Description

Technical Field

[0001] The utility model relates to the technical field of energy storage cabinets, in particular to a distributed energy storage cabinet. Background Art

[0002] With the continuous development of new energy and energy storage technology, energy storage cabinets will be more widely used in the future. Energy storage cabinets are the basic units of energy storage equipment. The daily storage capacity of an energy storage cabinet reaches 5,500 degrees, which is like a large power bank, equivalent to the daily electricity consumption of more than 500 households. Among them, smart energy storage cabinets and large-capacity energy storage cabinets are the two hot spots in the current development of the industry. Smart energy storage cabinets can not only realize functions such as automatic charging and discharging, energy regulation, but also intelligent prediction and control. Large-capacity energy storage cabinets can meet the power demand in high-energy consumption scenarios such as large industries and cities.

[0003] At present, a large number of energy storage units are installed in energy storage cabinets. The operation of energy storage units generates heat. Although cooling fans and heat dissipation ports are provided on the energy storage cabinets to promote heat dissipation through air circulation inside and outside the cabinets, the heat is concentrated in the energy storage units, and the energy storage units naturally dissipate heat slowly to the outside, especially in hot weather. The external ambient temperature of the energy storage cabinet is also very high, so the single air cooling effect is not ideal. In addition, the cooling fan air inlet on the energy storage cabinet is made smaller for protection and other considerations, resulting in uneven air circulation in the energy storage cabinet and uneven heat dissipation.

DETAILED DESCRIPTION

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention:

[0023] Example 1

[0024] like Figures 1 to 5As shown, the distributed energy storage cabinet of this embodiment includes a cabinet 1, one side of the cabinet 1 is hingedly provided with a cabinet door 10, a partition mechanism 2 is provided inside the cabinet 1, the interior of the cabinet 1 is divided into a plurality of cells 7 by the partition mechanism 2, and an energy storage unit 8 is provided inside the cell 7, an air inlet mechanism 3 is provided inside the cabinet 1 above the cabinet door 10, and the air inlet mechanism 3 is communicated with the internal space of the cell 7, a cooling cavity 4 is provided in the cabinet 1 above the air inlet mechanism 3, and a flow guide mechanism is provided in the cooling cavity 4, a refrigeration box 5 is provided on the top of the cabinet 1, and the refrigeration box 5 is connected to the cooling cavity 4 through a circulation mechanism, and a plurality of heat dissipation ports 6 are provided on both sides of the lower end of the cabinet 1, a shielding plate 9 is provided on the top of the cabinet 1 through a bracket, and the shielding plate 9 is provided above the refrigeration box 5, and the cabinet 1 between the cooling cavity 4 and the air inlet mechanism 3 is configured by a heat conducting plate material, so as to realize the heat conduction and heat dissipation of the energy storage unit 8 in the energy storage cabinet, the heat dissipation by air circulation inside and outside the cabinet 1, and the cooling airflow cooling, and the heat dissipation and air inlet circulation in the cabinet 1 are uniform, and the heat dissipation is fast.

[0025] Specifically, the air inlet mechanism 3 includes an air inlet channel 31, an air inlet plate 32, an air inlet box 33 and a fan 34. The air inlet channel 31 is provided in the cabinet 1 above the cabinet door 10. The cabinet 1 between the air inlet channel 31 and the unit cell 7 is provided with an air inlet plate 32. The air inlet plate 32 is provided with a plurality of evenly distributed air inlets 321. An air inlet box 33 is provided on the cabinet 1 at one end of the air inlet channel 31. The air inlet box 33 is connected to the air inlet channel 31. A fan 34 is provided inside the air inlet box 33. An air guide mechanism is provided inside the air inlet channel 31. The cabinet 1 between the top and the bottom of the cooling cavity 4 is configured with a heat conducting plate material, that is, the heat conducting plate can conduct heat and cool the airflow flowing from the cooling cavity 4 to the air inlet channel 31. Under the action of the fan 34, the air outside the energy storage cabinet enters the interior of the air inlet channel 31 through the air inlet box 33, and enters the cell 7 of the cabinet 1 through the air inlet 321 on the air inlet plate 32. The air inlet channel 31 is adapted to the width of the cabinet 1, and the heat dissipation airflow flows through the entire air inlet channel 31, so that the area over which the heat dissipation airflow enters the cabinet 1 through the air inlet channel 31 is wider and more uniform.

