Heat dissipation grooves (33) are provided on the first heat exchange plate (21), the second heat exchange plate (22), the first flow channel plate (23), and the second flow channel plate (24) below the heat dissipation plate (32).

Utility Model Content

[0003] Design objective: To overcome the shortcomings of the prior art, a new type of side cooling device for energy storage is designed that is not only more compact in structure and simpler in water supply structure, but also has a better cooling effect.

[0004] Design scheme: To achieve the above design objectives.

[0005] 1. The side liquid cooling plate has an inlet and an outlet on one side of its front, and an inlet and an outlet on one side of its back. The inlets on the front and back are directly opposite and connected, and the outlets on the front and back are directly opposite and connected. Two corresponding inlets on a pair of adjacent side liquid cooling plates are connected by a T-connector, and two corresponding inlets on other adjacent side liquid cooling plates are each connected by a connecting pipe. Similarly, two corresponding outlets on a pair of adjacent side liquid cooling plates are connected by a T-connector, and two corresponding outlets on other adjacent side liquid cooling plates are each connected by a connecting pipe. The design of sealing the inlets and outlets of the two outermost side liquid cooling plates that are not connected by connecting pipes or T-connectors with plugs is one of the technical features of this utility model. The purpose of this design is as follows: One liquid inlet and one liquid outlet are located on the front side of the side liquid cooling plate, and one liquid inlet and one liquid outlet are located on the back side of the side liquid cooling plate. The liquid inlets on the front and back sides are directly opposite and connected, and the liquid outlets on the front and back sides are directly opposite and connected. Two corresponding liquid inlets on a pair of adjacent side liquid cooling plates are connected by a T-junction pipe, while two corresponding liquid inlets on other adjacent side liquid cooling plates are each connected by a connecting pipe. Similarly, two corresponding liquid outlets on a pair of adjacent side liquid cooling plates are connected by a T-junction pipe, while two corresponding liquid outlets on other adjacent side liquid cooling plates are each connected by a connecting pipe. The two corresponding liquid outlets on the side liquid cooling plates are connected by a connecting pipe; the liquid inlets and outlets of the two outermost side liquid cooling plates that are not connected by connecting pipes or T-connecting pipes are sealed with plugs; since the liquid inlets and outlets of multiple side liquid cooling plates are located on the same side, and multiple side liquid cooling plates achieve unified liquid supply and unified liquid return through multiple connecting pipes and two T-connecting pipes, the structure of the new type of side cooling device for energy storage is more compact, that is, the overall volume of the new type of side cooling device for energy storage is reduced, and the water supply structure of the new type of side cooling device for energy storage with unified liquid supply and unified liquid return is simpler.

[0006] 2. The coolant channel in the side liquid cooling plate includes two U-shaped segments, one C-shaped segment, two straight segments, and two horizontal segments. The two straight segments are arranged along the length of the side liquid cooling plate. The side liquid cooling plate has two U-shaped segments located on both sides of the two straight segments. One end of the straight segment is connected to one end of the adjacent U-shaped segment through a horizontal segment. The other ends of the two U-shaped segments are connected through a C-shaped segment located outside the two horizontal segments. The design that the other end of one straight segment communicates with the liquid inlet on the side liquid cooling plate and the other end of the other straight segment communicates with the liquid outlet on the side liquid cooling plate is the second technical feature of this utility model. The purpose of this design is as follows: the coolant channels in the side liquid cooling plate include two U-shaped sections, one C-shaped section, two straight sections, and two horizontal sections. The two straight sections are arranged along the length of the side liquid cooling plate. The side liquid cooling plate has two U-shaped sections located on both sides of the two straight sections. One end of each straight section is connected to one end of an adjacent U-shaped section via a horizontal section. The other ends of the two U-shaped sections are connected via a C-shaped section located outside the two horizontal sections. The other end of one straight section communicates with the liquid inlet on the side liquid cooling plate, and the other end of the other straight section communicates with the liquid outlet on the side liquid cooling plate. With interconnected cooling channels, this coolant channel structure achieves a uniform cooling effect across the entire side liquid cooling plate. Testing revealed that the temperature difference between the highest and lowest points of a battery (cell) cooled by this novel energy storage side cooling device is no more than 3°C. This significantly improves the temperature uniformity and consistency of the cell, greatly extending battery life and reducing thermal runaway caused by uneven temperature distribution. Furthermore, this coolant channel structure expands the heat exchange area, improves cooling efficiency, shortens cell temperature control time, and enables rapid cooling in extreme conditions such as thermal runaway, effectively blocking abnormal heat conduction. In short, this novel energy storage side cooling device provides excellent cooling for batteries (cells).

[0007] 3. The third technical feature of this utility model is that one side of the side liquid cooling plate has a protruding liquid cooling plate portion, the width of which is smaller than the width of the side liquid cooling plate. The two inlets and two outlets on the side liquid cooling plate are all located on the protruding portion. The purpose of this design is that the protruding portion not only reduces the overall weight of the novel side cooling device for energy storage but also facilitates the installation of connecting pipes and T-joint connecting pipes.

[0008] 4. The design of having two mounting holes on one side of the front of the side liquid cooling plate, with each mounting hole penetrating both sides of the side liquid cooling plate, and two mounting holes on the other side of the front of the side liquid cooling plate, with each mounting hole penetrating both sides of the side liquid cooling plate, is the fourth technical feature of this utility model. The purpose of this design is that, with two mounting holes on one side of the front of the side liquid cooling plate penetrating both sides of the side liquid cooling plate, and two mounting holes on the other side of the front of the side liquid cooling plate penetrating both sides of the side liquid cooling plate, the mounting holes one and two are configured to allow for the clamping connection of multiple side liquid cooling plates after a battery (cell) is placed on a novel energy storage side cooling device via connectors (such as long screws and nuts).

[0009] 5. The design of the two sides of the side liquid cooling plate being horizontal is the fifth technical feature of this utility model. The purpose of this design is that the two sides of the side liquid cooling plate are horizontal, so that the battery (cell) can make surface-to-surface contact with the side liquid cooling plate, thereby ensuring the cooling effect of the novel energy storage side cooling device on the battery (cell).

[0010] Technical Solution: A novel side-cooling device for energy storage includes multiple side liquid-cooled plates, multiple connecting pipes, and two T-connectors. Each side liquid-cooled plate has an inlet and an outlet on its front side and an inlet and an outlet on its back side. The inlets on the front and back sides are directly opposite and connected, as are the outlets on the front and back sides. Two corresponding inlets on a pair of adjacent side liquid-cooled plates are connected by a T-connector, while two corresponding inlets on other adjacent side liquid-cooled plates are each connected by a connecting pipe. Similarly, two corresponding outlets on a pair of adjacent side liquid-cooled plates are connected by a T-connector, while two corresponding outlets on other adjacent side liquid-cooled plates are each connected by a connecting pipe. The inlets and outlets on the two outermost side liquid-cooled plates that are not connected by a connecting pipe or T-connector are sealed with plugs.
