate 60 has a first bottom plate 62 and a first side plate 63 installed around the first bottom plate 62, forming an air passage between the heat dissipation structure 12 and the first cover plate 60, and the ventilation holes 61 have a first ventilation hole 611 and a second ventilation hole 612, with the ventilation holes 61 installed between the first ventilation hole 611 and the second ventilation hole 612, the first ventilation hole 611 installed in the first bottom plate 62 and the second ventilation hole 612 installed in the first side plate 63.

[0090] Specifically, the first cover plate 60 is provided with both a first ventilation hole 611 and a second ventilation hole 612. In other words, when ventilation holes in two directions are installed in the first cover plate 60, it becomes possible to form an independent air passage between the first cover plate 60 and the housing 10, thereby enabling heat to be dissipated more quickly to the energy storage power supply 100 according to the present invention.

[0091] As shown in Figure 4, multiple first ventilation holes 611 can be installed and arranged in a row. Multiple second ventilation holes 612 can also be installed and arranged in a row. It is understood that the more first ventilation holes 611 and second ventilation holes 612 there are, and the larger the diameter of the holes, the better the ventilation effect and the better the final heat dissipation effect.

[0092] Thus, the energy storage power supply 100 according to the present invention is capable of forming independent air passages between the first cover plate 60 and the housing 10 via the first ventilation holes 611 and the second ventilation holes 612 on the first cover plate 60, thereby improving the heat dissipation effect of the heat dissipation structure 12 of the housing 10.

[0093] In some implementations, the first ventilation opening 611 is the air intake and the second ventilation opening 612 is the air outlet. Alternatively, the second ventilation opening 612 is the air intake and the first ventilation opening 611 is the air outlet.

[0094] In other words, in this invention, the first ventilation hole 611 functions as either an inlet or an outlet, blowing cold outside air into the power supply when functioning as an inlet, or blowing out hot inside when functioning as an outlet. The second ventilation hole 612 also functions as either an inlet or an outlet, blowing cold outside air into the power supply when functioning as an inlet, or blowing out hot inside when functioning as an outlet. This depends on the heat dissipation requirements of the energy storage power supply 100 and the airflow paths within the energy storage power supply 100.

[0095] In this invention, the direction of the blower 40 is controlled to select whether to use the two ventilation holes as inlets or outlets.

[0096] Furthermore, it becomes possible to provide a grid in the first ventilation hole 611 or the second ventilation hole 612, which can serve to dissipate heat from the energy storage power supply 100 on the one hand, and to prevent foreign matter from entering the first cover plate 60 of the energy storage power supply 100 on the other hand.

[0097] In some implementations, the energy storage power supply 100 is further equipped with a support pad, which is installed on one side of the first cover plate 60 facing away from the blower 40, and is used to contact an external support surface, thereby separating the bottom of the first cover plate 60 from the external support surface.

[0098] In other words, in this invention, it is possible to directly install the support pad on the bottom of the first cover plate 60, which, on the one hand, makes the heat dissipation structure 12 invisible from the outside of the energy storage power supply 100, resulting in a neat appearance, and on the other hand, allows the drive airflow between the blower 40 and the heat dissipation structure 12 to circulate in a relatively spacious area, thereby ensuring the heat dissipation efficiency of the heat dissipation structure 12 on the housing 10.

[0099] Preferably, four support pads 50 are provided, each positioned at one of the four corners of the first cover plate 60, thereby ensuring the stability of the external support surface of the energy storage power supply 100. Of course, in other embodiments of the present invention, the number of support pads 50 can also be adjusted according to actual needs and is not limited to four.

[0100] As shown in Figures 2 and 4, in some implementations, the energy storage power supply 100 is further equipped with a support pad 50, and a through hole 64 corresponding to the support pad 50 is provided in the first bottom plate 62 of the first cover plate 60, and the support pad 50 is fixedly installed at the bottom of the first cover plate 60 together with the housing 10 through the through hole 64, and the support pad 50 is used to contact the external support surface, thereby separating the bottom of the first cover plate 60 from the external support surface.

