The liquid cooling plate body is composed of four transverse plate segments, one longitudinal plate segment 1, two longitudinal plate segments 2, two longitudinal plate segments 3 and ten arc-shaped transition plate segments, and the four transverse plate segments are arranged side by side and equidistantly; a longitudinal plate segment 1 is provided between the corresponding ports of the two middle transverse plate segments, and one side port of the longitudinal plate segment 1 is connected to the port of one of the transverse plate segments through an arc-shaped transition plate segment, and the other side port of the longitudinal plate segment 1 is connected to the port of the other transverse plate segment through an arc-shaped transition plate segment. At this time, the two middle transverse plate segments, one longitudinal plate segment 1 and the corresponding two arc-shaped transition plate segments form a battery cooling chamber 1; the two outer transverse plate segments are respectively provided with a longitudinal plate segment 2 between the corresponding ports of the adjacent transverse plate segments, and one side port of the longitudinal plate segment 2 is connected to the corresponding transverse plate segment on the outer side through an arc-shaped transition plate segment.

The longitudinal plate segment one and the longitudinal plate segment two are located on both sides of the transverse plate segment, and the other side ports of the two transverse plate segments located on the outside are respectively connected to the one side port of the corresponding longitudinal plate segment three through an arc-shaped transition plate segment. The two longitudinal plate segments three are located on both sides of the longitudinal plate segment one. At this time, a transverse plate segment located on the outside, the transverse plate segment adjacent to the transverse plate segment on the outside, a corresponding longitudinal plate segment two, a corresponding longitudinal plate segment three and the corresponding two arc-shaped transition plate segments form a battery cooling chamber two; the design that the other side ports of the two longitudinal plate segments three are respectively connected to one side port of a corresponding liquid cooling plate water chamber through an arc-shaped transition plate segment is one of the technical features of the present utility model.The purpose of such design is that: the liquid cooling plate body is composed of four transverse plate segments, one longitudinal plate segment 1, two longitudinal plate segments 2, two longitudinal plate segments 3 and ten arc-shaped transition plate segments, and the four transverse plate segments are arranged side by side and equidistantly; a longitudinal plate segment 1 is provided between the corresponding ports of the two middle transverse plate segments, and one side port of the longitudinal plate segment 1 is connected to the port of one of the transverse plate segments through an arc-shaped transition plate segment, and the other side port of the longitudinal plate segment 1 is connected to the port of the other transverse plate segment through an arc-shaped transition plate segment.

In addition, a new type of serpentine bending side cooling liquid cooling plate for energy storage only requires bending (liquid cooling plate body) and welding of inlet and outlet water pipes (welding of liquid cooling plate body and two liquid cooling plate water chambers).
