Air supply assembly, air supply mechanism and energy storage device

Abstract

This application relates to the field of energy storage devices, providing an air supply component, an air supply mechanism, and an energy storage device. According to the air supply component provided in this application, an air inlet and an air outlet are spaced apart on the base, meaning that gas is released from the air inlet and flows back to the air outlet. Based on this, the air supply component provided in the embodiments of this application releases airflow into the space through the air inlet; that is, the air inlet's air intake method is an open air intake. Conversely, the air guide component has a first opening communicating with the air outlet and uses a second opening to collect gas in the space, thus constructing a relatively closed return air structure connected to the air outlet using the air guide component. The airflow delivered through the air inlet can travel a shorter path to reach the return air outlet, reducing airflow resistance and improving the heat exchange effect. This solves, to some extent, the technical problem that the presence of a delivery pipeline results in fixed pipeline resistance, airflow performance loss, and reduced heat exchange effect.

Description

Technical Field

[0001] This application relates to the field of energy storage equipment, and in particular to an air supply component, an air supply mechanism, and an energy storage device. Background Technology

[0002] Air-cooled systems are easy to install and safe and reliable, making them the primary temperature control method in the current energy storage equipment field. Air cooling, which uses air as the cooling medium and utilizes convection heat transfer to reduce battery temperature, is widely used in various fields and has relatively high technological maturity and reliability.

[0003] However, due to the low specific heat capacity and thermal conductivity of air, the heat dissipation efficiency of air-cooled systems is not high. In the air-cooled ducts of energy storage devices, air generated by refrigeration equipment such as air conditioners, such as cold air, is often transported to designated locations of heat-generating devices such as batteries through pipelines. Then, the gas is directed to the return air vent through a closed pipeline connected to the delivery pipeline, or an open return air vent is used to achieve return air.

[0004] However, in practical applications, the presence of the delivery pipeline results in a fixed pipeline resistance for the airflow, leading to performance loss and reduced heat exchange efficiency. Utility Model Content

[0032] According to a first aspect of the embodiments of this application, an air supply assembly 700 is provided, which will be described below in conjunction with... Figures 1 to 4 The structure and working principle of the air supply component 700 are described in detail.

[0033] According to the embodiments of this application, the air supply assembly 700 includes a base 100 and an air guide assembly 200.

[0034] In this embodiment, the base 100 has an air inlet and an air outlet 110 spaced apart, with the air inlet releasing airflow into the space. The air guide assembly 200 has a first opening 211 and a second opening 221 that are connected, with the first opening 211 connected to the air outlet 110 and the second opening 221 collecting gas from the space.

[0035] Thus, according to the air supply assembly 700 provided in the embodiments of this application, an air inlet and an air outlet 110 are provided at intervals on the base 100. That is, gas is released from the air inlet and flows back to the air outlet 110. Based on this, the air supply assembly 700 provided in the embodiments of this application releases airflow into the space through the air inlet, that is, the air inlet is an open air intake method; in contrast, the air guide assembly 200 has a first opening 211 communicating with the air outlet 110, and uses a second opening 221 to collect the gas in the space, so that the air guide assembly 200 constructs a relatively closed return air structure communicating with the air outlet 110.

[0036] Therefore, the air supply component 700 provided according to the embodiments of this application adopts an open air inlet and a closed air return outlet, so that the airflow supplied from the air inlet can travel a shorter path to the second opening 221 relative to the flow path of the set entity, and then reach the air return outlet, thereby reducing the airflow resistance and improving the heat exchange effect of the airflow, such as the cooling or heating effect.

[0037] In this embodiment, the air supply component 700 can release cold air below room temperature (where room temperature can be understood as normal room temperature or the ambient temperature of the air supply component 700 as a whole) into the space through the air inlet, or it can release hot air above room temperature into the space, as needed.

[0038] It should be noted that the above-mentioned "release into space" means that the airflow in the air inlet diffuses into space and is not guided by physical pipes, but it does not mean that the airflow is not guided at all. In fact, even if the airflow diffuses into space, it can be guided by means of deflectors or covers.

