Description

Technical Field

[0001] The utility model relates to the technical field of air-cooled energy storage, and particularly relates to an air distribution device for an air-cooled energy storage system and an air-cooled energy storage system. Background Art

[0002] In the prior art, the air conditioner of the air-cooled cabinet is installed on the front door and adopts front air supply. Then, through the internal air duct, it is transmitted to the module PACK by means of rear air inlet and side air inlet, resulting in uneven air inlet between the PACK layers. Installing the air conditioner on the front door of the air-cooled cabinet has a great impact on the appearance and also generates relatively high noise. The intermediate transmission method does not effectively divide the air evenly. In addition, there is a top-mounted air conditioner with a direct cooling air distribution method, which has a complex air distribution structure, high air duct cost, and large air volume loss in the system due to the use of a sheet metal box for air distribution.

[0022] Embodiment 1

[0023] As Figure 1 - Figure 2As shown in the figure, a air distribution device for an air-cooled energy storage system includes a static pressure box 1 (the static pressure box 1 can convert part of the dynamic pressure into static pressure to make the wind blow farther, provide the same wind pressure, control the wind pressure, and evenly distribute the air volume) and four air distribution pipelines 3. A duct 2 is arranged on the upper surface of the static pressure box 1. The duct 2 is used to connect the air inlet of the static pressure box 1 with the air outlet of the air conditioner. The air outlet of the static pressure box 1 is connected to the air inlet of the air distribution pipeline 3. The static pressure box 1 is connected to the PACK air inlet through the air distribution pipeline 3. The air distribution pipeline 3 is arranged on the side wall of the static pressure box 1. Two air distribution pipelines 3 are respectively arranged on two adjacent side walls (or two opposite side walls) of the static pressure box 1; the air distribution pipelines 3 are all bent at 90°. The air outlet port 5 of the air distribution pipeline 3 is connected to the air inlet of the PACK. An adjustable air valve 4 is installed on each air distribution pipeline 3 to control the air volume. The distances of the four air valves 4 from the air inlet of the air distribution pipeline 3 are different or the same. In this embodiment, the air valve 4 is an electric air valve 4. The four air distribution pipelines 3 provide the same or differentially adjustable air volume requirements, so that the air volume and wind pressure errors at the air outlet are only 2%. The air distribution pipeline 3 is a standard flat pipe.

[0024] Specifically, the materials of the air distribution pipeline 3 and the static pressure box 1 are made of heat-insulating materials.

[0025] Embodiment 2

[0026] This embodiment provides an air-cooled energy storage system. The system includes an energy storage cabinet, an air-conditioning air-cooling system, and the air distribution device described in Embodiment 1. The air-conditioning air-cooling system is installed on the energy storage cabinet. The air-conditioning air-cooling system is connected to the PACK air inlet in the energy storage cabinet through the air distribution device. The air distribution device distributes the air of the air-conditioning air-cooling system to provide the same or different air volumes to the module PACK, so as to perform the air volume distribution of the system according to the requirements at different times.

[0027] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right", etc. are used in the embodiments to describe the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations during the use or operation of the device. For example, if the device in the figure is inverted, the element described as being "below" other elements or features will be positioned "above" other elements or features. Therefore, the exemplary term "lower" can include both the upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0028] Moreover, relational terms such as "first" and "second" are only used to distinguish one component with the same name from another, and do not necessarily require or imply any actual relationship or order between these components.

[0029] The above provides an exemplary description of the present utility model. It should be noted that without departing from the core of the present utility model, any simple deformation, modification, or equivalent replacement that can be made by those skilled in the art without creative efforts falls within the protection scope of the present utility model.
