Technical Field

[0001] This utility model relates to the field of energy storage technology, and in particular to a dehumidifier and an energy storage cabinet. Background Technology

[0002] In existing technologies, the battery packs inside energy storage cabinets are generally cooled by liquid cooling. Liquid cooling has the advantages of high efficiency and high energy density, but liquid cooling units usually do not have active dehumidification function, and a large amount of condensate will exist inside the energy storage cabinet.

[0003] In the process of realizing this invention, the inventors discovered that the prior art has at least the following problems: In order to solve the dehumidification problem of liquid cooling units, the prior art usually sets up a dehumidifier in the system. However, the overall structure of the dehumidifier is complex, and it requires the setting of a matching control circuit. Moreover, the dehumidifier needs to use refrigeration components such as compressors and semiconductor chips, which will increase the overall volume of the dehumidifier. This will occupy a large space inside the energy storage cabinet, making the internal space of the energy storage cabinet even more congested.

[0004] Therefore, how to provide an energy storage cabinet that can at least partially solve the above problems is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this utility model is to provide an energy storage cabinet, which is equipped with a dehumidifier that can dehumidify the air. The dehumidifier has a simple structure, does not require a matching control circuit, and does not require a compressor, semiconductor chip or other refrigeration components inside. This makes the overall size of the dehumidifier small and does not occupy a large space inside the energy storage cabinet.

[0008] The cabinet includes a battery pack housing cavity, and an airflow channel for air circulation is provided inside the battery pack housing cavity.

[0009] The dehumidifier is connected to the inner wall of the battery pack housing cavity and is located in the air flow channel. The dehumidifier can be used to connect to the cooling medium circulation pipeline of the heat exchange system to condense and dehumidify the air in the air flow channel.

[0010] In one possible design, the dehumidifier includes: a housing, an air inlet on the side wall of the housing, an air outlet on the top of the housing, a drain outlet at the bottom of the housing and connected to the outside, and a condensation module inside the housing. The condensation module is located between the air inlet and the air outlet and is used to condense and dehumidify the passing air. A fan is provided at the air outlet to drive the air through the air inlet, dehumidify it through the condensation module, and then discharge it through the air outlet. The condensate produced by the condensation module on the passing air is discharged through the drain outlet.

[0011] In one possible design, the condensing module includes a support plate, support uprights connected to both sides of the support plate, and fins disposed between the two support uprights. A refrigerant coil with a bent structure is inserted through the middle of the fins. The fins abut against the support uprights and the support plate to form a condensing cavity. The condensing cavity is covered by the air inlet so that all air entering the housing passes through the fins.

[0012] In one possible design, the housing includes a main housing and a back panel. The main housing and the back panel are mated to form a cavity for installing the condenser module. The cavity is connected to the air inlet and the air outlet, respectively. Connecting ears are provided at the edge of the back panel for connecting the dehumidifier to the cabinet.

[0013] In one possible design, the main housing is a square housing with an opening on one side, the air inlet is located on the first plate of the main housing, the air outlet is located on the second plate of the main housing, and the drain outlet is located on the third plate of the main housing.

[0014] The first plate is equipped with two sets of air outlets and corresponding fans, and the fans are connected to the inner wall of the second plate.

[0015] The fourth plate of the main housing is provided with a cable interface for the fan cable.

[0016] In one possible design, the two ends of the refrigerant coil are located on the same side of the fins, and each end is welded with a plug. The plug is used to connect the cooling medium circulation pipeline of the heat exchange system. The fourth plate is provided with a first U-shaped groove for accommodating the plug.

[0017] The back panel includes a vertical plate that abuts against the fourth plate. The vertical plate is provided with a second U-shaped groove that mates with the first U-shaped groove. The first U-shaped groove and the second U-shaped groove mate to fix the plug connector.

[0018] In one possible design, the fins and the support plate are both connected to the first plate at an angle, and the support plate has a first through hole at its lowest point relative to the third plate to connect the condensation cavity and the drain outlet.

[0019] A sealing ring is laid between the condenser module and the first plate;

[0020] The edge of the third plate is filled with sealant to prevent leakage of condensate generated by the condensation module.

[0021] The air inlet is located at the end of the first plate near the third plate, and the air inlet has a honeycomb structure.

