[0042] Referring to Figures 1 to 5 The containerized energy storage converter 100 according to the embodiments of the present application comprises:

[0043] The rack 10 is provided with a first mounting area 101 and a second mounting area 102 at intervals, the first mounting area 101 is located below the second mounting area 102, and the rack 10 is provided with a cover plate 13 around the rack 10;

[0044] The base 20 is detachably arranged at the bottom of the rack 10;

[0045] The power distribution module (not shown in the figure) is arranged in the first mounting area 101;

[0046] The energy storage module 30 is arranged in the second mounting area 102, and the energy storage module 30 is electrically connected with the power distribution module; and

[0047] The heat dissipation module 40 is detachably arranged at the top of the rack 10 and above the energy storage module 30, and the heat dissipation module 40 is in communication with the second mounting area 102.

[0048] In the containerized energy storage converter 100 according to the embodiments of the present application, the cover plate 13 is arranged around the rack 10, which can isolate the energy storage module 30 from direct contact with the outside world, thereby improving the sealing performance and safety of the containerized energy storage converter 100. The heat dissipation module 40 is arranged at the top of the rack 10, i.e. above the energy storage module 30, which can effectively dissipate heat for the energy storage module 30 while shielding the energy storage module 30. The base 20 can stably support most of the structures of the containerized energy storage converter 100, thereby improving the stability of the containerized energy storage converter 100. In addition, the overall structure of the containerized energy storage converter 100 is roughly divided into three main parts, i.e. the rack 10, the heat dissipation module 40 and the energy storage module 30, which fully utilizes the internal space of the rack 10 and its own structure, so that the containerized energy storage converter 100 presents a standard container type, which is convenient for the production, manufacturing, storage and transportation of the containerized energy storage converter 100.

[0049] In the embodiment, the overall structure of the containerized energy storage converter 100 is similar to a container. The rack 10 can be a generally cuboid or rectangular body-shaped stainless steel frame structure. The first mounting area 101 and the second mounting area 102 are internal spaces of the rack 10, which are separated by a partition or the like in the middle of the rack 10 and are distributed along the height direction of the rack 10. The first mounting area 101 is located at the relatively lower end of the rack 10, and the second mounting area 102 is located at the relatively upper end of the rack 10. In this way, the power distribution module is arranged at the relatively lower end of the rack 10, and the energy storage module 30 is arranged at the relatively upper end of the rack 10, which facilitates the installation, disassembly, and later maintenance of the energy storage module 30, and also facilitates the correspondence between the energy storage module 30 and the heat dissipation module 40 above the energy storage module 30, thereby achieving a better heat dissipation effect.

[0050] The rack 10 is provided with detachable cover plates 13 around the periphery. The cover plates 13 can be metal plates, such as stainless steel plates, which are detachably arranged around the periphery of the rack 10 by screws, rivets, or clamping. When the cover plates 13 are mounted on the rack 10, they can jointly enclose the first mounting area 101 and the second mounting area 102 with the partition or related structures in the rack 10, and shield the energy storage module 30 in the second mounting area 102 and protect the power distribution module in the first mounting area 101. When the energy storage module 30 and / or the power distribution module need to be installed, disassembled, or maintained, the corresponding cover plates 13 can be detached from the rack 10.

[0051] More specifically, the cover plates 13 corresponding to the energy storage module 30 can be provided with ventilation structures such as ventilation holes or ventilation grooves, so that the cover plates 13 have a certain ventilation and heat dissipation capacity while shielding the energy storage module 30 over a large area.

[0052] The base 20 can be a hollow stainless steel frame structure with a certain height, which is used to stably support the rack 10, the energy storage module 30, the heat dissipation module 40, and the power distribution module of the containerized energy storage converter 100, and to space the rack 10 from the ground by a certain height, thereby facilitating ventilation and heat dissipation, and reducing the influence of dirt, water vapor corrosion, and the like on the bottom of the equipment. The base 20 can be detachably arranged at the bottom of the rack 10 by screws, rivets, or other fasteners, or can be detachably arranged with the rack 10 by clamping structures, limiting structures, or other assembly structures.

[0053] More specifically, the corresponding connection between the bottom of the rack 10 and the base 20 can be used as a wire passage for the grounding wire. Specifically, a through hole can be formed in the base 20, and the grounding wire of the containerized energy storage converter 100 can be extended from the bottom of the rack 10 to the through hole for grounding, thereby ensuring the electrical safety of the containerized energy storage converter 100.

