It is widely used in industrial, residential, commercial and other fields.

[0003] However, the heat dissipation effect of the energy storage system in the related art is poor, which affects the service life of the energy storage system. Utility Model Content

[0004] The embodiments of the utility model are intended to solve at least one of the technical problems existing in the prior art.

[0005] To this end, a first aspect of an embodiment of the utility model provides a cabinet assembly.

[0006] A second aspect of the embodiments of the present utility model provides an energy storage device.

[0007] In view of this, according to the first aspect of an embodiment of the utility model, a cabinet assembly is provided, the cabinet assembly is used for an energy storage device, the energy storage device includes an energy storage conversion assembly and a temperature control assembly, the cabinet assembly includes: a cabinet body, the cabinet body is provided with a heat dissipation cavity, an air inlet and an air outlet, the heat dissipation cavity is connected to the air inlet and the air outlet; a partition assembly is arranged in the cabinet body, and the heat dissipation cavity is divided into a first air duct and a second air duct, the first air duct is connected to the air inlet and the air outlet, and the second air duct is connected to the air inlet and the air outlet, the energy storage conversion assembly is located in the first air duct, and the temperature control assembly is located in the second air duct.

[0008] The cabinet assembly provided in the embodiment of the utility model includes a cabinet body and a partition assembly. Specifically, the energy storage device includes an energy storage converter assembly and a temperature control assembly. It can be understood that the energy storage converter assembly includes a high-voltage box and an energy storage converter, one end of the high-voltage box is electrically connected to the energy storage assembly, and the other end of the high-voltage box is electrically connected to the energy storage converter. Optionally, the energy storage device also includes a distribution box, the energy storage converter is electrically connected to the distribution box, and the distribution box is connected to the client load.

[0009] The temperature control component is used to control the surface temperature of the energy storage component. Specifically, the temperature control component can heat or cool the liquid flowing through the energy storage component to keep the energy storage component at an optimal operating temperature.

[0010] It is understandable that since the energy storage inverter component and the temperature control component generate different amounts of heat during operation, the heat dissipation requirements of the energy storage inverter component and the temperature control component are different. Generally, the power of the fan used for heat dissipation in the temperature control component is greater than the power of the fan used for heat dissipation in the energy storage inverter component to meet different heat dissipation requirements.

[0011] Since the power of the fan in the temperature control component is greater than the power of the fan in the energy storage inverter component, the suction force generated by the fan in the temperature control component is greater than the suction force generated by the fan in the energy storage inverter component. When the energy storage inverter component and the temperature control component are located in the same heat dissipation cavity at the same time, the heat dissipation effect of the energy storage inverter component will be affected, which may easily lead to failure of the energy storage inverter component and affect the service life of the energy storage device.

[0012] The partition assembly divides the heat dissipation cavity into a first air duct and a second air duct. The first air duct is connected to the air inlet and the air outlet. The energy storage inverter assembly is located in the first air duct. That is to say, part of the airflow inhaled from the air inlet can flow through the energy storage inverter assembly and then be discharged through the air outlet to achieve heat dissipation of the energy storage inverter assembly.

[0013] The second air duct is connected with the air inlet and the air outlet, and the temperature control component is located in the second air duct. That is to say, part of the airflow inhaled from the air inlet can flow through the temperature control component and then be discharged through the air outlet to achieve heat dissipation of the temperature control component.

[0014] By setting a partition assembly, the heat dissipation cavity is divided into two independent air ducts for respectively dissipating heat for the energy storage inverter assembly and the temperature control assembly, thereby meeting the air intake requirements of the energy storage inverter assembly and the temperature control assembly, thereby significantly improving the problem of the heat dissipation effect of the energy storage inverter assembly being affected by the large suction force of the fan of the temperature control assembly, effectively improving the heat dissipation effect of the energy storage device, achieving efficient heat dissipation, and helping to reduce the probability of failure of electrical components in the energy storage device and extend the service life of the energy storage device.

[0015] In addition, the energy storage converter component and the temperature control component are integrated in the heat dissipation cavity, which improves the integration of the energy storage device, helps to reduce the overall volume of the cabinet component and reduce the space occupied by the energy storage device.

[0016] In addition, the cabinet assembly provided by the above technical solution of the utility model also has the following additional technical features:

[0017] In some technical solutions, optionally, the partition assembly includes a first partition, which is arranged close to the air inlet. The first partition can separate the air inlet into a first inlet and a second inlet, the first inlet is connected to the first air duct, and the second inlet is connected to the second air duct.

[0018] In this technical solution, it is defined that the partition assembly includes a first partition. Specifically, the first partition is arranged close to the air inlet.

[0019] The first partition separates the air inlet into a first inlet and a second inlet, wherein the first inlet is connected to the first air duct, that is, part of the airflow inhaled from the first inlet can flow through the energy storage inverter component and be discharged through the air outlet to achieve heat dissipation of the energy storage inverter component. The second inlet is connected to the second air duct, that is, part of the airflow inhaled from the second inlet can flow through the temperature control component and be discharged through the air outlet to achieve heat dissipation of the temperature control component.

[0020] That is, the first partition can separate the air inlet, thereby avoiding the problem of the side air intake of the energy storage inverter component being affected by the large suction force of the fan of the temperature control component, meeting the respective air intake requirements of the energy storage inverter component and the temperature control component, effectively improving the heat dissipation effect of the energy storage device, and achieving efficient heat dissipation.

[0021] Optionally, at least a portion of the first partition extends in a horizontal direction, thereby dividing the first air duct and the second air duct into upper and lower air ducts, which is conducive to achieving efficient heat dissipation.

[0022] In some technical solutions, optionally, the partition assembly also includes a second partition, which is arranged close to the air outlet. The second partition can separate the air outlet into a first outlet and a second outlet, the first outlet is connected to the first air duct, and the second outlet is connected to the second air duct.

[0023] In this technical solution, it is defined that the partition assembly also includes a second partition. Specifically, the second partition is arranged close to the air outlet.