[0039] In the embodiment, the aforementioned "space" may be, for example, the space facing one side of the base 100. A target structure may be set in this space. Depending on the target structure, the delivered air may be cold or hot. For example, if the target structure generates heat higher than the aforementioned normal temperature, and there is a need for cooling, cold air may be released into the space to exchange heat with the target structure. Conversely, if the target structure needs to be heated, hot air may be released into the space to exchange heat with the target structure to heat the target structure.

[0040] As an example, in an embodiment, the target structure may be, for example, an electrical structure that generates its own heat, such as an energy storage device that needs to be charged and discharged, such as an energy storage battery.

[0041] In practical applications, the air supply component 700 can be used primarily for cooling purposes, and the return air vent can be arranged above the air inlet. By utilizing the characteristic of hot air moving upwards, the second opening 221 can collect the airflow in the space more effectively.

[0042] Furthermore, in the embodiments, the base 100 may be, for example, a plate-like structure, such as a rectangular plate-like structure, and may serve as part of a cabinet forming the storage of the target structure, such as part of an energy storage cabinet in an energy storage device. The ability of the second opening 221 to recover airflow can be achieved by an air supply structure disposed on the side of the base 100 opposite to the aforementioned space, such as an air conditioner.

[0043] According to the air supply assembly 700 provided in the embodiments of this application, as described above, a cover can be used to guide the airflow released into the space. In the embodiments, the cover is a physical housing 300, which can be installed outside the air outlet 110. The housing 300 has an air outlet 311 that connects the interior of the housing 300 with the exterior of the housing 300.

[0044] Thus, according to the air supply assembly 700 provided in the embodiments of this application, the airflow released from the air inlet into the space is guided to a certain extent by the housing 300 and the air outlet 311 on the housing 300, and the airflow direction is adjusted by the air outlet 311.

[0045] As an example, the housing 300 can be connected to the base 100, for instance, the housing 300 can be detachably connected to the base 100 (e.g., by screws). On the one hand, the housing 300 and the base 100 are integrated into a module, facilitating their overall installation and transportation. Furthermore, when installed on a cabinet body 500 such as an energy storage device, the base 100, as a plate-like structure, can also form a hinged or other movable connection with the energy storage device, thereby enabling the energy storage device to be opened by the rotational movement of the base 100, and the housing 300 to move together with the base 100, facilitating the disassembly and maintenance of the housing 300.

[0046] In an embodiment, the housing 300 may include a plurality of sides 310, each of which at least a portion thereof is provided with an air outlet 311. This facilitates the full dispersion of airflow through the enclosure of the housing 300, especially since each of the plurality of sides 310 is provided with an air outlet 311 to achieve uniform release of airflow into space.

[0047] In this embodiment, as an example, the housing 300 can be, for example, a cuboid open-top housing 300, with the open-top side snapped onto the outside of the air outlet 110, and the other five sides 310 can each be provided with an air outlet 311. The air outlet 311 can be, for example, a through hole, and as an example, it can be, for example, a rectangular through hole.

[0048] According to the air supply assembly 700 provided in the embodiments of this application, the air supply assembly 700 may further include a heat insulation component, which may be disposed inside the housing 300 and may be disposed around the edge of the air outlet 311. For example, the heat insulation component may be a strip of polyurethane, which may be attached to the edge of the air outlet 311 inside the housing 300.

[0049] In the embodiment, the housing 300 may be made of metal, such as sheet metal, which is easy to mass-produce. When dealing with cold air released from the air inlet, the cold air blowing directly onto the sheet metal may cause condensation to form on the sheet metal. In the case of electrical structures in the target structure within the space, condensation may be detrimental. Therefore, the insulation component here avoids the cold air blowing directly around the air outlet 311, thereby reducing the risk of condensation.

[0050] According to the air supply assembly 700 provided in the embodiments of this application, the air supply assembly 700 may further include a cover member 230, which covers the outside of the air outlet 110, and the side where the first opening 211 of the air guide assembly 200 is located may abut against the cover member 230.