[0054] In the embodiment, the energy storage module 30 includes a plurality of energy storage devices 301 (not shown) arranged vertically and side by side. Figure 8Each energy storage device 301 is electrically connected with the power distribution module, and the energy storage device 301 is a device capable of realizing energy storage and related functions in the prior art, and the structure thereof is not specifically limited here.

[0055] The energy storage module 30 is detachably arranged in the second mounting area 102, and since the weight of the energy storage module 30 is generally large, a guide rail or a slide rail or the like structure can be arranged on the rack 10 corresponding to the second mounting area 102 to facilitate the sliding dismounting and mounting of the energy storage module 30.

[0056] In the embodiment, the power distribution module can be used to control the power supply, power output and power distribution of the energy storage module 30, so as to protect and segment the circuit of the assembled energy storage converter 100, for example, when a certain energy storage device 301 in the energy storage module 30 is damaged or needs to be powered off, the power distribution module can disconnect the power supply and power output of the corresponding energy storage device 301 and switch to other energy storage devices 301 that can be normally used / output.

[0057] The actual structure of the power distribution module is not specifically limited here, as long as the above functions can be realized.

[0058] In the embodiment, the heat dissipation module 40 can be a forced air cooling and / or liquid cooling heat dissipation structure, and the heat dissipation range thereof covers the top of the energy storage module 30, and the heat output direction is upward, i.e., the top of the assembled energy storage converter 100, so that the heat generated by the energy storage module 30 can be effectively output to the outside, thereby ensuring the normal operation of the assembled energy storage converter.

[0059] The rack 10, the base 20 and the heat dissipation module 40 can all be substantially rectangular bodies, and the sizes of the corresponding surfaces of the three are the same or similar, i.e., the sizes of the upper and lower surfaces of the three are the same or similar, thereby ensuring the high integration when assembled together, so that the overall profile of the assembled energy storage converter 100 can be substantially in the shape of a container.

[0060] Exemplarily, the assembly sequence of the assembled energy storage converter 100 of the embodiment of the utility model can be that the rack 10 is first fixed on the base 20 with screws, then the heat dissipation module 40 is hoisted on the top of the rack 10 and fixed with screws and the cross beam, the power distribution module is installed in the first mounting area 101, the cover plate 13 around the first mounting area 101 is installed on the rack 10, the energy storage module 30 is installed in the second mounting area 102, and then the cover plate 13 around the second mounting area 102 is installed on the rack 10, i.e., the overall installation is completed.

[0061] Please refer to Figures 1 to 5Further, the rack 10 comprises a first rack 11 and a second rack 12 arranged vertically and side by side, the lower space of the first rack 11 and the lower space of the second rack 12 jointly form a first installation area 101, and the upper space of the first rack 11 and the upper space of the second rack 12 jointly form a second installation area 102.

[0062] The energy storage module 30 comprises a first energy storage assembly 31 and a second energy storage assembly 32, the first energy storage assembly 31 is arranged in the upper space of the first rack 11, and the second energy storage assembly 32 is arranged in the upper space of the second rack 12, and the power distribution module is arranged in the lower space of the first rack 11 and / or the lower space of the second rack 12.

[0063] Specifically, the first rack 11 and the second rack 12 are substantially the same structure, both are rectangular body-shaped stainless steel frame structures, the upper space is used for installing the energy storage module 30, and the lower space is used for installing the power distribution module, Figure 3 And Figure 4 As shown in the first rack 11 and the second rack 12, the inner side of the first rack 11 and the second rack 12 is provided with a detachable cross beam, which separates the first rack 11 and the second rack 12 and improves the structural strength of the first rack 11 and the second rack 12, and the lower part of the first rack 11 and the second rack 12 is provided with a detachable partition, so that the first rack 11 and the second rack 12 are relatively independent devices, at this time, the first installation area 101 and the second installation area 102 are both spaced as two spaces.