[0022] This application also provides a dehumidifier, including: a housing, an air inlet disposed on the side wall of the housing, an air outlet disposed on the top of the housing, a drain outlet disposed on the bottom of the housing and communicating with the outside, and a condensation module disposed inside the housing. The condensation module is located between the air inlet and the air outlet. The condensation module is used to condense and dehumidify the passing air. A fan is provided at the air outlet. The fan is used to drive the air through the air inlet to enter, be dehumidified by the condensation module, and then be discharged from the air outlet. The condensate generated by the condensation module on the passing air is discharged through the drain outlet.

[0023] In one possible design, the condensing module includes a support plate, support uprights connected to both sides of the support plate, and fins disposed between the two support uprights. A refrigerant coil with a bent structure is inserted through the middle of the fins. The fins abut against the support uprights and the support plate to form a condensing cavity. The condensing cavity is covered by the air inlet so that all air entering the housing passes through the fins.

[0024] The two ends of the refrigerant coil are located on the same side of the fins, and each end is welded with a plug connector, which is used to connect the cooling medium circulation pipeline of the heat exchange system.

[0025] In one possible design, the support plate is provided with a first through hole to connect the condensation cavity and the drain outlet.

[0026] Compared with the prior art, the energy storage cabinet provided in this application has at least the following technical effects:

[0027] The cabinet contains a battery pack housing cavity, which houses the battery packs. An airflow channel is the space within the battery pack housing cavity where no battery packs are placed, allowing for air circulation. To dehumidify the air inside the cabinet, a dehumidifier is installed on the inner wall of the battery pack housing cavity, located within the airflow channel. Furthermore, this dehumidifier can be directly connected to the cooling medium circulation pipeline of the heat exchange system. The low-temperature medium transported through the cooling medium circulation pipeline liquefies the moisture in the air within the airflow channel, thus achieving dehumidification. In this way, dehumidification of the energy storage cabinet can be completed solely through the cooling medium circulation pipeline of the heat exchange system, eliminating the need for complex control circuits and internal compressors, semiconductor chips, or other refrigeration components. This results in a smaller overall size and makes installation and maintenance simple and convenient. Attached Figure Description

Detailed Implementation

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left" and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.

[0044] The purpose of this utility model is to provide an energy storage cabinet, which is equipped with a dehumidifier that can dehumidify the air. The dehumidifier has a simple structure, does not require a matching control circuit, and does not require a compressor, semiconductor chip or other refrigeration components inside. This makes the overall size of the dehumidifier small and does not occupy a large space inside the energy storage cabinet.

[0045] To achieve the above objectives, the present invention provides the following technical solution:

[0046] Please see Figure 1 This embodiment provides an energy storage cabinet, including: a cabinet body 100 and a dehumidifier 200; the cabinet body 100 includes a battery pack receiving cavity, and an air flow channel for air flow is provided inside the battery pack receiving cavity; the dehumidifier 200 is connected to the inner wall of the battery pack receiving cavity and is located inside the air flow channel. The dehumidifier 200 can be used to connect to the cooling medium circulation pipeline of the heat exchange system to condense and dehumidify the air in the air flow channel.

[0047] In this embodiment, the upper part of the cabinet 100 is provided with a battery pack receiving cavity for placing battery packs. Multiple battery packs can be placed inside the battery pack receiving cavity from top to bottom. In order to facilitate the placement of battery packs, the distance between each two adjacent layers is greater than the thickness of the battery pack. That is to say, when the battery packs are completely placed in the battery pack receiving cavity, there will be gaps between each two adjacent layers of battery packs. It should be noted that after the battery packs in this embodiment are placed, there will be gaps between them and the inner wall of the cabinet 100. These gaps will connect with the gaps between the battery pack layers to form airflow channels.

[0048] Air inside the cabinet 100 circulates continuously within the airflow channel. In this embodiment, the dehumidifier 200 is detachably installed on the inner wall of the cabinet 100 and located within the airflow channel. The dehumidifier 200 utilizes the heat exchange system arranged in the lower layer of the energy storage cabinet to dehumidify the air within the airflow channel. Specifically, the dehumidifier 200 is connected to the cooling medium circulation pipeline of the heat exchange system. It does not require a compressor, semiconductor chip, or other refrigeration components inside, nor does it require complex control circuits to control its operation. The dehumidifier 200 is supplied with a low-temperature refrigerant through the refrigerant pipe of the heat exchange system, maintaining a low internal temperature. This causes the moisture in the air passing through the dehumidifier 200 to condense into water droplets upon cooling, thus maintaining dehumidification and ensuring the air remains dry.

