1. A composite VC heat sink containing a copper/diamond composite wick structure, comprising a lower shell plate, wherein
the lower shell plate is provided with a recess at a center position of an inner surface and provided with a boss with a same plane size as the recess at a center position of an outer surface,
a surface of the boss or a surface of the recess is provided with a copper/diamond composite plate; when the surface of the boss is provided with the copper/diamond composite plate, the surface of the recess is directly provided with the copper/diamond composite wick structure; and when the surface of the recess is provided with the copper/diamond composite plate, the copper/diamond composite wick structure is disposed on a surface of the copper/diamond composite plate,
the copper/diamond composite wick structure comprises a three-dimensional porous structure and uses a first copper/diamond sintered body as a matrix, and
a surface of the matrix is provided with a diamond layer, and a surface of the diamond layer is provided with a metal hydrophilic layer.