[0064] Further, the power distribution module can comprise a first power distribution assembly electrically connected with the first energy storage assembly 31 and a second power distribution assembly electrically connected with the second energy storage assembly 32, which are arranged in the lower space of the first rack 11 and the lower space of the second rack 12, respectively, so that the first rack 11, the first energy storage assembly 31 and the first power distribution assembly can be produced, transported, used and maintained as an independent first energy storage converter 100, the second rack 12, the second energy storage assembly 32 and the second power distribution assembly can be produced, transported, used and maintained as another independent second energy storage converter 100, saving the cost of production, transportation and maintenance of the assembled energy storage converter 100.

[0065] It should be noted that the first energy storage assembly 31 is a mirror image machine, that is, the energy storage devices 301 in the assembly are not symmetrically arranged, but are mirror image arranged, and the second energy storage assembly 32 is a non-mirror image machine, that is, the energy storage devices 301 in the assembly are not mirror image arranged, but are symmetrically arranged.

[0066] In the embodiment, the number of the cross beams is determined according to the height of the first energy storage assembly 31 and the second energy storage assembly 32, for example, the cross beams can be 2, corresponding to the top and bottom of the first energy storage assembly 31 / second energy storage assembly 32 respectively, which ensures the stability of the structure while controlling the structural complexity of the control rack 10.

[0067] Please refer to Figures 1 to 2 Further, the side of the first rack 11 and the side of the second rack 12 on the same side of the rack 10 are detachably connected by at least one first cross beam 14; the top edge of the first rack 11 and the top edge of the second rack 12 on the same side of the rack 10 are detachably connected by a second cross beam 15.

[0068] In the embodiment, the side of the first rack 11 and the side of the second rack 12 on the same side of the rack 10 can be understood as follows: since the first rack 11 and the second rack 12 are arranged side by side, both the first rack 11 and the second rack 12 have a side for constituting a certain side surface of the rack 10 (such as the right side of the rack 10 shown in Figure 1 or Figure 2 ), and a top edge for constituting a certain upper edge of the rack 10 (such as the upper edge of the right side of the rack 10 shown in Figure 1 or Figure 2 ).

[0069] That is, the side of the first rack 11 and the side of the second rack 12 for jointly constituting a side surface of the rack 10 are on the same side of the rack 10, and the top edge of the first rack 11 and the top edge of the second rack 12 for jointly constituting an upper edge of the rack 10 are on the same side of the rack 10.

[0070] In the embodiment, the first rack 11 and the second rack 12 are detachably connected by the first cross beam 14 to form the overall rack 10, for example, the first cross beam 14 can be fixed between the first rack 11 and the second rack 12 by screws or rivets and the like fasteners, and the first cross beam 14 can be arranged at the middle and / or bottom of the first rack 11 and the second rack 12, which simply, effectively and stably realizes the assembly of the first rack 11 and the second rack 12.

[0071] Further, the middle and bottom of the first rack 11 correspond to the middle and bottom of the second rack 12, which are detachably connected by the first cross beam 14, thereby ensuring the structural stability when the rack 10 is assembled.

[0072] On the basis of being connected between the first rack 11 and the second rack 12 by the first cross beam 14, the second cross beam 15 is installed in contact with the entire top edge of the first rack 11 and the second rack 12, which further promotes the structural stability of the rack 10. Similarly, the detachable arrangement of the second cross beam 15 can be realized by screws or rivets and the like fasteners.

[0073] In the embodiment, the first cross beam 14 and the second cross beam 15 are arranged on both sides of the rack 10 along the width direction of the rack 10, so as to ensure that the structure of the rack 10 is stable enough.

[0074] Referring to Figure 1 and Figure 2 Furthermore, the heat dissipation module 40 is detachably arranged on the rack 10 through the second cross beam 15.

[0075] In the embodiment, the second cross beam 15 is higher than the top edges of the first rack 11 and the second rack 12, so that the second cross beam 15 can be in overall contact with the lower edges of the corresponding sides of the heat dissipation module 40. The second cross beam 15 and the heat dissipation module 40 can be fixed by screws or rivets and the like, which is convenient for dismounting and mounting and has high stability.

[0076] Through the second cross beam 15, the top of the first rack 11 and the top of the second rack 12 are connected, so that the first rack 11 and the second rack 12 are combined into the rack 10, and the heat dissipation module 40 is detachably arranged on the top of the rack 10, which controls the structural complexity of the containerized energy storage converter 100 and saves the assembly cost.