[0051] In this embodiment, the cover member 230 is used to connect the first opening 211 and the air outlet 110. As an example, the cover member 230 can be connected to the base 100 in a detachable connection manner similar to that described above, that is, the cover member 230 can also move with the base 100.

[0052] In this embodiment, the air guide assembly 200 can be positioned within the space described above. The air guide assembly 200 abuts against the cover member 230 because the connection between the first opening 211 and the air outlet 110 is established only when the base 100 is in a certain position, such as a closed cabinet position. In other words, the air guide assembly 200 may not move with the base 100. Thus, when maintenance is required on an air supply structure such as an air conditioner installed on the base 100, the base 100 is rotated relative to the cabinet, and the cover member 230 and the housing 300 on the cabinet move independently with the base 100, while the relatively complex air guide assembly 200 remains in the space, which is particularly convenient for individual maintenance operations on the air conditioner.

[0053] According to the air supply assembly 700 provided in the embodiments of this application, the air guiding assembly 200 may include an air duct component 220 and a transition component 210. In the embodiments, the air duct component 220 may have a second opening 221. Specifically, the air duct component 220 may be, for example, a tubular structure, and may be generally cuboid in shape with an internal channel having a rectangular cross-section.

[0054] In an embodiment, the transition member 210 may be connected to the duct member 220 (e.g., using a detachable connection such as a bolted connection as described above), the transition member 210 may have the first opening 211 as described above, and the transition member 210 may also have a duct cavity for connecting the second opening 221 and the first opening 211.

[0055] In this embodiment, the cross-sectional area of ​​the air cavity gradually decreases from the side where the second opening 221 is located to the side where the first opening 211 is located. That is, the area of ​​the air cavity gradually decreases from the upstream side to the downstream side of the gas flow direction inside the air guide assembly 200. In this way, the large air pressure caused by the sudden change from the relatively large cross-sectional area of ​​the air duct to the cross-sectional area of ​​the air outlet 110 is reduced, thereby ensuring that the performance of the air conditioner is fully utilized.

[0056] In the embodiments, the transition member 210 can actually be, for example, a T-shaped structure, or an approximately T-shaped structure. Specifically, the transition member 210 can have two parts. One part is used to connect with the air duct, and this part can have the air cavity as described above. This part can generally present a hollow frustum-shaped trumpet structure to achieve the purpose of gradually reducing the cross-sectional area of ​​the air cavity. The other part of the transition member 210 can be, for example, a shorter cuboid air duct structure as described above, located between the air outlet 110 and the aforementioned part of the transition member 210.

[0057] According to the air supply assembly 700 provided in the embodiments of this application, the air guide assembly 200 may have multiple air duct components 220, that is, the air guide assembly 200 includes multiple air duct components 220, each air duct component 220 has a second opening 221, each air duct component 220 has an extending direction, which is the direction in which the gas actually flows within the air duct component 220, and the aforementioned multiple air duct components 220 may be arranged along a direction intersecting the extending direction, for example, along a direction perpendicular to the extending direction.

[0058] In this embodiment, each duct component 220 has a duct that allows gas to flow through it. The ducts of adjacent duct components 220 are interconnected, thereby balancing the air pressure within the ducts of adjacent duct components 220. Specifically, a connecting portion 400 may be provided between adjacent ducts to connect them. The connecting portion 400 may be substantially, for example, a tubular structure. Here, the connecting portion 400 may be used to detachably connect adjacent duct components 220 by means such as bolts.

[0059] In the embodiment, the arrangement of the above-mentioned multiple air duct components 220 is beneficial to enable each air duct component 220 to undertake the airflow recovery work of the corresponding area in the space, so as to make the return air more uniform.

[0060] The air supply assembly 700 provided in this application embodiment has an open air outlet 110 and a closed return air outlet, allowing the air conditioning cool air to travel a shorter path directly to the heat source of the target structure such as a battery, thus helping to improve the cooling effect and reducing the airflow resistance pressure. Furthermore, based on the differences in heat generation in different areas of the battery, through simulation, the air outlet 311 can be positioned at a corresponding location on the housing 300 according to the simulation results, so that the airflow distribution meets the actual application requirements.

