Description

Technical Field

[0001] The utility model relates to the technical field of battery heat dissipation, in particular to an air cooling and liquid cooling structure for a PACK box. Background Art

[0002] Energy storage cabinet is a device used to store energy such as electricity. It is usually composed of batteries, capacitors, thermal energy storage media, etc., and stores and releases energy through a control system. Energy storage cabinets have the advantages of high efficiency, safety, and environmental protection, and are widely used in home, industry, transportation and other fields. Energy storage cabinets will generate a lot of heat during use, which will affect the use of energy storage cabinets and even cause safety hazards. In order to ensure the safe use of battery energy storage cabinets, air cooling and liquid cooling are usually used for heat dissipation;

[0003] For example, the integrated heat dissipation energy storage with air cooling and liquid cooling disclosed in the authorization announcement number CN117477100B discloses heat removal from the inside of the battery energy storage cabinet by air cooling and liquid cooling to maintain a suitable working environment in the energy storage cabinet;

[0004] However, the heat dissipation effect of the above method is limited. The interior of the energy storage cabinet is composed of multiple groups of battery modules, and the heat is mainly generated by the battery modules. Although the heat can be exported to a certain extent through air cooling and liquid cooling, it is not efficient and fast enough. If the heat of the battery module is generated quickly, the effect of this overall heat dissipation method is actually limited. Therefore, in response to this situation, the utility model proposes a new solution. Utility Model Content

[0005] The utility model aims to provide an air-cooling and liquid-cooling structure for a PACK box to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an air cooling and liquid cooling structure for a PACK box, comprising:

[0007] Plug-in box, battery pack, liquid cooling pipe and cooling fan;

[0008] The battery packs are provided with at least two groups, and a gap is provided between the two groups of battery packs to form an air duct;

[0009] The cooling fan is installed on the plug box and is directly opposite to the air duct;

[0010] The liquid cooling pipe is wrapped around the surface of the corresponding battery pack.

[0011] Further to this solution, the plug-in box includes: a side panel, an epoxy resin board and a surrounding edge;

[0012] The battery pack is mounted on an epoxy resin board, wherein the surrounding edges are located on both sides of the battery pack and fixed on the epoxy resin board;

[0013] The heat dissipation fan is installed on a side of the side plate away from the battery pack, and a notch is provided on the side plate to connect the heat dissipation fan and the air duct.

[0014] Further to this solution, the plug box also includes a PC board, both ends of the PC board are connected, and the PC board is fixed to the surrounding edge by screws.

[0015] Further to this solution, the battery pack is composed of a plurality of battery blocks connected in parallel, and an aluminum connecting row is fixed to the bottom of each battery pack, and the middle part of the aluminum connecting row protrudes to form a gap between the battery pack and the PC board.

[0016] Further to this solution, a liquid flow cavity is provided inside the liquid cooling pipe, and two ends of the liquid flow cavity are respectively connected to a water inlet and a water outlet.

[0017] Furthermore, regarding this scheme, the liquid flow cavity forms a multi-layer cavity in the liquid cooling pipe. The heat absorbing medium enters the liquid flow cavity from the water inlet and passes through each layer of the cavity in turn and is discharged from the water outlet. The multi-layer cavity design enables the heat absorbing medium to fully absorb heat during the flow process, thereby improving the heat dissipation effect. The two ends of the liquid flow cavity are respectively connected to the water inlet and the water outlet. The liquid flow cavity is a unidirectional flow channel, forming a closed liquid cooling circulation system.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] The PACK box uses an air-cooling and liquid-cooling structure, which uses plug-in boxes, battery pack distribution, cooling fans and liquid cooling pipes to quickly absorb the heat generated by the battery pack through liquid cooling, and promptly export the heat to the battery module through the cooling fan, which can dissipate heat more quickly and efficiently. At the same time, this structure can optimize the battery space.

[0020] At the same time, the PACK box uses an air-cooling plus liquid-cooling structure to reasonably layout the battery pack, which can not only achieve efficient heat dissipation, but also achieve efficient heat dissipation of the battery pack by air cooling and liquid cooling at the same time in a small space. It is highly practical and has good market prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] It should be noted that, in the description of the present invention, the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0029] Furthermore, it should be understood that for the sake of ease of description, the sizes of the various components shown in the drawings are not drawn according to actual proportions. For example, the thickness or width of certain layers may be exaggerated relative to other layers.

[0030] like Figure 1-5 As shown, the utility model provides a technical solution: the power box structure mainly includes three parts: a plug-in box 1, a battery pack, a liquid cooling pipe 6 and a cooling fan 2. The plug-in box 1 provides an installation platform for the battery pack and the cooling fan 2. The battery pack is composed of two or more groups connected in parallel, and at least two groups are provided. A gap is provided between the two battery packs to form an air duct 5 to improve the heat dissipation effect. The cooling fan 2 is installed on the plug-in box 1, facing the air duct 5, to ensure smooth air flow in the air duct 5.

[0031] like Figure 3 and Figure 5As shown, in order to ensure the smooth implementation of this embodiment, it is necessary to understand that the liquid cooling pipe 6 in the power box is tightly wrapped around the surface of the battery pack, and a liquid flow cavity 601 is provided inside. The two ends of the liquid flow cavity 601 are respectively connected to the water inlet 7 and the water outlet 701. When the liquid cooling system is started, the heat absorbing medium enters the liquid flow cavity 601 through the water inlet 7, flows layer by layer in the multi-layer cavity formed by the liquid flow cavity 601, and is finally discharged from the water outlet 701. In this way, the liquid cooling pipe 6 can effectively transfer the heat generated by the battery pack to the air duct 5 where the cooling fan 2 is located to achieve heat dissipation.

[0032] like Figure 1 and Figure 2 As shown, what needs to be understood about this solution is that the cooling fan 2 is installed on the side panel 101, away from the side of the battery pack, and a notch 106 is provided on the side panel 101, which is connected to the air duct 5 to make the air flow in the air duct 5 smoother. This layout is conducive to improving the heat dissipation efficiency and ensuring the stability and safety of the battery pack during operation. A handle 104 is installed on one side of the side panel 101 to facilitate the removal of the battery module from the energy storage cabinet.

[0033] like Figure 2 and Figure 3 As shown, in order to ensure that this embodiment is the best embodiment, it is necessary to understand that the battery pack is composed of multiple battery blocks 3 connected in parallel, and an aluminum connecting row 4 is fixed at the bottom of each battery pack. The middle part of the aluminum connecting row 4 protrudes, so that a gap is generated between the battery pack and the PC board 105, which is beneficial to the dissipation of heat and facilitates the line connection between the battery blocks 3.

[0034] like Figure 4 As shown, further to this solution, the plug box 1 is composed of a side panel 101, an epoxy resin board 102 and a surrounding edge 103, the battery pack is mounted on the epoxy resin board 102, and the surrounding edge 103 is fixed on both sides of the battery pack. This design not only ensures the stability of the battery pack, but also provides sufficient space for the cooling fan 2.

[0035] like Figure 5 As shown, in order to ensure that this solution is the best preferred solution, it is necessary to understand that a liquid flow cavity 601 is provided inside the liquid cooling pipe 6. The multi-layer cavity design enables the heat-absorbing medium to fully absorb heat during the flow process, thereby improving the heat dissipation effect. The two ends of the liquid flow cavity 601 are respectively connected to the water inlet 7 and the water outlet 701. The liquid flow cavity 601 is a unidirectional flow channel to form a closed liquid cooling circulation system. This power box has an air-cooled and liquid-cooled structure with excellent heat dissipation performance and stability, and provides a good operating environment for electronic equipment.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
