Description

Technical Field

[0001] This utility model relates to energy storage devices, and more particularly to a liquid-cooled energy storage terminal with a mating extension structure. Background Technology

[0002] Patent document CN215988990U discloses an energy storage terminal, which includes a first frame, a second frame, and multiple panels. The first frame includes a first support frame and a limiting rod; the limiting rod is detachably mounted on the first support frame. The second frame is placed inside the first frame and is detachably mounted on the limiting rod. The second frame is used to house the energy storage power source. Multiple panels are respectively disposed on the top, bottom, and multiple sides of the first frame. The arrangement of the first frame, limiting rod, and second frame improves the impact resistance of the energy storage terminal. By making the first frame the load-bearing body, the service life of the energy storage terminal is increased, further enhancing the safety of the battery system. However, this energy storage terminal can only be installed and used independently, resulting in poor flexibility and hindering its widespread application. Therefore, it is necessary to optimize its structure to overcome the aforementioned shortcomings. Utility Model Content

[0003] The purpose of this invention is to provide a liquid-cooled energy storage terminal with a mating extension structure to improve its flexibility of use.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A liquid-cooled energy storage terminal with a mating extension structure, comprising:

[0006] An energy storage main component, which has an assembly space and contains energy storage cells for storing electrical energy;

[0007] The liquid-cooled temperature control component is installed in the main energy storage component through a detachable connection structure and corresponds to the position of the energy storage cell in the main energy storage component, and can perform cooling operation on the energy storage cell.

[0008] A coolant circulation assembly is installed in the energy storage unit and works in conjunction with a liquid-cooled temperature control assembly. The liquid-cooled circulation assembly supplies coolant to the liquid-cooled temperature control assembly, so that the coolant circulates between the liquid-cooled temperature control assembly and the coolant circulation assembly.

[0009] A plug-in protective assembly is installed in the main energy storage assembly and corresponds to the position of the liquid cooling circulation assembly. The plug-in protective assembly provides shielding protection for the liquid cooling circulation assembly.

[0010] A socket support assembly is installed in the main energy storage assembly. It corresponds to the position of the plug cover assembly and is adapted to the shape of the socket support assembly. The plug cover assembly and the socket support assembly can be connected to each other so that adjacent main energy storage assemblies can be joined together.

[0011] A plug-in buffer assembly is installed in the plug-in cover assembly and is adapted to the shape of the socket support assembly. The plug-in buffer assembly buffers the mating parts of the plug-in cover assembly and the socket support assembly.

[0012] Specifically, the main components of energy storage include:

[0013] The main cabinet is formed by the enclosure of rods and plates. The energy storage cells and liquid cooling temperature control components are installed inside the main cabinet, while the liquid cooling circulation components, plug-in cover components, and socket support components are installed outside the main cabinet. The side of the main cabinet has a plug-in recess. There is a set of plug-in recesses, each extending laterally into the main cabinet and arranged sequentially vertically in the main cabinet, separating adjacent energy storage cells.

[0014] The liquid cooling temperature control components include:

[0015] The liquid cooling module is provided in a set. Each liquid cooling module is adapted to the shape of the plug-in recess. Its inner end is inserted into the plug-in recess and abuts against the adjacent energy storage cell. Its outer end is connected to the outer wall of the main cabinet by locking bolts. The liquid cooling module performs cooling and temperature reduction operation on the energy storage cell in the main cabinet.

[0016] The coolant circulation assembly includes:

[0017] The circulating unit is installed on the top of the main cabinet, protruding outwards from the main cabinet and connected to the liquid cooling module through pipes. The circulating unit supplies coolant to the liquid cooling module, allowing the coolant to circulate between the liquid cooling module and the circulating unit.

[0018] The plug-in cover assembly includes:

[0019] The plug-in protrusion ring is installed on the top of the main cabinet, surrounds the outside of the circulating host, and protrudes upwards from the main cabinet. Its height is greater than that of the circulating host, and the plug-in protrusion ring provides shielding protection for the circulating host.

[0020] The socket support assembly includes:

[0021] The socket protrusion ring is installed at the bottom of the main cabinet and protrudes downwards from the main cabinet. Its shape is adapted to the plug-in protrusion ring. The plug-in protrusion ring on the adjacent main cabinet can be inserted into the socket protrusion ring. The height of the socket protrusion ring is less than the height of the plug-in protrusion ring to avoid the bottom of the adjacent main cabinet from applying pressure to the circulating host, so as to ensure the safety of the energy storage cell.

[0022] The plug-in buffer assembly includes:

[0023] The buffer washer is installed on the top of the main cabinet and covers the outer wall of the plug-in protrusion ring. It is made of elastic material. When the plug-in protrusion ring is inserted into the socket protrusion ring, the buffer washer is placed between the main cabinet and the socket protrusion ring. The buffer washer buffers the end face of the main cabinet and the socket protrusion ring to ensure the safety of the energy storage cell.

[0024] In one embodiment of this utility model, a forklift insertion hole is provided on the side of the socket protrusion ring for inserting forklift forks to safely and stably transport the main cabinet.

[0025] The advantages of this utility model are:

[0026] The liquid-cooled temperature control components of this energy storage terminal are installed in a detachable manner, facilitating disassembly, replacement, and maintenance. The liquid-cooled module is in close contact with the energy storage cells, enabling efficient cooling, preventing cell overheating, and improving system safety and lifespan. Coolant circulation is achieved through the circulation unit and pipelines, ensuring stable heat dissipation. The mating structure of the plug-in cover assembly and the socket support assembly allows for quick connection between adjacent energy storage main components, facilitating expansion and assembly. The mating design of the socket protrusion ring and the plug protrusion ring prevents adjacent cabinets from exerting pressure on the circulation unit, ensuring structural stability. The buffer gaskets are made of elastic material, effectively absorbing vibration and impact, protecting the energy storage cells and the main cabinet, and allowing the system to flexibly adjust energy storage capacity and cooling capacity according to needs.
