Description

Technical Field

[0001] This application relates to the field of energy storage equipment technology, and more specifically, to an energy storage cabinet. Background Technology

[0002] An energy storage cabinet is an integrated energy storage and management device, typically composed of core components such as a battery system, temperature control device, fire suppression unit, energy conversion system, and intelligent monitoring platform. Its appearance is mostly a standardized cabinet or container-like structure, internally integrating high-density battery packs through modular design, possessing functions such as energy storage, stable output, and peak-valley regulation. It is widely used in new energy power plants, grid frequency regulation, industrial and commercial energy storage, and emergency backup power sources, achieving efficient energy dispatch and system safety control through intelligent management. It is a key infrastructure supporting the flexibility and reliability of new power systems.

[0003] When the energy storage cabinet is working, the battery pack releases heat due to prolonged charging or discharging operations. The high temperature inside the cabinet causes the gas temperature to rise. When the gas comes into contact with the liquid cooling plate, the large temperature difference causes the gas to condense on the liquid cooling plate, forming condensate. The condensate dripping onto the battery pack may cause short circuits, creepage, or even fires. Utility Model Content

At the same time, due to the characteristics of the materials of the first, second, and third insulation components, the generation of condensate on their outer surfaces is further reduced, fundamentally avoiding the generation of condensate. This prevents condensate dripping onto the battery pack, which may cause short circuits, creepage, or even fires, thus improving the service life and safety of the energy storage component.

Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0014] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. It should be noted that, unless otherwise specified, the various features in the embodiments of this application can be combined with each other, and the combined embodiments are still within the protection scope of this application.

[0015] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0016] In the description of this application, it should be noted that the terms "upper," "lower," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0017] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0018] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0019] Existing energy storage cabinets contain multiple battery packs. When these packs operate simultaneously, they release heat. If this heat cannot be dissipated in time, it can affect the lifespan of the battery packs and, in severe cases, lead to fires or other safety accidents. Therefore, existing energy storage cabinets have liquid cooling plates fixed at the bottom of the battery packs. Coolant is circulated through these plates to remove the heat generated by the battery packs. However, when high-temperature gas comes into contact with the liquid cooling plate, the significant temperature difference causes condensation, forming water droplets. These droplets falling onto the battery packs can lead to short circuits, electrical leakage, or even fires. Therefore, this application proposes an energy storage cabinet to prevent the formation of condensate.

[0020] One aspect of the embodiments of this application, such as Figures 1 to 5As shown, an energy storage cabinet 100 is provided, including a cabinet body 101 with a chamber 1011. An energy storage component 110 is disposed in the chamber 1011. The energy storage component 110 includes a battery pack 111, a liquid cooling plate 112, a first insulation component 113, a second insulation component 114, and a third insulation component 115. The battery pack 111 is fixedly disposed on the upper surface of the liquid cooling plate 112. The liquid cooling plate 112 includes a first end 1121 and a second end 1122 that are disposed opposite to each other and protrude from the battery pack 111. The first insulation component 113 and the second insulation component 114 are respectively sleeved on the first end 1121 and the second end 1122. The third insulation component 115 is fixedly disposed on the lower surface of the liquid cooling plate 112.

[0021] Specifically, the energy storage cabinet 100 includes a cabinet body 101 and a cabinet door (not shown in the figure). The cabinet body 101 has a chamber 1011 for accommodating the energy storage component 110. The energy storage component 110 includes a battery pack 111, a liquid cooling plate 112, a first insulation component 113, a second insulation component 114, and a third insulation component 115. The battery pack 111 is fixedly mounted on the upper surface of the liquid cooling plate 112. It should be noted that pipes are provided inside the liquid cooling plate 112, and the coolant flowing through the pipes can remove the heat dissipated by the battery pack 111 during operation. The liquid cooling plate 112 includes a first end 1121 and a second end 1122 disposed opposite to each other. The first end 1121 and the second end 1122 protrude outward relative to the battery pack 111. For example, the first end 1121 is the end closer to the opening of the chamber 1011, and the second end 1122 is the end away from the opening of the chamber 1011. The arrangement of the first end 1121 and the second end 1122 facilitates full contact between the pipes inside the liquid cooling plate and the battery pack 111, allowing the coolant to effectively remove the heat generated by the battery pack 111. The protrusion of the first end 1121 from the battery pack 111 also facilitates the connection between the external liquid cooling pipe 120 and the internal pipes of the liquid cooling plate 112. The first end 1121 and the second end 1122 are respectively fitted with a first insulation member 113 and a second insulation member 114, and a third insulation member 115 is fixedly disposed on the lower surface of the liquid cooling plate 112.

