Description

Technical Field

[0001] The present disclosure relates to the technical field of energy storage devices, and particularly to an energy storage cabinet. Background Art

[0002] An energy storage cabinet is a device for storing electric energy. The energy storage cabinet includes a plurality of arranged battery modules. The energy storage cabinet often has a heat dissipation problem caused by a large heat generation power, and usually adopts air cooling or a cabinet door type cabinet air conditioner for ventilation and heat dissipation.

[0003] At present, for the air conditioning heat dissipation of the energy storage cabinet, a baffle is usually designed at the air outlet of the air conditioner, and the baffle is used as a flow guide plate to achieve the cooling effect of the air outlet of the air conditioner on the battery module. However, the current flow guide plate design makes the air outlet of the air conditioner concentrated in one place, the utilization rate of the air conditioner is low, the temperature uniformity performance of the battery modules in the energy storage cabinet is poor, and the cooling effect on the inside of the cabinet is not obvious. Summary of the Utility Model

[0004] Based on this, it is necessary to provide an energy storage cabinet to solve the problems of low utilization rate of the air conditioner, poor temperature uniformity performance of the battery modules in the energy storage cabinet, and not obvious cooling effect on the inside of the cabinet.

[0005] An embodiment of the present disclosure provides an energy storage cabinet, which includes a cabinet body, a plurality of battery modules, an air outlet of an air conditioner, and a first flow disturbing member; the cabinet body forms an accommodating space, and the cabinet body includes a cabinet door facing the accommodating space; the plurality of battery modules are accommodated in the accommodating space, and the plurality of battery modules are stacked in sequence along the height direction of the cabinet body; the air outlet of the air conditioner is installed on the cabinet door, and the air outlet of the air conditioner faces the plurality of battery modules; the first flow disturbing member is located between the plurality of battery modules and the air outlet of the air conditioner, and the first flow disturbing member is provided with a plurality of groups of first through holes arranged along the height direction of the cabinet body, and each group of first through holes corresponds to one battery module; and along the height direction of the cabinet body, the number of each group of first through holes gradually increases towards the bottom end of the cabinet body.

[0006] For the energy storage cabinet provided by the embodiment of the present disclosure, the air outlet of the air conditioner is used to convey cold air into the accommodating space, and the cold air flows in the first flow disturbing member and then flows out correspondingly through a plurality of groups of first through holes. Since generally the cold air is concentrated in the upper region of the air outlet of the air conditioner, the air volume in the upper part of the first flow disturbing member is large, but the number of the first through holes in the uppermost group is the least, and the cold air flow velocity coming out of the uppermost first through hole is large but the air volume decreases; at the same time, the number of each group of first through holes of the first flow disturbing member towards the bottom end of the cabinet body gradually increases, the cold air flow velocity coming out of the first through holes close to the upper part is large but the air volume is small, and the cold air flow velocity coming out of the first through holes close to the bottom end of the cabinet body gradually decreases but the air volume gradually increases, so that the cold air volume received by each battery module corresponding to each group of first through holes is roughly kept consistent, and each group of first through holes can evenly, quickly and effectively send the air from the air outlet of the air conditioner to each corresponding battery module, perform overall cooling on the cabinet body, improve the use efficiency of the air conditioner, and ensure the constant temperature and cooling requirements inside the cabinet body.

[0007] In some of these embodiments, the first spoiler includes a first bottom plate, a top side plate, and two first side plates. One end of the top side plate and the two first side plates are respectively connected to the first bottom plate. The first spoiler and the air outlet of the air conditioner enclose a first opening. Multiple groups of first through-holes are formed in the first bottom plate, and each group of first through-holes includes multiple first through-holes arranged side by side in the width direction of the cabinet.

[0008] With such an arrangement, the top side plate and the side plates enable the cold air from the air outlet of the air conditioner to move downward, facilitating the uniform delivery of cold air through the multiple first through-holes on the first bottom plate.

