Claim of US Patent No. 11,032,940

1. A cooling plate comprising:first comb tooth flow paths extending from a first common flow path toward an inside of a flat surface parallel to a heat receiving surface in a comb-teeth shape;
second comb tooth flow paths extending from a second common path toward the inside of the flat surface in a comb-teeth shape and being alternately adjacent to the first comb tooth flow paths;
first vertical flow paths each of which extends from a representative one of the first comb tooth flow paths toward a side of the heat receiving surface;
second vertical flow paths each of which extends from a representative one of the second comb tooth flow paths toward the side of the heat receiving surface;
first outer flow paths each of which extends from a representative one of the first vertical flow paths toward an outside of the flat surface;
second outer flow paths each of which extends from a representative one of the second vertical flow paths toward the outside of the flat surface and that are alternately adjacent to the first outer flow path;
first coupling flow paths each of which extends from a representative one of the first comb tooth flow paths or a representative one of the first outer flow paths toward the side of the heat receiving surface;
second coupling flow paths each of which extends from a representative one of the second comb tooth flow paths or a representative one of the second outer flow paths toward the side of the heat receiving surface and that are alternately adjacent to the first coupling flow path; and
heat receiving flow paths each of which communicates with a representative one of the first coupling flow paths and a representative one of the second coupling flow paths to receive heat of the heat receiving surface.