[0101] For example, as shown in Figure 4, when a heat dissipation fin 121 is installed on the bottom of the housing 10, it becomes possible to install a first connecting column 1212 on the heat dissipation fin 121, and to install a first connecting hole corresponding to the first connecting column 1212 on the support pad 50. By aligning the support pad 50 with the first connecting column 1212 through the first connecting hole, the support pad 50 can be fixed to the bottom of the housing 10. This allows the pressure applied to the support pad 50 to be directly transmitted to the housing 10, without being borne by the first cover plate 60, thereby effectively preventing damage to the first cover plate 60.

[0102] To give another example, if a heat dissipation fin 121 is installed on the bottom of the housing 10, it becomes possible to install a second connection hole in the heat dissipation fin 121, and a second connection column 52 corresponding to the second connection hole is installed on the support pad 50. By aligning the support pad 50 with the second connection hole via the second connection column 52, the support pad 50 can be fixed to the bottom of the housing 10, thereby directly transmitting the pressure applied to the support pad 50 to the housing 10, and not having the first cover plate 60 bear the burden, effectively preventing damage to the first cover plate 60.

[0103] To give yet another example, a first fastening post corresponding to the through hole 64 can be installed in the support pad 50, and a second fastening post with a fastening hole corresponding to the first fastening post can be installed in the housing 10. When the first fastening post penetrates the through hole 64 and fastens with the second fastening post, the support pad 50 penetrates the first cover plate 60 and the housing 10 and is stably attached to them. This transmits the pressure applied to the support pad 50 directly to the housing 10, without burdening the first cover plate 60, and more effectively prevents damage to the first cover plate 60.

[0104] Similarly, it can be understood that by directly installing the support pad on the bottom of the first cover plate 60, on the one hand, the heat dissipation structure 12 is not visible from the outside of the energy storage power supply 100, resulting in a neat appearance, and on the other hand, the driving airflow between the blower 40 and the heat dissipation structure 12 can circulate in a relatively spacious area, thereby ensuring the heat dissipation efficiency of the heat dissipation structure 12 on the housing 10.

[0105] Preferably, four support pads 50 are provided, each positioned at one of the four corners of the first cover plate 60, thereby ensuring the stability of the external support surface of the energy storage power supply 100. Of course, in other embodiments of the present invention, the number of support pads 50 can also be adjusted according to actual needs and is not limited to four.

[0106] As shown in Figure 2, in some implementations, the housing 10 has a first housing 13 and a second housing 14, the first housing 13 and the second housing 14 fit together to form a mounting cavity 11, the inverter 30 is fixed to the first housing 13, a heat dissipation structure 12 is installed in the first housing 13, and the battery module 20 is fixed to the second housing 14.

[0107] Specifically, the first housing 13 is the lower housing, and the second housing 14 is the upper housing. It is possible to install the first fastening member 131 on the first housing 13, and it is possible to install the second fastening member 141, which fastens with the first fastening member 131, on the second housing 14. The first fastening member 131 is a hollow first fastening column as shown in Figure 3, and the second fastening member 141 is a solid second fastening column corresponding to the first fastening column as shown in Figure 2.

[0108] In this invention, both the first housing 13 and the second housing 14 can be molded by die casting, resulting in a simple structure and convenient manufacturing.

[0109] In this invention, the design of the housing 10 includes a joint structure formed by joining the first housing 13 with the second housing 14, which facilitates the assembly of the energy storage power supply 100.

[0110] What can be understood is that, regardless of whether the corresponding heat dissipation structure 12 on the enclosure 10 is a bonded structure or not, it is possible to design the enclosure 10 as a bonded structure, and there is no restriction on this.

[0111] As shown in Figure 4, in some implementations, the first housing 13 is made of aluminum alloy, the inside of the first housing 13 is thermally coupled with the inverter 30, and a heat dissipation structure 12 is formed on the outside of the first housing 13.

[0112] What can be understood is that the first housing 13 is made of aluminum alloy, and because aluminum alloy has good thermal conductivity, the heat dissipation performance of the first housing 13 made of aluminum alloy material is also excellent. Furthermore, if a heat dissipation structure 12 is formed on the outside of the first housing 13, the heat dissipation structure 12 is also made of aluminum alloy, so the heat dissipation performance of the heat dissipation structure 12 of this invention is also good.