[0009] In some of these embodiments, the first spoiler is also provided with multiple side holes arranged in the height direction of the cabinet, and the multiple side holes are respectively arranged on the two first side plates.

[0010] With such an arrangement, the multiple side holes can convey the cold air to other places in the accommodation space of the cabinet, which is beneficial to the overall cooling of the cabinet.

[0011] In some of these embodiments, the energy storage cabinet further includes a second spoiler. The second spoiler and the first spoiler are arranged at intervals in the height direction of the cabinet. The second spoiler is provided with at least one group of second through-holes arranged in the width direction of the cabinet, and each group of second through-holes corresponds to a battery module.

[0012] With such an arrangement, each group of second through-holes of the second spoiler can evenly, quickly, and effectively send the air from the air outlet of the air conditioner to each corresponding battery module, achieving the overall cooling of the cabinet, improving the use efficiency of the air conditioner, and ensuring the constant temperature and cooling requirements inside the cabinet.

[0013] In some of these embodiments, the second spoiler includes a second bottom plate, a bottom side plate, and two second side plates. One end of the bottom side plate and the two second side plates are respectively connected to three side edges of the second bottom plate. The second spoiler and the air outlet of the air conditioner enclose a second opening, and multiple second through-holes are formed in the second bottom plate.

[0014] With such an arrangement, the bottom side plate and the side plates enable the cold air from the air outlet of the air conditioner to move upward, facilitating the uniform delivery of cold air through the multiple second through-holes on the second bottom plate.

[0015] In some of these embodiments, the top side plate is inclined towards the first opening; the bottom side plate is inclined towards the second opening.

[0016] With such an arrangement, when the cold air from the air outlet of the air conditioner contacts the top side plate or the bottom side plate, it can quickly flow downward or upward, reducing the wind resistance, increasing the flow rate of the air, being beneficial to the rapid entry of the cold air into the interior of the cabinet, and reducing the temperature difference inside the cabinet.

[0017] In some of these embodiments, the first through-hole, the second through-hole, and the side holes are all waist-shaped holes extending along the height direction of the cabinet body; the sizes of the first through-hole and the second through-hole are the same.

[0018] With such a setting, the waist-shaped holes can increase the strength of the first spoiler and the second spoiler, effectively disperse stress, and improve the durability and stability of the first spoiler and the second spoiler; at the same time, the multiple waist-shaped holes extending along the height direction of the cabinet body facilitate the outflow of cold air and the uniform delivery of cold air to the corresponding battery modules.

[0019] In some of these embodiments, both the first spoiler and the second spoiler are of an integral structure.

[0020] With such a setting, the number of parts and the assembly steps in the manufacturing process of the first spoiler and the second spoiler are reduced, the manufacturing efficiency is improved, the production cost is reduced, and the manufacturing and installation of the first spoiler and the second spoiler are facilitated.

[0021] In some of these embodiments, the first spoiler further includes a first mounting portion, the first mounting portion is connected to the first side side plate, and the first mounting portion is provided with a first mounting hole;

[0022] The second spoiler further includes a second mounting portion, the second mounting portion is connected to the second side side plate, and the second mounting portion is provided with a second mounting hole.

[0023] With such a setting, the first mounting hole and the second mounting hole facilitate the connection of the first spoiler and the second spoiler to the pre-door by bolts.

[0024] In some of these embodiments, along the height direction of the cabinet body, the first spoiler and the second spoiler are spaced apart to form an air outlet gap, and the air outlet gap corresponds to at least one battery module.

[0025] With such a setting, the air outlet of the air conditioner is divided into three parts by the first spoiler and the second spoiler. The cooperation of the air outlet gap, the first spoiler, and the second spoiler can evenly, quickly, and effectively deliver the air from the air outlet of the air conditioner to each corresponding battery module, cool the cabinet body integrally, improve the use efficiency of the air conditioner, and ensure the constant temperature and cooling requirements inside the cabinet body.