[0022] When the energy storage component 110 is working, the battery pack 111 releases heat due to prolonged charging or discharging operations. This heat causes the gas temperature to rise. When the gas comes into contact with the liquid cooling plate 112, the large temperature difference causes the gas to condense on the liquid cooling plate 112, forming condensate. By respectively sleeved with a first insulation component 113 and a second insulation component 114 at the first end 1121 and the second end 1122 of the liquid cooling plate 112, and fixing a third insulation component 115 on the lower surface of the liquid cooling plate 112, on the one hand, the first insulation component 113, the second insulation component 114 and the third insulation component 115 can slow down the heat transfer between the inside and outside of the liquid cooling plate 112; on the other hand, due to the material properties of the first insulation component, the second insulation component and the third insulation component (the materials are described in detail below), the generation of condensate on their outer surface is further slowed down, and the generation of condensate is fundamentally avoided. This avoids the occurrence of safety accidents such as short circuit, creepage or even fire caused by condensate dripping onto the battery pack 111, thereby improving the service life and safety of the energy storage component 110.

[0023] In some embodiments, the first insulation component 113, the second insulation component 114, and the third insulation component 115 may be foamed silicone, foamed polypropylene, or foamed polyethylene, and there is no specific limitation.

[0024] In some embodiments, the connection between the third insulation component 115 and the liquid cooling plate 112 can be by adhesive bonding, screw connection or snap-fit ​​connection, and there is no specific limitation.

[0025] Optionally, such as Figures 3 to 5 As shown, the first insulation component 113 and the second insulation component 114 respectively have a first through groove 1131 and a second through groove 1141, and the first end 1121 and the second end 1122 are respectively located in the first through groove 1131 and the second through groove 1141.

[0026] Specifically, the first insulation component 113 and the second insulation component 114 are respectively fitted onto the first end 1121 and the second end 1122 via the first through groove 1131 and the second through groove 1141. By providing the first through groove 1131 and the second through groove 1141, the first insulation component 113 and the second insulation component 114 do not need to be connected to the liquid cooling plate 112 with additional adhesives or fasteners. At the same time, the first insulation component 113 and the second insulation component 114 can simultaneously cover the upper surface, end face and lower surface of the liquid cooling plate 112.

[0027] In some embodiments, the shapes of the first through groove 1131 and the second through groove 1141 are the same as the shapes of the first end 1121 and the second end 1122, respectively. For example, if the first end 1121 and the second end 1122 are cuboids, then the first through groove 1131 and the second through groove 1141 are U-shaped grooves adapted to the cuboids.

[0028] Optionally, such as Figure 2 As shown, a liquid cooling pipe 120 is installed in the chamber 1011. The liquid cooling pipe 120 is connected to the liquid cooling plate 112. An insulation layer 130 is wrapped around the outside of the liquid cooling pipe 120.

[0029] Specifically, a liquid cooling pipe 120 is installed inside the chamber 1011. The liquid cooling pipe 120 includes an inlet pipe and an outlet pipe, which are connected to the internal piping of the liquid cooling plate 112. Coolant enters the liquid cooling plate 112 through the inlet pipe, absorbs the heat dissipated by the battery pack 111, and then flows out through the outlet pipe. An insulation layer 130 is wrapped around the outside of the liquid cooling pipe 120. The insulation layer 130 prevents condensation from forming on the outer wall of the liquid cooling pipe 120. Optionally, such as Figure 2 and Figure 4 As shown, the liquid cooling pipe 120 is connected to the liquid cooling plate 112 via the adapter 140. The first insulation member 113 is provided with a through hole 1132 and a deformable gap 1133 connecting the through hole 1132 and the opening of the first through groove 1131. The adapter 140 passes through the deformable gap 1133 and is inserted into the through hole 1132. The first insulation member 113 at least partially covers the adapter 140.

[0030] Specifically, the inlet and outlet pipes of the liquid cooling pipe 120 are connected to the liquid cooling plate 112 via an adapter 140. The first insulation component 113 is provided with a through hole 1132 and a deformable gap 1133, which connects the through hole 1132 and the opening of the first through groove 1131. When the first insulation component 113 needs to be installed, the opening of the first through groove 1131 is oriented towards the first end 1121, and the first insulation component 113 is moved so that the adapter 140 passes through the deformable gap 1133 and is inserted into the through hole 1132. At this time, the first insulation component 113 at least partially covers the adapter 140.

[0031] In some implementations, the adapter 140 may also be wrapped with an insulation layer 130. Optionally, such as Figure 2 As shown, a dehumidifier 150 is also installed in the chamber 1011. The dehumidifier 150 is equipped with a drain pipe 151. The dehumidifier 150 is used to discharge condensate to the outside of the energy storage cabinet 100 through the drain pipe 151.