[0026] Furthermore, the air guide mechanism includes a central air guide plate 35 and a downward air guide plate 36. A plurality of central air guide plates 35 are arranged inside the air inlet channel 31. A downward air guide plate 36 is arranged on the top of the air inlet channel 31 between two adjacent central air guide plates 35. The windward surfaces of the central air guide plates 35 and the downward air guide plates 36 are both arranged in an arc-shaped surface structure. When the incoming air flow passes through the central air guide plate 35, it is guided to form a central circulation airflow. The central circulation airflow circulates in the air inlet channel 31 and gradually disperses to form an upward airflow and a downward airflow. The upward airflow encounters the downward air guide plate 36 and is guided to form a downward airflow. The downward airflow and the downward airflow enter the cell 7 of the cabinet 1 from the air inlet 321 on the air inlet plate 32.

[0027] Furthermore, the partition mechanism 2 includes a transverse partition 21, a longitudinal partition 22, a flow port 23 and a heat dissipation fin 24. A plurality of transverse partitions 21 and longitudinal partitions 22 are arranged inside the cabinet 1. The transverse partitions 21 and longitudinal partitions 22 are arranged vertically and staggered. Heat dissipation fins 24 are arranged on opposite sides of the transverse partition 21 and the inner wall of the cabinet 1. The flow port 23 is arranged on the transverse partition 21 and the longitudinal partition 22. The heat dissipation fin 24 is arranged away from the transverse partition 21 and the inner wall of the cabinet 1 on one side thereof and in contact with the outer side of the energy storage unit 8. That is, when the energy storage unit 8 is installed in the cell 7, the opposite sides of the energy storage unit 8 and the side away from the cabinet door 10 are in contact with the heat dissipation fins. The sheets 24 are installed in a close fit, and a heat dissipation circulation channel is formed between two adjacent heat dissipation fins 24 for air heat dissipation circulation. 24, the heat dissipation fins 24 have thermal transfer performance, and the heat dissipation fins 24 transfer heat to the contacted energy storage unit 8, and transfer the operating heat of the energy storage unit 8 to the outside. Moreover, due to the heat dissipation fins 24 arranged inside the unit cell 7, two adjacent heat dissipation fins 24 have a certain circulation space, so that there is space for air circulation between the energy storage unit 8 and the unit cell 7, so that the heat dissipation airflow in the air inlet channel 31 enters the unit cell 7 from the air inlet 321, passes through the heat dissipation fins 24 and circulates from top to bottom through the circulation port 23.

[0028] Furthermore, a dustproof air inlet net is provided in the air inlet box 33 at one end of the fan 34 away from the air inlet channel 31, the baffle plate 9 extends out of the air inlet box 33, a dustproof net is provided in the heat dissipation port 6, and the opening of the heat dissipation port 6 is set downward, which can protect the air inlet and heat dissipation port 6 from dust and rain.

[0029] Furthermore, the circulation mechanism includes a connecting pipe 51 and a circulation pump 52. One end of the refrigeration box 5 is connected to the input end of the circulation pump 52 through the connecting pipe 51, the output end of the circulation pump 52 is connected to one end of the cooling chamber 4 through the connecting pipe 51, and the other end of the cooling chamber 4 is connected to the input end of the refrigeration box 5 through the connecting pipe 51. A controller and a temperature sensor are provided on one side outside the refrigeration box 5. The temperature sensor, the controller and the circulation pump 52 are electrically connected. When the temperature sensor detects that the temperature of the external environment of the energy storage cabinet is higher than the set value, the refrigeration box 5 and the circulation pump 52 are controlled to operate. Under the action of the circulation pump 52, the coolant in the refrigeration box 5 enters the cooling chamber 4 through the connecting pipe 51. The low temperature of the cooling chamber 4 cools the incoming air flow in the air inlet channel 31. The coolant passing through the cooling chamber 4 returns to the refrigeration cycle in the refrigeration box 5 through the connecting pipe 51.