[0024] The second partition separates the air outlet into a first outlet and a second outlet, wherein the first outlet is connected to the first air duct, that is, part of the airflow inhaled from the air inlet can flow through the energy storage inverter component and then be discharged through the first outlet to achieve heat dissipation of the energy storage inverter component. The second outlet is connected to the second air duct, that is, part of the airflow inhaled from the air inlet can flow through the temperature control component and then be discharged through the second outlet to achieve heat dissipation of the temperature control component.

[0025] That is, the second partition can separate the air outlet, thereby avoiding the problem of mutual influence between the airflow on the air outlet side of the temperature control component and the energy storage converter component, further improving the heat dissipation effect of the energy storage device and achieving efficient heat dissipation.

Specifically, the mounting member is arranged in the heat dissipation cavity, and the temperature control assembly is arranged on the mounting member. Optionally, the mounting member is provided with a slide rail, and the temperature control assembly is arranged on the slide rail for easy maintenance.

[0030] It is understandable that there is generally a gap between the mounting part and the inner wall of the cabinet. When the airflow sucked in from the air inlet flows through the temperature control component and is discharged from the second outlet, there is a situation where the airflow refluxes through the gap between the mounting part and the inner wall of the cabinet, affecting the heat dissipation effect.

[0031] By arranging a baffle at the gap between the mounting piece and the inner wall of the cabinet, the hot air that flows through the temperature control component and is discharged from the second outlet can be effectively prevented from flowing back through the gap between the mounting piece and the inner wall of the cabinet, thereby further improving the heat dissipation effect of the energy storage device, achieving efficient heat dissipation, and helping to extend the service life of the energy storage device.

[0032] In some technical solutions, optionally, the energy storage device also includes an energy storage component, and the cabinet is also provided with a chamber; the cabinet component also includes a partition, which is arranged in the chamber and divides the chamber into a heat dissipation chamber and an installation chamber, and the installation chamber is used to accommodate the energy storage component; wherein the heat dissipation chamber and the installation chamber are arranged along the height direction of the cabinet.

The heat dissipation chamber is used to accommodate the energy storage and conversion assembly and the temperature control assembly, and the installation chamber is used to accommodate the energy storage assembly.

[0034] Optionally, the partition and the cabinet are an integrated structure. It is understood that the integrated structure has good mechanical properties, and thus can improve the connection strength between the partition and the cabinet, thereby providing good support for the energy storage converter component and the temperature control component. At the same time, it can also achieve a sealed separation of the heat dissipation cavity and the installation cavity, thereby improving the reliability of the energy storage device.

[0035] Moreover, the integrated structure is also conducive to the processing and production of the cabinet components, thereby reducing the manufacturing difficulty of the cabinet components and further reducing the production cost of the cabinet components.

[0036] The heat dissipation cavity and the installation cavity are arranged along the height direction of the cabinet, which is beneficial to reducing the footprint of the energy storage device and simplifying the overall structure while improving the system integration of the energy storage device.

[0037] In some technical solutions, optionally, the energy storage assembly includes a plurality of battery modules, and the cabinet assembly further includes a plurality of support members, and the plurality of support members are spaced apart in the installation cavity along the height direction of the cabinet, and each support member is used to accommodate a battery module.

[0038] In this technical solution, it is defined that the cabinet assembly further includes a plurality of support members. Specifically, each support member is used to accommodate a battery module, thereby providing reliable support for each battery module.

[0039] Multiple support members are arranged at intervals along the height direction of the cabinet, so that multiple battery modules are arranged along the height direction of the cabinet, which is beneficial to further reduce the footprint of the energy storage device and simplify the overall structure while improving the system integration of the energy storage device.

[0040] Optionally, each battery module is provided with a temperature-controlling chamber, which is connected to the temperature-controlling component through a pipeline, and a coolant circulates in the pipeline to control the temperature of the battery module.

[0043] It is understandable that the electrical components of the energy storage device are generally arranged at the bottom of the cabinet. If the coolant used to cool the energy storage assembly leaks, it is easy to cause a short circuit failure of the electrical components.

[0044] By providing a liquid collecting pan at the bottom of the energy storage assembly, the coolant can be collected in case of coolant leakage, effectively preventing the leaked coolant from causing short circuit failures in the electrical components at the bottom of the cabinet, thereby further improving the reliability of the energy storage device.

[0045] In some technical solutions, optionally, the liquid receiving tray is provided with a liquid guiding surface and a liquid drain port, the liquid guiding surface includes a first end and a second end opposite to each other, along the height direction of the cabinet, the first end is higher than the second end, and the liquid drain port is arranged close to the second end.

[0048] In this technical solution, it is specified that the liquid receiving tray is also provided with at least one blocking surface. Specifically, one end of the at least one blocking surface is connected to the liquid guiding surface, and the other end extends obliquely toward the top of the cabinet, that is, the other end extends obliquely upward, thereby blocking the coolant leaked onto the liquid receiving tray from flowing to other positions, which is conducive to further allowing the coolant guided by the liquid guiding surface to be quickly discharged through the drain port.

[0049] Optionally, the number of the blocking surfaces is at least two, and the at least two blocking surfaces are respectively located on both sides of the liquid guiding surface.

[0055] The outer edge of the cover plate extends beyond the outer wall of the cabinet door, which can divert accumulated water or rainwater, thereby effectively preventing a large amount of rainwater from flowing into the chamber through the connection between the cabinet door and the cabinet body, thereby causing failure of the energy storage component, energy storage converter component or temperature control component, thereby extending the service life of the energy storage device.

[0064] Optionally, the cabinet assembly includes both a fireproof component and a heat-insulating component. Specifically, the fireproof component is located between the inner wall of the installation cavity and the heat-insulating component. Alternatively, the heat-insulating component is located between the inner wall of the installation cavity and the fireproof component. The configuration can be made according to actual needs, so that the installation cavity has both heat-insulating function and fire-resistant capability.

[0067] It is understandable that when an energy storage component in the installation cavity malfunctions and generates combustible gas, such as carbon monoxide or hydrogen, the exhaust pressure relief port can be opened by the control valve to discharge the combustible gas in the installation cavity, thereby improving the safety of the energy storage device.