[0038] Reference Figure 1 , Figure 1 shows the structure of the energy storage cabinet 100 in the embodiments of the present disclosure. The present disclosure relates to the technical field of energy storage devices.

[0039] Combined with Figure 2 and Figure 3 ,the embodiments of the present disclosure provide an energy storage cabinet 100, which includes a cabinet body 1, a plurality of battery modules 2, an air-conditioning air outlet 3, and a first spoiler 4. The cabinet body 1 forms an accommodation space 11, and the cabinet body 1 further includes a cabinet door 12 facing the accommodation space 11, and the cabinet door 12 can movably block or display the accommodation space 11. Exemplarily, the cabinet door 12 faces the accommodation space 11 in the front-rear direction.

[0040] A plurality of battery modules 2 are stacked in sequence along the height direction of the cabinet body 1 and accommodated in the accommodation space 11. Exemplarily, the height direction of the cabinet body 1 is the up-and-down direction. The plurality of battery modules 2 are stacked in sequence from top to bottom in the accommodation space 11. The air outlet 3 of the air conditioner is installed on the cabinet door 12, and the air outlet 3 of the air conditioner faces the plurality of battery modules 2.

[0041] The first spoiler 4 is located between the plurality of battery modules 2 and the air outlet 3 of the air conditioner. Exemplarily, the first spoiler 4 is installed on the air outlet 3 of the air conditioner. The first spoiler 4 is provided with multiple groups of first through holes 411 arranged along the height direction of the cabinet body 1, and each group of first through holes 411 corresponds to one battery module 2; and along the height direction of the cabinet body 1, the number of each group of first through holes 411 gradually increases towards the bottom end of the cabinet body 1. Exemplarily, each group of first through holes 411 has multiple first through holes 411, and the multiple first through holes 411 in each group are arranged at intervals in the left-right direction. The number of the first through holes 411 in the uppermost group is the least, and the number of each group of first through holes 411 increases in sequence from top to bottom.

[0042] In the energy storage cabinet 100 provided by the embodiment of the present disclosure, the air outlet 3 of the air conditioner is used to convey cold air into the accommodation space 11, and the cold air flows in the first spoiler 4 and then flows out correspondingly through multiple groups of first through holes 411. Since generally the cold air is concentrated in the upper region of the air outlet 3 of the air conditioner, the air volume in the upper part of the first spoiler 4 is large, but the number of the first through holes 411 in the uppermost group is the least, and the cold air flow velocity coming out of the uppermost first through hole 411 is large but the air volume is small; at the same time, the number of each group of first through holes 411 in the first spoiler 4 towards the lower region gradually increases, and the cold air flow velocity coming out of the first through holes 411 near the lower region gradually decreases but the air volume gradually increases, so that the cold air volume received by each battery module 2 corresponding to each group of first through holes 411 is roughly kept consistent, and the heat dissipation of the plurality of battery modules 2 is relatively balanced.

[0043] In the energy storage cabinet 100 provided by the embodiment of the present disclosure, each group of first through holes 411 can evenly, quickly and effectively send the air from the air outlet 3 of the air conditioner to each corresponding battery module 2, cool the cabinet body 1 integrally, improve the use efficiency of the air conditioner, and ensure the constant temperature and cooling requirements inside the cabinet body 1.

[0044] Exemplarily, the interval distance between two adjacent groups of first through holes 411 in the up-and-down direction is the same. The interval distance between two adjacent first through holes 411 in each group in the left-right direction is the same. The interval distance between two adjacent first through holes 411 decreases in sequence from top to bottom.

[0045] Exemplarily, four battery modules 2 are stacked inside the cabinet body 1 from top to bottom. Four groups of first through-holes 411 are correspondingly formed in the first spoiler 4 from top to bottom. Among them, the uppermost group of first through-holes 411 includes five first through-holes 411 arranged at intervals from left to right, and the number of the next group of first through-holes 411 increases by a fixed number compared with the number of the previous group of first through-holes 411. Exemplarily, the number of each group of first through-holes 411 from top to bottom is five, seven, nine, and eleven in sequence.