[0030] The method of using this embodiment is as follows: the interior of the cabinet 1 is divided into a number of cells 7 by the transverse partition 21 and the longitudinal partition 22, and the energy storage unit 8 is installed in the cell 7 to realize the separated distributed energy storage. Under the action of the fan 34, the air outside the energy storage cabinet enters the interior of the air inlet channel 31 from the air inlet box 33. Since the central air guide plate 35 and the sinking air guide plate 36 are arranged in the air inlet channel 31, the air intake airflow is guided to form a central circulation airflow when passing through the central air guide plate 35. The central circulation airflow circulates in the air inlet channel 31 and gradually disperses to form an upward airflow and a downward airflow. The upward airflow encounters the sinking air guide plate 36 and guides to form a sinking airflow. The sinking airflow and the downward airflow enter the cell 7 of the cabinet 1 from the air inlet 321 on the air inlet plate 32. Since the transverse partition 21 and the longitudinal partition 22 are both provided with circulation ports 23, and the opposite sides of the transverse partition 21 and the inner wall of the cabinet 1 are both provided with heat dissipation fins 24, the heat conduction transfer performance of the heat dissipation fins 24 is excellent. 24 conducts heat transfer to the contacting energy storage unit 8, and transfers the operating heat of the energy storage unit 8 to the outside. Due to the heat dissipation fins 24 arranged inside the unit cell 7, two adjacent heat dissipation fins 24 have a certain circulation space, so that there is space for air circulation between the energy storage unit 8 and the unit cell 7, so that the heat dissipation airflow in the air inlet channel 31 enters the unit cell 7 from the air inlet 321, passes through the heat dissipation fins 24 and flows from top to bottom through the circulation port 23, and the high-temperature air in the cabinet 1 is discharged from the heat dissipation port 6. The central air guide plate 35 and the sinking air guide plate 36 arranged in the air inlet channel 31 make the heat dissipation air flow in the cabinet 1 uniform. Under the action of the circulating pump 52, the coolant in the refrigeration box 5 enters the cooling chamber 4 through the connecting pipe 51. The low temperature of the cooling chamber 4 cools the air flow in the air inlet channel 31, thereby realizing the combination of heat dissipation of the energy storage unit 8 in the energy storage cabinet, heat dissipation through air circulation inside and outside the cabinet 1, and cooling of the heat dissipation airflow. The heat dissipation air flow in the cabinet 1 is uniform and the heat dissipation is fast.

[0031] Example 2

[0032] The structure of the distributed energy storage cabinet of this embodiment is basically the same as that of the distributed energy storage cabinet of embodiment 1, except that the flow guide mechanism includes a flow guide baffle 41, a flow cavity 42, a communication port 43, an inlet 44 and an outlet 45 (see Figures 1 to 6). An inlet 44 is provided at one end of the cooling chamber 4, and the inlet 44 is connected to the output end of the circulation pump 52 through a connecting pipe 51. An outlet 45 is provided at the other end of the cooling chamber 4, and the outlet 45 is connected to the input end of the refrigeration box 5 through a connecting pipe 51. A plurality of guide baffles 41 are provided inside the cooling chamber 4, and a connecting port 43 is provided at one end of the guide baffle 41. The guide baffle 41 divides the interior of the cooling chamber 4 into a serpentine flow chamber 42. The coolant in the refrigeration box 5 enters the cooling chamber 4 through the circulation pump 52 and the connecting pipe 51 through the inlet 44. The coolant flows through the flow chamber 42 and the connecting port 43 through the entire cooling chamber 4. The coolant in the cooling chamber 4 transfers heat to the air inlet channel 31 through the heat conduction plate, so as to realize the air inlet cooling of the air inlet channel 31, reduce the temperature of the heat dissipation airflow, optimize the heat dissipation of the energy storage cabinet, and form a serpentine flow chamber 32 inside the cooling chamber, so that the air inlet cooling in the air inlet channel 31 is uniform and has a large contact surface.