[0032] Specifically, a dehumidifier 150 is installed inside chamber 1011. The dehumidifier 150 draws humid air from inside the energy storage cabinet 100 into its body, condenses the water vapor in the air into condensate water using cooling or adsorption methods, collects the condensate water, and then discharges the dried air, thereby reducing the ambient humidity. The dehumidifier 150 is also equipped with a drain pipe 151, through which the condensate water collected by the dehumidifier 150 is discharged to the outside of the energy storage cabinet 100.

[0033] In some implementations, the dehumidifier 150 can be a condensing dehumidifier 150 or a rotary dehumidifier 150, and the specific type is not limited.

[0034] In some implementations, the dehumidifier 150 may have a capacity of 1 L / D (one liter per day), 4 L / D (four liters per day), or 7 L / D (seven liters per day), which can be selected according to specific circumstances and is not limited here.

[0035] Optionally, a controller and a humidity sensor are also provided in the chamber 1011. The controller is electrically connected to the dehumidifier 150 and the humidity sensor respectively. The controller controls the on / off of the dehumidifier 150 according to the humidity value monitored by the humidity sensor.

[0036] Specifically, a controller and a humidity sensor are installed inside chamber 1011. The controller is electrically connected to both the dehumidifier 150 and the humidity sensor. The humidity sensor monitors the humidity level inside chamber 1011 and transmits this value to the controller. The controller then controls the dehumidifier 150 to turn on and off based on the humidity level. It should be noted that the controller can also control the operating power of the dehumidifier 150. For example, if the humidity sensor detects a high humidity level, the controller will control the dehumidifier 150 to operate in high-power mode. In some implementations, the humidity sensor may be a capacitive humidity sensor, a resistive humidity sensor, or a thermal conductivity humidity sensor, and there is no specific limitation.

[0037] Optionally, such as Figure 4 and Figure 5 As shown, notches 116 are provided on the side walls of the first insulation component 113 and the second insulation component 114. The notches 116 are used to avoid the connectors connecting the battery pack 111 and the liquid cooling plate 112.

[0038] Specifically, a notch 116 is provided on one side wall of the first insulation member 113 and the second insulation member 114 on the upper surface of the liquid cooling plate 112. The battery pack 111 and the liquid cooling plate 112 are connected by a connector. When the first insulation member 113 is fitted onto the first end 1121, the notch 116 can provide a space for the connector. It should be noted that a notch 116 can also be provided on one side wall of the lower surface of the first insulation member 113 and the second insulation member 114. The notch 116 can be used to avoid screws or clips when the third insulation member 115 is connected to the liquid cooling plate 112 by screws or clips.

[0039] Optionally, such as Figure 2As shown, a first fixing plate 160 and a second fixing plate 170 are fixedly installed on the inner wall of the chamber 1011. The first fixing plate 160, the second fixing plate 170 and the inner wall of the chamber 1011 form a receiving groove, and the liquid cooling plate 112 is fixedly installed in the receiving groove.

[0040] Specifically, the first fixing plate 160, the second fixing plate 170, and the inner wall of the chamber 1011 form a receiving groove, and the two ends of the liquid cooling plate 112, which are opposite to the first end 1121 and the second end 1122, are fixedly disposed in the receiving groove. The liquid cooling plate 112 serves to cool the battery pack 111 and also supports the battery pack 111 within the chamber 1011.

[0041] In some embodiments, the connection between the first fixing plate 160 and the second fixing plate 170 and the inner wall of the chamber 1011 can be a screw connection, a snap-fit ​​connection or an adhesive connection, and there is no specific limitation.

[0042] Optionally, such as Figure 2 As shown, a reinforcing member 180 is also fixedly installed on the inner wall of the chamber 1011, and the reinforcing member 180 abuts against the side of the second fixing plate 170 away from the first fixing plate 160.

[0043] Specifically, a reinforcing member 180 is provided on the side of the second fixing plate 170 away from the first fixing plate 160, which can provide additional support for fixing the liquid cooling plate 112.

[0044] Optionally, such as Figure 1 As shown, the chamber 1011 is provided with multiple workstations 190, which are arranged in sequence along the vertical direction. Each workstation 190 is provided with an energy storage component 110.

[0045] Specifically, multiple workstations 190 are arranged vertically within chamber 1011, for example, Figure 1 The diagram shows five workstations 190, each equipped with an energy storage component 110. Specifically, each workstation 190 includes a battery pack 111, a liquid cooling plate 112, a first insulation component 113, a second insulation component 114, and a third insulation component 115. Each workstation 190 prevents condensation and achieves the aforementioned beneficial effects, which will not be elaborated upon further.

[0046] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