[0046] Exemplarily, the number of battery modules 2 can be more or less. The number of through-hole groups of the first spoiler 4 can also be changed accordingly.

[0047] Exemplarily, the number of battery modules 2 is set according to the height of the cabinet body 1. When the cabinet door 12 is in the closed state, the cold air from the air outlet 3 of the air conditioner passes through the first through-holes 411 and directly faces the battery module 2.

[0048] In other embodiments, the first spoiler 4 can be installed to cover multiple battery modules 2.

[0049] Reference Figure 4 , in some of these embodiments, the first spoiler 4 includes a first bottom plate 41, a top side plate 42 and two first side plates 43. One end of the top side plate 42 and the two first side plates 43 are respectively connected to the first bottom plate 41. The first spoiler 4 and the air outlet 3 of the air conditioner enclose a first opening 44. Multiple groups of first through-holes 411 are formed on the first bottom plate 41, and each group of first through-holes 411 includes a plurality of first through-holes 411 arranged side by side in the width direction of the cabinet body 1.

[0050] With such a setting, the top side plate 42 and the side plates enable the cold air from the air outlet 3 of the air conditioner to move downward, facilitating the uniform delivery of cold air through the multiple first through-holes 411 on the first bottom plate 41.

[0051] Exemplarily, the width direction of the cabinet body 1 is the left-right direction.

[0052] Exemplarily, the first bottom plate 41 is arranged parallel to the cabinet door 12 in the front-rear direction. The top side plate 42 is connected to the upper side edge of the first bottom plate 41. The two first side plates 43 are respectively connected to the left and right side edges of the first bottom plate 41. The top side plate 42 and the two first side plates 43 are designed to face the cabinet door 12 and are buckled on the air outlet 3 of the air conditioner, so that the first opening 44 formed by enclosing the first spoiler and the air outlet 3 of the air conditioner faces downward. Multiple groups of first through-holes 411 penetrate through the first bottom plate 41 from top to bottom and correspond to the battery modules 2. At this time, the cold air from the air outlet 3 of the air conditioner flows downward after contacting the top side plate 42 and the first side plates 43 or flows out through the first through-holes 411.

[0053] Reference Figure 4, in some embodiments, the first spoiler 4 is further provided with a plurality of side holes 431 arranged along the height direction of the cabinet body 1, and the plurality of side holes 431 are respectively arranged on the two first side plates 43. With such an arrangement, the plurality of side holes 431 can convey the cold air to the rest of the cabinet accommodation space 11, which is beneficial to the overall cooling of the cabinet.

[0054] Exemplarily, the side holes 431 of the first side plate 43 are arranged at intervals in the up-and-down direction. The side holes 431 on the two first side plates 43 are correspondingly arranged in the left-and-right direction.

[0055] Exemplarily, the shape of the side hole 431 is the same as that of the first through hole 411. The diameter of the side hole 431 is larger than that of the first through hole 411.

[0056] Reference Figures 1 to 3 , in some embodiments, the energy storage cabinet 100 further includes a second spoiler 5, the second spoiler 5 and the first spoiler 4 are arranged at intervals along the height direction of the cabinet body 1, and the second spoiler 5 is provided with at least one group of second through holes 511 arranged along the width direction of the cabinet body 1, and each group of second through holes 511 corresponds to a battery module 2.

[0057] With such an arrangement, each group of second through holes 511 of the second spoiler 5 can evenly, quickly and effectively send the air from the air outlet 3 of the air conditioner to the corresponding battery module 2, perform overall cooling on the cabinet body 1, improve the air conditioner use efficiency, and ensure the constant temperature and cooling requirements inside the cabinet body 1.

