[0039] The embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

These terms are only used to distinguish the same type of information from each other.

Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0041] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0042] Unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0043] Figure 1 and Figure 2 The energy storage device 10 in some embodiments of the utility model is shown, and the energy storage device 10 includes a cabinet 1 and a heat sink 2. It can be understood that the cabinet 1 plays the role of installing the heat sink 2. The heat sink 2 plays the role of cooling and dissipating heat.

[0044] like Figure 3 , Figure 4 and Figure 8 As shown, an energy storage bin 11 is disposed on the cabinet 1 , and a plurality of energy storage storage locations 111 are sequentially disposed in the energy storage bin 11 .

[0045] It can be understood that the energy storage compartment 11 is used to accommodate energy storage devices, and each energy storage storage position 111 corresponds to storing at least one energy storage unit. For example, the energy storage storage position 111 is used to store battery boxes. Further, the number of battery boxes in each energy storage storage position 111 is configured to be at least one. When the number of battery boxes in each energy storage storage position 111 is configured to be multiple, the placement of the battery boxes in each energy storage storage position 111 can be flexibly set, and it is preferred to allow airflow to flow evenly to each battery box. The sequential arrangement of the energy storage storage positions 111 means that each energy storage storage position 111 is arranged equidistantly along the path. For example, each energy storage storage position 111 can be arranged one by one along a straight line, or one by one along two parallel straight lines, or one by one along three or more straight lines. Furthermore, each energy storage storage position 111 can be arranged in an array along the horizontal direction, or one by one along the vertical direction, so as to adapt to different application requirements. The purpose of the one-by-one arrangement is to ensure that the fluid can flow through each energy storage storage position 111 one by one, and to ensure that the energy storage units in each energy storage storage position 111 can obtain the heat dissipation fluid with the same flow rate as much as possible, thereby improving the heat dissipation uniformity.

[0046] like Figures 4 to 8 As shown, the heat dissipation device 2 includes a heat dissipation component 21, a first air duct 22 and at least one second air duct 23. The heat dissipation component 21, the first air duct 22 and the second air duct 23 are respectively arranged on the cabinet 1. The air outlet 211 of the heat dissipation component 21 is connected to the first air duct 22. Each second air duct 23 is provided with a diverter plate 231. Each diverter plate 231 corresponds to each second air duct 23 to define a plurality of air guide channels 232. The inlet end 2321 of each air guide channel 232 is connected to the first air duct 22, and the outlet end 2322 of each air guide channel 232 is exposed in the energy storage bin 11.

[0047] Among them, the heat dissipation component 21 guides the fluid to flow out from the air outlet and flow into the first air duct 22, the fluid is guided to each inlet end 2321 through the first air duct 22, and the fluid is guided to the outlet end 2322 through the air guide channel 232 for discharge, so that the fluid flows through each energy storage storage position 111 one by one along the energy storage bin 11.

[0048] It can be understood that the heat dissipation component 21 is a prior art, which can be set with reference to the air conditioning system on the energy storage cabinet in the prior art, and can also be further configured to be able to blow out fluid below room temperature. The fluid formed in the utility model includes airflow. The blowing port 211 is used to blow out the fluid for heat dissipation. The first air duct 22 is used to collect the fluid flowing out of the blowing port 211, and divert the fluid to each second air duct 23, so as to achieve the initial diversion of the fluid for heat dissipation. When the fluid flows into the inlet end 2321 of each second air duct 23, it will be further diverted to each air guide channel 232 under the obstruction of the diverter plate 231. After the fluid is discharged through the outlet end 2322, it will flow along the energy storage bin 11, so that the fluid for heat dissipation flows through each energy storage storage position 111; wherein, in the process of the fluid flowing through the energy storage storage position 111, the energy storage unit in the energy storage storage position 111 will be cooled. In this way, after two diversions, the heat dissipation fluid generated by the heat dissipation component 21 can flow into the energy storage bin 11 as evenly as possible.

[0049] It should be noted that the arrangement of the diverter plate 231 enables the space in the second air duct 23 to be divided into multiple parts along the flow direction of the fluid, and each part guides the flow of the fluid respectively. The outflow end 2322 is preferably arranged at an upper position in the energy storage bin 11 so that the fluid can flow from top to bottom to avoid gravity affecting the gas flow rate. Of course, according to different design schemes and usage requirements, the outflow end 2322 can also be arranged at other positions in the energy storage bin 11, but it is necessary to ensure that the fluid can flow through each energy storage storage position 111.

[0050] like Figures 6 to 8 As shown, in some embodiments of the energy storage device 10, the heat dissipation device 2 includes two second air ducts 23, the two second air ducts 23 are arranged in parallel, the two inlet ends 2321 are oriented in the same direction and are adjacent to each other, one end of each diverter plate 231 is located at the inlet end 2321, and the other end of each diverter plate 231 is located at the outlet end 2322.