[0049] Furthermore, in this embodiment, to ensure convenient installation and maintenance of the dehumidifier 200, the dehumidifier 200 is hung on the inner wall of the cabinet door of the cabinet 100. In this way, when the cabinet door is closed, the dehumidifier 200 can be located in the air flow channel to dehumidify the air flowing through it. When the cabinet door is open to install the battery pack or to maintain the battery pack, the dehumidifier 200 will not occupy the space of the battery pack cavity. This allows the overall structure of the energy storage cabinet to be more compact and improves the utilization rate of the internal space of the cabinet 100.

[0050] Of course, the dehumidifier 200 can also be installed in other locations according to the actual layout inside the energy storage cabinet, as long as it can ensure dehumidification of the battery pack cavity. This embodiment only provides one preferred installation location.

[0051] Furthermore, in this embodiment, the cooling medium introduced into the dehumidifier 200 can be cooling water or other refrigerants, as long as the low temperature inside the dehumidifier 200 can be maintained to complete the dehumidification of the air. This article does not make any specific limitations.

[0052] In some embodiments, a dehumidifier 200 is provided, which can be applied to the energy storage cabinet of the above embodiments. The dehumidifier 200 includes: a shell, an air inlet 210 disposed on the side wall of the shell, an air outlet 220 disposed on the top of the shell, a drain outlet 230 disposed on the bottom of the shell and communicating with the outside, and a condensation module 240 disposed inside the shell. The condensation module 240 is located between the air inlet 210 and the air outlet 220. The condensation module 240 is used to condense and dehumidify the passing air. The air outlet 220 is provided with a fan 221. The fan 221 is used to drive the air through the air inlet 210 to enter the condensation module 240 for dehumidification and then discharge it from the air outlet 220. The condensate generated by the condensation module 240 condensing the passing air is discharged through the drain outlet 230.

[0053] Specifically, such as Figure 2 and Figure 3 As shown, the dehumidifier 200 is installed on the inner wall of the cabinet door of the cabinet 100. An air inlet 210 is located on the side near the battery pack, and an air outlet 220 is located on the top of the dehumidifier 200. To ensure air circulation, a fan 221 is installed at the air outlet 220 to draw air from the air inlet 210 into the housing of the dehumidifier 200. Because a condenser module 240 is installed inside the housing between the air inlet 210 and the air outlet 220, all air entering the housing must pass through the condenser module 240. The condenser module 240 interacts with the cooling medium of the heat exchange system. The circulating pipeline is connected, and the low-temperature cooling medium transported through the circulating pipeline keeps the condenser module 240 at a low temperature. Moisture in the air passing through the condenser module 240 is cooled and condensed into liquid water droplets, which fall to the bottom of the housing and are discharged to the outside through the drain outlet 230 at the bottom of the housing. Thus, under the action of the fan 221, air in the airflow channel is constantly drawn in through the air inlet 210 of the dehumidifier 200, dehumidified by the condenser module 240, and discharged through the air outlet 220 at the top. This creates a continuous circulation of air in the airflow channel. Figure 1 As shown, the airflow channels are distributed along the battery pack. Under the action of the dehumidifier 200, the air in the airflow channels will continuously flow clockwise and pass through the dehumidifier 200. With the support of the fan 221, it will continue to flow clockwise until it passes through the dehumidifier 200 again. In this way, the dryness of the air inside the cabinet 100 can be guaranteed to the greatest extent, thus ensuring the dehumidification effect.

[0054] In one possible design, the condensing module 240 includes a support plate 241, support uprights 242 connected to both sides of the support plate 241, and fins 243 disposed between the two support uprights 242. A refrigerant coil 244 with a bent structure is inserted through the middle of the fins 243. The fins 243 abut against the support uprights 242 and the support plate 241 respectively to form a condensing cavity 245. The condensing cavity 245 covers the air inlet 210 so that all the air entering the housing passes through the fins 243.

[0055] Specifically, such as Figure 4 and Figure 5 As shown, two identical support plates 242 are installed on both sides of a support plate 241. Between the two support plates 242, several vertical fins 243 are installed. A refrigerant coil 244 with a tortuous structure is inserted through the middle of these fins 243. The refrigerant coil 244 is connected to the cooling medium circulation pipeline of the heat exchange system. When the low-temperature refrigerant passes through the fins 243, the fins 243 will be cooled down significantly. As the air passes through the fins 243, the moisture attached to it will condense into water droplets and flow down the fins 243 to the bottom of the shell.