[0058] Exemplarily, the second spoiler 5 is installed at the air outlet 3 of the air conditioner, and the second spoiler 5 is arranged above the first spoiler 4.

[0059] Exemplarily, the dimension of the second spoiler 5 in the up-and-down direction is smaller than the dimension of the first spoiler 4 in the up-and-down direction. The dimension of the second spoiler 5 in the left-and-right direction is the same as the dimension of the second spoiler 5 in the left-and-right direction.

[0060] Exemplarily, the second spoiler 5 is only provided with one group of second through holes 511 arranged at intervals in the left-and-right direction. In other embodiments, the second spoiler 5 may also be provided with multiple groups of second through holes 511 in the up-and-down direction.

[0061] Exemplarily, the number of multiple groups of second through holes 511 may be the same or different.

[0062] Reference Figure 5 , in some embodiments, the second spoiler 5 includes a second bottom plate 51, a bottom side plate 52 and two second side plates 53. One ends of the bottom side plate 52 and the two second side plates 53 are respectively connected to three side edges of the second bottom plate 51. The second spoiler 5 and the air outlet 3 of the air conditioner enclose a second opening 54, and a plurality of second through holes 511 are opened on the second bottom plate 51.

[0063] With such a setting, the cold air from the air outlet 3 of the air conditioner can move upward between the bottom side plate 52 and the side plates, facilitating the uniform delivery of the cold air through the plurality of second through holes 511 on the second bottom plate 51.

[0064] Exemplarily, the second bottom plate 51 is arranged parallel to the cabinet door 12 in the front - rear direction. The bottom side plate 52 is connected to the lower side edge of the second bottom plate 51. The two second side plates 53 are respectively connected to the left and right side edges of the second bottom plate 51. The bottom side plate 52 and the two second side plates 53 are designed towards the cabinet door 12 and fastened to the air outlet 3 of the air conditioner, such that the second opening 54 formed by enclosing the second spoiler and the air outlet 3 faces upward. A set of second through holes 511 are arranged at intervals in the left - right direction and penetrate through the second bottom plate 51 and correspond to one battery module 2. At this time, the cold air from the air outlet 3 of the air conditioner flows upward after contacting the bottom side plate 52 and the second side plates 53 or flows out through the second through holes 511.

[0065] Exemplarily, the distance between the second bottom plate 51 and the air outlet 3 is equal to the distance between the first bottom plate 41 and the air outlet 3.

[0066] Reference Figure 4 and Figure 5 , in some of the embodiments, the top side plate 42 is inclined towards the first opening 44; the bottom side plate 52 is inclined towards the second opening 54.

[0067] With such a setting, when the cold air from the air outlet 3 of the air conditioner contacts the top side plate 42 or the bottom side plate 52, it can flow downward or upward quickly, reducing the wind resistance, increasing the flow rate of the air, being beneficial for the cold air to quickly enter the interior of the cabinet 1, and reducing the temperature difference inside the cabinet 1.

[0068] Exemplarily, the connecting part of the top side plate 42 and the first bottom plate 41 is inclined downward. The connecting part of the bottom side plate 52 and the second bottom plate 51 is inclined upward.

[0069] Exemplarily, both the first spoiler 4 and the second spoiler 5 are sheet metal parts.

[0070] Exemplarily, the inclined settings of the top side plate 42 and the bottom side plate 52 are formed by chamfering the sheet metal.

The size of the first through hole 411 is the same as the size of the second through hole 511.

[0072] With such a setting, the kidney-shaped holes can increase the strength of the first spoiler 4 and the second spoiler 5, effectively disperse stress, and improve the durability and stability of the first spoiler 4 and the second spoiler 5. At the same time, the multiple kidney-shaped holes extending in the height direction of the cabinet body 1 facilitate the outflow of cold air and evenly send the cold air to the corresponding battery modules 2.