[0061] According to the air supply component 700 provided in the embodiments of this application, in addition, compared with the air inlet sealing scheme in the prior art, the return air inlet sealing can effectively reduce the risk of condensation inside the air duct.

[0062] In this embodiment, the airflow is adjusted by changing the direction of the air conditioner's airflow through the housing 300, which serves as an open hood, outside the air outlet 110. Based on the heat distribution of the battery, the hood has openings on the left, right, top, bottom, and front to distribute the airflow as needed and to control the temperature difference of the entire battery cluster reasonably.

[0063] In addition, the air guide assembly 200 has low wind resistance (approximately 0.2 kg / s @ 172 Pa) and minimal air conditioning performance loss. Using this air duct, the temperature difference in the battery compartment of the energy storage device can be controlled at around 8°C, allowing the battery to complete the required charging and discharging operations, and the heat can be promptly removed by the air conditioner.

[0064] According to a second aspect of the embodiments of this application, an air supply mechanism is provided. The air supply mechanism includes the air supply component 700 as described above. The air supply mechanism also includes an air supply structure, which includes an air supply port and a return air port. The air supply port is connected to an air inlet, and the return air port is connected to an air outlet 110. Here, the air supply structure can be, for example, an air conditioner as described above, that is, the air supply structure can both cool and heat, such as providing cold air to the battery cluster to cool it down in summer and providing hot air to the battery cluster to keep it warm in winter.

[0065] In addition, in some other examples not shown, the air supply structure may provide only hot air or only cold air.

[0066] In this embodiment, the air return vents of the air conditioner can be distributed on the left and right sides of the top of the air conditioning compartment. Heat accumulates in this area, and the suction force of the air return vents is transferred to this area through the closed air return vents, so as to realize the timely recovery of the heat generated by the battery.

[0067] A third aspect of the embodiments of this application provides an energy storage device, which includes the air supply assembly 700 as described above, or includes the air supply mechanism as described above. In the embodiments, the energy storage device may be, for example, an energy storage cabinet, with a battery compartment below and an electrical compartment above, and the base 100 as described above may serve as the rear wall of the battery compartment. Multiple battery clusters may be arranged side by side in the battery compartment. As an example, two battery clusters are shown in the figure, but it is not limited to this. There may be more battery clusters, such as three, four, or five, or only one battery cluster may be provided. Here, as an example, the battery cluster may include lithium batteries.

[0068] According to the energy storage device provided in the embodiments of this application, the energy storage device may include a cabinet body 500, and a base 100 as described above, which is movably connected to the cabinet body 500 in a manner such as hinged, so as to be able to close and open the cabinet body 500. The cabinet body 500 is provided with the aforementioned multiple sets of battery clusters. In the embodiments, the number of air duct components 220 of the air guide assembly 200 is the same as the number of battery clusters, and each air duct component 220 can be disposed above the corresponding battery cluster, thereby recovering the hot airflow at the location of the corresponding battery cluster.

[0069] In the embodiment, each energy storage component 600, that is, each battery cluster, has multiple battery packs. The battery pack itself can have an air inlet path and an air outlet path. In other words, the battery pack can be an existing battery pack with its own air inlet, air outlet, and internal air cooling. Its air inlet path can be located on the side 310 facing the base 100 of the energy storage component 600. That is, the air supply component 700 is suitable for the air inlet and outlet structure of the battery pack with air inlet at the back and air outlet at the front. The air inlet (cold air) of the air supply component 700 is close to the air inlet structure on the back side of the battery pack, and the air outlet 110 (hot air) is close to the air outlet structure of the battery pack. Together with the battery's own cooling fan and the gap between battery layers, a complete air supply circuit is formed.

[0070] In this embodiment, the air supply mechanism allows the air-cooled air conditioner to be installed at the back of the battery compartment, saving the opening and maintenance space required on the front of the energy storage cabinet. As mentioned above, the cabinet can be designed with an upper and lower structure (electrical compartment on top and battery compartment on the bottom) to save space in the width direction.

[0071] The above are merely preferred embodiments of this application and do not limit the scope of protection of this application. Any equivalent structural transformations made based on the innovative concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