[0068] Optionally, the energy storage device further includes a detection component for detecting the concentration of combustible gas in the installation cavity or the pressure in the installation cavity, and when a set value is reached, the control valve opens the exhaust pressure relief port to achieve active exhaust.

[0069] Optionally, when the concentration or pressure of the combustible gas in the installation cavity reaches a certain value, the control valve can automatically open the exhaust pressure relief port to achieve passive pressure relief and improve the safety of the energy storage device.

[0070] Optionally, the exhaust and pressure relief port includes an exhaust port and a pressure relief port, and the installation cavity is connected to the exhaust port and the pressure relief port; the control valve includes a first valve body and a second valve body, the first valve body is arranged at the exhaust port, and the second valve body is arranged at the pressure relief port.

Specifically, the louvers are arranged at the air inlet, and the dust-proof cotton is arranged on the side of the louver close to the heat dissipation cavity. That is to say, the airflow inhaled from the air inlet needs to flow through the louvers and the dust-proof cotton in sequence, and then flow into the heat dissipation cavity to dissipate the heat of the energy storage inverter component and the temperature control component.

[0087] Furthermore, the energy storage device also includes an energy storage and flow conversion component and a temperature control component, wherein the energy storage and flow conversion component is arranged in the first air duct, and the temperature control component is arranged in the second air duct.

[0088] The energy storage device provided by the embodiment of the utility model includes an energy storage inverter component, a temperature control component and a cabinet component. Specifically, it can be understood that since the energy storage inverter component and the temperature control component generate different amounts of heat when working, the energy storage inverter component and the temperature control component have different heat dissipation requirements. Generally, the power of the fan used for heat dissipation in the temperature control component is greater than the power of the fan used for heat dissipation in the energy storage inverter component to meet different heat dissipation requirements.

[0089] Since the power of the fan in the temperature control component is greater than the power of the fan in the energy storage inverter component, the suction force generated by the fan in the temperature control component is greater than the suction force generated by the fan in the energy storage inverter component. When the energy storage inverter component and the temperature control component are located in the same heat dissipation cavity at the same time, the heat dissipation effect of the energy storage inverter component will be affected, which may easily lead to failure of the energy storage inverter component and affect the service life of the energy storage device.

[0090] The partition assembly divides the heat dissipation cavity into a first air duct and a second air duct. The first air duct is connected to the air inlet and the air outlet. The energy storage inverter assembly is located in the first air duct. That is to say, part of the airflow inhaled from the air inlet can flow through the energy storage inverter assembly and then be discharged through the air outlet to achieve heat dissipation of the energy storage inverter assembly.

[0091] The second air duct is connected with the air inlet and the air outlet, and the temperature control component is located in the second air duct. That is to say, part of the airflow inhaled from the air inlet can flow through the temperature control component and then be discharged through the air outlet to achieve heat dissipation of the temperature control component.

[0092] By setting a partition assembly, the heat dissipation cavity is divided into two independent air ducts for respectively dissipating heat for the energy storage inverter assembly and the temperature control assembly, thereby meeting the air intake requirements of the energy storage inverter assembly and the temperature control assembly, thereby significantly improving the problem of the heat dissipation effect of the energy storage inverter assembly being affected by the large suction force of the fan of the temperature control assembly, effectively improving the heat dissipation effect of the energy storage device, achieving efficient heat dissipation, and helping to reduce the probability of failure of electrical components in the energy storage device and extend the service life of the energy storage device.

[0093] In addition, the energy storage converter component and the temperature control component are integrated in the heat dissipation cavity, which improves the integration of the energy storage device, helps to reduce the overall volume of the cabinet component and reduce the space occupied by the energy storage device.

[0096] In this technical solution, the energy storage inverter assembly and the temperature control assembly are defined to be distributed along the height direction of the cabinet. Optionally, the energy storage inverter assembly is located above the temperature control assembly, which facilitates the liquid pipeline connection between the temperature control assembly and the energy storage assembly located in the space below it, which is conducive to achieving efficient heat dissipation of the energy storage assembly.

[0097] By distributing the energy storage converter components and the temperature control components along the height direction of the cabinet, it is beneficial to improve the system integration of the energy storage device while reducing the footprint of the entire energy storage device, simplifying the overall structure, and reducing the production cost of the energy storage device.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0118] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0119] Refer to the following Figures 1 to 15 The cabinet assembly 100 and the energy storage device 400 provided according to some embodiments of the present invention are described.

[0120] In one embodiment according to the present application, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Fig.15 As shown, a cabinet assembly 100 is proposed, and the cabinet assembly 100 is used for an energy storage device 400, and the energy storage device 400 includes an energy storage and conversion assembly 410 and a temperature control assembly 420. The cabinet assembly 100 includes: a cabinet body 110, and the cabinet body 110 is provided with a heat dissipation cavity 111, an air inlet 112 and an air outlet 113, and the heat dissipation cavity 111 is connected to the air inlet 112 and the air outlet 113; a partition assembly 120, which is arranged in the cabinet body 110 and divides the heat dissipation cavity 111 into a first air duct 130 and a second air duct 140, the first air duct 130 is connected to the air inlet 112 and the air outlet 113, and the second air duct 140 is connected to the air inlet 112 and the air outlet 113, the energy storage and conversion assembly 410 is located in the first air duct 130, and the temperature control assembly 420 is located in the second air duct 140.

[0121] The cabinet assembly 100 provided in the embodiment of the utility model includes a cabinet 110 and a partition assembly 120. Specifically, the energy storage device 400 includes an energy storage converter assembly 410 and a temperature control assembly 420. It can be understood that the energy storage converter assembly 410 includes a high-voltage box and an energy storage converter, one end of the high-voltage box is electrically connected to the energy storage assembly 430, and the other end of the high-voltage box is electrically connected to the energy storage converter. Optionally, the energy storage device 400 also includes a distribution box, the energy storage converter is electrically connected to the distribution box, and the distribution box is connected to the client load.

[0122] The temperature control component 420 is used to control the surface temperature of the energy storage component 430. Specifically, the temperature control component 420 can heat or cool the liquid flowing through the energy storage component 430 to keep the energy storage component 430 at an optimal operating temperature.