[0056] Furthermore, to ensure the dehumidifier 200's effectiveness, that is, to ensure that all air entering the dehumidifier 200 passes through the condenser module 240, the condenser module 240 is designed as a cover. In this embodiment, the two supporting plates 242 are similar to a triangular structure, with the left and right sides of the fins 243 abutting against the supporting plates 242, and the lower edge of the fins 243 abutting against the supporting plate 241. This forms a triangular prism-like structure with an opening on one side. When installing the condenser module 240, the open side of the condenser module 240 completely covers the air inlet 210, specifically as follows... Figure 6 As shown, in this way, the air entering from the air inlet 210 will be condensed and liquefied by the fins 243.

[0057] In one possible design, the housing includes a main housing 250 and a back plate 260. The main housing 250 and the back plate 260 are mated to form a cavity for installing the condenser module 240. The cavity is connected to the air inlet 210 and the air outlet 220 respectively. A connecting ear 261 is provided at the edge of the back plate 260 for connecting the dehumidifier 200 to the cabinet 100.

[0058] Specifically, such as Figure 7 and Figure 8As shown, the housing includes two parts: a main housing 250 and a back plate 260, both of which are made of sheet metal. The main housing 250 and the back plate 260 are connected by screws after being joined together. The main housing 250 and the back plate 260 can form a cavity after being joined together. The condensing module 240 is installed inside the cavity and divides the cavity into two parts. One part is the condensing cavity 245 inside the condensing module 240, where the air that has not been dehumidified by liquid cooling by the fins 243 is located. The other part is the space other than the condensing cavity 245, where the air that has been dehumidified by the fins 243 will enter and then be discharged from the air outlet 220 under the action of the fan 221.

[0059] In addition, in this embodiment, connecting ears 261 are provided at the upper and lower edges of the back panel 260, and screw holes are provided on the connecting ears 261, so that the dehumidifier 200 can be easily installed on the inner wall of the cabinet 100.

[0060] In one possible design, the main housing 250 is a square housing with an opening on one side. The air inlet 210 is located on the first plate 251 of the main housing 250, which is the plate opposite to the opening. The air outlet 220 is located on the second plate 252 of the main housing 250, which is the plate adjacent to and above the first plate 251. The drain outlet 230 is located on the third plate 253 of the main housing 250, which is the plate opposite to the second plate 252. It should be noted that the main housing 250 is a one-piece structure, formed by bending a single cross-shaped plate. The second plate 252, the third plate... There is no gap between plate 253 and the first plate 251; the first plate 251 is provided with two sets of air outlets 220 and a fan 221 corresponding to the air outlets 220. The fan 221 is connected to the inner wall of the second plate 252. The fan 221 can accelerate the air circulation in the air channel, thereby achieving a better dehumidification effect; it is understandable that the fourth plate 254 of the main housing 250, which is one side of the first plate 251, is provided with a wire passage interface 255 for the fan 221 to pass through. The wire passage interface 255 can be provided with a sealing sleeve to prevent air from entering the housing from the wire passage interface 255.

[0061] In one possible design, both ends of the refrigerant coil 244 are located on the same side of the fins 243, and each end is welded with a connector 246. The connector 246 is used to connect to the cooling medium circulation pipeline of the heat exchange system. It is understood that in this embodiment, the dehumidifier 200 is installed on the inner wall of the cabinet door of the cabinet 100. To ensure smooth opening and closing of the cabinet door, the inlet and outlet of the refrigerant coil 244 are located on the side near the rotating shaft of the cabinet door. Furthermore, in this embodiment, the two ports of the refrigerant coil 244 can be selected as inlets or outlets according to actual needs, as long as the smooth flow of the refrigerant medium is ensured. Moreover, to facilitate the connection between the refrigerant coil 244 and the cooling medium circulation pipeline of the heat exchange system, connectors 246 are installed at its ports, specifically as follows... Figure 9 As shown, the smaller diameter end of the connector 246 is welded to the end of the refrigerant coil 244, while the larger diameter end can be directly snapped into the cooling medium circulation pipeline of the heat exchange system, thus improving the installation convenience of the dehumidifier 200.