[0113] In addition, because aluminum alloys have a low density and higher strength compared to existing metal materials such as steel and copper, the first housing 13 made of aluminum alloy has excellent strength and is resistant to breakage.

[0114] In some implementations, the first housing 13 is subjected to anodizing treatment.

[0115] Specifically, applying anodizing treatment to the first housing 13 improves the corrosion resistance of the first housing 13 and increases its surface thermal emissivity, thereby improving its thermal radiation capacity.

[0116] As shown in Figures 3 and 5, in some implementations, a housing cavity 132 is provided in the first housing 13, and the inverter 30 is fixedly installed inside the housing cavity 132.

[0117] Specifically, the inverter 30 can be fixed and installed within the housing cavity 132 using screws or bolts, or by any other method. No limitations are placed on this here.

[0118] Thus, in this invention, the inverter 30 can be fixedly mounted inside the housing cavity 132, thereby dissipating heat through the heat dissipation structure 12 formed on the outside of the first housing 13, and achieving a good heat dissipation effect.

[0119] As shown in Figures 1 and 2, in some implementations, a panel 142 is installed on the second housing 14, and a power output port 1421 is provided on the panel 142.

[0120] In other words, the energy storage power supply 100 according to the present invention can output power to the outside through a power output port 1421 provided on the panel 142 of the second housing 14.

[0121] In some implementation configurations, the first housing 13 and the second housing 14 are fitted together vertically, with the first housing 13 installed below the second housing 14.

[0122] In other words, this invention makes it possible to construct the housing 10 with two halves of the housing that are fitted together vertically, resulting in a simple structure and facilitating mass production of the housing 10.

[0123] In addition, since the heat dissipation structure 12 is installed on the outside of the first housing 13 and the first housing 13 is installed below the second housing 14, in the energy storage power supply 100 according to the present invention, the heat dissipation structure 12 is positioned below the housing 10, thereby making it difficult to accidentally come into contact with the heat dissipation structure 12 and protecting the heat dissipation structure 12 from damage.

[0124] In some implementations, a temperature sensor is attached to the heat dissipation structure 12 to detect its temperature, and the energy storage power supply 100 controls the starting / stopping or rotation speed of the blower 40 based on the temperature of the heat dissipation structure 12.

[0125] In other words, in the energy storage power supply 100 according to the present invention, by further installing a temperature sensor on the housing 10, the energy storage power supply 100 can automatically control the start of the blower 40 when it detects that the temperature of the heat dissipation structure 12 is above a first threshold using the temperature sensor. This prevents the temperature of the heat dissipation structure 12 from becoming too high and is convenient for quickly performing heat dissipation processing for the energy storage power supply 100.

[0126] When the temperature sensor detects that the temperature of the heat dissipation structure 12 is below the second threshold, the energy storage power supply 100 can automatically control the stopping of the blower 40, which is convenient for improving the heat dissipation efficiency of the blower 40 and saving energy consumption.

[0127] For example, the first threshold could be 38°, 39°, 40°, 43°, 45°, 48°, 50°, 51°, 55°, or 60°. No restrictions are placed on it here.

[0128] For example, the second threshold could be 28°, 29°, 29.5°, 30°, 31°, 34°, 35°, 36°, 37°, or 38°. No restrictions are placed on this here.

[0129] Thus, in this invention, by installing a temperature sensor in the heat dissipation structure 12 and quickly sensing the temperature of the heat dissipation structure 12, the energy storage power supply 100 can quickly control the start of the blower 40 to begin heat dissipation, and quickly control the stop of the blower 40 to stop heat dissipation.

[0130] As shown in Figure 7, in some implementations, the energy storage power supply 100 further comprises a semiconductor cooling element 124, the semiconductor cooling element 124 having a hot end and a cold end, the cold end being thermally coupled to the inverter 30 and the hot end being thermally coupled to the heat dissipation structure 12.