[0123] It is understandable that since the energy storage and conversion component 410 and the temperature control component 420 generate different amounts of heat during operation, the energy storage and conversion component 410 and the temperature control component 420 have different heat dissipation requirements. Generally, the power of the fan used for heat dissipation in the temperature control component 420 is greater than the power of the fan used for heat dissipation in the energy storage and conversion component 410 to meet different heat dissipation requirements.

[0124] Since the power of the fan in the temperature control component 420 is greater than the power of the fan in the energy storage and conversion component 410, the suction force generated by the fan in the temperature control component 420 is greater than the suction force generated by the fan in the energy storage and conversion component 410. When the energy storage and conversion component 410 and the temperature control component 420 are both located in the same heat dissipation cavity 111, the heat dissipation effect of the energy storage and conversion component 410 will be affected, which may easily lead to failure of the energy storage and conversion component 410 and affect the service life of the energy storage device 400.

[0125] The partition assembly 120 divides the heat dissipation cavity 111 into a first air duct 130 and a second air duct 140. The first air duct 130 is connected to the air inlet 112 and the air outlet 113. The energy storage and conversion assembly 410 is located in the first air duct 130. That is to say, part of the airflow inhaled from the air inlet 112 can flow through the energy storage and conversion assembly 410 and then be discharged through the air outlet 113 to achieve heat dissipation of the energy storage and conversion assembly 410.

[0126] The second air duct 140 is connected to the air inlet 112 and the air outlet 113, and the temperature control component 420 is located in the second air duct 140. That is, part of the airflow inhaled from the air inlet 112 can flow through the temperature control component 420 and then be discharged through the air outlet 113 to achieve heat dissipation of the temperature control component 420.

[0127] By setting a partition assembly 120, the heat dissipation cavity 111 is divided into two independent air ducts for respectively dissipating heat for the energy storage inverter assembly 410 and the temperature control assembly 420, thereby meeting the air intake requirements of the energy storage inverter assembly 410 and the temperature control assembly 420, thereby significantly improving the problem of the heat dissipation effect of the energy storage inverter assembly 410 being affected by the large fan suction force of the temperature control assembly 420, effectively improving the heat dissipation effect of the energy storage device 400, achieving efficient heat dissipation, and helping to reduce the probability of failure of electrical components in the energy storage device 400 and extend the service life of the energy storage device 400.

[0128] In addition, the energy storage converter assembly 410 and the temperature control assembly 420 are integrated in the heat dissipation cavity 111 , which improves the integration of the energy storage device 400 , helps to reduce the overall volume of the cabinet assembly 100 , and reduces the space occupied by the energy storage device 400 .

[0129] like Figure 7 As shown, in some embodiments, optionally, the partition assembly 120 includes a first partition 121, which is arranged close to the air inlet 112. The first partition 121 can separate the air inlet 112 into a first inlet 114 and a second inlet 115. The first inlet 114 is connected to the first air duct 130, and the second inlet 115 is connected to the second air duct 140.

[0130] In this embodiment, it is defined that the baffle assembly 120 includes a first baffle 121 . Specifically, the first baffle 121 is disposed close to the air inlet 112 .

[0131] The first partition plate 121 separates the air inlet 112 into a first inlet 114 and a second inlet 115, wherein the first inlet 114 is communicated with the first air duct 130, that is, part of the airflow inhaled from the first inlet 114 can flow through the energy storage inverter assembly 410 and be discharged through the air outlet 113 to achieve heat dissipation of the energy storage inverter assembly 410. The second inlet 115 is communicated with the second air duct 140, that is, part of the airflow inhaled from the second inlet 115 can flow through the temperature control assembly 420 and be discharged through the air outlet 113 to achieve heat dissipation of the temperature control assembly 420.

[0132] That is, the first partition 121 can separate the air inlet 112, thereby avoiding the problem that the side air intake of the energy storage and conversion component 410 is affected by the large suction force of the fan of the temperature control component 420, meeting the respective air intake requirements of the energy storage and conversion component 410 and the temperature control component 420, effectively improving the heat dissipation effect of the energy storage device 400, and achieving efficient heat dissipation.

[0133] Optionally, at least a portion of the first partition plate 121 extends in the horizontal direction, thereby dividing the first air duct 130 and the second air duct 140 into upper and lower layers of air ducts, which is conducive to achieving efficient heat dissipation.

[0134] like Figure 2 , Figure 5 and Figure 8 As shown, in some embodiments, optionally, the partition assembly 120 also includes a second partition 122, which is arranged near the air outlet 113. The second partition 122 can separate the air outlet 113 into a first outlet 116 and a second outlet 117. The first outlet 116 is connected to the first air duct 130, and the second outlet 117 is connected to the second air duct 140.

[0135] In this embodiment, it is defined that the partition assembly 120 further includes a second partition 122 . Specifically, the second partition 122 is disposed close to the air outlet 113 .

[0136] The second partition plate 122 separates the air outlet 113 into a first outlet 116 and a second outlet 117, wherein the first outlet 116 is communicated with the first air duct 130, that is, part of the airflow inhaled from the air inlet 112 can flow through the energy storage inverter assembly 410 and then be discharged through the first outlet 116 to achieve heat dissipation of the energy storage inverter assembly 410. The second outlet 117 is communicated with the second air duct 140, that is, part of the airflow inhaled from the air inlet 112 can flow through the temperature control assembly 420 and then be discharged through the second outlet 117 to achieve heat dissipation of the temperature control assembly 420.

[0137] That is, the second partition 122 can separate the air outlet 113, thereby avoiding the problem of mutual influence between the airflow on the air outlet side of the temperature control component 420 and the energy storage conversion component 410, further improving the heat dissipation effect of the energy storage device 400, and achieving efficient heat dissipation.

[0138] Optionally, at least a portion of the second partition plate 122 extends in the horizontal direction, thereby dividing the first air duct 130 and the second air duct 140 into upper and lower layers of air ducts, which is conducive to achieving efficient heat dissipation.