[0062] Understandably, in order to fix the connectors 246 at both ends of the refrigerant coil 244, a first U-shaped groove 256 for accommodating the connectors 246 is provided on the fourth plate 254. Correspondingly, a vertical plate 262 that can abut against the fourth plate 254 is also provided on one side of the back plate 260. A second U-shaped groove 263 is provided on the vertical plate 262 at the position corresponding to the first U-shaped groove 256. After the back plate 260 and the main housing 250 are installed, the first U-shaped groove 256 will mate with the second U-shaped groove 263 to fix the connectors 246.

[0063] In one possible design, both the fins 243 and the support plate 241 are connected to the first plate 251 at an angle. This arrangement not only ensures that the air entering the condensation cavity 245 can pass vertically through the fins 243 to ensure the condensation effect, but also allows the condensate generated by condensation to slide downwards along the support plate 241. At the same time, a first through hole 247 is provided at the lowest point of the support plate 241 relative to the third plate 253 to connect the condensation cavity 245 and the drain outlet 230. In this way, the condensate generated by the condensation of moisture in the air by the fins 243 will slide downwards along the support plate 241, enter the bottom of the shell through the first through hole 247, and then flow out from the drain outlet 230.

[0064] In this embodiment, to ensure that all incoming air passes through the condensation module 240, a sealing ring 270 is laid between the condensation module 240 and the first plate 251. This ensures that there is no leakage between the condensation cavity 245 and the cavity inside the housing. Furthermore, to prevent condensate at the bottom of the housing from leaking out of the dehumidifier 200, the edge of the third plate 253 is filled with sealant. In addition, the air inlet 210 in this embodiment is located at the end of the first plate 251 near the third plate 253, which makes it easier for air to enter the housing and ensures dehumidification efficiency. Moreover, the air inlet 210 in this embodiment has a honeycomb structure composed of several hexagonal holes, which maximizes the amount of air entering and prevents parts or wires from being sucked into the dehumidifier 200.

[0065] This application also provides a dehumidifier 200, which can be applied to the energy storage cabinet of any of the above embodiments, but is not limited to. The dehumidifier 200 includes: a shell, an air inlet 210 disposed on the side wall of the shell, an air outlet 220 disposed on the top of the shell, a drain outlet 230 disposed on the bottom of the shell and communicating with the outside, and a condenser module 240 disposed inside the shell. The condenser module 240 is located between the air inlet 210 and the air outlet 220. The condenser module 240 can be connected to the cooling medium circulation pipeline of the heat exchange system, and the cooling medium is transported through the cooling medium circulation pipeline. The low-temperature refrigerant medium ensures that it can condense and dehumidify the air passing through it. The air outlet 220 of the dehumidifier 200 is equipped with a fan 221. The fan 221 can continuously draw air in from the air inlet 210. Then the air will pass through the condensation module 240, where the moisture in the air will liquefy into condensate and drip to the bottom of the shell, and be discharged to the outside through the drain 230. At the same time, after being dehumidified by the condensation module 240, it will be discharged from the air outlet 220 and then discharged again. In this way, the air in the space where the dehumidifier 200 is located can be condensed and dehumidified.

[0066] In one possible design, the condenser module 240 includes a support plate 241, support plates 242 connected to both sides of the support plate 241, and fins 243 disposed between the two support plates 242. A refrigerant coil 244 with a bent structure is inserted through the middle of the fins 243. The fins 243 abut against the support plates 242 and 241 respectively to form a condensation cavity 245. The condensation cavity 245 covers the air inlet 210. In this way, it can be ensured that the air entering the dehumidifier 200 will pass through the fins 243 evenly, thus ensuring the dehumidification effect of the dehumidifier 200.

[0067] It should be noted that the shape of the housing can be adjusted according to the actual situation, but it is necessary to ensure that all the air entering the housing can be dehumidified by the condensation module 240, and that the generated condensate can be discharged smoothly.

[0068] In one possible design, the support plate 241 is provided with a first through hole 247 to connect the condensation cavity 245 and the drain port 230. Understandably, this arrangement can ensure that the condensate generated by the fins 243 can be smoothly discharged into the bottom of the shell and drained out, without causing excessive accumulation of condensate and discharge from the air inlet 210.

[0069] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0070] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0071] The embodiments provided by this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
