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 module structure. Background Art

[0002] Battery heat dissipation is the most important component of the battery module. Generally speaking, air cooling or liquid cooling is used for heat dissipation. The air cooling structure is usually simpler and cheaper than the liquid cooling structure. The liquid cooling structure is usually more efficient than the air cooling structure because the liquid has better conductivity in heat transfer. With the development of new energy, the battery module has higher requirements for heat dissipation. Therefore, the heat dissipation methods of air cooling and liquid cooling structures have also begun to develop.

[0003] Current power supply modules, such as energy storage power supply boxes, battery boxes, and mobile power supplies, are usually equipped with several battery packs. Due to the need to save internal space, most current heat dissipation methods that combine air cooling and liquid cooling use the entire box or cabinet to dissipate heat. This heat dissipation method has significantly improved the effect of traditional heat dissipation using only air cooling or liquid cooling. However, heat will still accumulate inside the battery pack, especially the battery pack, due to the heating of the batteries, and the above-mentioned heat dissipation method cannot promptly and effectively export the heat inside the battery pack. Therefore, the utility model proposes a new solution. Utility Model Content

[0010] Further to this solution, the guide plate and the heat conducting plate are both hollow inside, and the conduit is located at the top of the guide plate and the heat conducting plate.

[0016] Further to this solution, a partition cavity and a heat conduction cavity are provided inside the liquid cooling plate;

DETAILED DESCRIPTION

[0026] 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.

[0027] 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.

[0028] 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.

[0029] like Figure 1-3 As shown, the utility model provides a technical solution: the air-cooled and liquid-cooled module structure integrates air cooling and liquid cooling, aiming to improve the heat dissipation effect of the battery module. The main components of the structure include a number of battery blocks 8, an air cooling mechanism and a liquid cooling mechanism;

[0030] like Figure 2As shown, the liquid cooling mechanism is the core part of the air-cooled and liquid-cooled module structure, which immediately conducts away the large amount of heat generated by the battery block 8. It includes a liquid cooling plate 3 and a heat conduction module. The liquid cooling plate 3 serves as a supporting structure to provide a stable foundation for the liquid cooling mechanism. The heat conduction module is responsible for conducting the heat generated by the battery module. The heat conduction module consists of a heat conduction plate 6 and a flow guide plate 5. The heat conduction plate 6 is tightly attached to the surface of each battery block 8, so that the heat of the battery module can be quickly transferred. After passing through the heat conduction plate 6, the heat conduction liquid flows out of the liquid cooling plate 3 and cooperates with the air cooling mechanism to take away the heat of the battery module.

[0031] Among them, a guide plate 5 is provided between the heat conducting plates 6, and the heat conducting plates 6 are connected to the guide plates 5 through the conduits 602 at both ends. A number of heat conducting protrusions 601 are provided on both sides of the heat conducting plates 6, and gaps are left between the heat conducting protrusions 601 for air circulation. The heat conducting protrusions 601 are attached to the surfaces of adjacent battery blocks 8. This design is conducive to guiding the heat conducting medium to flow inside the heat conducting module, improving the heat dissipation effect, effectively increasing the contact area with the battery block 8, and improving the heat conduction efficiency.

[0032] like Figure 1 and Figure 2 As shown, the air cooling mechanism is responsible for providing flowing air for the liquid cooling mechanism to enhance the cooling effect, and it includes a battery frame 1, a fan 2 and a guide plate 5;

[0033] The battery frame 1 is a container for the battery module, which ensures the stability of the battery block 8 during operation. The battery block 8 is installed in the placement groove 303 of the liquid cooling plate 3. A gap is left between every two battery blocks 8 to facilitate air circulation. Fans 2 are installed at both ends of the battery frame 1. The air supply directions of the two fans 2 are consistent. A number of notches 502 are opened on the guide plate 5 to facilitate air circulation. The air supply directions of the two fans 2 are consistent. After the cold air is introduced at one end, after being heated inside the battery frame 1, the hot air is quickly discharged through the fan 2 at the other end, effectively ensuring the working environment of the battery module.

[0034] like Figure 2 and Figure 3 As shown, a partition cavity 301 and a heat conduction cavity 302 are provided inside the liquid cooling plate 3. The partition cavity 301 is separated from the heat conduction cavity 302 and are respectively connected with the outermost guide plate 5 in the heat conduction module. This structural design allows the bottom of the battery block 8 to be wrapped, which can effectively ensure the working environment of the bottom of the battery block 8. Although the heat dissipation effect of the bottom is weaker than that of the heat conduction module, it also has a considerable heat conduction effect.

[0035] like Figure 3As shown, a liquid inlet hole 4 is provided at one end of the liquid cooling plate 3, which is connected to the compartment 301. A liquid outlet hole 7 is provided at the other end of the liquid cooling plate 3, which is connected to the heat conduction cavity 302. The heat conduction cavity 302 is designed as a one-way channel to guide the heat conduction liquid from the liquid inlet hole 4 to the liquid outlet hole 7 to achieve liquid cooling. A liquid cooling plate 3 is also installed on the top of the battery frame 1, and the battery frame 1 forms an upper and lower seal with the top and bottom liquid cooling plates 3.

[0036] The air-cooled and liquid-cooled module structure effectively improves the heat dissipation effect of the battery module through the combination of liquid cooling and air cooling. In practical applications, this structure helps to extend battery life and ensure stable operation of electronic equipment.

[0037] 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.