[0131] What can be understood is that the heat dissipation structure 12 can have a semiconductor cooling element 124, and the essence of semiconductor cooling technology lies in highly efficient cooling and heat pumping, using semiconductor materials as a refrigerant and generating a cooling effect through the action of electric current. This technology has advantages such as energy saving, low environmental impact, miniaturization, and good cooling effect, and is widely applied in various fields. The principle of semiconductor cooling technology is to achieve cooling through electric current conduction and the thermoelectric effect of semiconductor materials. When electric current flows through a semiconductor material, one side of the semiconductor material becomes hot and the other side becomes cold. This is because the carriers in the semiconductor material cause energy transfer under the action of a thermoelectric field. By utilizing this effect, it becomes possible to conduct heat from the cold side to the hot side, thereby achieving a cooling effect.

[0132] In this embodiment, the cold end of the semiconductor cooling element 124 is thermally conductively connected to the inverter 30, and the hot end is thermally conductively connected to the heat dissipation structure 12. By using the heat dissipation structure 12 and the blower 40 to move the air from the hot end of the semiconductor cooling element 124 to the outside, cooling of the cold end is achieved, the temperature of the inverter 30 is lowered, and thereby the cooling effect of the energy storage power supply 100 is ensured.

[0133] In addition, the semiconductor cooling element 124 can be precisely controlled in temperature, and the power consumption parameters of the semiconductor cooling element 124 can be adjusted according to the user's needs, thereby achieving intelligent temperature control for the housing 10 and improving the user experience.

[0134] As shown in Figure 7, the heat dissipation structure 12 also includes an insulating member 125 surrounding the semiconductor cooling element 124. It is understood that, because the semiconductor cooling element 124 performs cooling at one end while heating at the other during operation, the insulating member 125 is necessary to protect the performance of the semiconductor cooling element 124 from external influences, and the insulating member 125 needs to be made of an insulating material with low thermal conductivity and excellent compressive properties, such as pearl cotton or foamed cotton. Of course, in other embodiments of the present invention, the material of the insulating member 125 can be adjusted according to actual needs and is not limited to the above.

[0135] Preferably, the thickness of the heat insulating member 125 depends on the compression characteristics of the heat insulating material and is usually 1.5 to 2 times the thickness of the semiconductor cooling element 124. The heat insulating member 125 is filled between the inverter 30 and the heat dissipation structure 12, and under the action of a pressing force applied to the heat dissipation structure 12 from below, the heat insulating member 125 is compressed and filled to ensure good heat retention performance.

[0136] As shown in Figure 8, in some implementations, one side of the heat dissipation structure 12 facing the inverter 30 has a mounting groove 126, and the semiconductor cooling element 124 is mounted in the mounting groove 126.

[0137] It is understood that the heat dissipation structure 12 functions as a support member for the semiconductor cooling element 124 and the blower 40, thereby allowing the heat dissipation structure 12, the semiconductor cooling element 124, and the blower 40 to work together to dissipate heat, making assembly easier. By mounting the semiconductor cooling element 124 in the mounting groove 126, the contact area between the hot end of the semiconductor cooling element 124 and the heat dissipation structure 12 can be increased, thereby improving the heat dissipation effect of the heat dissipation structure on the hot end of the semiconductor cooling element 124.

[0138] Preferably, the size of the mounting groove 126 is made slightly larger than the size of the semiconductor cooling element 124, and the depth of the mounting groove 126 is set to 0.1 mm - 0.2 mm to position the semiconductor cooling element 124. Furthermore, thermal resistance is eliminated by applying a thermal conductive material to the contact area between the mounting groove 126 and the semiconductor cooling element 124. The thermal conductive material is usually a fluid thermal conductive material such as silicone grease.

[0139] As shown in Figure 4, in some implementations, the outer wall of the mounting cavity 11 has a heat dissipation opening 15, and the heat dissipation structure 12 is attached to the heat dissipation opening 15.

[0140] Specifically, it is possible to fix the heat dissipation structure 12 to the heat dissipation port 15 using screws or bolts.

[0141] Thus, in this invention, the heat dissipation structure 12 can be attached to the heat dissipation port 15 on the outer wall of the mounting cavity 11, which is convenient for dissipating heat to the inverter 30 through the heat dissipation port 15.

