Cooling Pipe Structure, Liquid Cooling Plate and Battery System

A liquid cooling plate, comprising a cooling pipe structure and a liquid cooling plate body, wherein the cooling pipe structure comprises:

• a cooling pipe set, wherein the cooling pipe set comprises at least one cooling pipe, a flow direction of liquid in the cooling pipe is defined as a first direction, the cooling pipes are arranged in a tree-like structure from a side to an opposite side along the first direction, a side of the tree-like structure is a tree-like beginning, and an opposite side thereof is a tree-like end;
• a pipe inlet, wherein the pipe inlet is in communication with a side of the tree-like beginning of the cooling pipe in the cooling pipe set;
• and
• a pipe outlet, wherein the pipe outlet is in communication with a side of the tree-like end of the cooling pipe in the cooling pipe set,
• wherein the cooling pipe set is abutted against or embedded into at least one side surface of the liquid cooling plate body.

A battery system, comprising a cell housing, a set of cells, and a liquid cooling plate, wherein the liquid cooling plate comprises a cooling pipe structure and a liquid cooling plate body, wherein the cooling pipe structure comprises:

• a cooling pipe set, wherein the cooling pipe set comprises at least one cooling pipe, a flow direction of liquid in the cooling pipe is defined as a first direction, the cooling pipes are arranged in a tree-like structure from a side to an opposite side along the first direction, a side of the tree-like structure is a tree-like beginning, and an opposite side thereof is a tree-like end;
• a pipe inlet, wherein the pipe inlet is in communication with a side of the tree-like beginning of the cooling pipe in the cooling pipe set;
• and
• a pipe outlet, wherein the pipe outlet is in communication with a side of the tree-like end of the cooling pipe in the cooling pipe set,
• wherein the cooling pipe set is abutted against or embedded into at least one side surface of the liquid cooling plate body, wherein the set of cells and the liquid cooling plate body are provided in the cell housing, and the liquid cooling plate body is positioned on a top or bottom of the set of cells.