[0077] Referring to Figure 1 , Figure 2 and Figure 6 Furthermore, the heat dissipation module 40 comprises:

[0078] a heat dissipation shell 41, the heat dissipation shell 41 is provided with air holes 411 around;

[0079] a plurality of heat dissipation fans 42 arranged on the top of the heat dissipation shell 41;

[0080] a heat radiator 43 arranged in the heat dissipation shell 41, and the plurality of heat dissipation fans 42 are located above the heat radiator 43; and

[0081] a liquid cooling pipe connecting the heat radiator 43 and the energy storage module 30.

[0082] Specifically, the heat dissipation shell 41 can be a metal shell in the shape of a generally rectangular body, which has high structural strength and good heat absorption and dissipation capacity. The heat dissipation fan 42 is an exhaust fan, which can effectively output the heat absorbed by the heat dissipation module 40 (i.e. the heat radiator 43) to the outside, i.e. to the top of the containerized energy storage converter 100. The heat radiator 43 is a metal heat radiator 43 in the shape of a generally plate, which is used to absorb the heat generated by the energy storage module 30 in a large area. The heat dissipation fan 42 located above the heat radiator 43 can exhaust the hot air for heat dissipation. The energy storage module 30 itself has a flow channel through which liquid can pass, and the heat radiator 43 also has a flow channel. The flow channel of the heat radiator 43 and the flow channel of the energy storage module 30 are connected through the liquid cooling pipe, so as to realize high-efficiency liquid cooling.

[0083] In the embodiment, the plurality of heat dissipation fans 42 are arranged in two rows along the length direction of the heat dissipation shell 41, and the heat sink 43 is V-shaped and has two blocks corresponding to the two rows of heat dissipation fans 42 respectively, so as to ensure the effective heat absorption and dissipation of the heat dissipation module 40.

[0084] As shown in Figure 1 With Figure 2 In the embodiment, the first side plate of the heat dissipation shell 41 extends in the length direction, and the second side plate extends in the width direction. The air holes 411 are densely arranged on the first side plate, and the air holes 411 are arranged on the second side plate according to the shape of the heat sink 43.

[0085] That is, the second side plate does not arrange the air holes 411 corresponding to the upward part of the heat sink 43, and only arranges the air holes 411 corresponding to the downward part of the heat sink 43 and the part not corresponding to the heat sink 43, so as to ensure that the air entering the heat dissipation shell 41 always passes through the heat sink 43 from the bottom of the heat sink 43 to be extracted upward by the heat dissipation fan 42, so as to ensure the effective heat dissipation of the heat sink 43 and avoid the air entering the heat dissipation shell 41 from other directions to cause turbulence.

[0086] Please refer to Figure 6 Further, in the width direction of the rack 10, the heat sink 43 is inclined from the inside to the outside relative to the heat dissipation shell 41.

[0087] The heat sink 43 is inclined from the inside to the outside relative to the heat dissipation shell 41, that is, the side of the heat sink 43 towards the inside of the heat dissipation shell 41 is lower than the side of the heat sink 43 towards the outside of the heat dissipation shell 41. The side of the heat dissipation shell 41 extending in the length direction is opposite to the heat sink 43, so that the dense air holes 411 are opposite to the heat sink 43. It can be understood that, in the case that the internal space of the heat dissipation shell 41 is limited, the heat sink 43 of larger size can be accommodated in the inclined direction in the heat dissipation shell 41, so as to increase the heat dissipation area of the heat sink 43, and achieve the purpose of improving the heat dissipation effect of the heat dissipation module 40.

[0088] In an embodiment, the included angle between the heat sink 43 and the bottom plate of the heat dissipation shell 41 can be 30 degrees, that is, the inclination angle of the heat sink 43 is 30 degrees.

[0089] Further, a plurality of connecting heads are arranged between the first mounting area 101 and the second mounting area 102, and the connecting heads are located on the bottom plate of the rack 10 where the second mounting area 102 is located.

[0090] Specifically, the connecting head can be a luer, and the connecting heads arranged on the bottom plate are in groups, each group of connecting heads corresponding to each energy storage device 301 of the energy storage module 30, and the energy storage module 30 and the power distribution module are electrically connected through a plurality of groups of connecting cables. Each group of connecting cables passes through a corresponding group of connecting heads and then enters the first mounting area 101. The connecting head can fix and limit the connecting cable between the energy storage device 301 and the power distribution module, so that the connecting cable is arranged in order, facilitating wiring and disconnection, etc.