[0139] Optionally, the second partition plate 122 includes an air outlet tube, and the cross-sectional shape of the air outlet tube is circular or quadrilateral.

[0140] like Figure 2 and Figure 5 As shown, in some embodiments, optionally, the cabinet assembly 100 also includes a mounting member 150 and a baffle 160, wherein the mounting member 150 is disposed in the heat dissipation cavity 111 for installing the temperature control assembly 420, and the baffle 160 is disposed at the second outlet 117 and is at least partially located in the gap between the mounting member 150 and the inner wall of the cabinet 110.

[0141] In this embodiment, the cabinet assembly 100 is defined to further include a mounting member 150 and a baffle 160. Specifically, the mounting member 150 is disposed in the heat dissipation cavity 111, and the temperature control assembly 420 is disposed on the mounting member 150. Optionally, the mounting member 150 is provided with a slide rail, and the temperature control assembly 420 is disposed on the slide rail for easy maintenance.

[0142] It is understandable that there is generally a gap between the mounting member 150 and the inner wall of the cabinet 110. When the airflow sucked in from the air inlet 112 flows through the temperature control component 420 and is discharged from the second outlet 117, there is a situation where the air flows back through the gap between the mounting member 150 and the inner wall of the cabinet 110, which affects the heat dissipation effect.

[0143] By providing a baffle 160 at the gap between the mounting member 150 and the inner wall of the cabinet 110, the hot air that flows through the temperature control component 420 and is discharged from the second outlet 117 can be effectively prevented from flowing back through the gap between the mounting member 150 and the inner wall of the cabinet 110, thereby further improving the heat dissipation effect of the energy storage device 400, achieving efficient heat dissipation, and helping to extend the service life of the energy storage device 400.

[0144] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Fig.15 As shown, in some embodiments, optionally, the energy storage device 400 also includes an energy storage component 430, and the cabinet 110 is also provided with a chamber 118; the cabinet assembly 100 also includes a partition 170, the partition 170 is arranged in the chamber 118, and the chamber 118 is divided into a heat dissipation chamber 111 and an installation chamber 119, and the installation chamber 119 is used to accommodate the energy storage component 430; wherein, the heat dissipation chamber 111 and the installation chamber 119 are arranged along the height direction of the cabinet 110.

[0145] In this embodiment, it is defined that the cabinet assembly 100 also includes a partition 170. Specifically, the cabinet body 110 is also provided with a chamber 118. The partition 170 divides the chamber 118 into a heat dissipation chamber 111 and an installation chamber 119. The heat dissipation chamber 111 is used to accommodate an energy storage and conversion assembly 410 and a temperature control assembly 420, and the installation chamber 119 is used to accommodate an energy storage assembly 430.

[0146] Optionally, the partition 170 and the cabinet 110 are an integrated structure. It is understood that the integrated structure has good mechanical properties, and thus can improve the connection strength between the partition 170 and the cabinet 110, thereby providing good support for the energy storage converter assembly 410 and the temperature control assembly 420. At the same time, the heat dissipation cavity 111 and the installation cavity 119 can be sealed and separated, thereby improving the reliability of the energy storage device 400.

[0147] Moreover, the integrated structure is also conducive to the processing and production of the cabinet assembly 100 , thereby reducing the manufacturing difficulty of the cabinet assembly 100 , and further reducing the production cost of the cabinet assembly 100 .

[0148] The heat dissipation cavity 111 and the installation cavity 119 are arranged along the height direction of the cabinet 110 , which is beneficial to improving the system integration of the energy storage device 400 while reducing the footprint of the entire energy storage device 400 and simplifying the entire structure.

[0149] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Fig.15 As shown, in some embodiments, optionally, the energy storage assembly 430 includes a plurality of battery modules 431, and the cabinet assembly 100 further includes a plurality of support members 180, and along the height direction of the cabinet body 110, the plurality of support members 180 are spaced apart in the installation cavity 119, and each support member 180 is used to accommodate a battery module 431.

[0150] In this embodiment, the cabinet assembly 100 further includes a plurality of support members 180 . Specifically, each support member 180 is used to accommodate a battery module 431 , thereby providing reliable support for each battery module 431 .

[0151] Multiple support members 180 are arranged at intervals along the height direction of the cabinet 110, so that multiple battery modules 431 are arranged along the height direction of the cabinet 110, which is beneficial to further reduce the footprint of the energy storage device 400 while improving the system integration of the energy storage device 400 and simplifying the overall structure.

[0152] Optionally, each battery module 431 is provided with a temperature-controlling chamber, which is connected to the temperature-controlling component 420 through a pipeline, and a coolant circulates in the pipeline to control the temperature of the battery module 431 .

[0153] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, optionally, the cabinet assembly 100 further includes a liquid receiving tray 190 , which is disposed in the installation cavity 119 and located at the bottom of the energy storage assembly 430 .

[0154] In this embodiment, it is defined that the cabinet assembly 100 further includes a liquid receiving pan 190 . Specifically, the liquid receiving pan 190 is disposed in the installation cavity 119 , and the liquid receiving pan 190 is located at the bottom of the energy storage assembly 430 .

[0155] It is understandable that the electrical components of the energy storage device 400 are generally arranged at the bottom of the cabinet 110. If the coolant used to cool the energy storage assembly 430 leaks, it is easy to cause a short circuit failure of the electrical components.

[0156] By setting a liquid receiving tray 190 at the bottom of the energy storage assembly 430, the coolant can be collected in case of coolant leakage, effectively preventing the leaked coolant from causing short circuit failures in the electrical components at the bottom of the cabinet 110, further improving the reliability of the energy storage device 400.

[0157] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 7 As shown, in some embodiments, optionally, the liquid receiving tray 190 is provided with a liquid guiding surface 191 and a liquid drain port 193, the liquid guiding surface 191 includes a first end and a second end opposite to each other, along the height direction of the cabinet 110, the first end is higher than the second end, and the liquid drain port 193 is arranged close to the second end.