[0142] As shown in Figures 4 and 8, in some implementations, the heat dissipation structure 12 has a mounting portion 127 and a fixed protrusion 128 installed surrounding the mounting portion 127, the mounting portion 127 extends into the heat dissipation opening 15, the semiconductor cooling element 124 is attached to the mounting portion 127, and the fixed protrusion 128 is fixed to the outer wall of the mounting cavity 11 via a connecting member, thereby closing the heat dissipation opening 15 through the heat dissipation structure 12.

[0143] What can be understood is that when the heat dissipation structure 12 is attached to the outer wall of the mounting cavity using connecting members as an independent assembly, on the one hand, the heat dissipation structure 12 is not visible from the outside of the energy storage power supply 100, resulting in a neat appearance, and on the other hand, the cold end of the semiconductor cooling element 124 can be brought into close contact with the inverter 30, thereby improving the cooling effect of the inverter 30.

[0144] Preferably, as shown in Figure 9, a sealing member 129 is fitted into the mounting portion 127. The outer wall of the sealing member 129 abuts against the inner wall of the heat dissipation port 15 of the housing 10. This improves the sealing of the connection between the heat dissipation structure 12 and the housing 10, preventing external dirt or liquid from entering the energy storage power supply 100 and reducing the failure rate of the energy storage power supply 100.

[0145] Preferably, by making the heat dissipation structure 12 a die-cast part that is integrally molded, the heat dissipation fins 121, mounting portion 127, and fixing protrusion 128 can all be molded only once, making the manufacturing of the heat dissipation structure 12 convenient. In addition, the weight of the heat dissipation structure 12 is reduced, which is advantageous for the lightweight design of the energy storage power supply 100.

[0146] As shown in Figure 9, in some implementations, the energy storage power supply 100 further includes a heat dissipation support 32, the inverter 30 has a circuit board 31, power elements 311 are provided on the circuit board 31, the heat dissipation support 32 is attached to the housing 10, the heat dissipation support 32 fixes the circuit board 31 and thermally couples with the power elements 311, and the heat dissipation support 32 further thermally couples with the heat dissipation structure 12.

[0147] What can be understood is that by fixing the circuit board 31 to the heat dissipation support 32, it becomes possible to protect the power elements 311. The heat dissipation support 32 is thermally conductively connected to the circuit board 31, and the heat dissipation support 32 is thermally conductively connected to the heat dissipation structure 12. As a result, during actual operation, the heat generated in the power elements 311 on the circuit board 31 is conducted from the circuit board 31 to the heat dissipation support 32, and then dissipated to the outside by the heat dissipation structure 12 and the blower 40. This improves the cooling effect on the inverter 30 and ensures the heat dissipation effect of the energy storage power supply 100.

[0148] Preferably, heat dissipation fins 32121 are installed on the heat dissipation support 32. The heat dissipation fins 32121 installed on the heat dissipation support 32 can perform a heat dissipation role, and by combining the heat dissipation fins 32121 with the heat dissipation structure 12, a cooling effect on the inverter 30 can be ensured, and it is certain that the energy storage power supply 100 has an excellent heat dissipation function. In the embodiment of the present invention, the number and area of ​​the heat dissipation fins 32121 can be selected according to the actual demand, thereby ensuring a cooling effect while having a relatively small area, which is advantageous for the lightweight design of the energy storage power supply 100.

[0149] As shown in Figure 10, in some implementations, the heat dissipation support 32 has a base 321 and a second cover plate 322, the base 321 has a second bottom plate 3211 and two second side plates 3212, the two second side plates 3212 are connected to both ends of the second bottom plate 3211, a heat conduction pad 312 is provided between the second bottom plate 3211 and the power element 311, the second cover plate 322 is connected to the two second side plates 3212, and a position limiting member 3221 for restricting the battery module 322 is installed on the second cover plate 322.

[0150] As can be understood, as shown in Figure 9, the base 321 is a U-shaped plate, and a heat conduction pad 312 is installed between the second bottom plate 3211 and the circuit board 31. When heat dissipation fins 32121 are installed on the second side plate 3212, the heat generated during the operation of the power elements 311 on the circuit board 31 is quickly conducted to the heat dissipation support 32 via the heat conduction pad 312, and then quickly dissipated through the heat dissipation fins 32121, thereby ensuring the heat dissipation effect of the circuit board 31.