[0091] Please refer to Figure 5 Furthermore, the top and bottom of the rack 10 where the second mounting area 102 is located are respectively provided with an upper rail set 16 and a lower rail set 17, and the energy storage module 30 is vertically inserted between the upper rail set 16 and the lower rail set 17.

[0092] Specifically, the upper rail set 16 and the lower rail set 17 have the same structure but different orientations, and are oppositely arranged. The upper rail set 16 and the lower rail set 17 each include a plurality of pairs of oppositely arranged upper rails and lower rails. For a single energy storage device 301, a pair of upper rails and a pair of lower rails are vertically inserted therebetween. The upper rail set 16 and the lower rail set 17 guide and limit the top and bottom of the energy storage module 30, and can smoothly and stably guide the installation and disassembly of the energy storage module 30, facilitating the smooth and stable vertical pushing and pulling of the energy storage module 30.

[0093] In addition, the lower rail set 17 is located higher than the connecting head in the above, providing sufficient space for the connecting cable and facilitating the arrangement of the connecting cable.

[0094] Please refer to Figure 1 , Figure 2 With Figure 7 Furthermore, the bottom of the rack 10 is provided with a plurality of third cross beams 18 spaced along the length direction of the rack 10 and extending along the width direction of the rack 10, and the plurality of third cross beams 18 and the base 20 are detachably arranged.

[0095] Specifically, one side of the third cross beam 18 can be welded and fixed with the bottom of the rack 10, or can be detachably arranged with the bottom of the rack 10 through screws, rivets and other fasteners. The other side can be detachably arranged with the base 20 through screws, rivets and other fasteners, thereby realizing the detachable arrangement of the base 20 and the rack 10. The plurality of third cross beams 18 are arranged along the length direction of the rack 10 to relatively stably support the rack 10, thereby realizing the stable installation of the rack 10 and the base 20.

[0096] The number of the third beams 18 is determined based on the bottom size of the rack 10. In the present embodiment, the third beams 18 are two, which can effectively support the rack 10 on the base 20 while controlling the structural complexity of the rack 10.

[0097] In addition, without the base 20, the plurality of third beams 18 and the rack 10 feet can jointly support the rack 10 and other module structures on the rack 10, so that the main structure of the rack 10 is spaced apart from the ground by a certain height, ensuring safety and heat dissipation effect.

[0098] Since the rack 10 is composed of the first rack 11 and the second rack 12, the bottom of the first rack 11 and the bottom of the second rack 12 are each provided with a plurality of beams extending along the width direction of the first rack 11 and the second rack 12. The beams at the bottom of the first rack 11 and the beams at the bottom of the second rack 12 constitute the third beams 18 described above. When the first rack 11 and the second rack 12 are spaced apart by a certain distance, the beams at the bottom of the first rack 11 and the beams at the bottom of the second rack 12 are also spaced apart by a certain distance, that is, the third beams 18 are not a unitary structure.

[0099] Please refer to Figure 1 and Figure 2 Further, the top of the heat dissipation module 40 is uniformly provided with a plurality of detachable lifting rings 44.

[0100] In this way, when installing the containerized energy storage converter 100, it is convenient to hoist and install the heat dissipation module 40 on the top of the rack 10. After the heat dissipation module 40 is installed, the lifting rings 44 can be removed to make the top of the heat dissipation module 40 more regular and beautiful. The lifting rings 44 can also be retained to facilitate the disassembly of the heat dissipation module 40 next time.

[0101] In one embodiment, the lifting rings 44 can be four, and the four lifting rings 44 can be respectively arranged on the four corners of the heat dissipation module 40 (i.e. the heat dissipation shell 41). In this way, the force is more uniform and stable when hoisting the heat dissipation module 40.

[0102] In one embodiment, a threaded structure can be provided at the bottom end of the lifting ring 44, and a corresponding screw hole can be provided at the top of the heat dissipation module 40. That is, the detachable arrangement of the lifting ring 44 on the top of the heat dissipation module 40 is achieved by threaded connection. Not only is the structure simple and convenient to disassemble and install, but also has high stability, which ensures the stable hoisting and movement of the heat dissipation module 40.