[0158] In this embodiment, the liquid receiving pan 190 is defined to be provided with a liquid guiding surface 191 and a liquid drain port 193. Specifically, the liquid guiding surface 191 includes a first end and a second end, wherein the first end is higher than the second end along the height direction of the cabinet 110, that is, the liquid guiding surface 191 is an inclined surface, so as to guide the coolant leaking to the liquid receiving pan 190. The liquid drain port 193 is arranged close to the second end, that is, the liquid drain port 193 is arranged close to the lower end, so that the coolant guided by the liquid guiding surface 191 can be quickly discharged through the liquid drain port 193.

[0159] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 7 As shown, in some embodiments, optionally, the liquid receiving tray 190 is further provided with at least one blocking surface 192 , one end of the at least one blocking surface 192 is connected to the liquid guiding surface 191 , and the other end thereof extends obliquely toward the top of the cabinet 110 .

[0160] In this embodiment, it is defined that the liquid receiving pan 190 is also provided with at least one blocking surface 192. Specifically, one end of the at least one blocking surface 192 is connected to the liquid guiding surface 191, and the other end extends obliquely toward the top of the cabinet 110, that is, the other end extends obliquely upward, thereby blocking the coolant leaked onto the liquid receiving pan 190 from flowing to other positions, which is conducive to further allowing the coolant guided by the liquid guiding surface 191 to be quickly discharged through the drain port 193.

[0161] Optionally, the number of the blocking surfaces 192 is at least two, and the at least two blocking surfaces 192 are respectively located on both sides of the liquid guiding surface 191 .

[0162] like Figure 1 , Figure 2 , Figure 4 , Figure 7 and Figure 8 As shown, in some embodiments, optionally, the cabinet 110 includes a cabinet body 210 and a cover plate 220, wherein the cabinet body 210 is provided with a chamber 118 and an air outlet 113, the cover plate 220 is provided at the top of the cabinet body 210, and at least a portion of the outer wall surface of the cover plate 220 is constructed as a slope.

[0163] In this embodiment, the cabinet 110 is defined to include a cabinet body 210 and a cover plate 220.

At least part of the outer wall surface of the cover plate 220 is an inclined surface, which is conducive to avoiding water accumulation on the top of the cabinet 110, thereby preventing the accumulated water from flowing into the chamber 118, and improving the reliability of the energy storage device 400.

[0164] Optionally, the outer wall surface of the cover plate 220 can be configured to be in a herringbone shape or a pagoda top, which can be configured specifically according to actual needs.

[0165] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig.15 As shown, in some embodiments, optionally, the cabinet body 110 also includes a cabinet door 230, which is disposed on the cabinet body 210 and is used to open or close the chamber 118. The cabinet door 230 is provided with an air inlet 112; wherein the outer edge of the cover plate 220 exceeds the outer wall surface of the cabinet door 230.

Specifically, the cabinet door 230 is arranged on the cabinet body 210, and the cabinet door 230 can open or close the chamber 118, so that the operator can open the chamber 118 for maintenance by operating the cabinet door 230, thereby improving the maintenance convenience of the energy storage device 400 and helping to reduce the maintenance cost of the energy storage device 400.

[0167] The outer edge of the cover plate 220 extends beyond the outer wall of the cabinet door 230, which can guide the accumulated water or rainwater, thereby effectively preventing a large amount of rainwater from flowing into the chamber 118 through the connection between the cabinet door 230 and the cabinet body 210, thereby preventing the energy storage component 430, the energy storage conversion component 410 or the temperature control component 420 from malfunctioning, thereby extending the service life of the energy storage device 400.

[0168] like Figure 1 and Figure 6 As shown, in some embodiments, optionally, the cabinet assembly 100 also includes a seal 240 and a locking member 250, wherein the seal 240 is arranged at the connection between the cabinet door 230 and the cabinet body 210, a part of the locking member 250 is arranged on the cabinet body 210, and another part of the locking member 250 is arranged on the cabinet door 230, for locking the cabinet door 230 and the cabinet body 210.

[0169] In this embodiment, it is defined that the cabinet assembly 100 also includes a seal 240 and a locking member 250. Specifically, the seal 240 is arranged at the connection between the cabinet door 230 and the cabinet body 210, thereby sealing the connection between the cabinet door 230 and the cabinet body 210, improving the sealing of the installation cavity 119, and ensuring the reliable operation of the energy storage device 400.

[0170] A portion of the locking member 250 is disposed on the cabinet body 210 , and another portion is disposed on the cabinet door 230 . The cabinet door 230 and the cabinet body 210 can be locked and matched by the locking member 250 , which is beneficial to further improve the sealing of the installation cavity 119 .

[0173] In this embodiment, it is defined that the cabinet assembly 100 also includes an insulation component 260. Specifically, the insulation component 260 is disposed in the installation cavity 119, and the insulation component 260 is connected to the inner wall of the installation cavity 119, so as to insulate the installation cavity 119 and reduce the heat exchange between the installation cavity 119 and the external environment, thereby facilitating ensuring that the energy storage component 430 in the installation cavity 119 is at an optimal operating temperature and reducing the energy consumption of the temperature control component 420.

[0174] like Fig.10 and Fig.11 As shown, in some embodiments, optionally, the cabinet assembly 100 further includes a fireproof member 270 , which is disposed in the installation cavity 119 and connected to an inner wall of the installation cavity 119 .

Specifically, the cabinet body 110 is further provided with an exhaust pressure relief port 280 , wherein the exhaust pressure relief port 280 is in communication with the installation cavity 119 .

[0179] It is understandable that when the energy storage assembly 430 in the installation cavity 119 is abnormal and generates combustible gas, such as carbon monoxide or hydrogen, the exhaust pressure relief port 280 can be opened by the control valve 290 to discharge the combustible gas in the installation cavity 119 and improve the safety of the energy storage device 400.

The specific settings can be made according to actual needs.

[0183] like Figure 2 As shown, in some embodiments, optionally, the cabinet 110 is further provided with a fire interface 310, and the fire interface 310 is communicated with the installation cavity 119 for communicating with a fire extinguishing medium.