[0051] It can be understood that the inlet ends 2321 of the two second air ducts 23 are adjacent to each other, which means that after the two second air ducts 23 are correctly installed in parallel, the two inlet ends 2321 are both opened on the outer wall at positions adjacent to the adjacent second air ducts 23, thereby reducing the interval between the two inlet ends 2321, so that the fluid can be transported to the two inlet ends 2321 at the same time without expanding the end of the first air duct 22, and at the same time, it is also possible to avoid as much as possible the fluid from being obstructed by other non-flow-guiding structural elements between the two inlet ends 2321, thereby ensuring that the fluid is guided to the two inlet ends 2321 as fully as possible.

[0052] It should be noted that one end of the diverter plate 231 is located at the inlet end 2321, which includes the diverter plate 231 extending beyond the inlet end 2321, the diverter plate 231 is flush with the inlet end 2321, and the diverter plate 231 is located inside the inlet end 2321; similarly, the other end of the diverter plate 231 is located at the outlet end 2322, which also includes the diverter plate 231 being located inside, outside, and flush with the outlet end 2322.

[0053] The two ends of the diverter plate 231 are respectively located at the inlet end 2321 and the outlet end 2322. Its function is to separate the space between the inlet end 2321 and the outlet end 2322 as fully as possible to avoid cross-flow of the fluid on the left and right sides of the diverter plate 231, and ensure that the fluid can flow in a predetermined space after being separated into two parts by the diverter plate 231 from the inlet end 2321, so as to avoid mutual influence between the fluids.

[0054] like Figure 6 As shown, in some embodiments of the energy storage device 10 , one end of the diverter plate 231 is located at the center of the outflow end 2322 ; or one end of the diverter plate 231 is adjacent to the center of the outflow end 2322 .

[0055] It can be understood that setting the end of the diverter plate 231 at the center of the outlet end 2322 or at a position roughly located at the center of the outlet end 2322 can distribute the fluid as evenly as possible to various positions of the outlet end 2322, avoid excessive flow at local positions, and further improve the uniformity of heat dissipation.

[0056] like Figure 7 and Figure 8 As shown, in some embodiments of the energy storage device 10, the energy storage bin 11 includes two parallel energy storage cavities 112, each energy storage cavity 112 is provided with a plurality of energy storage storage positions 111, two second air ducts 23 are correspondingly located above the two energy storage cavities 112, and two outflow ends 2322 are correspondingly exposed above the two energy storage cavities 112. After the fluid is discharged through the outflow ends 2322, it will flow along the energy storage cavity 112 through each energy storage storage position 111.

[0057] It is understandable that the number of energy storage storage positions 111 provided in each of the two energy storage cavities 112 is preferably configured to be equal, so that the number of energy storage units that can be accommodated in each of the two energy storage cavities 112 is equal, so that on the basis of the fluid being evenly distributed to the two second air ducts 23, the flow rate of the fluid flowing out through each second air duct 23 also tends to be the same or equal, so that the amount of heat dissipation fluid distributed to each energy storage cavity 112 also tends to be the same or equal, and the heat dissipation fluid distributed to the energy storage units in each energy storage storage position 111 is as uniform as possible. Therefore, the consistency of each energy storage unit can be further improved, and the performance of the product can be improved.

[0058] like Figures 4 to 7 As shown, in some embodiments of the energy storage device 10, each second air guide duct 23 is provided with a guide elbow 233 connecting the two air guide channels 232, and a filter 234 is provided on the guide elbow 233. The guide elbow 233 guides the fluid to pass through the filter 234 and then flow through each energy storage storage position 111 from top to bottom.

[0059] It can be understood that the guide elbow 233 is used to guide the fluid to adjust the flow direction, ensuring that the fluid after the change of direction can pass through each energy storage storage position 111 one by one. Since the fluid guided by the guide elbow 233 flows from top to bottom through each energy storage storage position 111, each second air duct 23 should be arranged above the energy storage bin 11, that is, above each energy storage storage position 111. The filter 234 plays a filtering role to prevent foreign matter from entering the energy storage bin 11 and causing pollution to each energy storage storage position 111.

[0060] like Figure 7 and Figure 8 As shown, in some embodiments of the energy storage device 10, the energy storage device 10 also includes an energy storage device (the energy storage device is not shown in the figure), the energy storage device includes a plurality of energy storage units, and each energy storage unit is arranged in each energy storage storage position 111 in a one-to-one correspondence.

[0061] It can be understood that the energy storage device is used to store energy, and each energy storage unit is used for charging and discharging. Specifically, the energy storage unit can be configured as a battery box in the prior art or other energy storage elements that can be used in energy storage equipment, and charging and discharging can be achieved through batteries. An energy storage unit is provided in each energy storage storage position 111, and the number of energy storage units is preferably configured to be equal to the number of energy storage storage positions 111.

