Liquid cooling system and energy storage system

An energy storage system using a liquid cooling system for cooling a plurality of heating units each having an identical cooling flow channel provided with a liquid inlet and a liquid outlet;

• wherein the liquid cooling system comprises:
• a cooling liquid circulating supply device provided with a liquid supply port and a liquid return port;
• and
• a pipeline system including a liquid supply pipe, a liquid return pipe, and a flow distribution subsystem;
• one end of the liquid supply pipe communicates with the liquid supply port, and the other end is connected to the flow distribution subsystem at a total flow distribution end;
• one end of the liquid return pipe communicates with the liquid return port, and the other end is connected to the flow distribution subsystem at a total liquid collection end;
• the flow distribution subsystem connects the total flow distribution end and the liquid inlet of each heating unit and connects the total liquid collection end and the liquid outlet of each heating unit;
• in the flow distribution subsystem, the plurality of heating units have the same liquid passage length;
• the liquid passage length of the heating unit is equal to the sum of the length of pipeline between the liquid inlet of the heating unit and the total flow distribution end and the length of pipeline between the liquid outlet of the heating unit and the total liquid collection end;
• wherein the cooling liquid circulating supply device is located on one side of the pipeline system along a length direction;
• the total flow distribution end and the total liquid collection end are respectively located at two ends of the pipeline system along the length direction;
• the flow distribution subsystem comprises a first pipeline connecting the liquid inlet of each heating unit and the total flow distribution end, and a second pipeline connecting the liquid outlet of each heating unit and the total liquid collection end;
• the first pipeline comprises a liquid distribution pipe located in the first plane, liquid distribution branch pipes extending along a height direction perpendicular to the first plane, and liquid inlet pipes;
• the second pipeline comprises a liquid collection pipe located in the second plane, liquid collection branch pipes extending along the height direction, and liquid outlet pipes;
• the liquid distribution pipe consists of a first segment, a second segment, and a third segment;
• the first segment and the third segment are parallel to each other and both extend in the length direction, the liquid distribution branch pipes are connected, in parallel, to the first segment and the third segment;
• the second segment extends along a width direction, two ends of the second segment respectively communicates with the first segment and the third segment, and the second segment intersects with the liquid supply pipe at the total flow distribution end;
• the liquid collection pipe consists of a fourth segment, a fifth segment, and a sixth segment;
• the fourth segment and the sixth segment are parallel to each other and both extend in the length direction, the liquid collection branch pipes are connected, in parallel, on the fourth segment and the sixth segment;
• the fifth segment extends along the width direction, two ends of the fifth segment respectively communicates with the fourth segment and the sixth segment, and the fifth segment intersects with the liquid return pipe at the total liquid collection end.