[0184] In this embodiment, the cabinet 110 is further provided with a fire interface 310, and specifically, the fire interface 310 is connected to the installation cavity 119. It is understandable that when a fire occurs in the installation cavity 119, a fire extinguishing medium, such as a liquid medium or a gaseous medium, can be provided to the installation cavity 119 through the fire interface 310, thereby realizing rapid fire extinguishing of the energy storage device 400 after the fire occurs, and reducing losses.

[0186] like Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, optionally, the cabinet assembly 100 further includes a blocking member 320 , which is disposed on the cabinet body 110 and located between the air inlet 112 and the heat dissipation cavity 111 .

[0187] In this embodiment, it is defined that the cabinet assembly 100 also includes a blocking member 320. Specifically, the blocking member 320 is disposed on the cabinet body 110, and the blocking member 320 is located between the air inlet 112 and the heat dissipation cavity 111. That is, the airflow sucked in from the air inlet 112 passes through the blocking member 320 and then flows into the heat dissipation cavity 111 to dissipate heat for the energy storage and conversion assembly 410 and the temperature control assembly 420.

[0188] By providing the blocking member 320 , moisture, impurities, etc. in the external environment can be effectively blocked from entering the heat dissipation cavity 111 through the air inlet 112 , thereby reducing the probability of failure of the energy storage inverter component 410 and the temperature control component 420 , and ensuring the reliable operation of the energy storage device 400 .

[0189] Moreover, since the blocking member 320 can block moisture, impurities, etc. in the external environment, it can also prevent moisture, impurities, etc. from entering the fans of the energy storage and conversion component 410 and the temperature control component 420, causing fan failure, thereby affecting the heat dissipation effect of the energy storage and conversion component 410 and the temperature control component 420, which is beneficial to ensure efficient heat dissipation of the energy storage device 400.

[0190] like Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, optionally, the blocking member 320 includes a louver 321 and dust-proof cotton 322 , wherein the louver 321 is disposed at the air inlet 112 , and the dust-proof cotton 322 is disposed on a side of the louver 321 close to the heat dissipation cavity 111 .

[0191] In this embodiment, the blocking member 320 is defined to include a louver 321 and a dust-proof cotton 322. Specifically, the louver 321 is arranged at the air inlet 112, and the dust-proof cotton 322 is arranged on the side of the louver 321 close to the heat dissipation cavity 111. That is to say, the airflow inhaled from the air inlet 112 needs to flow through the louver 321 and the dust-proof cotton 322 in sequence, and then flow into the heat dissipation cavity 111 to dissipate heat for the energy storage inverter component 410 and the temperature control component 420.

[0192] By providing the shutter 321 and the dustproof cotton 322 at the air inlet 112, a double layer of blocking of moisture, impurities, etc. in the external environment is achieved, and the blocking effect is improved, which can further reduce the probability of failure of the energy storage inverter assembly 410 and the temperature control assembly 420, and ensure the reliable operation of the energy storage device 400. At the same time, it further prevents moisture, impurities, etc. from entering the fans of the energy storage inverter assembly 410 and the temperature control assembly 420, causing fan failure, and further affecting the heat dissipation effect of the energy storage inverter assembly 410 and the temperature control assembly 420, which is conducive to further ensuring the efficient heat dissipation of the energy storage device 400.

[0193] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig.12 , Fig.13 , Fig.14 and Fig.15 As shown, in some embodiments, optionally, the cabinet assembly 100 also includes a support base 330, and the support base 330 is arranged at the bottom of the cabinet body 110; wherein the support base 330 is provided with a first interface 331 for hoisting the cabinet assembly 100; and / or the support base 330 is provided with a second interface 332 for grounding; and / or the support base 330 is provided with a third interface 333 for hoisting and forklift transportation of the cabinet assembly 100.

[0194] In this embodiment, it is defined that the cabinet assembly 100 further includes a support base 330 . Specifically, the support base 330 is disposed at the bottom of the cabinet body 110 , thereby providing reliable support for the cabinet body 110 .

[0195] The support base 330 is provided with a first interface 331 . Specifically, the first interface 331 is used for hoisting the cabinet assembly 100 .

[0196] The support base 330 is provided with a second interface 332 . Specifically, the second interface 332 is used for grounding to improve the safety of the energy storage device 400 .

[0197] The support base 330 is further provided with a third interface 333 , and the third interface 333 is used for hoisting and forklift transportation of the cabinet assembly 100 .

[0198] According to a second aspect of the present invention, an energy storage device 400 is provided, comprising a cabinet assembly 100 as provided in any of the above embodiments, and thus having all the beneficial technical effects of the cabinet assembly 100, which will not be described in detail herein.

[0199] like Fig.15As shown, further, the energy storage device 400 also includes an energy storage and flow conversion component 410 and a temperature control component 420 , wherein the energy storage and flow conversion component 410 is disposed in the first air duct 130 , and the temperature control component 420 is disposed in the second air duct 140 .

[0200] The energy storage device 400 provided in the embodiment of the utility model includes an energy storage inverter component 410, a temperature control component 420 and a cabinet component 100. Specifically, it can be understood that since the energy storage inverter component 410 and the temperature control component 420 generate different amounts of heat during operation, the energy storage inverter component 410 and the temperature control component 420 have different heat dissipation requirements. Generally, the power of the fan used for heat dissipation in the temperature control component 420 is greater than the power of the fan used for heat dissipation in the energy storage inverter component 410 to meet different heat dissipation requirements.

[0201] Since the power of the fan in the temperature control component 420 is greater than the power of the fan in the energy storage and conversion component 410, the suction force generated by the fan in the temperature control component 420 is greater than the suction force generated by the fan in the energy storage and conversion component 410. When the energy storage and conversion component 410 and the temperature control component 420 are both located in the same heat dissipation cavity 111, the heat dissipation effect of the energy storage and conversion component 410 will be affected, which may easily lead to failure of the energy storage and conversion component 410 and affect the service life of the energy storage device 400.

[0202] The partition assembly 120 divides the heat dissipation cavity 111 into a first air duct 130 and a second air duct 140. The first air duct 130 is connected to the air inlet 112 and the air outlet 113. The energy storage and conversion assembly 410 is located in the first air duct 130. That is to say, part of the airflow inhaled from the air inlet 112 can flow through the energy storage and conversion assembly 410 and then be discharged through the air outlet 113 to achieve heat dissipation of the energy storage and conversion assembly 410.