[0073] Exemplarily, the length direction of the kidney-shaped holes is the up-down direction.

[0074] In some of the embodiments, the size of the first through hole 411 is the same as the size of the second through hole 511.

[0075] In other embodiments, the first through hole 411 and the second through hole 511 can also be circular, square, rhombic, water-drop-shaped or other shapes. The shape of the first through hole 411 is the same as the shape of the second through hole 511.

[0076] In some of the embodiments, both the first spoiler 4 and the second spoiler 5 are of an integral structure. With such a setting, the number of parts and assembly steps in the manufacturing process of the first spoiler 4 and the second spoiler 5 are reduced, the manufacturing efficiency is improved, the production cost is reduced, and the manufacturing and installation of the first spoiler 4 and the second spoiler 5 are facilitated.

[0077] In other embodiments, both the first spoiler 4 and the second spoiler 5 can be formed by welding a split structure.

[0079] The second spoiler 5 further includes a second mounting portion 55. The second mounting portion 55 is connected to the second side side plate 53, and the second mounting portion 55 is provided with a second mounting hole 551. With such a setting, the first mounting hole 451 and the second mounting hole 551 facilitate the connection of the first spoiler 4 and the second spoiler 5 to the pre-cabinet door 12 by bolts.

[0080] Exemplarily, the first mounting portion 45 is a plate-shaped structure extending in the up-down direction and is designed parallel to the first bottom plate 41. The second mounting portion 55 is a plate-shaped structure extending in the up-down direction and is designed parallel to the second bottom plate 51.

[0081] Exemplarily, both the first mounting hole 451 and the second mounting hole 551 are circular through holes. There are three first mounting holes 451 and they are arranged at intervals in the up-down direction. There are two second mounting holes 551 and they are arranged at intervals in the up-down direction. The size of the first mounting hole 451 is the same as the size of the second mounting hole 551.

[0082] Exemplarily, an installation position is provided at the air outlet 3 of the air conditioner. The first installation hole 451 and the second installation hole 551 are both arranged corresponding to the installation position. The bolt fixes the first spoiler 4 to the air outlet 3 of the air conditioner through the first installation hole 451 and the corresponding installation position. The bolt fixes the second spoiler 5 to the air outlet 3 of the air conditioner through the second installation hole 551 and the corresponding installation position.

[0084] With such an arrangement, the air outlet 3 of the air conditioner is divided into three parts by the first spoiler 4 and the second spoiler 5. The cooperation of the air outlet gap 31, the first spoiler 4 and the second spoiler 5 can evenly, quickly and effectively send the air from the air outlet 3 of the air conditioner to each corresponding battery module 2, cool the cabinet 1 integrally, improve the use efficiency of the air conditioner, and ensure the constant temperature and cooling requirements inside the cabinet 1.

[0085] Exemplarily, from top to bottom, the second spoiler 5 and the first spoiler 4 divide the air outlet 3 of the air conditioner into an upper air outlet part, an air outlet gap 31 and a lower air outlet part. The bottom side plate 52 is above the air outlet gap 31, and the top side plate 42 is below the air outlet gap 31. Therefore, the cold air in the air outlet gap 31 can directly blow to a battery module 2 facing it for cooling.

[0086] Exemplarily, seven battery modules 2 are stacked in the accommodation space 11 from top to bottom. The cold air in the upper air outlet part flows out from a group of second through holes 511 and flows to the first battery module facing it. The cold air in the air outlet gap 31 flows to the second battery module facing it. The cold air in the lower air outlet part flows downward and flows out from four groups of first through holes 411 and flows to the third battery module, the fourth battery module, the fifth battery module and the sixth battery module facing it respectively. The seventh battery module corresponds to the cabinet door 12 part, and the cold air flowing out from below the first opening 44 flows to the seventh battery module. The cold air flowing out from the side holes 431 on the left and right sides flows to the periphery of the battery modules 2 in the accommodation space 11.