[0062] In some embodiments of the energy storage device 10, each energy storage unit is provided with a cooling fan and a cooling channel, and an air inlet of each cooling channel faces the flow path of the fluid.

[0063] It is understandable that the energy storage unit can be configured as a battery box in the prior art or other energy storage elements that can be used in energy storage devices. In order to avoid excessive internal temperature, the energy storage unit in the prior art will be provided with a cooling mechanism inside, and the cooling mechanism is usually an air cooling mechanism, which usually requires a rotating cooling fan to drive the gas flow, and then guide the gas to flow along a predetermined trajectory on the energy storage unit through the cooling channel, thereby achieving the purpose of cooling and heat dissipation.

[0064] Therefore, in this embodiment, the air inlet of each cooling channel is configured to face the flow path of the fluid, so that the heat dissipation fluid flowing out of the heat dissipation device 2 can be directly sucked into the air inlet without bypassing the outer wall of the energy storage unit, thereby avoiding flow obstruction to the heat dissipation fluid generated by the heat dissipation device 2 as much as possible.

[0065] like Figure 3 and Figure 8 As shown, in some embodiments of the energy storage device 10, the cabinet 1 is provided with two columns 12 in parallel between the two energy storage bins 11, each column 12 is provided with a receiving groove 121, and the two receiving grooves 121 are opposite to each other; the energy storage device 10 also includes a fire-fighting device 3, the fire-fighting device 3 includes a fire-fighting pipe 31, and the fire-fighting pipe 31 is respectively passed through the two receiving grooves 121.

[0066] It can be understood that the columns 12 play a supporting role. Specifically, multiple connecting columns 20 can be sequentially spliced ​​with two columns 12 to form the main frame 30, wherein the length of each connecting column 20 can be flexibly set, depending on the design specifications of the main frame 30. The columns 12 can be configured to be formed by bending a plate multiple times, or can be configured to be spliced ​​by multiple plates. The receiving groove 121 is used to accommodate the fire pipe.

[0067] like Figure 1 and Figure 2 As shown, in some embodiments of the energy storage device 10, the energy storage device 10 further includes a supporting device 4, such as Fig. 9 As shown, the supporting device 4 includes a base 41, a plurality of pads 42 and a plurality of bolts 43. The base 41 is provided with a plurality of connecting holes 411. Each pad 42 is respectively arranged on the cabinet 1. Each bolt 43 is correspondingly passed through each pad 42. Each bolt 43 is screwed into the connecting hole 411.

[0068] It can be understood that the supporting device 4 plays a role in supporting the cabinet 1. The base 41 is used to support the cabinet 1 from the bottom. The pad 42 can be configured to be fixed to the cabinet 1 by welding, clamping, integral molding or screw connection, or it can be configured to be fixed to the cabinet 1 by locking the bolts 43 with the base 41. The number of bolts 43 can be configured to be equal to the number of connecting holes 411, and the number of connecting holes 411 can be configured to be equal to the number of pads 42. Each pad 42 is correspondingly provided with a bolt 43, and each bolt 43 is correspondingly screwed into a connecting hole 411.

[0069] like Figure 1 , Figure 2 , Figure 5 and Figure 8 As shown, in some embodiments of the energy storage device 10, an electrical compartment 13 is further provided on the cabinet 1, and a plurality of partitions 14 are provided between the electrical compartment 13 and the energy storage compartment 11, and the partitions 14 are connected in sequence.

[0070] It can be understood that the electrical compartment 13 is used to install corresponding electrical components, including but not limited to inverters, control systems, and various monitoring components, and of course, other energy storage cabinets or necessary and commonly used electrical components on energy storage cabinets in the prior art. The partitions 14 can be connected by splicing, thereby improving the assembly production efficiency of the product.

[0071] The implementation of this utility model has the following beneficial effects:

[0072] The utility model relates to an energy storage device, on which a heat dissipation fluid flowing out of a heat dissipation component is uniformly guided to each second air duct through a first air duct, thereby realizing the initial flow division of the heat dissipation fluid; further, a flow division plate is arranged in each second air duct, so that the fluid flowing into each second air duct is further uniformly guided to each air guide channel, thereby realizing the secondary uniform flow division of the heat dissipation fluid;

[0073] Furthermore, by evenly arranging each energy storage storage position, the energy storage units can be placed in order after being installed accordingly, so that the fluid after two diversions can flow evenly through each energy storage storage position, and in the process of flowing through each energy storage storage position, it is diverted to the energy storage units in each energy storage storage position for cooling;

[0074] In summary, the heat dissipation uniformity of the product is greatly improved, so that the temperature of the energy storage units in each energy storage storage position is as same or close as possible, thereby improving the consistency of each energy storage unit.