[0203] The second air duct 140 is connected to the air inlet 112 and the air outlet 113, and the temperature control component 420 is located in the second air duct 140. That is, part of the airflow inhaled from the air inlet 112 can flow through the temperature control component 420 and then be discharged through the air outlet 113 to achieve heat dissipation of the temperature control component 420.

[0204] By setting a partition assembly 120, the heat dissipation cavity 111 is divided into two independent air ducts for respectively dissipating heat for the energy storage inverter assembly 410 and the temperature control assembly 420, thereby meeting the air intake requirements of the energy storage inverter assembly 410 and the temperature control assembly 420, thereby significantly improving the problem of the heat dissipation effect of the energy storage inverter assembly 410 being affected by the large fan suction force of the temperature control assembly 420, effectively improving the heat dissipation effect of the energy storage device 400, achieving efficient heat dissipation, and helping to reduce the probability of failure of electrical components in the energy storage device 400 and extend the service life of the energy storage device 400.

[0205] In addition, the energy storage converter assembly 410 and the temperature control assembly 420 are integrated in the heat dissipation cavity 111 , which improves the integration of the energy storage device 400 , helps to reduce the overall volume of the cabinet assembly 100 , and reduces the space occupied by the energy storage device 400 .

[0206] like Fig.15 As shown, in some embodiments, optionally, the energy storage and conversion component 410 and the temperature control component 420 are arranged along the height direction of the cabinet 110 .

[0207] In this embodiment, the energy storage and conversion assembly 410 and the temperature control assembly 420 are defined to be distributed along the height direction of the cabinet 110. Optionally, the energy storage and conversion assembly 410 is located above the temperature control assembly 420, so that the temperature control assembly 420 is connected to the energy storage assembly 430 located in the space below it through a liquid pipeline, which is beneficial to achieve efficient heat dissipation of the energy storage assembly 430.

[0208] By distributing the energy storage converter assembly 410 and the temperature control assembly 420 along the height direction of the cabinet 110, it is beneficial to improve the system integration of the energy storage device 400 while reducing the footprint of the entire energy storage device 400, simplifying the overall structure, and reducing the production cost of the energy storage device 400.

[0209] In a specific embodiment, the interior of the cabinet (cabinet assembly 100) is divided into upper and lower compartments through a central partition (partition 170), the upper part is an air-cooled compartment (heat dissipation cavity 111), and the lower part is a liquid-cooled compartment (installation cavity 119), and the space is isolated.

[0210] The upper air-cooled compartment (heat dissipation chamber 111), the liquid cooler (temperature control component 420) and the energy storage inverter component (energy storage inverter component 410) are respectively placed on slides fixed on the cabinet columns, and the energy storage inverter component is located vertically above the liquid cooler. Since the liquid cooler and the energy storage inverter component have their own air inlet and outlet channels to achieve heat exchange, and the suction force of the liquid cooler fan is greater than the suction force of the energy storage inverter component fan, in order to prevent the two components from affecting each other and meet their respective air intake requirements, a partition (first partition 121) is set at the air inlet 112 to cut the air inlet into two layers of air ducts (first air duct 130 and second air duct 140); the cold air enters the cold air chamber (heat dissipation chamber 111) along the air inlet 112, and after being divided into upper and lower parts, it enters the heat dissipation air ducts of the liquid cooler and the energy storage inverter component along the air inlet port for heat exchange.

[0211] In order to prevent the hot air after heat exchange from flowing back along the inside of the cabinet to the cold air chamber (heat dissipation chamber 111), resulting in a decrease in the heat dissipation effect, a duct baffle (baffle 160) is set at the air outlet of the liquid cooler and the energy storage inverter assembly to prevent the hot air from flowing back. At the same time, an independent air outlet channel is set to prevent the two components from affecting each other and affecting the air outlet efficiency.

[0212] In order to prevent the cooling liquid of the battery module (energy storage component 430) from leaking and causing a short circuit in the bottom electrical components, a liquid receiving protective plate (liquid receiving plate 190) is set up between the battery module and the bottom electrical components in the lower liquid cooling chamber (installation cavity 119), and a diversion design is made to discharge the liquid out of the cabinet 110.

[0213] Insulation cotton (insulation component 260) is designed at the corresponding positions of the upper and lower sides, the sides and the front and rear door panels of the liquid cooling chamber to achieve the insulation function and reduce energy consumption. It can also be designed as a fireproof board (fireproof component 270) to provide fire resistance.

[0214] The cabinet top (cover plate 220) can be designed as a herringbone or pagoda top to prevent water accumulation on the cabinet top. At the same time, it extends front and back higher than the surface of the door (cabinet door 230) to prevent a large amount of rainwater from pouring into the door sealing surface (installation cavity 119).

[0215] The cabinet bottom base (support base 330) is designed with both a forklift transportation interface (third interface 333), a bottom lifting interface (first interface 331), and a grounded fixed interface (second interface 332) to provide earthquake resistance.

[0216] The opening (air inlet 112) on the cabinet door 230 is used for air intake, and at the same time, the shutter 321 and dustproof cotton 322 are designed to cover the opening area inside the cabinet door 230, so that the cabinet (cabinet component 100) meets the corresponding protection requirements.

[0217] The cabinet door locking mechanism (locking member 250) is designed on the outside of the sealing surface (installation cavity 119). One set of locking mechanism seals two compartments (heat dissipation cavity 111 and installation cavity 119). It can also be designed as two sets of locking mechanisms to seal the two compartments respectively. In this case, the locking mechanism can be set on the outside or inside of the sealing surface.

[0218] An exhaust and explosion relief window (exhaust and pressure relief port 280) is designed on the cabinet door (cabinet body 110), which has both forced exhaust and explosion relief functions. Two modules can also be designed to realize the forced exhaust and explosion relief functions respectively.

[0219] A water firefighting interface (firefighting interface 310 ) is provided at the rear or lower portion of the cabinet 110 .