[0151] A position limiting member 3221 is installed on the second cover plate 322 to restrict the position of the battery module 20. The position limiting member 3221 prevents the inverter 30 from shaking relative to the battery module 20, and on the other hand, it provides positioning for mounting the inverter 30, thereby not only facilitating assembly but also improving the reliability of the energy storage power supply.

[0152] Preferably, as shown in Figure 10, a accommodating groove 32111 for accommodating the semiconductor cooling element 124 is provided in the second bottom plate 3211. By making the size of the accommodating groove 32111 slightly larger than the size of the semiconductor cooling element 124 and setting the depth of the accommodating groove 32111 to 0.1 mm-0.2 mm, the semiconductor cooling element 124 is positioned, and thermal resistance is eliminated by applying a thermal conductive material to the contact position between the accommodating groove 32111 and the semiconductor cooling element 124. The thermal conductive material is usually a fluid thermal conductive material such as silicone grease. This not only improves the positioning function for the semiconductor cooling element 124 but also demonstrates the heat dissipation effect of the semiconductor cooling element 124 on the heat dissipation support frame 32.

[0153] Preferably, as shown in Figure 10, the inverter 30 further includes an insulating plate 33. The insulating plate 33 is sandwiched between the second bottom plate 3211 and the circuit board 31, and the insulating plate 33 is provided with relief holes 351 corresponding to the heat conductive pads 312. It is understood that the additional insulating plate 33 ensures insulation between the circuit board 31 and the second substrate 3211, preventing short circuits due to charging of the heat dissipation support 32, and improving the operational reliability of the energy storage power supply. The relief holes 351 provided in the insulating plate 33 ensure that the heat conductive pads 312 make direct contact with the second substrate 3211, and that heat on the circuit board 31 is quickly conducted to the heat dissipation support 32, thereby improving the heat dissipation efficiency of the inverter 30.

[0154] In some implementations, the energy storage power supply 100 further comprises heat tubes, which are thermally coupled to the heat dissipation structure 12.

[0155] Specifically, the heat tube is typically a sealed copper tube with a phase change medium inside, possessing excellent thermal conductivity. In this invention, the heat tube is installed in the housing cavity 132 and in close contact with the heat dissipation structure 12. Heat is mainly generated from the inverter 30, and because the amount of heat generated by the different power elements 311 of the inverter 30 differs, different areas of the heat dissipation structure 12 will have different temperatures, and areas with extremely high temperatures may appear.

[0156] Therefore, in this invention, it is possible to conduct heat from the high-temperature zone to the low-temperature zone using a heat tube, thereby achieving uniform heat dissipation of the heat dissipation structure 12, resulting in better heat dissipation and a better heat dissipation effect.

[0157] As shown in Figure 2, in some implementations, the battery module 20 can be positioned above the inverter 30, and a protective plate 21 can be installed on one side of the battery module 20 facing the inverter 30, with the protective plate 21 used to protect the battery module 20.

[0158] More specifically, the protective plate 21 prevents the inverter 30 or other external objects from directly contacting the battery module 20, thereby avoiding physical damage that could be caused by friction, collision, or pressure. This is crucial for maintaining the structural integrity of the battery module 20 and extending its service life.

[0159] Furthermore, in some cases, the inverter 30 may generate electromagnetic interference or electrical noise. The protective plate 21 acts as an electrical shield, reducing the impact of these interferences on the battery module 20, ensuring that the battery module 20 can operate stably and safely.

[0160] In addition, while the battery module 20 generates heat during operation, the inverter 30 can also be a heat source. The protective plate 21 provides some degree of insulation, which reduces heat exchange between the battery module 20 and the inverter 30, helping the battery module maintain an appropriate operating temperature range.

[0161] If the inverter 30 experiences a malfunction or abnormality such as a short circuit or overheating, the protective plate 21 acts as an additional safety barrier, preventing these malfunctions from directly damaging the battery module 20. This can also reduce safety risks such as fire and explosion to some extent.

[0162] The above embodiments represent only a few embodiments of the present application and are described in specific and detailed terms, but this should not be understood as limiting the claims of the present application.
